Multi-nozzle fire extinguishing device

Abstract

The invention discloses a multi-nozzle fire extinguishing device, and belongs to the technical field of fire fighting equipment. The device comprises a bottle body, a shield, a valve seat, a rupture disk, a valve and a nozzle, the upper half part of the spray head is provided with an upper nozzle and four side nozzles, the upper nozzle is positioned right above the spray head, the side nozzles are uniformly distributed in the circumferential direction of the spray head, the front end surfaces of the upper nozzle and the side nozzles are spherical surfaces, and spray holes are distributed in the spherical surfaces; the lower half part of the spray head is of a cylindrical cavity structure, and a threaded section is machined on the outer circumferential surface of the cylindrical cavity structure; the valve seat is fixedly connected to a bottle opening of the bottle body, the spray head is connected with an internal thread on the valve in a matched mode through a threaded section of the lower half portion of the spray head, the spray head and the protective cover are fixed together through the upper nozzle and the side nozzle, after the protective cover and the bottle body are fixed, the rupture disk is pressed on the upper end face of the valve seat through the valve, and an opening of the bottle body is closed through the rupture disk. The liquid fire extinguishing agent can be gasified or the solid fire extinguishing agent can be quickly atomized and dispersed all around, so that the purposes of extinguishing fire and suppressing explosion are achieved.

Description

technical field [0001] The invention belongs to the technical field of fire fighting equipment, and in particular relates to a multi-spout fire extinguishing device. Background technique [0002] With the advancement of science and technology, people's awareness of fire safety has also increased. For fire suppression and explosion suppression in some special confined spaces, intelligent fire extinguishing systems will be used. The advantage of intelligent fire extinguishing systems is that they can be activated through monitoring and alarm systems without the presence of on-duty personnel. Fire extinguishing bottles are used to complete the fire extinguishing work, thereby reducing labor costs. [0003] When the fire extinguishing bottle is started, it releases the liquefied fire extinguishing agent through the nozzle on the fire extinguishing bottle. When the pressure of the liquefied fire extinguishing agent changes from the nozzle to the outside, it forms a spray and spre...

AI Technical Summary

Problems solved by technology

[0003] When the fire extinguisher is started, it releases the liquefied fire extinguishing agent through the nozzle on the fire extinguisher. When the pressure of the liquefied fire extinguisher changes from the nozzle to the outside, it forms a spray and spreads along the flow direction of the nozzle. Because the fire extinguisher usually It is fixed at a specific position, and the liquefied fire extinguishing agent ejected from the nozzle of the existing fire extinguisher bottle can only cover the fire field range of 0-90°. It is difficult for the nozzle of the fire extinguisher to effectively control the fire, which greatly reduces the effectiveness of the intelligent fire extinguishing system
