   Die   Anlassvorrichtung besteht   aus dem Hauptabsperrventile a und aus dem Regelventile    < ?, beide   durch Druckkolben bewegt. Das Uauptabsperrventil wird im Falle des Überschreitens der zulässigen Drehzahl vom Sicherheitsregler aus oder zwecks plötzlichen Abstellens von Hand aus mittels Druckflüssigkeit geschlossen. Zum Anlassen dient das   Regelvontil.   



   Die Erfindung besteht darin, dass das   Hauptabspcrrventil   nicht geöffnet werden kann, bevor das Regelventil c geschlossen ist, zu dem Zwecke, um die Turbine vor jedem plotz-

 belastete Ventil a kann durch den Öldruck nicht geöffnet werden. Erst wenn das Regelventil geschlossen ist, wird der durch das Hilfsventil strömende Dampf im Raume d gestaut und dadurch ein Druckausgleich auf beiden Seiten des Ventih's a erzielt. Letzteres kann sich nunmehr öffnen und die Turbine kann vom Regelventile aus angelassen werden. 



   Statt des Ventiles a kann sinngemäss jedes andere nicht entlastete Absperrorgan angeordnet werden. 



   Durch disse Anordnung wird auch erreicht, dass die Turbine nicht angelassen werden kann, bevor Öldruck vorhanden ist, d. h. bevor Öl auf die Lager gepumpt ist.

 turbines, which is illustrated schematically in the drawing.



   The starting device consists of the main shut-off valve a and the control valve <?, Both moved by pressure pistons. If the permissible speed is exceeded, the main shut-off valve is closed by the safety controller or for the purpose of sudden shutdown by hand using hydraulic fluid. The control valve is used for starting.



   The invention consists in the fact that the main shut-off valve cannot be opened before the control valve c is closed, for the purpose of shutting down the turbine before each sudden-

 EMI1.3
 A loaded valve a cannot be opened by the oil pressure. Only when the regulating valve is closed is the steam flowing through the auxiliary valve accumulated in space d, thereby achieving pressure equalization on both sides of valve a. The latter can now open and the turbine can be started from the control valve.



   Instead of valve a, any other non-relieved shut-off element can be arranged.



   This arrangement also ensures that the turbine cannot be started until there is oil pressure, i.e. H. before oil is pumped to the bearings.

Claims (1)

PATENT-ANSPRUCH : Anlassvorrichtung für Dampfturbinen, dadurch gekennzeichnet, dass das nicht entlastete Hauptabsperrorgan erst geöffnet werden kann, sobald das Regelventil geschlossen ist und durch Anstauung des Dampfes hinter dem Hauptabsperrorgan letzteres entlastet ist, um hierauf die Turbine mittels des Regelventiles anlassen zu können. EMI1.4 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Starting device for steam turbines, characterized in that the non-relieved main shut-off device can only be opened as soon as the control valve is closed and the latter is relieved by the accumulation of steam behind the main shut-off device, so that the turbine can then be started by means of the control valve.
