The operation principle of Multipurpose ultrahigh-pressure foam fine mist fire-fighting equipment described in the utility model:
A, startup displacement pump form negative pressure, by water and foam dope intake line between displacement pump entrance and water inlet and foam dope entrance; Water, from the water inlet filter of flowing through, filters out the foreign material in water, and protection displacement pump is not damaged, then the check valve I of flowing through, and anti-sealing and foam mixing liquid flow back to water source, and water enters into Multipurpose water and chemicals blender after by check valve I; Foam dope flows into check valve II from foam dope entrance, check valve II prevents that water from flowing to foam dope storage bin, foam dope flows to stop valve again, (use water as fire extinguishing as made separately and can close stop valve), then arrive Multipurpose water and chemicals blender by needle-valve, the effect of needle-valve (9) is the mixed proportion that regulates foam dope and water;
B; Water and foam dope Multipurpose water with in chemicals blender, mix after, the mixed liquor displacement pump of flowing through again, mixed liquor is pressurized to 5-30MPa by displacement pump;
C, high pressure mixing liquid flow into relief valve, the effect of relief valve is that control system pressure is not higher than setting value, when high pressure mixing liquid lower than when setting value relief valve a-b port through-flow, when high pressure mixing liquid higher than when setting value relief valve a-c and a-b port simultaneously through-flow, when a-c port is through-flow, part high pressure mixing liquid is back to displacement pump inbound port, make high pressure mixing hydraulic control at b port below design load, the high pressure mixing liquid of b port flows to threeway;
D, three-way connection one end are connected to accumulator, and one end is connected to spray gun valve, and in the time of spray gun valve open, high pressure mixing liquid flows to nozzle, through nozzle ejection super-pressure foam;
The operation of E, impulse jet is to realize by switch spray gun valve, and the frequency of pulse is to control by opening and closing spray gun valve; In the time of spray gun valve closing, mixed liquor or water can flow to accumulator, exceed when setting value when the pressure of accumulator boosts, and relief valve a-c can open, and this makes mixed liquor or water by being back to displacement pump, remaining on pressure is set; When spray gun valve opening, the mixed liquor or the water that are stored in accumulator can produce super-pressure foam or thin water smoke by high velocity stream delivery nozzle; Circulating open close spray gun valve just can produce impulse jet, and the switch control of spray gun valve can be used manual or electronic or pneumatic or surge.
