Description

Speisewasservorwärmer aus Bußeisernen Rohren und Quersammlern. Es ist bekannt, zwischen den b ßeisernen Röhren von Rauchgaswasservorwärmern und den Quersammlern eine Nippelverbindung zu verwenden.Feed water preheaters made from iron pipes and cross-headers. It is known between the iron pipes of flue gas water preheaters and the To use a nipple connection for cross collectors.

Dieser Verbindung fehlt die Elastizität, um Stöße oder Wärmeausdehnungen in den Rohren aufzunehmen.This connection lacks the elasticity to withstand impacts or thermal expansion to be included in the pipes.

Dieser Nachteil wird durch die neue, wellrohrartige Nippelverbindung beseitigt. Die Abb. r bis 5 zeigen wellrohrartige Nippel a mit ein oder mehreren Wellen, deren Enden einesteils in den Bußeisernen Röhren, andernteils in den Quersammlern durch Verschrauben, Einwalzen o. dgl. befestigt sind. Die Elastizität dieser Verbindungstücke ist durch die Wellen außerordentlich groß, wodurch sie alle Spannungen zwischen den Röhren und Sammlern, welche durch Stöße, Wärmeausdehnungen usw. entstehen, aufnehmen. Soll aus einer Rohrgruppe ein einzelnes Rohr z. B. zwecks Reparatur herausgezogen werden, so können die um das auszuwechselnde Rohr herumliegenden Rohrstränge infolge der Elastizität der wellrohrartigen Nippel an den Auflagerstellen der Kopfenden auseinandergedrückt werden, so daß das dazwischenliegende Rohr frei liegt und ausgewechselt werden kann.This disadvantage is caused by the new, corrugated tube-like nipple connection eliminated. Figs. R to 5 show corrugated tube-like nipples a with one or more Shafts, the ends of which are partly in the penis-iron tubes, partly in the cross-headers are fastened by screwing, rolling in or the like. The elasticity of these connectors is extraordinarily large due to the waves, eliminating all tension between them the tubes and collectors, which are caused by impacts, thermal expansion, etc. If a single pipe z. B. pulled out for repair so the pipe strings lying around the pipe to be replaced can as a result the elasticity of the corrugated tube-like nipple at the support points of the head ends be pushed apart so that the intermediate tube is exposed and replaced can be.
