Abstract

The invention discloses a high-pressure thin water spray fire-fighting injector used in submarine and ship, comprising injector shell, injector patchplug, central air spout, spherical air spout, outer air spout, internal filtering net, metallic sealing bale and dust shield. The shape of injector shell is two conical surfaces, the top of conical surface neat top part is plain, the central part is equipped with air spout; conical surface near to top is distributed with several spherical sir spouts; outer circle of conical surface near to top is next to another conical surface, a plurality of outer air spouts are installed on said conical surface. The air spouts on different installation surface are intercrossed, the injector shell and central air spout, spherical air spout and outer air spout, and injector shell and injector patch plug are all connected with each other through screw. The sealing employs metallic pad. The air spout is connected with the cavity of injector shell; the cavity of injector patch plug is equipped with stainless steel filtering net; another end of injector patch plug is connected with fire-fighting system through screw, and the injector shell is provided with dust cover.

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...
