Description

Rohrverbindungsmuffe Die Erfindung betrifft eine Rohrverbindungsmuffe aus thermoplastischem, verhältnismäßig hartem Kunststoff mit einer zylindrischen oder schwach kegelförmigen Innenwandung, die zur Verbindung von aus ebensolchem Kunststoff bestehenden Rohren mit deren einander zugekehrten Enden unter Radialspannung fest durch Verschweißen oder Verkleben verbunden ist. Rohrverbindungsmuffen aus thermoplastischem und verhältnismäßig hartem Kunststoff bestehen nicht aus jenen Kunststoffen mit einer gummielastischen Schläuchen ähnlichen Flexibilität.Pipe connection socket The invention relates to a pipe connection socket made of thermoplastic, relatively hard plastic with a cylindrical or slightly conical inner wall, which is used to connect from the same Existing plastic pipes with their ends facing each other under radial tension is firmly connected by welding or gluing. Pipe connection sleeves thermoplastic and relatively hard plastic do not consist of those Plastics with a flexibility similar to rubber-elastic tubes.

Unter dieser Werkstoffangabe werden vielmehr Kunststoffe verstanden, wie sie dort verwendet werden, wo ein Erwärmen der Muffe und des Rohres für die Montage vorgenommen wird, woraus sich ergibt, daß die Rohre von der Muffe mit Radialspannung umgeben sind.Rather, this material specification refers to plastics, how they are used where there is a heating of the sleeve and the pipe for the Assembly is carried out, from which it follows that the pipes from the socket with radial tension are surrounded.

Es hat sich nun gezeigt, daß, wenn derartige Rohrverbindungsmuffen innerem Druck ausgesetzt sind, im Laufe der Zeit als Folge der Bildung von durch Kerbwirkung entstehenden Haarrissen, welche von der Stelle ausgehen, wo die Haftung zwischen dem Rohr oder den Rohren und der Rohrverbindungsmuffe endet, und die in unregelmäßiger Weise durch die Wandung der Muffe hindurch verlaufen, Undichtigkeiten auftreten. It has now been shown that when such pipe connecting sleeves are exposed to internal pressures over time as a result of the formation of by Notch effect resulting hairline cracks, which start from the point where the adhesion between the pipe or pipes and the pipe connecting sleeve ends, and the in run irregularly through the wall of the sleeve, leaks appear.

Es ist bereits bekannt, Rohrverbindungsmuffen dadurch zu verstärken, daß in die Muffe eine Verstärkungseinlage eingearbeitet wird. Es zeigt sich aber, daß hierdurch die durch die Haarrisse bedingten Undichtigkeiten nicht beseitigt werden können. It is already known to reinforce pipe connection sleeves by that a reinforcing insert is incorporated into the sleeve. But it shows that this does not eliminate the leaks caused by the hairline cracks can be.

An Rohrverbindungsmuffen ist es auch nicht neu, einen ringförmigen Kanal im Muffenkörper vorzusehen, dessen Abmessung in axialer Richtung wenigstens gleich seinem Abstand von der Innenwandung der Muffe ist und der glatte und gerade Begrenzungsflächen aufweist. Diese Maßnahme ist jedoch an Rohrverbindungsmuffen verwirklicht worden, welche aus elastischem Werkstoff bestehen, so daß hier zusammen mit dem vorgesehenen Reibungsschluß zwischen Muffeninnenmantel und Rohroberfläche ein mit Haarrissen zusammenhängendes Abdichtproblem nicht auftritt. It is also not new to pipe connection sleeves, a ring-shaped one Provide channel in the sleeve body, its dimension in the axial direction at least is equal to its distance from the inner wall of the sleeve and is smooth and straight Has boundary surfaces. However, this measure is applicable to pipe connection sleeves been realized, which consist of elastic material, so that here together with the intended frictional connection between the inner sleeve jacket and the pipe surface a sealing problem associated with hairline cracks does not occur.

Die Erfindung hat sich die Aufgabe gestellt, eine Rohrverbindungsmuffe der eingangs erläuterten Art so zu verbessern, daß es beim Auftreten von Haarrissen nicht mehr zu einer Undichtigkeit der durch sie geschaffenen Verbindung kommen kann. The invention has the task of providing a pipe connection socket to improve the type explained above so that it occurs when hairline cracks can no longer lead to a leak in the connection created by them.

Diese Aufgabe löst die Erfindung dadurch, daß zur Begrenzung von von den mit der Muffe verklebten oder verschweißten Rohrenden ausgehenden Haarrissen in den Muffenkörper ein an sich bekannter ringförmiger Kanal, dessen Abmessung in axialer Richtung wenigstens gleich seinem Abstand von der Innenwandung der Muffe ist und der glatte und gerundete Begrenzungsflächen aufweist, gebildet ist. This object is achieved by the invention in that to limit hairline cracks emanating from the pipe ends glued or welded to the socket in the socket body a known per se annular channel, the dimensions of which in axial direction at least equal to its distance from the inner wall of the sleeve and which has smooth and rounded boundary surfaces is formed.

Dieser Kanal hat die überraschende Eigenschaft, daß bei einer von vornherein durch Kleben oder Verschweißen hergestellten dichten Verbindung bei der aus verhältnismäßig hartem Kunststoff bestehenden Rohrverbindungsmuffe etwa auftretende Haarrisse aufgehalten werden und sich demzufolge nicht durch den ganzen Muffenkörper nach außen fortsetzen können. Dadurch wird die Bildung von durchgehenden Verbindungen aus dem Inneren der Rohrverbindungsmuffe nach außen und damit ein Undichtwerden der Verbindung vermieden. This channel has the surprising property that with one of the tight connection produced in advance by gluing or welding from relatively hard plastic existing pipe connection sleeve about occurring Hairline cracks are held up and consequently not through the entire socket body can continue to the outside. This enables the formation of continuous connections from the inside of the pipe connection socket to the outside and thus a leak the connection avoided.

Gemäß einem weiteren Merkmal der Erfindung kann der ringförmige Kanal ganz oder teilweise durch einen Körper aus härterem Werkstoff als dem der Muffe ausgefüllt werden. Dabei kann es sich um einen Körper aus Metall, einem keramischen Werkstoff oder einem wärmehärtbaren Kunststoff handeln. Von diesem Merkmal wird vorzugsweise dann Gebrauch gemacht, wenn die Muffe durch Spritzguß oder durch Schleuderguß hergestellt wird. Falls dieser Körper im übrigen auf den ganzen Umfang oder örtlich nach einwärts vorspringt, kann er zugleich einen Anschlag für das oder die zu kuppelnden Rohre bilden. According to a further feature of the invention, the annular channel in whole or in part by a body made of a harder material than that of the socket fill out. It can be a body made of metal, a ceramic one Act material or a thermosetting plastic. From this characteristic will preferably used when the sleeve is injection molded or centrifugally molded will be produced. If this body is otherwise on the whole circumference or locally protrudes inwards, it can at the same time be a stop for the one or those to be coupled Form tubes.

Nachstehend wird die Erfindung näher an Hand der Zeichnung erläutert; es zeigen F i g. 1 und 2 in teilweisem Längsschnitt eine Rohrverbindung mit einer Rohrverbindungsmuffe bekannter Bauart und Fig. 3 und 4 in den Fig. 1 und 2 entsprechender Darstellung eine erfindungsgemäße Rohrverbindungsmuffe. The invention is explained in more detail with reference to the drawing; it show F i g. 1 and 2 in partial longitudinal section a pipe connection with a Pipe connection socket of known type and Figs. 3 and 4 in Figs. 1 and 2, a pipe connection sleeve according to the invention, corresponding to a representation.

Gemäß den Fig. 1 und 2 sind zwei Rohre 1 und 2 aus thermoplastischem Kunststoff mit Hilfe einer Rohrverbindungsmuffe 3, die in der Mitte ihrer Länge einen aus ihrer Innenfläche vorspringendenringförmigen Flansch 4 aufweist, miteinander verbunden. Die ebenfalls aus thermoplastischem Kunststoff bestehende Muffe 3 ist an ihrer Innenfläche 5 mit der Außenfläche 6 des Endes des Rohres 1, das bis an den Flansch 4 in die Muffe 3 hineinragt und mit seiner Endkante an diesen Flansch anstößt, verschweißt. In gleicher Weise ist die Innenfläche 7 des anderen Endes der Muffe 3 mit der Außenfläche des Endes des Rohres 2 verschweißt, welches bis an den Flansch 4 in die Muffe 3 hineinragt und mit seiner Endkante an diesen Flansch anstößt. According to FIGS. 1 and 2, two tubes 1 and 2 are made of thermoplastic Plastic with the help of a pipe connecting sleeve 3, which is in the middle of its length has an annular flange 4 projecting from its inner surface, with one another tied together. The sleeve 3, which is also made of thermoplastic material on its inner surface 5 with the outer surface 6 of the end of the tube 1, which is up to the flange 4 protrudes into the sleeve 3 and with its end edge on this flange abuts, welded. In the same way is the inner surface 7 of the other end the sleeve 3 is welded to the outer surface of the end of the pipe 2, which up on the flange 4 protrudes into the sleeve 3 and with its end edge on this flange bumps.

Wie Eig. 2 zeigt, entstehen bei dieser bekannten Rohrverbindungsmuffe unter dem Einfluß des Innendruckes im Laufe der Zeit Haarrisse, die von der Stelle ausgehen, an welcher die Haftung zwischen einem Rohr und der Muffe endet Der Verlauf eines solchen Haarrisses, der zu Undichtigkeiten Anlaß geben kann, ist in F i g. 2 bei 9 dargestellt. Like prop. 2 shows, arise in this known pipe connection sleeve under the influence of the internal pressure in the course of time hairline cracks from the place start at which the adhesion between a pipe and the socket ends The course such a hairline crack, which can give rise to leaks, is shown in FIG. 2 shown at 9.

Bei der in den F i g. 3 und 4 dargestellten- Ausführungsform der erfindungsgemäßen Rohrverbindungsmuffe ist diese ebenfalls aus thermoplastischem, verhältnismäßig - hårtem Kunststoff hergestellt. Diese Rohrverbindungsmuffe 10 weist einen ringförmigen Kanål 11 auf, dessen Abmessung in axialer Richtung wenigstens gleich seinem Abstand von der Innenwandung der Muffe ist und der glatte und gerundete Begrenzungsflächen aufweist. In the case of the FIGS. 3 and 4 illustrated embodiment of the pipe connection sleeve according to the invention, this is also made of thermoplastic, relatively - made of hard plastic. This pipe connection socket 10 has an annular channel 11, the dimension of which in the axial direction at least is equal to its distance from the inner wall of the sleeve and the smooth and rounded Has boundary surfaces.

Bei dem dargestellten Ausführungsbeispiel ist der ringförmige Kanal 11 mit einem gleichfalls ringförmigem Körperl2 aus härterem Werkstoff ausgefüllt. In the illustrated embodiment, the annular channel is 11 filled with a likewise annular body 12 made of a harder material.

Dieser Körper weist in der Mitte seiner Breite einen nach innen sich -erweiternden ringförmigen Flansch 13 von solcher Breite auf, daß- dieser Flansch sich bis über die Innenfläche der VerbindungsmuffelO erstreckt. Dieser Flansch 13 bildet derart einen Anschlag für die in die Muffe hineinragenden Enden der Rohre 1 und 2 aus thermoplastischem Kunststoff, der verhältnismäßig hart ist und dem Werkstoff der Rohrverbindungsmuffe entspricht.This body points inwards in the middle of its width -expanding annular flange 13 of such width that- this flange extends over the inner surface of the connecting muffle O. This flange 13 thus forms a stop for the ends of the protruding into the sleeve Tube 1 and 2 made of thermoplastic material, which is relatively hard and the material corresponds to the pipe connection socket.

Wie F i g. 4 zeigt, wird ein Haarriß 14, der an der Stelle entstehen kann, an welcher die Haftung zwischen beispielsweise dem Rohr 1 und der Muffe 10. endet, daran gehindert, sich weiter als bis zu der Innenwandung des ringförmigen Kanals 11 fortzusetzen. Hierdurch wird, wie ersichtlich, die Entstehung einer von innen nach außen durchgehenden Verbindung und folglich die Gefahr des Undichtwerdens der Rohrverbindung in wirksamer Weise vermieden. Like F i g. 4 shows, a hairline crack 14 will arise at the point can, on which the adhesion between, for example, the pipe 1 and the socket 10. ends, prevented from spreading further than up to the inner wall of the annular Channel 11 to continue. This, as can be seen, the emergence of one of inside to outside continuous connection and consequently the risk of leakage the pipe connection avoided in an effective manner.
