Description
Technical field
The utility model relates to a kind of hydraulic hose, and more particularly, it relates to a kind of four layers of steel wire-wound hydraulic flexible pipe.
Background technique
Along with the development of China and world's mine engineering machinery, require to improve further to the high-pressure hydraulic rubber hose of carrier fluid pressure power, this sebific duct requires under the high voltage pulse of high-temperature liquid force feed, and in the open under environment, therefore needs longer working life.Therefore, require higher to corresponding each position sizing material of this product and skeletal structure, only have the arrangement of rational properties of rubber and skeleton steel wire, Optimal Development goes out winding angle for the production of the most rational each layer skeleton steel wire of high-performance steel wire-wound hydraulic sebific duct and canoe.
But sebific duct be different from steel pipe with, it has certain deformability, can adapt to the mechanical structure of constantly change, and under the impact of high pressure, sebific duct needs to ensure enough compressive strength on the one hand, need on the other hand enough can deformation behavior.So new technical requirements is proposed to wire rubber pipe, require that steel wire steel pipe has enough flexibility.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of ... ...
For achieving the above object, the utility model provides following technological scheme: a kind of four layers of steel wire-wound hydraulic flexible pipe, comprise the inner glue layer and outer glue-line be made up of synthetic rubber, four layers of steel wire floor be entwined by steel wire spiral are provided with between described inner glue layer and outer glue-line, steel wire floor steel wire Stagger-wrap between adjacent, the angle be wound around between adjacent is 38.4 ° ~ 43.8 °.
The utility model is set to further: the helix angle of described first layer steel wire floor is 60.8 °, and the helix angle of described second layer steel wire floor is 61.1 °, and the helix angle of described third layer steel wire floor is 61.8 °, and the helix angle of described 4th layer of steel wire floor is 62.5 °.
The utility model is set to further: the total thickness of described four layers of steel wire floor and the ratio of internal diameter are 2.15 ~ 2.23.
The utility model is set to further: what described steel wire floor adopted is copper plated steel.
Compared with prior art, the utility model has the advantage of, the winding arrangement mode of the steel wire floor of these four layers of steel wire-wound hydraulic flexible pipes is optimized design, ensures that the flexibility of wire spirally-wound hose is more reasonable, the quality of this product and life-span are greatly improved.Two-layer being interspersed can more have certain restorability in flexibility, allows the angle of interleaved adjacent within the scope of this, and ensure flexible pipe very light in bending process, the spring-back force simultaneously after bending is lower.In the lab, will the torsion of 5N be utilized to bend product, it can bend more than 60 °, and does not produce resilience in 35 °, can have more actual conditions and produce the deformation adapted with it.Find the distortion that can be accepted 1,000,000 times-1,100,000 times by present four layers of steel wire-wound hydraulic flexible pipe by finished product impulse test, ensure the stable use of more than 10 years.By applying the design of this structure, making the steel wire floor structure of four layers of steel wire-wound hydraulic flexible pipe more reasonable, causing the actual life of flexible pipe and resistance to compression effect to be greatly improved, be not only rich in flexibility but also have crushing resistance.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the utility model four layers of steel wire-wound hydraulic hose examples;
Reference character: 1, inner glue layer; 2, steel wire floor; 3, outer glue-line.
Embodiment
With reference to Fig. 1, the utility model four layers of steel wire-wound hydraulic hose examples are described further.
A kind of four layers of steel wire-wound hydraulic flexible pipe, always have three layers, the inside be one deck oil resistant, the inner glue layer 1 made of water-fast synthetic rubber, outermost one deck is the outer glue-line 3 that the synthetic rubber of one deck cream and resistance to weather is made, middle one deck is steel wire floor 2, this steel wire is copper plated steel, copper steel plating can produce better Adhesion force with synthetic rubber, make to keep firm fixing between the two, steel wire floor 2 can not loosen, landing, simultaneously viscous force can allow pipeline more effectively stable in the process of distortion, can not produce relative certain, keeps overall stable.
Be provided with four layers of steel wire floor be entwined by steel wire spiral 2 between inner glue layer 1 and outer glue-line 3, the steel wire floor 2 steel wire Stagger-wrap between adjacent, the angle that between adjacent, steel wire floor 2 is wound around is 40.3 °.The helix angle of described first layer steel wire floor 2 is 60.8 °, and the helix angle of described second layer steel wire floor 2 is 61.1 °, and the helix angle of described third layer steel wire floor 2 is 61.8 °, and the helix angle of described 4th layer of steel wire floor 2 is 62.5 °.Two-layer being interspersed can more have certain restorability in flexibility, allows the angle of interleaved adjacent within the scope of this, and ensure flexible pipe very light in bending process, the spring-back force simultaneously after bending is lower.Find the distortion that can be accepted 1,000,000 times-1,100,000 times by present four layers of steel wire-wound hydraulic flexible pipe by finished product impulse test, ensure the stable use of more than 10 years.And from 50 degree of bending situations, test is passed through for this pipe, acceptable maximum pressure is 41 ~ 45MPa, in the contrast of this pipe fitting with uniform internal diameter, be in absolute advantage.
And the ratio of the total thickness of four layers of steel wire floor 2 and internal diameter is 2.15 ~ 2.23, what choose in the present embodiment be ratio is 2.20, to its pressure test, at the highest pressure that can bear 45MPa of situation that internal diameter is 6.2mm, and can stablize and work on, therefore these four layers of steel wire-wound hydraulic flexible pipes can both have extremely strong flexibility by the Hand of spiral of this angle and Stagger-wrap maintenance pipeline and also have enough anti-pressure abilities, make it in petroleum base and the larger effect of water base middle performance, be widely used.
