Abstract
Description
Die Erfindung betrifft eine Anordnung zum Verbinden des Endes eines schraubenlinienförmig gewellten Metallrohres mit einem Anschlußstück.The The invention relates to an arrangement for connecting the end of a helically corrugated Metal tube with a fitting.
Aus
der
Zwischen dem Druckring, dem Ende des Anschlußstücks und dem aus dem Druckring herausragenden Ende des gewellten Rohres ist eine Kammer gebildet, in welcher eine Dichtung aus Graphit vorgesehen ist, die beim längsaxialen Verspannen des Druckrings und des Anschlußstücks mittels Schraubbolzen in radialer Richtung verformt wird und das Ende des gewellten Rohres gegenüber dem Anschlußstück abdichtet.Between the pressure ring, the end of the fitting and the pressure ring protruding end of the corrugated tube is formed a chamber in which a seal made of graphite is provided, the longitudinal axial Bracing the pressure ring and the connecting piece by means of bolts in Radial direction is deformed and the end of the corrugated tube across from the connecting piece seals.
Eine Weiterbildung dieser Anordnung ist aus der DE-U-20 2004 007 321 bekannt, bei welcher ein Dichtungsring aus Graphit eingesetzt wird, der eine innere der Form der Wellung des Metallrohres angepaßte Profilierung aufweist und somit auf das Ende des Wellrohres aufgeschraubt werden kann.A Further development of this arrangement is known from DE-U-20 2004 007 321 known, in which a sealing ring made of graphite is used, the one adapted to the shape of the corrugation of the metal tube profiling and thus be screwed onto the end of the corrugated tube can.
Aus der JP 2001-082646 ist eine Anordnung der eingangs erwähnten Art bekannt, bei der ein Dichtring aus Gummi eingesetzt wird, welcher in radialer Richtung durchtrennt ist und von der Seite her auf das gewellte Rohr in ein Wellental eingelegt werden kann.Out JP 2001-082646 is an arrangement of the type mentioned in the opening paragraph known, in which a rubber sealing ring is used, which is severed in the radial direction and from the side to the corrugated pipe can be inserted into a trough.

Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung der eingangs erwähnten Art bereitzustellen, welche leicht zu montieren ist und ohne großen Kraftaufwand eine Abdichtung zwischen dem Wellrohr und dem Anschlußstück ermöglicht, welche einen Druck von mehr als 25 bar dauerhaft standhält. Insbesondere soll die Anordnung auch bei einem Gasdruck von mehr als 25 bar einsetzbar sein.Of the Invention is based on the object, an arrangement of the above mentioned To provide kind, which is easy to assemble and without much effort allows a seal between the corrugated tube and the fitting, which permanently withstands a pressure of more than 25 bar. Especially the arrangement should also be used at a gas pressure of more than 25 bar be.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.These The object is solved by the features of claim 1.
