Abstract

Provided is a pressure control system for fire extinguishing equipment, the system including: valves installed at pipes for receiving water supplied from a fire-extinguishing water tank; a digital indicator configured to measure water pressure of the valves or water pressure of the pipes in which the valves are installed and to transmit a signal for abnormality when a value of the measured water pressure does not correspond to a predetermined range; a main control unit configured to transmit a signal for pressure reduction intended for reducing the water pressure of the valves when the signal for abnormality is received from the digital indicator; and a motor operating valve (MOV) installed at the pipes or the valves and configured to reduce the water pressure when the signal for pressure reduction is received.

Claims

1. A pressure control system for fire extinguishing equipment, which measures water pressure of pipes of the extinguishing equipment to open and close valves according to the measured water pressure, the system comprising:

valves installed at pipes for receiving water supplied from a fire-extinguishing water tank;

a digital indicator configured to measure water pressure of the valves or water pressure of the pipes in which the valves are installed and to transmit a signal for abnormality when a value of the measured water pressure does not correspond to a predetermined range;

a main control unit configured to transmit a signal for pressure reduction intended for reducing the water pressure of the valves when the signal for abnormality is received from the digital indicator; and

a motor operating valve (MOV) installed at the pipes or the valves and configured to reduce the water pressure when the signal for pressure reduction is received.

2. The system of claim 1, wherein the digital indicator measures water pressure of a pipe on a first side corresponding to the pipe arranged at the fire-extinguishing water tank and water pressure of a pipe on a second side corresponding to the pipe arranged at an opposite side of the first side.

3. The system of claim 1, further comprising:

an integrated monitoring control unit for fire-fighting equipment configured to display an abnormal condition generated from the pipes by the main control unit when abnormality is generated from the pipes.

4. The system of claim 1, wherein the main control unit receives, from each measurement sensing unit, information on the existence of abnormality in the fire-extinguishing water tank on the amount of fire extinguishing water, information on the existence of abnormality in a fire extinguishing equipment pump, information on the operation of a smoke removing fan of a vestibule, information on the operation of storm and flood pumps for fire-fighting equipment or information on the opening and closing conditions of smoke ventilators for each floor.

5. The system of claim 4, wherein the integrated monitoring control unit for the fire-fighting equipment displays the information on the existence of abnormality in the fire-extinguishing water tank on the amount of fire extinguishing water, the information on the existence of abnormality in a fire extinguishing equipment pump, the information on the operation of a smoke removing fan of a vestibule, the information on the operation of storm and flood pumps for fire-fighting equipment or the information on the opening and closing conditions of smoke ventilators for each floor according to control of the main control unit.

6. The system of claim 3, further comprising a mobile terminal connected to the integrated monitoring control unit via a WI-FI zone or a 3G or 4G network and configured to receive text messages for an alarm situation, to monitor fire-fighting equipment and to execute remote control or an alarm check.

7. The system of claim 1, further comprising a telegraphic repeater configured to receive the signal for abnormality from the digital indicator and to transmit the received abnormal signal to the main control unit.

8. The system of claim 7, wherein the telegraphic repeater performs communication via an RS232 or RS485 method or an internet method.

9. The system of claim 1, wherein the valves may be configured of a pressure reducing valve or an alarm valve.
