Annular seal for a parallel plate slide used for blocking pipelines for gaseous/liquid media comprises an inner wall, an outer wall, an inward-facing bevel, a sealing ring body, axial membranes, and a hollow, bellows-shaped annular spring

摘要

Annular seal for a parallel plate slide comprises an annular inner wall (11), an annular outer wall (12), a disk-shaped inward-facing bevel (14), and a sealing ring body surrounding a sealing edge base (10) on the side facing a blocking plate (3). Axial membranes (13) are tightly connected on the side facing the blocking plate to the inner diameter and the outer diameter of the sealing edge base and on the side facing a housing (1) to the ends of the inner wall, the outer wall and the outer diameter and inner diameter of the bevel. A hollow, bellows-shaped annular spring (6) lies within the sealing ring body and is supported on the bevel and the inner side of the sealing edge base. A free space (7) is located behind the bevel.
