出防止装置。[Scope of Claim for Utility Model Registration] 1. A valve box having a lower opening communicating with the inside of the water pipe is installed in the upper part of the water pipe, and a ventilation hole is provided in the center of the upper wall that closes the upper part of the valve box. In the air valve, a float is provided in the valve box so as to be movable up and down, and a holding member with openings at the upper and lower ends of the float is provided at a position facing the vent hole, and a valve body that opens and closes the vent hole is mounted with the holding member. A device for preventing discharge of pipe water in an air valve, characterized in that the air valve is held movably in the up and down direction with a play smaller than the up and down stroke of the float. 2. An air valve in which a valve box having a lower opening that communicates with the inside of the water pipe is installed in the upper part of the water supply pipe, and a vent hole is provided in the center of the upper wall that closes the upper part of the valve box, wherein the valve box A cylindrical floating valve body whose upper end is closed by the upper wall and whose lower end is open is opened and closed by the buoyancy of water flowing into the valve box from the lower opening through a guide member. A second ventilation hole is provided in the center of the upper wall of the floating valve body, and a float is provided below the floating valve body in the valve box so as to be movable up and down. A holding member with openings at the upper and lower ends is provided at a position facing the second vent hole of the valve body, and the holding member is used to move the valve body that opens and closes the second vent hole in the vertical direction with a play smaller than the vertical stroke of the float. A device for preventing discharge of pipe water in an air valve, characterized in that it is movably held.
