逃し弁における手動開閉装置。 The valve stem 4a of the pressure reducing valve 40 that opens and closes communication between the primary side The outer ends of the valve stem 4a are connected so as to be freely detachable, and a relief valve 30 and a relief valve seat 31 are connected to the outer end of the valve stem 4a and the pressure sensitive plate 2. A pressure reducing spring 42 is connected to the pressure sensitive plate 2, and a relief spring 3 is connected to the valve stem 4a.
In the pressure reducing/relief valve formed by connecting the two valves, the movable range of the relief valve 30 assembled to the pressure sensitive plate 2 toward the closing side is controlled by the relief valve seat 31 assembled to the outer end of the valve stem 4a. A stopper S that restricts the movable range to be narrower is provided in the valve box 1, and an operating member L that forcibly moves the relief valve seat 31 in the direction of separating it from the relief valve 30 is installed in the valve box 1. Reduced pressure
Manual opening/closing device in relief valves.
