Abstract
Description
Die Erfindung betrifft eine zugfeste Rohrverbindung zwischen einer Muffe und einem rohrförmigen Anschlussstück mittels einer bajonettartigen Verriegelung, wobei die Bajonettmatrize der Muffe und die Bajonettpatrize dem Anschlussstück zugeordnet ist, wobei die Bajonettpatrize an einem auf dem Mantel des Anschlussstücks drehbar gelagerten Kupplungsring ausgebildet ist und wobei der Kupplungsring eine Umfangsnut zur Aufnahme der Klauen der Bajonettmatrize aufweist, entsprechend dem Oberbegriff des Anspruchs 1.The The invention relates to a tensile pipe connection between a sleeve and a tubular one connector by means of a bayonet-like locking, the bayonet matrix the socket and the bayonet patrix are assigned to the connector, the bayonet male being rotatable on a on the jacket of the connector mounted coupling ring is formed and wherein the coupling ring has a circumferential groove for receiving the claws of the bayonet die, according to the preamble of claim 1.
Zugfeste Rohrverbindungen sind in zahlreichen Ausführungen z. B. im Wasser- und Gasrohrleitungsbau bekannt. Hier stellt sich häufig die Aufgabe, Anschlussformstücke oder Rohrspitzenden mit der Muffe einer Armatur, z.B. eines Schiebers, zu verbinden. Dabei weist das anschlussstückseitige Ende der Armatur eine Muffe auf mit einer Bajonettmatrize, in die die Bajonettpatrize des Anschlussstücks axial eingesteckt und dann durch Verdrehen um die Längsachse verriegelt werden kann.tensile strength Pipe connections are available in numerous versions e.g. B. in water and Gas pipeline construction known. This is often the task of connecting fittings or Pipe tips with the socket of a fitting, e.g. a pusher, connect to. The end of the fitting on the connector side faces a sleeve with a bayonet matrix into which the bayonet matrix of the connector inserted axially and then by turning around the longitudinal axis can be locked.
Im Rahmen der vorliegenden Erfindung wird unter Bajonettmatrize der Muffe eine Bajonettkupplungsanordnung verstanden, bei der die sich über einen Teilumfang erstreckenden Bajonettnocken im wesentlichen radial nach innen weisen, wohingegen das Gegenstück, die Bajonettpatrize, am Ende des Anschlussstücks ebenfalls teilumfänglich angeordnete, jedoch im wesentlichen radial vorstehende Bajonettnocken aufweist.in the Within the scope of the present invention, the bayonet matrix is used Must understand a bayonet coupling arrangement in which the one over Partially extending bayonet cams substantially radially inside, whereas the counterpart, the bayonet patrix, on the End of the connector also partially arranged, but essentially radially projecting bayonet cams having.
Die Rohrverbindung wird also im wesentlichen dadurch hergestellt, dass man das die Bajonettpatrize ausbildende Ende des Anschlussstücks in die Bajonettmatrize der Muffe einführt und dann um einen gewissen Umfangswinkel von z.B. 45° dreht, um die Riegelposition zu erreichen. Sind an dem Anschlussformstück weitere Teile, insbesondere Abzweigungen angebracht, müssen diese den Schwenkweg mit ausführen. Je nach Länge der Anschlussstücke kann dies hinderlich sein.The Pipe connection is therefore essentially made in that the end of the connecting piece forming the bayonet matrix into the bayonet matrix the sleeve introduces and then by a certain circumferential angle of e.g. 45 ° rotates around the To reach the latch position. Are more on the connection fitting Parts, in particular branches attached, must have the swivel path To run. Depending on the length of the connectors this can be a hindrance.
Eine
Rohrverbindung, von der die Erfindung ausgeht, ist aus
Der vorliegenden Erfindung liegt nun im wesentlichen die Aufgabe zugrunde, eine Rohrverbindung der im Oberbegriff des Anspruchs 1 näher umrissenen Art so weiterzubilden, dass ein Lösen des Kupplungsrings auch unter widrigen Betriebsumständen sicher verhindert wird.The The present invention is essentially based on the object a pipe connection of the outlined in the preamble of claim 1 Kind in such a way that a release of the coupling ring also under adverse operating conditions is safely prevented.
Die Erfindung löst diese Aufgabe mit den Merkmalen des Anspruchs 1 und ist demzufolge dadurch gekennzeichnet, dass die Umfangsnut einen zusätzlichen axialen Freiraum vor der Muffe ausbildet zur Aufnahme von Klauen eines auf den Kupplungsring aufsetzbaren bajonettartigen Sicherungsrings, der mittels wenigstens eines Riegelorgans gegen Rückdrehen an der Muffe festlegbar ist.The Invention solves this task with the features of claim 1 and is therefore characterized in that the peripheral groove an additional axial free space in front of the sleeve is designed to accommodate claws a bayonet-type circlip that can be placed on the coupling ring can be fixed against turning back on the sleeve by means of at least one locking element is.
Der Kern der Erfindung besteht also im wesentlichen darin, die axiale Länge des Kupplungsrings zu vergrößern, um es dadurch als 'Aufnahmebajonett' für den Sicherungsring zu verwenden. Insoweit hat nun der Kupplungsring eine Doppelfunktion. Oder, mit anderen Worten: der Sicherungsring hält nun gemeinsam mit dem Kupplungsring die Rohrverbindung absolut zugfest zusammen.The The essence of the invention is essentially the axial Length of Clutch ring to enlarge it as a 'mounting bayonet' for the locking ring to use. In this respect, the coupling ring now has a double function. Or, in other words: the locking ring now holds together with the coupling ring the pipe connection is absolutely tensile.
Eine Ausgestaltung sieht vor, dass das Riegelorgan von einem Stift, Bolzen, einer Schraube od. dgl. gebildet ist, der/die – von außen betätigbar – den Sicherungsring durchgreift und in die Muffe eingreift. In einem besonders einfachen Fall genügt daher z.B. eine den Sicherungsring vorzugsweise axial durchgreifende Schraube, um die Rohrverbindung absolut sicher zu fixieren.A Design provides that the locking member by a pin, bolt, a screw or the like. is formed which - which can be actuated from the outside - passes through the locking ring and engages in the sleeve. In a particularly simple case, it is therefore sufficient e.g. a screw, preferably axially penetrating the locking ring, to fix the pipe connection absolutely securely.
Der Sicherungsring kann außerdem eine weitere Funktion übernehmen, indem er den Übergangsbereich zwischen der Muffe und dem Anschlussstück überdeckt und den Kupplungsring durch Abdichtung des Übergangsbereichs gegen in die Rohrverbindung eindringende Verunreinigungen ebenso schützen wie er einen Austritt von Fluid aus der Rohrleitung verhindern kann.The Circlip can also take on another function, by making the transition area covered between the sleeve and the connector and through the coupling ring Sealing the transition area against impurities entering the pipe connection as well protect how it can prevent fluid from escaping from the pipeline.
Dazu ist des weiteren vorgesehen, dass der Sicherungsring den Übergangsbereich zwischen der Muffe und dem Anschlussstück mittels Ringdichtung und/oder Ringlippe abdichtet. Konkret ist bei einem bevorzugten Ausführungsbeispiel die Anordnung so getroffen, dass der Sicherungsring eine Aufnahmenut für einen Dichtring aufweist, der sowohl am Anschlussstück als auch am Kupplungsring anliegt und der Sicherungsring an seiner zur Stirnfläche der Muffe weisenden Stirnfläche eine umlaufende Lippe als Dichtlippe aufweist.To it is further provided that the circlip the transition area between the sleeve and the connecting piece by means of a ring seal and / or Seals ring lip. Is specific in a preferred embodiment the arrangement is such that the locking ring is a receiving groove for one Has sealing ring, both on the connector and on the coupling ring rests and the locking ring on its face to the Sleeved face has a circumferential lip as a sealing lip.
Der Sicherungsring ist bevorzugt ein Spritzgießbauteil und besteht aus einem formelastischen Material wie z.B. einem Elastomer oder Polyethylen (PE).The locking ring is preferably an injection molded component and consists of a resilient material such as an elastomer or polyethylene (PE).
