Ball Valve for Municipal Network
Introduction:
The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to be rotated 90 degrees and a small torque can be closed tightly. Ball valve is suitable for use as switch, cut-off valve, V-shaped ball valve.
In addition to paying attention to the pipeline parameters, the electric valve should also pay special attention to the environmental conditions of its use. Since the electric device in the electric valve is an electromechanical device, its use state is greatly affected by its use environment. Under normal conditions, special attention should be paid to the use of electric ball valves and butterfly valves in the following environments.
Advantages:
1. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.
2. Simple structure, small size and light weight.
3. Tight and reliable. It has two sealing surfaces, and the sealing surface materials of the ball valve are widely used in various plastics, which have good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.
4. Easy to operate, quick to open and close. It only needs to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and when the medium passes through, the valve sealing surface will not be eroded.
7. It has a wide range of applications, with diameters ranging from small to several 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.
