Description

Labyrinthstopfbüchse Zusatz zum Patent 482 825 Die vorliegende Erfindung bezieht sich auf die weitere Ausbildung der durch das Patent 482 825 geschützten Labyrinthstopfbüchse mit auswechselbaren Liderungsringen, zwischen denen durch Spalte verbundene Kammern vorgesehen sind, insbesondere auf die weitere Ausbildung der Ausführungsform, bei der zwischen jedem äußeren und inneren Liderungsring zwei oder mehr Spalte und zwischen diesen Spalten Zwischenkammern vorgesehen sind. Erfindungsgemäß erhalten diese Zwischenkammern-die Form von Spalten, denen man zweckmäßigerweise eine solche Richtung gibt, daß die Spaltflüssigkeit in ihnen umgelenkt wird.Labyrinth stuffing box Addendum to Patent 482 825 The present invention relates to the further development of those protected by patent 482,825 Labyrinth stuffing box with interchangeable eyelid rings, between which there is a gap connected chambers are provided, in particular on the further training of the Embodiment in which between each outer and inner eyelid ring two or more gaps and intermediate chambers are provided between these gaps. According to the invention get these intermediate chambers-the form of columns, which one expediently gives such a direction that the fission liquid is deflected in them.

Auf der Zeichnung ist ein Liderungsringpaar gemäß der Erfindung veranschaulicht. Zwischen dem äußeren Liderungsring a und dem auf der Welle h sitzenden inneren Liderungsring e sind die Spalte il und i2 vorgesehen. Die Zwischenkammer erhält die Form eines Spaltes o, dem man vorteilhafterweise eine solche Richtung gibt, daß zwecks Energieverzehrung die Spaltflüssigkeit (bei abzudichtenden Stoffen von geringem spezifischen Gewicht, wie Wasserdampf, Luft oder Gase, benutzt man einen besonderen Sperrstoff, z. B. Wasser oder Quecksilber) in ihm umgelenkt wird.In the drawing, a pair of eyelid rings according to the invention is illustrated. Between the outer ring a and the inner ring sitting on the shaft h e columns il and i2 are provided. The intermediate chamber takes the form of a Gap o, which is advantageously given such a direction that for the purpose of energy consumption the cracking liquid (in the case of materials to be sealed with a low specific weight, such as water vapor, air or gases, a special barrier material is used, e.g. B. Water or mercury) is diverted in it.

Durch die Anordnung des Spaltes o erreicht man eine Vergrößerung der Spaltlänge jedes Spaltelementes und somit eine Erhöhung der Drosselwirkung und schafft die Möglichkeit, die Zahl der Labyrinthelemente zu verringern. Hierdurch tritt eine Verkürzung der ganzen Dichtung in Richtung der Wellenachse ein, und man genügt dem Bestreben, jede Dichtung so kurz wie möglich zu machen.The arrangement of the gap o increases the Gap length of each gap element and thus an increase in the throttling effect and creates the possibility of reducing the number of labyrinth elements. This causes a Shorten the entire seal in the direction of the shaft axis, and that is enough Strive to make each seal as short as possible.
