Do you know the advantages of fixed ball valve?

The flange fixed ball valve is a kind of valve. It belongs to the same type of valve as the flanged gate valve, flanged butterfly valve, and oxygen relief valve. The difference is that its closing part is a sphere, and the sphere rotates around the center line of the valve body to open and shut down. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. Ball valves have been widely used in recent years. The following Xiaobian shares the advantages of the lower flange fixed ball valve and the opening and closing process:

First, the advantages of flange fixed ball valve 1, the fluid resistance is small, the resistance coefficient and the same length of the pipe section is equal.

2, simple structure, small size, light weight.

3, close and reliable, the current ball valve sealing surface materials are widely used plastic, good sealing, has also been widely used in the vacuum system.

4, easy to operate, open and close quickly, from full open to full off as long as the rotation of 90 °, easy to control long-distance.

5, easy maintenance, ball valve structure is simple, the seal ring is generally active, removal and replacement are more convenient.

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 through, the sealing surface of the valve will not be eroded.

7, a wide range of applications, from a small diameter 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 at the entrance and exit should be spherical, thus cutting off the flow.
