Description

Ventilkammerverschluß für Hochdruckkompressoren Zum Verschluß von Räumen hoher Drücke werden vielfach Verschraubungen angewendet, welche aus einfachen Schraubenspindeln bestehen. Die Abdichtung wird dabei meist durch eine kreisringförmige Dichtung erzielt, welche der Verschraubung vorgelagert ist und naturgemäß einen kleineren äußeren Durchmesser hat als das Gewinde. Bei sehr hohen Drücken, wo man ohnehin höhere Beanspruchungen zulassen muß als sie sonst im Maschinenbau gebräuchlich sind, kann nun die zulässige Grenze leicht überschritten werden, wenn bei Schadhaftwerden der Dichtung der Gasdruck auf die größere Querschnittsfläche des Gewindeteils der Verschraubung wirkt.Valve chamber lock for high pressure compressors To lock Areas of high pressures are often used screw connections, which from simple Screw spindles exist. The seal is usually made by a circular ring Achieved seal, which is upstream of the screw connection and naturally a has a smaller outer diameter than the thread. At very high pressures where you can must in any case allow higher loads than is otherwise common in mechanical engineering are, the permissible limit can now easily be exceeded if damaged the seal of the gas pressure on the larger cross-sectional area of the threaded part of the Screw connection works.

Gemäß der Neuerung soll dieser Nachteil dadurch vermieden werden, daß der Raum zwischen Dichtung und Gewindeteil durch einen Abströmkanal mit dem Freien verbunden wird. Dadurch wird eine Erhöhung der Beanspruchung der Gewindegänge mit Sicherheit vermieden, und gleichzeitig bietet der Kanal die Möglichkeit, ein Undichtwerden der Dichtung durch das auftretende Geräusch austretenden Druckgases sofort wahrzunehmen.According to the innovation, this disadvantage is to be avoided by that the space between the seal and the threaded part through an outflow channel with the Outdoors is connected. This increases the stress on the threads certainly avoided, and at the same time the channel offers the possibility of a The seal becomes leaky due to the sound of compressed gas escaping perceive immediately.

In der Abbildung ist ein Ausführungsbeispiel dargestellt. a ist ein Raum sehr hohen Druckes, welcher durch die Verschraubung b abgedichtet wird. c stellt eine durch die Verschraubung b angepreßte kreisförmige Dichtungsscheibe dar.An exemplary embodiment is shown in the figure. a is a Space of very high pressure, which is sealed by the screw connection b. c represents represents a circular sealing washer pressed on by the screw connection b.

Der Raum d zwischen dieser Dichtung c und dem Gewindeteil E der Verschraubung steht durch den Kanal f mit dem Freien in Verbindung. Etwa die Dichtung durchdringendes Gas wird durch den Kanal unmittelbar ins Freie geleitet, ohne daß eine Mehrbelastung der Verschraubung bzw. des Gewindeteils eintritt.The space d between this seal c and the threaded part E of the screw connection communicates with the outdoors through channel f. Something that pervades the seal Gas is passed directly into the open through the channel without any additional load the screw connection or the threaded part occurs.
