Evolution V-pneumatic valve and working principle

[来源:原创] [作者:admin] [日期:13-08-09] [点击:]

Pneumatic ball valve is as the name implies, v-shaped ball valve with pneumatic actuator, pneumatic actuator execution speed is relatively fast, and unnecessary workers do, to a great extent, save the human resources and time.
"V" development evolution and the working principle of the pneumatic ball valve
V evolved by the cut-off valve pneumatic ball valve. It rotates 90 degrees with the same method, different is the cock body is ball, a circular hole or channel through its axis. Spherical and opening ratio should be such, that is when the ball rotate 90 degrees, in the inlet and outlet should be completely present spherical, thereby blocking flow.
V pneumatic ball valve only need to the operation of the gas rotate 90 degrees and small rotational torque can be closed tightly. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Usually do think most suitable direct ball valve open and close, but recent development has put a ball valve designed to make it with throttling and control flow. 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. Ball valve body can be a whole, also can be combined.
A, V reality effect of V type pneumatic ball valve pneumatic ball valve is to rely on the working principle of rotary valve love to keep the valve open 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.
V pneumatic ball valve and plug valve is belong to one type of valve, only its closure is a ball, the ball around the center line of the body as a rotation to achieve a kind of open and close the valve.
V pneumatic ball valve in the line is mainly used for cutting speed is quick, distribution, and change the flow direction of medium.
Pneumatic ball valve is widely used in recent years a new type of valve, it has the following advantages:
1. The fluid resistance is small, the resistance coefficient with section of equal length.
2. Simple structure, small volume, light weight.
3. Compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system.
4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.
5. Convenient maintenance, simple structure, pneumatic ball valve sealing ring are generally activities, remove the replacement is more convenient.
6. The full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion.
7. Applicable scope is wide, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.
Stainless steel pneumatic ball valve has been widely used in petroleum, chemical, power, papermaking, atomic energy, aerospace, rocket and other departments, as well as People's Daily life.
Above is V type pneumatic ball valve factory is always fine Sue valve co., LTD., evolution and development of V type pneumatic ball valve working principle in detail, if you are looking for pneumatic ball valve price, manufacturer, model, pictures have any questions, please contact us to get the latest information of pneumatic ball valve.
