Electromagnetic stainless steel test standard related parameters
Electromagnetic stainless steel test standards apply to gate valves, globe valves, check valves, plug valves, ball valves, butterfly valves, diaphragm valves, etc.
1. The pressure test refers to the time pressure that the valve chamber should withstand during the test. The pressure test is performed on the entire valve housing formed by the connection of electromagnetic stainless steel valve cover and the like. The purpose is to test the sealing and pressure resistance of electromagnetic stainless steel and valve cover.
2. Terms introduced:
Seal test, upper seal test, test duration, test purpose, test requirements, test methods and procedures,
Evaluation indicators.
(1) The seal test refers to the test of the sealing performance of open and closed parts and electromagnetic stainless steel seals.
(2) The upper seal test refers to the test that tests the sealing performance of the valve stem and the valve cover.
(3) Test duration refers to the duration of the test under test pressure.
(4) Experimental purpose: The items of pressure test include shell test, upper seal test (the test of electromagnetic stainless steel door hard seat with sealed structure) and test seal performance.
