Pneumatic valve related introduction

Pneumatic valve closing is individual, body around the center line of the valve body rotation to achieve a kind of open and close the valve. Pneumatic valve in the pipeline is mainly used for cutting speed is quick, distribution, and change the flow direction of medium. Pneumatic valve is a new type of valve, pneumatic valve and plug valve is belong to one type of valve, the next to introduce the characteristics of pneumatic valve. Pneumatic valve features:, simple structure, small volume, light weight. , small fluid resistance, the resistance coefficient with section of equal length. , easy to operate, open and close quickly, from open to close as long as the rotating °, is advantageous for the remote control. And reliable closely, valve sealing surface of materials widely used plastic, sealing good, also has been widely used in the vacuum system. Pneumatic valve has simple structure, convenient maintenance, and seals are generally activities, remove the replacement is more convenient. , in full open or full close, body and seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion. , wide applicable scope, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. , because of the pneumatic valve is gas that is used by the power supply is commonly. - - - - - - 。 MPa pressure, is relatively safe. Pneumatic valve if air leakage, the relative hydraulic, electric, gas can directly discharge, no pollution to the environment, and has higher security. , relative to manual and turbine rotating valve, pneumatic valve can be large caliber configuration, manual and turbine rotational valve is generally below DN caliber, pneumatic valve DN diameter can be achieved. With the pneumatic valve in the petroleum, chemical, power, papermaking, atomic energy, aviation, rockets and other departments, and widely used in People's Daily life. To speed up the study of pneumatic valve has become a job, many experts and scholars believe that pneumatic valve in the future will be more satisfactory products.
