Description

Der Anschluß zweier konzentrischer Rohre an zwei andere konzentrische Rohre von abweichendem Durchmesser mittels Verschraubungen unter Erhaltung des freien Durchflusses ist dadurch erschwert, daß die Verschraubung der inneren Rohre innerhalb der äußeren Rohre erfolgen muß. Die vorliegende Erfindung betrifft eine besondere Konstruktion zur Vereinfachung dieser Verbindung, die darin besteht, daß die inneren und äußeren Rohre durch je eine Stopfbüchsenpackung miteinander verbunden werden, die gleichzeitig durch eine Überwurfmutter angepreßt werden. Dies ist dadurch ermöglicht,The connection of two concentric pipes to two other concentric pipes of a different one Diameter by means of screw connections while maintaining free flow is made more difficult by the fact that the inner tubes must be screwed inside the outer tubes. The present The invention relates to a special construction to simplify this connection, which consists in that the inner and outer tubes each through a gland packing are connected to each other, which are pressed at the same time by a union nut will. This is made possible by

»5 daß die äußere Packung unmittelbar durch einen Druckring zusammengedrückt wird, während die Anpressung der inneren Packung durch ein zwischen der äußeren und inneren Packung liegendes, mit Durchflußöffnungeii versehenes Zwischenstück erfolgt.»5 that the outer packing is pressed together directly by a pressure ring, while the inner packing is pressed by a between the outer and inner Pack lying flat, with flow opening egg provided intermediate piece takes place.

Außer der äußerst einfachen Handhabung hat diese Anordnung den Vorteil, daß die innere Packung keine Überwurfmutter benötigt und somit der freie Querschnitt der Rohre weniger beengt wird. Es ist ferner ein unbemerktes Lösen der inneren Packung z. B. durch Rütteln o. dgl. ausgeschlossen.In addition to the extremely simple handling, this arrangement has the advantage that the inner packing does not require a union nut and thus the free cross-section of the Pipes are less cramped. There is also an unnoticed loosening of the inner pack z. B. excluded by shaking or the like.

In beiliegender Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Zeichnung stellt einen Mittelschnitt dar.An exemplary embodiment of the invention is shown in the accompanying drawing. the Drawing represents a middle section.

Es bedeuten A und D die äußeren, B und C die inneren konzentrischen Rohre, die miteinander zu verbinden sind. Die Verbindung der äußeren Rohre erfolgt durch die Packung G, die mittels des Druckringes J und der Überwurfmutter H angepreßt wird. Die untere Auflage der Packung G wird gebildet durch ein verschiebbares Zwischenstück E1 das so geformt ist, daß es zugleich als Druckring für die innere Packung F 4» dient. Das Zwischenstück E ist mit öffnungen K versehen, die den freien Durchfluß durch die äußeren Rohre gestatten. A and D denote the outer, B and C the inner concentric tubes which are to be connected to one another. The outer tubes are connected by the packing G, which is pressed on by means of the pressure ring J and the union nut H. The lower support of the pack G is formed by a displaceable intermediate piece E 1 which is shaped in such a way that it also serves as a pressure ring for the inner pack F 4 ». The intermediate piece E is provided with openings K which allow free flow through the outer tubes.
