Description

Technical Field

[0001] This utility model relates to steam heating pipes, specifically to a pipeline device. Background Technology

[0002] Condensation inevitably occurs during the main pipeline's transport process. To ensure the safe operation of the steam transmission system, this condensate must be drained promptly. Typically, the main pipeline design includes two types of condensate traps: start-up condensate traps and continuous condensate traps. Continuous condensate traps are equipped with automatic steam traps that automatically drain small amounts of condensate during normal pipeline operation. Start-up condensate traps are primarily used during the initial system startup phase; when the condensate volume is large, a manually opened valve allows for rapid drainage.

[0003] However, in practical applications, especially in frigid northern regions, the safety hazards of activating condensate traps cannot be ignored. Since the valves in these traps are typically manual valves welded to the pipes, they are prone to freezing and cracking under extremely cold conditions. Particularly when the pipe network is operating normally, the valves in the condensate traps are closed, and some stagnant condensate remains in the pipes above them. Because these valves are far from the main pipes, they cannot receive sufficient heat to prevent the condensate from freezing. Despite insulation measures, the valves may still freeze and crack under extreme low temperatures, potentially leading to serious safety accidents. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pipeline device with a heat preservation mechanism that can maintain the pipeline device at a suitable working temperature, prevent liquid from freezing and valve from cracking, and prevent other malfunctions caused by temperature changes, thus ensuring transportation safety.

[0005] This utility model provides a pipeline device, including a main pipeline, a connecting mechanism, a drainage pipe, and a heat insulation mechanism. The heat insulation mechanism includes a first heat insulation structure wrapped around the outer periphery of the main pipeline and a second heat insulation structure detachably connected to the first heat insulation structure. The connecting mechanism is connected through the first heat insulation structure and connects the main pipeline and the drainage pipe. The second heat insulation structure covers the outside of the drainage pipe and the connecting mechanism.

[0006] Preferably, the first insulation structure and the second insulation structure have channels formed on them for accommodating the connecting mechanism and the drainage pipe.

One end of the reducing connector is connected to the main pipe and the other end is connected to the pipe fitting. One end of the right-angle connector is connected to the pipe fitting and the other end is connected to the drainage pipe.

[0009] Preferably, the connection between the pipe fitting and the right-angle joint is flush with the outer surface of the first insulation structure.

[0010] Preferably, the first insulation structure includes at least one first heat insulation layer, at least one first insulation layer and a first metal layer connected sequentially from the side closest to the main pipe, and the second insulation structure includes at least one second insulation layer and a second metal layer connected sequentially from the side closest to the main pipe.

[0014] Preferably, the valve is a shut-off valve or a check valve.

[0015] The above technical solution provides a pipeline device, in which a first insulation structure and a second insulation structure detachably connected to the first insulation structure are provided on the outer periphery of the main pipeline.

[0025] This utility model provides a pipeline device, see [link]. Figure 1 and Figure 2 The system includes a main pipe 1, a connecting mechanism 3, a drain pipe 2, and an insulation mechanism 6. The insulation mechanism 6 includes a first insulation structure 61 wrapped around the main pipe 1 and a second insulation structure 62 detachably connected to the first insulation structure 61. The connecting mechanism 3 passes through the first insulation structure 61 and connects the main pipe 1 to the drain pipe 2. The second insulation structure 62 covers the drain pipe 2 and the connecting mechanism 3. The first insulation structure 61 and the second insulation structure 62 together constitute a complete insulation system, effectively reducing heat loss from the main pipe 1, its connecting mechanism 3, and the drain pipe 2. The second insulation structure 62 is detachably connected to the first insulation structure 61, allowing for easy disassembly of the second insulation structure 62 when maintenance or control of the drain pipe 2 or the connecting mechanism 3 is required. Without damaging the entire insulation mechanism 6, the second insulation structure 62 is installed outside the drain pipe 2 and the connecting mechanism 3, protecting the drain pipe 2 and the connecting mechanism 3 from the influence of the external environment, such as rainwater and dust. It can also prevent damage caused by accidental collisions. In the initial stage of pipeline network startup, liquid in the main pipeline 1 flows to the drain pipe 2 through the connecting mechanism 3. After disassembling the second insulation structure 62, the drain pipe 2 is opened to drain the liquid in the main pipeline 1. This condition usually lasts for several hours. When the main pipeline 1 is running normally, the drain pipe 2 is closed, and the second insulation structure 62 is fastened to provide integrated insulation for the drain pipe 2 and the main pipeline 1, so that the pipeline device maintains a suitable working temperature, avoids liquid freezing and valve cracking, and other malfunctions, which is conducive to ensuring the safe transportation of steam.

[0026] In some embodiments, the first insulation structure 61 and the second insulation structure 62 have channels 5 for accommodating the connecting mechanism 3 and the drain pipe 2. The connecting mechanism 3 and the drain pipe 2 are completely enclosed with the main pipe 1 through the channels 5, forming a relatively closed space. When the pipe is in normal operation, that is, when the drain pipe 2 is not working, the channels 5 can maintain a suitable temperature, ensuring that the steam pipe system can work normally when the external ambient temperature is low. At the same time, the heat emitted by the main pipe 1 flows or is stored in the channels 5, so that key components such as the electrically controlled valve 2-2 on the connecting mechanism 3 and the drain pipe 2 located in the channels 5 can operate normally.

[0027] In some embodiments, the gap between the connecting mechanism 3 and the drainage pipe 2 and the inner wall of the channel 5 is 20mm-70mm. Through reasonable gap design, the temperature inside the channel 5 is guaranteed, which helps to improve the stability of the pipeline system.

[0028] In some embodiments, the connecting mechanism 3 includes a reducing connector 3-1, a fitting 3-2, and a right-angle connector 3-3 connected in sequence. One end of the reducing connector 3-1 is connected to the main pipe 1, and the other end is connected to the fitting 3-2. One end of the right-angle connector 3-3 is connected to the fitting 3-2, and the other end is connected to the drain pipe 2. The reducing connector 3-1 is used to connect pipes of different diameters. The connection of one end of the reducing connector 3-1 to the main pipe 1 and the other end to the fitting 3-2 ensures that the main pipe 1 can be adapted to the size of the fitting 3-2, improving the sealing of the connection. This allows the connecting mechanism 3 to adjust the applicable size of the fitting 3-2 according to the required condensate flow rate of the main pipe 1. The right-angle connector 3-3 is used to change the direction of the fitting 3-2, which is beneficial for connecting the connecting mechanism 3 to the drain pipe 2. The connecting mechanism 3 consists of multiple components, which simplifies the construction process. The connecting mechanism 3 can be pre-assembled before construction and then used as a whole to connect the drain pipe 2, facilitating later maintenance and replacement.

[0029] In some embodiments, the connection between the pipe fitting 3-2 and the right-angle connector 3-3 is flush with the outer surface of the first insulation structure 61, which is beneficial for workers to remove the first insulation structure 61 and then operate the drainage pipe 2.

[0030] In some embodiments, the first insulation structure 61 includes at least one first insulation layer 61-1, at least one first insulation layer 61-2, and a first metal layer 61-3 connected sequentially from the side closest to the main pipe 1. The second insulation structure 62 includes at least one second insulation layer 62-2 and a second metal layer 62-3 connected sequentially from the side closest to the main pipe 1. The first insulation layer 61-1 is made of a material with low thermal conductivity, such as aluminum silicate or rock wool, which can reduce heat transfer from the main pipe 1. The first insulation layer 61-2 is made of a material with good insulation performance, such as polyurethane foam, perlite, or foamed cement, to maintain a suitable operating temperature between the main pipe 1 and the first insulation layer 61-1. A metal layer 61-3 is located on the outside to protect the structure of the first heat insulation layer 61-1 and the first thermal insulation layer 61-2 from external damage, such as rainwater, wind and sand. The second thermal insulation layer 62-2 is covered around the drainage pipe 2 and the connecting mechanism 3 to keep the drainage pipe 2 and the connecting mechanism 3 at a suitable operating temperature. The second metal layer 62-3 is located on the outside of the second thermal insulation layer 62-2, which is the side away from the main pipe 1. The first metal layer 61-3 and the second metal layer 62-3 respectively enhance the overall strength and quality of the first thermal insulation structure 61 and the second thermal insulation structure 62, which can withstand external impact and help extend the service life of the first thermal insulation structure 61 and the second thermal insulation structure 62.

[0031] In some embodiments, the second insulation structure 62 is connected to the first metal layer 61-3 via a magnetic layer 62-1. The magnetic layer 62-1 facilitates the connection or disassembly of the second insulation structure 62 and the first insulation structure 61 without the need for screws or other fasteners. The magnetic connection simplifies the installation process, improves the efficiency of disassembling the second insulation structure 62 to work on the drainage pipe 2, and reduces the labor intensity of workers. This also helps to reduce the cost and time of later maintenance of the drainage pipe 2 and the connecting mechanism 3. The magnetic layer 62-1 is closely attached to the first metal layer 61-3, which can improve the tightness of the connection between the second insulation structure 62 and the first insulation structure 61, and is conducive to improving the insulation effect of the second insulation structure 62 and the first insulation structure 61 on the drainage pipe 2 and the connecting mechanism 3.

[0032] In some embodiments, the first insulation layer 61-1 is an aluminosilicate needled blanket layer, the first insulation layer 61-2 and the second insulation layer 62-2 are glass wool layers, and the first metal layer 61-3 and the second metal layer 62-3 are steel plate layers and / or aluminum plate layers, respectively. The aluminosilicate needled blanket has a low thermal conductivity, which can reduce heat transfer in the main pipeline 1. The glass wool has good thermal insulation performance, which allows the second insulation layer 62-2 and the first insulation layer 61-2 to maintain a suitable operating temperature. The steel plate layer has high strength, wear resistance, and corrosion resistance, making it suitable as a protective layer. The aluminum plate layer is lightweight, corrosion-resistant, and has good reflective properties, and is used as the first metal layer 61-3 and the second metal layer 62-3 according to actual usage needs.

[0033] In some embodiments, at least two valves 4 are provided on the drainage pipe 2. The valves 4 are arranged at intervals along the length of the drainage pipe 2. Multiple valves 4 are arranged at intervals along the drainage pipe, which can realize the segmented isolation of the drainage pipe 2, so that the normal operation of other parts is not affected when the drainage pipe 2 is partially maintained.

[0034] In some embodiments, valve 4 is a shut-off valve or a check valve. The shut-off valve is mainly used to completely open or completely close the fluid passage and is suitable for applications that require full opening or full closing. When maintaining or isolating parts of the system, the shut-off valve can completely block the fluid flow to ensure safety. The check valve is used to prevent the fluid from flowing backward and ensure that the liquid can only flow in one direction. In the drain pipe 2, the check valve can prevent the condensate from flowing back, which helps to protect the equipment and pipes from damage.

[0035] To better understand the technical content of this utility model, the following description is based on the preferred technical features.

[0036] This utility model provides a pipeline device, including a main pipeline 1, a connecting mechanism 3, a drainage pipe 2, and an insulation mechanism 6. The insulation mechanism 6 includes a first insulation structure 61 wrapped around the outer periphery of the main pipeline 1 and a second insulation structure 62 detachably connected to the first insulation structure 61. The connecting mechanism 3 is connected to the first insulation structure 61 and connects the main pipeline 1 and the drainage pipe 2. The second insulation structure 62 covers the outside of the drainage pipe 2 and the connecting mechanism 3. The first insulation structure 61 and the second insulation structure 62 form a channel 5 for accommodating the connecting mechanism 3 and the drainage pipe 2. The gap between the connecting mechanism 3 and the drainage pipe 2 and the inner wall of the channel 5 is 20mm-70mm. The connecting mechanism 3 includes a reducing connector 3-1, a fitting 3-2, and a right-angle connector 3-3 connected in sequence. One end of the reducing connector 3-1 is connected to the main pipeline 1, and the other end is connected to the fitting 3-2.

[0037] The working process and beneficial effects of this pipeline device are as follows: In the initial stage of pipeline network startup, liquid in the main pipeline 1 flows to the drain pipe 2 through the connecting mechanism 3. After disassembling the second insulation structure 62, the liquid in the main pipeline 1 is discharged through the drain pipe 2 after opening each valve 4. This working condition generally lasts for several hours. When the main pipeline 1 is running normally, each valve 4 is closed, and the second insulation structure 62 is fastened to provide integrated insulation for the drain pipe 2 and the main pipeline 1, so that the pipeline device maintains a suitable working temperature, avoids liquid freezing and valve cracking, and other malfunctions, and ensures that the drain pipe 2 can work normally and the steam in the main pipeline 1 can be safely transported.
