The outer side of the sealing block 1001 is movably connected to the sealing ring 1002. The outer diameter of the sealing ring 1002 is smaller than the inner diameter of the sealing block 1001. The sealing ring 1002 and the sealing block 1001 form a snap-fit ​​structure.

[0027] like Figure 2-3As shown, the first flange 2 and the second flange 3 cooperate with each other, the tee pipe 1 and the connecting pipe 7 can be connected by the cooperation of the first flange 2 and the second flange 3, and then the first flange 2 and the second flange 3 can be fixed together by the cooperation of the fixing screws 5 and the nuts 4, so that different connecting pipes 7 and the tee pipe 1 can be connected. At the same time, the sealing block 1001 and the sealing gasket 1003 on one side of the first flange 2 can be inserted into the second flange 3. After the sealing block 1001 is inserted into the second flange 3, the sealing ring 1002 will also be inserted into the groove inside the sealing block 1001, thereby strengthening the sealing between the first flange 2 and the second flange 3.

[0028] A fixing screw 5 passes through one side of the second flange 3, and external threads are evenly provided on the outer wall of the fixing screw 5. Internal threads that cooperate with the external threads are evenly provided on the inner wall of the nut 4. The fixing screw 5 and the nut 4 are threadedly connected, and the nut 4 is movably connected to one side of the fixing screw 5.
