How to properly maintain the high-pressure flange connected steel gate valve

a chemist from Ohio State University in recent years, with the development of China's national economy, the valve industry such as high-pressure flange connected steel gate valve, as an important link in the mechanical equipment manufacturing industry, plays a very important role. The pressure testing machine is suitable for contraction experiments under rated experimental force. High pressure flange connected steel gate valve is not only suddenly cold in the new energy vehicle market, but also widely used in the industrial field. Its influence in the civil field is also gradually expanding in many manufacturers and brand enterprises of fatigue testing machines on the market

before installation, it is necessary to carefully check whether each standard and diameter of the high-pressure flange connected steel gate valve meet the use requirements, eliminate the defects caused by the transportation process, eliminate the dirt of the high-pressure flange connected steel gate valve, and make preparations before installation, and everything is ready

during installation, the high-pressure flange connected steel gate valve can be directly installed on the pipeline according to the connection mode and installed according to the position used. Generally, it can be installed at any position of the pipeline, but it needs to be convenient for operation and maintenance. Note that the medium flow direction of the cut-off high-pressure flange connected steel gate valve should be upward from the bottom of the longitudinal valve disc, and the high-pressure flange connected steel gate valve can only be installed horizontally. When installing the steel gate valve with high-pressure flange connection, pay attention to the tightness to prevent leakage and affect the normal operation of the pipeline
