Use of eccentric valve, eccentric sphere and valve seat, valve stem rotation movement in common path self-centering, process closed more tightly closed, fully meet the sealing good. The valve ball and seat completely, eliminating the wear of the sealing ring, to overcome the traditional ball valve seat sealing surface and the spherical always wear problem, non-metallic elastic material is embedded in a metal seat, the seat of metal surface are well protected. This product is especially suitable for the iron and steel industry, aluminum, fiber, small solid particles, pulp, ash, oil gas and other media.
Product features:
■ the structure adopts eccentric tighten principle to achieve the brake tightly, regulation, closed through the transmission mechanism, the sealing ring is a metal surface hard contact seal, is located inside ball indoor valve double eccentric structure at the time of opening, the flow section is large, and the valve is not closed when the valve is not scour, erosion, opening the spool surface the valve seat along the progressive, effectively removed the scaling obstacles, to achieve a reliable seal. Francis it easy scaling solid precipitation on the two-phase mixture conveying particularly effective
■ the hemisphere valve with double metal, alloy surfacing on different parent materials, the seat is correspondingly surfacing through special processing, the sealing surface wear resistance, anti-corrosion, the synthesis of various types of high strength, to meet the needs of different occasions
A tight sealing, conveying the harmful gas up to zero leakage
■ sealing valve with compensation, when the valve to do after wear, then turn off a little, as the reliable sealing, prolong the service life of the. In addition, the user will clamping screw off, adjust or replace the valve seat is still available, to avoid the disadvantages of the valve seal failure, the whole.
