The No. 1 steel pipe 1 and the No. 2 steel pipe 2 are slidably sleeved with an extrusion ring 14, a spacer ring 10 is fixed in the middle of the extrusion ring 14, the sealing ring 9 is installed on the inner side of the spacer ring 10, and blocks 11 are connected to both sides of the extrusion ring 14. Card grooves 7 are provided on both sides of the connecting pipe 3 near the card block 11, and the cross-sectional shape of the card block 11 and the card groove 7 is set to be trapezoidal.

[0025] During specific implementation, since the sealing performance of the pipeline connection assembly of the stainless steel pipe is not high and it is inconvenient to position and dock during connection, the joint of the No. 1 steel pipe 1 and the No. 2 steel pipe 2 can be sealed by the sealing ring 9, and then the extrusion ring 14 can seal the connection between the No. 1 steel pipe 1 and the No. 2 steel pipe 2 and the connecting pipe 3 again. When the extrusion ring 14 is inserted into the connecting pipe 3, the extrusion ring 14 drives the card block 11 to be inserted into the card groove 7, and the extrusion ring 14 can be positioned and docked, thereby improving the sealing performance and convenience of the pipeline connection assembly.

[0026] See also Figures 1-6A pipe connection assembly includes a connecting pipe 3 and a sealing ring 9. The outer side of the connecting pipe 3 is provided with a No. 1 clamping ring 4 and a No. 2 clamping ring 5. The sealing ring 9 is installed on the inner side of the spacer ring 10. One side of the No. 1 clamping ring 4 and the No. 2 clamping ring 5 is connected to a docking mechanism 6. A through hole 12 is opened on the inner wall of the connecting pipe 3 near the docking mechanism 6. Both ends of the connecting pipe 3 are slidably sleeved with an extrusion ring 14.

Only three holes need to be opened on the stainless steel pipe, which is more convenient and improves the practicality of the pipeline connection assembly.

[0028] Working principle: When using the pipeline connection assembly and the stainless steel pipe, first, the extrusion ring 14 is sleeved on the outside of the No. 1 steel pipe 1 and the No. 2 steel pipe 2, and then one end of the No. 1 steel pipe 1 and the No. 2 steel pipe 2 is inserted into the connecting pipe 3, and then the extrusion ring 14 is pushed into the connecting pipe 3 to seal the outside of the No. 1 steel pipe 1 and the No. 2 steel pipe 2. At the same time, the extrusion ring 14 drives the clamping block 11 to be clamped into the clamping groove 7 to position the extrusion ring 14, and then the No. 1 clamping ring 4 and the No. 2 clamping ring 5 are sleeved on the outside of the connecting pipe 3, and at the same time, the docking mechanism 6 limits the No. 1 steel pipe 1 and the No. 2 steel pipe 2, which facilitates the stable connection of the stainless steel pipes and improves the practicality and stability of the pipeline connection assembly.
