ZhengFeng's eccentric hemispherical valve is developed on the basis of digesting and absorbing the foreign double-clamped high-flow straight through valve, and its structure adopts the principle of eccentric-wedging to tighten, adjust and close the gate through the transmission mechanism.



Principle:
Double eccentric structure in the opening of the valve core is located in the ball chamber, the flow cross section is large, and the valve is not washed, closed the valve core goal along the valve seat gradually, effectively remove the structural obstacles, to achieve reliable sealing.
Features:
1. The valve hemisphere uses the bimetal, the base material surfacing welding different alloy, the valve seat surface surfacing welding passes through the special processing, the anticorrosion, the wear-resisting, the high strength, satisfies the different occasion demand;
2. Tight seal, transmission of harmful gas can achieve zero leakage;
3. The valve core of sealing pair has compensatory amount, after when valve seat is worn, close again rotate a few, still can seal reliably, prolong service life;
4. The valve seat can still be used after adjusting or replacing by unscrewing the compression nut to avoid the drawback of scrapping after seal failure.
