Composite hydraulic oil pipe

Abstract

The invention discloses a composite hydraulic oil pipe. The composite hydraulic oil pipe comprises an oil pipe main body, a high-molecular polymer inner core pipe, a dipped vinylon braided layer and anylon braided double layer; and the oil pipe main body internally comprises the high-molecular polymer inner core pipe, the dipped vinylon braided layer, the nylon braided double layer, a stainless steel wire braided layer and a polyamine outer layer pipe. According to the composite hydraulic oil pipe, by braiding the dipped vinylon braided layer on the outside of the high-molecular polymer innercore pipe, the dipped vinylon braided layer is attached to the inner core pipe more closely, then, the nylon braided double layer is braided on the dipped vinylon braided layer, and finally, the stainless steel wire braided layer is pressed on the outside of the nylon braided double layer; and accordingly, through the layer-by-layer progressive braiding mode, the problem that the braided layer isnot compactly braided on the inner core pipe can be effectively solved, the swelling amount of the oil pipe is decreased, the bursting strength of the hydraulic oil pipe can be greatly improved, thewhole structure is compact, and the practicality is high.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil pipes, in particular to a composite hydraulic oil pipe. Background technique [0002] The hydraulic oil pipes on the market are not suitable for non-mineral brake fluids and mineral brake fluids in the process of application. They have certain limitations in use, and most of the hydraulic oil pipes themselves can only be used in specific environments. The effect of being used in a variety of harsh environments has poor functionality and cannot withstand high burst pressure. SUMMARY OF THE INVENTION [0003] (1) Technical problems solved [0004] Aiming at the deficiencies of the prior art, the present invention provides a composite hydraulic oil pipe, which solves the problem that the existing hydraulic oil pipes on the market are not suitable for non-mineral brake oil and mineral brake oil during the application process, and have certain characteristics during use. Limitations, and most...
