Description

Technical Field

[0001] The utility model relates to a pipeline, in particular to a highly weather-resistant and corrosion-resistant pipeline applied to the pipeline field. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids or fluids with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump, boiler, etc., it flows from the high-pressure part of the pipeline to the low-pressure part, or it can also be transported by the pressure or gravity of the fluid itself. The uses of pipelines are very extensive, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industries.

[0003] When connecting and fixing pipelines, usually threaded connections or flange plates are used for connection and fixing. After long-term use, this method may cause loosening or rusting during use, thus affecting the connection sealing effect. When the pipeline connection sealing effect is poor, seepage and water leakage will occur, making the pipeline no longer a closed system, and pollutants outside the pipeline will enter the pipeline interior from the gaps, thereby accelerating the corrosion of the pipeline. Content of the Utility Model

[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that the pipeline interface is fixed by threads or flange plates, which may cause loosening or rusting during use, resulting in the pipeline no longer being closed, and external pollutants entering the pipeline to accelerate the corrosion of the pipeline.

[0005] To solve the above problems, the utility model provides a highly weather-resistant and corrosion-resistant pipeline, which includes two pipeline bodies. One end of each of the two pipeline bodies corresponding to each other is provided with a limiting groove. A fixing joint is inserted into the two limiting grooves together. Two limiting rings are fixedly sleeved on the outer surface of the fixing joint. Two fixing plates are fixedly connected to the outer surface of the limiting ring. A fixing ring is fixedly sleeved on the outer surface of the pipeline body near the fixing joint. Two accommodating grooves corresponding to the two fixing plates respectively are formed on the surface of the fixing ring. Sliders are slidably connected to the accommodating grooves through two sliding grooves. One ends of the two sliders corresponding to each other are fixedly connected to form an insertion plate. One end of each of the two fixing rings away from each other is rotatably connected to an adjusting ring. Two adjusting grooves are formed on the surface of the adjusting ring. One end of the insertion plate away from the limiting ring is fixedly connected to a sliding rod, and the end of the sliding rod away from the insertion plate movably penetrates through the adjacent adjusting groove.

[0006] In the above-mentioned highly weather-resistant and corrosion-resistant pipeline, during use, the two pipelines are not connected by flange plates or threads, effectively avoiding the loosening or rusting of the pipeline interface in the later stage, reducing the occurrence of pipeline seepage and water leakage, and preventing external pollutants from entering the pipeline interior, thereby delaying the corrosion of the pipeline.

[0007] As a further improvement of the present application, positioning grooves I that cooperate with the limiting grooves are drilled at both the front and rear ends of the fixed joint, positioning grooves II are drilled on both the front and rear inner walls of the fixed joint, and the inner diameter of the fixed joint is the same as that of the pipe body.

[0008] As a further improvement of the present application, the longitudinal section of the fixing plate is arc-shaped, and one end of the two fixing plates corresponding to each other fits with the end of the two inserting plates away from each other. A slot that cooperates with the inserting plate is drilled on the surface of the fixing plate.

[0009] As a further improvement of the present application, the adjusting groove is an arc-shaped groove, and the distance between one end of the inner wall of the adjusting groove and the central axis of the adjusting ring is less than the distance between the other end of the inner wall of the adjusting groove and the central axis of the adjusting ring.

[0010] As a further improvement of the present application, two arc-shaped holding plates are fixedly connected to the ends of the adjusting ring away from each other. A plurality of convex blocks are fixedly connected to the surface of the holding plates, and one end of the two holding plates corresponding to each other fits with the outer surface of the pipe body.

[0011] As another improvement of the present application, the pipe body includes a ceramic pipe and a heat insulation pipe fixedly sleeved on the outer surface of the ceramic pipe. A metal pipe is fixedly sleeved on the outer surface of the heat insulation pipe, and a plurality of heat dissipation fins are fixedly connected between the metal pipe and the heat insulation pipe.

[0012] As a supplement to another improvement of the present application, the heat dissipation fins are distributed in a circumferential array around the central axis of the ceramic pipe, and both the front and rear ends of the heat dissipation fins are fixedly connected to the circumferential inner wall of the metal pipe.

[0013] In summary, during use, insert the two pipe bodies into the fixed joint, hold the holding plates and rotate the adjusting ring, so that the sliding rod moves along the arc of the adjusting groove, driving the inserting plate to move towards the fixing plate until the inserting plate penetrates the slot of the fixing plate, thereby fixing the pipe body and the fixed joint. There is no need to connect through threads, bolts or flange plates, thus effectively avoiding the phenomenon of loosening or rusting at the pipe interface in the later stage, reducing the occurrence of pipe leakage due to penetration, effectively preventing external pollutants from entering the pipe interior, and thus delaying the corrosion of the pipe.

Specific embodiments

[0022] The following will describe in detail the two embodiments of the present application with reference to the accompanying drawings.

[0023] The first embodiment:

[0024] Figure 1 , Figure 2 and Figure 3 show: A highly weather-resistant and corrosion-resistant pipeline includes two pipeline bodies 1. Limit grooves 2 are respectively drilled at one end of the two pipeline bodies 1 corresponding to each other. A fixed joint 3 is inserted into the two limit grooves 2 together. Positioning grooves 1 for cooperating with the limit grooves 2 are respectively drilled at the front and rear ends of the fixed joint 3. Positioning grooves 2 are respectively drilled on the front and rear inner walls of the fixed joint 3. The limit groove 2 divides the end of the pipeline body 1 into two pipe bodies with different diameters. The inner pipe body is located in the positioning groove 2, and the outer pipe body is located in the positioning groove 1, so that the pipeline body 1 and the fixed plug 3 are inserted into each other. The inner diameter of the fixed joint 3 is the same as the inner diameter of the pipeline body 1, so that the pipeline body 1 and the fixed joint 3 are completely matched, and the flow of the liquid inside the pipeline body 1 is not hindered during use.

[0025] Figure 4It is shown that: Two limit rings 4 are fixedly sleeved on the outer surface of the fixed joint 3. Two fixing plates 5 are fixedly connected to the outer surface of the limit ring 4. A fixing ring 6 is fixedly sleeved on the outer surface of the pipe body 1 near one end of the fixed joint 3. Two accommodating grooves 7 corresponding to the two fixing plates 5 respectively are formed on the surface of the fixing ring 6. A slider 9 is slidably connected in the accommodating groove 7 through two sliding grooves 8. One ends of the two sliders 9 corresponding to each other are fixedly connected together to form an insertion plate 10. The sliding grooves 8 and the sliders 9 force the insertion plate 10 to move longitudinally only. Rotating connection parts 11 are respectively arranged at one ends of the two fixing rings 6 away from each other. Two adjusting grooves 12 are formed on the surface of the rotating connection part 11. One end of the insertion plate 10 away from the limit ring 4 is fixedly connected to a sliding rod 13. One end of the sliding rod 13 away from the insertion plate 10 movably penetrates through the adjacent adjusting groove 12. The adjusting groove 12 is an arc-shaped groove, and the distance between one end of the inner wall of the adjusting groove 12 and the central axis of the rotating connection part 11 is less than the distance between the other end of the inner wall of the adjusting groove 12 and the central axis of the rotating connection part 11. Rotation of the rotating connection part 11 can drive the rotation of the adjusting groove 12, and the sliding rod 13 generates displacement under pressure, so that the insertion plate 10 moves up and down. The longitudinal section of the fixing plate 5 is arc-shaped, and one ends of the two fixing plates 5 corresponding to each other are in contact with one ends of the two insertion plates 10 away from each other. A slot for cooperating with the insertion plate 10 is formed on the surface of the fixing plate 5. The insertion plate 10 is inserted into the slot on the fixing plate 5, so as to fix the limit ring 4 and the fixing ring 6, and further fix the pipe body 1 and the fixed joint 3. Two arc-shaped holding plates 14 are fixedly connected to one ends of the two rotating connection parts 11 away from each other. A plurality of bumps are fixedly connected to the surface of the holding plate 14, which is convenient for the staff to rotate the rotating connection part 11. One ends of the two holding plates 14 corresponding to each other are in contact with the outer surface of the pipe body 1.

[0026] During use, insert the two pipe bodies 1 into the fixed joint 3, hold the holding plate 14 and rotate the rotating connection part 11, so that the sliding rod 13 moves along the radian of the adjusting groove 12, driving the insertion plate 10 to move towards the fixing plate 5 until the insertion plate 10 penetrates through the slot of the fixing plate 5, thereby fixing the pipe body 1 and the fixed joint 3. There is no need to connect through threads, bolts or flange plates, effectively avoiding the loosening or rusting of the pipe interface in the later stage, reducing the occurrence of pipe penetration and water leakage, and effectively preventing external pollutants from entering the pipe interior, thereby delaying the corrosion of the pipe.

[0027] The second embodiment:

[0028] On the basis of the first embodiment, a ceramic pipe 15, a heat insulation pipe 16, a metal pipe 17 and a heat sink 18 are newly added, and the rest is the same as the first embodiment.

[0029] Figure 5 and Figure 6It is shown that the pipeline body 1 includes a ceramic pipe 15 and a heat insulation pipe 16 fixedly sleeved on the outer surface of the ceramic pipe 15. A metal pipe 17 is fixedly sleeved on the outer surface of the heat insulation pipe 16. A plurality of heat dissipation fins 18 are fixedly connected between the metal pipe 17 and the heat insulation pipe 16. The heat dissipation fins 18 are distributed in an annular array around the central axis of the ceramic pipe 15. Both the front and rear ends of the heat dissipation fins 18 are fixedly connected to the annular inner wall of the metal pipe 17.

[0030] During use, the ceramic pipe 15 improves the corrosion resistance of the pipeline body 1 in environments such as high temperature, acid, alkali, and steam, as well as the performance of wear resistance and fatigue corrosion resistance. The heat insulation pipe 16 and the heat dissipation fins 18 improve the weather resistance of the pipeline body 1 in a high-temperature state, and can improve the heat dissipation efficiency of the pipeline body 1. The metal pipe 17 has good corrosion resistance and high strength, and can maintain the surface color and quality for a long time under harsh climate conditions.

[0031] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the protection scope is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
