し弁における手動開閉装置。 A valve body 3 is attached to a pressure sensitive plate 2 installed in the valve body body 1a so as to operate by sensing the pressure in the secondary chamber w, and an annular valve seat facing a seat 30 made of an elastic material provided on the valve body 3. 4 is assembled to the valve box main body 1a so as to be movable in the direction in which the valve body 3 is actuated by the actuation of the pressure sensitive plate 2, and the annular valve seat 4 is attached to a spring weaker than the spring 5 connecting the pressure sensitive plate 2. A stopper 9 is pushed toward the valve body 3 by a spring c set at a pressure to restrict the movable range Z of the valve body 3 toward the closing side to be narrower than the movable range y of the valve seat 4.
A manual opening/closing device for a pressure relief valve, characterized in that the annular valve seat 4 is connected to an operating member L that moves the valve seat 4 in a direction to separate it from the valve body 3 by manual operation.
