PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Rohrverbindung mit für die Stützung der Leitungsrohre dienenden Fortsatzrohren und eingelassener Bleidichtung. Die bisher hauptsächlich im Bergbau gebräuchlichen Rohrverbindungen hatten den Nachteil, daß die Schwächung, die das Rohr durch das eingeschnittene Gewinde erfuhr, bei stark auftretendem Druck auf das Rohr einen Bruch gerade vor demThe invention relates to a pipe connection for supporting the conduit pipes serving extension tubes and embedded lead seal. The so far mainly in Pipe connections commonly used in mining had the disadvantage that the weakening, which the pipe experienced through the incised thread, under strong pressure on the pipe a break just before the

ίο Verbindungsstück bewirkte, so daß, abgesehen von den sonstigen Schäden, das Rohr herabfiel und eine Betriebsgefahr darstellte. Bei vorliegender Rohrverbindung schließen die Verbindungsstücke nicht mit dem innen das Gewinde für das Einschrauben des Rohrendes tragenden Rundteile ab, sondern sie setzen sich fort in glatte Rohre, deren innerer Durchmesser dem äußeren Durchmesser des einzuschraubenden Leitungsrohres entspricht.ίο connector caused so that, apart of the other damage that the pipe fell and posed an operational hazard. at With the existing pipe connection, the connecting pieces do not close with the inside Thread for screwing in the pipe end supporting round parts, but set them continues in smooth tubes, the inner diameter of which corresponds to the outer diameter of the corresponds to the pipe to be screwed in.

Diese Maßnahme bewirkt, daß der volle Querschnitt und nicht der geschwächte Gewindeteil des Rohres den auftretenden Druck aufnimmt, wodurch eine Bruchgefahr ausgeschlossen ist. Durch die zur Verwendung kommende bekannte ringförmige Bleidichtung wird ein Undichtwerden verhindert.This measure causes the full cross-section and not the weakened thread part of the pipe absorbs the pressure that occurs, eliminating the risk of breakage is. The known ring-shaped lead seal used is prevented from leaking.

Auf der Zeichnung ist die Rohrverbindung in Fig. ι bis 4 dargestellt.On the drawing, the pipe connection is shown in Fig. Ι to 4.

Sie besteht aus den beiden Gewindestücken α und b mit den Ansatzrohren c und d, in welche die Rohrenden eingeschraubt werden; ferner aus der in einer Ausdrehung des Gewindestückes b eingelassenen Bleidichtung e, auf die das Gewindestück α durch Anziehen der Überwurfsmutter f gepreßt wird.It consists of the two threaded pieces α and b with the extension pipes c and d, into which the pipe ends are screwed; also from the lead seal e embedded in a recess in the threaded piece b , onto which the threaded piece α is pressed by tightening the union nut f.
