Abstract

The invention discloses a novel multifunctional fire protection coaxial nozzle device used for spraying two kinds of fire extinguishing media at the same time. The novel multifunctional fire protection coaxial nozzle device can selectively spray two kinds of fire extinguishing media at the same time or spray one kind of fire extinguishing media, the spraying flow and intensity of the two kinds of fire extinguishing media or one kind of fire extinguishing media are controlled through a valve at the same time, and spraying power of water extinguishing agent or foam extinguishing agent media enables dry powder fire extinguishing agent media to be sprayed by a longer distance. The novel multifunctional fire protection coaxial nozzle device is simple and practical, has high and flexible fire extinguishing capacity, and can be widely applied to and arranged into various fire extinguishing systems or fire extinguishing devices.

Description

technical field [0001] The invention belongs to the field of fire-fighting and fire-extinguishing systems, and relates to a multi-functional coaxial nozzle device for spraying multiple fire-fighting and fire-extinguishing media at the same time. Background technique [0002] At present, various fire extinguishing devices such as fire trucks, fire tanks, fire guns, and fire sprinkler systems, and the fire extinguishing medium nozzle device in the fire extinguishing system can only spray one kind of fire extinguishing medium, which has great limitations, such as spraying water, water system, etc. fire extinguishing agent, foam 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, because of the small particles and light weight, it is impossible to carry out long-distance spraying. Or the firefighting equipment cannot be at a safe dista...
