PLC intelligent double control firefighting pressurization pressure-stabilizing water supply device

Provided is an intelligent double control firefighting pressurization pressure-stabilizing water supply device. Running of a pressure-stabilizing water pump and an air compressor is respectively controlled by utilizing control signals collected by a liquid level float valve arranged on an air pressure water tank and an electric contact pressure gauge through a PLC intelligent control cabinet, the air pressure ratio in the water tank is controlled strictly by the double control effect, gas is supplemented when lacked, the regulating water quantity is increased, and the regulating water quantity during a firefighting period is guaranteed. Compressed gas in the tank is effectively prevented from entering a pipe network and having the reaction of combustion supporting during the power outage and water supply stopping period of the device due to the arrangement of air stopping valves in the tank. The whole device detects pressure of the air pressure water tank, the water volume and water level conditions of a water box through PLC centralized control, corresponding water supply parameters are displayed and set and water supply records are inquired on a touch screen, and the intelligent double control firefighting pressurization pressure-stabilizing water supply device has stability in control and convenience in management, saves energy, performs control in a more standard mode, runs distinctly, is low in failure rate and is always in an ideal state.
