The ball of the ball valve is floating. Under the action of medium pressure, the ball can produce a certain displacement and compress on the sealing surface of the outlet end to ensure the sealing of the outlet end.
Floating ball valve has simple structure and good sealing, but the ball bears all the load of the working medium and passes to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to high pressure impact, the ball may be offset. This structure is generally used in low and medium pressure ball valves.
Ball valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, It is widely used in various industries. The ball valve body can be integral or combined.
