Parts of rubber disc check valves have triple, from rubber disc check valve is the name we can see: body, rubber disc and cover three, therefore, the name of the rubber disc check valve, and is very convenient for us to remember. This kind of rubber disc check valves are very useful, it is the biggest characteristic can make the loss of faucet smaller, with negligible role plays the biggest key.Three plate butt welding ball valve has the following advantages: small fluid resistance, the resistance coefficient with section of equal length. Simple structure, small volume, light weight. 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. Easy to operate, open and close 12 needle valve quickly, from open to close just rotate 90 °, is advantageous for the remote control.
Convenient maintenance, simple structure of ball valve, sealing ring, which generally remove replacement is more convenient. In 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. Applicability is wide and 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 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.
Pneumatic flanged ball valves only need gas rotate for 90 degrees operation 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 needle valve manufacturer 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.
