6.1 Test items
6.1.1 Strength test
The pressure-bearing parts on the manifold shall be subjected to hydraulic strength test one by one. Test pressure value: When the maximum working pressure is 21 and 35MPa, the strength test pressure value is 42 and 70MPa respectively; when the maximum working pressure is 70MPa, the strength test pressure value is 105MPa. 6.1.2 Sealing test
The whole machine and gate valve shall be subjected to sealing test before assembly. Test pressure value: equal to the maximum working pressure: 6.1.3 Low-pressure sealing test
The gate valve shall be subjected to low-pressure sealing test, and the test pressure is 0.7MPa. 6.2 Pressure test requirements
6.2.1 Test medium: clean water.
6.2.2 The main force of the test is increased step by step according to 7MP×n, and the pressure rises to the test pressure value. The stabilization time is not less than 3min, where n is 1, 2, 3. 4......
Depressurize to zero, and then increase the pressure step by step to the test pressure value: the stabilization time is not less than 3min. 6.2.3 The air in the cavity should be removed before the pressure test. The test medium should be completely discharged after the pressure test. 6,2,4 No leakage during the stabilization period is qualified.
When the gate valve is tested for tightness and low claw tightness. The sealing surface between the gate and the valve seat should not be coated with any grease. 6.3 Inspection rules
