The two piece ball valve rotates around the center line of the valve body to open and close the valve.
Two piece silk ball valve, three piece ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow. A piece of ball valve, two piece ball valve, three piece ball valve, is widely used in recent years, a new type of valve.
Convenient maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
The resistance of a/ fluid is small, and its drag coefficient is equal to the pipe length of the same length.
B/ is simple in structure, small in size and light in weight.
C/ is close and reliable. At present, the sealing surface material of ball valve is widely used in plastics and has good sealing performance. It has been widely used in vacuum system.
D/ has the advantages of convenient operation, open and close rapidly, from fully open to fully closed as long as the rotation of 90 degrees and facilitate remote control.
E/ maintenance is convenient, the ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
When the f/ is fully open or fully closed, the sealing surface of the ball and the valve seat is separated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.
G/ has a wide range of applications, ranging from small to several millimeters, large to several meters, from high vacuum, high pressure can be applied.
