Description

Gegenstand der Erfindung sind Dichtungsringe in 1.aliyrinthform,' d.-h. graphithaltige MetallkÖrper, die durch Pressen von Metallpulvern unter Anwendung von Hitze hergestellt werden und die vorzugsweise für Ventile bei hohen Drücken und hohen Temperaturen angewendet werden können.The subject of the invention are sealing rings in 1.aliyrinthform, ' i.e. graphite-containing metal bodies produced by pressing metal powders using produced by heat and which are preferable for valves at high pressures and high temperatures can be applied.

Graphithaltige Metallkörper, die besonders günstige Lauf- und Dichteigenschaften zeigen, können nach einem bewährten Verfahren durch gleichzeitiges Pressen und Erhitzen eines Pulvergemisches aus Graphit. und Metall oder Metallegierungen hergestellt werden. Das Verfahren läuft zweckmäßig so ab, daß das Pulvergemisch in ein tind derselben Form zu (lein gewünschten Teil geformt, erhitzt, gepreßt und unter Druck bis auf haulntemperatur abgekühlt wird.Metal bodies containing graphite, which have particularly favorable running and sealing properties can show according to a proven process by pressing and heating at the same time a powder mixture of graphite. and metal or metal alloys will. The process expediently proceeds in such a way that the powder mixture is in one the same shape (formed into a desired part, heated, pressed and under pressure until it is cooled down to main temperature.

Nach der Erfindung werden für den besonderen Aliwendungszweck bei Ventilen für hohe Temperaturen und hohe Drücke eine Mehrzahl von neuartig geformten Metalldichtringen nach dem bekannten Verfahren in ebenfalls neuartiger Zusamtnensetzung angewendet.According to the invention are for the special Aliwendungspunkt with Valves for high temperature and high pressure have a variety of novel shaped Metal sealing rings according to the known method in a likewise novel composition applied.

1n der Zeichnung ist eine bevorzugte Ausfülirungsforni von Dichtringen in Läbyrinthform dargestellt.1n the drawing is a preferred Ausfülirungsforni of sealing rings shown in labyrinth form.

Man erkennt in einer Langstopfbuchse, die zur Führung und Dichtung einer Welle dient, eine Mehrzahl von iln Querschnitt ballig ausgebildeten Dichtringen 2, die an dem einen Ende gegen einen Dichtring 3 von quadratischem Querschnitt liegen. An der entgegengesetzten Seite ist eine Ringscheibe i aus Metall eingebracht, die eine einwandfreie Übertragung des Anziehdruckes der Stopfbuchse auf die Dichtringe nach der Erfindung gewährleistet.You can see in a long stuffing box, which is used for guidance and sealing a shaft is used, a plurality of sealing rings with a convex cross-section 2, which are at one end against a sealing ring 3 of square cross-section. On the opposite side, an annular disk i made of metal is introduced, which A perfect transmission of the tightening pressure of the stuffing box to the sealing rings guaranteed according to the invention.

Der Vorteil dieser Labyrinthform für Dichtungsringe liegt darin, daß durch ganz leichtes Anziehen sich dieser Labyrinthdichtungsring an Stange oder Welle und Stopfbuchsenwand gut anpreßt und bei hohen Temperaturen und darüber hinaus der Ausdehnungskoeffizient in Verbindung mit der neuartigen Querschnittsform die dichtende Wirkung unterstützt. Außerdem wirken sich die verbleibenden ringförmigen Kanäle äußerst günstig aus.The advantage of this labyrinth shape for sealing rings is that by gently tightening this labyrinth sealing ring on the rod or shaft and gland wall presses well and at high temperatures and beyond the Expansion coefficient in connection with the new cross-sectional shape the sealing Effect supported. It also affects the remaining annular channels extremely cheap.

Für Dichtungsringe in Labyrinthform hat sich das folgende Mischungsverhältnis von Nichteisenmetallen als besonders günstig und geeignet erwiesen: iooo Teile Kupfer, 6o Teile Blei, 2o Teile Zink, Zoo Teile Kolloidalgraphit.The following mixing ratio is used for sealing rings in labyrinth form of non-ferrous metals proven to be particularly favorable and suitable: 10000 parts of copper, 6o parts lead, 2o parts zinc, zoo parts colloidal graphite.
