KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gemäß der Erfindung werden zum Verschließen runder Öffnungen, durch welche Rohrerweiterungs - oder andere Werkzeuge eingeführt werden, zwecks Befestigung von Metallröhrenenden in den Wänden solcher metallenen Kammern, die als Bestandteile von Dampfüberhitzern, verschiedenen Flüssigkeitsvorwärmern, Economisern, Dampfkesseln und ähnlichen Apparaten dienen, metallene Hütchen angewandt, die ebenfalls mittels eines Rohrerweiterungs- oder eines ähnlichen Werkzeugs befestigt werden.According to the invention are for closing round openings through which Pipe expansion or other tools are inserted for the purpose of fastening Metal tube ends in the walls of such metal chambers, which are part of Steam superheaters, various liquid preheaters, economizers, steam boilers and Similar devices are used, metal hats are used, which are also used by means of a Pipe expansion or similar tool.
Auf der Zeichnung ist beispielsweise ein Teil einer Sammelkammer eines gewöhnlichen Röhrendampfüberhitzers dargestellt, und zwar zeigt Fig. ι die Kammer im Durchschnitt, wobei die Schnittfläche durch die Achse einer der Röhren geführt ist. Fig. 2 ist eine Seitenansicht, und zwar derjenigen Seite, in welcher die Hütchen eingesetzt sind. Die Röhren A, A werden, wie üblich, mittels eines Rohrerweiterungswerkzeugs befestigt; die Öffnungen, durch welche dieses zwecks Aufwalzens (Umbördeln) der Röhrenenden eingeführt war, werden gemäß vorliegender Erfindung mit metallenen Hütchen B, B zugestopft. Bis jetzt wurden gewöhnlich zum Zustopfen dieser Öffnungen metallene Pfropfen mit Schraubengewinde oder mittels Bolzen zu befestigende Deckel verschiedener Bauart angewandt. Das Verschließen der Öffnungen mittels der metallenen Hütchen, die mittels eines Rohrerweiterungswerkzeugs befestigt werden, hat gegenüber anderen bis jetzt bekannten Vorrichtungen den Vorteil größerer Dichtheit der Verbindung und bietet die Möglichkeit, die Röhren beliebig aneinander anzuordnen.In the drawing, for example, a part of a collecting chamber of a conventional tubular steam superheater is shown, specifically FIG. Fig. 2 is a side view of the side in which the cones are inserted. The tubes A, A are fastened, as usual, by means of a tube expansion tool; the openings through which this was inserted for the purpose of rolling on (flanging) the tube ends are plugged with metal caps B, B according to the present invention. Up to now, metal plugs with screw threads or bolt-fastened lids of various types have been used to plug these openings. The closing of the openings by means of the metal caps, which are fastened by means of a pipe expansion tool, has the advantage over other devices known up to now that the connection is more tight and offers the possibility of arranging the pipes together as desired.
