A mutual and electric double-controlled baffle type one-way overspeed shutoff valve comprises a casing, a machine cover arranged at the top of the casing, an oil inlet, an oil outlet and a bottom plate, wherein a vertical frame is arranged on the bottom plate, a valve plate assembly and a manual operation assembly are arranged at the oil outlet, and the valve plate assembly comprises an activating plate hinged to the bottom plate, a reed pipe limited in a hollow cavity, magnetic steel I, a valve plate and magnetic steel II arranged at the top of the activating plate as well as a tension spring arranged between the activating plate and the bottom plate. The mutual and electric double-controlled baffle type one-way overspeed shutoff valve is characterized in that the manual operation assembly comprises a manual rotating shaft limited at the oil outlet, a manual shifting plate arranged on the manual rotating shaft and a handle which is arranged outside the casing and can control rotation of the manual rotating shaft; a flow speed adjusting device is arranged in the hollow cavity; a steel block is arranged on the inner wall, close to the oil outlet, of the cavity. The problems that the closing flow speed threshold value of existing overspeed shutoff valves are difficult to adjust, false alarm is easily caused, bouncing is easily caused when the valve plate is closed and the like are fundamentally solved, and the one-way overspeed shutoff valve has the advantages of convenience in use, safety, reliability, high accuracy and the like.
