[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figures 1-5This utility model discloses a chemical material pipeline purging device, including a purging device body 1 and a connecting pipe 2. The purging device body 1 is the pipeline purging device, which is an existing structure, that is, it is installed at the end of the pipeline for purging the pipeline. The connecting pipe 2 is a connecting structure. The purging device body 1 includes a purging port 11, through which the purging device body 1 discharges air. The purging port 11 is respectively provided with a sealing ring 12 and a four-port flange 13, that is, the pipeline flange can be directly connected through the four-port flange 13 and sealed by the sealing ring 12.

[0027] A first air outlet 21 is provided on the outside of the connecting pipe 2, which is used to extend the purge port 11. A second air outlet 22 is provided on the top of the connecting pipe 2, which is used to adjust the angle of the purge port 11. An eight-port flange 14 is provided on the inside of the connecting pipe 2, which is connected to a four-port flange 13. The sealing ring 12 is in contact with the connecting pipe 2. The eight-port flange 14 and the four-port flange 13 are connected by bolts and nuts, so that the connecting pipe 2 is connected to the purge port 11. By changing the connection angle of the eight-port flange 14, the angle of the second air outlet 22 can be changed. This allows for flexible adjustment according to different pipeline conditions, making it easy to connect the air outlet to the pipeline.

[0028] Both the first air outlet 21 and the second air outlet 22 are equipped with ball valves 23. The two ball valves 23 are used to open and close the first air outlet 21 and the second air outlet 22 respectively. The outer side of the ball valve 23 is provided with external teeth 24. The two external teeth 24 mesh with each other. When one ball valve 23 is rotated open, the other ball valve 23 is reversed and closed through the external teeth 24. Conversely, when one is closed, the other is opened, thereby preventing the two ball valves 23 from being opened at the same time. The outer side of the first air outlet 21 and the second air outlet 22 is provided with flanges for connecting pipelines.

[0029] A fixing component is provided on the outer side of the connecting pipe 2. The fixing component includes a mounting base 3, which is an installation structure. The top of the mounting base 3 is provided with a hexagonal groove 31. A hexagonal block 32 is slidably arranged inside the hexagonal groove 31. A square block 33 is provided on the hexagonal block 32. A threaded opening 34 is provided on the outer side of the hexagonal groove 31. A bolt 35 is provided inside the threaded opening 34. The bolt 35 is threadedly connected to the threaded opening 34 and rotatably connected to the hexagonal block 32. A square opening 25 is provided on the inner side of the ball valve 23 of the second air outlet 22. The square opening 25 is located at the center of the ball valve 23. The square block 33 is installed and removed in the square opening 25. When the ball valve 23 is opened and closed, the square block 33 is engaged with the square opening 25. That is, by rotating the bolt 35 on the outside, the hexagonal block 32 is slidable and the square block 33 is inserted into the square opening 25, which fixes the two ball valves 23 and prevents the ball valves 23 from opening or leaking before use.

[0030] A sliding groove 4 is provided on the outer side of the mounting base 3. A sliding member 42 is slidably arranged inside the sliding groove 4. A fixing block 43 is provided on the top of the sliding member 42. A fixing port 44 is provided on the bottom outer side of the bolt 35. The fixing block 43 is installed and removed in the fixing port 44. A first spring 41 is provided on the bottom inner side of the sliding groove 4. The first spring 41 is connected to the sliding member 42. After the square block 33 is inserted into the square port 25, the fixing port 44 is just aligned with the fixing block 43. That is, the first spring 41 pushes the sliding member 42, so that the fixing block 43 is inserted into the fixing port 44, thus fixing the bolt 35 and preventing the bolt 35 from rotating during use. A limit port 45 is provided on the inner side of the sliding member 42. A push block 5 is slidably arranged inside the limit port 45. A second spring 51 is provided on the inner side, and a limit block 52 is provided on the second spring 51. The limit block 52 is installed and removed in the limit port 45. By pulling the sliding member 42 down, the limit port 45 is aligned with the limit block 52. At this time, the fixing block 43 is removed in the fixing port 44, that is, the fixing of the bolt 35 is released. The second spring 51 pushes the limit block 52, so that the limit block 52 is inserted into the limit port 45, thereby locking the sliding member 42 and preventing it from moving, so that the bolt 35 can be rotated. By pressing the pushing block 5 on the outside, the limit block 52 is pushed out of the limit port 45, and the fixing of the sliding member 42 is released. When the limit block 52 is not in the limit port 45, the sliding member 42 is always pressed on the limit block 52.

[0031] The working principle of this utility model is as follows: the eight-port flange 14 and the four-port flange 13 are connected by bolts and nuts, so that the connecting pipe 2 is connected to the purge port 11. By changing the connection angle of the eight-port flange 14, the angle of the second air outlet 22 can be changed, which can be flexibly adjusted according to different pipeline conditions, so that the air outlet can be easily connected to the pipeline. When one ball valve 23 is turned open, the other ball valve 23 is reversed and closed by the transmission of the external gear 24, thus avoiding the simultaneous opening of the two ball valves 23. When the ball valves 23 are opened and closed, the square block 33 is engaged with the square opening 25. That is, by rotating the bolt 35 on the outside, the hexagonal block 32 slides and the square block 33 is inserted into the square opening 25, thus fixing the two ball valves 23 and preventing the ball valves 23 from opening and leaking before use. The first spring 41 pushes the sliding member 42, so that the fixing block 43 is inserted into the fixing port 44, thus fixing the bolt 35 and preventing the bolt 35 from rotating when the device is in use.
