Description
Technical field
The present invention relates to air tightness detection apparatus technical field, especially a kind of pressure water air tightness tester.
Background technique
Air-leakage test is that compressed air (or ammonia, freon, helium, halogen gas etc.) is pressed into container, using in container
The test method(s) that the pressure difference of outer gas checks for leaks.Air tight test need to use air-leakage detector, it is to be specifically applied to
To the device of being sealed property of cavity engineering goods detection, it is mainly used for automobile engine, gearbox, vehicle bridge, water tank, fuel tank etc.
Have in the production of seal request to cavity, the principle of air tight test is first to allow device and additional liquid (referring generally to water), structure
At closed entirety, change this whole temperature, lead to the variation of pressure, to judge air-tightness quality, not due to device
Together, the method for inspection is also different.
Currently, the method for water tank air tightness test generally passes through the Inlet and outlet water directly in cabinet, but the test side
Method needs the process for adding water and discharging water, and not only the operating time was long, but also wasted water, and detection efficiency is low.
Summary of the invention
In order to overcome the shortcomings of existing direct Inlet and outlet water low efficiency, the present invention provides a kind of pressure water air seal test dresses
It sets, carries out airtight test by adding airtight space, time saving water-saving is high-efficient.
The technical solution adopted by the present invention to solve the technical problems is: a kind of pressure water air tightness tester, including inside
It is provided with the water storage container of sealing space and test piece, water storage container is the cavity for being marked with water, has been horizontally set with inside water storage container
For fixing the support plate of test piece, the cavity of two sides is to be connected to support plate up and down, and support plate is arranged in sealing space
Lower section, sealing space top are provided with the air inlet and air outlet for adjusting air pressure inside, and the setting of sealing space bottom is useful
In the water outlet of draining, test piece setting is square on the supporting plate, and is fixedly connected by compressing member with support plate.
Further, it is separately positioned on the top two sides of sealing space including air inlet and air outlet, and passes through delivery pipe
Road is connected to the external of water storage container.
Further, including there are two water outlet settings, and it is provided with the two sides of the bottom of sealing space respectively, it can be faster
Water is discharged.
Further, parallel with the bottom plate of water storage container including offering the bottom surface of the sealing space of water outlet, to prevent
Only water outlet is intake.
It further, is the pressure zone that test piece both ends are set, pressure zone and test piece appearance face paste including compressing member
It closes, test piece can be stablized bundle and set on the supporting plate.
It further, is the water tank of bottom belt stabilizer blade including water storage container.
The invention has the advantages that carrying out watertight test to test piece by the water tank with sealing space, only need
Air inlet and outlet can drive water level raising and lowering in cabinet in sealing space, move in circles, time saving water-saving, detection efficiency
It is high.

Specific embodiment
A kind of pressure water air tightness tester, the water storage container 3 including being internally provided with sealing space 1 and test piece 2, storage
Water container 3 is the cavity for being marked with water, is horizontally set with the support plate 4 for fixing test piece 2 inside water storage container 3, in support plate 4
The cavity of lower two sides is connection, and sealing space 1 is arranged in the lower section of support plate 4, is provided at the top of sealing space 1 for adjusting
The air inlet 5 of air pressure inside and gas outlet 6,1 bottom of sealing space are provided with the water outlet 7 for draining, and test piece 2 is arranged
It is fixedly connected above support plate 4, and through compressing member 8 with support plate 4, air inlet 5 and gas outlet 6 are separately positioned on sealing sky
Between 1 top two sides, and be connected to by the external of conveyance conduit and water storage container 3, there are two water outlet 7 is arranged, and opened respectively
The two sides of the bottom of sealing space 1 are located at, the bottom plate of the bottom surface and water storage container 3 that offer the sealing space 1 of water outlet 7 is flat
Row, compressing member 8 is the pressure zone that 2 both ends of test piece are arranged in, and pressure zone is bonded with 2 outer surface of test piece, and water storage container 3 is bottom
Water tank of the portion with stabilizer blade.When installing and using, sealing space 1 is welded in 3 bottom of water storage container first, so that sealing space 1
Lower surface is parallel with the bottom surface of water storage container 3, and 1 top side of sealing space is provided with air inlet 5, and the other side is provided with gas outlet
6, air inlet 5 and gas outlet 6 are connected to by seal nipple with sealing space 1 and conveyance conduit, for separating 2 He of test piece
4 transverse weld of support plate of sealing space 1 is fixed on 3 inner wall of water storage container, and test piece 2 is by being bundled in the pressure zone at its both ends
It is fixed in support plate 4, in sealing space 1 after discharge gas, test piece 2 can be just exposed outside test water, convenient for more
The test piece 2 in support plate 4 is changed, in sealing space 1 after injection gas, the test water in water storage container 3 can just will be tested
In workpiece 2 is submerged in, when testing water submerged test piece 2, because of the effect of pressure zone, test piece 2 will not float, thus into
Promoting the circulation of qi density test, the test water in water storage container 3 is can be recycled, need to only change air pressure in sealing space 1, convenient fast
Victory, testing efficiency are high.
As shown in Figure 1, when gas outlet 6 is in the open state, when air inlet 5 is in close state, under the action of pressure,
Water in water tank enters sealing space 1 by 1 bottom water outlet 7 of sealing space, reduces water level in water storage container 3, lower than peace
The support plate 4 of test piece 2 is filled, convenient for bundling or replacing test piece 2.
As shown in Fig. 2, when gas outlet 6 is in close state, water when air inlet 5 is in the open state, in sealing space 1
Pressure by compressed air makes water level promoting in water tank by the discharge of water outlet 7, can will survey when water level reaches requirement height
When trial work part 2 floods completely, air inlet 5 is closed, so that it may carry out airtight test.After being completed, gas outlet 6, water level are opened
Decline unclamps pressure zone and takes out workpiece, the workpiece more renewed.
