Description

Der Erfiudungsgegenstand betrifft eine Hubanzeigevorrichtung für Kolbenschieberventile. The subject matter of the invention relates to a Stroke indicator for piston slide valves.

Allen Kolbenschieberventilen haftet der Mangel an, daß bei denselben der Beginn des Öffnens und Schließens des Kolbenschiebers äußerlich nicht sichtbar ist.All piston slide valves have the defect that they begin with the opening and closing of the piston valve is not externally visible.

Es ist notwendig, z. B. bei chemischen Prozessen, bei welchen eine genau bestimmteIt is necessary e.g. B. in chemical processes in which a precisely defined

ίο Durchflußmenge eingehalten, werden muß, den jeweiligen Ventilhub, d.h. die effektive öffnung des Kolbenschiebers genau meßbar einstellen und ablesen zu können. Bisher war dies nur schätzungsweise möglich, denn der wirksame Kolbenschieberhub beginnt erst mit dem Augenblick, wo die Kolbenunterkante den unteren Dichtungsring verläßt; die Ventilspindel muß um eine Ringbreite gehoben werden, bevor das Ventil zu öffnen beginnt.ίο the flow rate must be adhered to, the respective valve lift, i.e. the effective opening of the piston valve, can be precisely measured to be able to set and read. So far this has only been possible because of the effective piston slide stroke only begins at the moment when the lower edge of the piston leaves the lower sealing ring; the valve spindle must be raised by a ring width before the valve starts to open.

Der vorliegende Erfindungsgeg;enstand schafft .durch die besondere Gestaltung von Spindel und Spindelmutter die Möglichkeit, an der Höhenlage des Gewindes gegenüber der Mutter ohne weiteres den Öffnungsgrad des Schiebers zu erkennen.The present invention ; Due to the special design of the spindle and spindle nut, the result creates the possibility of easily recognizing the degree of opening of the slide from the height of the thread opposite the nut.

In der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigen Abb. 1 ein Kolbenschieberventil in geschlossenem Zustand. Abb. 2 zeigt das Ventil in zum Teil geöffnetem Zustand. "The subject of the invention is shown in the drawing, namely Fig. 1 a piston valve in the closed state. Fig. 2 shows the valve in part open state. "

Der Kolbenschieber 2 hat den unteren Dichtungsring ι verlassen und ist um ein Stück gehoben worden. Dieses Stück ist am Ventilaufsatz 4 und an der Spindel 3 durch die Eindrehung 6 kenntlich gemacht, denn die Spindelkante β ist um dasselbe Stück, den effektiven Hub, von der Oberkanten der Spindelimutter 5 entfernt, um das sich die Kolbenunterkante C von der Oberkante d des unteren Dichtungsringes I entfernt hat.The piston slide 2 has left the lower sealing ring and has been lifted a little. This piece is identified on the valve attachment 4 and on the spindle 3 by the notch 6, because the spindle edge β is the same distance, the effective stroke, away from the upper edge of the spindle nut 5 by which the piston lower edge C moves from the upper edge d of the lower sealing ring I has removed.
