For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] Pipelines are an especially important part of the pipeline system and are widely used in various industries such as petroleum, metallurgy, water supply and drainage, slurry, chemical industry, and medicine. The main function of pipelines is to transport media such as gas, liquid, and solid-liquid mixtures.

[0035] At present, flange connection is usually used for pipeline connection (such as the connection between the pump outlet pipe flange and the on-site pipeline flange). The distance between the flange end face of the pipeline installation device and the flange end face of the chemical on-site pipeline determines whether the pipeline device can be successfully installed.

[0036] However, at the construction site, the distance between the end face of the pipeline installation flange and the end face of the chemical site pipeline flange is often too large or too small due to on-site pipeline changes, data errors, part processing errors or installation tolerances, which makes it impossible to install the pipeline smoothly.

[0037] In order to solve the problem that one pipe cannot be smoothly connected to another pipe in the current pipe connection process, an embodiment of the present application provides a pipe with adjustable length. The solution provided by the embodiment of the present application will be described in detail below in conjunction with the drawings in the specification.

[0038] Figure 1 This is a schematic diagram of the overall structure of a pipe with adjustable length provided in one embodiment of the present application; Figure 2 yes Figure 1 A cross-sectional view of the pipe in FIG. Figure 3 yes Figure 1 A schematic structural diagram of the first pipe portion 100 of the middle pipe; Figure 4 yes Figure 1 Schematic diagram of the structure of the first pipe 210.

[0039] Reference Figures 1 to 4 As shown, the embodiment of the present application provides a length-adjustable pipeline, including a first pipe portion 100 and a second pipe portion 200. The first pipe portion 100 and the second pipe portion 200 are detachably fixedly connected together to adjust to a suitable total length according to the needs of the site to complete the connection with another pipeline.

[0040] Specifically, the first tube part 100 includes a tube body 110 and a connecting part 120, and the connecting part 120 is fixedly connected to the tube body 110 along the circumference of the tube body 110. The connecting part 120 can be a convex part or a concave part, that is, a boss or a groove, and is arranged entirely or partially along the circumference of the tube body 110. If the connecting part 120 is a boss, it can be integrally formed with the tube body 110, or fixed to the tube body 110 by welding or bolting. If the connecting part 120 is a groove, a groove of a target size can be machined on the tube body 110 using machining equipment.

[0041] The second pipe part 200 includes a first pipe fitting 210 and a second pipe fitting 220, which are buckled and connected together to form a pipeline channel 700. Exemplarily, the first pipe fitting 210 and the second pipe fitting 220 can be detachably fixed together using a connecting piece. And the diameter of the pipeline channel 700 is greater than or equal to the outer diameter of the pipe body 110, so that the pipe body 110 can be placed in the pipeline channel 700.

[0042] In addition, at least one of the first pipe fitting 210 and the second pipe fitting 220 is provided with a plurality of mating parts 230, and the plurality of mating parts 230 are arranged at intervals along the extension direction of the pipeline channel 700, and the mating parts 230 are meshed and connected with the connecting part 120. The connecting part 120 can select the connection position with the mating part 230, and adjust the overall length of the first pipe part 100 and the second pipe part 200 after being connected, so as to facilitate the adjustment of the total length of the two to a suitable length at the pipeline connection construction site, and complete the connection with another pipeline. It can ensure that the distance between the flange end face of the pipeline device and the flange end face of the pipeline on the chemical site meets the installation requirements when the pipeline is installed, so as to facilitate installation or disassembly, avoid replacing the pipeline, reduce the cost of pipeline replacement, and improve installation efficiency.

[0043] Continue to refer to Figures 1 to 3 As shown, in some examples, there are multiple connecting parts 120, and the multiple connecting parts 120 are arranged at a first distance along the extension direction of the pipe body 110; and the multiple matching parts 230 are arranged at a first distance along the extension direction of the pipeline channel 700, so that each connecting part 120 and each matching part 230 can be matched together, thereby making the pipe body 110 firmly connected with the first pipe member 210 and the second pipe member 220. Exemplarily, the connecting part 120 is configured as one of a concave part and a convex part, and the matching part 230 is configured as the other of the concave part and the convex part; the concave part and the convex part are matched and connected.

[0044] Reference Figure 2 As shown, in one embodiment of the present application, the connecting portion 120 is configured as a convex portion, which may be a boss, and a plurality of bosses are evenly arranged at a first distance along the extension direction of the tube body 110, and the matching portion 230 is configured as a concave portion, which may be a groove, and a plurality of grooves are arranged at a first distance along the extension direction of the pipeline channel 700. The first distance can be adjusted accordingly according to actual needs and is not limited here. In addition, it should be noted that the extension direction of the tube body 110 and the extension direction of the pipeline channel 700 can refer to Figure 2 The x direction is shown in .

[0045] In some examples, the cross-sections of the connecting portion 120 and the matching portion 230 are configured as rectangles or triangles to facilitate the matching between the connecting portion 120 and the matching portion 230 and to ensure that the two are tightly matched and connected.

[0046] In some examples, in order to ensure the effect of the snap-fit ​​connection between the first pipe 210 and the second pipe 220, the pipeline further includes a first connection assembly 300 and a second connection assembly 400. One side of the first pipe 210 and one side of the second pipe 220 are connected through the first connection assembly 300, and the other side of the first pipe 210 and the other side of the second pipe 220 are connected through the second connection assembly 400.

[0047] At least one of the first connection assembly 300 and the second connection assembly 400 is configured as a bolt fastening assembly. For example, the first connection assembly 300 can be configured as a pin connection assembly, and the second connection assembly 400 can be configured as a bolt fastening assembly. The first connection assembly 300 and the second connection assembly 400 are both configured as bolt fastening assemblies. When the first connection assembly 300 can be configured as a pin connection assembly, and the second connection assembly 400 is configured as a bolt fastening assembly, one side of the first pipe 210 is rotatably connected to one side of the second pipe 220 through a pin, that is, the first pipe 210 can be opened and closed and rotated around the second pipe 220. The other side of the first pipe 210 is fixedly connected to the second pipe 220 by bolts.

[0048] It is understandable that when the second pipe part 200 is blocked, the first pipe 210 and the second pipe 220 can be unfolded to facilitate the rapid removal of foreign matter. At the same time, since the first pipe 210 and the second pipe 220 of the pipeline are unfolded, it is convenient to evenly spray the inner walls of the first pipe 210 and the second pipe 220 with protective materials such as anti-corrosion paint, thereby improving the anti-corrosion performance and extending the service life.

[0049] In addition, continue to refer to Figures 1 to 3 As shown, the pipe body 110 is also provided with a sensor installation hole 111, and the sensor installation hole 111 is used to place a detection sensor. For example, the sensor installation hole 111 can be installed with corresponding vibration, temperature and other sensors, so as to realize pipeline vibration, temperature and other detection.

[0050] In order to improve the sealing performance of the pipeline, a sealing gasket 500, such as a PTFE gasket, is provided between the first pipe 210 and the second pipe 220; a sealing ring 600, such as an O-ring 600, is provided between the convex part and the concave part. The sealing gasket 500 and the sealing ring 600 are both made of rubber material, have elasticity, and can respectively fill the gap between the first pipe 210 and the second pipe 220 and between the convex part and the concave part to improve the sealing effect.

[0051] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0052] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
