Embodiment Construction

[0013] like Figure 1-Figure 2 As shown, a fire hose includes a polyurethane layer 1, an aramid fabric layer 2, a glass fiber layer 3, a white latex 4, a polyvinyl chloride layer 5, a graphene layer 6 and a linen woven cloth 7. The polyurethane layer 1 , aramid fabric layer 2, glass fiber layer 3, white latex 4, polyvinyl chloride layer 5, graphene layer 6 and linen woven cloth 7 are arranged from inside to outside in turn, and the graphene layer 6 is coated on polyvinyl chloride On the surface of layer 5, the polyurethane layer 1, the aramid fabric layer 2 and the glass fiber layer 3 are glued and connected in sequence, and four reinforcing ribs 8 are symmetrically arranged in the polyurethane layer 1, and the reinforcing ribs 8 are integrated with the polyurethane layer 1. Formed connection, the outer side of the linen woven cloth 7 is provided with an annular anti-skid ring 9 .

[0014] The surface of the anti-skid ring 9 is arranged in an outwardly convex arc. The anti-s...

Abstract

The invention discloses a fire-fighting water hose which comprises a polyurethane layer, an aramid fabric layer, a glass fiber layer, white latex, a polyvinyl chloride layer, a graphene layer and flax woven fabric; the polyurethane layer, the aramid fabric layer, the glass fiber layer, the white latex, the polyvinyl chloride layer, the graphene layer and the flax woven fabric are sequentially arranged from inside to outside; the graphene layer is coated on the surface of the polyvinyl chloride layer; the polyurethane layer, the aramid fabric layer and the glass fiber layer are sequentially in gluing connection; four reinforcing ribs are symmetrically arranged in the polyurethane layer; the reinforcing ribs are integrally molded and connected with the polyurethane layer; and a ring-shaped anti-sliding ring is arranged at the outer side of the flax woven fabric. The fire-fighting water hose disclosed by the invention is high in structural strength, is not liable to damage, is long in service life, and has an anti-sliding function.

Description

technical field [0001] The present invention relates to a fire hose. Background technique [0002] Fire hoses are hoses used to transport fire retardant liquids such as high pressure water or foam. Traditional fire hoses are lined with rubber and wrapped in woven linen on the outside. Advanced fire hoses are made of polymeric materials such as polyurethane. Fire hoses are classified into lined and unlined. Lined fire hoses include cotton, nylon lined hoses, polyester glue-filled hoses, and hemp plastic-coated hoses. Unlined hose with cotton hose, linen hose, ramie hose. According to the working pressure, it is divided into four categories: 0.8MPa, 1.0MPa, 1.3MPa, and 1.6MPa. According to the diameter, it is divided into four categories: 50, 65, 80 or 75, 90 mm. According to the weaving method, it is divided into two types: plain weave and twill weave. The length of each section of the hose is generally specified as 20 meters. . Management aspects. It is necessary to...
