Um bei Dampfturbinen mit Regelung durch Drosselventil große Überlastungsfähigkeit zu erhalten, ohne bei normaler Belastung mit .abgedrosseltem Dampf, also unwirtschaftlich arbeiten zu müssen, führt man bekanntlich bei Überlastung der Niederdruckseite der Turbine Frischdampf zu. Die Erfindung betrifft ein für diesen Zweck geeignetes, aus Hauptventil und Zusatzventil zusammengesetztes Steuerventil in möglichst einfacher und gedrängter Anordnung.In order to increase the overload capacity in steam turbines with regulation by throttle valve obtained without with normal load with. throttled steam, so uneconomical having to work is known to result in overloading the low-pressure side of the Turbine live steam too. The invention relates to a suitable for this purpose, from Main valve and additional valve combined control valve in as simple as possible and crowded arrangement.
In beiliegender Zeichnung ist ein Ausführungsbeispiel dargestellt, α ist das Ventilgehäuse, durch dessen Deckel b mittels Stopfbüchse c die vom Regler bewegte (z. B. in steilgängigem Gewinde gedrehte) Ventilspindel d eingeführt ist, die das als entlastetes Doppelsitzventil gezeichnete Hauptventil e je nach der Umdrehungszahl mehr oder weniger hebt. In eine am Ventil e befestigte Haube i greift die Spindel/ des conachsial zum Hauptventil angeordneten Zusatzventiles g mit Spielraum in der Richtung des Ventilhubes ein, so daß das der Niederdruckseite Frischdampf zuführende Zusatzventil, gegebenenfalls entgegen der Wirkung einer schwachen Belastungsfeder h, gehoben wird, sobald das Hauptventil über seinen normalen, der normalen Belastung entsprechenden Hub hinausgehoben wird.In the attached drawings an embodiment is shown, α the valve housing, b by its lid by means of gland c the moved by the controller (z. B. rotated in steilgängigem thread) valve stem is introduced d, the subscribed as relieved double seat valve main valve e depending on the RPM more or less lifts. In a hood i attached to valve e, the spindle / of the additional valve g arranged conaxially to the main valve engages with clearance in the direction of the valve stroke, so that the additional valve supplying live steam to the low-pressure side is lifted, possibly against the action of a weak loading spring h , as soon as the main valve is lifted beyond its normal stroke corresponding to the normal load.
Wie in der Zeichnung angedeutet, kann die Spindel/mit einem Hammerkopf (Bund von ovaler oder einer ähnlichen länglichen Form) in die Haube i eingreifen, in welche er durch ein Langloch eingeführt, durch eine Feder k verhindert wird, sich aus der Haube herauszudrehen.As indicated in the drawing, the spindle / with a hammer head (collar of oval or similar elongated shape) can engage in the hood i , into which it is inserted through an elongated hole and prevented by a spring k from rotating out of the hood.
Die Verbindung mit dem Regler wird eine überaus einfache, und die Ventile und Ventilsitze lassen sich infolge ihrer conachsialen Lage sehr leicht genau ausführen. Etwaige Ungenauigkeiten werden überdies dadurch unschädlich gemacht, daß die Verbindung beider Ventile miteinander keine starre ist.The connection with the controller becomes an extremely simple one, and the valves and valve seats can be carried out very easily precisely due to their conaxial position. Any Inaccuracies are also rendered harmless by the fact that the connection both valves are not rigid with each other.
