What are the key points of the construction equipment of the gas regulating valve? Origin of the regulating valve manufacturer: Date: 2015-4-68:22:011. The equipment orientation, height and import and export direction of the gas regulating valve must meet the requirements of the port direction planning, and the connection should be strong and tight.
The valve of the gas regulator valve may be coupled to the pipeline with various types of ends. Thread, flange and welding connection are the primary connection methods. When flange connection, if the temperature exceeds 350 ℃, due to the creep relaxation of bolts, flanges and gaskets, high temperature resistant bolt materials should be selected.
It is necessary to check the appearance of the valve of the gas control valve before the equipment, and the nameplate of the valve should conform to the rules of the current national standard GB12220 "General Valve Mark. Regarding the valves with working pressure greater than 1.0MPa and blocking effect on the backbone pipe, strength and tightness tests shall be carried out, and the valves shall be allowed to be used only after they are qualified. Other valves may not be tested independently and shall be inspected in the system pressure test.
When the strength test is carried out for the gas regulating valve, the test pressure shall be 1.5 times of the nominal pressure, and the duration shall be no less than 5min. The shell and packing of the valve shall be free of leakage. Tightness test, the test pressure is 1.1 times the nominal pressure; test pressure in the test for the duration of the moment should adhere to the same, the time should be consistent with the rules, to the valve sealing surface without leakage as qualified. Nominal diameter:
