About the fixed value checking of safety valve 20 and the summary of leakage test:
For the fixed value checking of safety valve 20, by operation pressure regulator valve 11 to adjust the input terminal for being input to safety valve 20
Air pressure size, one end that observation conducting element 15 extends into liquid container 16 are generating bubble and are not generating two kinds of phenomenons of bubble
Between pressing force threshold point, so that the practical setting valve of safety valve 20 is detected, thus by the practical setting valve and theoretical parameter
Value is compared, and achievees the purpose that verification.
For the leakage test of safety valve 20, the air pressure of the input terminal of safety valve 20 will enter by operation pressure regulator valve 11
Then big minor adjustment closes the input terminal of connector 14, so that safety valve 20 is defeated to preset test value by isolating valve 12
The air pressure for entering end maintains preset value, within the preset time (such as pressure maintaining 2min), passes through the gas in observation liquid container 16
The variation of situation and pressure gauge 13 is steeped, the leakproofness of safety valve 20 is examined.
Above-mentioned safety valve fixed value checking and seal test device 100, in use, the input terminal of air source distributor is connected gas
Then source or gas source interface are shunted air-flow by the air source distributor to distribute to multiple test units 10 and use.
For test unit 10, it is equipped with the pressure regulator valve 11 for adjusting the air-flow size for being input to safety valve 20, for observing in real time
The pressure gauge 13 of the air pressure size of the input terminal of safety valve 20 seals examination for realizing the air-flow pressure maintaining to safety valve 20 to realize
The isolating valve 12 tested and the liquid container 16 for liquid needed for holding test.When need to safety valve 20 carry out definite value
When verification, isolating valve 12 is opened, so that being tended to remain between pressure regulator valve 11 and connector 14, is then adjusted by operation
Pressure valve 11 reaches the mesh of 20 fixed value checking of safety valve by bubble situation in observation liquid container 16 to adjust the air pressure of air-flow
's.When needing to be sealed test to safety valve 20, adjusted by pressure regulator valve 11 to preset air pressure, then by isolating valve 12
It closes, so that pressure regulator valve 11 and connector 14 is separated, so that the input terminal of safety valve 20 is maintained at preset air pressure environment
To realize the purpose of 20 leakage test of safety valve.Above-mentioned design carries out distribution of air flow by air source distributor, and by simple
Device build the test unit 10 for 20 fixed value checking of safety valve and leakage test, take into account testing equipment use just
Benefit and it is low in cost under the premise of, in the case where realizing limited gas source connector, safety valve is carried out simultaneously to multiple safety valves 20
20 fixed value checkings and leakage test.In addition, the safety valve fixed value checking and seal test device 100 are not only easily assembled, but also
It carries very convenient, for occupying little space for test site, can quickly be assembled according to the number of test.
Supplementary explanation, safety valve fixed value checking and seal test device 100 can not only apply to the skill of safety valve
Art examination or technology contest, the safety valve that can also apply in actual production are examined.
Each technical characteristic of above embodiments can be combined arbitrarily, for simplicity of description, not to above-described embodiment
In each technical characteristic it is all possible combination be all described, as long as however, the combination of these technical characteristics be not present lance
Shield all should be considered as described in this specification.
Above embodiments only express the preferred embodiment of the utility model, and the description thereof is more specific and detailed, but
It cannot be understood as the limitations to utility model patent range.It should be pointed out that for the ordinary skill of this field
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this
The protection scope of utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
