Seal assembly in a conduit connection

Abstract

Abstract A SEAL ASSEMBLY FOR A CONDUIT CONNECTION INCLUDING A FIRST AND A SECOND CONDUIT PART, EACH HAVING AN AXIALLY EXTENDING FLOW PASSAGE AND AN END SURFACE RADIALLY INTERSECTING THE FLOW PASSAGE. EACH OF THE CONDUIT PARTS INCLUDES AN INTERNAL SEALING CAVITY ADJACENT THE END SURFACE AND RADIALLY OFF-SET FROM THE FLOW PASSAGE. A COMPOSITE SEALING RING IS INTERPOSED BETWEEN THE CONDUIT PARTS AND EXTENDS INTO THE TWO SEALING CAVITIES. THE COMPOSITE SEALING RING INCLUDES A CENTRAL RIM PORTION FROM WHICH EXTEND TWO GENERALLY AXIALLY DISPOSED LIP PORTIONS PROJECTING OPPOSITELY OUTWARDLY INTO THE CONDUIT SEALING CAVITIES. AN ELASTOMERIC SEALING MEMBER EXTENDS PERIPHERALLY ABOUT EACH OF THE LIP PORTIONS AND INTO CONFORMING ENGAGEMENT WITH THE INTERNAL SEALING SURFACES OF THE CONDUIT PARTS. THE COMPOSITE SEALING RING ALSO INCLUDES TWO GENERALLY AXIALLY DISPOSED FLEXIBLE SEALING FLANGES EXTENDING OPPOSITELY OUTWARDLY FROM THE CENTRAL RIM AT A POSITION RADIALLY OUTWARDLY FROM THE LIP PORTIONS. A PORTION OF EACH OF THE ELASTOMERIC SEALING MEMBERS ENGAGES EACH OF THE FLEXIBLE SEALING FLANGES. A CLAMPING ASSEMBLY IS POSITIONED ABOUT THE CONDUIT PARTS TO DRAW THEM TOGETHER AND FORCE THE ELASTOMERIC SEALING MEMBERS TO REDISTRIBUTE THEIR VOLUME AND CONFORMINGLY ENGAGE THE INTERNAL CONDIT SEALING SURFACES. THE CLAMPING ASSEMBLY IS ALSO OPERATIVE TO DRAW THE CONDUIT PARTS FURTHER TOGETHER AND CAUSE THE PORTIONS OF THE ELASTOMERIC MEMBERS WHICH ENGAGE THE FLEXIBLE SEALING FLANGES TO REDISTRIBUTE THEIR VOLUME AND FORCE THE FLEXIBLE FLANGES RADIALLY OUTWARDLY INTO SEALING ENGAGEMENT WITH THE INTERNAL CONDUIT SEALING SURFACES.
