Abstract
The invention provides an ultrahigh pressure fire-fighting hose, belongs to the technical field of fire-fighting equipment and particularly relates to a production technology of a fire-fighting hose. The fire-fighting hose consists of three layers, wherein an inner layer is a polyurethane rubber hose, a middle layer comprises two upper twilled braided hoses and a lower twilled braided hose, and an outer layer comprises two upper twilled braided hoses and two lower twilled braided hoses. The ultrahigh pressure fire-fighting hose adopts a three-layer structure, can bear a 6.0MPa ultrahigh pressure fire-fighting water source and is mainly applied to a high pressure fire fighting truck with more than 300-meter height and used for urban high-rise fire fighting and water delivery, and the pressure resistance of the hose is greatly improved. Due to the fact that the middle layer comprises the two upper twilled braided hoses and the lower twilled braided hose, and the outer layer comprises the two upper twilled braided hoses and the two lower twilled braided hoses, the ultrahigh pressure fire-fighting hose has pressure resistance and certain flexibility and abrasive resistance, turning and folding transformation in use is facilitated, the hose can conveniently extend into different positions to improve the fire fighting efficiency, the labor intensity of operators is also reduced, and the prolonging of the service life of the hose is further facilitated.
Description
Technical field
The invention belongs to the technical field of fire-fighting equipment, particularly the production technology of fire hose.
Background technology
At present, the highest design work pressure of fire hose national standard is 2.5MPa, and fire hose is that double-layer structure forms, and internal layer is the polyurethane sebific duct, skin is woven tube, and woven tube is 1 time structure on woven 1, in use its withstand voltage properties is poor, in addition high-pressure water, therefore, be not suitable for the fire extinguishing of skyscraper, be unfavorable for shortening attack time, cause the loss reduced the person and property.
Summary of the invention
The present invention seeks to propose a kind of super-pressure fire hose that is specially adapted to skyscraper.
Water band of the present invention is comprised of three-decker, and internal layer is the polyurethane sebific duct, and intermediate layer 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 super-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 that on 2, twill weave pipe, the skin under 1 is the twill weave pipe under 2 on 2 owing to adopting intermediate layer, make product also there is certain pliability and wearability when thering is resistance to pressure, be beneficial to turning, knuckle conversion use, conveniently stretch into different parts, to improve the efficiency of fire fighting, also reduce operating personnel's labour intensity, also be beneficial to the service life that extends product.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
As shown in Figure 1, internal layer of the present invention is polyurethane sebific duct 1, the woven twill weave pipe 2 that intermediate layer is 1 undertissue's structure on 2, the woven twill weave pipe 3 that skin is 2 undertissue's structures on 2.
Intermediate layer and outer field woven tube 2,3 all adopt the polyester industrial yarn of high-strength, and internal layer adopts polyurethane adhesive tubing matter as lining, by the method for high temperature heat bonding, two-layer braid and polyurethane sebific duct is bonded together.
Claims (1)
1. super-pressure fire hose, it is characterized in that: described water band is comprised of three-decker, and internal layer is the polyurethane sebific duct, and intermediate layer is the twill weave pipe under 1 on 2, and skin is the twill weave pipe under 2 on 2.
