Description

Technical Field

[0001] The embodiments of this application relate to the field of pipeline compensation device technology, specifically to a position compensation component and protection detection device suitable for pipelines. Background Technology

[0002] The statements herein are provided merely as background information in connection with this application and do not necessarily constitute prior art.

[0003] The floor area of ​​the nuclear island plant is one of the important factors affecting the overall economics of large sodium-cooled fast reactors. The piping of sodium-cooled fast reactors is usually arranged in the form of π bends to absorb the thermal displacement caused by the piping and equipment inside the sodium-cooled fast reactor.

[0004] However, this method of arranging pipes in a π-bend configuration still has many shortcomings. Summary of the Invention

[0005] A brief overview of this application is provided below to offer a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the application. It is not intended to identify key or essential parts of the application, nor is it intended to limit its scope. Its purpose is merely to present certain concepts in a simplified form as a prelude to the more detailed description that follows.

[0006] In a first aspect, embodiments of this application provide a position compensation component suitable for pipelines, comprising: a connector configured to communicate with a pipeline; a position compensation component connected to the pipeline via the connector and configured to compensate for at least one type of displacement generated by the pipeline when the position of the pipeline changes; and a protective component configured to protect the position compensation component and prevent liquid media in the pipeline from damaging the position compensation component.

[0007] The position compensation component provided in the embodiments of this application can compensate for at least one type of displacement generated in the pipeline, thereby improving the pipeline's ability to absorb displacement. Furthermore, the position compensation component is protected by a protective component, which can prevent the liquid medium in the pipeline from damaging the position compensation component and extend its service life. Compared with the pipeline arrangement using a π-bend method in related technologies, using the position compensation component provided in this application to compensate for pipeline displacement is also beneficial to reducing the stress on the pipeline and the length of the pipeline, thereby helping to reduce the area of ​​the reactor building.

[0008] Secondly, embodiments of this application also provide a protection and detection device suitable for pipelines, comprising: a position compensation component, a heating protection component, and a detection component according to embodiments of this application, wherein the position compensation component is disposed on the pipeline and configured to compensate for at least one type of displacement generated by the pipeline; the heating protection component is configured to protect the position compensation component so that the position compensation component can absorb the displacement of the pipeline and is configured to heat and insulate the position compensation component; the detection component is disposed on the heating protection component and configured to detect leakage of liquid medium in the position compensation component.

[0009] The protection and detection device provided in the embodiments of this application integrates the functions of compensating for displacement generated by the pipeline, detecting leakage of liquid medium in the pipeline, and heating and insulating the pipeline. It can use a position compensation component to compensate for at least one type of displacement generated by the pipeline, thereby improving the pipeline's ability to absorb displacement. Then, a heating protection component is used to protect the position compensation component to extend its service life. At the same time, it can also heat and insulate the position compensation component to ensure that it is preheated to a temperature that prevents the liquid medium from solidifying before filling the pipeline with liquid medium. This avoids the situation where the liquid medium solidifies at the position compensation component due to its low temperature when the liquid medium is filled into the pipeline. Finally, a detection component is used to detect leakage of liquid medium in the position compensation component, so as to detect the leakage of liquid medium in the position compensation component in a timely manner and facilitate maintenance.

[0016] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0017] It should be noted that, unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning as understood by a person with ordinary skills in the field to which this application pertains.

[0018] In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] In related technologies, the liquid medium inside the main loop pipes of sodium-cooled fast reactors is liquid sodium. Since the operating temperature of liquid sodium is relatively high, the thermal displacement of the pipes is also relatively large. If the pipes are arranged in the form of π bends, the stress level of the pipes will be relatively high, and the total length of the pipes will also be relatively long, which will increase the footprint of the nuclear island plant and make the equipment arrangement more crowded.

[0020] To address the aforementioned technical problems, embodiments of this application provide a position compensation component suitable for pipelines. Figure 1 A schematic diagram of a position compensation assembly for a pipeline according to an embodiment of this application is shown, as follows: Figure 1 As shown, the position compensation component 100 may include at least a connector 11, a position compensation component 12, and a protective component 13.

[0021] In some embodiments, the connector 11 is configured to communicate with the pipeline; the position compensation member 12 is connected to the pipeline through the connector 11 and is configured to compensate for at least one type of displacement of the pipeline when the position of the pipeline changes; the protective member 13 is configured to protect the position compensation member 12 and prevent the liquid medium in the pipeline from damaging the position compensation member 12.

[0022] The position compensation component 100 provided in the embodiments of this application can compensate for at least one type of displacement generated by the pipeline, thereby improving the pipeline's ability to absorb displacement. Furthermore, the position compensation component 12 is protected by the protective component 13, which can prevent the liquid medium in the pipeline from damaging the position compensation component 12 and extend the service life of the position compensation component 12. Compared with the pipeline arrangement using the π-bend method in related technologies, the position compensation component 100 provided in this application can compensate for the displacement of the pipeline, which is also beneficial to reduce the stress on the pipeline and the length of the pipeline, thereby helping to reduce the area of ​​the reactor building.

[0023] In some embodiments, the pipeline can be a pipeline arranged within the nuclear island building, such as the main loop pipeline of a sodium-cooled fast reactor, to compensate for thermal displacement caused by the pipeline.

[0024] In some embodiments, the type of displacement generated by the pipeline may include, but is not limited to, axial displacement and angular displacement.

[0025] In some embodiments, Figure 2 A schematic diagram of a position compensation assembly for a pipeline according to another embodiment of this application is shown. Figure 3 A schematic diagram of a position compensation assembly for a pipeline according to yet another embodiment of this application is shown, as follows: Figure 2 and Figure 3As shown, the position compensation component 12 includes a compensation component 121 and a limiting component 122. The compensation component 121 and the limiting component 122 are respectively connected to the pipeline through the connector 11. The limiting component 122 is configured to limit the compensation component 121 when the pipeline arrangement angle changes, so that the compensation component 121 can compensate for the angular displacement generated by the pipeline. The protective component 13 is configured to protect the compensation component 121.

[0026] The position compensation component 100 provided in the embodiments of this application is connected to the pipeline by a compensation component 121 and a limiting component 122 respectively. In this way, the position of the compensation component 121 can be restricted by the limiting component 122, so that the compensation component 121 can rotate under the restriction of the limiting component 122, thereby compensating for the angular displacement generated by the pipeline. This is applicable to the position compensation needs of pipelines arranged in different ways and pipelines with different displacement amounts, thereby ensuring the safe operation of the pipeline.

[0027] In some embodiments, such as Figure 1 As shown, the connector 11 includes a first connecting part 111 and a second connecting part 112, and the position compensation member 12 is connected to the first connecting part 111 and the second connecting part 112 respectively; the first connecting part 111 and the second connecting part 112 are also configured to be connected to different pipes respectively.

[0028] The position compensation component 100 provided in the embodiments of this application uses a first connecting part 111 and a second connecting part 112 to connect different pipes respectively, so as to achieve the purpose of setting the position compensation component 100 between two pipes, thereby compensating for the displacement of the pipes.

[0029] In some embodiments, the first connecting part 111 and the second connecting part 112 may be, for example, pipe segments. Those skilled in the art can determine the dimensions of the first connecting part 111 and the second connecting part 112 based on the dimensions of the pipe to be connected, and this application does not impose any limitations on this.

[0030] In some embodiments, such as Figure 2 and Figure 3 As shown, the compensation member 121 is positioned between the first connecting portion 111 and the second connecting portion 112 of the connector 11 to compensate for the angular displacement generated by the pipeline, thereby improving the pipeline's ability to absorb angular displacement.

[0031] In some embodiments, the compensation member 121 may be, for example, a bellows. In such embodiments, the two ends of the bellows may be welded to the first connecting portion 111 and the second connecting portion 112 respectively to compensate for the angular displacement generated by the pipeline.

[0032] In some embodiments, the position compensation member 12 may consist of only the position compensation member 12; in other words, the position compensation member 12 is a compensation member used to compensate for displacement generated in the pipeline. In such an embodiment, the position compensation member 12 is disposed between the first connecting portion 111 and the second connecting portion 112 of the connector 11 to compensate for axial displacement generated in the pipeline, thereby improving the pipeline's ability to absorb axial displacement.

[0033] In some embodiments, the protective member 13 is disposed inside the first connecting portion 111 and / or the second connecting portion 112, and is configured to guide the liquid medium within the first connecting portion 111 and / or the second connecting portion 112.

[0034] The position compensation component 100 provided in the embodiments of this application has the protective member 13 configured to guide the liquid medium in the first connecting part 111 and / or the second connecting part 112. This can prevent the liquid medium flowing through the first connecting part 111 and / or the second connecting part 112 from impacting the position compensation component 12, thereby preventing damage to the position compensation component 12.

[0035] In some embodiments, the protective member 13 may be a flow guide tube, which facilitates connection with the first connecting part 111 and / or the second connecting part 112 while achieving the flow guiding function.

[0036] In some embodiments, the limiting member 122 includes a plurality of limiting connecting portions 1221, a first limiting portion 1222, and a second limiting portion 1223. The first limiting portion 1222 and the second limiting portion 1223 are respectively connected to the connecting member 11 through a limiting connecting portion 1221. The first limiting portion 1222 and the second limiting portion 1223 are configured to rotate with the pipeline when the arrangement angle of the pipeline changes.

[0037] The position compensation component 100 provided in the embodiments of this application configures the first limiting part 1222 and the second limiting part 1223 to rotate with the pipeline when the pipeline arrangement angle changes. This allows the pipeline to generate angular displacement and limits the axial displacement change of the compensation component 121, thereby enabling the compensation component 121 to compensate for the angular displacement of the pipeline and improve the pipeline's ability to absorb angular displacement.

[0038] In some embodiments, there are multiple first limiting parts 1222, and the multiple first limiting parts 1222 and second limiting parts 1223 are configured to be rotatably connected along the same plane, so as to compensate for the angular displacement of the pipeline along the same plane.

[0039] In some embodiments, such as Figure 2As shown, the first ends of multiple first limiting parts 1222 are connected to a limiting connecting part 1221, the first end of the second limiting part 1223 is connected to another limiting connecting part 1221, and the second ends of multiple first limiting parts 1222 are connected to the second ends of the second limiting part 1223. The second end of the second limiting part 1223 is disposed between the second ends of multiple first limiting parts 1222. This ensures that the first limiting parts 1222 and the second limiting parts 1223 can rotate along the same plane while achieving a stable connection.

[0040] In some embodiments, there are multiple first limiting parts 1222, and the multiple first limiting parts 1222 and second limiting parts 1223 are configured to be rotatably connected along multiple planes. This allows the compensation member 121 to rotate along multiple planes, thereby achieving the purpose of compensating for the angular displacement of the pipeline along multiple planes using the compensation member 121.

[0041] In some embodiments, such as Figure 3 As shown, there are also multiple second limiting portions 1223. The first ends of multiple first limiting portions 1222 are connected to a limiting connecting portion 1221, and the second ends of multiple first limiting portions 1222 are also connected to multiple second limiting portions 1223. Multiple second limiting portions 1223 are also connected to another limiting connecting portion 1221. In this embodiment, one second limiting portion 1223 is configured to rotate along a first plane, and another second limiting portion 1223 is configured to rotate along a second plane. The first plane is perpendicular to the second plane, thus enabling multiple first limiting portions 1222 and second limiting portions 1223 to be rotatably connected along multiple planes.

[0042] In some embodiments, the first plane may be, for example, a direction parallel to the axial direction of the pipe.

[0043] In some embodiments, such as Figures 1 to 3 As shown, there are multiple position compensation components 12, which are arranged opposite to each other on the pipeline to further improve the pipeline's ability to absorb displacement.

[0044] Embodiments of this application also provide a protection and detection device suitable for pipelines. Figure 4 A schematic diagram of a protection and detection device for pipelines according to an embodiment of this application is shown, as follows: Figure 4As shown, the protection and detection device includes: a position compensation component 100, a heating protection component 200, and a detection component 300 according to embodiments of this application. In some embodiments, the position compensation component 100 is disposed on the pipeline and configured to compensate for at least one type of displacement generated in the pipeline; the heating protection component 200 is configured to protect the position compensation component 100 so that the position compensation component 100 can absorb the displacement of the pipeline and is configured to heat and keep the position compensation component 100 warm; the detection component 300 is disposed on the heating protection component 200 and configured to detect leakage of liquid medium in the position compensation component 100.

[0045] The protection and detection device provided in the embodiments of this application integrates the functions of compensating for pipeline displacement, detecting leakage of liquid medium in the pipeline, and heating and insulating the pipeline. It can use the position compensation component 100 to compensate for at least one type of displacement in the pipeline, thereby improving the pipeline's ability to absorb displacement. Then, the heating protection component 200 is used to protect the position compensation component 100 to extend its service life. At the same time, it can also heat and insulate the position compensation component 100 to ensure that it is preheated to a temperature that prevents the liquid medium from solidifying before filling the pipeline with liquid medium. This avoids the situation where the liquid medium solidifies at the position compensation component 100 due to its low temperature when filling the pipeline with liquid medium. Finally, the detection component 300 is used to detect leakage of liquid medium in the position compensation component 100, so as to detect the leakage of liquid medium in the position compensation component 100 in a timely manner and facilitate maintenance.

[0046] In some embodiments, such as Figure 4 As shown, the heating protection assembly 200 may include a heating element, a protective body 21, and an insulation element 22. The protective body 21 is disposed between the position compensation assembly 100 and the insulation element 22, and is configured to have a predetermined gap with the position compensation assembly 100 to ensure that the position compensation assembly 100 can absorb the displacement generated by the pipeline. The heating element may be disposed on the position compensation assembly 100 and / or the protective body 21, and this application does not limit this. The insulation element 22 may be disposed outside the protective body 21 and cover the protective body 21 to improve the insulation effect on the position compensation assembly 100.

[0047] In some embodiments where a protective body 21 is provided outside the position compensation component 100, those skilled in the art can know the value of the predetermined gap between the protective body 21 and the position compensation component 100, and this application does not limit this.

[0048] In some embodiments, the heating power of the heating element and the size of the insulation element 22 can be determined according to the heating rate and insulation requirements of the position compensation component 100 by the protection detection device.

[0049] In some embodiments, the detection component 300 may be positioned below the lowest point of the position compensation component 100, and its detection range may cover the entire arrangement range of the position compensation component on the pipeline, so as to ensure the reliability of the detection results obtained by the detection component 300.

[0050] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0051] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
