Electric control valve installation principle:
1. The installation position, height, and direction of inlet and outlet of the valve must meet the requirements of the direction design, and the connection should be firm and tight.
2. The valve can be connected to the pipeline with various forms of ends. The most important connection methods are threaded, flanged and welded connections. When the flange is connected, if the temperature exceeds 350 degree , it will be damaged by the bolts. Flange and gasket creep relaxation, high temperature resistant bolt material should be selected.
3. Visual inspection must be carried out before the valve is installed, and the nameplate of the valve should comply with the current international standard GB12220 "General Valve Mark". For the valve whose working pressure is greater than 1.0MPA and plays a role in cutting off the main pipe, the strength and tightness test shall be carried out, and it shall be used only after passing the test. Other valves may not be tested separately and will be tested in the system pressure test.
4. During the strength test, the test pressure is 1.5 times the nominal pressure, the duration is not less than 5min, and the valve shell and packing should be free of leakage.
5. During the tightness test, the test pressure is 0.3mpa, and the test pressure should remain unchanged for the duration of the test, and the time should comply with the provisions in Table 2. The valve disc sealing surface is qualified if there is no leakage.
6. Nominal diameter: DN15-500
