Draft tube is driven to be tightly connected by flange plate and valve inlet to be checked by thrust unit, and make draft tube, escape pipe is communicated with the valve pocket of valve to be checked, therefore placement stable on testing jig valve to be checked can be made, when detection leaks outside, open valve to be checked and gas admittance valve, close air outlet valve, by air pump toward draft tube and escape pipe and valve interacvity air-filling, close gas admittance valve afterwards, whether changed by principal pressure table and secondary stress table and can judge whether valve to be checked leaks outside, if leak outside, then close valve to be checked, if principal pressure gauge pressure diminishes and secondary stress gauge pressure is constant, then can judge that valve inlet side to be checked leaks outside, in like manner or valve export side to be checked leak outside, when leaking in detection, close air outlet valve and valve to be checked, open gas admittance valve and inflate, closing gas admittance valve afterwards, whether changed by secondary stress gauge pressure and can judge the whether interior leakage of valve to be checked.
As preferably, described thrust unit is cylinder, and described draft tube is connected with the piston rod of cylinder.
Also other existing thrust units can be adopted.
As preferably, described flange plate is also provided with O-ring seal, and described O-ring seal can offset with valve inlet to be checked and seal.
Better tightness is made by O-ring seal.
As preferably, also comprise tank, described testing jig entirety is placed in tank.
By whether occurring in tank whether bubble can leak outside in intuitive judgment.
As preferably, described holder is threaded with valve export to be checked.
Compared with prior art, the utility model tool has the following advantages:
Draft tube is driven to be tightly connected by flange plate and valve inlet to be checked by thrust unit, and make draft tube, escape pipe is communicated with the valve pocket of valve to be checked, therefore placement stable on testing jig valve to be checked can be made, when detection leaks outside, open valve to be checked and gas admittance valve, close air outlet valve, by air pump toward draft tube and escape pipe and valve interacvity air-filling, close gas admittance valve afterwards, whether changed by principal pressure table and secondary stress table and can judge whether valve to be checked leaks outside, if leak outside, then close valve to be checked, if principal pressure gauge pressure diminishes and secondary stress gauge pressure is constant, then can judge that valve inlet side to be checked leaks outside, in like manner or valve export side to be checked leak outside, when leaking in detection, close air outlet valve and valve to be checked, open gas admittance valve and inflate, closing gas admittance valve afterwards, whether changed by secondary stress gauge pressure and can judge the whether interior leakage of valve to be checked.
