Description

Technical Field

[0001] The present application relates to the field of high-pressure pipes, and in particular to a novel polygonal anti-twisting high-pressure pipe. Background Art

[0002] In daily life, high-pressure pipes are mostly used to transport gas or liquid media. Common high-pressure pipes generally include an inner rubber layer, a middle rubber layer, and an outer rubber layer arranged from the inside to the outside. A fiber wire braided layer is arranged between the inner rubber layer and the middle rubber layer, and between the middle rubber layer and the outer rubber layer. The fiber wire braiding can better improve the overall tensile strength.

[0003] However, the inventor believes that this traditional high-pressure pipe will inevitably twist during use, especially when the high-pressure pipe is rolled up or the overall length of the high-pressure pipe is long. On the one hand, the medium transportation in the high-pressure pipe may be affected. On the other hand, after long-term use, the twisted position may be deformed, resulting in the service life of the high-pressure pipe being affected. Utility Model Content

[0004] In order to improve the defects of medium delivery and service life affected by the twisting of the high-pressure pipe.

[0005] The present application provides a novel polygonal anti-twisting high-pressure pipe, which adopts the following technical solution:

[0006] A novel polygonal anti-twisting high-pressure pipe comprises an inner rubber layer, a middle rubber layer and an outer rubber layer which are arranged in sequence from the inside to the outside. A fiber wire braided layer is arranged between the inner rubber layer and the middle rubber layer, and between the middle rubber layer and the outer rubber layer. The outer wall of the outer rubber layer is a regular polygonal structure. At least one surface of the outer wall of the outer rubber layer is provided with a plurality of axially arranged anti-twisting straight wires at intervals. A plurality of anti-twisting components are arranged in the axial direction inside the outer rubber layer, and adjacent anti-twisting components are fitted with each other.

[0007] Optionally, the anti-twist assembly includes an anti-twist main frame and two anti-twist end frames, wherein the two anti-twist end frames are respectively located at two ends of the anti-twist main frame and are staggered with each other.

[0008] Optionally, the anti-twist main skeleton includes two main frames in the form of regular 2n-gons, and a plurality of anti-twist strips arranged at intervals, with both ends of the anti-twist strips respectively fixed to corresponding main frames, and n≥3.

[0009] Optionally, the anti-twist end frame includes m groups of end frames, each of which includes m end brackets and a plurality of anti-twist strips arranged at intervals, one end of the anti-twist strip is fixed to the corresponding end bracket, and the other end is fixed to the corresponding main frame, and m=n.

[0010] Optionally, the end brackets are evenly distributed along the circumferential direction of the main frame, and the position of each end bracket corresponds to one side of the main frame.

[0011] Optionally, the anti-twist strip has a wavy structure.

[0012] To summarize, the present application includes at least one of the following beneficial technical effects: the outer wall of the outer rubber layer is set to a polygonal structure. Due to the characteristics of the polygonal structure itself, it can have a certain anti-twisting performance. At the same time, the anti-twisting straight wire is used to further enhance the overall anti-twisting ability. At the same time, the anti-twisting component in the outer rubber layer is used to make the anti-twisting ability of the entire pipe body better, effectively improving the defects of medium transportation and service life affected by the twisting of the high-pressure pipe.
