Embodiment 1

[0035] Such as figure 2 , image 3 As shown, the present invention is a high-pressure water mist fire extinguishing nozzle for submarine and ship living cabins, mainly consisting of a nozzle housing 1, a nozzle adapter 2, a central nozzle 3, surrounding nozzles 4, outermost nozzles 5, and an internal filter 6 , Copper sealing washer 7 and dust cover 8 are formed. The profile of this nozzle housing 1 is two conical surfaces (121,122), and the top surface 123 of conical surface 121 is a plane, and a nozzle 3 is installed in the center of top surface 123, and the normal line of conical surface 121 and shower nozzle 12 The angle between the axes is β 1 , three nozzles 4 are evenly distributed on the conical surface 121; the angle between the normal of the outer conical surface 122 and the axis of the nozzle 12 is β 2 , β 2 >β 1 . Six nozzles 5 are evenly distributed on the conical surface 122, and the nozzles 4 and 5 are arranged alternately. The nozzle housing 1 is screwe...

Embodiment 2

[0039] see Figure 4 , Figure 5 , a kind of high-pressure fine water mist fire extinguishing nozzle of submarine and ship living cabin of the present invention, by nozzle housing 1, nozzle adapter 2, center nozzle 3, surrounding nozzle 4, internal filter screen 6, red copper sealing washer 7 and dustproof cover 8 composition. The shape of the nozzle housing 1 is a conical surface 121, the top surface 123 of the conical surface 121 is a plane, and a nozzle 3 is installed at the center of the top surface 123, and the angle between the normal line of the conical surface 121 and the axis of the nozzle 12 is β 1 , six nozzles 4 are evenly distributed on the conical surface 121; nozzle housing 1, nozzle 3 and nozzle 4 are screwed together; nozzle 3, nozzle 4 and nozzle housing 1 are sealed with copper gaskets on the end face form. The nozzle housing 1 and the nozzle adapter 2 are connected through threads, and the sealing form of the end surface with a copper gasket is adopted. ...

Embodiment 3

[0042] see Image 6 , Figure 7 , a kind of high-pressure fine water mist fire extinguishing nozzle of submarine and ship living cabin of the present invention, by nozzle housing 1, nozzle adapter 2, center nozzle 3, surrounding nozzle 4, internal filter screen 6, red copper sealing washer 7 and dustproof cover 8 composition. The profile of the nozzle housing 1 is a conical surface 121, the top surface 123 of the conical surface 121 is a plane, and three nozzles 3 are installed at the center of the top surface 123, and the angle between the normal line of the conical surface 121 and the axis of the nozzle 12 is β 1 6 nozzles 4 are evenly distributed on the conical surface 121, and the nozzles 3 and 4 are arranged alternately. The nozzle housing 1 is screwed with the nozzle 3 and the nozzle 4 through threads, and the structure of the nozzle 3 and the nozzle 4 is the same, such as Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the flow rate and spray angle of no...

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...
