Problems solved by technology

During the use of the product, in fact, only the inner layer structure plays the role of pressure resistance, and the outer layer structure plays the role of wear resistance, so the pressure resistance value and wear resistance value of the double-layer structure cannot reach the expected effect, and , there may also be friction between the inner and outer layers, increasing the possibility of problems with the fire hose

Embodiment 1

[0020] see figure 1 , a disposable braided double-layer conjoined fire hose, comprising an outer tube blank 1, an inner tube blank 2, and a braided wire layer 3; the outer tube blank 1 and the inner tube blank 2 are braided synchronously, and The braided wire layer 3 is tightly fixed into one body.

[0021] In this embodiment, the braided wire layer 3 is made of the same material as the outer tube blank 1 and the inner tube blank 2 .

[0022] In this embodiment, the outer tube blank 1 and the inner tube blank 2 are made of polyurethane.

[0023] In this embodiment, the sections of the outer tube blank 1 , the inner tube blank 2 , and the braided wire layer 3 are all circular.

[0024] During specific production, the outer tube blank 1 and the inner tube blank 2 are woven synchronously, and are woven synchronously through the braiding wire layer 3 therebetween, and are tightly fixed into one body.

Embodiment 2

[0026] The difference between this embodiment and the first embodiment is that the material of the braided wire layer 3 is different from that of the outer tube blank 1 and the inner tube blank 2 .

[0027] The hose tube blank in this embodiment has two inner and outer layers, and the tube blanks of the inner and outer layers are closely combined to form an inseparable double-layer structure, so that the inner and outer layers look like two layers, but they are actually the same structure, and the degree of fit is very good Well, the fire hose made in this way has the characteristics of small expansion rate and contraction rate, wear resistance and pressure resistance, and zero loss of blasting force value.

Abstract

The invention relates to a fire hose, in particular to a disposable woven double layer integrated fire hose. The disposable woven double layer integrated fire hose comprises an outer layer tube blank,an inner layer tube blank and a woven wire layer; the outer layer tube blank and the inner layer tube blank are synchronously woven and fixed by the woven wire layer between the outer layer tube blank and the inner layer tube blank to form an integration. According to the fire hose, a tube blank consists of the outer layer tube blank and the inner layer tube blank, and the outer layer tube blankand the inner layer tube blank are closely combined together to form an inseparable double layer structure, so that the outer layer tube blank and the inner layer tube blank look like two layers, butare of an integrated structure actually, the goodness of fit is great, and the fire hose prepared by the method has the characteristics of being small in expansion rate and stretching rate and capableof realizing wear resistance, compression resistance and zero waste of bursting force value.

Description

technical field [0001] The invention relates to a fire-fighting hose, in particular to a disposable braided double-layer one-piece fire-fighting hose. Background technique [0002] The fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. The braid layer of the traditional fire hose is mostly plain or twill single-layer structure, which has poor wear resistance and pressure resistance. At present, there are double-layer braided fire hoses on the market, which are made of two layers of braided layers together to form a double-layer structure. Since the two-layer structure is put together later, the diameter of the inner layer must be smaller than the outer layer. The diameter of the structure. In the actual production process, in order to facilitate later fitting, the smaller the diameter of the inner structure, the easier it is to fit, which will inevitably lead to a certain gap between the inner and outer structures. During the...
