Description
Die Erfindung betrifft eine Anschlußverbindung für Rohre durch Verschraubung, bei welcher eine Mutter auf der anzuschließenden Röhre frei drehbar angeordnet ist und über einenGewindeansatz der anderenRöhre-greift. Bei solchen Schraubverbindungen ist gewöhnlich eine der Röhren mit einem kegelförmigen Ansatz versehen, der in eine entsprechende Ausnehmung des anderen Rohres eingreift, wobei die beiden Teile durch die mit einem Bunde verseheneMutter, gegebenenfalls unter Zwischenlage eines Ringes, zusammengehalten werden. Diesen bekannten Verbindungen gegenüber bezweckt die Erfindung mit der geringsten Anzahl von Teilen, nämlich der üblichen Schrauibmutter, einem Beilagering und dementsprechend ausgebildeten Ende des Rohres selbst eine auch bei Ausführungsungenauigkeiten sich selbsttätig einstellende Verbindung zu schaffen. Erreicht wird dies dadurch, daß das Ende des anzuschließenden Rohres ohne Verengerung des Durchgangsquerschnittes derart kegelförmig aufgeweitet ist, daß der rückwärtige Teil der Aufweitung eine bundartige, senkrecht oder nahezu senkrecht zur Rohrachse liegende Auflagefläche für einen Beilagering bildet, der sich mit kugeliger Auflagefläche an die Überwurfmutter anlegt.The invention relates to a connection for pipes by screwing, at which a nut is freely rotatably arranged on the tube to be connected and over one thread lug of the other tube-engages. In such screw connections, one of the tubes is usually tapered Provided approach that engages in a corresponding recess of the other tube, the two parts through the collared nut, optionally under Interlayer of a ring to be held together. These known compounds against the aim of the invention with the least number of parts, namely the usual screw nut, a shim ring and a correspondingly designed end of the Rohres itself an automatically adjusting even in the case of inaccuracies in the execution To create connection. This is achieved by the fact that the end of the to be connected Tube widened in such a conical shape without narrowing the passage cross-section is that the rear part of the expansion is a collar-like, perpendicular or almost perpendicular to the pipe axis lying contact surface forms for a shim ring, which is with a spherical contact surface on the union nut applies.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Das Ende des anzuschließenden Kupferrohres α wird zuerst zylindrisch aufgeweitet und dann kegelförmig zusammengepreßt, um den kegeligen Ansatz b zu bilden, wobei zur Herstellung irgendwelche Werkzeuge verwendet werden. Vor oder nach der Herstellung des kegeligen Ansatzes wird ein Ring c über die Röhre geschoben. Die eine Seite d des Ringes (Abb. 4) ist flach und dient zur Auflage auf. der Schulter, die an dem Übergang des Ansatzes zum Hauptrohr gebildet wird, während die andere Fläche e kugelig gestaltet ist und an einem entsprechend kugelig ausgedrehten Ansatz g der Mutter / anliegt. Man erhält auf diese Weise eine sehr einfache und doch einstellungsfähige Verbindung, bei der durch Anwendung eines losen und frei drehbaren Beilageringes c ein Verschleiß des *an dem Rohr gebildeten Bundes auch bei häufigem Lösen der Verbindung behoben ist. Zweckmäßig ist es, diesen Beilagering aus anderem Material als die anliegenden Teile, z. B. aus Stahl, zu machen.The end of the copper pipe to be connected α is first expanded cylindrically and then pressed together in a conical shape to form the conical projection b , any tools being used for the production. Before or after the production of the conical extension, a ring c is pushed over the tube. One side d of the ring (Fig. 4) is flat and serves to rest on. the shoulder, which is formed at the transition from the extension to the main pipe, while the other surface e is designed spherically and rests against a correspondingly spherically turned extension g of the nut /. In this way, a very simple and yet adjustable connection is obtained, in which wear of the collar formed on the tube is eliminated even if the connection is frequently loosened by using a loose and freely rotatable shim ring c. It is useful to make this shim ring made of a different material than the adjacent parts, for. B. made of steel.
