Description

Die Erfindung betrifft eine Abdichtung mit Dichtungshälften aus Sondermetall.The invention relates to a seal with sealing halves made of special metal.

Es ist bekannt, Dichtungsringe im Körper des Sitzes und Kegels von Ventilen dadurch zu befestigen, daß zwischen Vorsprünge der Dichtungsringe und unterschnittene Flächen in Sitz und Körper Metallringe eingetrieben werden.It is known to use sealing rings in the body of the seat and cone of valves thereby to attach that between protrusions of the sealing rings and undercut surfaces Metal rings are driven into the seat and body.

Nach der Erfindung wird nur eine der Dichtungshälften in dieser Weise befestigt, die andere dagegen aufgeschrumpft. Man erhält dadurch eine wesentlich einfachere Abdichtung, die aber ebenso wirksam ist wie die Abdichtung, deren beide Hälften durch eingetriebene Ringe befestigt sind. Außerdem hat das Aufschrumpfen den Vorteil, daß die Dichtungshälfte zum Auswechseln leichter abnehmbar ist, während das Entfernen des eingetriebenen Ringes große Mühe, Kosten und Zeitverlust macht.According to the invention, only one of the sealing halves is attached in this way, the other, however, shrunk. This results in a much simpler seal, but it is just as effective as the seal, the two halves of which are attached by driven rings. aside from that shrinking on has the advantage that the sealing half is easier to replace is removable, while removing the driven ring is a great effort and expense and wasted time.

Auf der Zeichnung ist als Ausführungsbeispiel eine Dichtung für ein Lokomotivreglerventil dargestellt.In the drawing, as an exemplary embodiment, a seal for a locomotive control valve is shown shown.

Das Reglerventil α hat seinen Sitz im Reglerkopf b. Der Sitz hat einen Einsatz c aus Sondermetall, etwa Vanadiumstahl; das Ventil trägt eine auf den Einsatz c passende Buchse d aus gleichem Metall. Die Buchse d ist auf das Ventil α geschrumpft und kann, wenn nötig, noch durch mindestens eine Schraube / gehalten werden, während der Einsatz c durch einen schwalbenschwanzförmigen Kupferring e befestigt ist. Ein Lockern durch Temperatureinwirkung kann nicht vorkommen, ebensowenig wird das Sondermetall durch Erosion angegriffen; die ungünstige Wirkung des Heißdampfes ist also in beiden· Hinsichten beseitigt.The regulator valve α is located in the regulator head b. The seat has an insert c made of special metal, such as vanadium steel; the valve carries a bushing d made of the same metal that fits on the insert c. The socket d is shrunk onto the valve α and can, if necessary, still be held by at least one screw /, while the insert c is fastened by a dovetail-shaped copper ring e. Loosening due to the effect of temperature cannot occur, just as little is the special metal attacked by erosion; the unfavorable effect of the superheated steam is thus eliminated in both respects.
