Abstract

The invention discloses a fire hose with a wear-resistant lining, relates to the technical field of fire hoses, and comprises a fire hose main body, a handle and a connecting flange. The top of the fire hose main body is provided with a handle. The top outer surface of the handle is provided with a connecting flange, the main body of the fire hose includes an outer belt, an inner lining and an active chamber, the inner lining includes a wear-resistant bag and an elastic bag, and the resistant The grinding bag body and the elastic bag body are connected end to end. The invention not only improves the wear resistance of the inner lining of the fire hose, but also reduces the impact of high-pressure water flow on the inner lining of the fire hose through the elastic bag body, and improves the wear resistance of the fire hose. The wear resistance and impact resistance of the inner lining can also enable the fire hose to cool itself in a high temperature environment in the fire scene, which improves the high temperature resistance of the fire hose and makes it convenient for firefighters usage of.

Description

technical field [0001] The invention relates to a fire-fighting hose with a wear-resistant lining, and relates to the technical field of fire-fighting hoses. Background technique [0002] A fire hose is a hose used to transport flame-retardant liquids such as high-pressure water or foam. A traditional fire hose is lined with rubber and wrapped with a linen braid on the outside. Advanced fire hoses are made of polymeric materials such as polyurethane. Both ends of the fire hose have metal connectors that can be connected to another hose to extend the distance or to a nozzle to increase the pressure of the liquid spray. Fire hoses are divided into two types: lined fire hoses and leaking fire hoses. Lined fire hoses include rubber fire hoses, TPU fire hoses, polyester glue-filled hoses, hemp plastic-coated hoses. 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 categ...
