[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate, add flange gaskets between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already have flange plates, which also belong to flange connection. Flange connection is an important connection method for pipeline construction.
