Problems solved by technology

Due to the large deformation of the end of the catheter after the flaring treatment, cracks are prone to appear, resulting in a decrease in the fatigue performance of the combined catheter, and in terms of sealing performance, due to the processing error of the flare, the phenomenon of leaking, dripping and leaking often occurs
At the same time, the system pipeline composed of flared pipeline connectors has poor structural rigidity, poor axial tensile performance, and low ultimate strength of the pipe, resulting in low working pressure, which cannot meet the application requirements of all aircraft pipelines
[0004] Therefore, it is urgent to realize the conversion and upgrading of the existing aircraft pipeline structure, and avoid the technical defects of the existing flared structure or non-flared structure

Embodiment 1

[0078] see Figure 8 , which shows a structural schematic diagram of another system pipeline based on a rolling combined catheter in an embodiment of the present invention. The system pipeline 800 provides a hydraulic pipeline carrier, transmits pressure medium, and ensures the normal implementation of system functions. At the same time, the flaring is converted to a non-flaring structure, which also reduces the weight of the system, improves the sealing performance of the system, and meets the design requirements of light weight and high pressure. which includes Figure 5 The flareless combination catheter 500 and Figure 6 A flared-flareless combination catheter 600 is shown.

Abstract

The invention provides a system pipeline based on rolling type combined guide pipes, and relates to the technical field of hydraulic pipelines. The system pipeline comprises at least one non-flaring-flaring combined guide pipe and at least one non-flaring combined guide pipe. The non-flaring combined guide pipe comprises a first guide pipe; the first end of the first guide pipe is fixed to a first light straight-through connector in a rolling connection manner; and the second end of the first guide pipe is an extrusion type structure assembly or a sealing type structure assembly or a clamping sleeve type structure assembly. The non-flaring-flaring combined guide pipe comprises a second guide pipe; and the first end of the second guide pipe is fixed to a second light straight-through connector in a rolling connection manner, and the second end of the second guide pipe is assembled with a flat pipe nozzle and a flaring nut in a flaring manner. In the system pipeline, mutual conversion between the flaring combined guide pipe and the non-flaring combined guide pipe can be carried out, the working pressure of a pipeline system is improved, the problems of leakage and dripping generally existing in the current pipeline system are solved, and the sealing performance and the fatigue performance of the pipeline joint are improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic pipelines, in particular to a system pipeline based on a rolling combined conduit and an assembly method thereof. Background technique [0002] At present, domestic aircraft pipelines mainly use flared pipeline connectors. [0003] The structure of the flared pipeline connector is that both ends of the conduit are flared, and the end of the conduit is processed into a certain angle by a flare forming machine, about 74°. Due to the large deformation of the end of the catheter after the flaring treatment, cracks are prone to occur, resulting in a decrease in the fatigue performance of the combined catheter, and in terms of sealing performance, due to the processing error of the flaring, the phenomenon of running, emitting, dripping and leaking often occurs. At the same time, the system pipeline composed of flared pipeline connectors has poor structural rigidity, poor axial tensile performance, an...
