Abstract
The utility model belongs to the fire-extinguishing appliance of extinguishing a fire. A portable fire extinguishing rod containing difluoro-monochloro-monobromo methane called as a 1211 fire extinguishing rod is composed of a nozzle, a hand wheel, a guard ring, a valve gate, a cylinder body, a piston, an inflation one-way valve, etc. The portable fire extinguishing rod containing difluoro-monochloro-monobromo methane utilizes stored-pressure nitrogen gas as power, drives fire extinguishing agent through the piston, sprays the fire extinguishing agent to a limited distance, and carry out fire extinguishing. The utility model has the advantages of simple structure, flexible operation, convenient portability and high efficiency and has the active action to extinguish the subminiature primary fire.
Description
The utility model belongs to the fire extinguishing appliance of the usefulness that fights a fire.
Two fluoro-chloro-bromo-methane Fire extinguishing clubs are hand fire extinguishers of a kind of low capacity, the extinguishing medium that fills in this fire extinguisher is a difluorochlobromo-methane, so this fire extinguisher is called the difluorochlobromo-methane fire extinguisher, because difluorochlobromo-methane abbreviates 1211 again as, its molecular formula is: F
2ClBrC, therefore this fire extinguisher is called 1211 fire extinguishers again.
In the low capacity portable fire extinguishers 1211 before the utility model is made, mainly be in same fire extinguisher cavity, to store extinguishing chemical and pressure nitrogen gas, during use, opening device head valve door, liquid 1211 extinguishing chemicals are ejected by nozzle through valve by suction pipe, put out a fire.This fire extinguisher requires the suction inlet of suction pipe to keep state down when operation, because the bigger injection angle of depression and the elevation angle all can make extinguishing chemical quite partly be left in the container, and causes fire extinguisher can not bring into play due extinguishing ability, has reduced fire-fighting efficiency.
Weak points such as the purpose of this utility model is exactly at above-mentioned portable fire extinguishers 1211, and spraying has the orientation restriction, and the extinguishing chemical utilization rate is low, and carried out substantial improvement.
The utility model utilizes piston that 1211 extinguishing chemicals and driving pressure nitrogen are separated into two partly, as long as one starts valve in making bar-shaped fire extinguisher cylindrical shell, pressurising nitrogen promptly promotes piston with 1211 extinguishing chemicals, from nozzle, spray, put out a fire, and can spray by arbitrary orientation.
By to Derwent world patent, Japan's special permission communique, the patent retrieval of the main country such as American and Britain, West Germany and Austria all finds no the situation that is analogous to the technical solution of the utility model.
The utility model, simple in structure, its nozzle, handwheel, relieving ring, valve, piston, the inflation check valve, the structural relation between each part such as cylindrical shell, well arranged, easy to assembly.
The utility model is by nozzle 1, handwheel 2, and relieving ring 3, valve 4, cylindrical shell 5, piston 6, inflation check valve 7 grades partly form. Be illustrated as the structure schematic diagram of this Fire extinguishing club. Its operation principle is such: pull relieving ring, rotate the handwheel open valve, the pressurising nitrogen pushing piston on cylindrical shell the right sprays 1211 extinguishing chemicals from nozzle, put out a fire.
Liquid state 1211 extinguishing chemicals in the utility model and the separation structure of reservoir pressure nitrogen are the isobaric memory structures of a kind of separation.Can be during inflation by being fixedly mounted on the check valve inflation in the Fire extinguishing club.So compact conformation is convenient light and handy, can use repeatedly.
The utility model, the inventor has following characteristics through overtesting:
1. extinguishing chemical utilization rate height has guaranteed extinguishing ability;
2. simple and reliable for structure, easy to operate, can realize comprehensive injection;
3. volume is little, and is easy to carry, wide application;
4. manufacturing process is simple, and is economical and practical, the suitable production in enormous quantities in enormous quantities.
The utility model is portable 1211 fire extinguishers of a kind of novel bar-shaped stored-pressure type, to having positive effect from the beginning of putting out a fire to save life and property of small-sized fire.
Claims (1)
- A kind of stored-pressure type difluorochlobromo-methane of partly forming by nozzle, handwheel, relieving ring, valve, cylindrical shell, piston and inflation check valve etc. (promptly 1211) Fire extinguishing club, the one package structual that it is characterized in that liquid 1211 extinguishing chemicals and reservoir pressure nitrogen, for separating isobaric memory structure, aerating device is the check valve inflatable structure that is fixedly mounted in the Fire extinguishing club.
