Abstract
Description
Die Erfindung betrifft einen Schieber für ein Schieberventil und betrifft weiter ein Verfahren und ein Formwerkzeug zum Herstellen eines solchen Schiebers.The invention relates to a slide for a slide valve and further relates to a method and a mold for manufacturing of such a slide.
Unter Schieberventilen werden im Folgenden ganz allgemein solche Ventile verstanden, bei denen eine Verbindung dadurch freigegeben wird, dass eine an einem Schieber ausgebildete Steuerkante eine in der Wandung eines den Schieber führenden Gehäuses ausgebildete Ausnehmung überfährt und dadurch einen Flüssigkeitsdurchlass freigibt.Under slide valves are in The following generally understood such valves in which one Connection is released by one on a slider trained control edge one in the wall of a slide leading housing trained recess runs over and thereby a liquid passage releases.
Ein Problem solcher Schieberventile liegt darin, dass beim Überfahren der Ausnehmung durch die Steuerkante miteinander verbundenen Leitungen plötzlich hohe Druckänderungen auftreten, was zu Schwingungen des Ventils und/oder in dem betroffenen System führen kann.A problem with such slide valves is that when driving over the recess through the control edge interconnected lines suddenly high pressure changes occur, causing vibration of the valve and / or in the affected System can.
Um die plötzlichen Druckschwankungen zu vermindern, ist es bekannt, eine oder mehrere von der Steuerkante ausgehende Vorsteuerkerben im Schieber auszubilden, wodurch die durch den Schieber gesteuerte Querschnittsänderung weniger abrupt verläuft. Mit solchen Kerben konnte die Problematik plötzlicher Druckänderung und dadurch bedingter Schwingungen nur begrenzt gelöst werden, da ihre Form keine hinreichend kleinen Querschnittsänderungsgradienten zuließ.To the sudden pressure fluctuations to decrease, it is known to reduce one or more of the control edge to form outgoing pilot notches in the slide valve, which makes the Cross-sectional change controlled by the slide is less abrupt. With such notches could solve the problem of sudden pressure changes and the resulting vibrations can only be solved to a limited extent, because their shape does not have sufficiently small cross-sectional change gradients allowed.
Der Erfindung liegt die Aufgabe zugrunde, ein Schieberventil derart auszubilden, dass unerwünschte plötzliche hohe Querschnittsänderung mit entsprechenden nachteiligen Druckverläufen beim Freigeben einer Fluidverbindung vermieden werden.The invention is based on the object Form slide valve so that undesirable sudden high cross-sectional change with corresponding disadvantageous pressure profiles when releasing a fluid connection be avoided.
Diese Aufgabe wird mit einem Schieber für ein Schieberventil gelöst, welcher Schieber einen in einer Gehäusebohrung führbaren Abschnitt, beispielsweise mit größerem, gleichem oder kleinerem Durchmesser aufweist, der axial in einer Steuerkante endet, über die er in einen Abschnitt mit kleinerem Durchmesser übergeht, wobei von der Steuerkante eine in der Außenfläche des Abschnitts mit größerem Durchmesser ausgebildete, sich zu einer Spitze verjüngende Kerbe ausgeht.This task is done with a slider for a Slide valve released, which slider a feasible in a housing bore Section, for example with a larger, the same or has a smaller diameter that ends axially in a control edge over which it merges into a section with a smaller diameter, one of the control edge in the outer surface of the Section with a larger diameter trained notch tapering to a point.
Mit Vorteil nimmt die Tiefe der Kerbe mit zunehmendem Abstand von der Steuerkante ab.The depth of the notch advantageously takes with increasing distance from the control edge.
Bevorzugt hat die Kerbe dreieckigen Querschnitt.Preferably the notch is triangular Cross-section.
Erfindungsgemäß wird weiter ein Verfahren zum Herstellen eines Schiebers mit einem oder mehreren der vorstehenden Merkmale geschaffen, das folgende Schritte enthält:
- – Bereitstellen eines ohne die Kerbe ausgebildeten Schieberrohlings,
- – Einlegen des Schieberrohlings in ein Formwerkzeug, beispielsweise zwischen zwei Formwerkzeughälften, die einen entsprechend dem Rohling ausgebildeten Formhohlraum bilden, wobei eines der Formwerkzeuge mit einer komplementär zu der Kerbe geformten Erhebung ausgebildet ist, und
- – Einprägen der Kerbe in den Schieberrohling beispielsweise durch Aufeinanderzubewegen der Formwerkzeughälften.
- Provision of a slide blank designed without the notch,
- - Inserting the slide blank in a mold, for example between two mold halves, which form a mold cavity designed in accordance with the blank, one of the molds being designed with an elevation complementarily shaped to the notch, and
- - Emboss the notch in the slide blank, for example, by moving the mold halves together.
Vorteilhafterweise werden die Außenflächen des mit der Kerbe versehenen Formrohlings fertig bearbeitet.The outer surfaces of the finished with the notched blank.
Erfindungsgemäß wird weiter ein Formwerkzeug zum Herstellen eines erfindungsgemäßen Schiebers geschaffen, das eine wenigstens einem Teilbereich des Umfangs des Schiebers entsprechend komplementär geformte Formausnehmung enthält, die mit einer komplementär zu der Kerbe geformten Erhebung ausgebildet ist.According to the invention, a molding tool is also used created for producing a slide according to the invention, the an at least a portion of the circumference of the slide accordingly complementary contains molded recess, the one with a complementary is formed to the notch-shaped elevation.
Bevorzugt weist eine radiale Stirnfläche, von der die Erhebung ausgeht, einen axialen Freischnitt zur Aufnahme von beim Prägen der Kerbe verdrängtem Material auf.Preferably has a radial end face from which the survey assumes an axial free cut to accommodate while embossing the notch displaced Material on.
Die Erfindung wird im Folgenden anhand eines nicht beschränkenden Beispiels mit weiteren Einzelheiten erläutert.The invention is explained below one non-limiting Example explained with further details.
