Problems solved by technology

That is, the steel wire is wound on the inner rubber layer. Although this method can achieve a certain strengthening effect; however, the rubber hose is subjected to various pressures during actual use, such as the impact caused by the conveying medium in the inner rubber layer, mechanical pressure or friction, sunlight, rainwater, etc. corrosion etc.
It is easy to make the hose very vulnerable to damage

Abstract

A dense steel wire winding silicone hose relates to the technical field of hoses, in particular to a dense steel wire winding silicone hose. The object of the present invention is to provide a dense steel wire wound silicone hose with strong stability and good tensile performance. The invention provides a dense steel wire wound silicone hose, which is characterized in that: an inner rubber layer is arranged inside, an air cushion layer is arranged outside the inner rubber layer, and the air cushion layer and the inner rubber layer are connected by glue; A middle rubber layer is provided, and a steel wire braid is intertwined outside the middle rubber layer; an outer rubber layer is arranged outside the steel wire braid, an armor layer is arranged outside the outer rubber layer, and a self-healing material is arranged between the outer rubber layer and the armor layer.

Description

technical field [0001] The invention relates to the technical field of hoses, in particular to a dense type steel wire wound silicone hose. Background technique [0002] Hose is a kind of tubular rubber product used to transport gas, liquid, slurry or granular materials. It is composed of inner and outer rubber layer and skeleton layer. The inner rubber layer is used to transport the medium, and the skeleton function is to bear the pressure; the traditional steel wire is wound around the silicone hose, and the general structural skeleton adopts the steel wire layer. That is, the steel wire is wound on the inner rubber layer, although this method can achieve a certain strengthening effect; however, the rubber hose is subjected to various pressures during actual use, such as the impact caused by the conveying medium in the inner rubber layer, mechanical pressure or friction, sunlight, rainwater corrosion, etc. It is easy to make the hose vulnerable to damage.
