Description

Rohrverbindung Die Erfindung bezieht sich auf eine Rohrverbindung für Rohre mit Endbunden mittels einer übergeschpbenen Muffe, die mit einem fest mit ihr verbundenen Ringvorsprung den Endbund des einen Rohres hintergreift, während sie am Endbund des anderen Rohres durch einen Sprengring lösbar abgestützt ist, der auf der ganzen axialen Länge sowohl seines in eine ringförmige Aussparung auf der Muffeninnenfläche als auch seines in eine Ringnut in der Endbundoberfläche eingreifenden Teils geführt ist.Pipe connection The invention relates to a pipe connection for pipes with end collars by means of a sleeve that is pushed over with a fixed with her connected ring projection engages behind the end collar of a tube while it is releasably supported by a snap ring on the end collar of the other pipe, which over the entire axial length of both its in an annular recess the sleeve inner surface as well as its engaging in an annular groove in the end collar surface Partly is led.

Bei einer bekannten Ausführungsform dieser Art weist der Sprengring ein radial überstehendes Ende auf, das durch eine relativ große öffnung herausragt und eine Lösung der Rohrverbindung erlaubt. Dies beeinträchtigt aber einerseits die Stabilität der Rohrverbindung, andererseits wird an dem Rohräußeren ein unerwünschter Vorsprung geschaffen. Sofern bei anderen, weiterhin bekannten Ausführungsformen ähnlicher Art der Sprengring keinen unerwünschten radialen Vorsprung schafft, ist ein radialer Abstand zwischen Rohr und Muffe erforderlich als Platz für die axial überstehenden Sprengringenden bzw. für ein in Axialnuten des Sprengrings eingreifenden Spezialwerkzeug, um die Verbindung zu lösen. Hierdurch wird eine unerwünscht große Radialausdehnung für die Verbindung geschaffen.In a known embodiment of this type, the snap ring a radially protruding end which protrudes through a relatively large opening and a loosening of the pipe connection is allowed. On the one hand, this has a negative impact the stability of the pipe joint, on the other hand, becomes an undesirable on the pipe exterior Creation of the lead. Unless in other, still known embodiments a similar type of snap ring does not create an undesirable radial protrusion a radial distance between pipe and socket is required as space for the axial protruding snap ring ends or for one engaging in axial grooves of the snap ring Special tool to loosen the connection. This results in an undesirably large Radial expansion created for the connection.

Diese Nachteile werden durch die Erfindung dadurch beseitigt, daß die Ringnut in der Endbundoberfläche und der darin geführte Teil des Sprengrings axial über das Ende der Muffe hinausragen. Die Bunde können als Vorschweißbunde ausgebildet sein. Zwecks Abdichtung der Rohrverbindung kann die Muffe mit Nuten ausgerüstet sein, die zur Aufnahme von O-Ring-Dichtungen dienen.These disadvantages are eliminated by the invention in that the annular groove in the end collar surface and the part of the snap ring guided therein axially protrude beyond the end of the sleeve. The collars can be used as pre-welded collars be trained. In order to seal the pipe connection, the socket can be provided with grooves be equipped, which are used to accommodate O-ring seals.

Die erfindungsgemäße Rohrverbindung kann an Rohren aller Art, z. B. an Stahlrohren ebenso wie an Kunststoffrohren, verwendet werden. Sie eignet sich für alle Systeme, die mit Durchflußmedien unter Drücken im Bereich von 0 bis 300 ata beschickt werden.The pipe connection according to the invention can be connected to pipes of all types, eg. B. on steel pipes as well as on plastic pipes. It is suitable for all systems that are charged with flow media at pressures in the range from 0 to 300 ata.

Eine beispielsweise Ausführungsform einer erfindungsgemäßen Rohrverbindung ist in der Zeichnung im Längsschnitt dargestellt. Die beiden Vorschweißbunde sind mit 1 und 2 bezeichnet. Der Vorschweißbund 1 ist auf der Endbundoberfläche mit einer Ringnut 3 versehen, in welcher ein Sprengring 4 eingelegt ist. Der Sprengring 4 besitzt einen zylindrischen, verstärkten Teil 5, der seinerseits in die ringförmige Aussparung 6 auf der Innenfläche der Muffe 7 eingreift. Die Muffe 7 hintergreift am anderen Ende mit einem fest mit ihr verbundenen Ringvorsprung den Endbund 10 des Vorschweißbundes 2. In der Muffe 7 können Nuten 8 vorhanden sein, in denen O-Ring-Dichtungen sitzen, die einen dichten Verschluß nach außen sichern. Zwecks Lösen der Verbindung wird der Sprengring 4 beispielsweise an der über das Ende der Muffe 7 axial überstehenden Stelle 11 radial eingezogen, was z. B. vermittels einer Schnur oder eines Drahtes erfolgen kann. Dadurch wird die kraftschlüssige Verriegelung zwischen dem verstärkten Teil 5 und der Aussparung 6 aufgehoben. Ein einfaches Verschieben der Muffe 7 in Rohrachsrichtung gestattet ein Herausnehmen des Rohres ohne Drehung oder axiale Verschiebung.An example embodiment of a pipe connection according to the invention is shown in the drawing in longitudinal section. The two welding necks are labeled 1 and 2. The welding neck 1 is provided on the end collar surface with an annular groove 3 in which a snap ring 4 is inserted. The snap ring 4 has a cylindrical, reinforced part 5 which in turn engages in the annular recess 6 on the inner surface of the sleeve 7. The sleeve 7 engages behind the end collar 10 of the welding collar 2 at the other end with an annular projection firmly connected to it. In the sleeve 7 , grooves 8 can be present in which O-ring seals sit, which secure a tight seal to the outside. To release the connection, the snap ring 4 is retracted radially, for example at the point 11 protruding axially beyond the end of the sleeve 7 , which z. B. can be done by means of a cord or wire. As a result, the positive locking between the reinforced part 5 and the recess 6 is canceled. A simple displacement of the sleeve 7 in the direction of the axis of the pipe allows the pipe to be removed without rotation or axial displacement.
