Description

Für die Zwischendampfentnahme bei Dampfkraftmaschinen sind Regelvorrichtungen bekannt, welche in der Verbindungsleitung zwischen Hoch- und Niederdruckzylinder angeordnet werden. Bei diesen Regelvorrichtungen wird ein mit Federdruck belastetes Ventil oder Schieber durch den Aufnehmerdruck mehr oder weniger gehoben, so daß der für die Heizung nicht benötigte Zwischendampf in den Niederdruckzylinder gelangen kann, um hier weitere Arbeit zu leisten. Bei diesen Vorrichtungen ist die Heizleistung mit dem Aufnehmer verbunden. Der Aufnehmerdruck ist aber Schwankungen unterworfen, welche auf die Heizleitung übertragen werden. Ist in der Heizleitung kein zweites Regelorgan angeordnet, so überschreitet zuweilen der Heizdruck und damit die Heiztemperatur die erwünschte Höhe.Control devices are used for the extraction of intermediate steam in steam engines known which in the connecting line between high and low pressure cylinder to be ordered. In these regulating devices, a spring pressure is applied The valve or slide is more or less lifted by the sensor pressure, so that the intermediate steam not required for heating can get into the low pressure cylinder to do further work here. In these devices, the Heating power connected to the transducer. However, the transducer pressure is fluctuations which are transferred to the heating cable. Is in the heating cable if no second regulating element is arranged, the heating pressure sometimes exceeds and thus the heating temperature the desired level.

ao Durch die Druckschwankungen im Aufnehmer werden ferner die regelnden Teile in eine auf und ab gehende Bewegung versetzt, durch welche Stöße und Schläge hervorgerufen werden.ao Due to the pressure fluctuations in the transducer, the regulating parts are also converted into a up and down moving movement, caused by bumps and blows will.

Die Erfindung vermeidet diese Nachteile dadurch, daß der Dampfzutritt zum Niederdruckzylinder und zur Heizleitung durch den in der Heizleitung herrschenden Druck mittels zweier miteinander in Verbindung stehender Absperrorgane geregelt wird.The invention avoids these disadvantages in that the steam access to the low-pressure cylinder and to the heating line by the pressure prevailing in the heating line by means of two that are connected to one another Shut-off devices is regulated.

Auf der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise dargestellt. In the drawing, the invention is shown in one embodiment, for example.

Die Abbildung veranschaulicht den senkrechten Längsschnitt.The figure illustrates the vertical longitudinal section.

In dem Gehäuse 1 sind die beiden miteinander verbundenen Schieber 2 und 3 angeordnet, welche durch die Spannkraft der Feder 4 herabgedrückt werden. Der vom Hochdruckzylinder kommende und in den Stutzen 5 tretende Dampf wird zunächst durch die Aussparung 6 vom Stutzen 7 in die Heizleitung geführt. Steigt der Druck in derselben, so schließt der Schieber 3 den Zutritt zur Heizleitung mehr ab, während der mit dem Schieber 3 verbundene Schieber 2 den Zutritt zum Stutzen 8 des Niederdruckzylinders öffnet.The two interconnected slides 2 and 3 are arranged in the housing 1, which are pressed down by the tension of the spring 4. The one from the high pressure cylinder Steam coming and entering the nozzle 5 is first passed through the recess 6 from the nozzle 7 into the heating line guided. If the pressure rises in the same, the slide 3 closes the access to the heating cable more from, while the slide 2 connected to the slide 3 opens access to the nozzle 8 of the low-pressure cylinder.

Bei Überschreitung eines bestimmten, durch die Spannung der Feder 4 regelbaren Druckes in der Heizleitung wird der Zutritt zu derselben gänzlich abgeschlossen, so daß der vom Hochdruckzylinder kommende Dampf ausschließlich zum Niederdruckzylinder geführt wird. Damit Drosselverluste möglichst vermieden werden, muß beim Ab-Schluß der Heizleitung 7 der Zutritt zum Niederdruckzylinder 8 um ein bestimmtes Maß geöffnet sein. Um dieses Maß leicht ändern zu können, sind die beiden kolbenartigen Körper 2 und 3 des Steuerorgans durch ein Distanzrohr 9 getrennt. Durch Kürzung des Distanzrohres oder durch Zwischenlagen kann die Entfernung der beiden steuernden Kanten leicht geändert werden.When a certain value is exceeded, the tension of the spring 4 can be regulated Pressure in the heating line, access to the same is completely closed, so that the steam coming from the high pressure cylinder is directed exclusively to the low pressure cylinder. With it throttle losses to be avoided as far as possible, the access to the low-pressure cylinder must be at the conclusion of the heating line 7 8 be open to a certain extent. In order to be able to change this dimension easily, the two are piston-like Body 2 and 3 of the control member separated by a spacer tube 9. By shortening the spacer tube or using intermediate layers the distance between the two controlling edges can easily be changed.

Durch die Spindel kann das Steuerorgan von Hand so weit hochgeschraubt werden, daß die Heizleitung völlig abgesperrt und der Zutritt zum Niederdruckzylinder gänzlich freigegeben wird.Through the spindle, the control element can be screwed up by hand so far that the heating cable is completely shut off and access to the low-pressure cylinder is completely released will.
