Definition of high platform ball valve and description of ball valve identification skills

The high-platform ball valve is a relatively new type of ball valve. It has some unique features unique to its structure. For example, the switch has no friction, the seal is not easy to wear, and the opening and closing torque is small. Mainly used to cut, distribute and change the flow direction of the medium. It is the same type of valve as the flange gate valve. The difference is that the closing member is a sphere, and the ball rotates around the center line of the valve body to open and close a valve. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium.
Ball valves are mainly divided into one-piece, two-piece, three-piece and high and low ball valves. The main difference between one-piece, two-piece and three-piece is the component of the valve body. One-piece is one-piece, two-piece is composed of two parts, and three-piece is composed of left and right end caps and intermediate valve body. It is easy to disassemble to distinguish their use, and the three-piece pressure is higher than the other two. The high platform is mainly used to install the actuator (pneumatic head, electric head). There is no such thing as a low platform, either a platform or an ordinary platform. In addition, the chip ball valve can also be called a quick ball valve, the main reason is that the torque required to open and close is small.
The main application advantages of high-platform ball valves are the following:
1. The fluid resistance is small, and the resistance coefficient is equal to the pipe length of the same length.
2. Simple structure, small size and light weight.
3. Close and reliable, the sealing surface material of the ball valve is widely used in plastics and has good sealing performance, and has been widely used in vacuum systems.
4. It is easy to operate, and it can be opened and closed quickly. It can be rotated by 90° from full opening to full closing, which is convenient for long-distance control.
5. Easy maintenance, the ball valve has a simple structure, the sealing ring is generally active, and it is convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause erosion of the sealing surface of the valve.
7. Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, all the spheres should appear at the entrance and exit, thus cutting off the flow.
