Fire hose with anti-cracking and high-pressure-resistant lining

Abstract

The invention relates to a fire hose with an anti-cracking and high-pressure-resistant lining, and relates to the technical field of fluid conveying. The fire hose comprises a fire hose body, a flame-retardant protective outer layer, a water-pressure-resistant relieving middle layer and an anti-cracking protective inner layer. Transverse wear-resistant strips are fixedly installed on the surface of the fire hose body. Longitudinal wear-resistant strips are fixedly installed on the surface of the fire hose body and located on the transverse wear-resistant strips, the outer wall of the flame-retardant protective outer layer is fixedly installed on the inner wall of the fire hose body, and the left side and the right side of the flame-retardant protective outer layer are fixedly installed onthe inner wall of the fire hose body. The fire hose is ingenious in design, a corrosion-resistant soft layer, a water pressure eradication layer and an anti-cracking outer layer are combined, the problem that when an existing fire hose is used, the interior of the fire hose is likely to crack due to long-term water pressure is conveniently solved, the pressure resistance of the fire hose to waterpressure can be improved, cracking and water leakage in the fire hose are avoided, and the working efficiency of fire-fighting equipment is improved.

Description

technical field [0001] The invention relates to the technical field of fluid transportation, in particular to a fire hose with an explosion-proof and high-pressure resistant lining. Background technique [0002] Fire-fighting water pipes refer to pipeline materials used for fire-fighting, connecting fire-fighting equipment and equipment, and transporting fire-fighting water, gas or other media. Due to special requirements, the thickness and material of the fire pipes and water pipes have special requirements. They are sprayed with red paint to transport fire water. However, due to the unpredictable high heat generated by different environments on the fire scene, some combustion materials will generate high smoke, gas, and radiant heat, which will cause the lining and blank of the fire hose to be detached by heat and be damaged.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a fire-fighting hose with an explosion-proof and high-pressure-resistant lining, one of the purposes of which is to have an anti-corrosion soft layer, a water pressure barrier layer, and an explosion-proof outer layer to solve the problem of existing fire-fighting hoses. When the belt is in use, it is prone to bursting inside the fire hose under long-term water pressure; another purpose is to solve the high heat generated by the different terrains of the fire hose when the existing fire hose is used in most fire places , causing the hose to be burned all the time, causing the main body of the hose to be damaged and destroyed, so that the fire hose can not be restricted by the heat of the fire scene, so that it can resist high temperature, and the hose can be obtained The anti-combustion effect, another purpose is to have a pressure relief layer, a pressure sensing layer, and a pressure relaxation layer, which is convenient to solve the problem that most of the existing fire hoses are used for too long in the fire scene, which will cause the interior to be damaged by water. In order to achieve the time limit that the fire hose can not be impacted by water pressure, so that the interior can be wear-resistant, and the water belt can get the effect of dredging water pressure
