3), the valve before installation must carry out a visual inspection, the valve plate should be consistent with existing national standards, "universal valve logo" GB 12220 requirements. For the work pressure is greater than 1 MPa and in the main pipe to play the role of cut off valve, the installation should be carried out before the strength and tightness test, qualified before use. Strength test, the test pressure for the nominal pressure of 1.5 times the duration of not less than 5min, the valve housing, packing should be no leakage for qualified. Tightness test, the test pressure is 1.1 times the nominal pressure; test pressure in the duration of the test should meet the requirements of the GB 50243 standard, with no leakage in the valve sealing surface as qualified.
4), handwheel, handle and drive mechanism for lifting are not allowed to use, no collision.
5), with the transmission of the gate valve, according to the provisions of the provisions of the use of product installation.
