Description

Bei der dehnbaren Rohrverbindung nach Patent 306227 ist das in den Zwischenraum der teleskopartig ineinandergesteckten Rohrenden eingeschaltete Metallrohr von größerem Dehnungsvermögen entweder ein glattes Rohr oder ein gewelltes, das zur Erhaltung des Wellenabstandes. in eine Asbestmasse eingebettet ist. Bei Leitungen mit hohem Druck erweist sich diese Ausführung indessen als Ersatz für die erstere als nicht genügend, da dann, sobald.die Länge des Wellrohres ein gewisses Maß überschreitet, der an der Außenseite des Wellrohres wirksame Druck das Rohr unter Zusammenpressen der Asbestfüllung gegen das Innenrohrende drückt und das Wellrohr deformiert. Um diesen Mangel zu beseitigen und die Ausführungsforrn mit Wellrohr auch für hohen Druck geeignet zu machen, wird gemäß der vorliegenden Zusatzerfindung in das Wellrohr ein Schraubenband von' gleicher Steigung wie das Wellrohr aus Bandstahl oder Bandeisen eingelegt.
. Die Zeichnung zeigt in Fig. 1 einen Längsschnitt durch die ganze Rohrverbindung, und in Fig. 2 einen Teilschnitt in größerem Maßstab.In the expandable pipe connection according to patent 306227, the metal pipe with greater expansion capacity inserted into the space between the telescopically nested pipe ends is either a smooth pipe or a corrugated one, which is used to maintain the distance between the shafts. is embedded in an asbestos mass. In the case of lines with high pressure, however, this version proves to be insufficient as a substitute for the former, since as soon as the length of the corrugated pipe exceeds a certain level, the pressure acting on the outside of the corrugated pipe, compressing the asbestos filling against the inner pipe end presses and deforms the corrugated pipe. In order to eliminate this deficiency and to make the embodiment with corrugated pipe also suitable for high pressure, according to the present additional invention, a screw band of the same pitch as the corrugated pipe made of steel strip or band iron is inserted into the corrugated pipe.
. The drawing shows in Fig. 1 a longitudinal section through the entire pipe connection, and in Fig. 2 a partial section on a larger scale.

s5 α ist das Innenrohrende, 5 das Außenrohrende, zwischen deren Flanschen g und f das Metallwellrohr d eingespannt ist, das gegen den Bund c des Innenrohres α drückt und so durch seine größere Längsdehnung die Leitungsdehnungs5 α is the inner pipe end, 5 the outer pipe end, between the flanges g and f of the corrugated metal pipe d is clamped, which presses against the collar c of the inner pipe α and so the line expansion due to its greater longitudinal expansion

30: ausgleicht. In das Wellrohr d ist ein Schraubenband e aus Band- oder Flacheisen eingelegt dessen Außenkanten in den Scheitelpunkten der Wellen des Wellrohres d liegen. Hierdurch wird einmal verhütet, daß durch den Druck zwischen dem Wellrohr d und dem Rohr b ersteres gegen das Rohr α gepreßt wird, und ferner hält auch dieses eingelegte starke Schraubenband e die Wellen des Wellrohres d in dem der Steigung entsprechenden Abstand voneinander, so daß die Asbestfüllung fortfallen kann. Der Außendruck drückt die Wellenscheitelkanten in dem kurzen Steigungsabstand gegen · das eingelegte Schraubenband e, wodurch die Wellenform und der Wellenabstand erhalten bleiben.30 : balances. In the corrugated pipe d , a screw band e made of strip or flat iron is inserted, the outer edges of which lie in the vertices of the corrugations of the corrugated pipe d. This prevents once that the pressure between the corrugated pipe d and the pipe b presses the former against the pipe α , and also this inserted strong screw tape e holds the waves of the corrugated pipe d at the distance corresponding to the pitch, so that the Asbestos filling can be omitted. The external pressure pushes the corrugation crest edges in the short pitch distance against the inserted screw band e, whereby the wave shape and the corrugation distance are maintained.

In besonderen Fällen kann auch eine Asbestfüllung neben der Schraubenbandeinlage angewendet werden.In special cases, an asbestos filling can also be used in addition to the screw tape insert will.
