ピストン式の消火栓バルブ１２に連結している。 FIG. 1 shows an embodiment in which the fire hydrant valve of the present invention is applied to a fire hydrant of the type in which a hose is wound around a reel and stored in a storage box.
2 is a door, and 3 is a rotating means for changing the hose 4 to a predetermined direction. This rotating means 3 includes a connecting rod 5 whose lower end is pivotally attached to the wall surface of the box 1, a support shaft 6 supported by the tip of the connecting rod 5, and a base portion of which is rotated by the shaft 6. It consists of a freely supported plate member 7. Reference numeral 8 denotes a plucked strip provided on the support shaft 6, which allows the plate member 7 to be elastically opened with respect to the connecting rod 5. Reference numeral 9 denotes a reel around which the hose 4 is wound, and as shown in FIG. 2, the two hoses 4 folded in half are each wound separately. Reference numeral 10 denotes a connecting portion that connects two hoses 4. A water discharge nozzle 11 is attached to the tip of one hose 4, and the rear end of the other hose 4 is connected to a piston-type fire hydrant valve 12.

始動スイツチである。 This fire hydrant valve 12 includes an L-shaped outer pipe 14 connected to a water supply port 13, and a cylindrical portion 15 of this outer pipe 14.
The valve is composed of an inner tube 16, a portion of which is slidably fitted into the inner tube, and is opened and closed by sliding the inner tube 16. The outer tube 14 has a claw portion 17 biased by a spring (not shown) on the inner surface of the opening end on the side of the water supply port 13, and is rotatably fitted into the water supply port 13 via the claw portion 17. There is. On the other hand, since the inner tube 16 has its tip connected to the base of the hose 4, by pulling the hose 4, the inner tube 16 slides and opens the valve. 18 is an O-ring. 19 is an alarm switch disposed in the storage box 1, and 20 is a pump start switch.
火災が発生した場合、消火員は、まず扉２を開

ことができる。 Next, when the water spray nozzle 11 is removed and the user heads toward the fire point, the hose 4 is unwound from the reel 9 in that direction, and the fire hydrant valve 12 changes direction following the extending direction of the hose 4. When the hose 4 is fully extended and pulled, the inner pipe 16 connected to the base of the hose 4 slides as shown in FIG. 4, and the fire hydrant valve 12 opens. Thereby, water is passed toward the water spraying nozzle 11, and water spraying work can begin. In this way, extinguishing operations can be carried out quickly and smoothly by one firefighter.

とができる。 As described above, according to the fire hydrant valve of the present invention, when the main valve is opened in advance and the nozzle is carried toward the fire scene, the outer pipe changes its direction to follow the extending direction of the hose. Because you can
The valve opening operation can be easily performed.
Furthermore, when the hose is pulled by holding the nozzle, the inner tube slides and opens the flow path in the outer tube. Therefore, all operations can be carried out by a single fire extinguisher, so fire extinguishing activities can be carried out quickly in an emergency.
