How the ball valve works
Posted by Bundor valve
The opening and closing part of the ball valve is a ball with a round passage, rotating about the axis perpendicular to the passage, the ball rotates with the valve stem to achieve the purpose of opening and closing the passage.Ball valves can be closed tightly with only 90 degree rotation and very little torque.According to the needs of working conditions, the assembly of different driving devices to form a variety of different control methods of the ball valve, such as electric ball valve, pneumatic ball valve, hydraulic ball valve and so on.
Working principle of ball valve: when the ball valve rotates 90 degrees, the inlet and outlet should all appear spherical, so as to close the valve and cut off the flow of media.When the ball valve rotation 90 degrees, in the inlet and outlet should all appear the ball mouth, so as to open the flow, and basically no flow resistance.
Principle of ball valve structure:
1. Ball valve is not limited by the direction of installation, the flow of media can be arbitrary.Small fluid resistance, full size ball valves are basically no flow resistance.
2. Ball valve simple structure, relatively small volume, light weight, easy maintenance.
3. Be tight and reliable.It has two sealing surface, and the ball valve sealing surface material is widely used in various plastics, good sealing, can achieve complete sealing.It has also been widely used in vacuum systems.
4. Ball valve is suitable for frequent operation, fast opening and closing, light.Easy to operate, fast open and close, from full open to full close only rotation 90°, convenient for remote control.
5. Convenient maintenance, simple ball valve structure, sealing ring is generally active, disassembly and replacement are relatively convenient.
6. Good sealing performance of ball valve.When fully open or fully closed, the sealing surface of the ball and seat is isolated from the media, which will not cause erosion of the valve sealing surface when passing through.
7. Wide range of applications, sizes from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
8. Because the ball valve in the opening and closing process of wiping, so can be used in the medium with suspended solid particles.
9. Ball valve fluid resistance is small, no vibration, small noise.
