(For example, see Japanese Patent Publication No. 54-16156, Japanese Patent Publication No. 62-102774, Japanese Utility Model Publication No. 1-155462, and Japanese Patent Laid-Open No. 3-251266).

These devices have a mechanism for adjusting the water supply pressure and the water supply amount by rotating the pump of the pump device provided in the fire engine and opening / closing the water stop valve of the water discharge port. It is a device that can control pressure only to one line of fire hose wire for one outlet.

From this, a fire extinguisher extension system of one system extended from one water discharge port (2) of the pump device (1) provided in the fire engine by using the two-way branch fitting (16) for manual fire fighting. When branching the source line (3) into the two lines of fire extinguishing hose lines (4) and (5) for water discharge work, the pump rotation of the pump device equipped in the fire engine and the stop valve of the water stop Only by adjusting the water pressure and water flow by opening and closing, etc., the branched fire extinguishing hose wires (4) and (5) and the pipes (11) and (12) at the end of the fire extinguishing hose can be used. At the same time, the same change in water supply pressure and water supply amount will occur.

Therefore, it is necessary to remotely and individually adjust the water discharge amount of each of the two lines of the fire-extinguishing hose wires (4) and (5) that are branched by using the two-way branch fitting (16) for manual fire fighting. I can't.

Up to now, one line of the fire extinguishing extension hose wire (3) has been branched to the two lines of the fire extinguishing hose wires (4) and (5) by using a two-pronged branch fitting (16) for manual fire fighting. When water is discharged by using the fire extinguishing hose wires (4) and (5) as shown in FIG. In order to obtain the water discharge amount, the manual fire extinguishing water discharge ports (23), (24) of the two systems of the manual fire fighting bifurcating metal fitting (16) corresponding to each fire extinguishing hose wire (4), (5) are used. It is necessary to open and close the water shutoff valves (17) and (18), and the other workers are instructed to do this manually.

Therefore, the effective water discharge amount required by the worker in charge of water discharge at the pipe sections (11) and (12) at the ends of the branched bifurcating fire hose wires (4) and (5) is set. It will take a considerable amount of time to obtain it, and each worker will need another worker.
