[0002] Valves are various valves used in various types and specifications, from the simplest stop valve to the extremely complex automatic control system. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. They are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters of the conveying medium, temperature, pressure and flow. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.

[0003] In the prior art, there are two methods for connecting valves to pipes: the first is to first thread one end of the pipe, then wrap it with tape, and then screw the valve or pump onto the pipe; the second is flange connection, first thread the pipe into the flange, then connect it to the corresponding flange on the valve or pump body with bolts, and place a rubber asbestos gasket between the two flanges to achieve a sealed connection.
