Claims

[Scope of Claim for Utility Model Registration] (1) A valve that is attached to a reel that winds up and stores a fire hose and has a pipe arranged to lead water from a water supply port provided on a wall etc. to the hose. , the pipe is composed of a water supply port side pipe and a hose side pipe, the hose side pipe is rotatably connected to the water supply port side pipe, and the valve stem is connected to the hose side pipe so as to rotate as the hose side pipe rotates. An automatic valve for a fire hose reel, characterized in that a valve is attached to the valve stem, which closes the flow path of the pipe when the hose is wound onto the reel, and opens the flow path when the hose is pulled out from the reel. (2) A male thread is provided on the valve stem, a hollow cylindrical member having a female thread that is screwed into the male thread is fixed in the water supply port side pipe, and the valve stem is attached to the hollow cylindrical member in such a manner that the male thread is located within the hollow cylindrical member. When the hose is wound onto a reel, the valve closes the opening of the hose side pipe, and when the hose is pulled out from the reel, the valve rod is displaced in the direction of the rotation axis by the screwing of both screws. 2. The automatic valve for a fire hose reel according to claim 1, wherein the valve is separated from the opening of the hose side pipe.
