Open system working principle:
In the quasi-working condition, high-pressure water mist fire extinguishing system from the pump group outlet to the regional valve in front of the pipe network, to maintain a certain pressure, when the pressure is lower than the pressure regulator pumps set to start the pressure, regulator pumps to start, so that the system network to maintain a stable pressure, when the regulator pumps run for more than a certain period of time after the pressure is still less than, the main pump will be started, the regulator pump stops. Equipment regulating water tank inlet is equipped with water replenishment solenoid valve, water through the filter and water replenishment solenoid valve into the water tank; water tank is equipped with a liquid level controller to achieve automatic control of the water level of the water tank.
