Flaschendichtung für Höchstdruckrohre.Bottle seal for high pressure pipes.
Vorliegende Erfindung bezieht sich auf die Abdichtung von Rohren für Höchstdruckkessel, insbesondere auf die Flanschendichtung für die Wasser- bzw. Dampfsammler von solchen. Bei den in Frage kommenden hohen Drucken lassen sich Rohre mit angegossenen Flanschen nicht verwenden. Die Flansche müssen daher in besonderer Weise an den Rohren befestigt werden. In der Regel geschient dies durch Schraubengewinde, und zwar sogenanntes Gasgewinde, welches die Gefahr des Abrutschens der Flansche mit sich bringen kann.The present invention relates to the sealing of pipes for high pressure boilers, especially on the flange seal for the water or steam collector of such. With the high ones in question Pipes with cast flanges cannot be used for printing. The flanges must therefore be attached to the pipes in a special way. Usually splinted this by means of screw threads, specifically so-called gas threads, which reduce the risk of the flanges slipping off can bring.
Die Erfindung besteht darin, daß die aus den Flanschen hervorragenden Rohrenden einer Rohrverbindung ringsherum geschlitzt und keilartig auseinandergetrieben sind, und daß in diese keilförmige Ringnut ein entsprechender doppelkeilförmiger Ring aus Weich-The invention consists in that the pipe ends protruding from the flanges a pipe connection are slotted around and driven apart like a wedge, and that in this wedge-shaped ring groove a corresponding double-wedge-shaped ring made of soft
ao eisen, Nickel oder anderem Metall von ähnlichen Eigenschaften eingesetzt ist. Auf diese Weise wird selbst bei höchsten Drücken eine völlig dichte Flanschenverbindung für Rohre geschaffen, bei der die Gefahr des Abrutschens der Flansche vermieden ist.ao iron, nickel or other metal with similar properties is used. To this Even at the highest pressures, a completely tight flange connection for pipes is achieved created in which the risk of the flanges slipping off is avoided.
Auf der Zeichnung sind zwei Ausführungsformen der Erfindung dargestellt. Two embodiments of the invention are shown in the drawing.
Abb. ι zeigt eine Flanschenverbindung im Schnitt mit zwei verschiedenen· Dichtungen.Fig. 1 shows a flange connection in section with two different seals.
Abb. 2 und 3 zeigen den Herstellungsgang der oberen Dichtung gemäß Abb. 1.Fig. 2 and 3 show the production process of the upper seal according to Fig. 1.
Mit ι sind die Flansche bezeichnet, die mittels Gewindes mit den Enden der Rohre 2 und 3 verbunden sind, derart, daß die Enden der Rohre um einen gewissen Betrag aus den Flanschen hervorragen. Gemäß der oberen Dichtungsart wird in die Enden der Rohre 2 und 3 ein Schlitz 4 (Abb. 2) eingeschnitten, der dann auf der Drehbank oder in irgendeiner Weise auseinandergedrückt wird, derart, daß der Außenring nach außen gepreßt wird (s. Abb. 1, oben). Dadurch wird verhindert, daß die Flansche von den Rohrenden heruntergezogen werden können." Zwischen die Enden der Rohre wird ein doppelkeilförmiger Ring aus weichem Eisen, Nickel oder anderem Metall eingelegt, der stets nachgezogen werden kann und auch bei Bewegungen des Rohres dicht hält.The flanges are denoted by ι, which are threadedly connected to the ends of the tubes 2 and 3 are connected in such a way that the ends of the tubes by a certain amount from the Flanges protrude. According to the above type of seal, the ends of the tubes 2 and 3 a slot 4 (Fig. 2) is cut, which is then cut on the lathe or in any Way is pressed apart, in such a way that the outer ring is pressed outwards (see Fig. 1, above). This prevents that the flanges can be pulled down from the pipe ends. "Between the ends of the pipes there is a double wedge-shaped Inlaid ring made of soft iron, nickel or other metal, which can always be tightened and also when moving of the pipe keeps tight.
