[0024] The side surface of the installation disc 4 is provided with a flexible sealing ring 7 and a silica gel ring 5, the flexible sealing ring 7 and the silica gel ring 5 are distributed left and right, and the flexible sealing ring 7 and the silica gel ring 5 are in close contact with the inner wall of the pipeline during use. The diameter of the flexible sealing ring 7 is larger than that of the silica gel ring 5, and the flexible sealing ring 7 is in contact with the inner wall of the pipeline during use. The left surface of the silica gel ring 5 is provided with a reinforcing groove 6, and the right end of the flexible sealing ring 7 is located in the reinforcing groove 6 during use. The flexible sealing ring 7 and the silica gel ring 5 cooperate with the installation disc 4 to form a sealing structure, wherein the flexible sealing ring 7 is used to seal the pipeline, and the silica gel ring 5 cooperates with the installation disc 4 to form an isolation mechanism for isolating the flexible sealing ring 7 and the baffle door, thereby reducing the hidden danger of the flexible sealing ring 7 and the baffle door being eroded by gas.

[0025] The right surface of the fixed suction disc 1 and the left surface of the installation disc 4 are respectively provided with a steering joint 8 and a connecting block 3. The left surface of the steering joint 8 is rotatably connected with the fixed suction disc 1, and the right end of the steering joint 8 is fixedly connected with the left surface of the lead screw 2. The right surface of the connecting block 3 is fixedly connected with the installation disc 4. The overturning direction of the steering joint 8 is the same as the overturning direction of the docking disc 9 entering the receiving cavity 10. The steering joint 8 is used to provide the lead screw 2 with the conditions of rotation and inclined overturning, thereby improving the flexibility of the lead screw 2 during action. The upper surface of the steering joint 8 is fixedly connected with a limiting plate 13. The lower end of the limiting plate 13 is clamped with the left end of the lead screw 2 during use. The existence of the limiting plate 13 is used to limit the activity range of the lead screw 2, thereby improving the stability of the lead screw 2 during action.

[0027] Working principle: when installing the device, first add the silica gel ring 5 and the flexible sealing ring 7 to the surface of the installation disc 4 in sequence, then push the installation disc 4 into the pipeline through the baffle door opening in a horizontal manner by manually compressing the silica gel ring 5 and the flexible sealing ring 7, and then manually overturn the installation disc 4 to seal the pipeline. Then adjust the length of the lead screw 2 according to the length of the overturning part of the door panel when the door panel in the baffle door is opened. First, push the docking disc 9 in the lead screw 2 into the receiving cavity 10, and then adsorb the fixed suction disc 1 to the surface of the door panel in the baffle door, so as to complete the installation work of the device.

[0028] When the sealing device needs to be maintained, only the flexible sealing ring 7 needs to be replaced. When the flexible sealing ring 7 is replaced, the inclined screw rod 2 is first flipped through the receiving cavity 10 in the direction penetrating the lower surface of the connecting block 3, so that the restriction of the flexible sealing ring 7 by the screw rod 2 is released, and the replacement work of the flexible sealing ring 7 can be performed. When the residual gas in the pipeline needs to be discharged, the edge of the installation disc 4 is pushed by a long rod from the outside, so that the installation disc 4 is tilted, and the sealing effect of the flexible sealing ring 7 and the silica gel ring 5 on the pipeline is released. The compression and deformation characteristics of the flexible sealing ring 7 and the silica gel ring 5 themselves provide the installation disc 4 with the adjustment of tilting at a certain angle.
