Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of dry powder extinguishing installation, the type self-destroyed dry powder extinguishing installation of particularly a kind of explosion.
Background technology
At present, normally used dry powder extinguisher can be divided into two types with regard to its dry powder spray function.The first kind is to be that housing, gases at high pressure are power with the box hat, is perforation with the nozzle, sprays the jet type dry powder fire extinguisher of dry powder with pattern; Second type is to be housing with paper, plastic body, and high-pressure gas is a power, with the explosion type dry powder extinguisher of the comprehensive spreading dry powder of outburst form.First kind jet type dry powder extinguisher structure is complicated heavy, and useful life is short, and will reprocess once one or two years.Second type with high-pressure gas as power, combustion gas itself just causes flare easily or lights other combustibles, uses this series products fire extinguishing, effect is bad.
Developed many explosion type dry powder extinguishers both at home and abroad, the humidity resistance that has is poor; The thin metal of the employing that has is the extinguishing device housing, makes the electrical equipment short circuit after the fragmentation easily, and the scope of use is little, and raw material needs import, manufacturing process complicacy, the cost height of product.
Therefore; Someone seeks other development route, has just solved above-mentioned problem like " a kind of portable dry powder extinguisher shell body " of one Chinese patent application 91226234.6, and it is made up of cylindrical shell, covers, trim ring, fixing collar etc.; Cylindrical shell adopts blank sheet of paper to stick with paste, up and down the two ends outward flanging.Covers is that the cylindrical shell flanging is inserted respectively in the cannelure of upper and lower cover with being connected of cylindrical shell, after pushing down with trim ring, tightens up with self-tapping screw again, apply at cylinder body outer wall and touch the next protection against the tide of film processing, and the employing gunpowder is a power.Though solved protection against the tide, do not solved the high problem of product cost, the also not basic dynamical problem that solves.Adopt gunpowder, the easy damp failure of blasting fuse; As power, effect is bad with high-pressure gas in employing.Moreover the part that this patent is used is more, assembles numerous and diverse.
