Abstract

PROBLEM TO BE SOLVED: To prevent trouble for the hosing of water even when a hose is compressed by a heavy vehicle while water is hosed for extinguishing a fire by fitting a device for regulating water pressure by hosing water corresponding to excess-water pressure in the middle of the hose extended through a fire pump onto the surface of road. SOLUTION: In the middle of fire hoses 3a and 3b, a female screw metal fixture 2a is attached at the terminal part of a body 1 and a male screw metal fixture 2b is attached at the other terminal so that the metal fixture hoses 3a and 3b for screw are respectively screwed. A base frame 5 is formed by fitting a bottom plate 4c through frame poles 4a and 4b under the body 1, and the body 1 is held separately from the surface of road. Inside the base part of the base frame 5, links 7a and 7b are wound, and a handle 8 is fitted freely movably from side to side. Water release holes 9a are opened on the front and rear side faces of the body 1 between the links 7a and 7b, and open/close lids 10a are hinged through narrow pressure springs 13a to the respective holes. Thus, when the hoses 3a and 3b are compressed by the heavy vehicle, the open/close lids 10a and 10b are opened and discharge water and when the compression is canceled, the open/close lids 10a are closed so that water is discharged again for extinguishing the fire.
