The technical solution of the utility model is: a kind of bivalve buffer valve, it comprises valve body, valve plate, valve shaft, axle bed and diversion seat, the valve plate that is positioned at the diversion seat top is divided into left valve plate and right valve plate, left valve plate is affixed by left hangers and left valve shaft, left valve shaft is fixed in the valve body left side by left bracket, right valve plate is affixed by right hangers and right valve shaft, and right valve shaft is fixed in the valve body right side by right axle seat.
Diversion seat is provided with slow closing device described in the such scheme, slow closing device integral body fits in the diversion seat, slow closing device comprises the Slow Close axle, back-up ring, guide sleeve, sliding sleeve, spring and accent stream plug screw, the upper end of guide sleeve is fixed on the diversion seat by back-up ring, described Slow Close axle one end fits in the guide sleeve, the other end stretches out guide sleeve and contacts with the valve plate that is in closed state, the below of Slow Close axle is provided with the sliding sleeve that can move in the guide sleeve in guide sleeve, the diversion seat of described guide sleeve below is provided with the ladder-type groove, the interior adaptive spring that contacts with sliding sleeve that has of described groove, groove one side is by transferring the exterior of stream plug screw and diversion seat, described slow closing device also be divided into left slow closing device and right slow closing device corresponding to valve plate.
Left valve plate described in the such scheme and right valve plate are coated with respectively the nitrile butadiene rubber layer outward.
The beneficial effects of the utility model are by diversion seat being set and left and right sides double valve plates reduces the unlatching resistance, saving energy consumption, be provided with slow closing device and strengthen the Slow Close effect below valve plate, and valve plate is coated with the nitrile butadiene rubber layer and has prolonged working life.
