Description

TECHNICAL FIELD

[0001] The present utility model relates to a pipeline connection assembly, in particular to a pipeline connection assembly for conveying fluids such as chemical solutions, water, and the like. BACKGROUND

[0002] Chemical solutions or water need to be conveyed in many manufacturing processes, such as when a pharmaceutical plant produces medicine, or when a semiconductor plant coats a wafer surface to form a thin film of uniform thickness. As a result, pipelines and pipeline connectors are needed in many industries. However, as plants and machines become more complex, the space available for installing and replacing pipelines becomes smaller. As a result, there is a lack of space to allow the operation of inserting or pulling a pipeline out of a connector. Therefore, a new pipeline connection assembly is needed to solve this problem.

[0003] For example, PFA (perfluoroalkoxy) pipelines are widely used in the production of chemicals, pharmaceuticals, food, semiconductors, and the like. However, traditional PFA pipeline connectors require special processes, and the quality of construction affects their service life and stability. In addition, when connecting two PFA pipes during installation, displacement space parallel to the direction of the pipes is needed to allow the pipes to be inserted or pulled out of the connector. Insufficient space makes it difficult to disassemble and assemble the pipeline connection assembly, and the pipelines cannot be removed from the connector during installation and maintenance. If a pipeline is forcibly installed, it can cause other connected pipelines to be damaged by being pulled and pushed. Moreover, a hot air gun, an expander, a cleaning cloth, water, protective glasses, and the like are needed to cut the PFA pipeline, heat the PFA, and then insert the expander. This traditional installation method is time-consuming, labor-intensive, and costly. SUMMARY

[0004] Traditional pipeline connection assemblies require space to allow the pipelines to be inserted into or pulled out of the connector in a direction parallel to the pipelines. The pipeline connection assembly of the present utility model solves the problem of lack of space by allowing the pipelines to be inserted into or pulled out of the connector in a direction perpendicular to the pipelines.

[0055] A pipeline connection assembly according to embodiments of the present application will now be described in detail with reference to the drawings.

[0056] Figure 1 is a perspective view of a pipeline connection assembly 100 according to embodiments of the present application. Figure 2 is Figure 1 is an exploded view of the pipeline connection assembly 100 in . The pipeline connection assembly 100 includes a first pipeline 110, a second pipeline 120, a gasket 130, and a sleeve 140. The first pipeline 110 has a first end 112, and the second pipeline 120 has a second end 122. The connection faces of the first end 112 and the second end 122 each have a groove G. Optionally, the groove G is a concentric circle. By way of example and not limitation, a pin 150 is U-shaped and inserted into the sleeve 140 by both ends.

[0057] Figure 3a is Figure 2is an exploded view of the assembly of the first end 112, the second end 122, and the grommet 130. The grommet 130 has a through hole 132 surrounded by protrusions P on both sides. Figure 2 is a groove (not shown) of the first end 112 of the first line 110 that mates with Figure 3a the protrusions P of the grommet 130 shown. Optionally, the protrusions P are concentric circles. Figure 2 is a groove G of the second end 122 of the second line 120 that mates with Figure 3a the protrusions P of the grommet 130 shown. Optionally, the protrusions P are concentric circles.

[0058] Figure 3b is Figure 2 is an exploded view of the assembly of the first end 112, the second end 122, and the grommet 130. The grommet 130 has a through hole 132 surrounded by protrusions P on both sides. Figure 2 and Figure 3. Optionally, the sleeve 140 has a texture, such as protrusions 148, on the outer wall to provide friction when the sleeve 140 is rotated to engage or disengage the second end 122.

[0059] Figure 4 is Figure 1 is a side view of the assembly, Figure 5 is Figure 4 is a cross-sectional view of the assembly in section A-A. As shown, Figure 5 the sleeve 140 has a first opening 141a at a first end 141 and a second opening 142a at a second end 142. The inner wall of the second end 142 has threads. The second end 122 has threads to mate with the threads of the second end 142 from the second opening 142a. The first end 112 has the same threads as the second end 122, thus preventing the first end 112 from being screwed into the second end 142 of the sleeve 140 from the first opening 141a. Further, since only the inner wall of the second end 142 of the sleeve 140 has threads, when the first end 112 and the second end 122 have the same threads and both have to be installed into the sleeve 140, such a structure enables the sleeve 140 to move to accommodate the second line 120. When the sleeve 140 moves to accommodate only the second line 120, the first end 112 is not restricted by the sleeve 140 and can move in a direction perpendicular to the first line 110. To secure the first line 110 with the sleeve 140, as shown, Figure 4 a latch 150 is inserted into the first end 141 of the sleeve 140, thus preventing the first end 112 from disengaging from the sleeve 140, as shown.
