Construction and installation points 1. Valve mounting position, height, and export orientation must meet the design requirements, the connection should be firmly tight. 2. The valve means of various forms of end portion connected to the pipe line. The most important connections are threaded, flanged and welded connections. When the flange connection, stainless steel damper effect if the temperature exceeds 350 ℃, due to the bolts, flanges and gaskets creep relaxation, you should choose high temperature bolt material. 3. The valve must be visually inspected prior to installation, the valve plate should be consistent with existing national standards GB12220 "Universal Valve logo" requirement. For working pressure greater than 1.0MPa and the role played off valves on the main pipe, should be the strength and tightness test, passing behind the prospective use. Other valves may not be tested separately, stay in the inspection system pressure test. 4. strength test, the test pressure is 1.5 times the nominal duration of not less than 5min, the valve housing, packing should be no leakage. 5. Tightness test, the test pressure of 1.1 times the nominal; test pressure in the test duration should remain unchanged, the time should meet the requirements of Table 2, the valve sealing surface without leakage is qualified.
