Valve Caps and bonnets are usually joined together with a mechanical fit to ensure proper valve operation. Mechanical fits are usually achieved through threaded or flanged connections. The connection method of the bonnet and the bonnet can be divided into two types: mechanical fit and sealing fit.
Mechanical fit is achieved through threaded or flanged connections. The threaded connection is suitable for small valves or pipeline systems. The connection between the bonnet and the bonnet generally adopts the matching method of external thread and internal thread to ensure that the connection is firm and not easy to loosen. Flange connection is suitable for large valves or piping systems. The connection between the bonnet and the bonnet is generally flanged. It is necessary to match the bonnet and bonnet with the flange connection to ensure a stable and sealed connection. The sealing fit is realized by materials such as sealing gaskets and sealing rings. Gaskets are generally made of soft materials, such as rubber, plastic, etc., and sealing rings are generally made of metal. When the connection between the bonnet and the bonnet is generally sealed, it is necessary to ensure that the material, size, hardness and other parameters of the gasket or ring match the operating environment of the valve to ensure the sealing effect. When selecting a valve, factors such as the working pressure, temperature and medium of the valve need to be considered to select the appropriate valve type and connection method. The connection method of the valve must be operated in strict accordance with the regulations to ensure the normal operation and safety of the valve. When maintaining the valve, it is also necessary to pay attention to whether the connection between the bonnet and the bonnet is tight and whether the seal is good. If problems such as looseness or leakage are found, measures should be taken in time for repair or replacement. This can ensure the normal operation of the valve and prevent safety accidents.
