Description
Technical field
The utility model relates to a kind of fire-fighting material that sprays fire extinguisher, and relating in particular to clear water or dry powder is the fire extinguisher of extinguishing chemical.
Background technology
Fire extinguisher is the indispensable equipment of fire-fighting that a kind of people are very familiar to, and fills extinguishing chemical by it and can be divided into foam, carbon dioxide, dry powder, alkyl halide, soda acid and plain water fire extinguisher etc.And dry powder extinguisher wherein and plain water fire extinguisher are power and extinguishing chemical is ejected on the comburant with the Compressed Gas in the fire extinguisher cylindrical shell all, to reach the effect that stamps out a fire.
In the cylindrical shell of existing dry powder extinguisher or plain water fire extinguisher all is that lower space is used to load extinguishing chemicals such as dry powder or clear water, the cylindrical shell upper space is then filling compressed nitrogen or carbon dioxide, this Compressed Gas is as the operation power of fire extinguisher, when fire extinguishing extinguishing chemical extruded the fire extinguisher cylindrical shell and sprays to burning things which may cause a fire disaster and put out a fire; Therefore its fire extinguisher cylindrical shell filling tube that is extinguishing chemical is again the container that fills of Compressed Gas.
The fire extinguisher of this structure shows in use that some are significantly not enough: at first extinguishing chemical can and compressed air fill and all need unify to carry out, and the filling of its Compressed Gas must fill website in specialty and finish, and using on-the-spot or laying a little and all can't carry out; And the can again of extinguishing chemical can be carried out after must earlier the air pressure in the fire extinguisher cylindrical shell being reduced to normal pressure, even fire extinguisher is few once opening the extinguishing chemical ejection, also must require in accordance with regulations thoroughly carrying out can extinguishing chemical again and charging into Compressed Gas after the release, not only filling is inconvenient, can efficient is low, and often forms the waste of compressed gas source.Fill compression gases such as nitrogen in the fire extinguisher cylindrical shell or carbon dioxide in addition, deposit with the passing of time easily build-up of pressure loss, operating pressure is difficult to keep and guarantee, the gas-storing capacity in the pressure vessel is reduced, during use directly influence spurt effect; Long-term band is pressed and is deposited the explosion that also causes cylindrical shell easily, makes fire extinguisher scrap fully.Moreover the cylindrical shell of this fire extinguisher has higher requirement of withstand voltage, needs the professional to deposit a little to fire extinguisher often and detects, to guarantee its safety in utilization; And for a large amount of capacity fire extinguishers, as transportable fire extinguisher, the withstand voltage properties of its cylindrical shell and use are dangerous can be changed along with the increase of cylindrical shell capacity, must bring the increase of manufacturing cost and use and management cost.When the extinguishing chemical of fire extinguisher cylindrical shell was dry powder, fire-fighting powder caused easily again under the effect of top gases at high pressure and hardens, and has a strong impact on spurting and the effect of putting out a fire of dry powder.
The utility model content
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved in the utility model provides a kind of built-in pressure storage type fire extinguisher, and it is stable that it not only has the fire extinguisher operating pressure, puts out effective; And can carry out the can of extinguishing chemical, safety easy to use easily.
In order to solve the problems of the technologies described above, built-in pressure storage type fire extinguisher of the present utility model, comprise the fire extinguisher cylindrical shell, on this fire extinguisher cylindrical shell, jet valve body is housed, jet hose and siphon pipe are housed on this jet valve body, and also hinged on jet valve body have a unlatching pressure handle, and described siphon pipe is positioned at the tube chamber of fire extinguisher cylindrical shell, also be provided with the storage air bottle in the tube chamber of described fire extinguisher cylindrical shell, this storage air bottle is fixedly installed on the jet valve body; Valve rod is installed on jet valve body versatilely, and pricker is equipped with by connecting rod in the lower end of valve rod; Between pricker front end and storage air bottle bottleneck, be provided with the gas bomb diaphragm seal; The upper end of described valve rod is corresponding to opening pressure handle.
In technique scheme, owing to adopt extinguishing chemical filling cylindrical shell and Compressed Gas to fill the separate structure of bottle, both functions are independent separately; The fire extinguisher cylindrical shell only is used for extinguishing chemicals such as splendid attire dry powder or clear water, and the fire extinguisher cylindrical shell is in atmospheric pressure state when not using, and cylindrical shell does not bear gas pressure; The storage air bottle only fills working gas such as compressed carbon dioxide or nitrogen, thereby has avoided with the passing of time depositing the deficiency of the aero operating pressure reduction that brings, and has guaranteed the stable of fire extinguisher operating pressure; Not only can momentarily change the storage air bottle during use, and can carry out replenishing or can of extinguishing chemical whenever and wherever possible, make fire extinguisher can keep continuous duty, prolonged the stream time of single fire extinguisher greatly, the scene that has effectively the strengthened fire extinguisher effect of putting out a fire to save life and property.Also owing to adopt this minute body structure, the fire extinguisher cylindrical shell is atmospheric pressure state, the can of one side extinguishing chemical or the additional cylindrical shell release problem that all do not exist, even under the few situation of extinguishing chemical ejection, also can carry out extinguishing chemical at any time replenishes and installs additional, it is very convenient quick that the can of extinguishing chemical becomes, and can not form the waste of Compressed Gas; Cylindrical shell has not improved the safety in utilization of fire extinguisher again with pressure on the other hand, effectively reduces the manufacturing cost and the use and management cost of fire extinguisher cylindrical shell yet.Again owing to the storage air bottle is loaded in the fire extinguisher cylindrical shell regularly by jet valve body, the jet valve body that unclamps on the cylindrical shell just can be changed the storage air bottle apace and install extinguishing chemical additional, make the fire extinguisher operation of putting out a fire continuously, the storage air bottle adopts built-in structure, also be easy to carry and move, with rapid input fire-extinguishing location; The fire extinguisher of this structure also is more suitable for using on the means of transports such as foreign-going ship simultaneously.
