Working principle and characteristics of high pressure ball valve



High-pressure ball valve working principle: high-pressure ball valve The ball valve has a rotation of 90 degrees, the body of the plug is a sphere, with a circular through hole or passage through its axis. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. It only needs to be rotated 90 degrees and the torque can be closed tightly. Ball valves are best suited for use as switching and shut-off valves, but recent developments have designed ball valves to provide throttling and control flow, such as V-ball valves.
The main features of the high-pressure ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and the spherical surface are often closed, not easily eroded by the medium, easy to operate and maintain, suitable for water, solvent, acid and natural gas. Working medium, but also suitable for medium with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, which are widely used in various industries. The ball valve body may be integral or combined.
Eccentric ball valve. Forged steel ball valve direct buried ball valve hard seal ball valve high pressure ball valve and other high pressure ball valve advantages: The fluid resistance is small, and the full-bore ball valve has substantially no flow resistance. . The structure is simple, small in size and light in weight. 3. Tight and reliable. It has two sealing faces, and the sealing surface material of the ball valve is widely used in various plastics, and has good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems. . The operation is convenient, the opening and closing is rapid, and the rotation is 90° from full opening to full closing, which is convenient for long-distance control. 5. The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally movable, and the disassembly and replacement are relatively convenient. . When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve. . Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. . Since the ball valve is wiping during opening and closing, it can be used in a medium with suspended solid particles.
