KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft ein Steuerungsventil mit Entlastungskammer und Hilfsventil. The present invention relates to a control valve with relief chamber and auxiliary valve.
Bei den bisherigen Ausführungsformen derartiger Steuerungsventile mit Entlastungskammer und Hilfsyentil (Servoventile) machten sich im Betriebe mehrere Schwierigkeiten geltend, besonders bei Förder- und ähnlichen Anlagen, bei denen das Servoventil das bisherige Absperrventil ersetzt und daher gleichzeitig als Absperr- und als Steuerventil dienen soll.In the previous embodiments of such control valves with a relief chamber and auxiliary valve (servo valves) several difficulties asserted themselves in the company, especially in conveyor systems and similar systems in which the servo valve replaces the previous shut-off valve replaced and therefore should serve as a shut-off and control valve at the same time.
Die Nachteile der bisherigen Ausführungsformen bestanden zunächst darin, daß es nicht möglich . war, das Steuerorgan und die notwendige Feststellspindel neu zu verpacken, ohne die ganze Dampfleitung abzusperren. Ferner wurde der Antrieb des Ventils infolge der eigenartigen Betriebsverhältnisse solcher Anlagen durch die notwendige VerwendungThe disadvantages of the previous embodiments were initially that it was not possible . was to repackage the control unit and the necessary locking spindle, without shutting off the entire steam line. Furthermore, the drive of the valve was a consequence the peculiar operating conditions of such systems due to the necessary use
■2o von nachgiebigen (federnden oder ausschaltenden) Vorrichtungen meistens nicht genügend einfach.■ 2o of flexible (resilient or disengaging) devices are mostly not sufficient simple.
Diese Nächteile werden bei der vorliegenden Erfindung zunächst dadurch beseitigt, daß die Zu- bzw. Abführung des Steuerdampfes nicht mehr direkt von dem Entlastungsraum erfolgt, sondern von einem Nebenraum bewirkt wird, der von jenem Raum in geeigneter Weise, am besten durch die entsprechend ausgebildete Ventilspindel getrennt werden kann. Durch weitere Ausbildung dieser Spindel können dann auch die übrigen der oben aufgeführten Nachteile vermieden werden. These disadvantages are eliminated in the present invention in that the The control steam is no longer supplied or discharged directly from the relief space, but is effected by an adjoining room, which is appropriately controlled by that room, am can best be separated by the appropriately designed valve spindle. By further training of this spindle can then also avoid the other disadvantages listed above.
In der Zeichnung ist als Ausführungsbeispiel ein Servoventil im Querschnitt dargestellt.In the drawing, a servo valve is shown in cross section as an exemplary embodiment.
Es besteht aus dem Gehäuse a, dessen oberer Teil mit dem Entlastungskolben b des Kegels c den vom Steuerdampf durchströmten Entlastungsraum d bildet. Dieser wird in der gezeichneten tiefsten Stellung der Feststellspindel e durch diese von dem Nebenraum f getrennt, der durch das Steuerorgan g und die Leitung h mit der Abströmseite i des Ventils in Verbindung steht. Aus der Zeichnung ist ersichtlich, daß die Verpackung der Spindel und des Steuerorgans sowie die Reinigung usw. des letzteren in der gezeichneten Stellung der Spindel bzw. des Ventils möglich ist, auch wenn das letztere unter vollem Dampfdruck steht.It consists of the housing a, the upper part of which, together with the relief piston b of the cone c, forms the relief space d through which the control steam flows. In the drawn lowest position of the locking spindle e , this is separated from the adjoining space f , which is connected to the outflow side i of the valve through the control element g and the line h. From the drawing it can be seen that the packaging of the spindle and the control member as well as the cleaning etc. of the latter is possible in the position of the spindle or the valve shown, even when the latter is under full steam pressure.
Die Erfindung ist für Ventile für gasförmige oder tropfbare Flüssigkeiten gleich gut verwendbar. The invention can be used equally well for valves for gaseous or drip liquids.
