▎ 摘　　要

NOVELTY - The airlock has a hollow-shaped shell (1) connected with a rotating shaft (2) that is connected with a separating plate. Left and right ends of the separating plate are connected with an end plate that is connected with the shell. An inner wall of the shell is fixed with a sealing strip. The sealing strip is composed of 18-22 wt. % of graphite, 8-12 wt. % of carbon fiber and 3-10 wt. % of graphene. The sealing strip is coated with wear-resisting polyfluoroethylene material. The end plate is connected with the sealing strip that is formed with a T-type groove. USE - High vacuum-type airlock. ADVANTAGE - The airlock has better sealing bar processing effect and prolonged service life. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a high vacuum-type airlock.
