Description

Vorrichtung zur Gleichhaltung des Entnahmedampfdruckes bei Anzapfdampfmaschinen. Die Erfindung betrifft eine Vorrichtung zur Gleichhaltung des Entnahmedampfdruckes bei Anzapfdampfmaschinen, bei welchen durch den Fliehkraftregler das FrischdampfeinlaB-organ und das frberströmventil im gleichen und durch den Entnahmedruckregler im entgegengesetzten Sinne betätigt werden. Sie besteht darin, daß ein in der Entnahmeleitung vorgesehenes Frischdampfzusatzventil nur dem Einfiuß des Entnahmedruckreglers untersteht. Hierdurch wird in vorteilhafter Weise erreicht, daß auch beim Stillsetzen der Anzapf= dampfmaschine durch entsprechenden Zusatz von Frischdampf in der Entnahmeleitung eine Gleichhaltung des Dampfdruckes ohne nachteilige Beeinflussung durch den Fliehkraftregler gewährleistet wird.Device for keeping the extraction steam pressure equal in extraction steam machines. The invention relates to a device for keeping the withdrawal steam pressure equal with bleed steam machines, in which the main steam inlet organ is controlled by the centrifugal governor and the overflow valve in the same and through the extraction pressure regulator in the opposite Senses are activated. It consists in the fact that one is provided in the extraction line The main steam valve is only subject to the influence of the extraction pressure regulator. Through this is achieved in an advantageous manner that even when the tapping = steam engine is shut down by adding live steam in the extraction line, equality is achieved the vapor pressure is guaranteed without any adverse influence from the centrifugal governor will.

Der Erfindungsgegenstand ist in der Zeichnung in beispielsweiser Ausführung veranschaulicht. Hierin bezeichnet a eine Dampfturbine, bei welcher ein Teil des Dampfes, nachdem er in dem Hochdruckteil Arbeit geleistet hat, an der Entnahmestelle b zu Heiz- oder Kochzwecken abgezapft wird. Zwischen dem Niederdruckteil und der Dampfentnahmestelle ist ein überströmventil c vorgesehen. Die Frischdampfzufuhr zur Dampfturbine wird durch das Frischdampfventil d eingestellt. Die beiden Ventile c und d werden in an sich bekannter Weise von dem Fliehkraftregler e im gleichen und von dem Entnahmedruckregler f im entgegengesetzten Sinne betätigt.The subject of the invention is shown in the drawing in an exemplary embodiment illustrated. Here, a denotes a steam turbine in which part of the Steam, after he has done work in the high-pressure part, at the extraction point b is tapped for heating or cooking purposes. Between the low pressure part and the An overflow valve c is provided for the steam extraction point. The live steam supply to the steam turbine is set by the main steam valve d. The two valves c and d are in a manner known per se from the centrifugal governor e in the same and operated in the opposite sense by the extraction pressure regulator f.

Es ist ferner ein Frischdampfzusatzventilg vorgesehen, welches, falls der Bedarf an Verbrauchsdampf in der Heiz- oder Kochleitung den verfügbaren Entnahmedampf übersteigt, der Anzapfleitung selbsttätig Frischdampf zuführt. Die Verstellung des Frischdampfeinlaßorgans d und des trberströmventils c in Abhängigkeit von den Bewegungen des Fliehkraftreglers e und des Druckreglers f erfolgt unter Zwischenwirkung von Hilfsmaschinen h, i. Für das Frischdampfzusatzventil g ist eine Hilfsmaschine k vorgesehen. Die Einrichtung ist _nun so getroffen, daß bei Druckschwankungen an fier Entnahmestelle b unter dem Einfluß des Druckreglers f unter Zwischenwirkung der Hilfsmaschinen h, i zunächst die Ventile c, d im entgegengesetzten Sinne betätigt werden. Erst wenn bei steigendem Entnahmedampfver= brauch das Ventil c geschlossen ist, wirkt der Druckregler f auch auf die Hilfsmaschine k ein und öffnet das Frischdampfzusatzventil g. Zu diesem Zweck ist zwischen dem Gestänge i des Druckreglers f und dem Gestänge m der Hilfsmaschine k ein toter Gang so eingeschaltet, daß der Druckregler f auf das Überström ventil c und das Frischdampfzusatzventil g nacheinander im entgegengesetzten Sinne einwirkt.A live steam addition valve is also provided which, if the demand for consumption steam in the heating or cooking line exceeds the available extraction steam, automatically supplies live steam to the tapping line. The adjustment of the main steam inlet element d and the overflow valve c as a function of the movements of the centrifugal regulator e and of the pressure regulator f takes place with the interaction of auxiliary machines h, i. An auxiliary machine k is provided for the live steam additional valve g. The device is now designed in such a way that, in the event of pressure fluctuations at four extraction point b, under the influence of the pressure regulator f with the interposition of the auxiliary machines h, i , the valves c, d are initially operated in the opposite direction. Only when the valve c is closed with increasing consumption of extraction steam, the pressure regulator f also acts on the auxiliary machine k and opens the live steam auxiliary valve g. For this purpose, a dead gear is switched on between the linkage i of the pressure regulator f and the linkage m of the auxiliary machine k so that the pressure regulator f acts on the overflow valve c and the live steam auxiliary valve g one after the other in the opposite sense.
