During double eccentricity valve opening or closing, the valve plate sealing face will be deviated gradually from and pressed into gradually the valve seat sealing face, thus reducing the mechanical abrasion and damage between the butterfly plate and the valve seat during opening or closing. For the double-eccentricity butterfly valve, when the butterfly plate rotates from 0° to 8°-12°, the butterfly plate sealing face will break away from the valve seat sealing face completely, thus reducing the mechanical abrasion and the extrusion corner travel during opening or closing the butterfly valve. With the reduction of mechanical abrasion and extrusion, the sealing performance and service life of the butterfly valve will be improved greatly.
