Abstract
The invention discloses an ultrahigh-pressure fire-fighting hose, belonging to the technical field of fire-fighting instruments, especially relating to a production technology of a fire-fighting hose. The hose has a structure of an inner layer, a middle layer and an outer layer, and a polyurethane rubber tube, a two-upper and one-lower twilled woven tube and a two-upper and two-lower twilled woven tube respectively serve as the inner layer, the middle layer and the outer layer. By adopting the three-layer structure, the pressure resistance of a product can be greatly enhanced, and the ultrahigh-pressure fire-fighting hose can bear a 6.0MPa ultrahigh-pressure fire-fighting water source, and is mainly applied onto high-pressure fire-fighting vehicles for extinguishing fire of an urban high-rise building and being capable of delivering water to the height of more than 300m. By adopting the two-upper and one-lower twilled woven tube and the two-upper and two-lower twilled woven tube as the middle layer and the outer layer respectively, besides the pressure resistance, the product has certain flexibility and wear resistance, thereby being beneficial to turning, folding and converting for use, and facilitating extension to different positions so as to improve the fire-fighting efficiency and reduce the labor intensity of operating staffs, and favorably prolong the service life of the product.
Description
Technical field
The invention belongs to the technical field of fire-fighting equipment, particularly the production technology of fire hose.
Background technique
At present, the highest design work pressure of fire-extinguisher water hose NBS is 2.5MPa, and fire-extinguisher water hose is that double-layer structure is formed, and internal layer is the polyurethane sebific duct, skin is woven tube, and woven tube is 1 time structure on woven 1, and in use its withstand voltage properties is poor, in addition high-pressure water, so, be not suitable for the fire extinguishing of tall building, be unfavorable for shortening flame extinction time, cause reduction to the loss of the person and property.
Summary of the invention
The present invention seeks to propose a kind of ultrahigh pressure fire-extinguisher water hose that is specially adapted to tall building.
Water band of the present invention is made up of three-decker, and internal layer is the polyurethane sebific duct, and the mesosphere is the twill weave pipe under 1 on 2, and skin is the twill weave pipe under 2 on 2.
The present invention adopts three-decker, has greatly improved the resistance to pressure of product, can bear the ultrahigh pressure fire water supply of 6.0MPa, is mainly used on the above high pressure fire fighting car of city high-rise fire extinguishing 300 meters height of water delivery.The present invention is because to adopt the mesosphere be that twill weave pipe, the skin under 1 is the twill weave pipe under 2 on 2 on 2, make product when having resistance to pressure, also have certain pliability and wear resistance, be beneficial to turning, knuckle conversion use, conveniently stretch into different parts, to improve the efficient of fire fighting, also reduce labor intensity of operating personnel, also be beneficial to the working life that prolongs product.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in Figure 1, internal layer of the present invention is polyurethane sebific duct 1, and the mesosphere is the woven twill weave pipe 2 of 1 undertissue's structure on 2, and skin is the woven twill weave pipe 3 of 2 undertissue's structures on 2.
Mesosphere and outer field woven tube 2,3 all adopt the polyester industrial yarn of high strong type, and internal layer adopts polyurethane adhesive tubing matter as lining, by the bonding method of elevated temperature heat, two-layer braid and polyurethane sebific duct is bonded together.
Claims (1)
1. ultrahigh pressure fire-extinguisher water hose is characterized in that described water band is made up of three-decker, and internal layer is the polyurethane sebific duct, and the mesosphere is the twill weave pipe under 1 on 2, and skin is the twill weave pipe under 2 on 2.
