全上問題があった。2. Description of the Related Art Conventionally, to discharge water from a fire hydrant or fire extinguishing water located away from a fire site, a plurality of pump devices such as fire pump trucks are connected in series with a relay hose and connected to a water supply source. Water may be sent from the starting pump device to the terminating pump device by operating the pump device of each fire pump car, but water is sent while mutually communicating the discharge pressure of each pump device and adjusting it appropriately. If not, the water pressure will fluctuate and sudden pressure fluctuations will occur at the start and stop of water discharge, resulting in excessive water pressure on the equipment. There was a problem above.

ある。Therefore, as shown in FIG. 3, a fire pump and a water supply source 20 such as fire extinguishing water are connected to a fire pump car 21 by a water supply hose 22, and the fire pump car 21 is connected.
The tank tank with pump 23 is connected with a relay hose 24, and the water supplied from the fire fighting pump truck 21 is connected to the tank truck with pump 2
The water in the tank tank with pump 23 is stored in the tank tank with pump 23 by a relay hose 27 that connects the tank tank with pump 23 and the water tank 26 installed near the water discharge pump vehicle 25.
Water to the water tank, and the water stored in the water tank 26 is discharged into the pump car 2
5 is sucking and releasing water. Therefore, the number of tank tank trucks with pumps 2 for relaying depends on the distance between the fire site and the water supply source.
3 and the fire fighting pump car 21 and the water discharge pump car 25 are required, and the water tank 26 has to be transported and installed in the vicinity of the water discharge pump car 25, and it takes time to set up and quick fire fighting activities cannot be performed. There is a problem, and there is a problem that a sufficient amount of water discharge cannot be obtained unless the water tank 26 is enlarged.

However, it is difficult to adjust the discharge pressure of multiple pumps in a well-balanced manner, and there is a time lag between the pump adjustment and the discharge pressure change. There is a problem that the pump cannot be surely dealt with, and when the water in the water tank 26 or the tank is exhausted and air is sucked in, or the pump is excessively pressured due to a rapid pressure fluctuation due to a fluctuation of the water discharge amount, a water discharge start, or a water discharge stop. In addition, there is a safety problem because fire fighters may fall due to recoil due to fluctuations in water pressure of the water discharge hose 28.

がない。With such a construction, when the fire site is far from the water supply source, a plurality of fire pump cars are sequentially arranged in series from the water supply source 2 toward the fire site and connected by the relay hose. When the water supply pump device 1 which is a fire fighting pump device is connected to the water supply source 2 to supply water, the water of the water supply source 2 sucked by the water supply pump device 1 and the relay pump device 4 connected to the water supply pump device 1 The water is sent to the water discharge hose 16 through the water discharge pump device 13 connected to the relay pump device 4, and the water is discharged to the fire site away from the water supply source 2. The relay pump device 4 and the water discharge pump device 1 are used.
Since the relay hose on the suction side of 3 is provided with the control valve 5 for adjusting the pressure on the input side according to the pressure on the output side, even if water is supplied at a high pressure of about 5 to 14 kgf / cm 2 Also, the pressure on the suction side of the relay pump device 4 and the water discharge pump device 13 is controlled to be within 0 to 3 kgf / cm 2 . That is, if the discharge pressure of the feed water pump device 1 or the relay pump device 4 fluctuates, the piston valve 10 of the control valve 5 approaches the valve seat 12 against the spring force of the spring 11 to reduce the inflow amount and input. The rise in pressure on the side is suppressed, and even if water is supplied at high pressure, the relay pump device 4,
No excessive pressure is applied to the suction side of the water discharge pump device 13.

ポンプ装置１３の吸引側の圧力は規定圧に保たれる。In addition, when the water discharge amount of the water discharge pump device 13 changes or a sudden pressure change occurs due to the start or stop of water discharge, the output side connection port 8 of the control valve 5a between the water discharge hose 16 and the relay hose 15 is formed. Since the piston valve 10 comes into contact with and separates from the valve seat 12 against the spring force of the spring 11 by the increase or decrease in the pressure of the nozzle 11, the nozzle 1 of the water discharge hose 16 is adjusted.
The pressure of 6a is kept substantially constant. As a result, the pressure on the discharge side of the water discharge pump device 13 fluctuates, but the piston valve 10 causes the spring force of the spring 11 to increase due to the increase / decrease in the pressure of the output side connection port 8 of the control valve 5 provided on the suction side of the water discharge pump device 13. Since the inflow amount is adjusted by contacting and separating from the valve seat 12 against the pressure, the pressure on the suction side of the water discharge pump device 13 is maintained at a specified pressure.

Since the suction side is connected to the water supply source 2 in which water for fire extinguishing or the like is stored, the pressure on the suction side of the water supply pump device 1 does not exceed the specified value. Therefore, the water supply pump device 1, the relay It is not necessary to adjust the driving force of each pump device while mutually communicating the discharge pressures of the pump device 4 and the water discharge pump device 13.

で便利である。In particular, as in the embodiment, the tubular main body 9 has one end as the input side connection port 7 connected to the relay hose and the other end as the output side connection port 8 connected to the suction side of the fire pump device. A cylindrical piston valve 10 having a pressure-receiving surface at the output-side opening end expanded from the pressure-receiving surface at the input-side opening end is slidably mounted on the output side by a spring 11 in a state that it is normally elastically urged to the output side. In both cases, the control valve 5 is provided with a valve seat 12 facing the output side opening of the piston valve 10 on the input side in the tubular body 9.

Pump device and to the required to be interposed between the fire pump apparatus
The number of fire fighting pump devices is used as a relay pump device.
Are connected in series by a relay hose, and the relay pump device
Since the control valve that adjusts the pressure on the input side according to the pressure on the output side is provided on the suction side and the suction side of the water discharge pump device to adjust the pressure fluctuation, it is possible to change the amount of water discharge, start water discharge, or discharge water. There is no excessive pressure on the equipment due to stoppage, and it is possible to eliminate the accident that the firefighters fall due to the reaction caused by the rapid change in the water discharge pressure. Since it is not necessary to adjust the driving force of each pump device by communicating with each other, the operation is extremely simple, and since the amount of water supply can be stabilized, air is not sucked in and sudden pressure fluctuations do not occur. There is also no danger to firefighters due to the recoil caused by such pressure fluctuations. Furthermore, unlike conventional equipment, devices such as pump cars with tanks and water tanks are no longer needed, so the system configuration is simple and easy, and long-distance water supply that supplies water from a water supply source located in a place away from the fire site to the water discharge pump device. It is then possible to extinguish the fire. Therefore, the present invention is of great practical value as a relay type water supply device for fire fighting, which solves the conventional problems.
