Übergangsstück zum Verbinden von Kunststoffrohren mit Armaturen aus metallischen WerkstoffenTransition piece for connecting plastic pipes with fittings made of metallic materials
Die Neuerung betrifft ein Übergangsstück zum Verbinden von Kunststoffrohren für flüssige Medien mit Armaturen aus metallischen Werkstoffen, insbesondere im Sanitär- und Heizungsbereich, wobei das eine Ende des Übergangsstücks eine Bohrung zum Einschweißen des Kunststoffrohres und das andere Ende des Übergangsstücks eine eingespritzte metallene Anschlußhülse mit einem Gewinde zum Auf- bzw. Einschrauben der Armatur aufweist und wobei die metallene Anschlußhülse mit einer Verdrehsicherung in bezug auf einen die Anschlußhülse umgebenden Kunststoffkörper versehen ist, die aus in dem stirnseitigen inneren Ende der Anschlußhülse angebrachten Vertiefungen in Form von Schlitzen, Bohrungen u.dgl. besteht, in die der aufgespritzte Kunststoff eindringt und wobei ferner auf der zylindrischen äußeren Oberfläche der metallenen Anschlußhülse Ringnuten ausgebildet sind, in die der aufgespritzte Kunststoff ebenfalls eindringt.The innovation relates to a transition piece for connecting plastic pipes for liquid media with fittings made of metallic materials, in particular in the sanitary and heating sector, wherein one end of the transition piece has a hole for welding in the plastic pipe and the other end of the transition piece has an injected metal connection sleeve with a thread for screwing on or in the fitting, and wherein the metal connection sleeve is provided with an anti-twist device in relation to a plastic body surrounding the connection sleeve, which consists of recesses in the form of slots, holes and the like in the front inner end of the connection sleeve, into which the injected plastic penetrates, and wherein annular grooves are also formed on the cylindrical outer surface of the metal connection sleeve, into which the injected plastic also penetrates.
Derartige Übergangsstücke sind als Unterputzmuffen bekannt, wobei die Anschlußhülsen aus Metall, insbesondere Messing bestehen, und auf ihrer äußeren zylindrischen Oberfläche, die mit Kunststoff umspritzt wird, mehrere Ringnuten aufweisen zu dem Zweck, dieSuch transition pieces are known as flush-mounted sleeves, whereby the connecting sleeves are made of metal, in particular brass, and have several annular grooves on their outer cylindrical surface, which is coated with plastic, for the purpose of
Anschlußhülse in der aufgespritzten Kunststoffmasse
zu verankern (DE-GM 88 10 285.8).Connection sleeve in the sprayed plastic compound
to be anchored (DE-GM 88 10 285.8).
Es hat sich nun aber gezeigt, daß die Verankerung der auf die Anschlußhülsenoberfläche aufgespritzten
Kunststoffmasse in den Ringnuten bzw. die feste Verbindung zwischen dem Kunststoffmaterial und der
metallenen Oberfläche der Anschlußhülse in diesem
Bereich insofern zu wünschen übrig lässt, als aufgrund der bei der Verfestigung des Kunststoffmaterials auftretenden
Schrumpfspannungen das Kunststoffmaterial
nicht verhindert, daß zwischen ihm und der Oberfläche der Anschlußhülse das flüssige Transportmedium, also
beispielsweise Wasser, eindringt und im Laufe der
Zeit seinen Weg nach außen findet und dadurch das
Übergangsstück undicht macht. Da solche Übergangsstücke gewöhnlich unter Putz liegen, haben derartige
Undichtigkeiten Mauerwerksdurchfeuchtungen und damit erhebliche Schaden zur Folge.However, it has now been shown that the anchoring of the sprayed-on connection sleeve surface
Plastic mass in the ring grooves or the firm connection between the plastic material and the
metal surface of the connection sleeve in this
area leaves much to be desired in that due to the shrinkage stresses that occur during the solidification of the plastic material, the plastic material
does not prevent the liquid transport medium, such as water, from penetrating between it and the surface of the connection sleeve and, in the course of
Time finds its way out and thereby the
Transition piece becomes leaky. Since such transition pieces are usually located under plaster, such leaks result in moisture penetrating the masonry and thus causing considerable damage.
Zur Vermeidung dieses Nachteils schlägt die Neuerung vor, die Anschlußhülse so auszubilden, daß die Ringnuten
einen V-förmigen Querschnitt aufweisen.
Dieser Querschnitt macht die Ringnuten zu konischen Rillen mit der Folge,daß die beim Schrumpfen des aufgespritzten
Kunststoffmaterials in diesem auftretenden Spannungen dort, wo das Material vergleichsweise dünn
ist, nämlich am Fuße jeder konischen Rille, geringer sind als an Stellen größerer Materialdicke, wodurch
wiederum das Ablösen des Kunststoffmaterials von der metallenen Oberfläche der Anschlußhülse im Bereich
des Rillenfußes oder -bodens im wesentlichen vermieden wird, das Kunststoffmaterial also fest auf der
metallenen Oberfläche haften bleibt und damit die beimTo avoid this disadvantage, the innovation proposes to design the connecting sleeve in such a way that the annular grooves have a V-shaped cross-section.
This cross-section turns the ring grooves into conical grooves, with the result that the stresses occurring during shrinkage of the injected plastic material are lower where the material is comparatively thin, namely at the foot of each conical groove, than at places with greater material thickness, whereby
again the detachment of the plastic material from the metal surface of the connection sleeve in the area
of the groove foot or bottom is essentially avoided, so the plastic material is firmly attached to the
metal surface and thus the
Stande der Technik auftretenden Undichtigkeiten mit Sicherheit vermieden werden. Das Transportmittel, also beispielsweise Wasser, kann nun nicht mehr beim Durchströmen des Durchflußquerschnittes der Anschlußhülse in Art eines Kriechstroms zwischen das aufgespritzte Kunststoffmaterial fließen und damit seinen Weg über die herkömmliche Rignuten hinweg nach außen finden und auf diese Weise die Umgebung durchfeuchten.Leaks that occur with the current technology can be avoided with certainty. The transport medium, for example water, can no longer flow through the flow cross-section of the connecting sleeve in the form of a leakage current between the sprayed-on plastic material and thus find its way out through the conventional grooves and thus moisten the surrounding area.
Bei einer besonders vorteilhaften Ausführungsform des neuerungsgemäßen Übergangsstücks beträgt der öffnungswinkel des V-förmigen Querschnitts der Ringnuten ca. 55° bei einer Nutentiefe von ca. 1,2 mm und einem Abstand der aufeinanderfolgenden Nuten von ca. 2 mm. In diesem Zusammenhang hat sich auch bewährt, die Oberfläche der metallenen Anschlußhülse durchgehend zu vernickeln, beispielsweise mit einem Durnicoat genannten Material.In a particularly advantageous embodiment of the innovation-based transition piece, the opening angle of the V-shaped cross section of the ring grooves is approx. 55° with a groove depth of approx. 1.2 mm and a distance between the successive grooves of approx. 2 mm. In this context, it has also proven useful to nickel-plate the surface of the metal connection sleeve throughout, for example with a material called Durnicoat.
Die Neuerung wird im folgenden anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen:The innovation is explained in more detail below using the example shown in the drawing. The drawing shows:

Fig. 3 einen vergrößerten Ausschnitt der Ansicht von Fig. 2.Fig. 3 is an enlarged detail of the view of Fig. 2.
Die in den Zeichnungsfiguren dargestellte metallene Anschlußhülse 1 besitzt eine durchgehende vernickelte Oberfläche 8 und ist Bestandteil eines Übergangsstücks 9. Zu diesem Zweck ist ihre äußere Oberfläche mit einem thermoplastischen Kunststoff 4, beispielsweise einem Polyetherketon, ummantelt, der in der Zeichnung durch eine punktierte Fläche dargestellt ist und auf die Oberfläche 8 aufgespritzt wird. Diese Oberfläche ist zwischen den beiden stirnseitigen Enden 2, 3 der Anschlußhülse auf dem zylindrischen Außenumfang mit Ringnuten 7 versehen, die eine Reihe aufeinanderfolgender paralleler konischer Rillen bilden. Der öffnungswinkel des V-förmigen Querschnitts dieser Rillen oder Nuten beträgt ca. 55°, die Nuttiefe ca. 1,2 mm und der Abstand der aufeinanderfolgenden Nuten ca. 2 mm.The metal connection sleeve 1 shown in the drawings has a continuous nickel-plated surface 8 and is part of a transition piece 9. For this purpose, its outer surface is coated with a thermoplastic 4, for example a polyether ketone, which is shown in the drawing by a dotted area and is sprayed onto the surface 8. This surface is provided with annular grooves 7 on the cylindrical outer circumference between the two front ends 2, 3 of the connection sleeve, which form a series of consecutive parallel conical grooves. The opening angle of the V-shaped cross section of these grooves or grooves is approximately 55°, the groove depth is approximately 1.2 mm and the distance between the consecutive grooves is approximately 2 mm.
Desweiteren weist das hintere stirnseitige Ende mehrere parallele Schlitze 5 auf sowie eine Bohrung zum Einschweißen eines Kunststoffrohres, das mit Hilfe des Übergangsstücks an eine Armatur aus metallischen Werkstoffen angeschlossen werden soll, die durch das vordere stirnseitige Ende 2 der Anschlußhülse hindurch in eine mit einem Gewinde versehene Bohrung 10 eingeschraubt wird.Furthermore, the rear end face has several parallel slots 5 and a hole for welding in a plastic pipe, which is to be connected to a fitting made of metallic materials using the transition piece, which is screwed through the front end face 2 of the connection sleeve into a threaded hole 10.
Das Kunststoffmaterial 4 dringt beim Aufspritzen auf die Oberfläche des Anschlußstücks sowohl in die konischen Rillen oder Nuten 7 ein als auch in die stirnseitigen Schlitze 5, um die Anschlußhülse aufWhen sprayed onto the surface of the connector, the plastic material 4 penetrates both into the conical grooves or slots 7 and into the front slots 5 in order to hold the connector sleeve on

diese Weise in dem Kunststoffmaterial dicht und verdrehungssicher zu verankern. Die Tatsache, daß die äußere zylindrische Oberfläche 8 der Anschlußhülse mit den konischen Rillen 7 V-förmigen Querschnitts versehen ist, bewirkt, daß sich das Kunststoffmaterial, das nach dem Aufspritzen auf die Oberfläche schrumpft, nicht von der Oberfläche löst, da die Schrumpfspannungen am Rillenboden vergleichsweise gering sind, so daß das aufgespritzte Material auf der Oberfläche kleben bleibt und damit verhindert, daß Flüssigkeiten, die die Bohrung des Übergangsstücks durchströmen, auf der äußeren Oberfläche der Anschlußhülse entlangkriechen und damit das Übergangsstück undicht machen.in this way to anchor it tightly and securely in the plastic material. The fact that the outer cylindrical surface 8 of the connecting sleeve is provided with the conical grooves 7 with a V-shaped cross-section means that the plastic material, which shrinks after being sprayed onto the surface, does not detach from the surface, since the shrinkage stresses at the bottom of the groove are comparatively low, so that the sprayed material sticks to the surface and thus prevents liquids flowing through the bore of the transition piece from creeping along the outer surface of the connecting sleeve and thus making the transition piece leaky.
