Detailed Implementation

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides an expander assembly for intelligent variable load regulation in a chemical air separation system, including an expander body 1 and a connecting pipe 2. An installation pipe 3 is fixedly connected to the side wall of the expander body 1. A sliding column 4 is slidably arranged on the circumferential side of the installation pipe 3. One end of the sliding column 4 extends into the installation pipe 3 and an installation plate 5 is fixedly installed on its outer surface. A tension spring 6 is sleeved on the outer side of the sliding column 4. A locking block 18 is fixedly installed on the side wall of the installation plate 5. The two ends of the tension spring 6 are respectively connected to the inner side wall of the installation pipe 3 and the side wall of the installation plate 5. An arc-shaped top block 7 is fixedly installed on the end of the sliding column 4 that extends out of the installation pipe 3. An annular pressure plate 8 is slidably arranged on the outer surface of the installation pipe 3.

[0024] A tube 9 is fixedly installed on the side wall of the connecting pipe 2. A locking hole 10 matching the sliding column 4 is opened on the circumferential side of the tube 9. The locking block 18 is inserted into the locking hole 10 and slidably set therewith. During installation, after inserting the tube 9 on the side wall of the connecting pipe 2 into the installation pipe 3, the annular pressure plate 8 on the outside of the installation pipe 3 is pulled. During the sliding process, the annular pressure plate 8 squeezes the arc-shaped top block 7 on the outside of the installation pipe 3, squeezing the arc-shaped top block 7 inward, driving the sliding column 4 to move inward, so that the locking block 18 is inserted into the locking hole 10 opened on the circumferential side of the tube 9, thereby realizing the quick fixed installation. When it is necessary to quickly disassemble the fitting, the annular pressure plate 8 is pulled towards the expander body 1. At this time, the arc-shaped top block 7 loses the squeezing force of the annular pressure plate 8. The installation plate 5 and the sliding column 4 are subjected to the rebound force of the tension spring 6, which drives the locking block 18 to slide outward. The sliding column 4 locks the hole 10, releasing the locking fixation of the tube 9. At this time, it can be directly pulled out for quick disassembly.

[0025] Preferably, a sealing ring 11 is fixedly installed on the inner wall of the installation tube 3. The radius of the sealing ring 11 is the same as the radius of the insertion tube 9. An inner tube 12 is fixedly installed on the side wall of the insertion tube 9. The inner tube 12 extends into the sealing ring 11 and slides therewith. The sealing effect during installation can be improved by the sealing ring 11.

[0026] As can be seen from the above, during installation, after inserting the insertion tube 9 on the side wall of the connecting pipe 2 into the installation pipe 3, the annular pressure plate 8 on the outside of the installation pipe 3 is pulled. During the sliding process, the annular pressure plate 8 squeezes the arc-shaped top block 7 on the outside of the installation pipe 3, squeezing the arc-shaped top block 7 inward, which drives the sliding column 4 to move inward, so that the locking block 18 is inserted into the locking hole 10 opened on the side of the insertion tube 9, thereby realizing the quick fixing and installation process. When it is necessary to quickly disassemble the fitting, the annular pressure plate 8 is pulled towards the expansion machine body 1. At this time, the arc-shaped top block 7 loses the squeezing force of the annular pressure plate 8, and the installation plate 5 and the sliding column 4 are subjected to the rebound force of the tension spring 6, which drives the locking block 18 to slide outward. The sliding column 4 locks the hole 10, releasing the locking and fixing of the insertion tube 9. At this time, it can be directly pulled out for quick disassembly.

[0027] Example 2: Based on Example 1, a limiting rod 13 is fixedly installed on the side wall of the expander body 1. The annular pressure plate 8 passes through the limiting rod 13 and is slidably set therewith. The limiting rod 13 passes through the side wall of the annular pressure plate 8 and is fixedly connected to an anti-detachment plate 15. The limiting rod 13 can facilitate the limiting treatment when the annular pressure plate 8 is pulled. The anti-detachment plate 15 can reduce the possibility of the annular pressure plate 8 falling off.

[0028] Preferably, a compression spring 14 is sleeved on the outer side of the limiting rod 13. The two ends of the compression spring 14 are connected to the side wall of the annular pressure plate 8 and the side wall of the expander, respectively. The elastic coefficient of the compression spring 14 is greater than that of the tension spring 6. Through the compression spring 14, the annular pressure plate 8 can be continuously squeezed. The rebound force keeps the annular pressure plate 8 outside the arc-shaped top block 7, thereby improving the stability of the annular pressure plate 8.

[0029] Furthermore, the side wall of the installation pipe 3 is provided with positioning grooves 16 distributed at equal angles, and the side wall of the connecting pipe 2 is fixedly installed with a positioning rod 17 that matches the positioning groove 16. The positioning rod 17 is inserted into the positioning groove 16 and slidably set therewith. The positioning groove 16 and the positioning rod 17 can be used to assist in positioning during installation.

[0030] As can be seen from the above, during installation, after pulling the annular pressure plate 8, inserting the insertion tube 9 on the side wall of the connecting tube 2 into the installation tube 3, and then releasing the annular pressure plate 8, the annular pressure plate 8 is driven by the rebound force of the compression spring 14 to move towards the arc-shaped top block 7, causing the annular pressure plate 8 to press the arc-shaped top block 7 inward, driving the sliding column 4 to move inward, so that the locking block 18 is inserted into the locking hole 10 opened on the side of the insertion tube 9, thereby realizing the quick fixing and installation process. When moving, the limiting rod 13 can be used to limit the annular pressure plate 8 when it is pulled. Before installation, the positioning groove 16 and the positioning rod 17 can be used to assist in positioning during installation.
