| 摘要 |
The invention relates to a sealing system for media-carrying parts, especially for use in asepsis, comprising a sealing ring (14), preferably a toroidal sealing ring, which is placed on a sealing seat for the purpose of sealing the parts. Said sealing seat is constituted by a sealing channel (22) that substantially surrounds the sealing ring. The sealing channel (22) is composed of sealing surfaces (21a, 21b) of both parts (12, 13) and defines between said parts and between said sealing surfaces a sealing groove (30) into which the sealing ring (14) is deformed when the parts are axially braced against each other until they come into contact. A separating joint (41) adjoins the sealing channel on a side facing away from the sealing groove (30). The sealing channel (22) has at least one expansion chamber (35, 57a, 57b) that deviates from the undeformed cross-section of the sealing ring. Said expansion chamber (35, 57a, 57b) is arranged substantially opposite the sealing groove (30). The sealing ring (14) is deformed into the expansion chamber (35, 57a, 57b) by outer influences, especially by the bracing force for joining the parts. |
