Disposable woven double layer integrated fire hose and manufacture method thereof

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...

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
