Description
[technical field]
The utility model relates to fire fighting device technical field, specifically a kind of ultra-fine impulse dry powder automatic fire extinguisher.
[background technology]
In life, we likely meet with fire at any time, fire extinguisher is one of common fireproofing installation, chemical substance is placed in fire extinguisher, in order to rescue fire extinguishing calamity, it leaves the place of public place or possibility breaking out of fire in, and in different types of fire extinguisher, the composition of filling is different, is aim at different fire alarms and establish.
Ultra-fine pulse fire-fighting technique is the most efficient current fire-fighting technique, because attack time is less than 1 second usually, and the sealing not requirement to application places, be therefore highly suitable for the object of protection of non-close space or outdoor.Unmanned and the indeterminable places of traditional means such as ultra-fine impulse dry powder automatic fire extinguisher can be applied in the power distribution cabinet of switchgear house, cable duct, cable interlayer, communication station, passive spontaneous startup can be realized, catching fire, the initial stage will or knock out, and realizes suppressing in early days, reduces the loss.
But common nozzle has once-through type nozzle and wide-angle type nozzle on ultra-fine impulse dry powder automatic fire extinguisher now on the market.Once-through type nozzle, refer to the nozzle with a columniform spray road, gas powder mixed flow at a high speed can a bit carry out a fire extinguishing by nozzle to certain fast, all dry powder is focused on certain a bit by it, being limited in scope of fire extinguishing, the speed of the gas powder stream that it ejects is determined by the pressure storing up powder tank.Wide-angle type nozzle only has a Ge Pen road, the port of export is the horn-like of profound type, this structure effectively can carry out a diffusion to dry-powder air-current, expand the area that nozzle can cover, but because gas powder obtains diffusion, its pressure ejected can decrease, so the coverage of class nozzle is shorter.Above-mentioned nozzle is all single spraying road, and the area coverage of single pass nozzle is little, and gas powder material directly directly sprays from carrier pipe in nozzle, and because the mixing of gas powder exists uneven possibility, the gas powder mixing ejected from nozzle is uneven, and extinguishing effect is not good.
[summary of the invention]
The purpose of this utility model sprays to overcome existing ultra-fine impulse dry powder automatic fire extinguisher single hole the technical barrier causing extinguishing effect not good, designs a kind of ultra-fine impulse dry powder automatic fire extinguisher that effectively can expand dry-chemical fire extinguishing scope, ensure the comprehensive covering of dry powder.
To achieve these goals, a kind of ultra-fine impulse dry powder automatic fire extinguisher is provided, comprise suspender, can, powder extinguishing agent, gas-forming agent, aluminium film, outer cover, nozzle, electricity initiator and temperature-sensitive starting element, described can top is provided with temperature-sensitive starting element, the side of can is provided with suspender, electric initiator is provided with in described can, gas generator and powder extinguishing agent, nozzle is provided with bottom can, nozzle place envelope has aluminium film, on nozzle, cover has outer cover, described outer cover is inner axially offers upright opening, multiple diffusion taper hole be communicated with upright opening is tangentially offered along annular inner wall in outer cover.
The top of described temperature-sensitive starting element is provided with temperature-sensing probe becket, and the base outer ring of described temperature-sensitive starting element is provided with hold-down screw, and centre circle is provided with startup binding post, and inner ring is provided with temperature-sensitive and starts feedback connection end.
Described suspender and can one-body molded, suspender has two fixing holes.
Described electric initiator wire, bridge silk, ignition powder block, ignition powder block is filled in gas-forming agent, and bridge silk connects one end of two wires, and is embedded in ignition powder block, and the other end of wire stretches out outside ignition powder block.
Described outer cover is fixed on nozzle by helicitic texture.
The utility model compared with the existing technology, its advantage is: nozzle overlaps in the outer cover that has and offer upright opening, multiple diffusion taper hole be communicated with upright opening is tangentially offered along annular inner wall in outer cover, expanded the coverage of extinguishing chemical after extinguishing chemical fully mixes in upright opening by diffusion taper hole, improve extinguishing effect; Top is provided with temperature-sensitive starting element, can start the instruction of backward alarm host machine feedback action by implement device temperature-sensitive; Side is provided with suspender, is fixed on ceiling or wall by screw and nut, applied widely, can put out rapidly A, B, C class and active electrical fire.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1
With reference to figure 1, the utility model comprises suspender, can, powder extinguishing agent, gas-forming agent, aluminium film, outer cover, nozzle, electric initiator and temperature-sensitive starting element, can top is provided with temperature-sensitive starting element, the side of can is provided with suspender, suspender and can one-body molded, suspender has two fixing holes, electric initiator, gas generator and powder extinguishing agent is provided with in can, nozzle is provided with bottom can, nozzle place envelope has aluminium film, and on nozzle, cover has outer cover.
