The ball valve is suitable for frequent operation, and it is quick and easy to open and close. The fluid resistance is small. The utility model has the advantages of simple structure, relatively small volume, light weight and convenient maintenance. The sealing performance is good, and it is not restricted by the installation direction, and the flow direction of the medium can be arbitrary. No vibration, low noise.

　　 According to the structure, the ball valve can be divided into: floating ball valve, fixed ball valve, elastic ball valve and oil seal ball valve; according to the channel can be divided into straight energy type, angle type and three general formula, etc., the three types can be divided into T shape and L shape two Kind. According to the connection work, it can be divided into three types: threaded connection, flanged connection and welded type.
　　
Floating ball valve ball ball ball ball ball ball ball ball ball ball fixed ball valve fixed ball valve ball ball fixed ball valve is a new type of high performance ball valve, suitable for long-distance pipelines and general industrial pipelines, Special considerations have been made in the design of safety and harsh environments. Suitable for a variety of corrosive and non-corrosive media.
　　
Compared with the floating ball valve, the force generated by the fluid pressure on the ball in the pipe during operation is transmitted to the upper and lower bearings, the ball does not move, and the valve seal is pushed by the spring and the medium to push the valve seat, so the valve seat It will not withstand excessive pressure, so the fixed ball valve seat has small deformation, light operating torque, reliable sealing performance and long service life. Especially suitable for high pressure, large diameter applications. Sanjing Valve Technology Department provides
