Description

  The present invention relates to fire fighting equipment.

In general, in a fire fighting system applied to a building or the like, water supply to a discharge device such as a sprinkler or an indoor fire hydrant is performed at a pressure and a water supply amount required by the discharge device farthest from the pressurized water supply device. For this reason, in a general fire fighting system, water supply to discharge devices other than the discharge device farthest from the pressurized water supply device is performed with excessive pressure and water supply amount. Therefore, in general fire fighting systems, when fire extinguishants such as water and aqueous foam are discharged from a discharge device other than the discharge device farthest from the pressurized water supply device, water loss (the discharged fire extinguisher is excessive pressure) And secondary damage due to excessive amounts).
Therefore, conventionally, the water supply pressure in the pipe is detected in order to supply the discharge device with a pressure / amount of water according to the installation location, and the rotation speed of the drive device that drives the pump is determined based on the detected pressure.

Released. When water is discharged from the sprinkler (SP) and the elevated water tank 3 alone cannot fill the primary side pipe and the secondary side pipe with water, the pressure of the primary side pipe and the secondary side pipe is lowered. When the pressure of the secondary side pipe decreases to a predetermined pressure, a signal is transmitted to the control device 5 from the pressure switch 2 provided for the fourth-floor sprinkler (SP). When the control device 5 receives a signal from the pressure switch 2 provided for the fourth-floor sprinkler (SP), the control device 5 discharges water based on the received signal (here, the fourth-floor sprinkler (SP) )) Is specified. The control device 5 uses a pressure (here, 4th floor) where the specified sprinkler (SP) is installed from the pressure water supply table (FIG. 2) stored in the recording means. Then, BMP) and the amount of water (1 (circled number) L / min) are read out. The control device 5 transmits a pressure control signal / water supply amount control signal based on the read pressure / water supply amount to the pressurized water supply device 4. The pressurized water supply device 4 uses the water from the expiratory water tank 6 to transmit the water from the fire extinguishing water tank 8 to the sprinkler (SP) on the fourth floor. At that time, the pressure control signal received from the control device 5 Based on the water supply amount control signal, the pressure and amount of water supply are controlled. As a result, in the first embodiment, the water supply pressure and the water supply amount from the pressurized water supply device 4 are maintained at BMPa and 1 (circled number) L / min, respectively.
Note that the pressure drop in the primary side pipe can occur due to leakage of fire extinguishing material from the pipe due to aging of the pipe even when no fire has occurred. As described above, when the pressure of the primary side pipe decreases due to a cause different from that of the fire, a predetermined signal is transmitted from the pressure switch 2 to the control device 5. When the control device 5 receives the signal from the pressure switch 2, the control device 5 operates the pressurized water supply device 4 to maintain the pressure of the primary side pipe at a predetermined pressure.

Therefore, according to this pressure water supply amount table, water can be supplied from the pressurized water supply device 4 at a pressure and water supply amount that are optimum for the type and installation location of the discharge device.
The values A to W in FIG. 2 can be calculated by, for example, pressure loss calculation, but the present invention does not limit the calculation method of the values A to W to pressure loss calculation. Therefore, the values A to W may be anything as long as they indicate the optimum pressure for each type of discharge device. Accordingly, the values of A to W may be the same value or all different values, for example, as long as they indicate the optimum pressure for each type of discharge device. Some of A to W may have the same value.

In this case, the control device 5 receives the signal from the pressure switch 2 and the signal from the activation push button, and identifies the discharge device that is discharging water based on the received signal. The control device 5 determines the type and installation location of the specified discharge device (here, type: foam discharge device (F) + sprinkler (SP) + indoor fire hydrant device ( X), installation location: 2nd floor), and the pressure and water supply amount determined in advance are read out.
