Description

압력지표계Pressure indicator
본 발명은 압력지표계에 관한 것이다.The present invention relates to a pressure indicator system.
일반적으로 멤브레인 압력 센서는 압력 측정 장치(pressure measurement device)가 소정의한 이유 때문에 측정 대상 물질과 직접 연결이 되지 않을 때 측정 대상 물질의 압력을 압력 측정 장치로 전달하는데 사용된다.In general, a membrane pressure sensor is used to transfer the pressure of a substance to a pressure measuring device when the pressure measuring device is not directly connected to the substance to be measured for some reason.
종래의 멤브레인 압력 센서는 근본적으로 서로 멤브레인에 의해 구분되는 두개의 공간이나 챔버를 가지고 있으며, 이들 두 개의 공간이나 챔버 중 어느 하나는 압력을 측정할 물질을 수용하고, 다른 하나는 충진 유체로 채워진다. 이때 물질에 가해지는 압력은 해당 멤브레인의 움직임에 의해 충진 유체에 전달되므로, 물질이 직접적으로 압력 측정 장치에 연결되지 않아도, 물질의 압력을 탐지할 수 있다.Conventional membrane pressure sensors essentially have two spaces or chambers separated by membranes from one another, either of which contains a material for measuring pressure and the other filled with a filling fluid. At this time, since the pressure applied to the material is transferred to the filling fluid by the movement of the membrane, the pressure of the material can be detected even if the material is not directly connected to the pressure measuring device.

하지만, 종래기술에 따른 압력지표계는 하기 선행기술문헌의 특허문헌에 개시된 바와 같이, 멤브레인의 변화하는 곡률을 측정하여 압력을 측정하므로, 멤브레인이 변화한 정도를 측정할 구체적인 전기적, 기계적, 화학적 구성이 필요하다. 또한, 압력 측정 대상체 내부의 유체 압력이 소정의 압력에 도달하였는지를 육안만으로 즉각적으로 파악할 수 없는 문제점이 존재한다.However, since the pressure indicator system according to the prior art measures the pressure by measuring the curvature of the membrane as disclosed in the patent document of the following prior art document, the specific electrical, mechanical, chemical composition to measure the degree of change of the membrane This is necessary. In addition, there is a problem that it is not possible to immediately determine whether the fluid pressure inside the pressure measuring object has reached a predetermined pressure.

도 1a 내지 도 1b는 본 발명에 따른 압력지표계를 도시한 사시도이다.1A to 1B are perspective views illustrating a pressure indicator system according to the present invention.
도 1a 내지 도 1b에 도시된 바와 같이, 본 실시예에 따른 압력지표계(100)는 압력 측정 대상체(300) 내부의 유체(200)의 압력을 받아 변형하는 제1 부재(110), 및 상기 제1 부재(110)를 사이에 두고, 상기 압력 측정 대상체(300)의 맞은편에 배치되는 하우징(120)을 포함한다. As shown in Figure 1a to Figure 1b, the pressure indicator 100 according to the present embodiment is a first member 110 that is deformed under the pressure of the fluid 200 inside the pressure measurement object 300, and the The housing 120 is disposed to face the pressure measuring object 300 with the first member 110 therebetween.
상기 압력 측정 대상체(300)는, 예를 들어, 본 발명에 따른 압력지표계(100)가 압력을 측정할 휴대용 정수용기 또는 자전거 및 자동차의 타이어 등이다. 상기 제1 부재(110)는, 유체(200)의 압력에 의해 팽창함으로써, 소정의 압력에 도달하였는지 육안으로 확인할 수 있도록 한다. 여기서, 제1 부재(110)는 압력 측정 대상체(300) 내부의 유체(200)의 압력에 직접적으로 영향을 받을 수 있도록 배치된다. 따라서, 유체(200)와 직접적으로 맞닿을 수 있도록 배치되는 것이 바람직하다.The pressure measuring object 300 may be, for example, a portable water container or a tire of a bicycle and a vehicle, in which the pressure indicator 100 according to the present invention measures the pressure. The first member 110 is expanded by the pressure of the fluid 200, so that it can be visually confirmed whether a predetermined pressure has been reached. Here, the first member 110 is disposed so as to be directly affected by the pressure of the fluid 200 inside the pressure measuring object 300. Therefore, it is preferable to be disposed so as to be in direct contact with the fluid 200.
또한, 제1 부재(110)는 유체(200)의 압력을 받아 팽창되어야 하므로, 예를 들어, 탄성을 가진 막으로 구비될 수 있다. 또한, 유체(200)의 압력을 균일하게 받기 위해 평면 형태로 구비되는 것이 바람직하다.In addition, since the first member 110 needs to be expanded under the pressure of the fluid 200, for example, the first member 110 may be provided as an elastic membrane. In addition, in order to receive the pressure of the fluid 200 uniformly, it is preferably provided in a planar shape.
상기 하우징(120)은 제1 부재(110)가 일정부피 이상으로 팽창하는 것을 제어하고, 제1 부재(110)의 팽창한 형상을 외부에서 관측할 수 있도록 한다. 제1 부재(110)가 유체(200)의 압력에 따라 무한히 팽창을 하면 손상이 될 우려가 있으므로, 하우징(120)은 제1 부재(110)의 부피 팽창을 제어한다. The housing 120 controls the expansion of the first member 110 by a predetermined volume or more, and allows the expanded shape of the first member 110 to be observed from the outside. Since the first member 110 may be damaged indefinitely according to the pressure of the fluid 200, the housing 120 controls the volume expansion of the first member 110.
여기서, 하우징(120)은 제1 부재(110)를 사이에 두고, 압력 측정 대상체(300)의 맞은편에 배치되면서, 제1 부재(110)를 덮는다. 또한, 하우징(120)의 테두리는 제1 부재(110)의 테두리와 연결될 수 있다. 따라서, 후술하는 바와 같이, 유체(200)의 압력이 증가하면, 제1 부재(110)는 반구 또는 포물선 형태로 팽창하고, 하우징(120)의 내면에 접촉할 때까지 팽창할 수 있다.Here, the housing 120 covers the first member 110 while being disposed opposite the pressure measuring object 300 with the first member 110 interposed therebetween. In addition, the edge of the housing 120 may be connected to the edge of the first member 110. Therefore, as will be described later, when the pressure of the fluid 200 increases, the first member 110 may expand in a hemispherical or parabolic form and expand until it contacts the inner surface of the housing 120.
또한, 하우징(120)은 투명 또는 반투명의 재질로 형성되어, 외부에서도 육안으로 제1 부재(110)가 팽창하는 것을 관측 가능하도록 할 수 있다. 이때, 사용자는 제1 부재(110)가 팽창하는 것을 통해, 대상체의 내부 압력이 증가하고 있다는 것을 인지할 수 있고, 이에 따라 적절한 대처를 취할 수 있다.In addition, the housing 120 may be formed of a transparent or translucent material, so that the first member 110 can be observed to be visually expanded from the outside. In this case, the user may recognize that the internal pressure of the object is increasing through the expansion of the first member 110, and thus, the user may take appropriate measures.
추가적으로, 도 1a 내지 도 1b에 도시된 바와 같이, 상기 하우징(120)의 표면에는 제1 홀(122)이 형성될 수 있다.In addition, as illustrated in FIGS. 1A to 1B, a first hole 122 may be formed on the surface of the housing 120.
상기 제1 홀(122)은 하우징(120) 내부와 외부 사이에 통기성을 확보하여, 하우징(120) 내부의 압력을 외부와 같이 대기압으로 유지하는 역할을 한다. 팽창하는 부피는 내부 및 외부의 압력에 따라서 달라지는데, 제1 부재(110)의 팽창이 비록 밀폐된 하우징(120)내에서 이루어지지만, 대기압 하에서 팽창하는 것과 동일하게 한다. 따라서, 사용자는 육안으로 유체(200)의 압력이 소정의 압력에 도달하였음을 파악할 수 있다. 이때, 제1 홀(122)은 하우징(120) 표면 어느 곳에나 형성될 수 있으며, 제1 부재(110)가 팽창하여 제1 홀(122)을 통해 돌출되지 않도록, 작게 형성하여야 하고, 바람직하게는 직경이 0.5mm 이하로 형성될 수 있다.The first hole 122 secures air permeability between the inside and the outside of the housing 120, and maintains the pressure inside the housing 120 at atmospheric pressure as the outside. The volume of expansion depends on the internal and external pressures, such that the expansion of the first member 110 is the same as the expansion under atmospheric pressure, although the expansion in the enclosed housing 120 takes place. Therefore, the user may visually recognize that the pressure of the fluid 200 has reached a predetermined pressure. In this case, the first hole 122 may be formed anywhere on the surface of the housing 120, and should be formed small so that the first member 110 does not expand and protrude through the first hole 122. May be formed to a diameter of 0.5mm or less.
또한, 도 1a 내지 도 1b에 도시된 바와 같이, 본 발명에 따른 압력지표계(100)는, 양단이 개방되고, 상기 압력 측정 대상체(300)와 상기 제1 부재(110)를 연결하는 연결구(150)를 포함하고, 상기 제1 부재(110)는 상기 연결구(150)의 일단을 밀봉하도록 상기 연결구(150)의 상기 일단에 결합될 수 있다.In addition, as shown in Figures 1a to 1b, the pressure indicator system 100 according to the present invention, both ends are open, the connector for connecting the pressure measuring object 300 and the first member 110 ( 150, and the first member 110 may be coupled to the one end of the connector 150 to seal one end of the connector 150.
제1 부재(110)를 직접적으로 압력 측정 대상체(300)에 결합시킬 수도 있으나, 내부 유체(200)의 압력의 증가로 제1 부재(110)가 팽창하면, 제1 부재(110)와 압력 측정 대상체(300)의 결합이 약하여, 제1 부재(110)가 분리될 우려가 있다. 따라서, 별도의 연결구(150)를 구비하여, 압력 측정 대상체(300), 연결구(150) 및 제1 부재(110)를 결합할 수 있다.Although the first member 110 may be directly coupled to the pressure measuring object 300, when the first member 110 expands due to an increase in the pressure of the internal fluid 200, the first member 110 and the pressure measurement may be performed. Since the coupling of the object 300 is weak, there is a fear that the first member 110 is separated. Therefore, by providing a separate connector 150, the pressure measuring object 300, the connector 150 and the first member 110 can be coupled.
예를 들어, 연결구(150)의 외벽에 나사선을 형성하여 볼트 체결 방식으로 연결구(150)와 압력 측정 대상체(300)를 결합할 수 있으며, 다만, 권리범위는 반드시 이에 한하지 않는다.For example, by forming a screw thread on the outer wall of the connector 150 may be coupled to the connector 150 and the pressure measuring object 300 by the bolt fastening method, but the scope of rights is not necessarily limited thereto.
도 2는 본 발명에 따른 압력지표계의 실시를 도시한 정면도이다.2 is a front view showing the implementation of the pressure indicator system according to the present invention.
한편, 하우징(120)의 부피는, 소정의 압력에서 제1 부재(110)가 팽창하는 부피와 동일하게 할 수 있다. 따라서, 확인하고자 하는 소정의 압력하에서, 제1 부재(110)의 재질에 따른 탄성률을 고려하여 제1 부재(110)가 팽창하는 부피를 계산하고, 그 팽창 부피와 하우징(120)의 부피를 동일하게 하여 하우징(120)을 제작할 수 있다.On the other hand, the volume of the housing 120 may be equal to the volume of the first member 110 expands at a predetermined pressure. Therefore, under the predetermined pressure to be checked, the volume of the first member 110 is calculated in consideration of the elastic modulus according to the material of the first member 110, and the expansion volume is equal to the volume of the housing 120. The housing 120 can be manufactured.
구체적으로, 도 2에 도시된 바와 같이, 하우징(120)은 반구 형상이고, 하우징(120)의 표면에 제2 홀(124)이 형성될 수 있다. Specifically, as shown in FIG. 2, the housing 120 is hemispherical in shape, and the second hole 124 may be formed on the surface of the housing 120.
상기 제2 홀(124)은 유체(200)의 압력이 소정의 압력을 초과하면 제1 부재(110)가 팽창하여 외부로 돌출되는 공간을 제공하여, 제1 부재(110)를 육안으로 관측할 수 있도록 한다.When the pressure of the fluid 200 exceeds a predetermined pressure, the second hole 124 provides a space in which the first member 110 expands and protrudes to the outside to observe the first member 110 visually. To help.
구체적으로, 제1 부재(110)가 유체(200)의 압력을 받으면, 제1 부재(110)의 테두리는 고정이 되어 있으므로, 반구 또는 포물선 형태로 팽창하게 된다. 따라서, 제1 부재(110)가 하우징(120)의 내면에 밀착하면, 제1 부재(110)의 팽창부피와 하우징(120)의 부피가 동일한 것이고, 소정의 압력에 도달했음을 알 수 있다. Specifically, when the first member 110 is subjected to the pressure of the fluid 200, since the edge of the first member 110 is fixed, it expands in the hemispherical or parabolic form. Therefore, when the first member 110 is in close contact with the inner surface of the housing 120, it can be seen that the volume of the expansion volume of the first member 110 and the volume of the housing 120 are the same and have reached a predetermined pressure.
이때, 유체(200)의 압력이 소정의 압력을 초과하면, 제1 부재(110)는 더욱 팽창하게 되므로, 제2 홀(124)을 통해 제1 부재(110)의 일부가 돌출된다. 이러한 돌출된 제1 부재(110)를 육안으로 인식하여, 사용자는 대상체의 내부 압력이 소정의 압력을 초과하였음을 알 수 있다.At this time, when the pressure of the fluid 200 exceeds the predetermined pressure, the first member 110 is further expanded, so that a part of the first member 110 protrudes through the second hole 124. By visually recognizing the protruding first member 110, the user may know that the internal pressure of the object exceeds a predetermined pressure.
결국, 제1 부재(110)가 팽창하여 하우징(120)의 내면에 접촉하게 되면, 사용자가 알고자 하는 소정의 압력에 도달하였음을 알 수 있다.As a result, when the first member 110 is inflated to contact the inner surface of the housing 120, it can be seen that the user has reached a predetermined pressure.
한편, 도 2에 도시된 바와 같이, 제2 홀(124)은 반구 형상의 하우징(120)의 정점에 형성될 수 있다. 상술한 바와 같이, 제1 부재(110)가 압력을 받으면 반구 또는 포물선 형태로 팽창하고, 제1 부재(110)의 중심부부터 부풀어 오른다. 또한, 제1 부재(110)가 하우징(120)의 내부에 완전히 밀착한 후에, 소정의 압력을 초과하여 계속 팽창할 때도, 제1 부재(110)의 중심부부터 부풀어 오른다. 따라서, 제2 홀(124)도 이에 맞추어 하우징(120)의 최상단인 정점에 형성될 수 있다. Meanwhile, as shown in FIG. 2, the second hole 124 may be formed at the apex of the hemispherical housing 120. As described above, when the first member 110 is subjected to pressure, the first member 110 expands in the hemispherical or parabolic form, and swells from the center of the first member 110. In addition, after the first member 110 is completely in close contact with the inside of the housing 120, even when continuously expanding beyond a predetermined pressure, the first member 110 swells from the center of the first member 110. Accordingly, the second hole 124 may also be formed at the top of the housing 120 accordingly.
결국, 내부 유체(200)의 압력이 소정의 압력을 초과하는 즉시, 제1 부재(110)의 일부가 제2 홀(124)을 통해 외부로 노출되어, 사용자는 이를 육안으로 관찰할 수 있으므로, 소정의 압력을 초과하였음을 명확히 인지할 수 있다.As a result, as soon as the pressure of the inner fluid 200 exceeds the predetermined pressure, a part of the first member 110 is exposed to the outside through the second hole 124, so that the user can observe it visually. It can be clearly appreciated that the predetermined pressure has been exceeded.
도 3은 압력지표계의 실시를 촬영한 사진이고, 도 4는 본 발명의 제1 변형예에 따른 압력지표계의 사시도이다.3 is a photograph photographing the implementation of the pressure indicator system, Figure 4 is a perspective view of a pressure indicator system according to a first modification of the present invention.
추가적으로, 상기 하우징(120)은 상기 제2 홀(124)로부터 상측으로 연장되고, 상부면은 폐쇄되며 측면에 제3 홀(132)이 형성된 감지부(130)를 포함할 수 있다. In addition, the housing 120 may include a sensing unit 130 extending upward from the second hole 124, and having an upper surface closed and having a third hole 132 formed at a side surface thereof.
도 3에 나타난 바와 같이, 상부에서 관측시, 유체(200)의 압력이 증가하여도, 제1 부재(110)가 부풀어오르는 형상이 매우 유사하다. 따라서, 사용자가 상부에서 관측시, 유체(200)의 압력이 어느 정도 증가하였는지 파악이 어려운 문제점이 존재한다.As shown in FIG. 3, when viewed from the top, even when the pressure of the fluid 200 increases, the shape in which the first member 110 swells is very similar. Therefore, when the user observes from the top, there is a problem that it is difficult to determine how much the pressure of the fluid 200 increased.
따라서, 도 4에 도시된 바와 같이, 상부면은 폐쇄되고, 측면에 제3 홀(132)을 형성된 감지부(130)를 구비하여, 제1 부재(110)가 제3 홀(132)을 통해서 측면으로 팽창하게 할 수 있다. 따라서, 유체(200)의 압력이 증가하면, 제1 부재(110)의 팽창이 측면의 제3 홀(132)을 통해서 형성되므로, 사용자가 상부에서 육안으로 관측시, 유체(200)의 압력이 증가한 정도를 더욱 명확히 파악할 수 있다.Therefore, as shown in FIG. 4, the upper surface is closed and the sensing unit 130 having the third hole 132 is formed on the side thereof, so that the first member 110 passes through the third hole 132. To expand laterally. Therefore, when the pressure of the fluid 200 increases, since the expansion of the first member 110 is formed through the third hole 132 on the side, when the user observes with the naked eye from above, the pressure of the fluid 200 increases. The extent of the increase can be identified more clearly.
도 5a 내지 도 5b는 본 발명의 제2 변형예에 따른 압력지표계의 단면도이다.5A to 5B are cross-sectional views of a pressure indicator system according to a second modification of the present invention.
한편, 하우징(120)은 반구 형상이고, 하우징(120)의 표면에 투명 또는 반투명 재질의 관측창(140)이 형성될 수 있다. 즉, 앞선 실시예와 달리, 하우징(120)에 개방된 홀이 형성되는 것이 아니라, 하우징(120) 내부의 제1 부재(110)의 팽창을 관측할 수 있도록 관측창(140)이 형성될 수 있다. 이때, 제1 부재(110)는 팽창하더라도, 하우징(120)이 밀폐되어 있으므로, 제1 부재(110)가 하우징(120) 외부로 돌출될 수 없다. 또한, 제1 부재(110)는 반구 또는 포물선 형태로 팽창하므로, 관측창(140)은 하우징(120)의 정점에 형성될 수 있다.On the other hand, the housing 120 has a hemispherical shape, the observation window 140 of the transparent or translucent material may be formed on the surface of the housing 120. That is, unlike the previous embodiment, the opening 120 is not formed in the housing 120, but the observation window 140 may be formed to observe the expansion of the first member 110 inside the housing 120. have. At this time, even if the first member 110 is expanded, the housing 120 is sealed, so that the first member 110 cannot protrude outside the housing 120. In addition, since the first member 110 expands in a hemispherical or parabolic shape, the observation window 140 may be formed at the apex of the housing 120.
또한, 하우징(120)에서 관측창(140) 외 부분을 불투명하게 하면, 제1 부재(110)가 팽창하여 관측창(140)의 내면에 접촉하였을 때, 제1 부재(110)와, 하우징(120)의 관측창(140) 외 부분이 서로 더욱 명확히 대비될 수 있다. 따라서, 내부의 유체(200)가 소정의 압력에 도달하였음을 육안으로 더욱 명확히 식별할 수 있다.In addition, when the outer portion of the observation window 140 is opaque in the housing 120, when the first member 110 expands and contacts the inner surface of the observation window 140, the first member 110 and the housing ( The outer portion of the observation window 140 of 120 may be more clearly contrasted with each other. Thus, it can be more clearly identified visually that the fluid 200 inside has reached a predetermined pressure.
도 6a 내지 도 6b는 본 발명의 제3 변형예에 따른 압력지표계의 단면도이다.6A to 6B are cross-sectional views of a pressure indicator system according to a third modification of the present invention.
도 6a 내지 도 6b에 도시된 바와 같이, 본 발명에 따른 압력지표계(100)에 있어서, 상기 하우징(120)은 투명 또는 반투명의 재질로 구비되고, 상기 제1 부재(110)를 덮고, 상기 압력 측정 대상체(300)에 결합하여 고정되는 바디부(162), 및 상기 바디부(162)와 연결되어 상기 바디부(162)를 사이에 두고 상기 제1 부재(110)의 맞은 편에 배치되며, 압력 측정 대상체(300) 내부의 압력에 따라 변형되고, 상기 바디부(162)와 구별되는 표시부(164)를 포함하는 제2 부재(160)를 포함할 수 있다.As shown in Figure 6a to 6b, in the pressure indicator system 100 according to the present invention, the housing 120 is provided with a transparent or translucent material, covering the first member 110, A body part 162 coupled to and fixed to the pressure measuring object 300, and connected to the body part 162 and disposed opposite the first member 110 with the body part 162 interposed therebetween. The second member 160 may be deformed according to the pressure inside the pressure measuring object 300 and include a display unit 164 distinguished from the body unit 162.
상기 바디부(162)는 압력 측정 대상체(300) 또는 제1 부재(110)와 결합되어 테두리가 고정되고, 유체(200)의 압력이 가해져도 팽창하지 않는 재질로 구성될 수 있다. 또한, 표시부(164)는 유체(200)의 압력에 의해 팽창할 수 있는 탄성막 등의 재질로 구비되는 것이 바람직하다. 따라서, 유체(200)의 압력이 증가하여 표시부(164)가 팽창되면, 외부에서 표시부(164)를 명확하게 관측할 수 있다. 이때, 표시부(164)는 발광물질 등으로 구성하여 바디부(162)와 명확히 구별될 수 있도록 한다. 다만, 본 발명에 따른 압력지표계(100)의 권리범위는 반드시 이러한 예시에 한하지 않는다.The body portion 162 may be made of a material that is combined with the pressure measuring object 300 or the first member 110 to fix the rim and does not expand even when the pressure of the fluid 200 is applied. In addition, the display unit 164 may be made of a material such as an elastic membrane that can expand due to the pressure of the fluid 200. Therefore, when the pressure of the fluid 200 increases and the display unit 164 is expanded, the display unit 164 can be clearly observed from the outside. In this case, the display unit 164 is made of a light emitting material or the like to be clearly distinguished from the body unit 162. However, the scope of the right of the pressure indicator system 100 according to the present invention is not necessarily limited to this example.
구체적으로, 도 6b에 도시된 바와 같이, 압력 측정 대상체(300) 내부의 유체(200)의 압력이 증가하면, 제1 부재(110)가 팽창하는 방향과 동일한 방향으로 표시부(164)도 팽창한다. 여기서, 하우징(120)이 투명 또는 반투명의 재질로 구비되어 외부에서 표시부(164)의 관측이 가능하다. 따라서, 사용자는 육안으로 표시부(164)를 식별함으로써 내부의 압력이 증가하였음을 인지할 수 있다. 또한, 표시부(164)의 탄성률을 고려하여 소정의 압력에 따른 표시부(164)의 위치를 미리 예측하고, 표시부(164)가 그 위치에서 육안으로 식별되는지 여부를 확인하여, 유체(200)의 압력이 소정의 압력에 도달하였는지 여부를 파악할 수 있다.Specifically, as shown in FIG. 6B, when the pressure of the fluid 200 inside the pressure measuring object 300 increases, the display unit 164 also expands in the same direction as the direction in which the first member 110 expands. . Here, the housing 120 is made of a transparent or translucent material, it is possible to observe the display unit 164 from the outside. Therefore, the user can recognize that the pressure inside the body has increased by visually identifying the display unit 164. In addition, the position of the display unit 164 according to the predetermined pressure is predicted in advance in consideration of the elastic modulus of the display unit 164, and whether the display unit 164 is visually identified at the position is checked to determine the pressure of the fluid 200. It is possible to grasp whether or not this predetermined pressure has been reached.
도 7은 본 발명의 제4 변형예에 따른 압력지표계의 단면도이다.7 is a sectional view of a pressure indicator system according to a fourth modification of the present invention.
도 7에 도시된 바와 같이, 상기 하우징(120)은, 상기 제1 부재(110)를 하부면으로 하여 반구 형상으로 형성된 부피제어부(126), 및 상기 부피제어부(126)와 연결되어 상기 부피제어부(126)의 상부에 변형방지부(128)를 포함하고, 상기 하우징(120)은 상기 변형방지부(128)와 연결되어 외부에서 변형방지부(128)를 관측할 수 있도록 관측창(140)이 형성될 수 있다. 여기서, 상기 부피제어부(126) 및 변형방지부(128)는 도 7에 도시된 바와 같이, 일정한 공간을 의미한다. 또한, 관측창(140)은 투명 또는 반투명의 재질로 구비될 수 있다.As shown in FIG. 7, the housing 120 is connected to the volume control unit 126 and the volume control unit 126 formed in a hemispherical shape with the first member 110 as a lower surface. The deformation preventing part 128 is disposed on the upper part of the upper part 126, and the housing 120 is connected to the deformation preventing part 128 to observe the deformation preventing part 128 from the outside. This can be formed. Here, the volume control unit 126 and the deformation prevention unit 128, as shown in Figure 7, means a constant space. In addition, the observation window 140 may be provided with a transparent or translucent material.
도 2를 참조하면, 제1 부재(110)가 유체(200)의 압력을 받아 팽창할 때, 좁은 제2 홀(124)을 통과하면서 급격하게 팽창된다. 이로 인하여, 제1 부재(110)가 소성 변형될 우려가 있고, 만일 소성 변형되면, 압력지표계(100)에서의 재사용이 불가능할 수 있다. 따라서, 제1 부재(110)의 소성변형을 방지하기 위해서, 제1 부재(110)의 급격한 팽창을 억제할 필요가 있다.Referring to FIG. 2, when the first member 110 expands under the pressure of the fluid 200, the first member 110 rapidly expands while passing through the narrow second hole 124. For this reason, the first member 110 may be plastically deformed, and if plastically deformed, reuse of the pressure indicator system 100 may not be possible. Therefore, in order to prevent plastic deformation of the first member 110, it is necessary to suppress the sudden expansion of the first member 110.
따라서, 도 7에 도시된 바와 같이, 1차적으로 제1 부재(110)의 팽창을 억제하는 부피제어부(126) 외에, 부피제어부(126)의 상부에 반구 형상의 변형방지부(128)를 구비할 수 있다.Therefore, as shown in FIG. 7, in addition to the volume control unit 126 that primarily suppresses the expansion of the first member 110, a hemispherical deformation preventing unit 128 is provided on the upper portion of the volume control unit 126. can do.
이로 인하여, 제1 부재(110)의 단계적인 팽창을 유도함으로써, 제1 부재(110)가 급격히 팽창하는 것을 방지하여, 제1 부재(110)의 소성변형의 위험을 줄일 수 있다. 또한, 팽창한 것을 관측창(140)을 통하여 관찰함으로써, 유체(200)의 압력이 소정의 압력에 도달하였는지를 파악할 수 있다. 이때, 하우징(120)의 표면 중 관측창(140)외의 부분을 불투명한 재질로 구비하면, 제1 부재(110)의 팽창 여부를 더욱 명확히 확인할 수 있다.For this reason, by inducing the stepped expansion of the first member 110, it is possible to prevent the first member 110 from expanding rapidly, it is possible to reduce the risk of plastic deformation of the first member (110). In addition, by observing the expansion through the observation window 140, it is possible to determine whether the pressure of the fluid 200 has reached a predetermined pressure. In this case, when the portion of the surface of the housing 120 other than the observation window 140 is provided with an opaque material, it is possible to more clearly check whether the first member 110 is expanded.
도 8a 내지 도 8b는 본 발명의 제5 변형예에 따른 압력지표계의 단면도이다.8A to 8B are cross-sectional views of a pressure indicator system according to a fifth modification of the present invention.
도 8a에 도시된 바와 같이, 상기 하우징(120)의 상부면은 평면이고, 상기 하우징(120)의 상부면의 내부로부터 외측으로 투명 또는 반투명의 재질의 관측창(140)이 형성될 수 있다.As shown in FIG. 8A, the upper surface of the housing 120 is flat and an observation window 140 of transparent or translucent material may be formed from the inside of the upper surface of the housing 120 to the outside.
제1 부재(110)가 팽창하면, 상술한 바와 같이, 포물선 또는 반구 형상으로 팽창한다. 따라서, 제1 부재(110)의 중심부가 하우징(120)의 중심부에 가장 먼저 접촉하게 된다. 그 후, 내부 압력이 증가할수록 제1 부재(110)는 계속적으로 팽창하는데, 하우징(120)은 관측창(140)에 의하여 밀폐되었으므로, 제1 부재(110)의 중심부는 더 이상 팽창할 수 없고, 측방향으로 팽창하게 된다. 따라서, 도 8a에 도시된 바와 같이, 외측으로 팽창부위가 점차적으로 넓어져, 제1 부재(110)가 하우징(120)의 상부면에 접촉하는 면적이 넓어진다. 따라서, 제1 부재(110)의 팽창이 진행될수록, 하우징(120)의 상부면에 접촉하는 제1 부재(110)는 하우징(120) 상부면의 내부로부터 외측으로 진행된다. When the first member 110 expands, it expands in a parabolic or hemispherical shape as described above. Therefore, the center of the first member 110 is in contact with the center of the housing 120 first. Thereafter, as the internal pressure increases, the first member 110 continuously expands, and since the housing 120 is sealed by the observation window 140, the center of the first member 110 can no longer expand. , It expands laterally. Therefore, as shown in FIG. 8A, the inflated portion gradually widens outward, thereby increasing the area where the first member 110 contacts the upper surface of the housing 120. Therefore, as the expansion of the first member 110 proceeds, the first member 110 contacting the upper surface of the housing 120 proceeds from the inside of the upper surface of the housing 120 to the outside.
따라서, 제1 부재(110)가 하우징(120)의 내면에 접촉하는 현상을 관측을 할 수 있도록, 하우징(120) 상부면의 내부로부터 외측으로 투명 또는 반투명 재질의 관측창(140)을 형성할 수 있다. 이때, 상술한 바와 같이 제1 부재(110)은 반구 또는 포물선 형태로 팽창하여, 중심부부터 팽창하므로, 하우징(120)의 중심으로부터 외측으로 투명 또는 반투명 재질의 관측창(140)을 형성할 수 있고, 명확한 대비를 위해, 관측창(140) 외의 부분을 불투명한 재질로 구성할 수 있다. 또한, 제1 부재(110)의 이러한 팽창을 더욱 명확하게 관찰할 수 있도록, 하우징(120)은 도 8a 및 도 8b에 도시된 바와 같이, 다각기둥형상으로 구비될 수 있다.Accordingly, the observation window 140 made of a transparent or translucent material may be formed from the inside of the upper surface of the housing 120 to the outside so that the phenomenon in which the first member 110 contacts the inner surface of the housing 120 can be observed. Can be. In this case, as described above, since the first member 110 expands in a hemispherical or parabolic form and expands from the center, the first member 110 may form an observation window 140 made of a transparent or translucent material from the center of the housing 120 to the outside. For clear contrast, parts other than the observation window 140 may be made of an opaque material. In addition, in order to more clearly observe such expansion of the first member 110, the housing 120 may be provided in a polygonal column shape, as shown in Figure 8a and 8b.
따라서, 유체(200)의 압력증가를 육안으로 단계별로 파악할 수 있고, 사용자는 적절한 대처를 취할 수 있다. Therefore, the pressure increase of the fluid 200 can be grasped visually step by step, and the user can take appropriate measures.
한편, 도 8b에 도시된 바와 같이, 상기 관측창(140)은 이격되어 복수 개가 내부에서 외측으로 배열되면서 형성될 수 있다. 구체적으로, 하우징(120)의 상부면의 내부로부터 외측을 향해 복수의 관측창(140)을 형성하고, 복수의 관측창(140) 사이의 이격부분을 포함한 관측창(140) 외의 부분을 불투명하게 함으로써, 앞선 실시예처럼 관측창(140)을 1개로 구성했을 때보다, 더욱 세밀화하여 구분할 수 있다. 또한, 상술한 바와 같이, 제1 부재(110)의 팽창 형상을 고려하여, 하우징(120)의 중심부터 외측으로 관측창(140)을 형성할 수 있다. 따라서, 소정의 관측창(140)에 제1 부재(110)가 접촉하는지를 육안으로 확인하여, 내부 유체(200)의 압력을 단계적으로 더욱 세분화하여 파악할 수 있다.On the other hand, as shown in Figure 8b, the observation window 140 may be formed while being spaced apart from the plurality arranged inside. Specifically, the plurality of observation windows 140 are formed from the inside of the upper surface of the housing 120 to the outside, and the portions other than the observation window 140 including the spaced portions between the plurality of observation windows 140 are opaque. By doing so, as compared with the case in which one observation window 140 is configured as in the previous embodiment, it is possible to further refine the classification. In addition, as described above, the observation window 140 may be formed from the center of the housing 120 to the outside in consideration of the expansion shape of the first member 110. Therefore, by visually checking whether the first member 110 contacts the predetermined observation window 140, the pressure of the internal fluid 200 may be further subdivided and grasped.
