During the use of the sealing block 11, not only the sealing block 11 is slid on the connection between the first pipe 1 and the second pipe 2 to achieve the first seal, and the sealing gasket 10 is used to perform the second seal on the gap, which has a multiple sealing effect in use, but also the first sealing ring 14 is placed inside the first connecting groove 12. The second sealing ring 15 is placed inside the second connecting groove 16 to seal the sealing block 11. The gap between the first sealing ring 14 and the second sealing ring 15 is further sealed by the sealing strip 13 to better prevent temperature loss during use. It is then fixed with the second bolt 18 to prevent it from falling off. When the first bolt 8 is taken out from the inside of the first thread groove 4 and the second thread groove 7, the collar 5 can be quickly replaced and maintained during maintenance. After the collar 5 is removed, the sealing block 11 can be maintained and replaced. The sealing block 11 can be quickly replaced and maintained during use.
