Abstract
The invention discloses a hinge type buoyancy tank opening flap valve, and belongs to a buoyancy tank opening flap valve. The hinge type buoyancy tank opening flap valve mainly solves technical problems of small opening angle, high head loss, difficulty in being completely sealed and the like of an existing valve. The technical scheme includes that adjusting plates (4) are arranged on side surfaces of valves of the hinge type buoyancy tank opening flap valve, hinges are arranged on the adjusting plates (4) and comprise hinge lugs (5) and hinge pins (6) with semicircular heads, the hinge pins (6) with the semicircular heads are arranged in the hinge lugs (5), buoyancy tank doors are mounted on the hinge pins (6) with the semicircular heads, and each hinge is vertically arranged and is inwardly inclined by an angle of 3 degrees. Each buoyancy tank door is powered by horizontal component force of the dead weight of the buoyancy tank door, so that purposes that the hinge type buoyancy tank opening flap valve has a large opening angle, is low in head loss and can be automatically closed and completely sealed are achieved. The hinge type buoyancy tank opening flap valve is mainly used for cut-off of irrigation and drainage pumping stations.
