Disposable fire extinguisher based on national standard carbonate beverage bottle

Abstract

The invention discloses a disposable fire extinguisher based on a national standard carbonate beverage bottle. A carbonate beverage bottle is hung in a shell in a suspended manner and is in a vertical shape with a downward opening; a fire extinguisher valve is arranged at a bottle opening of the carbonate beverage bottle in a sleeving manner; the fire extinguisher valve comprises a valve main body of which the cross section is U-shaped; internal screw threads which are matched with external screw threads in the bottle opening of the carbonate beverage bottle are formed in the inner wall of the valve main body; a spraying nozzle which is communicated with the inner cavity of the valve main body is arranged on the valve main body; an automatic pressure relief safety valve is arranged on the carbonate beverage bottle; a 'scrap' identifier and a 'switch' identifier are arranged at the upper part of the carbonate beverage bottle; a fastening ring which is used for sheltering the 'scrap' identifier is annularly arranged on the carbonate beverage bottle in a sleeving manner; a pressure gauge which is used for detecting the pressure of the carbonate beverage bottle is mounted on the fastening ring; a supporting bulge is arranged corresponding to the fastening ring in the shell. According to the disposable fire extinguisher based on the national standard carbonate beverage bottle, a conventional fire extinguisher steel cylinder is replaced by selecting the carbonate beverage bottle; a fire extinguishing liquid is pushed to extinguish fire through CO2; the cost is greatly reduced; the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fire extinguishers, in particular to a disposable fire extinguisher based on a national standard carbonated beverage bottle. Background technique [0002] To achieve the speed of producing one ordinary fire extinguisher per second, it needs a fire extinguisher factory with 1,000 employees, but 10 employees can solve the problem of producing carbonated drinks at this speed. The cylinder of the fire extinguisher accounts for the largest cost of the fire extinguisher, because the factory building is large, the equipment is expensive, and the land occupation is also large. After the most automated, the employment is indispensable, and the certification inspection fee is also expensive; Hearing negative news reports about fire extinguishers, such as: overdose will kill you, fire extinguishers that lack maintenance are like time bombs, the pressure is normal but can’t be fired, unscrupulous repairers, etc. Ord...

AI Technical Summary

Problems solved by technology

[0006] The national standards of various countries have standards for disposable carbonated beverage bottles, but the content of the standard does not require that water pressure inspection must be done every time; because the water pressure inspection is to fill the water to the full before pressurizing, if there is a storm, it will not Hurt people, because the liquid will not shrink in volume after pressurization; with the same principle, the liquid level of the liquid has been added to the bottleneck when it is erected. Deformation; when deformed, the pressure drops immediately, and the shape after deformation is easy to distinguish, but as soon as the diameter becomes larger, the safety valve releases the pressure immediately (only when the national standard of the country of use is mandatory), because blasting will not hurt people; use The period is long, and the national standard disposable fire extinguishers cannot be recharged after use; therefore, it is not necessary to do a water pressure test every few years with disposable carbonated beverage bottles, because there has never been an incident of plastic carbonated beverage bottles bursting and hurting people
