Test " enter torsional moment test interface, input test pressure is 0.6MPa, clicks " RUN ", starts to test.Finally, observation experiment and
Trial curve records valve state and trial curve, and records corresponding torque after the completion.
The embodiment using the Plastic valve test device carry out Plastic valve sealing and torsional moment test, control compared with
The relatively high and stable property of precision of low test pressure is preferable, adjusts that air pressure and control reverse speed are simple, measure compared with low temperature or higher
Stop intensity under temperature is easy, and can accurately detect the torsional performance under Plastic valve high/low temperature circulatory condition, assembly and sealing valve
Door end it is easy to operate, it is quick and be less likely to occur to leak, can realize that loading sample once is continuously finished the test of all properties
Journey.
