Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a flange structure and a pipeline component. Background Art

[0002] A flange is a component used to connect shafts and pipe ends. The flange has several mounting holes, into which the pipe is inserted. The connection is then achieved through welding or other fasteners. The flange has holes for bolts and is typically a disk-shaped metal body with several holes cut around the perimeter for attachment.

[0003] Brazing is a welding method in which a filler metal (a material with a melting point lower than the melting point of the workpiece) and the workpiece are simultaneously heated to the melting point of the filler metal, where the liquid filler metal fills the gap between the solid workpieces to form a joint. This method is commonly used to weld flanges and pipes. However, when manually brazing flanges and pipes, it is impossible to ensure that the flange remains horizontal, making the flow of the filler metal difficult to control. During the welding process, the filler metal often flows into the holes used to insert bolts, affecting the assembly of the flange structure.

[0004] Therefore, there is an urgent need for a flange structure and a pipeline assembly to solve the above problems. Utility Model Content

[0005] One purpose of the utility model is to provide a flange structure that can limit the flow direction of solder and prevent the solder from flowing into the connecting hole to affect the assembly of the flange structure.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] A flange structure is provided, comprising:

[0008] A main body, wherein the main body is provided with a first connecting hole and a second connecting hole, the first connecting hole is used to connect a pipeline to be fixed, and the second connecting hole is used to fix the flange structure;

[0009] A stopper is connected to the main body and protrudes from a side of the main body connected to the pipeline. The stopper is an annular protrusion and is arranged around the second connecting hole.

[0010] As an optional solution for the flange structure, a plurality of the second connecting holes and the stopper are provided, and each of the second connecting holes is correspondingly provided with the stopper.

[0011] As an optional solution to the flange structure, a step structure is provided on the inner wall surface of the stop portion.

[0012] As an optional solution of the flange structure, the flange structure further includes a protrusion, which protrudes radially from the outer wall of the stop portion.

[0013] As an optional solution to the flange structure, the protrusion is arranged around the stop portion.

[0014] As an optional solution to the flange structure, a guide groove is provided on the surface of the main body connected to the pipeline.

[0015] As an optional solution of the flange structure, the flange structure further includes an extension portion, which is protruded from a side of the main body away from the pipeline, and the extension portion forms a through hole, which is connected to the first connecting hole.

[0016] As an optional solution for the flange structure, the first connecting hole includes a first hole segment and a second hole segment, the aperture of the first hole segment is larger than the aperture of the second hole segment, an abutment surface is formed between the first hole segment and the second hole segment, and the pipeline abuts against the abutment surface.

[0017] Another object of the present invention is to provide a pipeline assembly that can ensure the neatness of the connecting holes of the flange structure and achieve normal assembly of the flange structure.

[0018] To achieve this purpose, the present invention adopts the following technical solutions:

[0019] Provided is a pipeline assembly, comprising a pipeline and the above-mentioned flange structure, wherein the pipeline is passed through the first connecting hole, and the side wall of the pipeline is welded to the main body.

[0020] As an optional solution of the pipeline assembly, the pipeline assembly further includes a connecting piece, and the connecting piece is passed through the second connecting hole.

[0021] Beneficial effects of the utility model:

[0022] The utility model provides a flange structure, in which a stopper is provided on one side of a main body connected to a pipeline, and the stopper is provided around a second connection hole. When the main body and the pipeline are welded, the solder can be guided to flow along the outer wall of the stopper, preventing the solder from flowing directly into the second connection hole. During the welding process, in order to facilitate welding, the position and tilt angle of the main body need to be constantly adjusted, and the solder will also flow upward along the outer wall of the stopper. At this time, the solder needs to overcome gravity to flow, thereby reducing the flow rate of the solder. In addition, the solder needs to flow through the outer wall, top surface and inner wall of the stopper before it can flow into the second connection hole, which can increase the distance the solder flows into the second connection hole, further preventing the solder from flowing into the second connection hole, ensuring the cleanliness of the second connection hole, and thus ensuring the normal assembly of the flange structure.

[0023] The utility model also provides a pipeline assembly, the pipeline is passed through the first connecting hole and is welded to the main body, and the flange structure can prevent solder from entering the second connecting hole, thereby ensuring the connection quality of the product.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0032] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation.

[0035] like Figures 1 to 3 As shown, the flange structure of this embodiment includes a main body 100 and a stopper 200. The main body 100 is a disc-shaped structure, with a first connection hole 110 and a second connection hole 120 extending therethrough. The first connection hole 110 is used to connect a pipeline to be fixed, and the second connection hole 120 is used to fix the flange structure. The stopper 200 is connected to the main body 100 and protrudes from the side of the main body 100 connected to the pipeline. The stopper 200 is an annular protrusion and is arranged around the second connection hole 120.

[0036] Based on the above design, a stopper 200 is provided on the side of the main body 100 connected to the pipeline. The stopper 200 is provided around the second connection hole 120. When the main body 100 and the pipeline are welded, the solder can be guided to flow along the outer wall of the stopper 200, preventing the solder from directly flowing into the second connection hole 120. During the welding process, in order to facilitate welding, the position and tilt angle of the main body 100 need to be constantly adjusted, and the solder will also flow upward along the outer wall of the stopper 200. At this time, the solder needs to overcome gravity to flow, thereby reducing the flow rate of the solder. In addition, the solder needs to flow through the outer wall, top surface and inner wall of the stopper 200 before it can flow into the second connection hole 120. This can increase the distance the solder flows into the second connection hole 120, further prevent the solder from flowing into the second connection hole 120, ensure the cleanliness of the second connection hole 120, and further ensure the normal assembly of the flange structure, thereby improving the product qualification rate.

[0037] It should be noted that in actual use, to ensure the connection strength and sealing of the flange structure, the main body 100 is provided with multiple second connection holes 120. In this case, multiple stoppers 200 are also provided, and each second connection hole 120 is provided with a corresponding stopper 200, thereby ensuring cleanliness within all second connection holes 120. In this embodiment, two second connection holes 120 are provided, and the two second connection holes 120 are symmetrically arranged on the main body 100. In some other embodiments, three, four, six, etc. second connection holes 120 can also be provided, with multiple second connection holes 120 evenly distributed around the edge of the main body 100, achieving a stable connection between the flange structure and other objects.

[0038] Optionally, a guide groove is provided on the surface of the main body 100 connected to the pipeline. When welding the pipeline and the main body 100, the solder flows on the surface of the main body 100 and can preferentially enter and flow along the guide groove, thereby restricting the flow direction of the solder and reducing the flow of solder toward the second connection hole 120. In addition, some solder can be retained in the guide groove, reducing the volume of solder that can flow freely, thereby reducing the accumulation of solder outside the stopper 200 and reducing the risk of solder flowing over the stopper 200 and entering the second connection hole 120. For example, the guide groove can be configured as a linear groove structure, or a spiral groove structure, or a plurality of concentric circular groove structures, etc.

[0039] Optionally, the flange structure may further include a protrusion that radially protrudes from the outer wall of the stopper 200. When the solder flows upward along the outer wall of the stopper 200, the protrusion can increase the solder flow path, reduce the solder flow rate, and prevent further solder flow. The protrusion can be provided at the end of the stopper 200 close to the main body 100, or at the middle of the stopper 200 or at the end away from the main body 100.

[0040] Preferably, the protrusion is disposed around the stopper 200, increasing the circumferential length of the protrusion on the stopper 200 so that the protrusion can block the flow of solder at all circumferential positions of the stopper 200. Optionally, the cross-section of the protrusion can be triangular, semicircular, rectangular, or trapezoidal.

[0041] Furthermore, a step structure 210 is provided on the inner wall of the stop portion 200, so that the inner wall of the stop portion 200 forms a first inner wall surface 211, a step surface 212 and a second inner wall surface 213, and the first inner wall surface 211 is located above the second inner wall surface 213, that is, when the solder flows from the top surface of the stop portion 200 into the interior of the stop portion 200, it flows through the first inner wall surface 211, the step surface 212 and the second inner wall surface 213 in sequence, and finally flows into the second connecting hole 120.

[0042] By providing the step structure 210, the solder needs to change its flow direction multiple times when flowing on the inner wall of the stopper 200. Each time the flow direction changes, the flow speed of the solder needs to be accelerated from zero, thereby reducing the overall flow speed of the solder on the inner wall of the stopper 200, further preventing the solder from flowing smoothly into the second connection hole 120, and ensuring the cleanliness of the second connection hole 120. In this embodiment, only one step structure 210 is provided on the stopper 200. In some other embodiments, the stopper 200 may also be provided with multiple step structures 210, such as two or three. The number of stoppers 200 can be adjusted according to the height of the stopper 200.

[0043] This embodiment also provides a pipeline assembly, including a pipeline and the aforementioned flange structure. The pipeline is inserted into the first connection hole 110, and the sidewall is welded to the main body 100. When welding the pipeline and the flange structure, the flange structure prevents solder from entering the second connection hole 120, ensuring cleanliness within the second connection hole 120 and facilitating product connection quality.

[0044] Furthermore, the first connecting hole 110 includes a first hole section 111 and a second hole section 112. The aperture of the first hole section 111 is larger than the aperture of the second hole section 112. A contact surface 113 is formed between the first hole section 111 and the second hole section 112. One end of the pipeline is arranged in the first hole section 111 and abuts against the abutment surface 113, which is conducive to the positioning of the pipeline, so that the stability between the pipeline and the main body 100 can be ensured when welding the pipeline.

[0045] Furthermore, the flange structure includes an extension portion 300, which protrudes from the side of the main body 100 facing away from the pipeline. The extension portion 300 forms a through hole 310, which is connected to the first connection hole 110. By using the through hole 310, the first connection hole 110 can be extended, facilitating the connection between the first connection hole 110 and the external pipeline. Specifically, the through hole 310 is also provided with a flared portion 311, which is located at the end of the through hole 310 away from the first connection hole 110, facilitating the passage of other pipelines into the through hole 310. In this embodiment, the flared portion 311 is a tapered hole structure, which is simple in structure and easy to manufacture.

[0046] Furthermore, the pipeline assembly further includes a connector, which is provided in the second connection hole 120. For example, the second connection hole 120 is configured as a threaded hole, and the connector is configured as a bolt, which can be threadedly connected to the threaded hole, resulting in a simple structure and low cost.

[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
