[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figure 1 This diagram illustrates the connection between the first pipe section 11 and the second pipe section 12 of the delivery pipeline system according to an embodiment of the present invention. The delivery pipeline system provided in this embodiment includes an inlet and an outlet. The inlet is connected to a medium source (e.g., an air pump or an oil pump), and the outlet is connected to the medium inlet of a compressor. The delivery pipeline system delivers the driving medium (driving gas) output from the medium source to the compressor to drive its movement. The delivery pipeline system includes multiple prefabricated delivery pipe sections and an adjusting ring 20. Among the multiple delivery pipe sections, at least one prefabricated first pipe section 11 and a prefabricated second pipe section 12 connected to the first pipe section 11 are shown. A slip-on flange 112 is provided at the first end of section 11, and a butt-welded flange 122 for connecting to the slip-on flange 112 is provided at the first end of the second section 12 which is opposite to the first pipe section 11. An adjusting ring 20 is provided between the slip-on flange 112 of the first pipe section 11 and the butt-welded flange 122 of the second pipe section 12. The first end face of the adjusting ring 20 is in close contact with the sealing end face of the slip-on flange 112, and the second end face of the adjusting ring 20 is in close contact with the sealing end face of the butt-welded flange 122 which is opposite to the sealing end face of the slip-on flange.

[0023] In the pipeline system of this utility model, a loose flange 112 is provided on the first pipeline section 11, and a matching weld neck flange 122 is provided on the second pipeline section 12. The rotatable flange ring 1122 of the loose flange 112 ensures that the flange ring 1122 and the weld neck flange 122 can be well aligned and connected, thereby facilitating connection and improving installation efficiency and compatibility. An adjusting ring 20 is provided between the loose flange 112 and the weld neck flange 122. The adjusting ring 20 can accommodate the distance error between the sealing end face of the loose flange 112 and the sealing end face of the weld neck flange 122 during actual installation. This solves the problem in the prior art where, due to assembly and processing errors, the pipeline sections cannot be directly connected on-site according to the design, requiring on-site cutting and welding of the pipeline sections with heat to correct assembly and processing errors before the pipeline sections can be connected. By using structures such as the regulating ring 20 and the slip-on flange 112, it is ensured that the installation or maintenance of the pipeline system can be completed even using prefabricated pipeline sections without the need for on-site operations with open flames, thus improving adaptability to environments where open flames are strictly prohibited and increasing operational efficiency.

[0024] In some examples, for clarity of description, the prefabricated pipeline sections in the pipeline system can be divided into a first section 11, a second section 12, and a third section. As previously described, the first section 11 has a slip-on flange 112 at its first end, and a welding flange 122 or other connection structures at its second end; there are no restrictions on this. The second section 12 connects to the slip-on flange 112 of the first section 11. It also has a welding flange 122 at its first end, and a welding flange 122 or other connection structures at its second end; there are no restrictions on this. The remaining sections (i.e., those other than the first and second sections 11 and 12) can all be considered as the third section (not shown in the figure). It should be noted that the structure of the third section can be the same as or different from that of the second section 12; there are no restrictions on this.

[0025] In this embodiment, both ends of the third pipe segment are provided with welding flanges 122. Of course, in other embodiments, loose flanges or other pipeline structural components can also be used; there is no limitation on this. The first pipe segment 11, the second pipe segment 12, and the third pipe segment are all prefabricated pipe segments, and multiple third pipe segments are detachably connected by fasteners. Prefabricated pipe segments can be understood as pipe segments processed off-site and not requiring cutting or welding on-site. Fasteners include, but are not limited to, bolts, nuts, and rivets. Similarly, at least one third pipe segment is detachably connected to the second end of the second pipe segment 12 by fasteners. For example, the welding flange 122 of the third pipe segment and the welding flange 122 at the second end of the second pipe segment 12 are fastened together by bolts and nuts. And / or, at least one third pipe segment is detachably connected to the second end of the first pipe segment 11 by fasteners. For example, the welding flange 122 of the third pipe segment and the welding flange 122 at the second end of the first pipe segment 11 are fastened together by bolts and nuts.

[0026] Optionally, to accommodate processing and installation errors in pipelines extending in different directions, the first pipe segment 11 and the connected second pipe segment 12 constitute a pipe segment group, and the conveying pipeline system includes pipe segment groups arranged along at least two different directions. For example, the conveying pipeline system includes pipeline sections extending in three mutually perpendicular directions, denoted as the X direction, Y direction, and Z direction, respectively. The X and Y directions are mutually perpendicular, and the Z direction is perpendicular to the plane formed by the X and Y directions. The conveying pipeline system includes a first pipe segment 11 and a second pipe segment 12 extending along the X direction (the two constitute a pipe segment group), and an adjusting ring 20 is provided between them to absorb installation and processing errors in the X direction. The structure and principle of the Y and Z directions are similar, so they will not be described in detail.

[0027] like Figure 2 As shown, the loose flange 112 includes an installation section 1121 and a flange ring 1122. The installation section 1121 is welded to the first pipe section 11. The flange ring 1122 is fitted over the installation section 1121 and is rotatable relative to it. The flange ring 1122 has flange holes, and the welding flange 122 of the second pipe section 12 has corresponding flange holes. Thus, when connecting the loose flange 112 and the welding flange 122, the flange holes on the flange ring 1122 of the loose flange 112 can be rotated to align with the flange holes on the welding flange 122, facilitating the passage of fasteners and improving installation efficiency. For example, after the second pipe section 12 is installed, rotating the flange ring 1122 aligns the axis of the flange holes on the flange ring 1122 with the axis of the flange holes on the welding flange, thus facilitating the passage of fasteners.

[0028] Optionally, a sealing ring 1123 is provided at the end of the installation section 1121. The end face of the sealing ring 1123 can cooperate with the sealing end face of the loose flange 112 to clamp the adjusting ring and achieve end face sealing. Moreover, because the sealing ring 1123 protrudes outward, it can also limit the flange ring 1122.

[0029] Optionally, to ensure connection reliability, the inner diameter of the adjusting ring 20 is equal to the inner diameter of the first pipe section 11, and / or the outer diameter of the adjusting ring 20 is equal to the outer diameter of the sealing end face of the loose flange 112.

[0030] In this embodiment, the length of the adjusting ring 20 is equal to the first distance, which is the distance between the loose flange 112 and the weld neck flange 122 after the first pipe segment 11 and the second pipe segment 12 are assembled. This allows the adjusting ring 20 to absorb processing errors in each pipe segment and errors generated during installation, thus avoiding the need to modify the pipe segment structure on-site to ensure proper connection. For example, during installation, after all pipe segments except the first and second pipe segments 11 and 12 are connected according to the design, the first pipe segment 11 is connected to one of the third pipe segments, and the second pipe segment 12 is connected to another third pipe segment. Then, the distance between the sealing end face of the loose flange 112 of the first pipe segment 11 and the sealing end face of the corresponding weld neck flange 122 of the second pipe segment 12 can be measured as the first distance. An adjusting ring 20 of suitable length is then selected and installed between the first pipe segment 11 and the second pipe segment 12 to achieve pipe connection and sealing. Alternatively, if a suitable adjusting ring 20 is unavailable, it can be fabricated on-site before installation.

[0031] Optionally, such as Figure 3 and Figure 4 As shown, to ensure connection reliability and pipeline sealing, the first end face of the adjusting ring 20 includes at least one first reference position A. Figure 3 The dotted line in the figure represents the line connecting the first reference position A and the center of the adjusting ring 20. The second end face of the adjusting ring 20 includes a second reference position B corresponding to the first reference position A. The sealing end face of the loose flange 112 has a third reference position that fits with the first reference position A. The sealing end face of the welding flange 122 has a fourth reference position that fits with the second reference position B. The distance between the first reference position A and the second reference position B of the adjusting ring 20 is equal to the distance between the third reference position and the fourth reference position.

[0032] For example, the number of first reference positions A can be consistent with the number of flange holes on the slip-on flange 112. This ensures that the adjusting ring 20 can adapt to situations where the distance between different positions on the sealing end face of the slip-on flange 112 and the corresponding positions on the sealing end face of the weld neck flange 122 of the second pipe section 12 differs during installation, thereby ensuring a tight connection. By measuring the distances from multiple different positions on the sealing end face of the slip-on flange 112 to the corresponding positions on the sealing end face of the weld neck flange 122, the shape of the adjusting ring 20 can be made to better match the actual shape (especially the length) of the gap between the slip-on flange 112 and the weld neck flange 122, thereby improving the reliability of the seal.

[0033] In a specific example, when measuring the distance, the distance between the sealing end face of the slip flange 112 and the sealing end face of the weld neck flange 122 was measured in all directions at the flange hole positions. Then, the adjusting ring 20 was machined according to the measured dimensions. Finally, the adjusting ring 20 was clamped between the two sealing end faces to compensate for errors during pipeline manufacturing and installation. This is convenient and quick, and this operation does not require hot work at the installation site.

[0034] Optionally, the end face of the adjusting ring 20 can be a plane or a curved surface; there is no limitation on this. For example... Figure 4 As shown, a groove is provided on the adjusting ring 20, which is used to place a sealing element, such as a rubber sealing ring or a felt sealing ring, etc., and there are no restrictions on the type of sealing element.

[0035] According to another aspect of this utility model, a compressor system is provided, comprising a medium source, a compressor body, and a delivery pipeline system connected to the compressor body. The delivery pipeline system is the aforementioned delivery pipeline system. The compressor body is provided with a medium inlet. The delivery pipeline system includes an input port and an output port. The input port is connected to the medium source, and the output port is used to connect to the medium inlet. The delivery pipeline system delivers the driving medium output from the medium source into the compressor to drive the compressor to move. This delivery pipeline system can use completely prefabricated delivery pipe sections for on-site assembly, solving the problem that existing long pipes require secondary processing such as cutting and welding before assembly when installed on-site. This also avoids the problems of incorrect connections or the introduction of more deviations that may result from this method. Because it eliminates the need for on-site pipe cutting and welding, it is more adaptable to environments where open flames are strictly prohibited.

[0036] In summary, the present invention employs a slip-on flange 112 in the pipe section design. Utilizing the rotatable characteristic of its flange ring 1122, the flange ring 1122 can flexibly accommodate the position and state of the butt-welding flange 122 of the second pipe section 12 during assembly. This solves the problem in the prior art where, after the paired flanges in the pipeline are separately welded to their connecting pipes in the processing workshop according to the design, it is difficult to correctly reconnect the paired flanges on site due to profile deformation or different welding methods between the flanges and pipes.

[0037] Based on this, an adjusting ring 20 is installed between the first pipe section 11 and the second pipe section 12, accumulating all pipe processing tolerances and installation tolerances during installation onto this ring. This solves the problem of on-site pipe cutting, welding, and other flammable operations required due to variations in profile deformation and pipe manufacturing methods, which may result in discrepancies between the actual structural dimensions of the pipes and the design. The use of the slip-on flange 112 and the adjusting ring 20 makes complete prefabrication of the designed pipe sections possible, and the rotatable flange ring 1122 within the slip-on flange 112 effectively ensures the assembly between flanges.
