The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

As Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, this fire-extinguishing apparatus comprises: a casing 10, be provided with a water tank 11 with water in this casing 10, one bubble chamber 12 with foam connects a control valve 13 respectively, these control valve 13 other ends connect a pressurization group Pu 14, utilize these control valve 13 controls to help Pu 14 to this pressurization group Pu 14 or by the foam stream of this bubble chamber 12 through this control valve 13 to this pressurization through this control valve 13 by the current of this water tank 11, these pressurization group Pu 14 other ends are connected to the flexible pipe 15 of a pipeline, this flexible pipe 15 is connected to a spray gun 16 again, this spray gun 16 has an effluent switch 17, this spray gun 16 is placed on the bracing frame 18 in these casing 10 outsides, or other predeterminated position, respectively this bracing frame 18 is provided with an open-close on-off 19, and whether the startup at these open-close on-off 19 control pressurization group Pus 14.

The utility model is mainly installed a relief valve 20 on this pipeline of this

pressurization group Pu

14 and 16 of this spray guns, this relief valve 20 has an electric control gear 21, a water inlet 22, a delivery port 23, valve block 211 in these electric control gear 21 these relief valves 20 of control opens and closes, this water inlet 22 is connected with this pipeline, this delivery port 23 and this

water tank

11 or 12 arbitrary connections of this bubble chamber.

It more than is the general introduction of structure, position and the interconnected relationship of each assembly of the utility model; Then, again with each combination of components of the utility model and expect the effect statement as the back of reaching:

As Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, utilize above-mentioned assembly to form the utility model, when this fire-extinguishing apparatus uses, switch this control valve 13, desire uses the water (or the foam in this bubble chamber 12) in this water tank 11 to put out a fire, when taking out this spray gun 16, this open-close on-off 19 starts this pressurization group Pu 14 pressurizations, this electric control gear 21 cuts out this valve block 211 simultaneously, make water can't enter this relief valve 20 and directly to this flexible pipe 15, when pushing this effluent switch 17, water is promptly spouting by this spray gun 16, immediately fire fighting.

When fire fighting finishes, decontrol this effluent switch 17, this water is still in whole this fire-extinguishing apparatus, this spray gun 16 is put into this bracing frame 18, close this open-close on-off 19 simultaneously and stop this pressurization group Pu 14 pressurizations, this electric control gear 21 is opened this valve block 211 simultaneously, make water enter this relief valve 20 to this delivery port 23 and flow back to this water tank 11 (or this bubble chamber 12) by this water inlet 22, make in this flexible pipe 15 and do not have water, promptly do not have pressure, prolonged the service life of this flexible pipe 15, can not make this flexible pipe 15 have pressure yet, produce when being pressed onto accidentally and break, injure people or this fire-extinguishing apparatus.

The utility model is set up relief valve 20 in pipeline have outside the fire fighting function this fire-extinguishing apparatus, has more self-safe effect, can prevent that safety problem from producing, and increases the service life.

As Fig. 7, Fig. 8 and shown in Figure 9, the utility model can increase a water return pipeline 30 and a backwater change-over switch 31 in this pressurization group Pu 14 and this relief valve 20, in this casing 10, set up a backwater starting switch 32, these water return pipeline 30 1 ends connect back this water tank 11, this backwater change-over switch 31 is switched current through this relief valve 20, or the switching current return this water tank 11, this pressurization group Pu 14 actions of these backwater starting switch 32 startups.

When desiring to do test, whether confirm these control valve 13 positions earlier, only allow the water of this water tank 11 help Pu 14 through this pressurization in the tram.

Pull this backwater change-over switch 31 more upwards, touching this backwater starting switch 32 simultaneously allows this pressurization group Pu 14 move, make the water of this water tank 11 help Pu 14 to this water return pipeline 30 via this pressurization, because this backwater change-over switch 31 is switched upwards, water can't be sprayed via this flexible pipe 15 to this spray gun 16, but allow water get back to this water tank 11 by this water return pipeline 30.

Can do the test that whether can normally use to fire-extinguishing apparatus in addition, for making water form the test of a backflow, saving water resource, and can test in the original place, whether the extinguishing device placement space of need not worrying is enough, or problems such as other barrier or easy damp item are arranged.

The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
