Description

Technical Field

[0001] This application relates to the field of PE gas pipes, and in particular to an aging-resistant PE gas pipe. Background Technology

[0002] In the application of PE gas pipes, traditional polyethylene pipes are widely used in gas transmission pipelines due to their good corrosion resistance, strong pressure resistance, and low production cost. However, with the increase of service time, PE gas pipes may age, leading to a decline in their physical properties, which in turn affects the safety and reliability of gas transmission.

[0003] Chinese Patent CN220134926U discloses an aging-resistant PE gas pipe, relating to the field of PE gas pipe technology. This utility model includes a first pipe fitting and a second pipe fitting. One end of the first pipe fitting has a connecting sleeve with a second sealing groove inside. One end of the second pipe fitting has a connector with a second sealing ring that movably inserts into the second sealing groove. A sealing structure is provided at one end of the second sealing groove. Vertical grooves are formed on both sides of the second sealing groove, and a horizontal groove is formed at one end of each vertical groove. The vertical and horizontal grooves are perpendicularly distributed. This utility model, through the setting of a limiting structure and an installation block, solves the problem that existing aging-resistant PE gas pipes, connected by heat fusion, damage the aging-resistant material structure during the heat fusion process, affecting overall aging resistance and resulting in slow connection speed.

[0004] Regarding the aforementioned technologies, the inventors believe that when using PE gas pipes, seals such as sealing rings and support springs may wear or be damaged, requiring replacement of these components, which results in high maintenance and repair costs. Furthermore, gas flow within the pipe generates eddies, leading to uneven flow velocity and airflow resistance, thus affecting gas delivery efficiency. Therefore, an aging-resistant PE gas pipe is proposed to solve the aforementioned problems. Utility Model Content

[0024] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0025] Reference Figures 1-5 An aging-resistant PE gas pipe includes a gas pipe body 1, wherein the gas pipe body 1 includes an inner layer 2, a buffer layer 21, a middle layer 3, an outer layer 31, a connecting pipe 4, and a fixing pipe 41.

[0026] To prevent chemical corrosion from affecting the safety of the gas pipe body 1, the inner layer 2 is fixedly bonded to the inner wall of the buffer layer 21 with an adhesive. The inner layer 2 is made of high-density polyethylene. The inner layer 2 is fixedly bonded to the buffer layer 21 with an adhesive. The inner layer 2 is made of high-density polyethylene, which can effectively resist common chemical corrosion. It is especially suitable for transporting flammable gases such as gas, and avoids the safety of the gas pipe body 1 from being affected by chemical corrosion.

[0027] To reduce deformation or rupture of the gas pipe body 1 caused by external forces, the buffer layer 21 is made of polypropylene. The intermediate layer 3 is placed between the buffer layer 21 and the outer layer 31. The buffer layer 21 can absorb some energy when external pressure or impact occurs, protecting the inner layer 2 and the intermediate layer 3 from damage. Its material is polypropylene, which has good elasticity and toughness, can maintain good mechanical properties at high temperatures, and has strong corrosion resistance to most chemicals. The intermediate layer 3 is located between the buffer layer 21 and the outer layer 31. Its main function is to provide additional protection and structural support, reducing deformation or rupture of the gas pipe body 1 caused by external forces.

[0028] To protect the gas pipe body 1 from physical and chemical damage from the external environment, the intermediate layer 3 is made of polyethylene, and the outer layer 31 is made of polyvinyl chloride. The intermediate layer 3, being made of polyethylene, has strong tensile strength, which can enhance the structural strength of the entire gas pipe body 1. The outer layer 31, being made of polyvinyl chloride, is sturdy and wear-resistant, and has excellent UV resistance and weather resistance, protecting the gas pipe body 1 from physical and chemical damage from the external environment.

[0029] To ensure a secure connection between the gas pipe body 1 sections, a connecting pipe 4 is fixedly installed at one end of the gas pipe body 1, and a fixing pipe 41 is fixedly installed at the other end of the gas pipe body 1. The connecting pipe 4 is threaded onto the inner wall of the fixing pipe 41. The connecting pipe 4 and the fixing pipe 41 are fixedly installed at both ends of the gas pipe body 1 respectively, thus securing the two gas pipe bodies 1. The threaded connection between the connecting pipe 4 and the fixing pipe 41 not only secures the two gas pipe bodies 1 but also facilitates disassembly, ensuring a secure connection between the gas pipe body 1 sections, reducing the risk of loosening and leakage at the joints, and making installation quick and maintenance convenient.

[0030] By setting up an inner layer 2, a buffer layer 21, a middle layer 3, an outer layer 31, a connecting pipe 4, and a fixing pipe 41, the inner layer 2 is made of high-density polyethylene, which can effectively resist common chemical corrosion. The buffer layer 21 can absorb some energy when external pressure or impact occurs. Its material is polypropylene, which has good elasticity and toughness. The middle layer 3 is located between the buffer layer 21 and the outer layer 31. Its main function is to provide additional protection and structural support. Its material is polyethylene, which has strong tensile strength. The outer layer 31 is made of polyvinyl chloride, which is sturdy and wear-resistant. The connecting pipe 4 is threaded to the fixing pipe 41, which fixes the two gas pipe bodies 1 and facilitates disassembly. It can ensure a firm connection between each section of the gas pipe body 1, reduce the risk of loosening and leakage at the joints, and is quick to install and easy to maintain. It solves the technical problem that when using PE gas pipes, the sealing components, such as sealing rings and support springs, are worn or damaged, and the cost of replacing these components is high.

[0031] In order to guide the flow of gas, the gas pipe body 1 is provided with a reinforcement mechanism, which includes a threaded groove 51. The threaded design of the threaded groove 51 guides the flow of gas.

[0032] To improve the stability and reliability of the gas pipe body 1 under external pressure or mechanical impact, the reinforcement mechanism also includes U-shaped grooves 5 arranged in a ring array. The U-shaped grooves 5 are formed on the outer surface of the intermediate layer 3, and the threaded grooves 51 are formed on the inner wall of the inner layer 2. The U-shaped grooves 5 are formed on the outer surface of the intermediate layer 3, and the opening direction is along the Y-axis and perpendicular to the axial direction of the pipe. This ensures that the U-shaped grooves 5 can more effectively distribute pressure and external impact, preventing external loads from acting directly on the core layer of the gas pipe body 1. The thickness of the U-shaped grooves 5 is one-third of the thickness of the intermediate layer 3. While maintaining a certain strength, it can play a buffering role when subjected to external forces. The main function of the U-shaped grooves 5 is to enhance the compressive strength of the gas pipe body 1 through its unique shape, thereby improving the stability and reliability of the gas pipe body 1 under external pressure or mechanical impact. The threaded grooves 51 are formed on the inner wall of the inner layer 2, which can effectively guide the flow of gas in the gas pipe body 1 and prevent uneven airflow or backflow. The thickness of the threaded grooves 51 is one-third of the thickness of the inner layer 2, ensuring that it has sufficient strength to guide the airflow without affecting the overall strength and durability of the gas pipe body 1.

[0033] To prevent gas leakage, a silicone ring 6 is fixedly installed on the outer surface of the connecting pipe 4. The outer side of the silicone ring 6 contacts the outer side of the fixing pipe 41. The connecting pipe 4 and the silicone ring 6 are fixedly installed to secure them. When it is necessary to connect two gas pipe bodies 1, the worker will thread the connecting pipe 4 fixedly installed on one gas pipe body 1 to the fixing pipe 41 on the other gas pipe body 1 until the silicone ring 6 fixedly installed on the connecting pipe 4 contacts the fixing pipe 41, ensuring a tight contact surface. This effectively fills the tiny gaps between the interfaces during connection and prevents gas leakage.

[0034] By setting up a reinforcing mechanism to guide the flow of gas, the main function of the U-shaped groove 5 is to enhance the compressive strength of the gas pipe body 1 through its unique shape. The threaded groove 51 is opened on the inner wall of the inner layer 2, which can effectively guide the flow of gas in the gas pipe body 1 and prevent uneven airflow or backflow. When it is necessary to connect two gas pipe bodies 1, the operator will thread the connecting pipe 4 fixedly installed on one gas pipe body 1 to the fixed pipe 41 on the other gas pipe body 1 until the silicone ring 6 fixedly installed on the connecting pipe 4 contacts the fixed pipe 41 to ensure a tight contact surface. This effectively fills the small gaps between the interfaces during connection, prevents gas leakage, and solves the technical problem that when using PE gas pipes, the gas will generate eddies when flowing in the pipe, resulting in uneven flow velocity and airflow resistance, which affects the gas delivery efficiency.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
