Die Erfindung betrifft eine Regelungsvorrichtung für Gegendruckmaschinen, bei welchen die Dampfzufuhr durch einen Drehzahlregler beeinflußt wird. Sie besteht darin, daß in die Abdampfleitung zwei an sich bekannte durch einen Druckregler nacheinander betätigte Ventile für Frischdampfeinlaß und Abdampfauslaß eingebaut sind, die der Wirkung des Drehzahlreglers der Gegendruckmaschinen ίο derart unterstellt sind, daß trotz wechselnder Belastung den Abdampfverbrauchsstellen dauernd die gleiche Abdampfmenge zufließt.The invention relates to a control device for counter-pressure machines, in which the steam supply is influenced by a speed controller. It consists in that in the exhaust line two known per se actuated one after the other by a pressure regulator Valves for main steam inlet and exhaust steam outlet are built in, the effect of the speed regulator of the counter-pressure machines ίο are so subordinated that despite changing Load, the same amount of evaporation flows continuously to the evaporation consumption points.
Der Gegenstand der Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel veranschaulicht. The object of the invention is illustrated in the drawing in an exemplary embodiment.
Hierin bezeichnet α eine Gegendruckturbine, deren Abdampf durch die Leitung b irgendwelchen Dampfverbrauchsstellen zu Heiz- oder Kochzwecken zugeführt wird. Das Steuerorgan des Frischdampfeinlaßventils c wird unter Vermittlung einer Hebelübersetzung durch einen Fliehkraftregler d beeinflußt, welcher in bekannter Weise bei Belastungsschwankungen in Tätigkeit tritt. Der Drehzahlregler d greift ferner im Punkt e an einem Hebel f an, welcher außerdem noch unter dem Einfluß eines im Punkt r angreifenden Abdampfdruckreglers g steht. Dieser Hebel f bewirkt durch das in dem Punkt h angreifende Gestänge i .30 unter Zwischenwirkung eines Ölsteuerschiebers k und eines Kraftkolbens I die Verstellung eines zweiten Hebels m. Am Hebel m sind in den Punkten n, 0 die Gestänge von zwei in das Abdampf rohr & mündenden Ventilen f, q angelenkt. Und zwar soll das Ventil f der Ab- dampfleitung gedrosselten Frischdampf zuführen, wenn der Abdampf der Gegendruckmaschine nicht ausreicht, während das Ventil q bei geringem Abdampf bedarf einen Teil des Abdampfes ins Freie oder in den Kondensator abblasen läßt. Der Hebel μ wirkt als ein- oder zweiarmiger Hebel, je nachdem das Gestänge i aufwärts oder abwärts bewegt wird.Here, α denotes a back pressure turbine, the exhaust steam of which is fed through line b to any steam consumption points for heating or cooking purposes. The control element of the live steam inlet valve c is influenced by means of a lever transmission by a centrifugal governor d , which comes into action in a known manner in the event of load fluctuations. The speed controller d also acts on a lever f at point e , which is also under the influence of an exhaust pressure regulator g that acts at point r . This lever f effects the adjustment of a second lever m through the linkage i .30 acting at point h with the interplay of an oil control slide k and a power piston I. On the lever m , the linkages of two are in the exhaust steam pipe & at points n, 0 opening valves f, q articulated. The valve f is intended to supply throttled live steam to the exhaust line if the exhaust steam from the counterpressure machine is insufficient, while valve q allows part of the exhaust steam to be blown off into the open air or into the condenser when there is little exhaust steam required. The lever μ acts as a one or two-armed lever, depending on whether the linkage i is moved up or down.
Angenommen, der Abdampfbedarf' in den Verbrauchsstellen sei gleichbleibend, während die Belastung der Maschine z. B. abnimmt, so schwingt der Hebel f unter Einfluß des Fliehkraftreglers d um den Punkt /. Das Frischdampfeinlaßorgan c wird hierdurch um einen gewissen Betrag geschlossen und gleichzeitig das Frischdampfzusatzventil -p geöffnet, so daß der Druck in der Abdampfleitung b trotz verminderter Energiezufuhr zur Turbine gleichbleibend erhalten wird. ' Bei steigender Belastung wird in entsprechender Weise das Einlaßorgan c geöffnet, das Reduzierventil p geschlossen bzw. das Abblaseventil q geöffnet.Assuming that the evaporation requirement 'in the consumption points is constant, while the load on the machine z. B. decreases, the lever f swings under the influence of the governor d around the point /. The live steam inlet element c is thereby closed by a certain amount and at the same time the live steam addition valve -p is opened, so that the pressure in the exhaust steam line b is kept constant despite the reduced energy supply to the turbine. When the load increases, the inlet member c is opened, the reducing valve p is closed and the relief valve q is opened in a corresponding manner.
Stellt sich jedoch infolge Zuschaltung von Dampfverbrauchsstellen ein niederer Dampfdruck in der Abdampfleitung ein, so wird der Hebel f durch den Druckregler g um den Punkt e gedreht. Hierdurch wird das Reduzierventil j> um einen gewissen Betrag geöffnet, ohne daß dabei das Frischdampfeinlaßorgan c irgendwelche Verstellung erfährt. Steigt nunIf, however, a low steam pressure arises in the exhaust line as a result of the connection of steam consumption points, the lever f is rotated by the pressure regulator g about point e. As a result, the reducing valve j> is opened by a certain amount without the live steam inlet element c being adjusted in any way. Now increases
bei gleichbleibender Belastung der Turbine der Abdampfdruck infolge Abschaltung von Dampfverbrauchsstellen, so wird in entsprechender Weise ohne: Veränderung der Energiezufuhr zur Gegendruckturbine der Abdampfdruck durch Schließen des Ventils p bzw. öffnen des Ventils q auf das ursprüngliche Maß zurückgeführt.with constant load on the turbine, the exhaust pressure due to the shutdown of steam consumption points, the exhaust pressure is returned to the original level in a corresponding manner without: changing the energy supply to the back pressure turbine by closing valve p or opening valve q.
