Problems solved by technology

[0004] The purpose of the present invention is to provide a fire hose with anti-corrosion performance lining, to solve the inconvenience proposed in the above background technology to prevent corrosion to the inside of the fire hose layer main body, inconvenient to protect the waterproof film layer, resulting in waterproof film The service life of the layer is shortened. Secondly, it is inconvenient to fix the main body of the fire hose layer and the sprinkler head, resulting in the inability to effectively reduce the impact of the water pressure generated by the water flowing out of the main body of the fire hose layer on the sprinkler head.

Abstract

The invention discloses a fire-fighting hose with an anti-corrosion lining, relates to the technical field of fire-fighting equipment, and comprises a fire-fighting hose layer main body, a water spray head and a water inlet pipe joint. The left side of the fire-fighting hose layer main body is installed on the water spray The right side of the head, the left side of the inlet pipe joint is installed on the right side of the main body of the fire hose layer, and the inside of the main body of the fire hose layer is provided with a waterproof film layer. The fire hose with anti-corrosion performance lining can prevent the interior of the main body of the fire hose layer from being corroded, can protect the waterproof film layer, and can increase the service life of the waterproof film layer, and can make the fire hose layer main body and The sprinkler head is fixed, and effectively reduces the water pressure generated by the water flowing out of the main body of the fire hose layer to the impact of the sprinkler head, which can protect the supporting semi-circular arc and prevent the water pressure from being too high. The arc causes damage and increases the life of the supporting semi-arc.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting hose with an anti-corrosion lining. Background technique [0002] The fire hose is a hose used to transport high-pressure water or foam and other flame-retardant liquids. It is one of the common fire-fighting equipment. The traditional fire hose is lined with rubber and the outer surface is wrapped with linen braid. Advanced fire hose The belt is made of polymeric 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] The fire hoses with anti-corrosion lining on the market are inconvenient to prevent corrosion to the interior of the main body of the fire hose layer, and it is inconvenient to protect the waterproof film layer, resulting in a shorter service life of the waterproof film layer. Seco...
