The v-ball valve is needed to have the role of flow regulation and the working condition of the medium for the impurity particles of the fluid.
1. Ball valve has the same 90 degree rotary action, the difference is that the plug body is a sphere, with a round hole or through or channel through its axis of the channel. Ball valve is mainly used for pipeline cut off, distribution and change the direction of flow of the medium, it only need to rotate 90 degrees operation, a small torque can be tightly closed. Ball valves are suitable for switching and cutting valves, but in recent years the development of ball valves with throttling and control flow, such as v-ball valves.
2. Suitable for regular opening and closing operations, easy to open and close, low fluid resistance, simple structure, relatively small size, light weight, easy to maintain, good sealing performance, the influence of the direction of media flow, no vibration, no noise.
Eccentric half ball valves do not have flow regulation, can also be used for fluids containing impurity particles.
1. Small fluid resistance, its resistance coefficient is equal to the same length.
2. Simple structure, small volume, light weight
3. Ball valve sealing material is tight and reliable, widely used in plastics, good sealing performance, widely used in vacuum systems.
4. Simple operation, fast opening and closing, from fully open to fully closed only rotate 90, easy to control over long distances.
5. The utility model has the advantages of easy maintenance, simple structure of ball valve, simple structure of movable sealing ring, easy disassembly and replacement.
6. When fully open or fully closed, the sealing surface of the ball and seat is isolated from the medium. When the medium passes through, it will not cause corrosion of the sealing surface of the valve.
7. Wide range of applications, with diameters ranging from small to several millimeters, and sizes ranging from high vacuum to high pressure can be applied.
When the ball rotates 90 degrees, it should all show spherical surface at the inlet and outlet, thus cutting off the flow. Eccentric half ball valve is a relatively new type of ball valve, it has its own structure unique advantages, such as frictionless switching, sealing is not easy to wear, small switching torque. This reduces adapter specifications. Adopting multi-rotation electric actuator, it can regulate and cut off the medium. It is widely used in petroleum, chemical, urban water supply and drainage industries.
