SMART NON-POWERED AUTOMATIC FOAM FIRE EXTINGUISHER CAPABLE OF MINIMIZING COMSUMPTION OF AQUEOUS FOAM SOLUTIONS AND FIRE SUPPRESSION SOLUTIONS

摘要

PURPOSE: A smart non-powered automatic foam fire extinguisher is provided to reduce initial investment cost and rapidly mix aqueous foam solutions with air by operating using compressed air without power supply.;CONSTITUTION: A smart non-powered automatic foam fire extinguisher(100) comprises an aqueous foam solution reservoir, a compressed air container(120), a first valve(130), an aqueous foam solution supply line(140), a second valve(150), and an air injection holder(160). The compressed air container is connected to the aqueous foam solution reservoir in order to supply compressed air. The aqueous foam solution supply line supplies aqueous foam solution discharged from the aqueous foam solution reservoir to a nozzle(300). The second valve is installed in back end of the aqueous foam solution reservoir and controls discharge of the aqueous foam solution by opening and closing the valve. The air injection holder comprises an orifice which controls flow amount of the aqueous foam solution supplied from the aqueous foam solution supply line, an air amount control unit(190), and a body which is connected to the nozzle.;COPYRIGHT KIPO 2012
