Buffering overflow valve

The invention relates to the field of overflow valves, in particular to a buffering overflow valve which comprises a valve element, a valve shell, a water inlet, a water outlet, a rubber pad and a pressure detection mechanism. The valve element is located in the valve shell which is a hollow block. One end of the valve shell is fixedly connected with the water inlet, and the other end is fixedly connected with the water outlet; the valve element is provided with the pressure buffering mechanism, when the pressure of the water inlet exceeds a preset value, the pressure buffering mechanism exposes the through hole for preventing the pressure from being too high to buffer the pressure and monitor the pressure value in real time, the current water pressure in the overflow valve can be visually displayed, an independent working area is provided for the spring, and the spring is prevented from being eroded by a water body; the application area of the overflow valve is enlarged, and the applicability of the overflow
