The Working Principle and Characteristics of the Ball Valve
The ball valve evolved from the plug valve. It has the same 90-degree rotation and lifting action, but the difference is that the cock body is a sphere with a circular hole or channel passing through its axis. The proportion of the sphere and the passage opening should be such that when the sphere rotates 90 degrees. The inlet and outlet should all be spherical, so as to cut off the flow. The ball valve can be closed tightly with only 90-degree rotation and very small rotation torque. The equal inner cavity of the valve body provides a straight flow passage with little resistance for the medium.
It is generally believed that the ball valve is most suitable for direct opening and closing, but recent development has designed the ball valve to be used for throttling and flow control. The main features of the ball valve are its compact structure. It is easy to have the operation and maintenance. It is applicable to water, solvent, acid, natural gas and other general working media, as well as media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The valve body of the ball valve can be integral or combined.
What is the ball valve?
The ball valve is a ball with a circular channel as the opening and closing parts. The ball rotates with the stem to realize the opening and closing action of the valve. The opening and closing part of the ball valve is a perforated sphere that rotates perpendicular to the axis of the channel to achieve the purpose of opening and closing the channel. The ball valve is mainly used to open and close pipes and equipment media.
The working principle of the ball valve
The ball valve has the same 90-degree rotation action, but the difference is that the cock body is a sphere, with a circular hole or channel passing through its axis. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It can be closed tightly with only a 90-degree rotation and small rotating torque. The ball valve is most suitable to be used as a switch and shut-off valve, but recent development has designed the ball valve to be used for throttling and flow control, such as V-type ball valves.
The main features of the ball valve are its compact structure, reliable sealing, simple structure, and convenient maintenance. The sealing surface and spherical surface are often closed. It is not easily eroded by the medium, and is easy to operate and maintain. It is suitable for water, solvent, acid, natural gas and other general working media. It is also suitable for media with poor working conditions, such as oxygen, hydrogen peroxide, methane, ethylene, etc. It is widely used in various industries. The valve body of ball valves can be combined or integral.
Main characteristics of the ball valve
1. The ball valve is not limited 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 basically has no flow resistance.
2. The ball valve is simple in structure, small in relative volume, light in weight and convenient for maintenance.
3. Tight and reliable. It has two sealing surfaces. At present, various plastics are widely used as the sealing surface materials of the ball valve, which has good sealing performance and can realize complete sealing. It has also been widely used in vacuum systems.
4. The ball valve is suitable for regular operation, with quick and convenient opening and closing. It is easy to operate and can be opened and closed quickly. Only 90 degrees rotation is required from full opening to full closing, which is convenient for the remote control.
5. It is easy to maintain. The ball valve is simple in structure. The sealing ring is generally movable, and it is convenient to disassemble and replace.
6. The ball valve has good sealing performance. When the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, ranging from a few millimeters to several meters in diameter, from high vacuum to high pressure.
8. The ball valve can be used in a medium with suspended solid particles due to its wiping property during opening and closing.
9. The ball valve has small fluid resistance.
10. The ball valve has no vibration and low noise.
