Abstract

A pipe coupling uses two outer sleeves to compress 'O' rings to provide a tight seal. A flanged sleeve (8, 9) is located on each of the pipe sections (1, 2) that are butted together (3). A central sleeve (13) is located between the flanged sleeves and two 'O' rings (15, 16) are positioned on either side of the join. Compression is applied to the 'O' rings by tightening a number of the bolts (12) located around the periphery of the flanged sleeves. As the 'O' rings are compressed a secure gripping action is applied to hold the pipes. Tapered sections on the sleeves provide accurate location and prevent over compression.

Description

"Kupplung für insbesondere Rohre" Vorliegende erfindung betrifft einc insbesondere für Rohre vorgesehene Kupplung der in der Einleitn von Anspruch 1 näher bezeichneten Art."Coupling for pipes in particular" The present invention relates to a In particular, the coupling provided for pipes in the introductory part of claim 1 in more detail designated Art.

Auf diesem Gebiet sind bereits viele Produkte bekannt geworden ud viele Verbesserungsvorschläge gemacht worden. Trotzdem ist bisher keine derartige Kupplung entstanden, die allen Anforderungen gerecht wird. Many products have already become known in this field many suggestions for improvement have been made. Nevertheless, there is none of this so far Coupling was created that meets all requirements.

Iabesondere eine gleichmässige Verteilung der arretierenden Friktionskräfte unter gleichzeitiger zufriedenstellender Abdichtung der Stossfuge gelang bei den bisher bekannten Kupplungen nicht.In particular, an even distribution of the arresting frictional forces while at the same time the butt joint was sealed satisfactorily, the hitherto known couplings are not.

Aufgabe vorliegender Erfindung ist die Schaffung einer Kupplung, die grössten Anforderungen gerecht wird und vornehmlich die oben näher genannten Mängel vermeidet. The object of the present invention is to create a clutch, meets the greatest requirements and especially those mentioned in more detail above Avoids defects.

Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass eine Kupplung der eingangs bezeichneten Art im wesentlichen wie im kennzeichnenden Teil von Anspruch 1 angegeben beschaffen ist. This object is achieved according to the invention in that a Coupling of the type described above essentially as in the characterizing part of claim 1 is specified.

Weitere Merkmale und Vorteile derErfining gehen aus folgender Beschreibung unter Hinweis auf die Zeichnung hervor. Further features and advantages of the refining emerge from the following description referring to the drawing.

Diese zeigt teilweise geschnitten eine beispielehafte Ausfühnrngsform einer erfindungsgemässen Kupplung in einer Seitenansicht. This shows an exemplary embodiment, partially in section a coupling according to the invention in a side view.

Auf der Zeichnung sind mit 1 und 2 Rohre bezeichnet, die unter Bildung einer Stossfuge 3 aneinanderstossen. Jedes der beiden Rohrenden ist von einem Kupplungsteil 4 bzw. 5 umgeben, welcher die Form einer Ringscheibe Ç bzw. 7 hat und in Richtung der Stossfuge mit einem muffenartigen Fortsatz 8 bzw 9 versehen ist, der aussenseitig stumpfkegelförmig in Richtung der Stossfuge verjüngt ist und mit Abstand von dieser endet. Nahe ihrer Peripherie ist jede Ringscheibe mit wenigstens zwei gleichmässig in Umfangsrichtung verteilten Bohrungen 10 bzw. 11 versehen, durch welche jeweils paarweise eine Schrauben-Mutter-Verbindung 12 geführt ist, welche die beiden Kupplungsteile zusammenpresst. In the drawing are designated with 1 and 2 tubes, which under formation a butt joint 3 butt against each other. Each of the two pipe ends is from a coupling part 4 and 5 surround, which has the shape of an annular disk Ç or 7 and in the direction the butt joint is provided with a sleeve-like extension 8 or 9, which is on the outside is tapered frustoconically in the direction of the butt joint and at a distance from this ends. Each ring disc is close to its periphery at least two evenly distributed in the circumferential direction bores 10 and 11 provided through which a screw-nut connection 12 is guided in pairs, which presses the two coupling parts together.

In den Raum zwischen den beiden Portsatdstirnseiten greift ein Klemmring 13 mit einer inneren, zylinderringförmigen Erhebung 14 ein, die mittig über der Stossfuge angeordnet ist und zwischen sich und den Fortsatzstirnseiten Platz für jeweils eine Ringdichtung 15 bzw. 16 last. Der Klemmring liegt mit entsprechen#geneigten Innenflächen an den Neigungsfiächen der Fortsätze 8 und 9 an. A clamping ring engages in the space between the two portsatdstirnseiten 13 with an inner, cylindrical ring-shaped elevation 14, which is centered over the Butt joint is arranged and between itself and the extension front sides space for each a ring seal 15 or 16 last. The clamping ring lies with the corresponding # inclined Inner surfaces on the inclination surfaces of the extensions 8 and 9.

Eine solche Kupplung ist einfach in der Herstellung und Anbringung. Wird die Schrauben-Mutter-Verbindung 12 angezogen, so streben die beiden Fortsätze zueinander hin, wobei sie vom Klemmring immer fester an das jeweilige Rohrende allseitig in Umfangsrichtung angepresst werden. Gleichzeitig werden die beiden Ringdichtungen komprimiert und dichten die Stossfuge beidseitig ab. Such a coupling is easy to manufacture and install. If the screw-nut connection 12 is tightened, the two extensions strive towards each other, with the clamping ring becoming more and more firmly attached to the respective pipe end on all sides be pressed in the circumferential direction. At the same time the two ring seals compresses and seals the butt joint on both sides.

Oben beschriebene und auf der Zeichnung gezeigte Sinzelheiten sind nur als nicht begrenzende Beispiele aufzufassen, die sich im Rahmen des Erfindungsgedankens beliebig abändern lassen. The details described above and shown on the drawing are to be understood only as non-limiting examples within the scope of the concept of the invention can be changed at will.
