Common four-way valve helium leak detector only has the helium leak check function at present, can't accomplish all-round property testing simultaneously, needs two procedures could accomplish four-way valve combination property and the detection that leaks outside.Though this method of testing can be accomplished the purpose of quality control, there is the shortcoming that efficient is low, cost is high, operating personnel's demand is many, be necessary to improve.
Summary of the invention:
The purpose of the present invention's exploitation is the weak point that exists to prior art and a kind of four-way valve helium leak detector with all-round property testing function is provided; It not only can accomplish helium leak check, and can accomplish the test of high pressure commutation and low pressure commutation ability.
For realizing above-mentioned purpose; Four-way valve helium leak detector with all-round property testing function of the present invention; Establish the test casing of frock in including; The test casing links to each other with helium inspection impermeability pipe system; Said test casing also is connected with commutation ability test pipe system, and described commutation ability test pipe system and helium inspection impermeability pipe system constitute parallel-connection structure.
Preferred as technique scheme, described helium inspection impermeability pipe system are tested pipe system with commutation ability and switch through switch valve.
Preferred as technique scheme, switch valve can be solenoid valve.
Preferred as technique scheme, switch valve also can be hand valve.
Preferred as technique scheme, described commutation ability test pipe system is made up of the high pressure commutation pipe system, the low pressure commutation pipe system that are connected in parallel.
Beneficial effect of the present invention is: owing to increased commutation ability test pipe system; Make helium leak detector not only can be used for helium leak check; And can be used for the test of four-way valve combination property; Thereby improved work efficiency effectively, reduced testing cost, reduced the demand to operating personnel's quantity, practicality is very strong.
