Description
Hierdurch wird erreicht, daß beim Bewegen des Kolbens .ein Lochrand beim Vorbeigleiten an der unteren Packung nicht an einer Stelle schabt und die Packung ungleich abnutzt bzw. die Dichtigkeit herabsetzt, sondern dah jeweils eine volle Zylinderfläche des Kolbens durch die Packung gleitet und daß, soweit eine Abnutzung eintritt, dieselbe gleichmäßig auf dem ganzen Umfang der Packung auftritt.This ensures that when moving the piston .ein hole edge when sliding past the lower pack, do not scrape in one place and the pack wears out unevenly or reduces the tightness, but then a full one Cylinder surface of the piston slides through the packing and that, as far as wear occurs, it occurs evenly over the whole circumference of the packing.
Weiter kann etwaiges zwischen Kolben und Stopfbüchsen aus der Packung sich ansammelndes Geschabe, selbst Schlamm aus einem Kessel, in der abgesetzten Zylinderfläche des Kolbens abgestoßen werden, was sonst beim Fehlen dieser Absatzfläche zu einem Verreiben und Klemmen des Kolbens Anlaß geben würde.Anything can also be removed from the packing between the piston and the stuffing box accumulating scrap, even sludge from a kettle, in the settled The cylinder surface of the piston is repelled, which would otherwise occur in the absence of this shoulder surface would give rise to rubbing and jamming of the piston.
Die zugleich verringerte Anlagefläche des Kolbens an den Stopfbüchsen dürfte auch die Bewegung des ersteren erleichtern.The reduced contact surface of the piston on the stuffing boxes should also facilitate the movement of the former.
Endlich sichert die abgesetzte Zylinderfläche des Kolbens in geöffnetem Zustande den Durchlaß auch in dem Falle, daß der Kolben mit seinen Öffnungen gegenüber den öffnungen der Stopfbüchse sich verdreht hat, wodurch bei vollem Zylinder die öffnung überdeckt und der Durchfluß unterbunden sein würde. Die letzterwähnten Vorteile können erfindungsgemäß auch durch eine abgesetzte Zylinderfläche der Stopfbüchse unterstützt werden.Finally, the stepped cylinder surface secures the piston in the open Establish the passage also in the event that the piston with its openings opposite has twisted the openings of the stuffing box, which causes the Covered opening and the flow would be blocked. The last mentioned advantages can according to the invention also by a stepped cylinder surface of the stuffing box get supported.
Die Erfindung ist in einem Ausführungsbeispiel dargestellt. In dem Gehäuse a mit Eintritt b und Austritt c ist ein Kolben d eingesetzt, der durch Packungen e und Stopfbüchsen gedichtet wird, und zwar durch die büchse f mit Durchflußöffnungen und durch die Stopfbüchse g, die zugleich zu einer Abdeckung des Gehäuses mit Spindelführung und Hohlraum für den Kolben ausgebildet ist.The invention is illustrated in one embodiment. By doing Housing a with inlet b and outlet c, a piston d is inserted through packings e and stuffing boxes is sealed, through the sleeve f with flow openings and through the stuffing box g, which also serves to cover the housing with a spindle guide and a cavity is formed for the piston.
In gezeichneter geöffneter Darstellung besitzt der Kolben d eine angesetzte Mantelfläche bzw. Ringkammer h, während in dem schwächeren Teil des Kolbens d die Durchflußöffnungen i vorgesehen sind.In the drawn, open representation, the piston d has an attached Outer surface or annular chamber h, while in the weaker part of the piston d the Flow openings i are provided.
Um den Schieber zu schließen, wird mittels der Spindel der Kolben in das Ventilgehäuse hineingedrückt. wobei die abgesetzte Fläche h über die untere Packung e hinweggleitet, so daß in geschlossenem Zustande der zylindrische Kolben die Bohrung zwischen den Packungen e bzw. Stopfbüchse i ausfüllt.In order to close the slide, the piston is activated by means of the spindle pressed into the valve housing. where the stepped area h over the lower Pack e slides away so that in the closed state the cylindrical piston fills the hole between the packings e or the stuffing box i.
Die Eindrehung hl der Stopfbüchse f unterstützt diejenige des Kolbens.The turning hl of the stuffing box f supports that of the piston.
