Ball valve

Ball valve introduction

Ball Valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve.O type ball valve is used of on-off function, Ball valve is also be used for fluid regulation and control, hard sealing V-type ball valve v-type ball core and hard faced metal valve seat has a strong shear force, especially suitable for containing fiber, small solid particles and other media.The multi-port ball valve in the pipeline can not only flexibly control the confluence of media, shunt, and flow direction switch, but also close any channel and make the other two channels connected.Ball valve is divided into pneumatic ball valves, electric ball valves and manual ball valves according to the actuator.
 

Ball valve overview

Ball valve is widely used in petroleum refining, long-term pipeline, chemical, paper, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, in the national economy occupies a pivotal position.It has a rotation motion of 90 degrees. The body of the cock is a sphere with a circular through hole or channel passing through its axis.
The ball valve in the pipeline is mainly used to cut off, distribution and change the flow direction of the medium, it only needs to use a rotation of 90 degrees of operation and a small torque to close tight.Ball valve is most suitable for switch, cut off valve use, V - type ball valve.
 

Ball valve working feature

Compared with other types of valves,with angular stroke output torque, open quickly, smooth and reliable, widely used, and the following advantages:
1. The thrust bearing reduces the friction torque of the ball valve stem, making the stem stable and flexible for long-term operation.
2. Anti-static function: spring is set between the ball, ball valve stem and valve body to export the static electricity generated in the switching process.
3. Due to PTFE and other materials have good self-lubrication, small friction loss with the ball, so the service life of ball valve is long.
4. Small fluid resistance: ball valve is the smallest of all valve classification of fluid resistance, even if the diameter of the pneumatic ball valve, the fluid resistance is quite small.
5. Ball valve stem seal reliable: because the stem only rotation movement and do not do up and down movement, valve stem packing seal is not easy to destroy, and sealing ability increases with the increase of media pressure.
6. Ball valve seat sealing performance is good: the use of PTFE and other elastic materials made of sealing ring, the structure is easy to seal, and the sealing ability of ball valve increases with the increase of media pressure.
7. Small fluid resistance, full size of the ball valve is basically no flow resistance.
8. Simple structure, small volume and light weight.
9. Tight and reliable. Ball valve has two sealing surface, and the ball valve sealing material widely used in various plastics, good sealing, can achieve complete sealing.It has also been widely used in vacuum systems.
10. Ball valve is easy operation, fast opening and closing, rotation of 90° from full open to full close, convenient for remote control.
11. Convenient maintenance, ball valve structure is simple, sealing ring is generally active, dismantlement and replacement are relatively convenient.
12. When fully open or fully closed, the sealing surface of the ball and ball valve seat is isolated from the media, which will not cause the erosion of the valve sealing surface.
13. Ball valve is wide range of application, size from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
14. Due to the ball valve in the opening and closing process of wiping, so ball valve can be used with suspended solid particles in the medium.
