Abstract
The utility model relates to a gas storage type fire extinguisher, which is provided with a barrel, and a valve is mounted on the barrel, and is communicated with a spray pipe, a suction pipe and a gas storage bottle. The fire extinguisher is characterized in that: the spray pipe is provided with a switch, the valve is provided with a handle, one end of the switch is connected with a high-pressure pipe, the other end of the switch is connected with a nozzle, the switch comprises a valve body, an inner sleeve is mounted on the front end of the valve body, an outer sleeve is arranged outside the inner sleeve, and is screwed on the valve body, the inner sleeve is tightly compressed by the outer sleeve, a spool is arranged in the valve body, one end of the spool is hermetically matched with the inner sleeve, and the other end of the spool is connected with a pressing handle, which is connected with the valve body of the spray pipe through rivets. Since the control switch is added on the spray pipe and the angle between the suction pipe connector of a valve seat and a jet outlet is widened, the jet resistance is decreased, and thereby the fire-extinguishing performance of the fire extinguisher is optimized.
Description
Technical field
The utility model relates to a kind of fire extinguisher, relates in particular to a kind of cartridge operated extinguisher.
Background technology
Dry powder extinguisher and foam annihilator commonly used have air-stored and stored-pressure type.Cartridge operated extinguisher enjoys the market favor because of the safe of its storage.But the cartridge operated extinguisher of prior art exists a meeting to influence the problem of extinguishing property.Its structure such as Fig. 1 are made up of valve 11, cylindrical shell 12, jet pipe 13, gas cylinder 14 etc.The pressure-raising of depressing valve during operation is 15, and thimble 16 punctures the shrouding of gas cylinder 14, and the fire-retardant gas of high pressure in the gas cylinder 14 enters cylindrical shell 12.Because jet pipe 13 and cylindrical shell 12 are straight-through, so gas is carrying dry powder or foam is spouting from jet pipe.There is not switch control on the jet pipe 13, when in the cylindrical shell certain pressure being arranged, extinguishing chemical just begins ejection, but the jet length of fire extinguisher at this moment is far from reaching the designing requirement of product, when the pressure in the cylindrical shell reaches eject request by the time, some extinguishing chemical is injected has come out, thereby has cut down fire extinguishing effectiveness.
Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency, thereby develops a kind of cartridge operated extinguisher, to improve the extinguishing property of product.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of cartridge operated extinguisher, has cylindrical shell, valve is housed on the cylindrical shell, valve is connected with jet pipe, suction pipe, gas cylinder, it is characterized in that: have switch on the described jet pipe, described valve is provided with handle.
The technical solution of the utility model can also be further perfect:
As preferably, described switch one end and high-voltage tube join, and the other end links to each other with nozzle.
As preferably, described switch comprises valve body, the valve body front end is equipped with interior cover, there is overcoat interior cover outside, and described overcoat is threaded with valve body, and compresses interior cover by overcoat, in the described valve body spool is set, described spool one end and interior cover are sealed and matched, and the other end is connected with pressure handle, and described pressure handle is connected by rivet with the jet pipe valve body.
As preferably, described valve links to each other with jet pipe with suction pipe respectively with jet exit by the suction pipe interface; The angle of described suction pipe interface and jet exit axis is about 105 degree.
The beneficial effects of the utility model: owing on jet pipe, increased gauge tap, increased the angle of valve seat suction pipe interface and jet exit simultaneously, reduced to spray resistance, optimized the extinguishing property of fire extinguisher.
Description of drawings
Accompanying drawing 1 is the cartridge operated extinguisher structural representation of prior art;
Accompanying drawing 2 is a kind of structural representations of the present utility model;
Accompanying drawing 3 is jet pipe and construction of switch schematic diagrames of Fig. 2;
Accompanying drawing 4 is valve mechanism schematic diagrames of Fig. 2.
Description of reference numerals: suction pipe 1, cylindrical shell 2, jet pipe 3, nozzle 31, interior cover 32, overcoat 33, spool 34, valve body 35, rivet 36, spring 37, pressure handle 38, high-voltage tube 39, valve 4, valve body 41, handle 42, thimble 43, safeties 44, carrying handle 45, gas cylinder 5, base 6.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Cartridge operated extinguisher has cylindrical shell 2 as shown in Figure 2, and described cylindrical shell 2 is threaded with valve 4, described valve 4 is threaded with gas cylinder 5, described valve 4 and suction pipe 1 are threaded, and described valve 4 is threaded with jet pipe 3, and described cylindrical shell 2 embeds in the base 6.
Jet pipe 3 structures such as Fig. 3 have valve body 35, and described valve body 35 front ends have been installed interior cover 32, and described valve body 35 and overcoat 33 are threaded, cover 32 in compressing by overcoat 33, and described interior cover 32 and nozzle 31 are threaded.In the described jet pipe valve body 35 spool 34 is set, described spool 34 1 ends and interior cover 32 are sealed and matched, and the other end is connected with pressure handle 38.Described pressure handle 38 is connected by rivet 36 with jet pipe valve body 35, and described jet pipe valve body 35 1 ends are connected with high-voltage tube 39.
Valve mechanism such as Fig. 4 have valve body 41 handles 42, thimble 43, safeties 44, carrying handle 45 etc.
During operation, firmly break safeties 44, press handle 42 and thimble 43, thimble 42 stabs out gas cylinder 5, and the anti-flammability gas in the gas cylinder 5 enters cylindrical shell 2, is in sealing state between the valve body 35 of jet pipe 3 and the spool 34 at this moment, and gases can not leak in the cylindrical shell 2.Wait for 2-3 after second, when the pressure in the cylindrical shell rose to the required operating pressure of fire extinguisher, with subordinate pressure handle 38 of pressing on the jet pipe 5, spool 34 is pulled up the back to be separated with jet pipe valve body 35 sealing surfaces, and it is spouting that cylindrical shell 2 interior fire-retardant gases are carrying extinguishing chemical.Because pressure has reached operating pressure, the jet length of fire extinguisher meets the requirements fully.In addition, the valve seat suction pipe interface of prior art valve 11 and jet exit are about 90 degree, and the valve seat suction pipe interface of the utility model valve 4 and jet exit are about 105 degree, reduce to spray resistance, have optimized the extinguishing property of fire extinguisher.
