Embodiment Construction

[0017] As shown in the figure, reference number 1 is a high-pressure hydraulic reinforced hose, at least one layer of steel wire layer 2 composed of high tensile strength steel wire, the high tensile strength material has a high tensile strength of 2750~3050Mpa, in the preferred embodiment , preferably high-tensile steel, at least one layer of several continuous curved steel wires wound around an inner hose 3 made of a flexible material, the flexible material of the inner hose can be rubber or polymeric plastics (such as industrial nylon formula plastic). The layer of steel wire 2 defines at least one reinforcement layer 4 covering at least 80% of the outer surface 3a of the inner hose 3 .

[0018] According to the invention, the preferred form to be formed is figure 1 shape, characterized by a cross-section with two longer edges, concavity of a first radius R1 toward the center of a single wire, and two shorter edges perpendicular to the milling according to a second radius ...

Abstract

The present invention relates to a hydraulic hose, in particular a high-pressure hydraulic reinforced hose, comprising an inner-layer hose structure made of flexible material to be reinforced, at least a group of several steel cables made of high-tensile strength material, a group of the steel cables made of high-tensile strength material is winded in the inner-layer hose structure, the several steel cables made of high-tensile strength material form at least a reinforced layer, which covers a least 80% area of outer surface of the inner-layer hose structure. The invention has advantages of: high structure compactibility, high stability and flexibility of torsion, high flexibility in high pressure difference between inside and outside, in addition, the steel wires have greater filling factor, reduced reinforced thickness, anti-abrasion, long service life, may not effect explosion and pulse resistance, and need few material.

Description

technical field [0001] The invention relates to a hydraulic hose, in particular to a high-pressure hydraulic reinforced hose reinforced by at least one layer of steel wire. Background technique [0002] It is well known that the demand for high pressure hydraulically reinforced hose continues to increase. In fact, hydraulic hoses are widely used in hydraulic systems in industry and in any other field. Regardless of the occasions where the pipe body is required to withstand internal or external high pressure, or where there is no hydraulic action in the pipe body, especially in the environment where the pipe body is required to withstand high pressure differences between the inside and outside, while maintaining sufficient flexibility, the hydraulic hose can play its role play an important role. Due to this special functional requirement, the design of the hydraulic hose must meet: try to ensure a tight internal structure, and increase the number of reinforcing steel wires ...
