Problems solved by technology

At present, the fire brigade requires that the lighter and lighter the fire hose, the better. However, with the increase of the pressure resistance value of the existing fire hose, its weight also increases accordingly (the current national standard for fire hose stipulates that the maximum The working pressure is 2.5MPa, and higher pressure is often required in actual use, and the increase in pressure according to the existing technology will inevitably cause the weight to exceed the standard), and the weight will not only increase the labor intensity of the firefighters, but also increase the pressure. As a result, the fire fighting plane was delayed, resulting in huge loss of life and property
[0003] In addition, the existing fire hoses will sink underwater due to their high specific gravity during use. In the process of rescue across water bodies or at sea, floating bodies need to be added, which will undoubtedly increase the difficulty and time of rescue, which is not conducive to rescue

Embodiment 1

[0016] This embodiment takes the use of a fire hose with a working pressure of 2.5 MPa and an inner diameter of 65 mm as an example.

[0017] The warp and weft are all made of high-strength high-modulus polyethylene fiber filaments, which are woven into a fire hose through plain weave or twill weave. Leakage lining, the weight of the fire hose produced from this is 215-220 g / m, according to the requirements of the national standard wear-resistant test, the number of wear-resistant times reaches 150 times, and it also has the function of anti-cutting and anti-chemical. The fire hose has light specific gravity and can float on the water.

Embodiment 2

[0019] A layer of wear-resistant and anti-slip layer was added outside the braided layer of the fire hose prepared in Example 1. After the wear test, the number of wear resistance was increased to 190 times, and it also had the effect of anti-skid. The prepared fire hose The belt is light in specific gravity and can float on the water.

Embodiment 3

[0021] This embodiment takes the use of a fire hose with a working pressure of 2.5 MPa and an inner diameter of 80 mm as an example.

[0022] The warp and weft threads are all made of high-strength high-modulus polyethylene fiber filaments, which are woven into a fire hose through plain weave or twill weave. Leakage lining, the weight of the fire hose produced from this is 250-260 g / m, the number of times according to the requirements of the national standard wear-resistant test, the number of wear-resistant times reaches 150 times, and it also has the function of anti-cutting and anti-chemical. The fire hose has light specific gravity and can float on the water.

Abstract

The invention discloses a high-pressure wear-resistant portable fire hose. Warps and wefts are woven to form the high-pressure wear-resistant portable fire hose and made of high-strength high-elasticity module polyethylene fiber materials. The high-pressure wear-resistant portable fire hose has the advantages of light weight, high wear resistance, high pressure resistance and the like, and furtherhas anti-cutting and chemical defense functions.

Description

technical field [0001] The invention relates to a fire-fighting hose, in particular to a high-pressure, wear-resistant and portable fire-fighting hose. Background technique [0002] The fire hose is a hose used to transport high-pressure water or foam and other flame-retardant liquids, and it is one of the necessary fire-fighting appliances. At present, the fire brigade requires that the lighter the fire hose, the better. However, the existing fire hose increases with the increase in pressure resistance, and its weight also increases accordingly (the current national standard for fire hose stipulates that the maximum fire hose The working pressure is 2.5MPa, and higher pressure is often needed in actual use, and the increase in pressure according to the existing technology will inevitably cause the weight to exceed the standard), and the weight will not only increase the labor intensity of the firefighters, but also increase the pressure. Therefore, the firefighting plane w...
