Description

(1) Technical field

[0001] The invention relates to a fine water mist fire extinguishing nozzle used in naval submarine and ship fire extinguishing systems. It is a substitute product for water spray and haloalkane fire extinguishing systems. It is mainly used in the field of submarines and ships, and can also be used in other civilian merchant ship fire extinguishing nozzles. and other fields. (2) Background technology

[0002] The status of the fire extinguishing system is extremely important in the safety guarantee system of submarines and ships. In order to extinguish the fires in the living compartments of submarines and ships, a water sprinkler system is currently installed. Although the water sprinkler system can effectively extinguish solid fires, it cannot There are disadvantages such as a large amount of water for fire extinguishing, a single type of fire extinguishing, and unsatisfactory fire extinguishing efficiency for oil fires and cable fires, and it will caus...
