Embodiment 1

[0034] Such as figure 1 , figure 2 As shown, a high-pressure water mist fire extinguishing nozzle 10 (abbreviation: nozzle) of the present invention is mainly composed of a nozzle housing 1, a nozzle adapter 2, a nozzle 3, an internal filter 4, a metal sealing gasket 5 and a dust cover 6. . The profile of the nozzle housing 1 is two conical surfaces 101, 102, the top surface 103 of the conical surface 101 is a plane, and a nozzle 3 is installed at the center of the top surface 103, and the normal line of the conical surface 101 is clamped with the axis of the nozzle 10. The angle is 25 degrees; 3 nozzles 3 are evenly distributed on the conical surface 101, and these nozzles 3 choose a spiral groove structure, such as Figure 8 As shown, the swirl plate structure can also be selected, such as Figure 10 Shown; The spray angle of nozzle 3 is selected as 30 degrees, and the normal line of the outer ring conical surface 102 near the top surface conical surface 101 and the axis...

Embodiment 2

[0039] A second embodiment of a high-pressure water mist fire extinguishing nozzle 10 of the present invention is as follows image 3 , Figure 4 As shown, compared with the first embodiment, the difference is that the nozzle housing 1 of the second embodiment is designed as a conical surface 101, the top surface 103 of the conical surface 101 is a plane, and the center of the top surface 103 is installed There is one nozzle 3, and the angle between the normal line of the conical surface 101 and the axis of the nozzle 10 is 39 degrees; 6 nozzles 3 (or multiple nozzles) are evenly distributed on the conical surface 101; other shapes and structures And requirements are all the same as the foregoing embodiment one.

Embodiment 3

[0041] Embodiment three of the present invention is as image 3 , Figure 4 As shown, compared with Embodiment 1, the difference is that the nozzle housing 1 of Embodiment 3 is designed as a conical surface 101, the top surface 103 of the conical surface 101 is a plane, and the center of the top surface 103 is installed There are 3 nozzles 3; the angle between the normal of the conical surface 101 and the axis of the nozzle 10 is 39 degrees; 6 nozzles 3 (or multiple nozzles) are evenly distributed on the conical surface 101; other shapes and structures And requirements are all the same as the foregoing embodiment one.

Abstract

The high-pressure water mist fire extinguishing nozzle consists of a nozzle housing, a nozzle adapter, a nozzle, an internal filter, a metal sealing gasket and a dust cover. The shape of the nozzle housing is two conical surfaces, the top surface of the conical surface near the top is a plane, a nozzle is installed in the center of the top surface, and a plurality of nozzles are evenly distributed on the conical surface near the top surface; There is another conical surface adjacent to the outer ring of the conical surface near the top surface, and multiple nozzles are evenly distributed on this conical surface, and the nozzles on different installation surfaces are arranged alternately; the nozzle shell and the nozzle, the nozzle shell and the nozzle The adapters are all threaded, and the end surface is sealed with a metal gasket; the nozzle is connected to the inner cavity of the nozzle housing; the inner cavity of the nozzle adapter is equipped with a stainless steel filter; the other end of the nozzle adapter is threaded It is connected with the pipeline of the fire extinguishing system; a dust cover is installed above the nozzle housing. It has the advantages of rapid fire extinguishing, low water consumption, seawater corrosion resistance, and has the value of popularization and application.

Description

(1) Technical field [0001] The invention relates to a high-pressure fine water mist fire extinguishing nozzle used in naval submarine and ship fire extinguishing systems. It is a substitute product for water spray and halogenated alkane fire extinguishing systems. It is mainly used in the field of submarines and ships, and can also be applied to other civilian merchant ships. Fire protection and other fields belong to equipment for fire protection systems. (2) Background technology [0002] The fire extinguishing system plays an extremely important role in the safety guarantee system of submarines and ships. The development of modern submarine and ship technology has put forward higher requirements for fire prevention and control in important areas such as power engine rooms, sleeping rooms, and weapon rooms on board. In order to extinguish fires in submarines and ships, the original fixed fire extinguishing system is Halon 1301 fire extinguishing system and water sprinkler ...
