Double eccentric butterfly valve d73h/d43h directly supplied by the manufacture

Double eccentric butterfly valve details of double eccentric butterfly valve directly supplied by d73h/d43h manufacturer
On the basis of the double eccentric butterfly valve, the double eccentric butterfly valve which is the most widely used at present is further improved
The utility model is characterized in that the shaft center of the valve rod deviates from both the center of the butterfly plate and the center of the body
The double eccentricity effect enables the butterfly plate to quickly separate from the valve seat after the valve is opened, greatly eliminating the unnecessary excessive extrusion and scratching between the butterfly plate and the valve seat, reducing the opening resistance, reducing the wear, and improving the service life of the valve seat
