Anschlußabschnitt eines Kunststoffrohres sowie Verbindungsanordnung mit einem Anschlußabschnitt und einem Verbindungsabschnitt Connection section of a plastic pipe and connection arrangement with a connection section and a connecting section
BeschreibungDescription
Die Erfindung betrifft einen Anschlußabschnitt eines Kunststoffrohres, insbesondere eines aus einem Band aus einem thermoplastischen Kunststoff hergestellten Wickelrohres, zur Verbindung mit einem weiterem Kunststoffrohr aus thermoplastischen Kunststoff.The invention relates to a connecting section of a plastic pipe, in particular a wound pipe made from a strip of a thermoplastic material, for connection to another plastic pipe made of thermoplastic material.
Zum Verbinden von Kunststoffrohren werden diese in der Regel miteinander verschweißt. In der EP 0 535 247 Bl ist eine solche Schweißverbindung zwischen zwei Kunststoffrohren gezeigt. Ein erstes Rohr weist einen Anschlußabschnitt mit einer zylindrischen Anschlußbohrung auf, in die durch eine Öffnung der Bohrung ein Verbindungsabschnitt eines zweiten Kunststoffrohres einführbar ist. In die Innenfläche der Anschlußbohrung ist ein Widerstandsheizdraht eingelassen. Dieser verläuft wendelförmig über eine bestimmte Länge der Anschlußbohrung und ist mit zwei Pohlen zur Verbindung mit einer elektrischen Energiequelle verbunden. Durch Anschließen an die Energiequelle läßt sich der Heizdraht bis zum Schmelzpunkt des Kunststoffmaterials erhitzen, so daß das erste Rohr mit dem zweiten Rohr eineTo connect plastic pipes, they are usually welded together. EP 0 535 247 B1 shows such a welded connection between two plastic pipes. A first pipe has a connecting section with a cylindrical connecting bore, into which a connecting section of a second plastic pipe can be inserted through an opening in the bore. A resistance heating wire is embedded in the inner surface of the connecting bore. This runs in a spiral shape over a certain length of the connecting bore and is connected to two poles for connection to an electrical energy source. By connecting to the energy source, the heating wire can be heated to the melting point of the plastic material, so that the first pipe forms a

Versagt der Widerstandsheizdraht jedoch, zum Beispiel weil dieser aufgrund einer mechanischen Beschädigung des Anschlußabschnitts unterbrochen ist, kann keine Verschweißung durchgeführt werden oder es kommt zu einer nicht vollständig umlaufenden Verschweißung, die Undichtigkeiten aufweist.However, if the resistance heating wire fails, for example because it is interrupted due to mechanical damage to the connection section, welding cannot be carried out or the weld does not go all the way around and leaks occur.
Aufgabe der vorliegenden Erfindung ist es, einen Anschlußabschnitt eines Kunststoffrohres zur Verbindung mit einem weiterem Kunststoffrohr sowie eine Verbindungsanordnung, welche einen Anschlußabschnitt und einen Verbindungsabschnitt aufweist, bereitzustellen, wobei ein sichere Verbindung zwischen dem Anschlußabschnitt und dem Verbindungsabschnitt sichergestellt ist, auch wenn der Anschlußabschnitt beschädigt ist.The object of the present invention is to provide a connecting section of a plastic pipe for connection to another plastic pipe and a connection arrangement which has a connecting section and a connecting section, wherein a secure connection between the connecting section and the connecting section is ensured even if the connecting section is damaged.
Die Aufgabe wird erfindungsgemäß durch einen Anschlußabschnitt eines Kunststoffrohres, insbesondere eines aus einem Band aus einem thermoplastischen Kunststoff hergestellten Wickelrohres, zur Verbindung mit einem weiterem Kunststoffrohr aus thermoplastischem Kunststoff, umfassendThe object is achieved according to the invention by a connecting section of a plastic pipe, in particular a wound pipe made from a strip of a thermoplastic material, for connection to another plastic pipe made of thermoplastic material, comprising
- eine Längsachse,- a longitudinal axis,
- einen Basiskörper,- a base body,
- der einstückig mit dem Rohr ausgebildet ist,- which is formed in one piece with the pipe,
- der eine erste Umfangsflache aufweist, die zur thermisch-stoffschlüssigen Verbindung mit einer gegengleich ausgebildeten zweiten Umfangsflache eines Verbindungsabschnitts des weiteren Kunststoffrohres bestimmt ist,- which has a first circumferential surface which is intended for thermally bonded connection with a second circumferential surface of the same design of a connecting section of the further plastic pipe,
- mindestens zwei Widerstandsheizdrähte,- at least two resistance heating wires,
- die umlaufend in die erste Umfangsflache eingelassen sind,- which are embedded all the way around the first circumferential surface,
gelöst.solved.
Durch eine solche Ausbildung des Anschlußabschnitts ist gewährleistet, daß selbst beim Versagen eines der Widerstandsheizdrähte eine sichere Verbindung zwischen dem Anschlußabschnitt und dem Verbindungsabschnitt des weiteren Kunststoff rohres gewährleistet ist.Such a design of the connection section ensures that even if one of the resistance heating wires fails, a secure connection between the connection section and the connection section of the other plastic pipe is ensured.
Die Widerstandsheizdrähte können gemeinsame elektrische Anschlußpole aufweisen, so daß mit einem herkömmlichen Schweißgerät sämtliche Widerstandsheizdrähte betrieben werden können.The resistance heating wires can have common electrical connection poles so that all resistance heating wires can be operated with a conventional welding device.
Vorzugsweise sind die Widerstandsheizdrähte wendelförmig in die erste Umfangsflache eingelassen. Hierbei können die Widerstandsheizdrähte axial hintereinander angeordnet sein. Dadurch wird ermöglicht, daß zwischen zwei der Widerstandsheizdrähte eine umlaufende Ringnut in der ersten Umfangsflache vorgesehen werden kann. Diese Ringnut ist leitungsmäßig mit einer Bohrung zum Anschließen einer Druckluftquelle verbunden. Somit läßt sich nach Ausführen der Verschweißung die Dichtigkeit dadurch überprüfen, daß die Ringnut mit Druckluft beaufschlagt wird und überprüft wird, wie hoch der Druckabfall während einer vorgegebenen Zeitspanne ist. Somit läßt sich durch einfache Mittel die Verschweißung kontrollieren.Preferably, the resistance heating wires are embedded in the first circumferential surface in a spiral shape. The resistance heating wires can be arranged axially one behind the other. This makes it possible to provide a circumferential annular groove in the first circumferential surface between two of the resistance heating wires. This annular groove is connected in terms of pipework to a bore for connecting a compressed air source. This allows the seal to be checked after the welding has been carried out by applying compressed air to the annular groove and checking how high the pressure drop is during a predetermined period of time. This allows the welding to be checked using simple means.
Bei einem bevorzugten Ausführungsbeispiel· ist vorgesehen, daß eine Anschlußbohrung mit einer die erste Umfangsflache bildenden Innenumfangsflache versehen ist, wobei der Verbindungsabschnitt des weiteren Kunststoffrohres eine die zweite Umfangsfläche darstellende Außenumfangsflache aufweist und in die Anschiußbohrung einführbar ist.In a preferred embodiment, it is provided that a connection bore is provided with an inner circumferential surface forming the first circumferential surface, wherein the connecting section of the further plastic pipe has an outer circumferential surface representing the second circumferential surface and can be inserted into the connection bore.
Ferner wird die Aufgabe durch eine Verbindungsanordnung mitFurthermore, the task is accomplished by a connection arrangement with

einem oben beschriebenen Anschlußabschnitt und dem Verbindungsabschnitt des weiteren Kunststoffrohres gelöst, bei der die erste Umfangsfläche in Anlage zur zweiten Umfangsflache steht.a connection section described above and the connecting section of the further plastic pipe, in which the first circumferential surface is in contact with the second circumferential surface.
Zwischen zwei axial benachbarten Widerstandsheizdrähten kann eine umlaufende Ringnut in der ersten Umfangsflache oder in der zweiten Umfangsflache vorgesehen sein. Die Ringnut ist leitungsmäßig mit einer Bohrung zum Anschließen einer Druckluftquelle verbunden, so daß, wie bereits bei dem Anschlußabschnitt erläutert, eine Überprüfung der Verschweißung vorgenommen werden kann.A circumferential annular groove can be provided in the first circumferential surface or in the second circumferential surface between two axially adjacent resistance heating wires. The annular groove is connected in terms of pipework to a bore for connecting a compressed air source so that, as already explained in the connection section, the welding can be checked.
Bei einem bevorzugten Ausführungsbeispiel ist vorgesehen, daß der Anschlußabschnitt eine Anschlußbohrung mit einer die erste Umfangsflache bildenden Innenumfangsflache aufweist, und daß der Verbindungsabschnitt des weiteren Kunststoffrohres eine die zweite Umfangsflache darstellende Außenumfangsflache aufweist und in der Anschlußbohrung sitzt.In a preferred embodiment, it is provided that the connection section has a connection bore with an inner circumferential surface forming the first circumferential surface, and that the connecting section of the further plastic pipe has an outer circumferential surface forming the second circumferential surface and sits in the connection bore.
Das Kunststoffrohr kann aus Polypropylen (PP) oder aus Polyethylen (PE) hergestellt sein. Somit lassen sich entsprechende Kunststoffrohre kostengünstig herstellen. Um chemisch beständige Kunststoffrohre herzustellen, wird vorzugsweise Polyvinyllidenfluorid (PVDF) verwendet.The plastic pipe can be made of polypropylene (PP) or polyethylene (PE). This means that corresponding plastic pipes can be manufactured cost-effectively. Polyvinylidene fluoride (PVDF) is preferably used to produce chemically resistant plastic pipes.

Das weitere Kunststoffrohr 9 weist ebenfalls eine koaxial zur Längsachse 3 angeordnete Innenfläche 10 auf, welche im verbundenen Zustand der Kunststoffrohre 1, 9 bündig in die Innenfläche 4 übergeht und zum Transport von flüssigen Medien dient. Das weitere Kunststoffrohr 9 ist ebenfalls aus einem zylindrischen ersten Rohrkörper 11 und einem zweiten Rohrkörper 12 aus einem Hohlprofil 13 gefertigt.The plastic pipe 1 is connected via the connection section 2 to a connecting section 8 of a further plastic pipe 9. The further plastic pipe 9 also has an inner surface 10 arranged coaxially to the longitudinal axis 3, which, when the plastic pipes 1, 9 are connected, merges flush into the inner surface 4 and serves to transport liquid media. The further plastic pipe 9 is also made from a cylindrical first pipe body 11 and a second pipe body 12 made from a hollow profile 13.
Die Verbindung zwischen dem Anschlußabschnitt 2 und dem Verbindungsabschnitt 8 wird im folgenden, zusammen mit den Fig. 2 und 3 erläutert. Der Anschlußabschnitt 2 umfaßt einen Basiskörper 14 sowie zwei Widerstandsheizdrähte 15, 15'. In dem Basiskörper 14 ist eine Anschlußbohrung 16 eingebracht, welche eine erste Umfangsflache in Form einer konischen Innenumfangsflache 17 bildet. In die Innenumfangsflache 17 sind zwei wendeiförmige Rillen 18, 18' eingebracht. In die Rillen 18, 18' sind die Widerstandsheizdrähte 15, 15' eingelegt, so daß diese lediglich geringfügig über die Innenumfangsflache 17 hinausragen. The connection between the connection section 2 and the connection section 8 is explained below, together with Figs. 2 and 3. The connection section 2 comprises a base body 14 and two resistance heating wires 15, 15'. A connection bore 16 is made in the base body 14, which forms a first circumferential surface in the form of a conical inner circumferential surface 17. Two helical grooves 18, 18' are made in the inner circumferential surface 17. The resistance heating wires 15, 15' are placed in the grooves 18, 18', so that they only protrude slightly beyond the inner circumferential surface 17.
Die Widerstandsheizdrähte 15, 15' weisen jeweils eine Seele 19 aus einem einen elektrischen Widerstand bildenden Metalldraht auf. Die Seele 19 ist von einer Umhüllung 20 aus einem thermoplastischen Kunststoff umschlossen. Bei der Fertigung des Anschlußabschnitts 2 wird die Umhüllung 20 erhitzt und in die jeweilige Rille 18, 18' eingedrückt. Dies kann z.B. mit Heißluft geschehen, wobei die Widerstandsheizdrähte 15, 15' mit einer Rolle in die Rillen 18, 18' gedrückt werden. Somit ist sichergestellt, daß die Widerstandsheizdrähte 15, 15' fest mit dem Anschlußabschnitt 2 verbunden sind, so daß diese beim Transport oder beim Aufschieben auf den Verbindungsabschnitt 8 nicht gelöst werden können. Vorzugsweise sind die Umhüllung 20 und der Basiskörper 14 aus demselben Kunststoff gefertigt.The resistance heating wires 15, 15' each have a core 19 made of a metal wire that forms an electrical resistor. The core 19 is enclosed by a sheath 20 made of a thermoplastic material. When the connection section 2 is manufactured, the sheath 20 is heated and pressed into the respective groove 18, 18'. This can be done with hot air, for example, whereby the resistance heating wires 15, 15' are pressed into the grooves 18, 18' with a roller. This ensures that the resistance heating wires 15, 15' are firmly connected to the connection section 2 so that they cannot be loosened during transport or when pushed onto the connection section 8. The sheath 20 and the base body 14 are preferably made of the same plastic.
Die Anschlußbohrung 16 weist eine Öffnung 21 auf, durch welche der Verbindungsabschnitt 8 des weiteren Kunststoffrohres 9 in die Anschlußbohrung 16 eingeführt werden kann. Die Innenumfangsf lache 17 erweitert sich in Richtung zur Öffnung 21. Der Anschlußabschnitt 2 weist an der Öffnung 21 eine erste Stirnfläche 22 auf, welche in die Innenumfangsflache 17 übergeht. Die Innenumfangsflache 17 geht am der ersten Stirnfläche 22 beabstandeten axialen Ende der Innenumfangsflache 17 in eineThe connection bore 16 has an opening 21 through which the connecting section 8 of the further plastic pipe 9 can be introduced into the connection bore 16. The inner circumferential surface 17 widens in the direction of the opening 21. The connection section 2 has a first end face 22 at the opening 21, which merges into the inner circumferential surface 17. The inner circumferential surface 17 merges into a

erste Anlagefläche 23 über, welche um die Längsachse 3 angeordnet ist.first contact surface 23, which is arranged around the longitudinal axis 3.
Der Verbindungsabschnitt 24 des weiteren Kunststoffrohres 9 weist eine gegengleich zur Innenumfangsflache 17 ausgebildete zweite Umfangsflache in Form einer Außenumfangsflache 25 auf. An einem freien Ende des weiteren Kunststoffrohres 9 ist eine zweite Stirnfläche 27 vorgesehen, welche in die Außenumfangsflache 25 übergeht. An dem der zweiten Stirnfläche 27 entfernt angeordneten axialen Ende der Außenumfangsflache 25 geht die letztere in eine zweite Anlagefläche 26 über.The connecting section 24 of the further plastic pipe 9 has a second circumferential surface in the form of an outer circumferential surface 25, which is designed opposite to the inner circumferential surface 17. A second end face 27 is provided on a free end of the further plastic pipe 9, which merges into the outer circumferential surface 25. At the axial end of the outer circumferential surface 25 arranged remote from the second end face 27, the latter merges into a second contact surface 26.
Im eingeschobenen Zustand des Verbindungsabschnitts 8 (Fig. 3) befindet sich die Innenumfangsflache 17 in Anlage zur Außenumfangsflache 25. Ferner befinden sich die erste Stirnfläche 22 und die zweite Anlagefläche 26 sowie die erste Anlagefläche 23 und die zweite Stirnfläche 27 jeweils in Anlage. Aufgrund der Konusform der Innenumfangsflache 17 und der Außenumfangsflache 25 wird das Einführen des Verbindungsabschnitts 8 in die Anschlußbohrung 16 erleichtert. Ferner ist gewährleistet, daß zwischen der Innenumfangsflache 17 und der Außenumfangsflache 25 kein Radialspiel vorhanden ist, welches zu einem Lufteinschluß führen könnte und die Verschweißung beeinträchtigen würde. Ferner ist durch die Abstützung der ersten Stirnfläche 22 gegen die zweite Anlagefläche 26 sowie der Abstützung der ersten Anlagefläche 23 gegen die zweite Stirnfläche 27 eine Anzugsbegrenzung gewährleistet, durch die eine Überbelastung vermieden wird, bei der aufgrund der konusförmigen Innenumfangsfläche 17 und der konusförmigen Außenumfangfläche 25 hohe Radialkräfte auftreten würden, die eine zu große Verformung des Anschlußabschnitts 2 und des Verbindungsabschnitts 8 zur Folge hätten.When the connecting section 8 is pushed in (Fig. 3), the inner peripheral surface 17 is in contact with the outer peripheral surface 25. Furthermore, the first end face 22 and the second contact surface 26 as well as the first contact surface 23 and the second end face 27 are each in contact. Due to the conical shape of the inner peripheral surface 17 and the outer peripheral surface 25, the insertion of the connecting section 8 into the connection bore 16 is made easier. Furthermore, it is ensured that there is no radial play between the inner peripheral surface 17 and the outer peripheral surface 25, which could lead to air inclusion and impair the welding. Furthermore, the support of the first end face 22 against the second contact surface 26 and the support of the first contact surface 23 against the second end face 27 ensure a tightening limitation, which prevents an overload in which high radial forces would occur due to the conical inner circumferential surface 17 and the conical outer circumferential surface 25, which would result in excessive deformation of the connection section 2 and the connecting section 8.
Um im eingeschobenen Zustand des Verbindungsabschnitts 8 dasIn order to ensure that the connecting section 8 is pushed in,
Kunststoffrohr 1 und das weitere Kunststoffrohr 9 axial zu sichern, bildet der Basiskörper 14 eine vom Verbindungsabschnitt 8 abgewandte erste Stützfläche 29. Der Verbindungsabschnitt 8 weist eine entsprechende zweite Stützfläche 30 auf, welche der ersten Stützfläche 29 abgewandt ist. Somit lassen sich Spannelemente vorsehen, welche gegen die erste Stützfläche 29 und die zweite Stützfläche 30 abgestützt sind und eine Axialkraft aufbringen, so dass zwischen der Innenumfangsflache 17 und der Außenumfangsflache 25 eine Fügedruck herrscht, welcher für eine sichere Verschweißung erforderlich ist.In order to axially secure the plastic pipe 1 and the further plastic pipe 9, the base body 14 forms a first support surface 29 facing away from the connecting section 8. The connecting section 8 has a corresponding second support surface 30 which faces away from the first support surface 29. In this way, clamping elements can be provided which are supported against the first support surface 29 and the second support surface 30 and apply an axial force so that a joining pressure prevails between the inner circumferential surface 17 and the outer circumferential surface 25, which is necessary for secure welding.
Die beiden Widerstandsheizdrähte 15, 15' sind wendelförmig in zwei Rillen 18, 18' der Innenumfangsflache 17 eingelegt. Die beiden Widerstandsheizdrähte 15, 15' sind axial beabstandet hintereinander angeordnet. Zwischen den Widerstandsheizdrähten 15, 15' ist eine umlaufende Ringnut 35 in die Innenumfangsf lache 17 eingebracht. Die Ringnut 35 ist leitungsmäßig mit einer Bohrung 36 verbunden. Die Bohrung 36 ist wiederum mit einem Ventil 37 verbunden, über welches die Bohrung 36 nach außen hin abgesperrt werden kann. Über das Ventil 37 läßt sich eine Druckluftquelle anschließen, so daß die Ringnut 35 nach dem Verschweißen mit Druckluft beaufschlagt werden kann. Im Anschluß daran läßt sich die Ringnut 35 und Bohrung 36 nach außen hin absperren und nach einer vorbestimmten Zeit überprüfen, ob ein Druckabfall stattgefunden hat. Sofern der Druckabfall eine vorgegebene Grenze nicht überschreitet, ist sichergestellt, daß die Verschweißung ordnungsgemäß durchgeführt wurde.The two resistance heating wires 15, 15' are laid in a spiral shape in two grooves 18, 18' of the inner circumferential surface 17. The two resistance heating wires 15, 15' are arranged one behind the other at an axial distance. A circumferential annular groove 35 is made in the inner circumferential surface 17 between the resistance heating wires 15, 15'. The annular groove 35 is connected to a bore 36 by means of a line. The bore 36 is in turn connected to a valve 37, via which the bore 36 can be closed off to the outside. A compressed air source can be connected via the valve 37, so that the annular groove 35 can be pressurized with compressed air after welding. The annular groove 35 and bore 36 can then be closed off to the outside and checked after a predetermined time whether a drop in pressure has occurred. If the pressure drop does not exceed a specified limit, it is ensured that the welding was carried out correctly.
Nach dem Einführen des Verbindungsabschnitts 8 in die Anschlußbohrung 16 und dem axialen Verspannen des Anschlußabschnitts 2 und des Verbindungsabschnitts 8 werden die Widerstandsheizdrähte 15, 15' an eine elektrische Stromquelle angeschlossen und aufgrund des elektrischen Widerstands der See-After inserting the connecting section 8 into the connection bore 16 and axially clamping the connection section 2 and the connecting section 8, the resistance heating wires 15, 15' are connected to an electrical power source and, due to the electrical resistance of the seawater,

The melting temperature of the plastic is reached so that melting areas 28 are formed in which the material of the connection section 2 and the material of the connecting section 8 are thermally bonded to one another.
