Description
Technical field
This utility model relates to a kind of gas fire-fighting fire-extinguishing equipment, particularly relates to a kind of fire extinguisher of heptafluoropropane, belongs to
Extinguisher technical field.
Background technology
Gas fire-fighting fire-extinguishing equipment fire extinguisher of heptafluoropropane mostly is interior pressure storage type in the market, and it is by seven fluorine
Propane extinguishing chemical is collectively stored in a gas bomb with driving gas nitrogen, and sets up certain pressure store, at gas bomb
After bottle valve is opened, due to the pressure reduction inside and outside gas bomb, the nitrogen in gas bomb drives heptafluoro-propane extinguishing chemical to be transported to needs
The protection zone of fire extinguishing.In this fire extinguishing system, heptafluoro-propane and nitrogen storage in same steel cylinder, nitrogen meeting under a certain pressure
Being dissolved in heptafluoro-propane extinguishing chemical, along with the reduction of pressure in course of conveying, nitrogen can separate out, and forms bubble and gas-liquid two-phase
Stream, reduces fluid ability and the extinguishing effect of extinguishing chemical；Simultaneously because pressure source pressure is in attenuation state all the time so that fire extinguishing
Agent fed distance is limited, it is impossible to meet the requirement of long-distance sand transport.
For above-mentioned technological deficiency, market occurs again a kind of outer pressure storage type fire extinguisher of heptafluoropropane, gas will be driven
Body nitrogen separates disposal with heptafluoro-propane extinguishing chemical, still uses nitrogen to drive the form of extinguishing chemical to be achieved.As China is special
Technical scheme in profit (ZL201420276342.1).It is easy under the impact of high pressure nitrogen to there is decompressor in such device
The shortcoming damaged；Further, its fire extinguishing system initial stage pressure can not reach design load at once, but is gradually incremented to by 0
Design load.
Summary of the invention
The technical problems to be solved in the utility model is, the shortcoming overcoming prior art, propose one have storage pressure function,
The outer pressure storage type fire extinguisher of heptafluoropropane of protecting against shock function.
This utility model is that the technical scheme solving the proposition of above-mentioned technical problem is: 1. a fire extinguisher of heptafluoropropane,
Including: gas bomb and driving bottle；It is characterized in that；Storage heptafluoro-propane medicament in described gas bomb, it on equipped with container value with
Air relief valve, storage nitrogen in described driving bottle, equipped with starting valve on it；Described startup valve is with described air relief valve by pipeline even
Connect；Described air relief valve includes valve body and spool；Have on described valve body the air inlet being connected with described pipeline and with described gas storage
The gas outlet that bottle connects；Described spool is positioned at described valve inner, and by described air inlet with go out under the pressure of a spring
QI KOU is isolated；Described air inlet is built with restricting orifice.
Such scheme is further improved by: is also equipped with low height of letting out on described air relief valve and seals valve；The valve of described air relief valve
Also have on body one spigot joint with what described container value was connected；The gas outlet of described spigot joint and described air relief valve connects, both it
Between diaphragm is installed.
Such scheme is further improved by: equipped with the liquid level emasuring device containing warning function on described gas bomb.
Such scheme is further improved by: equipped with Pressure gauge on described gas bomb.
The fire extinguisher of heptafluoropropane that this utility model provides, extinguishing chemical and driving nitrogen are separately stored in different vessels
In, increase air relief valve between two containers, and at the air inlet increase restricting orifice of air relief valve, prevent high pressure nitrogen impact decompression
Valve, extends the air relief valve life-span, increases air relief valve reliability.Meanwhile, air relief valve increases diaphragm, so can be by initial pressure
Sealing, when pressure reaches design load, rupture of diaphragm, system is opened, hereby, it is achieved that reach when system is opened to set pressure
Export.The fire extinguisher of heptafluoropropane that this utility model provides, is the side spurted of a kind of constant pressure in actual applications
Formula is achieved, and while using less storage bottle, extinguishing device can be allowed to have farther conveying capacity, spurt speed faster, go out
Fire effect is more preferable.

Detailed description of the invention
Embodiment
The fire extinguisher of heptafluoropropane of the present embodiment is as it is shown in figure 1, include: gas bomb 2 and driving bottle 1；Gas bomb 2 internal memory
Storage heptafluoro-propane medicament, equipped with liquidometer 6, container value 5 and air relief valve 3 on it, drives storage nitrogen in bottle 1, equipped with opening on it
Dynamic valve；Start valve to be connected by pipeline with air relief valve 3.
As shown in Figures 2 and 3, air relief valve 3 includes valve body 12 and spool 14；There is on valve body 12 air inlet being connected with pipeline
Mouth 7 and the gas outlet 10 being connected with gas bomb 2；It is internal that spool 14 is positioned at valve body 12, and by air inlet under the pressure of spring 13
Isolation is closed with gas outlet；Air inlet 7 is built with restricting orifice 8.
It is also equipped with low height of letting out on gas bomb 5 and seals valve 4；Also there is on the valve body 12 of air relief valve 3 one and let out high envelope valve 4 even with low
Spigot joint 11 connect；Spigot joint 11 connect with the gas outlet 10 of air relief valve 3, are provided with diaphragm 9 between the two.
The air relief valve 3 of the extinguishing device of the present embodiment is in such as Fig. 3 state, and system is in closed state.Start valve to close,
Container value 5 is closed, and low high envelope valve 4 of letting out is in low pressure release conditions.
Opening along with starting valve, high pressure nitrogen, by driving bottle 1 to discharge, enters air relief valve 3 through piping, preferentially by throttle orifice
Plate 8 carries out reducing pressure for the first time, prevents high pressure nitrogen from impacting air relief valve 3, and then nitrogen promotes spool 14 compression spring 13 so that subtract
Pressure valve 3 is in opens such as Fig. 2 state, and nitrogen arrives gas outlet 10, and now, low high envelope valve 4 of letting out is in opening, therefore,
Start the insufficient pressure of container value 5；Further, nitrogen also can enter among spigot joint 11, there is diaphragm 9 in spigot joint 11,
So pressure can not let out high envelope valve 4 by spigot joint 11 releases to the lowest immediately, when accumulation of pressure to a certain extent, exceed diaphragm 9 and hold
During stress, diaphragm 9 ruptures, and nitrogen could enter spigot joint 11, and then enters low high envelope valve 4 of letting out, and low high envelope valve 4 of letting out cuts out, so,
The nitrogen pressure entering gas bomb 2 just be enough to open container value 5, thus container value 5 discharges, and starts spraying medicine and puts out a fire.
Patrol and examine monitoring for convenience, equipped with Pressure gauge on gas bomb 2.
This utility model is not limited to the various embodiments described above, the technical scheme that all employing equivalents are formed, and all falls within this
The protection domain that utility model requires.
