Description
Technical field
The present invention relates to fluid experiment equipment, relate to the device of quantitative aerating in a kind of fluid experiment.
Background technology
Gas flow standard device is to take air as medium, adopts negative pressure method, is mainly applicable to calibrating, standard, the type evaluation work of the gas meters such as speed mode, positive displacement, differential pressure type and mass flowmeter, also can be for the mensuration of gas flow.Gas flow standard device is divided into primary standard device and Transfer Standards device, and primary standard device is highest standard, and primary standard device is divided into volumetric method and mass method two classes, can be called dynamic method and static method again.As PVTt(pressure, volume, temperature, time in volumetric method) owned by France in Static Volumetric Method device, bell-jar, gas volume pipe, soap film type etc. belong to dynamic volumetric method device, and wherein, bell-jar also can be used for Static Volumetric Method; Quality time in mass method, (Mt) was owned by France in Static mass method.Critical flow venturi standard is widely adopted as gas flow Transfer Standards, U.S. southwest rock gas research institute, and Britain national engineering laboratory etc. all adopts this class standard.Germany physical technique research institute adopts check industrial gas and other gas flows of nozzle in parallel.
Due to fugacity and the compressibility of gas, make in laboratory the mensuration of gas volume more complicated than liquid.Stereometry generally adopts the direct method of measurement and the indirect method of measurement, and the direct method of measurement is the method that adopts gas meter to detect, and the indirect method of measurement is by the physical dimension indirect determination flow value between sensor, to determine the size of volume.
In addition, traditional gas input device adopts injecting type or two kinds of modes of nozzle-type, mainly contains three shortcomings.The one, gas impermeability deficiency causes measuring error, and as normal injection formula formula aerating equipment, due to the bubble-tight problem of piston, gas is easily revealed from edge; The employing volume calibrating installation that in the 2nd, above 2, mode needs is calibrated, and cost is higher; The 3rd, if when the testing equipment of injecting gas has higher interior pressure, employing Manual pressurizing will be very difficult.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, proposed the device of quantitative aerating in a kind of fluid experiment.
The quantitative aerator of fluid experiment waterpower, comprises the first container, is fixed on sealing graduated cylinder in described the first container and second container that can lifting;

The bottom of described sealing graduated cylinder is with the osculum being communicated with the first container, and the top of sealing graduated cylinder is provided with air induction conduit and adds airway.
Fluid media (medium) used in the present invention can be selected as required, if when the gas that band injects is water insoluble, can adopt common distilled water, if water-soluble, survey can adopt other fluid media (medium)s, as phenixin etc.The bottom of sealing graduated cylinder can be one or more with the osculum being communicated with the first container.Adding airway is connected with needing the experimental facilities of aerating.The air induction conduit gas that experimental facilities need to add is as required selected, and if desired adds air directly unsettled (being communicated with atmosphere), also can be connected with gas cylinder as required.
The quantitative aerator of fluid experiment waterpower of the present invention, by moving up and down second container, make to produce hydraulic pressure difference between the first container and second container, under hydraulic action, accuracy controlling enters the volume of air of experimental facilities, do not need the extra pressurized equipment arranging, cost is low, and the good airproof performance of fluid media (medium), otherwise gas overflowing, reduces to cause measuring error because of impermeability deficiency.
Described the first container and second container are the open-top receptacle of open-top.The first container and second container are the open design of open-top, and the two is all communicated with atmosphere, thereby have avoided the injecting gas cubing causing because the pressure between the first container and second container is inconsistent to be forbidden.
Described the first container and sealing graduated cylinder are transparent material, and sidewall is all with scale.By scale, facilitate the volume of observing and regulating input gas, the minimum scale on the first container and sealing graduated cylinder sidewall has reacted the quantitative precision of this gas volume, therefore as required, can select different scales.
Described air induction conduit, add on airway and flexible conduit and be respectively equipped with valve.By valve close and open cooperation, complete aerating, specific as follows: first to close the valve that adds airway, open the valve of air induction conduit and flexible conduit, move down second container, water level in graduated cylinder is declined, suck the ambient atmos of certain volume.Then close the valve of air induction conduit, open the valve that adds airway, the second container that moves up, completes aerating.
Regulate for convenience the height of second container, carry out gasometry, the quantitative aerator of described fluid experiment waterpower is also provided with for driving the crane of second container.
Described crane comprises:
The lifting column of vertically-arranged, the bottom of described lifting column is provided with base;
With the tripod that described lifting column is slidably matched, described second container is placed on this tripod;
With the lifting runner that described lifting column is rotatably assorted, between described lifting runner and tripod, be provided with the driving member cooperatively interacting.
Described lifting column is provided with the guide rail of vertical layout, and described tripod is provided with the sliding shoe matching with this guide rail.
Described driving member comprises:
With the co-axially fixed gear of lifting runner;
Be fixed on tripod, and the tooth bar being meshed with described gear.
On lifting runner, be coaxially fixed with ratchet, on described lifting column, be hinged with the location ratchet matching with described ratchet.This device is mainly its positioning action, when stopping operating lifting runner, guarantees that tripod can not glide, and also available other locating devices substitute.
By rotating lifting runner, by gearing, drive tripod on guide rail, rise or decline, realize the height adjusting function of second container.After second container height reaches required height, the lifting runner that stops operating, now by the effect of ratchet and ratchet, makes second container be fixed on this position.
The quantitative aerator of described fluid experiment waterpower is also provided with cushion cap, and described the first container is placed in the end face of cushion cap.Make the first container there is certain height, facilitate the hydraulic pressure difference of the first container and second container to regulate.
When the present invention uses, first close gas-adding pipe valve, open draft tube valve, move down the flexible pipe other end with the container of handle, water level in graduated cylinder is declined, suck outside air.Subsequently, close draft tube valve, open gas-adding pipe valve, the container moving up on lifting column, under Water Pressure, accuracy controlling enters the volume of air of experimental facilities, after definite input gas volume, closes connection valve.This device not only can very accurately be measured the volume of air needing, and in aerating process, adjusted volume is big or small arbitrarily.
The quantitative aerator of fluid experiment waterpower of the present invention is compared with pot type piston formula aerating equipment, has utilized watertightness, stops gas to be revealed from edge.Change the container height on lifting column simultaneously, by pressure reduction head, to the experimental facilities gas transmission that contains interior pressure, avoided the difficulty of Manual pressurizing, stability and operability improve greatly.
