One-piece ball valve is a relatively new type of ball valve category, it has some unique advantages of its own structure, such as the switch without friction, sealing is not easy to wear, the opening and closing moment is small. This reduces the specification of the fitted actuator. With multi-loop electric actuator, medium adjustment and close cut off. It is widely applicable to petrochemical urban water supply and drainage conditions.
The working principle of wide ball valve
is by rotating valve Ball disc to make the valve smooth or blocked. The ball valve switch is light and small, which can be made into a large diameter, reliable seal, simple structure and convenient maintenance. The sealing surface and sphere are often closed, which is not easy to be eroded by the medium, and has been widely used in various industries.
Advantge:
A. Fluid resistance is small, and its resistance coefficient is equal to the pipe segment of the same length.
B. Simple structure, small volume and light weight.
C. Close and reliable, the current sealing surface material of the ball valve is widely used in plastic, good sealing ability, and has been widely used in the vacuum system.
D. Convenient operation, rapid opening and closing. From full opening to full closing, as long as 90° to facilitate long-distance control.
E. Convenient maintenance, simple ball valve structure, the sealing ring is generally active, disassembly and replacement are more convenient.
F. During full opening or full closure, the sealing surface of the sphere and the valve seat is isolated from the medium. When the medium passes through, it will not cause the erosion of the valve sealing surface.
G. A wide range of applications, from a small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. When the ball rotates 90 degrees, the ball should be presented at the inlet and exit to truncate the flow.
