Jacket type eccentric ball characteristic of the pneumatic valve

jacket type eccentric ball the characteristics of the pneumatic valve is as follows:
a, seal ( Pneumatic valve core, pneumatic valve seat) — — Double metal, metal sphere band hard seal, for fire and explosion prevention;
2, seal characters, pneumatic valve core and pneumatic seat sealing is spherical line contact, for zero leakage by three-dimensional eccentric;
3, seal of the pneumatic valve core with offsets, pneumatic valve using a long time to find seal wear, just loosen handwheel the lateral limit of the bolt, closing to turn a little, still can realize reliable seal, prolong service life.
4, pressure can be set off, adjust or change the pneumatic valve seat, still can continue to use pneumatic valve, avoiding the current number of pneumatic valve seal failure after the disadvantages of the dead.
hemisphere pneumatic valve can be divided into: according to the use of general pneumatic valve, pneumatic valve, slurry pipeline is special pneumatic valve, pneumatic valve for gas, petrochemical special pneumatic valve, pneumatic valve for pulverized coal injection six big series. Transmission means has manual, pneumatic, electric three, eight classes ( PN。 ~。 Mpa） Hundreds of specifications ( The hemisphere of ~ pneumatic valve products. In petroleum, chemical industry, metallurgy, electric power, gas and other industries is the brake pneumatic valve, pneumatic valve, globe Y type pneumatic valve, ball valve is the upgrading of products. Is now popular in the steel industry of pulverized coal injection, pulp, mother liquor and alumina powder conveying alumina industry, electric power industries hydraulic ( Or dry) Ash, petrochemical industry, gas industry, etc.
