The history of cast steel ball pneumatic valve and working principle, application effect, 2)

and in People's Daily life. Pneumatic ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments.
with the rapid development of science and technology, production technology and product structure improvement from time to time, short years, has rapidly developed into a major pneumatic valve class. Western developed industrial countries, the use of pneumatic ball valve is rising year by year from time to time, countries, pneumatic ball valve is widely used in petroleum refining, long pipeline, chemical industry, paper making, pharmacy, water conservancy, electricity, municipal, iron and steel industries, a significant role 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, 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, cast steel ball appeared pneumatic valve Yu Shiji s. Methane and ethylene. Pneumatic valve pneumatic ball valve body can be a whole can also be combined
ball function and working principle of the pneumatic valve
is small in size, can make it big caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, various industries widely used. Pneumatic ball valve is to rely on the working principle of rotary pneumatic valve love to pneumatic valve open or occlusion. Engineers explain hong feng pneumatic valve, pneumatic ball valve switch light.
only close it is a ball, pneumatic ball valves and cocks pneumatic valve is belong to the same type of pneumatic valve. A sphere around the center line of the pneumatic valve body for rotation to achieve a pneumatic valves open and close.
has the following advantages: pneumatic ball valve in the line is mainly used to do cutting, distribution, and change the flow direction of medium. Pneumatic ball valve is widely used in recent years a new type of pneumatic valve.
the drag coefficient with section of equal length. Fluid resistance is small. Simple structure, small volume, light weight. The compact and reliable. Also has been widely used in the vacuum system. It is easy to operate. From open to close as long as the rotating °, is advantageous for the remote control. Easy maintenance. The assembly of seals are generally activities change is more convenient. The full open or full close. Medium through, does not cause erosion of pneumatic valve sealing surface. Wide range of application. To a few meters from high vacuum to high pressure can be applied.
