Description

Technical Field

[0001] This utility model relates to the field of high-pressure pipe technology, specifically to a steel wire wound high-pressure pipe. Background Technology

[0002] In industries such as chemical, petroleum, and machinery manufacturing, high-pressure pipeline systems must withstand long-term high pressure, strong corrosion, and complex environments, thus placing extremely high demands on the structural strength, sealing, and corrosion resistance of the pipelines. Traditional high-pressure pipelines typically use a single material, which makes them prone to cracking at weak points in the pipe wall when subjected to high pressure and complex external forces; this significantly affects the service life and safety of the high-pressure pipeline.

[0003] Based on the above, this utility model proposes a high-pressure pipe wound with steel wire, which can effectively solve the above problems. Utility Model Content

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0020] A high-pressure steel wire wound pipe includes an inner tube body 1 made of polyethylene; a steel wire mesh 2 is installed on the outer wall of the inner tube body 1; an outer tube body 3 is provided outside the steel wire mesh 2, and the outer tube body 3 is made of polyvinyl chloride; the outer tube body 3 includes two semi-circular rings 31, which are detachably connected by a connecting mechanism.

[0021] This invention features an inner tube 1 made of polyethylene, which is corrosion-resistant, chemical-resistant, and flexible, making it suitable for transporting liquids or gases. The steel wire mesh 2 on the outer wall of the inner tube 1 enhances the overall structural strength and pressure resistance, enabling it to withstand high-pressure environments. The outer tube 3 is made of polyvinyl chloride, which provides wear resistance, aging resistance, and protection for the internal structure, extending its service life. Additionally, the outer tube 3 includes two semi-circular rings 31 that are detachably connected by a connecting mechanism, facilitating the installation, maintenance, or replacement of internal components and improving operational convenience and maintenance efficiency.

[0022] Detachable outer tube: The outer tube consists of two semi-circular rings that are detachably connected by a connecting mechanism, which facilitates the installation, maintenance or replacement of internal components (such as wire mesh or inner tube), improving operational convenience and maintenance efficiency.

[0023] Furthermore, in another embodiment, flanges 11 are fixedly connected to both ends of the inner tube 1.

[0024] By fixing flanges 11 to both ends of the inner pipe body 1, the flange connection method is mature and reliable, which can realize the rapid and stable connection of high pressure pipe with other equipment or pipelines, and ensure the sealing and firmness of the connection.

[0025] Furthermore, in another embodiment, flexible side plates 21 are fixed to both ends of the wire mesh 2, and connecting seats 22 are fixedly connected to both ends of the flexible side plates 21, and the two connecting seats 22 are fixedly connected by bolts 23.

[0026] By setting up flexible side plates 21, connecting seats 22 and bolts 23, the wire mesh 2 is wound around the outside of the inner pipe body 1 and fixed, which can effectively improve the pressure resistance and deformation resistance of the high-pressure pipe, making the pipe less prone to cracking or deformation when subjected to high pressure, and ensuring the safe operation of the pipe.

[0027] Furthermore, in another embodiment, the connecting mechanism includes a connecting block 32 fixedly connected to one end of the semi-circular ring 31, and a connecting groove 33 opened at the other end of the semi-circular ring 31; a protrusion 321 is fixedly connected to one side of the connecting block 32, and a first inclined surface 322 is provided on the outer side of the protrusion 321; a recess 331 that engages with the protrusion 321 is opened on the inner side of the connecting groove 33, and a second inclined surface 332 that abuts against the first inclined surface 322.

[0028] By setting a connecting mechanism, the protrusion 321 and the recess 331 are engaged and snapped together, and the first inclined surface 322 and the second inclined surface 332 abut against each other, so that the two semi-circular rings 21 are tightly connected, ensuring the structural integrity and sealing of the outer tube 3. This connection method is easy to install. The connection can be completed simply by inserting the connecting block 32 into the connecting groove 33 and adjusting its position appropriately. Disassembly is also relatively convenient and does not require complicated tools.

[0029] Furthermore, in another embodiment, one of the semicircular rings 31 has grooves 34 on both sides for the connecting seat 22 to pass through.

[0030] By setting the groove 34, a passage is provided for the connecting block to pass through, so that the outer tube 3 and the connecting seat 22 of the wire mesh 2 are matched, avoiding interference during installation and ensuring that the components fit together tightly.
