Abstract
The utility model belongs to the field of hydraulic rubber ducts, and disclosed a hydraulic rubber duct with a flat steel wire braiding layer, and the hydraulic rubber duct is optimal in design. The hydraulic rubber duct comprises an inner rubber layer, the steel wire braiding layer and an outer rubber layer, wherein the inner rubber layer, the steel wire braiding layer and the outer rubber layer are laminated sequentially through gluing layers, the steel wire braiding layer comprises a plurality strands of steel wires spirally braided and wound on the gluing layer between the inner rubber layer and the steel wire braiding layer, and each steel wire strand comprises a plurality of juxtaposed and parallel steel wires. The steel wire in the steel wire braiding layer is flat, and the cross section of the steel wire is flat. Each flat steel wire has two mutual parallel planes and arc edges connecting the two ends of the planes. The hydraulic rubber duct employs flat steel wires. Compared with a circular steel wire, the flat steel wires have two parallel planar portions, and the contact area between the steel wire braiding layer and the adjacent layers is greater. The attaching degree is high, and the interlayer bonding force is great.
Description
Technical field
The utility model belongs to hydralic hose field, is specifically related to a kind of hydralic hose with flat Steel Wire Braid, and it is widely used in the hydraulic pressure such as engineering machinery, mining machinery assembly guard system.
Background technique
Hydralic hose is the key element of construction machinery hydraulic system, and in case history, the accident that sebific duct explosion occurs due to sebific duct quality dissatisfaction has report more, high-pressure rubber pipe explosion, after hydraulic oil ejection, form the inflammable gas mixing, easily initiation fire, causes great economic loss.
In use often there is seepage, crackle in hydralic hose, the fault such as break, get loose, when engineering is used, because hydralic hose is not maintainable product,, there is again same fault in the hydralic hose that measure that therefore occurs to solve after above-mentioned fault more renews after use.Getting loose or breaking of hydralic hose, causes hydraulic fluid leak, not only wastes hydraulic oil, befouling environment, and affects the efficiency of construction of engineering machinery, even has an accident, and jeopardizes the safety of people, machine.The reliable quality of hydralic hose is the prerequisite of safety, High-efficient Production, and therefore, the development with the hydralic hose of optimal design structure is necessary.
Model utility content
The purpose of this utility model is the deficiency for existing high pressure steel wire braiding hydralic hose, provide a kind of optimal design, structure has the hydralic hose of flat Steel Wire Braid.
The purpose of this utility model is achieved through the following technical solutions, there is the hydralic hose of flat Steel Wire Braid, comprise: inner glue layer, Steel Wire Braid and outer glue-line, inner glue layer, Steel Wire Braid and outer glue-line are by the stratiform combination successively of gluing layer, Steel Wire Braid is compiled spiral winding on the gluing layer between inner glue layer and Steel Wire Braid mutually by Steel Wire Strand, in Steel Wire Strand, per share steel wire comprises many side by side and the steel wire being parallel to each other, in Steel Wire Braid, steel wire is flat, the sectional shape of steel wire is flat, described flat steel wire has two planes that are parallel to each other and the arcuation edge that is connected plane two ends.
As optimal design of the present utility model, the interplanar perpendicular distance that flat steel wire two is parallel to each other is 0.21-0.23mm, and the horizontal edge length of two planes that are parallel to each other is 0.33-0.34mm.
According to the performance requirement of hydralic hose, described Steel Wire Braid can be one deck, two-layer or multilayer.
54 ° 44 of the helix angle of the Steel Wire Strand of compiling mutually in Steel Wire Braid '.
Compared with prior art, usefulness of the present utility model is:
In the utility model structure, adopt flat steel wire, compared with traditional Round Steel Wire, flat steel wire has two planar sections that are parallel to each other, and the area of contact between Steel Wire Braid and adjacent layer is large, and laminating degree is high, and interlayer combination force is strong.
In addition, the helix angle of the Steel Wire Strand of compiling mutually in Steel Wire Braid is 54 ° 44 ', this angle is the optimized angle of equilibrium, sebific duct its length and external diameter under working pressure are all remained unchanged, and possess good interfacial bonding strength, high resistance to pulse performance, good bending property, bending radius is little, has good flexible.The design of the utility model structure has strengthened the working life of hydralic hose greatly.
