[0017] The technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0018] The high pressure-resistant PE reducing straight pipeline structure of the present application comprises a main pipe section 100.

[0019] The main pipe section includes a head pipe section 1 and a tail pipe section 2, which are respectively provided with an inner diameter matched with the pipeline to be connected, thereby forming a different diameter structure, and the main pipe section 100 is internally provided with a reinforcing layer to improve the pressure resistance of the pipeline; meanwhile, the two end pipe section interfaces are provided with a sealing ring assembly, and the outer wall of the main pipe section 100 is uniformly provided with reinforcing ribs 3 to increase the radial strength and deformation resistance of the pipeline, and the side wall of the main pipe section 100 is provided with a plurality of small pressure release holes 6 to relieve pressure and protect the pipeline structure from damage.

[0020] Further, the main pipe section 100 is made of high-strength PE material, preferably high-density polyethylene (HDPE) or ultra-high molecular weight polyethylene (UHMWPE) material, which has excellent corrosion resistance, wear resistance and certain elasticity. The main pipe section 100 includes a head pipe section 1 and a tail pipe section 2, one end of which is designed with a larger inner diameter and the other end with a smaller inner diameter to adapt to the connection requirements of pipelines of different diameters.

[0021] Further, the reinforcing layer provided inside the main pipe section 100 is composed of one or more layers of interwoven fiber materials (such as glass fiber, carbon fiber or aramid fiber). Such materials have the characteristics of high strength and high modulus, which can significantly improve the pressure resistance and deformation resistance of the pipeline. The reinforcing layer and the PE material are tightly combined through a specific process (such as co-extrusion, hot pressing, etc.) to form an integrated pipeline structure, ensuring the firm connection between the reinforcing layer and the base material.

[0022] Further, the sealing ring assembly is arranged at the head pipe section 1 and the tail pipe section 2 of the main pipe section 100. Specifically, the sealing ring assembly includes an elastic sealing ring and a compression ring. The elastic sealing ring is made of a material resistant to high pressure and corrosion to ensure sealing effect under different pressures; the compression ring is fixed to the main pipe section by screw thread or buckle, uniformly pressing the elastic sealing ring to achieve tight sealing.

[0023] Further, the reinforcing ribs 3 are uniformly distributed along the outer wall of the main pipe section 100 to increase the radial strength and deformation resistance of the pipeline. The reinforcing ribs 3 are integrally formed with the main pipe section 100 to ensure the integrity and stability of the structure.

[0024] Further, the head pipe section 1 of the main pipe section 100 is connected with a large flange 5 and the tail pipe section 2 is connected with a small flange 4 for connection with the flanges of adjacent pipelines or equipment. Standard bolt holes are provided on the small flange 4 and the large flange 5 for quick installation and disassembly.

[0025] Further, the side wall of the main pipe section 100 is provided with a plurality of micro pressure release holes 6, which can effectively relieve pressure and protect the pipeline structure from damage when the internal pressure of the pipeline abnormally rises. The size of the pressure release hole 6 is usually small to ensure that it does not significantly affect the fluid transmission performance of the pipeline under normal circumstances, and when the internal pressure of the pipeline abnormally rises, it can allow enough fluid or gas to escape, thereby relieving the internal pressure of the pipeline.

[0026] The high-pressure-resistant PE reducing straight pipeline structure of the utility model is through. Through the design of the reinforcing ribs and the pressure release holes, the structure can remain stable under high pressure, effectively preventing leakage and rupture. At the same time, the reinforcing layer inside the main pipe section further improves the pressure resistance of the pipeline, ensuring the safety and reliability of fluid transmission. The combination of the elastic sealing ring and the compression ring ensures the stable sealing of the pipeline under different pressures. Finally, the flange connection method is adopted, which facilitates the quick installation and maintenance of the pipeline.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
