  Vorrichtung zum Regeln von Dampfturbinen, deren Treibmittel Druckschwankungen unterworfen ist. 



   Die Erfindung betrifft eine Vorrichtung zum Regeln von Dampfturbinen, deren Treibmittel Druckschwankungen unterworfen ist. Sie besteht darin, dass die   Dampfzuführung   der Turbine von dem vor den   Düsen   einer Stufe der Turbine, also hinter dem vom Geschwindigkeits-   regler zu stellenden Dampfeinlassorgane,   jeweils sich einstellenden Dampfdrucke beeinflusst wird. 



   Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung veranschaulicht. 



   Der Raum a   vor den Düsen   einer Stufe einer Dampfturbine steht durch ein Rohr b mit der einen Seite eines Kraftkolbens c in Verbindung, an dessen anderer von der Atmosphäre beeinflussten Seite eine Feder   d   angreift. Die durch die Schwankungen des Dampfdruckes in dem Raume a hervorgerufenen Bewegungen des Kraftkolbens c werden unter Zwischenwirkung einer Feder e und einer Flüssigkeitsbremse f auf einen Steuerschieber g überragen, welcher die   Druekmittelzutuhr   zu dem mit dem   Dampfeinlässorgan   h fest verbundenen federbelasteten Kraftkolben t regelt.

   Eine Verstellung des Ventils   h   kann ferner auch, wenn   gewünscht, unabhängig   von der Dampfspannung vor den Düsen durch den Fliehkraftregler k unter Vermittlung der   Hilfsmaschine !   und des mit dem Reglergestänge verbundenen Kolbens m bewerkstelligt werden. 



   Die Wirkungsweise ist folgende : Die kleineien Bewegungen des Kolbens c werden von der Feder   e und   die plötzlich auftretenden Stösse von der Flüssigkeitsbremse f aufgenommen, so   dass nur   das mittlere Mass der in der Kammer a eintretenden Druckschwankungen auf das figent-   liche Regelungsorgan übertragen wird.   



   Wenn nun beispielsweise der Druck vor den Düsen z. B.   infolge Veränderungen der Be-   lastung der Turbine oder des Druckes bzw. der Menge des verfügbaren Abdampfes um einen 
 EMI1.1 
 il es   Kraftkolbens c nach rechts statt.   



   Die neue Regelungsvorrichtung ist sowohl bei Abdampfturbinen als auch bei Frischdampf- 
 EMI1.2 
 betätigt wird.

  Device for controlling steam turbines whose propellant is subject to pressure fluctuations.



   The invention relates to a device for controlling steam turbines, the propellant of which is subject to pressure fluctuations. It consists in the fact that the steam supply to the turbine is influenced by the steam pressure that is set in front of the nozzles of a stage of the turbine, that is, behind the steam inlet element to be set by the speed regulator.



   An embodiment of the subject matter of the invention is illustrated in the drawing.



   The space a in front of the nozzles of a stage of a steam turbine is connected by a pipe b to one side of a power piston c, on the other side of which a spring d engages, which is influenced by the atmosphere. The movements of the power piston c caused by the fluctuations in the vapor pressure in the space a are projected, with the action of a spring e and a fluid brake f, onto a control slide g, which regulates the pressure medium supply to the spring-loaded power piston t, which is firmly connected to the steam inlet element h.

   An adjustment of the valve h can also, if desired, independently of the steam tension in front of the nozzles by the centrifugal governor k through the intermediary of the auxiliary machine! and the piston m connected to the governor linkage.



   The mode of operation is as follows: The small movements of the piston c are absorbed by the spring e and the suddenly occurring shocks are absorbed by the fluid brake f, so that only the mean amount of the pressure fluctuations occurring in the chamber a is transferred to the control element in the figure.



   If, for example, the pressure in front of the nozzles z. B. as a result of changes in the load on the turbine or the pressure or the amount of available exhaust steam by one
 EMI1.1
 il there power piston c to the right instead.



   The new control device is applicable to both exhaust steam turbines and live steam
 EMI1.2
 is operated.
