Description

Technical Field

[0001] The utility model relates to the technical field of fire hoses, in particular to a high-strength and pressure-resistant fire hose. Background Art

[0002] A fire hose is a flexible pipe used to transport flame-retardant liquids such as high-pressure water or foam. Traditional fire hoses are lined with rubber and wrapped with linen fabric on the outside. Advanced fire hoses are made of polymer materials such as polyurethane. There are metal joints at both ends of the fire hose, which can be connected to another hose to extend the distance or to a nozzle to increase the liquid spray pressure.

[0003] For example, the Chinese utility model provides a "fire hose with high compression resistance" patent number: CN 217622523U, which includes a fire hose body, the inner cavity of which is fixedly connected to a support frame, and the fire hose body includes a protective layer, a polyester anti-scratch layer and a polycarbonate layer, and the protective layer includes a polyurethane layer, a polyvinylidene fluoride rubber layer, a polyester tire layer and a TPU film layer. The utility model has excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance and other characteristics through the setting of the polyester anti-scratch layer. Through the setting of the polyurethane layer, it has good chemical corrosion resistance, oil resistance, wear resistance and adhesion. Through the setting of the polyvinylidene fluoride rubber layer, it solves the problem that the existing fire hose cannot be pressure-regulated during operation and has low compressive strength, which leads to easy bursting during operation.

[0004] Although the above-mentioned documents solve the problem of bursting that is prone to occur during work, the external protective structure of the fire hose is relatively simple and cannot provide multiple layers of protection inside and outside. In addition, the outward impact pressure generated inside is concentrated in one place, which can easily cause the fire hose to rupture and reduce its service life. Utility Model Content

[0007] As a preferred embodiment, the interior of the linen woven material layer consists of a pressure-resistant outer protective layer, an inner lining layer, a reinforcement layer and an inner protective layer; the inner lining layer is wrapped inside the pressure-resistant outer protective layer, the inner lining layer is wrapped inside the reinforcement layer, and the inner protective layer is wrapped inside the reinforcement layer.

[0008] As a preferred solution, the particles inside the impact-resistant particle layer are evenly distributed outside the fire hose body and are arranged in a ring shape.

[0009] As a preferred solution, the polyester tire cloth layer is wrapped around the outside of the fire hose body in an annular shape, and the thickness of the polyester tire cloth layer is two centimeters.

[0010] As a preferred solution, anti-punching mesh belts are evenly distributed inside the inner protective layer, and the anti-punching mesh belts are double-layered.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model can further improve the overall compression resistance of the exterior of the fire hose by adding different compression-resistant materials inside the flax woven material layer, and the other compression-resistant materials and stamping-resistant materials wrapped inside can form a multi-layer protection, and enhance the external stamping resistance and anti-fracture performance, so that the fire hose will not break when subjected to severe extrusion or stamping, and the integrity of the fire hose is guaranteed, thereby extending its service life.
