Adjustable round roller combined air locking rotary valve

The utility model relates to the technical field of rotary valves, in particular to an adjustable round roller combined air-locking rotary valve for conveying bulk powder and particle materials, whichcomprises a valve body, a round roller, a rotor valve core and a valve plate adjusting component, and the round roller and the rotor valve core are both rotationally mounted in the valve body. The valve plate is driven by the motor to rotate, the size of the feeding port is changed, materials can controllably flow into the storage groove of the rotor valve element, the storage groove in the rotorvalve element cannot be filled with the materials, quantitative feeding can be achieved, and therefore the situation that the materials are squeezed into the gap between the blade and the valve bodywhen the storage groove is filled with the materials is avoided; the rotary valve has the advantages that the rotary valve is simple in structure and convenient to operate, the phenomenon that materials are blocked and cut and
