It is then guided into the matching branch pipe 19 through the docking inlet branch pipe 25 and the docking inlet valve pipe 24, and then into the sealing sleeve 20. The superheated water mixes in the sealing sleeve 20, which helps with the subsequent injection start-up work and completes the work.
