ことを特徴とする減圧弁における真空破壊装置。 A vacuum breaking device attached to a pressure reducing valve, the opening and closing of which is controlled by a main valve body interlocking with a diaphragm that responds to pressure changes on the secondary side, and a main valve port that communicates between the primary side and the secondary side. A partition is provided inside the cylindrical cap body which is removably screwed onto the valve box, and a valve rod is inserted through the center of the partition so as to be slidable up and down, and the sliding support part of the valve rod is inserted into the center of the partition. A ventilation hole with a sufficient opening area is provided through the partition wall, and a valve seat is provided around the ventilation hole on the top surface of the partition wall, which is the side that is attached to the valve box. A valve body that attaches to and separates from the valve seat is attached to the upper end, and a spring that presses the valve body in the valve closing direction is press-fitted between the lower end of the valve rod and the lower surface of the partition wall. Vacuum breaking device in pressure reducing valve.
