Key points of gate valve installation:

Visual inspection must be carried out before the installation of the valve, and the nameplate of the valve shall comply with the provisions of the current national standard "general valve mark" gb12220. For the valve whose working pressure is greater than 1.0MPa and plays a role of cutting off on the main pipe, the strength and tightness performance test shall be carried out before installation, and the valve can only be used after it is qualified. During the strength test, the test pressure shall be 1.5 times of the nominal pressure, and the duration shall not be less than 5min. The valve shell and packing shall be qualified if there is no leakage. During the tightness test, the test pressure is 1.1 times of the nominal pressure; the duration of the test pressure shall meet the requirements of GB50243 standard, and it is qualified if there is no leakage on the sealing surface of the valve disc.
