Description
Technical field
The utility model relates to a kind of foam annihilator, is specifically related to a kind of stored-pressure type compressed gas bubble fire extinguisher.
Background technology
Foam annihilator is the widely used a kind of fire distinguisher of modern fire-fighting, mainly contains portable and cart type etc., by national standardThere are some specifications and model. It is suction type foam annihilator that existing fire extinguisher product is air suction type, adopts venturi to spray foamingPrinciple, fire extinguisher often cannot, under equal air pressure, increase gas-liquid flow range, and therefore, coefficient of foaming is inhomogeneous, and foam is residentTime is short, can not send dry foam, and covering and extinguishing ability are poor. For this reason, someone has proposed a kind of suction type foam annihilator,This fire extinguisher mainly by bottle, spurt head, nozzle and the telescopic frothing head of three joints forms, rely on the three telescopic frothing heads of joint andThe perforate of sidewall foam doubly in can sending, but adopt due to this kind of fire extinguisher or venturi foam theory, promote gasPressure reduce gradually along with the prolongation of injecting time, pressure is more and more lower, the air of suction is also fewer and feweri, coefficient of foamingMore and more less; Only better at injection initial stage foam performance, in the time of the later stage, can not form foam, therefore adopt this suction type bubbleThe foam stability of foam fire extinguisher is not strong, in addition, adopts this foam annihilator can not send dry foam.
In order to overcome the not strong defect of foam stability of this suction type foam annihilator, someone has proposed a kind of novel negative pressureFormula foam annihilator, this fire extinguisher is made up of housing, foam solution outlet and foam screen, and foam screen is also to adopt multistage foaming,This foam annihilator gas release is large, and good stability is a kind of foam device of high multiple, but this foam annihilator jet lengthFrom close to, affected its result of use.
Utility model content
Large and can not send the problem of dry foam on the impact of foaming properties in order to solve pressure oscillation in prior art. This practicality is newType provides a kind of stored-pressure type compressed gas bubble fire extinguisher, and this stored-pressure type compressed gas bubble fire extinguisher adopts positive-pressure type Compressed GasInitiatively air feed and do not need air amount mode, can constantly send stable foam.
A kind of stored-pressure type compressed gas bubble fire extinguisher, comprises pressure vessel, peace for storing gases at high pressure and foam mixing liquidBe contained in the foam maker in pressure vessel and be connected to the foam pipeline on foam maker. Described pressure vessel is provided with energyEnough connect the tube connector of air pump, on tube connector, be provided with transfer valve. On pressure vessel, be also provided with Pressure gauge. Described foam occursDevice comprises air admission hole, inlet and flow spoiler, and inlet is connected with feed tube, and the lower end of feed tube is stretched in foam mixing liquid.Foam maker is connected with foam pipeline, and the end of foam pipeline is connected with the foam gun for spraying foam.
Preferably, described foam gun is straight tube-like or is bell mouth shape.
Preferably, foam ejection valve is installed on foam pipeline.
Preferably, pressure vessel is vertical storage tank or horizontal tank.
Preferably, the bottom of pressure vessel is provided with blow-off pipe, is provided with blowoff valve on blow-off pipe.
Preferably, between foam maker and foam pipeline, be connected by flange.
The utility model compared with prior art, has following beneficial effect:
First, above-mentioned a kind of stored-pressure type compressed gas bubble fire extinguisher is without from extraneous air amount, just can produce even, exquisiteness,Stable kinetic energy foam, blow-off velocity is fast, wide coverage, jet length is far away. Secondly, foam maker and feed tube are fixedConnect, form integrative-structure, easy for installation. Then, in foam gun, do not need to arrange air entry, can be straight tube-like or be loudspeakerMouthful shape, makes simple, easy to operate. Finally, compared with conventional foam annihilator filling weight 80%, stored-pressure type compressed gasThe filling weight of body foam annihilator only needs 50%, can reach the ability of putting out same area fire, and have foam coverage and everyFrom effect.

Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, the utility model is elaborated.
A kind of stored-pressure type compressed gas bubble fire extinguisher, comprise pressure vessel 4 for storing gases at high pressure and foam mixing liquid,Be arranged on the foam maker 5 in pressure vessel 4 and be connected to the foam pipeline 3 on foam maker 5. Described pressure storageTank 4 is provided with the tube connector that can connect air pump, is provided with transfer valve 8 on tube connector. On pressure vessel 4, be also provided with pressureTable 7. Described foam maker 5 comprises air admission hole, inlet and flow spoiler, and inlet is connected with feed tube, under feed tubeEnd stretches in foam mixing liquid. Foam maker 5 is connected with foam pipeline 3, and the end of foam pipeline 3 is connected with useIn the foam gun 2 of ejection foam. Further, described foam gun 2 is straight tube-like or is bell mouth shape.
Further, foam ejection valve 9 is installed on foam pipeline 3.
Further, pressure vessel 4 is vertical storage tank or horizontal tank.
Further, the bottom of pressure vessel 4 is provided with blow-off pipe, is provided with blowoff valve 1 on blow-off pipe.
Further, between foam maker 5 and foam pipeline 3, be connected by flange 6.
Above-mentioned a kind of stored-pressure type compressed gas bubble fire extinguisher, when installation, need to make foam maker 5 and feed tube in advanceBecome a global facility and be placed in pressure vessel 4, making the air admission hole of foam maker 5 be positioned at the gas-phase space of pressure vessel 4In, the lower end of feed tube is stretched in the foam mixing liquid of bottom. When filled and process liquid and Compressed Gas, first open transfer valve8, the foam mixing liquid preparing is added in pressure vessel 4 by tube connector, then foam maker 5 is fixed on to pressure vesselIn 4; Again then, by tube connector to the interior using charged air pressure of pressure vessel 4, when pressure reaches 1.2MPa or other suitable pressureWhen power, close transfer valve 8. When breaking out of fire, first stored-pressure type compressed gas bubble fire extinguisher is pushed near the scene of a fire, rapidlyOpen foam ejection valve 9, foam mixing liquid enters in foam maker 5 by feed tube, simultaneously the interior gas phase of pressure vessel 4The Compressed Gas in space enters into foam maker 5 by air admission hole, and Compressed Gas and foam mixing liquid blending disturbance formTurbulent flow, the gas-liquid thing of turbulent condition impacts flow spoiler, the further compressed gas of vaporific drop of formation constantly shears, collides,Disperse to form foam. Foam enters foam pipeline 3 and continues mixed flow from foam ejection valve 9, arrives foam gun 2 and goes outMouth place is ejection foam directly, implements fire extinguishing or covering.
