Taizhou valve manufacturers on the valve knowledge: ball valve

Ball valve and plug valve are the same type of valve, only its closing part is a ball, the ball revolves around the center line of the valve body to achieve open, closed a valve. Ball valve in the pipeline is mainly used to cut off, distribution and change the flow direction of the medium. Ball valve is widely used in recent years is a new type of valve ball valve and plug valve is the same type of valve, only its closing part is a ball, the ball around the center line of the valve body for rotation to open and close a valve.

Ball valve in the pipeline is mainly used to cut off, distribution and change the flow direction of the medium. Ball valve is a new type of valve which has been widely used in recent years. It has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length.

2. Simple structure, small volume, light weight.

3. Tight and reliable, the sealing surface material of ball valve is widely used plastic, good sealing, and has been widely used in vacuum system.

4. Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90°, convenient for remote control.

5. Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly 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, it will not cause the erosion of the valve sealing surface.

7. Applicable to a wide range of sizes from small to a few millimeters to a few meters, from high vacuum to high pressure can be used.

Ball valve has been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as People’s Daily life.
