Explosion-proof electric adjusting flange butterfly pneumatic valve adopt three partial hardness sealing structure, sealing for the metal to metal seal, pneumatic valve seat and disc almost no wear and tear, have the close tight sealing function, whether in the case of low and high temperature, has good sealing performance, corrosion resistance, long service life, etc.
Widely used in medium temperature & le;
425 ℃ of metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction and other industrial pipelines, used to adjust flow cutoff and body.
explosion-proof electric adjusting flange hard seal butterfly pneumatic valve adopt three-dimensional eccentric principle design, make the space of the sealing surface movement to achieve ideal, no friction, no interference with each other, together with sealing material is properly selected, so that the adjustment of the pneumatic valve sealing, corrosion resistance, high temperature resistance and wear resistance has been a reliable guarantee. Its main characteristics are small open torque, flexible, convenient and saving energy; Reliable seal performance, zero leakage; High pressure resistance, corrosion resistance, wear resistance, long service life, etc. Pneumatic valve shaft center and pneumatic valve plate sealing surface to form a migration; Pneumatic valve shaft center and the center line of the pneumatic valve body to form a migration; The center line of the pneumatic valve sealing surface and the center line of the pneumatic valve form an offset.
3 partial hardness seal butterfly pneumatic valve principle chart
pneumatic valve stem axis between the butterfly plate sealing surface and offset A size A, and with the pneumatic valve body channel axis offset A size B, pneumatic seat and pneumatic rotary axis body form an eccentric Angle & alpha channel axis; , the formation of triple eccentric butterfly pneumatic valve. Butterfly pneumatic valve & from 0 deg; ~ 90度; Open when the butterfly plate seal face moment in open immediately from pneumatic valve seat sealing surface, in its 90 & deg; ~ 0度; Is closed, only in the closing moments, the butterfly plate cone sealing surface will contact and pressure pneumatic conical seating. So pneumatic seat with no friction between the sealing surface of disc, in addition to the wear and the possibility of leakage.
