- pneumatic ball valve Cast steel ball and working principle of the pneumatic valve

cast steel ball pneumatic valve was Yu Shiji s, with the rapid development of science and technology, the continuous improvement of production technology and product structure, in the short years, has rapidly developed into a major pneumatic valve class. Industrial developed country in the western countries, the use of pneumatic ball valve is constantly rising year by year, in our country, pneumatic ball valve is widely used in petroleum refining, long pipeline, chemical industry, paper making, pharmacy, water conservancy, electric power, municipal, industries such as steel, holds the pivotal status in the national economy. Pneumatic ball valve only need to use rotation operation and small rotational torque can be closed tight. Full equality of the pneumatic valve body cavity for medium resistance is very small, straight flow channel. Generally think of pneumatic ball valve is suitable for direct to do the most open and close, but recent development has pneumatic ball valve designed to make it with throttling and control flow. Pneumatic ball valve itself is the main characteristics of compact structure, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Pneumatic valve pneumatic ball valve body can be as a whole, also can be combined. Pneumatic ball valve function and working principle of the pneumatic ball valve is to rely on the working principle of pneumatic valve pneumatic valve love to make smooth rotation or occlusion. Pneumatic ball valve switch lightweight, small size, can make a large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries. Pneumatic ball valves and cocks pneumatic valve is belong to the same type of pneumatic valves, only its closure is a ball, the ball goes around the center line of the pneumatic valve body for a pneumatic valves to open and close. Pneumatic ball valve in the line is mainly used to do cutting, distribution, and change the flow direction of medium. Fluid resistance is small, its resistance coefficient with section of equal length. Simple structure, small volume, light weight. Close and reliable, the pneumatic ball valve sealing surface of materials widely used plastic, sealing good, also has been widely used in the vacuum system. Easy to operate, open and close quickly, from open to close as long as the rotating °, is advantageous for the remote control. Pneumatic valve has simple structure, convenient maintenance, the ball sealing ring are generally activities, remove the replacement is more convenient. In full open or full close, the sphere and the pneumatic valve seat sealing surface and the dielectric isolation, medium through, can not cause erosion of pneumatic valve sealing surface. Applicability is wide and size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. Pneumatic ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, as well as People's Daily life.
