Description
Gegenstand der Erfindung ist ein Dichtungsring von keilförmigem Querschnitt für Rohrvexbindungen mit einer sich über die Enden der zu verbindenden Rohre ersitrecfcen-5' den Hülse mit abgeschrägten Innenrändern (Überschiebmuffe), bei der die Dichtungsringe axial durch Flansche und Schraubbolzen zusammengepreßt werden.The invention relates to a sealing ring of wedge-shaped cross-section for pipe vex connections with a Ends of the pipes to be connected ersitrecfcen-5 ' the sleeve with bevelled inner edges (sleeve sleeve), in which the sealing rings are axially pressed together by flanges and bolts.
Die Erfindung besteht darin, daß die zur Berührung mit der Flüssigkeit gelangenden Keilspitzen der Dichtungsringe.-geschlitzt sind. Hierdurch ist erreicht, daß die Preßdichtung noch eine zusätzliche Lippendichtung erhält, da die durch die Schlitzung der Keilspitze gebildeten Lippen sich beim Festschrauben der Dichtung fest gegen die Hülse und das Rohrende legen.The invention consists in that the coming into contact with the liquid Wedge tips of the sealing rings are slotted. This ensures that the press seal an additional lip seal is also given, as the one formed by the slitting of the wedge tip Lips firmly against the sleeve and the end of the pipe when the seal is screwed on place.
In der Zeichnung ist ein Ausführungsbeispiel eines Dichtungsringes nach der Erfindung in einer Rohrverbindung dargestellt.In the drawing is an embodiment of a sealing ring according to the invention shown in a pipe connection.
Zwischen der mit abgeschrägtem Innenrand / versehenen Hülse α und dem Endflansch A der Rohrverbindung sitzt der Dichtungsring e von keilförmigem Querschnitt und wird beim Festschrauben der Rohrverbindung mittels der auf dem Schraubbolzen d sitzenden Muttern c zusammengepreßt. Die Keilspitze ψ des Dichtungsringes ist geschlitzt, und die so gebildeten Lippen legen sich fest gegen das Rohrende g bzw. gegen den abgeschrägten Innenrand/ der Hülse α und bilden eine zusätzliche Lippendichtung. An den dem durch die Rohrverbindung strömenden Medium ausgesetzten Stellen sind die Lippen des Dichtungsringes mit einer Bewehrung s aus Metall versehen.Between the beveled inner edge / provided sleeve α and the end flange A of the pipe connection, the sealing ring e sits with a wedge-shaped cross-section and is pressed together when the pipe connection is screwed on by means of the nuts c sitting on the screw bolt d. The wedge tip ψ of the sealing ring is slotted, and the lips formed in this way lie firmly against the pipe end g or against the beveled inner edge / the sleeve α and form an additional lip seal. At the points exposed to the medium flowing through the pipe connection, the lips of the sealing ring are provided with metal reinforcement s.
