[0025] In the embodiment of the utility model, the sealing element comprises a rubber sealing ring 3, the outer side of the rubber sealing ring 3 is fixedly connected with an annular fixed plate 31, the inner walls of the first connecting pipe 12 and the second connecting pipe 13 are both provided with annular fixed grooves 32 matched with the annular fixed plate 31, the annular fixed plate 31 is clamped in the annular fixed groove 32, and the inner side of the rubber sealing ring 3 is provided with a plurality of reinforcing ribs 33 arranged in an annular array.

[0026] It should be noted that the rubber sealing ring 3 is a core component, directly contacts the fluid medium and prevents leakage from the pipeline connection. The annular fixed plate 31 on the outer side is tightly clamped with the annular fixed groove 32 on the inner wall of the first connecting pipe 12 and the second connecting pipe 13, ensuring the stable installation of the rubber sealing ring 3 and preventing displacement during operation. The plurality of reinforcing ribs 33 arranged in an annular array on the inner side enhance the structural strength of the rubber sealing ring 3, allowing it to better withstand the pressure of the fluid in the pipeline and preventing deformation due to excessive pressure, further ensuring the sealing effect.

[0029] The working principle of the pipe plate flange connecting device provided by the utility model is as follows: first, connect the first connecting pipe 12 with one actual pipeline to be connected, and connect the second connecting pipe 13 with another actual pipeline to be connected. Then, align the annular connecting block 22 on the second flange plate 11 with the annular groove 21 on the first flange plate 1 and insert it, at this time, the annular sliding block 2 can be flexibly slid in the annular groove 21, adjust the relative angle of the first flange plate 1 and the second flange plate 11, align the bolt holes of the two, and then tightly connect the first flange plate 1 and the second flange plate 11 by bolts and nuts passing through the bolt holes, completing the preliminary butt joint installation of the pipeline.

Since the annular slider 2 can flexibly slide in the annular groove 21, and the annular connecting block 22 cooperates with the annular slider 2, when the second flange plate 11 is rotated, the second flange plate 11 can be rotated along the annular slider 2 in the annular groove 21 through the annular connecting block 22, thereby realizing the change of the relative angle of the pipeline. After adjusting to the appropriate angle, the bolts and nuts are tightened again to fix the positions of the first and second flange plates, and the angle adjustment of the pipeline is completed.
