[0021] In this embodiment, if Figure 2 As shown, in order to ensure good sealing performance between the one-way ventilation socket 4 and the pipeline connection and increase the contact strength of the connection, the strengthened sealing assembly includes two inflatable sealing rings 12, two pumping sections 13 and two crimping connecting rods 14. The inflatable sealing rings 12 are arranged at the ends of the one-way ventilation socket 4 and the air holes of the inflatable sealing rings 12 are respectively connected to the corresponding pumping sections 13, the piston rod ends of the pumping sections 13 are connected to the crimping connecting rods 14, and the crimping connecting rods 14 are plugged into the side of the one-way ventilation socket 4; the pumping distance of the piston rod inside the pumping section 13 is the length of the one-way ventilation socket 4.
