the actual function of stainless steel pneumatic ball valve

The working principle of stainless steel pneumatic ball valve is to rely on the rotating valve to make the valve unobstructed or blocked. Pneumatic ball valves are light on and off, small in size, can be made into large diameters, have reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are always in a closed state and are not easily eroded by the medium. They are widely used in various industries. Stainless steel pneumatic ball valve and plug valve belong to the same type of valve. Only its closing part is a ball. The ball rotates around the center line of the valve body to open and close. Stainless steel pneumatic ball valves are mainly used in pipelines for fast cutting, distribution and changing the flow direction of the medium. Pneumatic ball valve is a new type of valve that has been widely used in recent years. It has 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 size and light weight. 3. Tight and reliable. At present, plastic is widely used as the sealing surface material of ball valves, which has good sealing performance and has also been widely used in vacuum systems. 4. Easy to operate, quick to open and close, just rotate 90° from fully open to fully closed, convenient for long-distance control. 5. Easy to maintain, the pneumatic ball valve has a simple structure, the sealing ring is generally movable, and it is easy to disassemble and replace. 6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface. 7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure. Stainless steel pneumatic ball valves have been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rocket and other departments, as well as in people's daily life.
