Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipes, in particular to a corrosion-resistant thermal insulation pipe. Background Art

[0002] Insulated pipes refer to pipes used in industries such as industry and construction to maintain a stable temperature of the medium inside the pipes. The design of insulated pipes needs to consider factors such as the pipe material, working environment temperature, and medium temperature to ensure that the medium transported by the pipe will not be affected by temperature changes during transportation.

[0003] Most of the existing insulated pipes often achieve insulation effects by wrapping insulation materials on the outer layer of the pipes. However, they are easily affected by the environment, causing them to fall off and corrode, resulting in poor insulation effects, affecting the service life of the pipes, which is not worth the cost. In addition, the connections between pipes are often installed by fastening with bolts and nuts. Specific tools are required for assistance during installation, and the installation process is relatively cumbersome. Some pipes are installed through flanges. Although the connection strength is high, the installation process also requires tightening bolts, which affects work efficiency to a certain extent.

[0004] Therefore, the utility model provides a corrosion-resistant heat-insulating pipeline to solve the problems raised in the above background technology. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a corrosion-resistant heat-insulating pipe, in which a first connecting port and a second connecting port are connected and fastened by a connecting mechanism, and different interlayers in the pipe provide the pipe with corrosion-resistant and heat-insulating functions.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A corrosion-resistant heat-insulating pipeline, comprising a first connection port and a second connection port, wherein a first pipeline is fixedly connected to one side of the first connection port, and a second pipeline is fixedly connected to the other side of the second connection port, an inner protective layer is fixedly arranged inside the first pipeline and the second pipeline, an outer protective layer is fixedly arranged outside the first pipeline and the second pipeline, a corrosion-resistant layer is fixedly arranged inside the two outer protective layers, and a heat-insulating layer is fixedly arranged inside the two corrosion-resistant layers;

[0008] A connecting mechanism is provided between the first connecting port and the second connecting port, and the connecting mechanism includes four connecting blocks, four compression springs, four springs, four limit blocks, four trapezoidal blocks, four first cylinders, four fixing blocks and four second cylinders;

[0009] Through the above technical scheme, the first pipeline and the second pipeline are both provided with an outer protective layer to reduce the damage to the pipeline by the external environment, the corrosion-resistant layer can resist the corrosive environment, the inner protective layer can provide protection for the medium transported inside the pipeline, and the thermal insulation layer can maintain the constant temperature inside the pipeline. The connection between the pipelines is achieved through the connecting block, compression spring, spring, limit block, trapezoidal block, first cylinder, fixed block and second cylinder in the connecting mechanism.

[0010] Further, the four compression springs are fixedly arranged on one side of the first connecting port on two opposite sides, the four connecting blocks are fixedly arranged on the four compression springs on two opposite sides, the four springs are fixedly arranged on one side of the first connecting port on two opposite sides, the four limit blocks are fixedly arranged on the four springs on two opposite sides, the four trapezoidal blocks are fixedly arranged on the output ends of the four first cylinders on two opposite sides, and the four first cylinders are fixedly arranged on one side of the first connecting port on two opposite sides;

[0011] Through the above technical solution, when the first connecting port and the second connecting port are connected, the connecting block is pushed and squeezed by the other side of the second connecting port, so that the compression spring connected to the connecting block is forced to shrink, causing the connecting block to slide downward, and at the same time, the limit block inside the first connecting port is squeezed and squeezes the spring to shrink it. When reaching the preset position, the spring is affected by the elastic force and pushes the limit block, causing the limit block to squeeze the trapezoidal block at the output end of the first cylinder.

[0012] Furthermore, the four second cylinders are fixedly arranged at one side of the first connecting port at two opposite sides, and the four fixing blocks are fixedly arranged at the output end of the second cylinder at two opposite sides;

[0013] Through the above technical solution, when the airflow enters the interior of the second cylinder, it stretches out, causing the fixing block to be embedded in the interior of the first connecting port, thereby achieving a firm connection.

[0014] Further, a sealing ring is fixedly provided on one side of the second connection port, and a sealing ring is fixedly provided on the inner side of the second connection port;

[0015] Through the above technical solution, when the connection is made, the sealing ring and the sealing ring will be squeezed to cause them to deform and fill the gap, thereby ensuring a tight seal of the pipeline connection.

[0016] Furthermore, the first connection port and the second connection port are both provided with a plurality of circular grooves on their exteriors, a protective ring is slidably provided on the exterior of the second connection port, and a plurality of limiting balls are fixedly provided inside the protective ring;

[0017] Through the above technical solution, when the first connection port is connected to the second connection port, the protective ring outside the second connection port is pushed to reach a predetermined position, and the limiting ball fits into the circular groove, thereby enhancing the stability between the connection ports.

[0018] Furthermore, the two corrosion-resistant layers are made of glass fiber reinforced plastic, and the two thermal insulation layers are made of polyurethane;

[0019] Through the above technical solution, the glass fiber reinforced plastic has corrosion resistance and can prevent corrosion factors from damaging the pipeline, and the polyurethane material has thermal insulation properties and can reduce heat loss inside the pipeline.

[0020] Furthermore, the two outer protective layers are made of aluminum alloy, and the two inner protective layers are made of polytetrafluoroethylene;

[0021] Through the above technical solution, the aluminum alloy material has high strength and can resist external physical impact to ensure the stability of the pipeline structure. The polytetrafluoroethylene material has stability and can prevent the conveying medium from corroding and wearing the inner wall of the pipeline.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model proposes a corrosion-resistant heat-insulating pipe. When connected, the thrust of the second connecting port will act on the connecting block, causing the connecting block to move downward and squeeze the connected compression spring to shrink it. At the same time, the limit block is also squeezed, causing the spring connected to it to shrink. When the two connecting ports reach the set position, the spring will react to the limit block due to its own elasticity, driving the limit block to apply force to the trapezoidal block on the first cylinder, causing it to transfer the internal gas of the first cylinder to the second cylinder, prompting the fixed block on the second cylinder to extend, and finally embed it into the first connecting port, so that the connection between the pipes is stable, the installation operation process is simple, and no specific installation tools are required.

[0024] 2. The utility model proposes a corrosion-resistant heat-insulating pipeline, which has multiple layers of different structures. The aluminum alloy outer protective layer is responsible for resisting the physical impact and chemical corrosion of the external environment. The corrosion-resistant layer adopts glass fiber reinforced plastic to enhance the resistance of the pipeline to various corrosive substances. The polyurethane insulation layer can effectively prevent heat loss and maintain the internal temperature of the pipeline stable. The inner protective layer is made of polytetrafluoroethylene material with excellent wear resistance, corrosion resistance and lubrication performance, which is beneficial to the smooth flow of the medium inside the pipeline. The multiple layers of different structures increase the service life of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-5 , an embodiment provided by the utility model:

[0034] A corrosion-resistant heat-insulating pipeline, comprising a first connecting port 8 and a second connecting port 9, wherein a first pipeline 1 is fixedly connected to one side of the first connecting port 8, and a second pipeline 3 is fixedly connected to the other side of the second connecting port 9, inner protective layers 6 are fixedly arranged inside the first pipeline 1 and the second pipeline 3, outer protective layers 4 are fixedly arranged outside the first pipeline 1 and the second pipeline 3, corrosion-resistant layers 5 are fixedly arranged inside the two outer protective layers 4, heat-insulating layers 7 are fixedly arranged inside the two corrosion-resistant layers 5, the two corrosion-resistant layers 5 are made of glass fiber reinforced plastic, the two heat-insulating layers 7 are made of polyurethane, the two outer protective layers 4 are made of aluminum alloy, and the two inner protective layers 6 are made of polytetrafluoroethylene;

[0035] The first pipe 1 and the second pipe 3 are respectively provided with a first connection port 8 and a second connection port 9 on one side, so as to facilitate quick splicing and sealed connection between the pipes. The outer protective layer 4 is made of aluminum alloy and fixed to the outermost part. It has the characteristics of high strength, corrosion resistance and light weight, and can effectively resist external physical impact and chemical erosion, and ensure the stability and long-term use of the overall structure of the pipe. The corrosion-resistant layer 5 is made of glass fiber reinforced plastic, which has high strength and excellent corrosion resistance, and can further prevent the damage of various corrosion factors to the pipe in harsh environments. The thermal insulation layer 7 is made of polyurethane material, which is famous for its excellent thermal insulation performance, can effectively reduce heat loss, maintain the internal temperature of the pipe stable, and save energy. The inner protective layer 6 is made of polytetrafluoroethylene, which has excellent chemical stability, wear resistance and self-lubrication, and can effectively prevent the corrosion and wear of the inner wall of the pipe by the conveying medium, and ensure the cleanliness and life of the inside of the pipe.

[0036] A connecting mechanism 14 is provided between the first connecting port 8 and the second connecting port 9. The connecting mechanism 14 includes four connecting blocks 1401, four compression springs 1402, four springs 1403, four limit blocks 1404, four trapezoidal blocks 1405, four first cylinders 1406, four fixing blocks 1407 and four second cylinders 1408. The four compression springs 1402 are fixedly arranged on one side of the first connecting port 8 on opposite sides of two of each other, the four connecting blocks 1401 are fixedly arranged on the opposite sides of two of each of the four compression springs 1402 on opposite sides of two of each other, and the four springs 1403 are fixedly arranged on one side of the first connecting port 8 on opposite sides of two of each other. The four limit blocks 1404 are fixedly arranged on the opposite sides of the four springs 1403, the four trapezoidal blocks 1405 are fixedly arranged on the output ends of the four first cylinders 1406, the four first cylinders 1406 are fixedly arranged on the inside of the first connecting port 8 on one side on the opposite sides of the four two-two cylinders 1408, the four second cylinders 1408 are fixedly arranged on the inside of the first connecting port 8 on one side on the opposite sides of the four two-two fixed blocks 1407 are fixedly arranged on the output ends of the second cylinders 1408 on the opposite sides of the four two-two fixed blocks, a sealing ring 11 is fixedly arranged on one side of the second connecting port 9, and a sealing ring 13 is fixedly arranged on one side of the second connecting port 9 on the inside;

[0037] When the pipeline is connected, the first connecting port 8 is docked with the second connecting port 9, and the force of the second connecting port 9 will act on the connecting block 1401 inside the first connecting port 8, so that the connecting block 1401 moves downward along a predetermined trajectory under pressure. At this time, the compression spring 1402 connected to the connecting block 1401 is subjected to pressure and compressed accordingly. At the same time, the limit block 1404 located inside the first connecting port 8 will also be squeezed due to the docking action, thereby prompting the spring 1403 connected thereto to shrink synchronously. Once the connection position reaches a preset state, the spring 1403 begins to expand with its own resilience, thereby driving the limit block 1404 to move toward the output end of the first cylinder 1406, and the connecting block 1401 will block the limit block 1404, so that it keeps squeezing the trapezoidal block 1405. At this time, the first cylinder 1406 inside the second connecting port 9 is connected to the second cylinder 1408 through the air pipe, and as the airflow flows from the first cylinder 1406 to the second cylinder 1408, the fixed block 1407 at the output end of the second cylinder 1408 is extended so that the fixed block 1407 is accurately embedded in the first connecting port 8, thereby achieving a firm connection. At the same time, during the clamping process, the fixed block 1407 will apply pressure to the sealing ring 13 and the sealing ring 11 that have been preset at the second connecting port 9. The sealing ring 13 and the sealing ring 11 are made of rubber. When the sealing ring 13 and the sealing ring 11 are deformed and fill the gap after being compressed, they ensure the tight sealing of the pipeline connection, thereby completing the tightening and sealing work of the entire pipeline connection. When the inside of the pipeline is in use, the insulation layer 7 will maintain the heat, thereby causing the sealing ring 13 and the sealing ring 11 to expand due to heat, which is conducive to the sealing ring 13 and the sealing ring 11 to better fill and adapt to the tiny gap at the connection, further strengthening the sealing effect, ensuring that the pipeline can maintain excellent sealing performance even under high-temperature working conditions, preventing medium leakage, and also avoiding the intrusion of the external environment into the inside of the pipeline, ensuring the safe and stable operation of the pipeline system.

[0038] A plurality of circular grooves 10 are provided on the outside of the first connection port 8 and the second connection port 9, a protective ring 2 is slidably provided on the outside of the second connection port 9, and a plurality of limiting balls 12 are fixedly provided inside the protective ring 2. When the first connection port 8 and the second connection port 9 are successfully docked, the protective ring 2 located on the outside of the second connection port 9 is pushed. When the protective ring 2 slides to a preset locking position, the plurality of limiting balls 12 fixed inside the protective ring 2 will be accurately embedded in the corresponding circular grooves 10 provided on the outside of the first connection port 8 and the second connection port 9, forming a firm connection, which not only enhances the stability between the connection ports, but also increases the torsion resistance and safety of the overall structure of the pipeline, effectively prevents loosening of the connection due to thermal expansion and contraction, and further ensures the airtightness and long-term efficient operation of the pipeline.

[0039] Working principle: when the first connection port 8 and the second connection port 9 are connected, the thrust of the second connection port 9 will act on the connection block 1401, causing the connection block 1401 to move downward, and squeeze the compression spring 1402 connected thereto to make it contract. At the same time, inside the first connection port 8, the pre-arranged limit block 1404 will also be squeezed accordingly, thereby causing the spring 1403 connected thereto to contract. When the connection port is docked to the set position, the spring 1403 begins to act on the limit block 1404 in the opposite direction due to its own elastic restoring force, driving the limit block 1404 to apply pressure to the trapezoidal block 1405 at the output end of the first cylinder 1406, and causing the first cylinder 1406 inside the first connection port 8 to contract, resulting in the transfer of its internal airflow to the second connection port 9 The internal second cylinder 1408 causes the fixed block 1407 at the output end of the second cylinder 1408 to expand and contract. As the fixed block 1407 expands, it is eventually embedded in the first connecting port 8, thereby stabilizing the connection between the pipes. At the same time, the sealing ring 13 and the sealing ring 11 installed in the second connecting port 9 are squeezed when combined with the first connecting port 8 to achieve a tight fit and a sealed and fixed effect. In addition, the first pipe 1 and the second pipe 3 are provided with an outer protective layer 4, which can reduce the damage to the pipe by the external environment. The corrosion-resistant layer 5 can enhance the resistance of the pipe to various corrosive environments. The inner protective layer 6 provides a protective barrier for the medium transported inside the pipe, and the thermal insulation layer 7 can maintain the constant temperature inside the pipe and effectively prevent heat loss.
