Description

Das Hauptpatent 643 472 hat eine Rohrkupplung für flanschenlose Rohre zum Gegenstand, bei der die Rohre durch von einer Überwurfmuffe getragene und -exzentrische Klemmkörper in die Überwurfmuffe hineingezogen werden,, wobei eine zwischen die Rohrenden einzulagernde Dichtung unter Pressung gesetzt wird. Eine solche Rohrverbindung ist starr und gewährt keine Beweglichkeit der Rohrenden im Sinne einer Winkelschwingung. Diese Winkelbewegung soll durch die Erfindung für Einrichtungen nach dem Hauptpatent möglich gemacht werden. Zu diesem Zwecke ist die Muffe in zwei Teile geteilt, und die Teile haben kugelig ausgestaltete Enden, mit denen sie sich übergreifen. So wie die Muffe ist auch die Dichtung in. zwei Teile geteilt. Der eine Teil ist fest in einem Muffenteil verlagert und steht unter Druck und Gegendruck zwischen dem einen Rohrende und dem einen Muffenteil. Der andere Teil der Dichtung liegt dagegen in der kugelig gestalteten Höhlung und wird von dem andern Rohrende mittels der Exzenter unter Druck genommen, derart, daß beide Muffenteile als Widerlager dienen, daß also Abdichtung zwischen beiden Muffenteilen erreicht wird.The main patent 643 472 relates to a pipe coupling for flangeless pipes in which the pipes are drawn into the coupling sleeve by clamping bodies carried and eccentric by a coupling sleeve, whereby a seal to be stored between the pipe ends is placed under pressure. Such a pipe connection is rigid and does not allow the pipe ends to move in the sense of an angular oscillation. This angular movement is to be made possible by the invention for devices according to the main patent. For this purpose, the sleeve is divided into two parts, and the parts have spherical ends with which they overlap. Like the sleeve , the seal is also divided into two parts. One part is firmly displaced in a socket part and is under pressure and counterpressure between one pipe end and one socket part. The other part of the seal, however, lies in the spherical cavity and is taken under pressure from the other end of the pipe by means of the eccentric so that both socket parts serve as an abutment, so that sealing between the two socket parts is achieved.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar teils in Ansicht, teils im Schnitt.In the drawing, the invention is shown in an embodiment shown, partly in view, partly in section.

Die Rohrenden α und α1 sind miteinander zu verbinden und abzudichten. Das geschieht durch eine __ Einsteckmuffe, die aus zwei Teilen b und b1 besteht. Beide Muffenteile greifen durch kugelig ausgebildete Enden ineinander, wobei das Ende e des Mufienteilesö als Hohlkugel und das Ende/ des Muffenteiles b1 ballig ausgebildet ist. Beide Muffenteile werden unter axialem Druck, nachdem sie erwärmt sind, ineinandergepneßt und sind nach Erkaltung nicht mehr voneinander zu trennen, da der eine vom andern übergriffen wird. ■ »The pipe ends α and α 1 are to be connected to one another and sealed. This is done with a __ socket, which consists of two parts b and b 1 . Both sleeve parts engage with one another through spherical ends, the end e of the sleeve part being formed as a hollow sphere and the end / of the sleeve part b 1 being spherical. Both sleeve parts are pressed into one another under axial pressure after they have been heated and can no longer be separated from one another after cooling, since one is overlapped by the other. ■ »

Die Exzenter C greifen wie beim Hauptpatent durch die Muffenwandungen hindurch und sind so eingerichtet, daß sie die Rohrenden iß und α1 beim Einschwenken gegeneinander, also zur Muffe einwärts, bewegen. Der Muffenteil b besitzt eine Dichtung d, die durch das Rohrenden gegen den Muffenteilb zur Anpressung gebracht wird. Es ist weiter eine Dichtung rf1 vorgesehen, die durch das Rohrende α1 zur Anpressung kommt, die aber dabei eine gesicherte Lage zwischen dem Rohrende«1 und dem Teil/ des Muffenteiles δ1 einerseits und dem Teile des Muffenteiles δ andererseits erhält. Dabei zwängt sich diese Dichtung^1 so in die kugelige Höhlung ein, daß sie Winkelbewegungen der Rohrteile a und ax untereinander folgen kann.As in the main patent, the eccentrics C reach through the socket walls and are set up in such a way that they move the pipe ends iß and α 1 against each other when they are pivoted, that is to say inwards towards the socket. The socket part b has a seal d which is pressed against the socket part b by the pipe ends. A seal rf 1 is also provided, which is pressed through the pipe end α 1 , but which is in a secure position between the pipe end « 1 and the part / socket part δ 1 on the one hand and the part of the socket part δ on the other. This seal ^ 1 wedges itself into the spherical cavity in such a way that it can follow the angular movements of the pipe parts a and a x with one another.
