Abstract
The utility model discloses a high-pressure fire hose, which comprises a weaving layer and a lining layer. The weaving layer is a twilled weaving tube woven by polyester filament yarn in a two-up and two-down mode; the lining layer located inside the weaving layer is a vulcanized polyurethane pipe, and the thickness of the lining layer is 1 to 3mm; and the diameter of the high-pressure fire hose is 20 to 40mm. As the outer layer of the high-pressure fire hose is woven by polyester filament yarn and the lining layer adopts vulcanized polyurethane material, wear-resisting performances are enhanced, and the service life of the fire hose is prolonged. The high-pressure fire hose has working pressure of 8MPa and blasting pressure of 16MPa.
Description
Technical field
The utility model relates to a kind of fire fighting device, is specifically related to a kind of high pressure fire fighting water band.
Background technique
Fire-extinguisher water hose has another name called water hose, is a kind of tubulose narrow fabrics that can bear certain liq pressure, according to withstand voltage large I, is divided into plain edition and high pressure type fire-extinguisher water hose.The working pressure of fire-extinguisher water hose is generally 2.5MPa at present, and traditional fire-extinguisher water hose be take rubber as liner, and outer surface is wrapped in flax braided fabric, and the withstand voltage properties of this fire-extinguisher water hose is poor, can not be suitable for high-pressure water, cannot be applicable to tall building or forest-fire prevention; And because fire-extinguisher water hose can drag at ground lay conventionally, making this fire-extinguisher water hose easy to wear, working life is short.
Model utility content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high pressure fire fighting water band, can bear high hydraulic pressure, wear-resisting, long service life.
For addressing the above problem, the technological scheme that the utility model adopts is as follows:
A high pressure fire fighting water band, it comprises braid and inside liner, described braid is the twill weave pipe with 2 times establishments on polyester filament 2; Described inside liner is positioned at braid inside, and it is sulfuration polyurethane tube, and the thickness of inside liner is 1-3mm; The diameter of described high pressure fire fighting water band is 20-40mm.
The utility model can also be realized by following scheme:
As a kind of preferred scheme of the present utility model, the outer surface of described sulfuration braid is coated with one deck wearing layer, and described wearing layer is polyether-ether-ketone resin coating or polyurea elastomer coating.
As a kind of preferred scheme of the present utility model, the inwall of described inside liner is coated with the polyurethane water-proof layer that 0.3-0.5mm is thick.
Compared to existing technology; the beneficial effects of the utility model are: high pressure fire fighting hose jacket described in the utility model adopts polyester filament to work out; inside liner adopts sulfuration polyurethane material, has strengthened its wear-resisting property, thereby has extended the working life of fire-extinguisher water hose; High pressure fire fighting water band working pressure described in the utility model is 8MPa, and bursting pressure is 16MPa.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is preferred embodiment structural representation of the utility model.
Embodiment
As shown in Figure 1, high pressure fire fighting water band described in the utility model, it comprises braid 1 and inside liner 2, described braid 1 is the twill weave pipe with 2 times establishments on polyester filament 2; Described inside liner 2 is positioned at braid 1 inside, and it is sulfuration polyurethane tube, and the thickness of inside liner 2 is 1-3mm; The diameter of described high pressure fire fighting water band is 20-40mm.
The utility model can also be realized by following scheme:
As a kind of preferred scheme of the present utility model, the outer surface of described sulfuration braid is coated with one deck wearing layer 3, and described wearing layer 3 is polyether-ether-ketone resin coating or polyurea elastomer coating.Polyether-ether-ketone resin and SPUA have heat-resisting, corrosion-resistant, wear-resistant, can further strengthen the wear-resisting property of fire-extinguisher water hose.
As a kind of preferred scheme of the present utility model, the inwall of described inside liner 2 is coated with the polyurethane water-proof layer 4 that 0.3-0.5mm is thick.
Above-mentioned mode of execution is only preferred implementation of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
