<p>PURPOSE: A fire equipment pressure control system is provided to indicate the pressure condition of the pipe of fire equipment, and to prevent a leakage by overpressure in the pipe from the pipe, an indoor fire hydrant angle valve, and a sprinkler (the valve, head, and end), etc. CONSTITUTION: A fire equipment pressure control system measures the water pressure of the pipe, and open and close the valve according to the measured water pressure. The fire equipment pressure control system comprises: a valve installed in the pipe transmitting and receiving from the fire fighting water tub (130); a digital indicator measuring the water pressure of the valve or the pipe in which the valve is installed, and transmitting out of phase signal if measured water pressure value does not fall under the pre-set range; a main control part transmitting depression signal to depress the water pressure of the valve in case of receiving the out of phase signal from the digital indicator; and a motor operating valve which is installed in the pipe or the valve, and operates and depresses the water pressure in case of receiving the depression signal.</p> |
