KAISERLICHESIMPERIAL
Um während des Betriebes der Dampfkessel einzelne Röhren derselben auswechseln zu können, sind die Einrichtungen getroffen, welche auf beiliegender Zeichnung an einem in Fig. 1 in der Vorderansicht und in Fig. 2 im Längsschnitt nach A-B, Fig. 1, dargestellten Kessel veranschaulicht sind.In order to be able to replace individual tubes of the same during operation of the steam boiler, the devices are made which are illustrated in the accompanying drawing of a boiler shown in Fig. 1 in the front view and in Fig. 2 in longitudinal section according to AB, Fig. 1.
Die Röhren liegen ohne besondere Abdichtung in der hinteren Kesselwand e, wobei ihre Enden durch die Deckel c geschlossen werden.The tubes lie in the rear boiler wall e without any special sealing, their ends being closed by the cover c.
An der Vorderwand des Kessels befindet sich ein Gufsgehäuse i, welches durch die eingesetzten Ventilsitze d mit jeder einzelnen Röhre in Communication steht. Die Vorderenden der Röhren sind über die konischen Enden der Ventilsitze d gezogen, in deren Steg der Kopf einer sich durch das ganze Rohr erstreckenden gewellten Ankerschraube b befestigt ist. Letztere durchdringt mit ihrem Gewinde den Deckel c, so dafs derselbe durch eine Mutter b1 in das Rohrende fest eingedrückt werden kann.On the front wall of the boiler there is a cast housing i, which is in communication with each individual tube through the valve seats d used. The front ends of the tubes are drawn over the conical ends of the valve seats d , in the web of which the head of a corrugated anchor screw b extending through the entire tube is fastened. The thread of the latter penetrates the cover c so that it can be pressed firmly into the end of the pipe by a nut b 1.
Um nun eine Röhre auszuwechseln, senkt man das zugehörige Niederschraubventil a, dessen Muttergewinde sich in dem Verschlufsdeckel k des Gufsgehäuses i befindet, auf den Sitz d und sperrt hierdurch die Communication zwischen i und der betreffenden Röhre ab. Hierauf löst man die Mutter bl, so dafs man den Deckel c abnehmen kann, und zieht nun das beschädigte Rohr durch die Wand e heraus. Das neue Rohr wird alsdann über das Ende von d gedrückt, der Deckel c aufgesetzt und die Mutter b1 angezogen, worauf das Ventil α wieder gehoben und Wasser in das eingesetzte Rohr eingelassen werden kann.In order to replace a tube, the associated screw-down valve a, the nut thread of which is located in the closure cover k of the cast housing i, is lowered onto the seat d, thereby blocking communication between i and the relevant tube. The nut b l is then loosened so that the cover c can be removed, and the damaged tube is now pulled out through the wall e . The new pipe is then pressed over the end of d , the cover c is put on and the nut b 1 is tightened, whereupon the valve α can be raised again and water can be let into the inserted pipe.
Die Ankerschrauben b sind gewellt oder gebogen, damit sie beim Anheizen eines kalten Kessels der Ausdehnung der Röhren und anderen Theile folgen können und keine Undichtheiten entstehen.The anchor bolts b are corrugated or bent so that when a cold kettle is heated they can follow the expansion of the tubes and other parts and that no leaks occur.
