Zusammenfassung:	The utility model relates to the technical field of valve structures, in particular to an overflow valve which comprises a valve body with an inner cavity. The valve cover is arranged on the valve body, an input port and an output port are formed in the valve cover, and the input port and the output port are respectively communicated with an inner cavity of the valve body; the diaphragm is provided with a plugging part and a connecting part connected to the peripheral side of the plugging part, the connecting part is tightly pressed on the valve body through the valve cover, the plugging part abuts against the input port to plug the input port, and a circle of buffering part used for buffering vibration of the diaphragm is arranged between the plugging part and the connecting part. The buffer part is arranged between the plugging part and the connecting part, so that redundant deformation exists between the plugging part and the connecting part when the diaphragm moves up and down, stress of the diaphragm can
