JA22H static weighing type safety working principle of the pneumatic valve

JAH static weighing type safety pneumatic valve specifications pneumatic valve ( 安全阀) Is automatically according to the working pressure of the pressure system opening and closing, generally installed in a closed system of the equipment or piping safety protection system. When the pressure in the equipment or pipeline exceeds safety pneumatic valve set pressure, pressure relief automatically open, ensure that the equipment and piping within the medium pressure in the set pressure, protect the equipment and piping work, prevent accidents and reduce losses.
security pneumatic valve structure mainly include two categories: spring type and lever type. With pneumatic spring type refers to the pneumatic valve seat valve sealing force by the spring. Leveraged by the reaction between the lever and weight. With the needs of large capacity, and there is a kind of impulse type safety pneumatic valve, pneumatic valve, also known as the guide type safety by the main security of pneumatic valve and auxiliary pneumatic valve. When the pipeline within the medium pressure in excess of the prescribed pressure value, the auxiliary pneumatic valve to open, medium along the catheter into the main security pneumatic valve, pneumatic valve and the main security opened, reduce the medium pressure increased.
security pneumatic valve pneumatic seat diameter and air emissions depends on the opening of the disc height, also can be divided into two kinds: tiny qi type open height is pneumatic valve seat diameter ( /) ~ ( /) , the rev is ( /) ~ ( /) 。
in addition, as the requirement of use is different, have closed and not closed. Enclosed the discharge medium is not leaked out, and all along the outlet, commonly used in toxic and corrosive medium. Enclosed is commonly used in non-toxic or non-corrosive medium.
