Curved-surface circular tooth-edge float valve

A curved surface circular tooth edge floating valve is provided with a circular valve plate, the valve plate is provided with a circular concave curved surface concentric with the outer circle of the valve plate, and five circular holes are formed in the bottom and the middle of the concave curved surface. Three valve legs with the same length are evenly arranged on the circumference of the round valve plate, a valve foot is arranged at the lower end of each valve leg, and the circumference edge of the round valve plate is in the shape of a zigzag edge folded downwards. The technical problem to be solved by the utility model is to provide the curved-surface circular tooth-edge float valve which can strengthen the mass transfer effect of gas and liquid at the upper part of the float valve and effectively avoid the defect of poor contact of the gas and the liquid at the upper part of the F1 float valve. And the gas-liquid contact of the tower plate is stable and uniform, and the operation stability and the mass
