Description

Fire hose

Technical Field

The utility model belongs to the technical field of fire-fighting equipment technique and specifically relates to a fire hose.

Background

Fire hose is a hose used to transport high pressure water or fire-retardant liquids such as foam.

At present, traditional fire hose includes by interior toward the plastic layer and the weaving layer that sets gradually outward, because the weaving layer is woven unreasonablely for the fracture can appear in the weaving layer when fire hose is dragged by fire fighter, this weaving layer tensile is dragged the ability relatively poor, because the fracture appears in the weaving layer, can cause the easy wearing and tearing of plastic layer and ground friction even break, leads to the hosepipe to leak, thereby has shortened life. On the other hand, the water source that fire hose used is often high-pressure rivers, can produce great impact force to it when passing through fire hose, leads to the fire fighter to be difficult to control the water spray direction to fire extinguishing efficiency has been influenced.
