プリンクラー用給水配管装置。 A high-pressure air tank that communicates with the water supply pipe at a position near the branch end is installed in the middle of a sprinkler water supply pipe that is branch-connected to a water pipe, on-off valves located on the upstream and downstream sides of the air tank, and the air tank and the upstream on-off valve. A check valve located between the air tank and the downstream opening/closing valve is provided, and the spool valve has elasticity in the direction of always moving the spool that opens and closes the water supply pipe to the open position. A water supply piping device for a sprinkler that is formed by providing a pressure chamber at the end of the spool that presses and holds the spool in a closed position using downstream pressure.
