为了保证我厂生产的九种规格新型柱塞阀使用安全和无泄漏性能,产品出厂前必须在试验台上经过耐压性和密封性试验。试压台来不及更换,我们采用一种简易试压夹具代替试压台,该夹具结构简单,使用方便、可靠,成本低,设计、制造周期 In order to ensure the safety and leak-proof performance of the nine new plunger valves manufactured by our factory, the products must be tested for pressure resistance and tightness before leaving the factory. Pressure test bench too late to replace, we use a simple pressure fixture instead of pressure test fixture, the fixture structure is simple, easy to use, reliable, low cost, design, manufacturing cycle
