[0002] Pipe fittings are a general term for components in piping systems that perform functions such as connection, control, direction change, diversion, sealing, and support. Connecting fittings are used to connect pipes to each other or to devices, parts, and equipment. They are widely used in construction, industrial production, and public facilities, primarily for transporting fluids such as air, gas, water, steam, chemicals, and petroleum. They are also widely used in shipbuilding.

[0003] When connecting pipe fittings for use, the connection of the casing is mainly achieved by matching the threaded sleeve and the internal thread, and the bolt and the nut. However, during the use of the casing, due to the flow of water inside, the inner wall of the casing is easily subjected to pressure. If the pressure is too high, it is easy to cause the connection to loosen or be damaged, thereby affecting the normal use of the casing. Utility Model Content
