Abstract

The invention provides a new froth fire extinguishing system, which solves the technical problem that the foam concentrate used in the exiting froth fire extinguishing system is non-alcohol type foam concentrate, and the foam concentrate fails to put out the fire caused by water-soluble flammable liquid. The invention comprises a case and a foam concentrate tank (1) arranged in the case, a foam concentrate sucker (2), a foam concentrate control valve (3), a check valve (4), a foam concentrate proportioner (5), a flow pipe (8), a flow pipe control valve (6) and a coupling hose (9); the foam concentrate in the foam concentrate tank (1) is gel-type alcohol-type fire foam. The new froth fire extinguishing system has the advantages of effectively putting out the fire caused by both alcohol-type flammable liquid and non-alcohol type flammable liquid.

Description

technical field [0001] The invention relates to a fire fighting equipment, in particular to a foam fire extinguishing system. Background technique [0002] The foam fire extinguishing system has a centralized system and a distributed system. The centralized system is easy to manage. However, for the long tunnel of the expressway, due to the long fire water supply pipeline and foam pipeline, when a fire occurs, there is a need to start the fire extinguishing system to spray foam to extinguish the fire. If the time is long, the effective fire extinguishing time will be delayed, and a large amount of foam mixture will remain in the pipeline after fire extinguishing, which will cause waste; the decentralized system is to install a foam fire extinguishing box at each fire hydrant in the tunnel, and foam fire extinguishing water supply pipes The net is used together with the fire hydrant water supply pipe network system. When extinguishing the fire, the foam liquid will not enter ...
