Claims

[Claims for Utility Model Registration] (1) A housing having a flow path between an inlet and an outlet, a fixed valve seat within this housing, and a movable valve seat that can come into close contact with and detach from the fixed valve seat;
a diaphragm that movably attaches the movable valve seat with respect to the housing; and a first diaphragm that urges the movable valve seat to always bring the movable valve seat into close contact with the fixed valve seat.
a biasing means, a valve body that can come into close contact with and detach from the movable valve seat on the same side as the side on which the movable valve seat comes into close contact with the fixed valve seat, and this valve body is brought into close contact with the movable valve seat at all times. and a stopper that limits the amount of movement of the valve body toward the movable valve seat, so that fluid pressure exceeding a predetermined value entering from the inlet of the housing acts on the diaphragm. When pressed, the movable valve seat is disengaged from the fixed valve seat and is also disengaged from the valve body stopped by the stopper, thereby opening the valve, the relief valve further comprising: A relief valve comprising an electric valve opening device and a manual valve opening device that can be forcibly separated from the movable valve seat to open the valve. (2) The housing is divided into a first half section including the inlet and a second half section including the outlet, and the second half section is detachable from the first half section. and in the second half, the fixed valve seat, the movable valve seat, the diaphragm,
The relief valve according to claim 1, wherein the first biasing means, the valve body, the second biasing means, the stopper, and the manual valve opening device are integrated in advance. . (3) The relief valve according to claim 1 or 2, wherein the manual valve opening device also functions as a stopper for the valve body.
