Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only the embodiment of the utility model part, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
The every other embodiment obtained is put, shall fall within the protection scope of the present invention.
Embodiment
A kind of testing stand embodiment of detection gas valve provided by the utility model, as shown in Figures 1 to 5, this implementation
Example includes gas gas storage shell 1, is equipped with cover board 2 in the upper surface of gas gas storage shell 1, is equipped between cover board 2 and gas gas storage shell 1
Gasket I 10, cover board 2 are equipped with supporting mechanism 5, detection device 6, intake valve 7, air outlet valve 8, binding post 9；The support machine
5 central part of structure is fixed with cylinder 4, and the air inlet of cylinder 4 is connect with power source, is removably set on the piston rod 3 of cylinder 4
It is useful for compressing the hold-down mechanism of valve；Valve detection mouth is offered on the cover board 2, valve detection mouth is equipped with gasket
II 11, valve detection mouth are corresponding with hold-down mechanism；Detection device 6 is pressure gauge, and power source is air compressor, in addition to inciting somebody to action
Pressure gauge is as judging that valve whether outside the detection device of gas leakage, can also select other detection devices, but pressure gauge performance
Stablize, is easy to be commercially available and at low cost, the selection of power source is identical as the selection of detection device, in addition to air compresses
Outside machine, it is also an option that other.In practice, detected material is put into from valve detection mouth to detection by testing staff,
By observe pressure gauge can judge detected material whether gas leakage.
In order to make those skilled in the art be better understood from the utility model, now hold-down mechanism in the present embodiment is limited
Fixed description, hold-down mechanism includes connector 31, and one end of connector 31 is connect with piston rod 3, and the other end of connector 31 is equipped with
Horizontal support mechanism 32, is arranged with pressure rack 33 straight down in horizontal support mechanism 32,33 bottom end of each pressure rack with for pressing
The pressing plate 34 of tight valve connects.Connector 31 is threadedly coupled with piston rod 3, compared with other connection types, using threaded connection
It is easily installed personnel's installation and the maintenance of maintenance personal.
In order to improve the present embodiment, horizontal support mechanism 32 is welded on the other end of connector 31, and pressure rack 33 is welded on horizontal branch
On support mechanism 32, the bottom end of each pressure rack 33 is welded with pressing plate 34.Hold-down mechanism volume is little, will be connected by welding manner
First 31, horizontal support mechanism 32, pressure rack 33 and pressing plate 34 are welded as a whole, and do not influence to transport, but installation personnel is facilitated to install, with
And maintenance personal repairs it.
The valve detection mouth is semicircle valve detection mouth, the shape and valve of the horizontal support mechanism 32 and pressing plate 34
The shape of detection mouth is identical.
In order to make the public and those skilled in the art be better understood from the utility model, so it is preferably that this practicality is new
Type is promoted the use of, and first Fig. 3, Fig. 4 and Fig. 5 is combined to describe the operating procedure of the utility model, Details as Follows：
Detected material is put into valve detection mouth first, detected material includes valve 12, and the electricity of the public is cooperateed with valve 12
After then putting gasket II 11, hold-down mechanism is transported downwards by cylinder 4 for machine and propulsion device 121 and gasket 123
Dynamic, pressing plate 34 compresses the edge outlet point of valve 12, while motor and propulsion device promotion gasket 123 are moved upwards and held out against
Then intake valve 7 is opened in valve gas outlet 122, close air outlet valve 8, will reach a level pressure in gas gas storage shell 1 and valve 12
Power finally closes intake valve 7, and whether observation pressure gauge has pressure release situation.
If there is pressure gauge pressure release, illustrate detected material gas leakage, if pressure gauge does not have pressure release, illustrates that detected material does not leak
Gas.
At this moment air outlet valve 8 is opened, is 0 by the gas pressure pressure release in gas gas storage shell 1 and valve 12, then motor and pushes away
It moves downward into device collapsed seal pad 123 and is isolated with valve gas outlet, last cylinder 4 and pressure rack 33 are upward, and detected material can
To take away.
Existing detection scheme be by detected material into the water, by observe bubble judge valve 12 whether gas leakage, work as leakage
When gas, water enters detected material, and the relative electronic components short circuit such as motor being easy to cause in detected material is scrapped.The prior art
In addition to drawbacks described above；The utility model is other than overcoming drawbacks described above, and when pressure gauge pressure release, testing staff can stop operation, right
It needs the place sealed to re-operate, investigation the reason of leading to pressure gauge pressure release, is repeated above-mentioned steps and is detected, this is carried
High detection valve whether the accuracy of gas leakage.
In order to meet succinct requirement, what each some importance of this specification illustrated be it is different from other parts it
Locate, identical similar portion can cross-reference between various pieces.The foregoing description of the disclosed embodiments keeps this field professional
Technical staff can realize or use the utility model.
