摘要（英）：

The utility model discloses a VHP conduction window door sealing structure which comprises a door frame and a conduction window door, wherein a first groove is formed at a matching part of the door frame and the conduction window door; a propping mechanism and a first sealing ring are arranged inside the first groove; and the opening of the first groove is formed in the first sealing ring. When the conduction window door is closed, the first sealing ring props out of the outer side of the opening under the action of the propping mechanism and is in sealed matching with the conduction window door. Due to adoption of the scheme, the problems that gases can leak from a conventional VHP conduction window door and the sealing effect is not good are solved, and the leakage risk can be thoroughly eliminated.
