Abstract
The invention discloses a liquid level switch, which can be exchanged without discharging liquid. The liquid level switch comprises a base and a bracket which is similar to C in shape and arranged on the base, wherein a plurality of photoelectric detector switches arrayed in a row are arranged on one side of the bracket; a slider is arranged between two projections of the bracket in a sliding manner; the slider can be detected by the photoelectric detector switch at corresponding position when sliding up and down; a connecting rod is fixedly arranged on the slider; and one end of the connecting rod is provided with a floater which is positioned below the base. The liquid level switch is suitable to be used on occasions when the liquid level in a container is to be detected or controlled.
Description
Technical field
The present invention relates to a kind of liquid level control device, relate in particular to a kind of liquid-level switch.
Background technology
Liquid-level switch is a kind of common liquid level detection device in the Level Detection field.Wherein, the tongue tube floating-ball level switch is a kind of the most frequently used liquid-level switch, it comprises: fall L shaped non-magnetic pipe, be provided with tongue tube in the non-magnetic pipe, one end of tongue tube links to each other with holding wire, be arranged with an inside on the non-magnetic pipe and be provided with the ball float of magnet ring, also be provided with upper limit catch and lower limit catch on the non-magnetic pipe, ball float is between upper limit catch and lower limit catch.The tongue tube Floating Ball Liquid Level operation principle of said structure is: the tongue tube floating-ball level switch is installed on the container side wall, the rising of the interior liquid level of container or decline can drive ball float and move up and down, when liquid level is lower than lower limit catch on the non-magnetic pipe, ball float contacts with the lower limit catch, the interior tongue tube of non-magnetic pipe this moment produces the action of adhesive (disconnection), and export to one in external control device by holding wire and open (pass) signal, when liquid level is higher than the upper limit catch, ball float rises and contacts with the upper limit catch, and the interior tongue tube of non-magnetic pipe this moment produces the action of disconnection (adhesive) and exports to a pass of external control device (opening) signal by holding wire.Because whole tongue tube floating-ball level switch all is immersed in the liquid, so when work long hours back or lost efficacy when needing to change of this liquid-level switch, could change after must the liquid in the container all discharging, ten minutes bothers.
Summary of the invention
Technical problem to be solved by this invention is: will provide a kind of drain that need not with regard to removable liquid-level switch.
For addressing the above problem, the technical solution used in the present invention is: a kind of liquid-level switch, comprise base and the support that is similar to C shape that is arranged on the base, one side of support is provided with several photoelectric detection switch in one line, the rocker piece that slides and be provided with between two projections of support can be detected by the photoelectric detection switch of relevant position when rocker piece slides up and down, and is set with connecting rod on the rocker piece, one end of connecting rod is provided with ball float, and ball float is positioned at the base below.
Described support is provided with waist-shaped hole, and photoelectric detection switch is fixed in the waist-shaped hole by the nut on the photoelectric detection switch;
Pass through screw between described rocker piece and the connecting rod;
Described rocker piece both sides are respectively arranged with the chute that matches with two projections on the support.
The invention has the beneficial effects as follows: adopted outside installing type photoelectric detection switch, made when changing liquid-level switch, also liquid to be drained the not direct contact liq of liquid level detection device.
Description of drawings
Fig. 1 is the structural representation of liquid-level switch of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1, base, 2, support, 3, photoelectric detection switch, 4, waist-shaped hole, 5, rocker piece, 6, connecting rod, 7, ball float, 8, projection, 9, chute, 10, screw.
Embodiment
Below in conjunction with accompanying drawing, liquid-level switch of the present invention and structure are described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of liquid-level switch, comprise base 1 and the support that is similar to C shape 2 that is arranged on the base 1, on one side of described support 2 waist-shaped hole 4 is set, photoelectric detection switch 3 is fixed in the waist-shaped hole 4 by the nut of its afterbody, conveniently regulate the distance between each photoelectric detection switch 3, can satisfy the demand of multiple detection liquid level.The concrete quantity of photoelectric detection switch can be set according to actual needs.Slide between two projections 8 of the opposite side of support 2 and be provided with rocker piece 5, rocker piece 5 both sides are respectively arranged with the chute 9 that matches with two projections 8, two projections 8 are inserted respectively in two chutes 9, rocker piece 5 just can slide up and down along support 2, be fixed with connecting rod 6 by screw 10 on the rocker piece 5, by the relative position of screw 10 scalable rocker pieces 5 on connecting rod 6, an end of connecting rod 6 is provided with ball float 7, and ball float 7 is positioned at base 1 below.
Operation principle of the present invention is: the base 1 of liquid-level switch of the present invention is fixed on the container, 3 of photoelectric detection switch insert in the electrical equipment control loop, rising or decline along with liquid in container, ball float 7 also rises thereupon or descends, and ball float 7 drives rocker piece 5 by connecting rod 6 and rises or descend, when in the process that rocker piece 5 is rising or descending during through the photoelectric detection switch 3 of relevant position, photoelectric detection switch 3 detects rocker piece 5, the just corresponding signal of outside electrical equipment control loop of giving, control outside electrical equipment simultaneously and carry out a corresponding action, promptly the liquid in the container is carried out supply, take away or quit work.
Advantage of the present invention is: adopted outside installing type photoelectric detection switch, so that liquid level detection device critical piece contact liq not, this has just reduced the corrosion of liquid to checkout gear, significantly prolonged the service life of liquid-level switch, and when changing liquid-level switch, also liquid need not be drained, only need to pull down behind the base on the container getting final product that whole liquid-level switch is withdrawn and more renewed.
Claims (4)
1. liquid-level switch, comprise base and the support that is similar to C shape that is arranged on the base, it is characterized in that: a side of described support is provided with several photoelectric detection switch in one line, the rocker piece that slides and be provided with between two projections of support, when sliding up and down, rocker piece can be detected by the photoelectric detection switch of relevant position, be set with connecting rod on the rocker piece, an end of connecting rod is provided with ball float, and ball float is positioned at the base below.
