Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0025] Refer to Figure 1 , Figure 4 and Figure 5The utility model provides an embodiment: including pipeline 1, the top side middle end fixed connection of pipeline 1 has maintenance pipe 2, the top side fixed connection of maintenance pipe 2 has installation pipe 3, sliding assembly includes the support block 12 of fixed connection in the outer wall of installation pipe 3, the middle end fixed connection of support block 12 has slide rod 6, the outer wall of slide rod 6 is connected in the arc clamping sleeve 4 slidingly, the outer wall of slide rod 6 is provided with compression spring 8, the front and rear ends of slide rod 6 are provided with lock block 7, the inner wall of pipeline 1 is provided with filter core body 15, the top end fixed connection of filter core body 15 has installation rod 16, the top end fixed connection of installation rod 16 has clamping plate 5, clamping assembly includes the arc limiting strip 18 of fixed connection in the outer wall of the both ends of pipeline 1, the inner wall of connecting sleeve 10 is opened with arc clamping groove, the arc limiting strip 18 is arranged in the inside of arc clamping groove, the outer wall fixed connection of connecting sleeve 10 has fixed block 11, elastic component includes the limiting rod 13 of fixed connection in the outer wall of fixed block 11, the outer wall slidingly connected in limiting rod 13 of arc sealing clamping sleeve 9, the outer wall of limiting rod 13 is provided with compensation spring 14;

[0026] Specifically, when installing the filter core, first, the filter core body 15 is placed into the pipeline 1 by means of the installation rod 16 and the clamping plate 5, ensuring that the sealing disc 17 is tightly attached to the inner wall of the maintenance pipe 2 and that sealing glue or a sealing ring is filled between the sealing disc 17 and the maintenance pipe 2 to form a good seal. Then, the position of the arc clamping sleeve 4 is adjusted by the sliding assembly. By changing the position of the lock block 7 on the outer wall of the slide rod 6, the deformation amount of the compression spring 8 is adjusted, and by means of the elastic force of the compression spring 8, the arc clamping sleeve 4 can be accurately clamped on the top side of the clamping plate 5, thereby realizing the fixation of the filter core and completing the installation process of the filter core. When connecting the pipeline 1, the arc limiting strips 18 at both ends of the pipeline 1 are accurately aligned with the arc clamping grooves in the inner wall of the connecting sleeve 10 and are inserted, and then the adjacent fixed blocks 11 are fixed by bolts to firmly install the connecting sleeve 10 at both ends of the pipeline 1. At the same time, the arc sealing clamping sleeve 9 is tightly attached to the connecting part of the pipeline 1 by the elastic force of the compensation spring 14 in the elastic assembly, which not only ensures the sealing property but also effectively avoids stress caused by slight deformation of the pipeline 1 when connected, thereby avoiding the adverse effects on the connection between the pipelines 1. When the filter core needs to be disassembled, the bolts fixing the adjacent fixed blocks 11 are unscrewed, and the connecting sleeve 10 is removed. Then, by adjusting the sliding assembly, the fixation of the arc clamping sleeve 4 on the clamping plate 5 is released, and the filter core body 15 can be smoothly taken out from the pipeline 1, and the entire operation process is simple and fast.

[0027] Reference Figures 2-4The compression spring 8 is connected to one end of the arc-shaped sleeve 4 and the other end of the compression spring 8 is connected to the lock block 7, the outer wall of the front and rear ends of the slide rod 6 and the inner wall of the lock block 7 are provided with threads, the adjacent two fixing blocks 11 are connected through bolts to fix the two connecting sleeves 10, the middle end of the mounting rod 16 is fixedly connected with the sealing disc 17, and the sealing disc 17 is arranged on the inner wall of the maintenance pipe 2;

[0028] Specifically, the compensation spring 14 is sleeved on the outer wall of the limiting rod 13, one end of the compensation spring 14 is connected with the fixing block 11, and the other end of the compensation spring 14 is connected with the arc-shaped sealing sleeve 9. After the device is installed, the compensation spring 14 is in a compressed or pre-tightened state and generates a continuous elastic force applied to the arc-shaped sealing sleeve 9. The elastic force makes the arc-shaped sealing sleeve 9 tightly adhere to the outer wall of the connecting part of the pipeline 1, fills the possible small gap, effectively prevents the leakage of liquid or gas, and guarantees the sealing of the pipeline 1 connection. When the pipeline 1 vibrates or is deformed due to external factors, the pipeline 1 will apply additional stress to the connecting part. At this time, the compensation spring 14 can play a role by virtue of its elastic properties. If the pipeline 1 vibrates, the compensation spring 14 will continuously stretch and contract during the vibration process, absorb the energy generated by the vibration, and relieve the impact force transmitted to the connecting part of the filter device due to the vibration, preventing the connecting part from loosening due to frequent vibration. When the pipeline 1 is deformed, the compensation spring 14 will stretch or compress accordingly according to the direction and degree of displacement, adapt to the change of the pipeline 1 by deforming itself, compensate for the stress generated thereby, and maintain the stability of the connection between the filter device and the pipeline 1.

[0029] Working principle: when installing the filter element, first put the filter element body 15 into the pipeline 1 through the mounting rod 16 and the clamping plate 5, so that the sealing disc 17 tightly adheres to the inner wall of the maintenance pipe 2. Then adjust the position of the arc-shaped sleeve 4 through the sliding assembly, adjust the deformation amount of the compression spring 8 by using the elastic force of the compression spring 8 and the position of the lock block 7 on the outer wall of the slide rod 6, ensure that the arc-shaped sleeve 4 is clamped on the top side of the clamping plate 5, realize the fixing effect, fix the clamping plate 5, complete the installation of the filter element. When connecting the pipeline 1, insert the arc-shaped limiting strips 18 at both ends of the pipeline 1 into the arc-shaped clamping grooves in the inner wall of the connecting sleeve 10, fix the adjacent fixing blocks 11 through bolts, and fix the connecting sleeve 10 at both ends of the pipeline 1. At the same time, the elastic force of the compensation spring 14 in the elastic assembly makes the arc-shaped sealing sleeve 9 tightly adhere to the pipeline connecting part, guarantees the sealing and ensures that the connection of the pipeline 1 will not be affected by the stress generated by slight deformation. When the filter element needs to be disassembled, first unscrew the bolts fixing the adjacent fixing blocks 11, remove the connecting sleeve 10, adjust the sliding assembly, loosen the fixation of the arc-shaped sleeve 4 to the clamping plate 5, and then take out the filter element body 15 from the pipeline 1, which is simple and fast.

[0030] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
