Seal assembly for the annular gap between the container wall of a vertical cylindrical container for fluid and an outer wall of a floating cover

摘要

the invention relates to a dichtungsanordnung for the annular gap (9) between the vessel wall (2) of a liquid (3) certain vertical rundbehu00e4lters (1) and an outer wall (8) of a floating cover (5) with at least one circumferential in the vessel wall (2), 1996 - primu00e4rdichtung (11), the at least one gleitblech (13) includesat least one sekundu00e4rdichtung (12) and at least one dichtungsmembran (16). primu00e4rdichtung (11) and sekundu00e4rdichtung (12) through a system (26, 26a - 26f). at least one first to dichtmembran (21) are provided, the annular gap (9) of the upper end (19) of the sekundu00e4rdichtung (12) to the top (22) of the floating cover (5) spans.the height of the sekundu00e4rdichtung (12) is at least half the height of the gleitblechs (13) of the primu00e4rdichtung (11). the system (26, 26a - 26f) attack the gleitblech (13) of the primu00e4rdichtung (11) and keeps the primu00e4rdichtung (11) with its upper edge (17) immediately above the maximum possible depth (4, 4 ') of the floating cover (5).in the field of ringspalts (9), a second dichtmembran (20, 20 ') is arranged. the sekundu00e4rdichtung (12) is another at the upper end (22) of the floating cover (5) fortified federelement (29, 50) is pressed.
