▎ 摘　　要

NOVELTY - The device has a flat vehicle (101) sliding along extending direction of a slide rail (14). A sample boat (4) moves with displacement of the flat plate vehicle. A low temperature cooling chamber A and B (3,10) are provided with a sealing valve A and B (5,9) at one end of a water cooling flange (6). The flat vehicle and a sampling rod A (15) connected by a pusher device A (1) slides along slide rail into a high temperature process chamber (7). The sampling rod connected by a pusher device B (12) slides along a slide rail and pulled into the cooling chamber B. USE - Device for preparing flowing water type graphene film. ADVANTAGE - A water cooled retaining ring which is provided in inner wall of the outer flange avoids the damage of the heat radiation generated by the working environment. Thereby ensures reliability of the seal and prolong service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing flowing water type graphene film. DESCRIPTION OF DRAWING(S) - The drawing shows the front view of the device.
