Abstract

The invention discloses a multifunctional fire extinguishing device which can synchronously eject double fire extinguishing media. The fire extinguishing device consists of driving power devices, fire extinguishing medium storage tank devices and an ejecting device. According to the fire extinguishing device, a manner that two kinds of fire extinguishing media are synchronously ejected, or a manner that one kind of the fire extinguishing media is ejected can be selected; the ejecting flow and the ejecting strength of double fire extinguishing media or single fire extinguishing medium can be synchronously controlled through valves; a dry-powder fire extinguishing agent medium can be ejected far by the power of ejecting a water-series extinguishing agent medium or foam extinguishing agent medium. The fire extinguishing device is simple and practical, has a powerful flexible fire extinguishing capability, and can be widely applied and equipped in various fire extinguishing systems or fire extinguishing equipment; the flow of the double-media multifunctional fire extinguishing device can be flexibly controlled, and complicated mixed fires can be effectively put out.

Description

technical field [0001] The invention belongs to the field of fire extinguishing devices and relates to a multifunctional fire extinguishing device which sprays double fire extinguishing media. Background technique [0002] With the development of economy and society, a large number of flammable composite materials are used in the construction of various facilities, and the fires that occur are generally complex three-dimensional mixed fire scenes. Traditional fire trucks, fire tanks, fire guns, fire sprinkler systems and other fire extinguishing devices and fire extinguishing systems can only spray one kind of fire extinguishing medium, which has great limitations, such as spraying water, water system fire extinguishing agent, foam type Fire extinguishing agent, dry powder fire extinguishing agent, gas fire extinguishing agent, etc.; in addition, when the sprayed fire extinguishing medium is a dry powder fire extinguishing medium, due to the small particles and light weight,...
