とを特徴とする減圧弁における真空破壊装置。 A vacuum breaking device that is attached to a pressure reducing valve in which a main valve port that communicates between a primary side and a secondary side is controlled to open and close by a main valve body that is linked to a diaphragm that responds to pressure changes on the secondary side. A partition is provided inside the cylindrical cap body, a valve rod is inserted through the center of the partition so as to be slidable up and down, and a sufficient opening area is provided in the partition with the sliding support of the valve rod as the center. A ventilation hole is installed through the valve, and a valve seat is installed around the ventilation hole on the upper surface of the partition wall on the installation side, and a valve body that attaches to and separates from the valve seat is installed at the upper end of the valve stem. At the same time, 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, and such a vacuum breaking device is installed on the primary side and the secondary side, respectively, with the chuck valve body in between. A vacuum breaking device for a pressure reducing valve, characterized in that it is equipped with a vacuum breaking device.
