Description
Die Erfindung bezieht sich auf einen feuchtigkeitsdichten Abschluß für Mantelrohrheizkörper mit auf eine keramische Büchse aufgeschrumpftem Mantelrohrende nach Patent 9o2 8g2 und' bezweckt eine weitere Vervollkommnung des Abschlusses dieser Art. Die Erfindung besteht darin, daß auf der keramischen Buchse ein Metallrohrstummel aufgeschrumpft ist, der mit dem Mantelrohrende durch Löten, Schweißen od. dgl. verbunden ist. Weitere vorteilhafte Einzelheiten der Erfindung sind im nachfolgenden beschrieben. Die Erfindung hat den Vorteil, daß die keramische Buchse mit dem aufgeschrumpften Metallrohrstummel als Massenteil zunächst unabhängig von der Rohrheizkörperherstellung hergestellt werden kann, wodurch eine wesentliche Vereinfachung und Verbilligung erzielt wird.The invention relates to a moisture-proof seal For tubular heating elements with the tubular end shrunk onto a ceramic sleeve according to patent 9o2 8g2 and 'aims to further perfect the completion of this Art. The invention consists in that a metal tube stub on the ceramic socket is shrunk, which od with the casing pipe end by soldering, welding. The like. Connected is. Further advantageous details of the invention are described below. The invention has the advantage that the ceramic bushing with the shrunk Metal pipe stubs as a mass part initially independent of the tubular heating element production can be produced, thereby a substantial simplification and cheaper is achieved.
Die Zeichnung veranschaulicht an einem Längsschnitt durch das Ende eines Mantelrohrheizkörpefs ein Ausführungsbeispiel der Erfindung.The drawing illustrates a longitudinal section through the end a tubular heating body an embodiment of the invention.
Auf .der keramischen Buchse i ist ein Metallrohrstummel2 aufgeschrumpft, gegebenenfalls unter Verwendung einer Dichtungsschicht 3, beispielsweise einer Glas- oder Glasurschiaht oder einer Schicht aus einem anderen beim Erhitzen weich werdenden Stoff. In der keramischen Buchse sitzt ein Metallrohr 4, das mit der keramischen Buchse auch unter Verwendung einer Dichtungsschicht 5 verbunden ist. Das Rohr 4 hat einen etwas größeren Innendurchmesser als der Durchmesser des Anschlußbolzens io, der mit der Heizwendel i i verbunden ist. Der Rohrstummel 2 ragt über die keramische Buchse hinaus und. ist mit diesem Ende durch eine Löt- oder Schweißnaht 7 mit demMantelrohr 6 verbunden, in welchem ,die Heizwendel i i in einem Isolierstoff 8 eingebettet ist. Das hat den Vorteil, daß beim Verbinden des Rohrstummels mit dem Rohr 6 durch Löten, Schweißen od. dgl. ein Wiederweichwerden der Gfasurschicht 3 verhindert wird. Der Hohlraum zwischen der keramischen Buchse i und dem Isolierstoff 8 ist durch ein isolierendes Füllstück 9 ausgefüllt.A metal tube stub 2 is shrunk onto the ceramic socket i, optionally using a sealing layer 3, for example a glass or glaze slip or a layer of another which softens on heating Material. In the ceramic socket sits a metal tube 4, which is connected to the ceramic Bushing is also connected using a sealing layer 5. The pipe 4 has a slightly larger inside diameter than the diameter of the connecting bolt io, which is connected to the heating coil i i. The stub tube 2 protrudes over the ceramic Jack out and. is connected to this end by a soldered or welded seam 7 with the jacket pipe 6 connected, in which the heating coil i i embedded in an insulating material 8 is. This has the advantage that when connecting the pipe stub to the pipe 6 through Soldering, welding or the like. Resolving of the fiberglass layer 3 is prevented. The cavity between the ceramic socket i and the insulating material 8 is through an insulating filler piece 9 is filled.
