| 球阀主要特性 | ||
The main characteristics of the ball valve are its compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often in a closed state, not easy to be washed away by the medium, easy to operate and maintain, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene, etc. It is widely used in various industries. Ball valve body can be integral, can also be combined. 1. Ball valves are not limited by the installation direction, and the flow direction of the medium can be arbitrary. The fluid resistance is small, and the full-diameter ball valve has basically no flow resistance. 2. Ball valve structure is simple, relatively small size, light weight, easy maintenance. 3. Tight and reliable. It has two sealing surfaces, and the sealing surface material of the ball valve is widely used in various plastics, which has good sealing property and can achieve complete sealing. It has also been widely used in vacuum systems. 4. Ball valve is suitable for frequent operation, opening and closing quickly, lightweight. Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control. 5. Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. 6. Ball valve sealing performance is good. When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when it passes through. Seven. Wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. 8. Because the ball valve has wipeability during opening and closing, it can be used in media with suspended solid particles. 9, ball valve fluid resistance is small. 10, ball valve no vibration, small noise. |
