Bei der Anordnung nach Anspruch 2 des Hauptpatentes, nach welcher der glockenförmige Ventilkörper mit Graphitmasse gefüllt ist, welche sich bei der Erwärmung gegen den Sitz hin ausdehnt und eine größere Ventilöffnung bei normalem Betriebe zuläßt, hat sich der Übelstand herausgestellt, daß die sich ausdehnende Graphitmasse bei ihrer Abkühlung jeweils nicht vollständig wieder in denIn the arrangement according to claim 2 of the main patent, according to which the bell-shaped Valve body is filled with graphite mass, which when heated against the Seat expands and allows a larger valve opening during normal operations the disadvantage turned out that the expanding graphite mass as it cools each not completely returned to the
ίο' glockenförmigen Ventilkörper zurücktritt. Die Abdichtungsfläche der Graphitmasse behält vielmehr die jeweils durch die Ausdehnung des Graphitringes erhaltene Lage nahezu bei, so daß allmählich der freie Durchgang zwisehen der Abdichtungsfiäche des Graphitringes und dem Ventilsitze mehr und mehr verengt wird.ίο 'bell-shaped valve body recedes. the Rather, the sealing surface of the graphite compound retains the respective expansion of the graphite ring obtained position almost so that gradually the free passage between the sealing surface of the graphite ring and the valve seat narrowed more and more will.
Um diesen Übelstand zu vermeiden, ist nach vorliegender Erfindung die Einrichtung derart getroffen, daß der Graphitring beim jedesmaligen Abkühlen selbsttätig wieder vollständig in den glockenförmigen Ventilkörper zurückgedrängt wird.In order to avoid this inconvenience, the device according to the present invention is such made that the graphite ring is automatically pushed back completely into the bell-shaped valve body each time it cools will.
In der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung im achsialen Längsschnitt dargestellt.In the drawing, an example embodiment of the invention is shown in axial longitudinal section shown.
Der im glockenförmigen Ventilkörper c vorgesehene Graphitring g wird von einer Unterlagsscheibe h unterstützt, die auf dem oberen glatten Teile der Spindel 0 achsial verschiebbar ist und unter dem Einflüsse einer kräftigen Druckfeder r steht, welche sich anderer seits gegen eine auf der Ventilspindel 0 sitzende Stellmutter s stützt, die zugleich auch der Feder/, welche die Öffnung des Ventiles bewirkt, als Widerlager dient.The graphite ring g provided in the bell-shaped valve body c is supported by a washer h , which is axially displaceable on the upper smooth part of the spindle 0 and is under the influence of a powerful compression spring r which, on the other hand, moves against an adjusting nut s seated on the valve spindle 0 supports, which at the same time also serves as an abutment for the spring /, which causes the valve to open.
Zieht sich nunmehr der Graphitring g nach seiner Ausdehnung wieder zusammen, so wird er durch die Feder r gleichzeitig und selbsttätig wieder vollkommen in den glockenförmigen Ventilkörper c zurückgedrängt, so daß der Zwischenraum zwischen seiner Abdichtungsfläche und dem Ventilsitze η nicht mehr verengt werden kann.If the graphite ring g contracts again after its expansion, it is simultaneously and automatically pushed back completely into the bell-shaped valve body c by the spring r , so that the space between its sealing surface and the valve seat η can no longer be narrowed.
Die Stellmutter s ermöglicht die Regelung der Spannung der Feder r. The adjusting nut s enables the tension of the spring r to be regulated.
