SEALING ASSEMBLIES AND METHODS FOR SEALING AN ELONGATE MEMBER

摘要

A sealing assembly for forming a seal about an elongate object includes a resilient seal member and a loading mechanism. The resilient seal member includes an inner wall surface defining a channel to receive the elongate object. The seal member has first and second opposed sides. The loading mechanism includes a first pressure member on the first side of the seal member; a second pressure member on the second side of the seal member; a biasing member on the second side of the seal member and interposed between the seal member and the second pressure member; and an adjustable displacement mechanism accessible and operable from the first side of the seal member to displace the first and second pressure members relative to one another to selectively apply a compressive load to the seal member such that the inner wall surface is expanded inwardly to exert a sealing pressure on the elongate object.
