Die Erfindung betrifft eine Kupplung für Kunststoffrohre, deren Enden gleichartig kugelförmig ausgebildet und in einem äußeren und gleichzeitig in einem inneren Teil mit kugelförmigen Abschnitten abdichtend gelagert sind. Rohrkupplungen dieser Art zum Ausgleich von Rohrversetzungen od. dgl. sind bekannt, sie sind schnell und leicht zusammenschließbar und gewährleisten in der Praxis eine Abwinkelbarkeit bis zu 30°.The invention relates to a coupling for plastic pipes, the ends of which are similarly spherical and in an outer and at the same time in an inner part with spherical sections are stored sealingly. Pipe couplings of this type to compensate for pipe dislocations or the like. Are known, they are quick and easy to connect and ensure that they can be bent in practice up to 30 °.
Kupplungen der vorerwähnten Art können auch Anwendung finden für den Zusammenschluß von nach dem Filament-Winding-Verfahren hergestellten, glasfaserverstärkten Kunststoffrohren, die bei ausreichenden Festigkeitseigenschaften gegenüber herkömmlichen Stahl- oder Gußeisen-Rohren zahlreiche Vorteile aufweisen. Es ist allerdings in diesem Zusammenhangbekannt, daß bei solchen Rohrleitungen, stehen sie unter Druck, insbesondere innerhalb der anfänglichen 24 Stunden nach ihrer Inbetriebnahme, sehr starke Längsdehnungen auftreten, welche bei Ausbildung einer Kupplung wie vorerwähnt besonders die Übergangsstellen vom längsausgerichteten Rohr zu den kugelförmigen Enden gefährden und in diesen Bereichen ein Einreißen der Wandungen begünstigen. Couplings of the aforementioned type can also be used for the connection of glass fiber reinforced plastic pipes manufactured using the filament winding process, which, if sufficient Strength properties compared to conventional steel or cast iron pipes numerous Have advantages. However, in this context it is known that in such pipelines, are they under pressure, especially within the initial 24 hours after commissioning, very strong longitudinal expansions occur, which especially when a coupling is formed, as mentioned above endanger the transition points from the longitudinally aligned pipe to the spherical ends and in favor these areas tearing of the walls.
Der Erfindung liegt nun die Aufgabe zugrunde, eine Kupplung für nach dem Filament-Winding-Verfahren hergestellte, glasfaserverstärkte Kunststoffrohre zur Verfügung zu stellen, bei welcher ein solches Einreißen der unter Druck stehenden Rohrleitungen durch die auftretenden Längsdehnungen wirksam verhindert wird. Diese Aufgabe wird da- , durch gelöst, daß man die Rohre und ihre kugelförmigen Enden außen mit einer Lage längsorientierter und mit einer diese Lage überdeckenden Lage umfangsorientierter Rowing-Stränge umhüllt. Bei einer solchen Anordnung vermögen nun die längsorientierten Rowingstränge eine Längsdehnung bis zu 3% aufzunehmen, sie werden in ihrer Lage durch die umfangsorientierten Rowingstränge festgehalten, so daß dadurch ein Abheben im Laufe der Zeit wirksam verhindert wird.The invention is now based on the object of providing a coupling for using the filament winding method to provide manufactured, glass fiber reinforced plastic pipes, in which a such tearing of the pipelines under pressure due to the longitudinal expansions that occur is effectively prevented. This object is achieved by the fact that the tubes and their spherical Ends outside with a layer that is longitudinally oriented and with a layer that covers this layer encased circumferentially oriented rowing strands. With such an arrangement, the longitudinally oriented Rowing strands take up a longitudinal stretch of up to 3%, they will through their position the circumferentially oriented rowing strands are held, so that a lifting off over time is effective is prevented.
Die Erfindung wird nachstehend an Hand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigtThe invention is described below with reference to an embodiment shown in the drawing described in more detail. It shows

Die Enden der glasfaserverstärkten Kunststoffrohre 1 und 2, welche nach dem Filament-Winding-Verfahren hergestellt sind, sind mit zwei gleich großen Kugelschalen 3 und 4 versehen. Gegen diese RohrkupplungThe ends of the glass fiber reinforced plastic pipes 1 and 2, which are manufactured using the filament winding process, are provided with two spherical shells 3 and 4 of the same size.

Kugelschalen liegt innen ein Kupplungsglied 6 mit zentraler Bohrung 5 und außen je ein Kupplungsglied 9 bzw. 10 an, Schrauben 7 und 8 verspannen die einzelnen Kupplungsglieder gegeneinander. Zwischen innerem Kupplungsglied 6 und den Kugelschalen 3 und 4 sind Dichtungen 11 und 12 angeordnet, zusätzliche Dichtungen können je nach dem Erfordernis der Praxis noch vorgesehen sein. A coupling member 6 with a central bore 5 rests on the inside and a coupling member 9 or 10 on the outside, screws 7 and 8 brace the individual coupling members against one another. Seals 11 and 12 are arranged between the inner coupling member 6 and the ball sockets 3 and 4 ; additional seals can also be provided depending on the practical requirements.
Wie aus F i g. 2 ersichtlich, ist nun erfindungsgemäß das Rohr 1 wie auch die Kugelschale 3 außen zunächst mit einer ersten Lagea längsorientierter Rowingstränge umhüllt, und diese Rowingstränge werden von einer zweiten Lage b umfangsorientierter Rowingstränge überdeckt. Entsprechendes gilt für das Rohr 2 mit dessen Kugelschale 4. Diese Rowingstränge verhindern wirksam in einfacher Weise ein Einreißen der Rohrleitung, insbesondere in deren gefährdeten Übergangsstellen zwischen längsausgerichtetem Rohr 1, 2 und Kugelschalen 3, 4, wenn die Rohrleitungen unter Druck stehen und dabei Längsdehnungen auftreten.As shown in FIG. 2, the pipe 1 as well as the spherical shell 3 is now, according to the invention, initially enveloped on the outside with a first layer a of longitudinally oriented rowing strands, and these rowing strands are covered by a second layer b of circumferentially oriented rowing strands. The same applies to the pipe 2 with its spherical shell 4. These rowing strands effectively prevent the pipeline from tearing in a simple manner, especially in the endangered transition points between the longitudinally aligned pipe 1, 2 and spherical shells 3, 4 when the pipelines are under pressure and longitudinal expansion occurs .
