Structural principle of ball valve
1. The ball valve is not restricted by the installation direction, and the flow direction of the medium can be arbitrary. The fluid resistance is small, and the full-bore ball valve has basically no flow resistance.
2. The ball valve has a simple structure, is relatively small in size, light in weight, and easy to maintain.
3. Tight and reliable. It has two sealing surfaces, and the sealing surface materials of ball valves currently use various plastics, which have good sealing properties and can achieve complete sealing. It has also been widely used in vacuum systems.
4． Ball valves are suitable for frequent operations, opening and closing quickly and easily. It is easy to operate and opens and closes quickly. It only needs to be rotated 90° from fully open to fully closed, which is convenient for long-distance control.
5. It is easy to maintain. The ball valve has a simple structure and the sealing ring is generally movable, making it easy to disassemble and replace.
6. The ball valve has good sealing performance. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface.
7． It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure.
8. Since the ball valve has wiping properties during the opening and closing process, it can be used in media with suspended solid particles.
9. The ball valve has small fluid resistance, no vibration and low noise.
