Description

Bei der Abdichtung von Stopfbuchsen, Hähnen, Ventilen u. dgl. ist es bekannt, den Dichtungsflächen Schmiermittel unter Druck zuzuführen.When sealing stuffing boxes, taps, valves and the like, it is known to use the Supply lubricant under pressure to sealing surfaces.

Gegenstand der Erfindung ist ein Hochdruck-Wasserzugschieber, auf welchen die bei hin und her gehenden Maschinenelementen an sich bekannte Dichtungsart insofern übertragen wird, als das von außen den Dichtungsflächen unter Druck zugeführte Schmiermittel an Dichtungseinsätze gelangt, welche an ihrem äußeren Umfange je mit einer Eindrehung versehen sind, in die ein das Schiebergehäuse seitlich durchsetzendes Schmierloch mündet, durch das das Schmiermittel eingepreßt wird und nun von dieser Eindrehung durch mehrere Schmierlöcher an die Dichtungsflächen gelangt.The invention relates to a high-pressure water slide valve on which the at reciprocating machine elements so far transferred known type of seal than the lubricant supplied from the outside under pressure to the sealing surfaces reaches sealing inserts, each with a recess on its outer circumference are provided, in which a laterally penetrating the valve housing lubrication hole opens, through which the lubricant is pressed and now from this turning reaches the sealing surfaces through several lubrication holes.

Der wesentlichste Vorteil des Erfindungsgegenstandes besteht darin, daß das öffnen und Schließen namentlich größerer, z. B. bei Wasserwerken gebräuchlichen Hochdruck-Wasserzugschieber wesentlich erleichtert wird. Bisher war bei diesen zufolge des hohen einseitigen Wasserdrucks die Bewegung der Schieber sehr erschwert, so daß darunter nicht nur der Bewegungsmechanismus der Schieberspindel, sondern auch die Dichtungsflächen selbst zu leiden hatten, in welche sich sehr bald Undichtigkeiten hervorrufende Riefen einarbeiteten.The main advantage of the subject matter of the invention is that it can open and closing especially larger ones, e.g. B. high-pressure water slide valves commonly used in waterworks is made much easier. So far, due to the high one-sided water pressure, the movement of these was the Slide very difficult, so that not only the movement mechanism of the slide spindle, but also the sealing surfaces themselves had to suffer very soon worked in grooves causing leaks.

Auf der Zeichnung ist der Erfmdungsgegenstand in einer Ausführungsform beispielsweise dargestellt, und zwar zeigtThe subject of the invention is shown in one embodiment in the drawing, for example shown, namely shows

Abb. ι einen Längsschnitt nach der Linie A-A der Abb. 2 undFig. Ι a longitudinal section along the line AA of Fig. 2 and

Abb. 2 einen Längsschnitt nach der Linie B-B der Abb. 1.Fig. 2 shows a longitudinal section along the line BB in Fig. 1.

Die metallenen Dichtungseinsätze α sind je mit einer Eindrehung b am äußeren Umfange versehen, in welche ein das Schiebergehäuse c seitlich durchsetzendes Schmierloch d mündet. Von der Eindrehung d aus führen eine Anzahl quer zu dieser liegende kleinere Schmierlöcher e an die Dichtungsflächen f und münden in Schmiernuten e', die sowohl an den Dichtungsflächen der Einsätze« als auch an denen des Schiebers g vorgesehen sind. Vor die Schmierleitung d ist zweckmäßig ein Rückschlagventil h angeordnet, welches den Zurücktritt des Schmiermittels verhindert.The metal sealing inserts α are each provided with a recess b on the outer circumference, into which a lubrication hole d laterally penetrates the slide valve housing c . From the recess d , a number of smaller lubrication holes e lying transversely to this lead to the sealing surfaces f and open into lubrication grooves e ' which are provided both on the sealing surfaces of the inserts and on those of the slide g . A check valve h , which prevents the return of the lubricant, is expediently arranged upstream of the lubrication line d.
