Description
Die
vorliegende Erfindung betrifft eine Verbindung eines Rohres mit
einem Stutzen nach dem Oberbegriff des Anspruch 1. Eine derartige
Verbindung ist als zweites Ausführungsbeispiel
der
Nachteilig bei der vorbekannten Verbindung ist, dass das Rohr prinzipbedingt auf den Stutzen aufgeschoben und dabei radial gedehnt wird. Der Dehnvorgang führt gerade bei der Verwendung von Metallrohren zu erhöhten Montagekräften oder macht eine Erwärmung der Rohrenden vor der Montage erforderlich. Praktisch ist die Verwendung dieser Verbindung auf Kunststoffrohre beschränkt. Desweiteren kann das Dichtelement, welches in die Kammer des Stutzens eingelegt ist, beim Aufschieben des Rohres in Aufschieberichtung verdrillt oder sogar über die Außenkante der Kammer in den Spalt zwischen Rohr und Stützen extrudiert werden. Beides führt zu einer Beschädigung des Dichtelements führen.adversely with the previously known connection, the pipe is inherent to the principle is pushed onto the nozzle and thereby radially stretched. The Stretching process especially when using metal pipes to increased assembly forces or makes a warming the pipe ends required before assembly. The use is practical this connection is limited to plastic pipes. Furthermore, the sealing element, which is inserted into the chamber of the nozzle when sliding on of the pipe twisted in the push-on direction or even over the outer edge the chamber can be extruded into the gap between the tube and supports. Both leads to damage of the sealing element.
Aufgabe der vorliegenden Erfindung ist es daher, eine Verbindung anzugeben, die unter Aufwendung von geringen Kräften geschlossen werden kann und dessen Dichtelement nicht Gefahr läuft, bei der Montage beschädigt zu werden.task the present invention is therefore to provide a connection which can be closed with the application of low forces and its sealing element does not run the risk of being damaged during assembly become.
Gelöst wird diese Aufgabe durch eine Verbindung gemäß Anspruch 1.Is solved this task by a connection according to claim 1.
Eine grundlegende Idee der vorliegenden Erfindung besteht darin, das Rohr unverformt in den Stutzen einzustecken und erst durch Aufschieben des Ringes auf den Stutzen beide Teile so zu verformen, dass die gewünschte Festigkeit und Dichtheit der Verbindung entsteht. Verformt wird die Verbindung an zwei Stellen, nämlich im Bereich der Kammer und vorzugsweise endseitig. Durch das Aufschieben des Ringes auf den Stutzen erfährt die Kammer eine definierte Verformung, welche das Dichtelement in der Weise komprimiert, dass es die bestmögliche Dichtwirkung erzielt. Überhöhte Spannungen, die insbesondere Weichdichtungen beschädigen können, werden hierdurch wirksam vermieden.A basic idea of the present invention is that Insert the pipe into the socket undeformed and only by sliding the Ring on the neck to deform both parts so that the desired strength and tightness of the connection arises. The connection is deformed in two places, namely in the area of the chamber and preferably at the end. By postponing it of the ring on the nozzle the chamber a defined deformation, which the sealing element in compressed in such a way that it achieves the best possible sealing effect. Excessive tensions, This can damage soft seals in particular avoided.
Die vorteilhafte Weiterbildung der Erfindung besteht darin, die Kammer und das eingelegte Dichtelement dergestalt zu dimensionieren, dass das Dichtelement allein bei in den Stutzen eingestecktem Rohr nicht an dem Rohr anliegt. Das Dichtelement soll vielmehr erst durch Aufschieben des Ringes gegen das Rohr gepresst werden. Der entscheidende Vorteil dieser Weiterbildung besteht darin, dass das Dichtelement beim Einstecken des Rohres nicht verdrillt werden kann. Eine Beschädigung des Dichtelementes bei der Montage ist durch diese Maßnahme fast ausgeschlossen.The advantageous development of the invention is the chamber and dimension the inserted sealing element in such a way that the sealing element alone when the pipe is inserted into the socket abuts the pipe. Rather, the sealing element should only be pushed on of the ring are pressed against the pipe. The decisive advantage this development consists in the fact that the sealing element when inserted of the pipe cannot be twisted. Damage to the Sealing element during assembly is almost this measure locked out.
Vorteilhafterweise wird der Stutzen mit einer Anlageschulter versehen. Diese dient dazu, von einem zangenartigen Montagewerkzeug gegriffen zu werden, mittels welchem der Ring auf den Stutzen aufgeschoben wird. Derartige Montagewerkzeuge sind an sich bekannt, sie gleichen einer Zange, bei denen eine erste Wange an der Anlageschulter und eine weitere Wange an dem endseitigen Ringabschluss angreift.advantageously, the nozzle is provided with an abutment shoulder. This serves to be gripped by a plier-like assembly tool by means of which the ring is pushed onto the socket. such Assembly tools are known per se, they resemble pliers, where a first cheek on the contact shoulder and another Cheek engages the end of the ring.
Vorzugsweise ist die Anlageschulter mit einer Auflagefläche ausgestattet, auf welcher der Ring bei geschlossener Verbindung mit einem dritten zylindrischen Bereich aufliegt. Der Ring erhält hierdurch einen besonders sicheren Sitz. Desweiteren kann die Wange, mit welcher das Montagewerkzeug an der Montageschulter anliegt, zugleich als Anschlag für den aufzuschiebenden Ring dienen.Preferably the contact shoulder is equipped with a contact surface on which the ring when connected to a third cylindrical Area rests. The ring receives this ensures a particularly secure fit. Furthermore, the cheek, with which the assembly tool rests on the assembly shoulder at the same time as a stop for serve the ring to be pushed open.
Der Durchmesser des zweiten zylindrischen Abschnitts sollte so bemessen sein, dass er das Rohr mehr als 0,2% radial einschnürt. Für Stahlrohre bedeutet eine Stauchung von 0,2% eine plastische Verformung, durch welche die Verbindung teilweise formschlüssig und daher besonders stabil wird.The The diameter of the second cylindrical section should be dimensioned in this way be that it constricts the tube radially more than 0.2%. For steel pipes means a compression of 0.2% means plastic deformation which the connection is partially form-fitting and therefore particularly stable becomes.
Als Dichtelement eignet sich insbesondere ein Runddichtring (O-Ring). Runddichtringe haben sich als Standard-Industriedichtungen etabliert und sind in vielfältigen Durchmessern und Werkstoffen kostengünstig verfügbar.As A sealing element (O-ring) is particularly suitable for the sealing element. O-rings have established themselves as standard industrial seals and are in diverse Diameters and materials available at low cost.
Vorzugsweise erhält die Kammer die Gestalt eines Rotationskörpers, dessen Rotationsachse der Längsachse der Verbindung entspricht und deren Rotationsfläche ein Halbkreis ist. Eine derartige (Rund-)Kammer eignet sich insbesondere zur Aufnahme eines Runddichtringes. Ebenso können Kammern mit rechteckigem Querschnitt (Rechteckkammern) vorgesehen werden, in die ebenfalls Runddichtringe oder andere Arten von Dichtelementen Platz finden.Preferably receives the chamber the shape of a body of revolution, its axis of rotation the longitudinal axis corresponds to the connection and whose surface of revolution is a semicircle. A (round) chamber of this type is particularly suitable for accommodating one O-ring. You can also Chambers with a rectangular cross section (rectangular chambers) are provided be placed in the round sealing rings or other types of sealing elements Find.
