Main features
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.
Advantages:
1.Simple structure, small volume, light weight.
2.Small fluid resistance, full diameter ball valve basically no flow resistance.
3.Tight and reliable.It has two sealing surface, and the sealing surface material of the ball valve is widely used in a variety of plastics, good tightness, and can achieve complete sealing.It has also been widely used in vacuum systems.
4.Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90o, convenient for remote control.
5.Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
6.When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause the erosion of the valve sealing surface.
.
Common faults and troubleshooting methods of ball valves
1. The ball is washed over
Exclusion method: the assembly should be correct, the operation should be stable, not allowed to be used as throttle valve;The ball should be repaired in time after overturning and the sealing seat should be replaced.
2, when used as throttling function, sealing surface is damaged
Elimination method: the ball valve is not allowed to be used as throttle.
3. The sealing surface is crushed
Exclusion method: tighten the bolt at the valve seat should be uniform, the force should be small, would rather tighten several times, not too much and too tight at one time, the damaged sealing surface can be scraped and repaired.
