Um die Bewegung des Ventils oder Hahnes herbeizuführen, versetzt die Steuerstange A (Fig. ι bis 7) durch Druck oder Zug den Steuerhebel B in Drehung um den Winkel b Q c, wodurch sich innerhalb des Winkels a Q c die gekrümmte Seite d des Steuerhebels B auf der Seite e des Ventilhebels C abrollt, so dafs letzterer um den Winkel a Mb sich drehen mufs und beim Hingang der Steuerstange A ein Oeffnen, beim Rückgang ein Schliefsen des Ventils oder Hahnes zwangläufig herbeigeführt wird dadurch, dafs der Theil f des Ventilhebels C an dem curvenförmigen Theile g des Steuerhebels B gleiten mufs, während die Seiten d und e der beiden Hebel sich fortwährend berühren.In order to bring about the movement of the valve or cock, the control rod A (Fig. Ι to 7) puts the control lever B in rotation by the angle b Q c by pushing or pulling, whereby the curved side d of the control lever is within the angle a Q c B unrolls on side e of valve lever C , so that the latter has to rotate through the angle a Mb and when the control rod A enters, the valve or cock is forced to close, because part f of valve lever C is inevitably brought about must slide on the curved part g of the control lever B , while the sides d and e of the two levers continually touch each other.
Fig. ι und 4 zeigen Ausführungsformen des Hebelsystems, je nachdem der Ventilhebel C als Winkelhebel oder als gerader Hebel ausgebildet ist.Fig. Ι and 4 show embodiments of the lever system, depending on whether the valve lever C is designed as an angle lever or as a straight lever.
Fig. 2 und 5 zeigen die Hebelstellung bei maximalem Ventilhube.2 and 5 show the lever position at maximum valve lift.
Fig. 3 und 6 zeigen die Hebel während der Schlufsperiode.Figures 3 and 6 show the levers during the closing period.
Fig. 7 zeigt die Hebel für Hahnsteuerung.Fig. 7 shows the lever for cock control.
Die Vorrichtung R (Fig. 1, 4 und 7), welche Fig. 8 und 9 im Schnitt zeigen, hat den Zweck, durch das Nachgeben der Plattenfedern S einer Beschädigung des Hebelsystems vorzubeugen, indem diese Vorrichtung eine Längenänderung der Ventilspindel oder Steuerstange gestattet, wenn ein harter Körper durch Zufall zwischen Ventil und Ventilsitz bezw. zwischen die steuernden Kanten der Hahnsteuerung gelangt sein sollte.The device R (Fig. 1, 4 and 7), which Fig. 8 and 9 show in section, has the purpose of preventing damage to the lever system by the yielding of the plate springs S by allowing a change in length of the valve spindle or control rod, if a hard body by accident between valve and valve seat BEZW. should have got between the controlling edges of the tap control.
