Description

Es sind Rohrverbindungen mittels durch eine Oberwurfmutter angezogene Flanschen bekannt, von denen der eine auf der Dichtfläche mit einem oder mehreren ringförmigen, schneidenförmigen Ansätzen versehen ist. Auch die vorliegende Erfindung betrifft eine Rohrverbindung, bei der der eine Flansch mit einem oder mehreren ringförmigen Ansätzen versehen ist, jedoch besteht die Erfindung darin,There are pipe connections by means of an upper nut tightened flanges known, one of which on the sealing surface is provided with one or more annular, blade-shaped approaches. Even The present invention relates to a pipe connection in which a flange with a or several annular lugs is provided, but the invention consists in

ίο daß der oder die ringförmigen Ansätze auf den kegelförmig ineinanderpassenden Flanschen außen zylindrisch und innen kegelförmig begrenzt sind, so daß die härteren Ansätze das weichere Material des Gegenflansches aufschälen und eine Anreicherung des weicheren Materials in der inneren rinnenartigen Vertiefung des oder der Ansätze herbeiführen. ίο that the ring-shaped approach or approaches the conically fitting flanges are cylindrical on the outside and conical on the inside are limited, so that the harder approaches the softer material of the mating flange peel and an accumulation of the softer material in the inner gutter-like Bring deepening of the approach (s).

Dadurch wird erreicht, daß die ganze Masse der Rille nach innen, also die ganz zu verlagernde Masse an die für Bildung einer Dichtungsfläche günstigste Seite verlegt wird und die Dichtungsfläche etwa doppelt so groß wird wie bei den bekannten Rohrverbindun-This ensures that the whole mass of the groove goes inwards, that is to say that it closes completely shifting mass is laid on the side that is most favorable for the formation of a sealing surface and the sealing surface is about twice as large as with the known pipe connections

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. Es zeigen: Abb. 1 einen senkrechten Schnitt durch eine Verbindung, Abb. 2 eine Draufsieht auf den Dichtkonus und Abb. 3 die Dichtflächen der beiden abzudichtenden Enden in vergrößertem Maßstab.The subject of the invention is shown in the drawing, for example. It show: Fig. 1 a vertical section through a connection, Fig. 2 a top view on the sealing cone and Fig. 3 the sealing surfaces of the two to be sealed Ends on an enlarged scale.

Das anzuschließende Rohrende 1 wird zweckmäßig kegelförmig aufgeweitet. Das kegelförmige Formstück 2 erhält mehrere, z. B. drei bis vier konzentrisch übereinander angeordnete ringförmige Ansatzes 4, deren Höhe ungefähr 1Z2'bis 2/3mm beträgt, so daß diese Ansätze eine Rohrwandstärke von etwa ι mm nicht durchschneiden können. Die Ansätze 4 sind "schneidenförmig so ausgebildet, daß sie außen zylindrisch und innen kegelförmig begrenzt sind. Das Formstück 2 besteht aus härterem Material, so daß beim Zusammenspannen der Flanschen die härteren Ansätze 4 mit ihrer Schneide das weichere Material des Gegenflansches auf schälen und eine Anreicherung des weicheren Materials in der inneren rinnenartigen Vertiefung 3 des oder der Ansätze herbeiführen. Dadurch werden Unebenheiten der Dichtfläche 5 ausgefüllt und eine vollkommene Dichtung zwischen den zu verbindenden Flanschen ohne allzu großes Anspannen der Überwurfmutter 6 erreicht.The pipe end 1 to be connected is expediently widened conically. The conical fitting 2 receives several, for. B. three to four concentrically superposed annular extension 4, the height of which is approximately 1 Z 2 'to 2/3 mm , so that these approaches can not cut through a pipe wall thickness of about ι mm. The lugs 4 are "blade-shaped so that they are cylindrical on the outside and conical on the inside. The shaped piece 2 consists of a harder material, so that when the flanges are clamped together, the harder lugs 4 peel the softer material of the counter flange with their cutting edge and create an enrichment of the softer material in the inner channel-like recess 3 of the lug (s), thereby filling unevenness in the sealing surface 5 and achieving a perfect seal between the flanges to be connected without overly tightening the union nut 6.
