BRANCHING DEVICE FOR FIRE-FIGHTING HOSE

摘要

PROBLEM TO BE SOLVED: To provide a branching device for fire-fighting hose, with which the flow rate and water pressure of a fire-fighting hose for using pressurized water supplied from a single water supply source while branching it to a plurality of water flows can be prevented from being rapidly fluctuated by the operation of the partial fire-fighting hose. SOLUTION: When pressure in a water supply destination side partitioned chamber connected to a plurality of water supply destinations is changed from a desired numerical value, a main valve is moved and the supply of pressurized water from a water supply source side partitioned chamber to the water supply destination side partitioned chamber is controlled for conducting or cutting off the water supply source side partitioned chamber and the water supply destination side partitioned chamber.
