Deformation in journey, and then reduce pressure loss, improve pressure transmission speed simultaneously；It is provided with hole in fixed layer simultaneously, makes
When must vulcanize, hose lining can combine together through fixed layer, it is ensured that not being layered because of fixed layer of hydraulic oil pipe, Yi Mianqiang
Degree reduces.Hydraulic oil pipe pressure transmission speed of the present utility model is fast, and pressure loss is little, and intensity is high.
Preferably, described enhancement layer is two-layer, is provided with mesoglea described in two-layer between enhancement layer.I.e. above-mentioned side
Add one layer of mesoglea, one layer of enhancement layer between enhancement layer and the outer glue-line of case, add between inner glue layer and enhancement layer the most again
One layer of enhancement layer, one layer of mesoglea, realize pressing from both sides between three layers of rubber layer two-layer enhancement layer in a word；Increase mesoglea and enhancing
Layer can improve hydraulic oil pipe intensity further, enables to bear higher pressure.

In glue-line, the inner glue layer of polyester line fixed layer both sides merges in sulfidation, and polyester line fixed layer is fixed on inner glue layer
In, inner glue layer is fixed by polyester line fixed layer simultaneously；Polyester line does not has elasticity, hinders hydraulic oil pipe axial stretching and footpath
To breathing, reduce inner glue layer deformation in hydraulic oil transmittance process, and then reduce pressure loss, improve pressure simultaneously and pass
Pass speed, the most do not affect the normal bending of hydraulic oil pipe.
Preferably, described enhancement layer is steel wire floor.Steel wire floor intensity is high, and network structure is enhancement layer both sides
Rubber layer interpenetrate fusion when sulfuration and provide convenient.
Preferably, described fixed layer, near described inner glue layer inwall, preferably reduces the deformation of inner glue layer, reduces
Pressure loss, improves pressure transmission speed.
This utility model has the advantage that with good effect: owing to this utility model uses as above technical scheme, fixed layer
Hinder inner glue layer deformation in hydraulic oil transmittance process, and then reduce pressure loss, improve pressure transmission speed simultaneously；
It is provided with hole in fixed layer so that during sulfuration, hose lining can combine together through fixed layer, it is ensured that hydraulic oil pipe simultaneously
It is not layered because of fixed layer, in order to avoid intensity reduces.Hydraulic oil pipe pressure transmission speed of the present utility model is fast, pressure loss
Little, and intensity is high.
Except this utility model described above solves the technical problem that, constitutes the technical characteristic of technical scheme and by this
Outside the advantage that the technical characteristic of a little technical schemes is brought, other technologies problem that this utility model can solve, technology
The advantage that the other technologies feature comprised in scheme and these technical characteristics are brought, hereinafter in conjunction with accompanying drawing make into
One step detailed description.
Accompanying drawing explanation
