Description

Einrichtung zur Verhinderung des Eintritts von Fremdkörpern in die Ventilspindellagerung bzw.-führung bei Ventilen für Dampf-oder Gasturbinen Die Neuerung betrifft eine Einrichtung zur Verhinderung des Eintritts von Fremdkörpern in die Ventilspindellagerung bzw. -führung bei Ventilen für Dampf-oder Gasturbinen.Device to prevent foreign bodies from entering the Valve spindle bearing or guide for valves for steam or gas turbines The innovation relates to a device for preventing foreign bodies from entering the Valve spindle bearing or guide for valves for steam or gas turbines.

Bekanntlich werden mit dem Dampf-oder Gasstrom Fremdkörper mitgeführt, die so klein sind, daß sie trotz vorgeschalteter Siebe in die Ventilspindellagerung bzw. -führugn eintreten und dort Ursache eines erhöhten Verschleißes dieser Teile sind. Die Neuerung will diesen Nachteil beheben.It is known that foreign bodies are carried along with the steam or gas flow, which are so small that they are in the valve spindle bearing despite the upstream sieve or guiding occur and there cause increased wear and tear on these parts are. The innovation aims to remedy this disadvantage.

Die Neuerung besteht darin, daß eine mit der Ventilspindel fest verbundenen Schutzbuchse vorgesehen ist, die sowohl in geöffnetem als auch in geschlossenem Zustand des Ventils die Spindelführung gegenüber den vom Dampf- oder Gasstrom mitgeführten Fremdkörpern abdeckt.The innovation is that one is firmly connected to the valve spindle Protective socket is provided, both in the open and in the closed State of the valve, the spindle guide compared to that carried by the steam or gas flow Foreign bodies.

Der Vorteil der Neuerung ist, daß der Verschleiß der Spindel und der Spindelführung wesentlich herabgesetzt und eine engere Passung und damit eine gleichseitig erzielte genauere Spindelführung ermöglicht wird.The advantage of the innovation is that the wear of the spindle and the Spindle guide significantly reduced and a closer fit and thus an equilateral achieved more precise spindle guidance is made possible.

In der Zeichnung ist schematisch ein Ausführungsbeispiel nach der Neuerung wiedergegeben. In den Figuren 1 und 2 ist ein Schnellschlußventil für eine Dampfturbine dargestellt. Fig. 1 zeigt das Ventil in geschlossener Stellung, während Fig. 2 das Ventil in geöffneter Stellung wiedergibt. Gemäß der Neuerung ist mit der ventilspindel 11 eine Schutzbuchse 12 fest verbunden. Die Schutzbuehse, die im wesentlichen aus einem hülsenähnlichen Körper besteht, überdeckt die Ventilspindellagerung 14.In the drawing, an embodiment is schematically shown in FIG Innovation reproduced. In Figures 1 and 2 is a quick-acting valve for a Steam turbine shown. Fig. 1 shows the valve in the closed position while Fig. 2 shows the valve in the open position. According to the innovation a protective sleeve 12 is firmly connected to the valve spindle 11. The rifle, which essentially consists of a sleeve-like body, covers the valve spindle bearing 14th

Der Stopfbuchsenhalter 13 weist ebenfalls eine hülsenartige Verlängerung 15 auf, so daß auch bei völlig geöffnetem Ventil eine Überdeckung der Ventilspindellagerung bzw. -führugn gegeben ist. Durch die Schutzbuchse 12 wird erreicht, daß die mit der Dampfströmung in Pfeilrichtung 16 mitgeführten Fremdkörper nicht mehr an die Ventilspindelführugn gelangen können. Schutzanspruch:The gland holder 13 also has a sleeve-like extension 15, so that even when the valve is fully open, the valve spindle bearing is overlapped or leadership is given. The protective sleeve 12 ensures that the with foreign bodies carried along by the steam flow in the direction of arrow 16 no longer reach the Valve spindle guides can get. Protection claim:
