A sealing assembly 4 is provided at the bottom of the first pipe 1, which improves the sealing performance of the connection between the first pipe 1 and the second pipe 2;

[0019] During installation, the first pipe 1 and the second pipe 2 are connected through the flange plates 3 on the first pipe 1 and the second pipe 2, and then the connection part is sealed through the sealing assembly 4, thereby improving the sealing performance of the pipe connection part.

[0020] Refer to Figures 2-3 As shown in the figure, the sealing assembly 4 includes a lower sealing seat 5. The lower sealing seat 5 is arranged at the bottom of the first pipe 1. A first limiting ring 6 is fixedly connected inside the lower sealing seat 5. The first limiting ring 6 is sleeved on the first pipe 1. Card slots 7 are symmetrically formed at the top of the lower sealing seat 5. An upper sealing seat 8 is arranged at the top of the second pipe 2. The upper sealing seat 8 is arranged at the top of one side of the lower sealing seat 5. The lower sealing seat 5 and the upper sealing seat 8 have the same size and shape. A clamping block 9 is symmetrically and fixedly connected to the bottom of the upper sealing seat 8. The positions and sizes of the card slots 7 and the clamping blocks 9 are correspondingly arranged, which is convenient for the card slots 7 and the clamping blocks 9 to be spliced. A second limiting ring 10 is fixedly connected inside the upper sealing seat 8. The second limiting ring 10 is sleeved on the second pipe 2. The first limiting ring 6 and the second limiting ring 10 are both arranged at the rear side of the flange plate 3. A plurality of upright columns 11 are fixedly connected to both the first limiting ring 6 and the second limiting ring 10.
