Description
Kompensator fUr Druckmittelleitungen, insbesondere Luft- und Gasleitungen großen Durchmessern. Um den Ausgleich von Wärmedehnungen in Druckmittelleitungen zu ermöglichen, werden sog. Kugelgelenkkompensatoren angewendet, die eine Parallelverschiebung der Rohrenden möglich machen. In bekannter Weise werden die Kompensatoren durch zwischen Rohrabschnitten eingeschaltete, nachgiebige Wellrohrteile gebildet und die Innendruckkräfte durch gelenkig angeordnete Zugglieder'Übertragen. Diese Zugglieder greifen unter Einschaltung von Kugelgelenken an Flanschen der Rohrabschnitte an, die in radialer Richtung über den Außendurchmesser der Wellrohrteile hinausragen. 'Eine derartige Anordnung bedingt wegen des erforderlichen großen Durchmessers der Flansche eine schwere Ausführung derselben mit Rücksicht auf die beträchtlichen, im Sinne einer Umstülpung der Flansche wirkenden Kräfte der Zugglieder. Wegen der Herstellung einer Anzahl von Kugelgelenken ergibt sich ferner ein beträchtlicher Fertigungsaufwand. Außerdem können bei einer derartigen Anordnung infolge der Unterschiedlichen Wärmedehnungen der Rohrkörper und der Zugglieder unter Umständen beträchtliche Zusatzepannungen in den Rohrwellen verursacht werden.Compensator for pressure medium lines, especially air and gas lines large diameters. To compensate for thermal expansions in pressure medium lines To enable so-called. Ball joint compensators are used, which allow a parallel shift make the pipe ends possible. In a known way, the expansion joints are through Formed flexible corrugated pipe parts connected between pipe sections and the internal pressure forces are transmitted through articulated tension members. These tension members attack with the involvement of ball joints on the flanges of the pipe sections, which protrude in the radial direction beyond the outer diameter of the corrugated pipe parts. 'One Such an arrangement is necessary because of the large diameter of the flanges required a heavy execution of the same with regard to the considerable, in the sense an eversion of the flanges acting forces of the tension members. Because of the manufacturing a number of ball joints also results in a considerable manufacturing effort. In addition, with such an arrangement, due to the different thermal expansions the tubular body and the tension members under certain circumstances considerable additional stresses caused in the tube waves.
Gemäß der Erfindung wird eine Vermeidung der vorerwähnten Nachteile der bekannten Gelenkkompensatoren dadurch erzielt, daß anstelle weniger Gelenke aufweisender Zugglieder eine Vielzahl von elastisch verformbaren Zuggliedern ohne Gelenke zur Verbindung der gegeneinander beweglichen Rohrteile vorhanden ist. Vorzugsweise wird hierbei die Anordnung derart getroffen, daß die zur Aufnahme der Zugkräfte dienenden- elastidch verformbaren Zugglieder innerhalb der zu verbindenden Rohrteile angeordnet sind.According to the invention, the aforementioned disadvantages are avoided the known joint compensators achieved that instead of fewer joints having tension members a plurality of elastically deformable tension members without Joints to connect the mutually movable pipe parts is available. Preferably the arrangement is made such that the to absorb the tensile forces serving- elastidch deformable tension members within the pipe parts to be connected are arranged.
Im folgenden soll die Erfindung näher anhand der Zeichnung erläutert werden.In the following, the invention will be explained in more detail with reference to the drawing will.
Figuren 1 und 2 der Zeichnung geben in Länge- und Querschnitt die eine Hälfte eines erfindungsgemäß ausgebildeten Gelenkkompensators wider. Figur 3 der Zeichnung zeigt den Einbau eines erfindungegemäß ausgebildeten Gelenkkompensators in einem Leitungestrang.Figures 1 and 2 of the drawing show in length and cross section one half of a joint compensator designed according to the invention. FIG. 3 of the drawing shows the installation of a joint compensator designed according to the invention in a line section.
In Figur 1 der Zeichnung bedeutet 1 das rohrförmige Anschlußstück eines Kompensators, 2 einen Wellrohrteil, 3 einen weiteren zylin. drischen Rohrteil, der auch in seinem unteren nicht dargestellten Teil in der in Figur 1 veranschulichten Weise durch den Wellrohrkörper mit einem Anochlußrohrteil 1 verbunden ist. An der Innenseite des erweiteten Endes des Rohrkörpers 1 sind mittels eines angeschweißten zusammenhängenden Ringkörpers 4 federnde Zugglieder 5 befestigt, welche zur Übertragung der auftretenden Zugkräfte zwischen dem oberen und unteren Rohrabschnitt 1 des Kompensatorgliedes dienen. Zweckmäßigerweise können die elastischen Zugglieder 5, welche über den ganzen Umfang der RohrkÜrper 1 verteilt angeordnet sind, durch Verschraubung mit den Befeatigungsringen 4 verbunden sein. Die elastischen Zugglieder sind so angeordnet, daß sie bei Parallelverlagerungen der Rohrabschnitte 1 elastisch verformt werden. Hierbei ermöglichen die elastischen Zugglieder die Aufnahme der auftretenden Kräfte.In Figure 1 of the drawing, 1 denotes the tubular connecting piece of a compensator, 2 a corrugated pipe part, 3 a further cylinder. Drischen pipe part, which is also connected in its lower part, not shown, in the manner illustrated in Figure 1 by the corrugated pipe body with an Anochlußrohrteil 1 . On the inside of the widened end of the tubular body 1 resilient tension members 5 are fastened by means of a welded-on coherent ring body 4, which are used to transmit the tensile forces occurring between the upper and lower pipe section 1 of the compensator member. The elastic tension members 5, which are arranged distributed over the entire circumference of the tubular body 1 , can expediently be connected to the fastening rings 4 by screwing. The elastic tension members are arranged so that they are elastically deformed when the pipe sections 1 are displaced in parallel. The elastic tension members enable the forces to be absorbed.
Figur 3 der Zeichnung läßt noch genauer die Verformung eines erfindungegemäß ausgebildeten Kompensatorgliedes erkennen, wobei zur Vereinfachung in dieser Figur nur die den Schnittflächen der Rohrkörper benachbarten Federglieder angedeutet sind. In Einzelheiten kann selbstverständlich die beschriebene Anordnung abgeändert werden.FIG. 3 of the drawing shows the deformation of a compensator element designed according to the invention in more detail, with only the spring elements adjacent to the cut surfaces of the tubular bodies being indicated in this figure for the sake of simplicity. The arrangement described can of course be modified in detail.
Selbstverständlich ist die Erfindung auch bei Dampfleitungen anwendbar.The invention can of course also be applied to steam lines.
