The working principle of a ball valve is to make the valve unobstructed or closed by rotating the valve stem. Ball valves are easy to operate, compact in size, can be made in large diameters, have reliable sealing, a simple structure, and are convenient for maintenance. The sealing surface and the ball surface are often in a closed state, making them less prone to erosion by the medium. They are widely used in various industries. Ball valves and plug valves belong to the same type of valves. The only difference is that the closing part of a ball valve is a sphere. The sphere rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. Ball valves are a new type of valve that has been widely adopted in recent years. They have the following advantages: 1 The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length. 2 Simple structure, small volume and light weight. 3 The ball valve is tight and reliable. Currently, plastic is widely used as the sealing surface material of the ball valve, which has good sealing performance and has also been widely used in vacuum systems. 4. It is easy to operate and opens and closes quickly. It only needs to be rotated 90° from fully open to fully closed, which is convenient for remote control. 5. The ball valve is easy to maintain. It has a simple structure and the sealing rings are usually movable, making disassembly and replacement relatively convenient. 6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve's sealing surfaces. 7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.
Ball valves have been widely applied in various sectors such as petroleum, chemical engineering, power generation, papermaking, atomic energy, aviation, and rockets, as well as in People's Daily lives
