Hintergrund der ErfindungBackground of the invention
Ein Regelventil gemäß der vorgenannten Gattung ist aus der Druckschrift
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Regelventil bereitzustellen, welches kostengünstig herstellbar ist, jedoch bei hochbelasteten Anwendungen zuverlässig funktioniert.The invention has for its object to provide a control valve, which is inexpensive to produce, but works reliably in high-load applications.
Zusammenfassung der ErfindungSummary of the invention
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass Dichtring und Dichtelement axial von einander beabstandet sind und über ein mehrteiliges Stützelement positioniert werden. Ein besonderer Vorteil dabei ist dass, das Stützelement aus einem anderen Material hergestellt sein kann, als die Dichtungen selbst. Um somit mögliche Defizite der Dichtungsmaterialien bei hohen Temperatureinflüssen auszugleichen.The object is achieved in that sealing ring and sealing element are axially spaced from each other and positioned over a multi-part support element. A particular advantage of this is that, the support member may be made of a different material than the seals themselves. Thus, to compensate for possible deficiencies of the sealing materials at high temperature influences.
In Konkretisierung der Erfindung ist es vorgeschlagen, dass das mehrteilige Stützelement ein Trägerelement und ein Federabstützelement aufweist. Das Trägerelement verbindet zum einen die beiden Bauteile Dichtring und Dichtelement miteinander, zum anderen ist das Trägerelement so konstruiert, dass es den Kraftfluss zwischen dem Dichtelement am Ventilglied und der auf das Federabstützelement einwirkenden Feder ermöglicht.In concretization of the invention, it is proposed that the multi-part support element has a carrier element and a spring support element. The carrier element connects the two components sealing ring and sealing element to each other, on the other hand, the support element is constructed so that it allows the flow of force between the sealing element on the valve member and acting on the Federabstützelement spring.
In bevorzugter Ausgestaltung sind das Trägerelement und das Federabstützelement aus verschiedenen Materialien hergestellt. Die Dichtungen sind zumeist aus PFTE (Polytetrafluorethylen) hergestellt. PTFE ist ein unverzweigtes, linear aufgebautes, teilkristallines Polymer aus Fluor und Kohlenstoff. Umgangssprachlich wird dieser Kunststoff oft mit dem Handelsnamen Teflon bezeichnet. Es zeichnet sich durch einen sehr geringen Reibungskoeffizienten aus. Die guten Reibeigenschaften behält das Material auch unter hohen Temperatureinflüssen bei. Allerdings verliert PTFE bei hohen Temperaturen seine Formstabilität. PVDF (Polyvinylidenfluorid) ist ein hochkristalliner, thermoplastischer Fluorkunststoff mit relativ ausgewogenen mechanischen Eigenschaften. Im Vergleich zum PTFE verfügt PVDF über eine deutlich bessere Steifigkeit und Druckfestigkeit auch bei hohen Temperatureinflüssen. Im Gegensatz zu PTFE weist jedoch PVDF keine guten Reibeigenschaften auf. Die Dichtungen (Dichtungsring, Dichtungselement) sowie der Federanlagefläche am Federabstützelement benötigen auf Grund ihrer dynamischen Belastungen gute Reibeigenschaften. Von daher ist es sinnvoll den Werkstoff PTFE dort zu verwenden. Da ein Regelventil jedoch auch hohen Temperatureinflüssen durch das erwärmte durchströmende Kühlwasser ausgesetzt ist, benötigt es ein Bauteil, das auch bei diesen Temperatureinflüssen formstabil bleibt. Aus diesem Grund ist das Stützelement mehrteilig ausgeführt, so dass der Anteil, welcher keine dynamisch belasteten Kontaktflächen aufweist aus einem formstabilen Werkstoff wie PVDF hergestellt ist. Das Trägerelement als Teil des Stützelements ist aus PVDF hergestellt und kann somit das Dichtelement, den Dichtring und das Federabstützelement stützten und positionieren, so dass eine einwandfrei Funktionalität des Regelventils auch bei hohen Temperatureinflüssen gewährleistet ist. Aus diesem Grund ist es vorgeschlagen, ein Regelventil mit einem mehrteiligen aus unterschiedlichen Materialien bestehenden Stützelement herzustellen, wobei sich die Materialien u.a. durch Reibeigenschaften und Formstabilität von einander unterscheiden und ergänzen sollen.In a preferred embodiment, the carrier element and the Federabstützelement are made of different materials. The seals are mostly made of PTFE (polytetrafluoroethylene). PTFE is a linear, linear, partially crystalline polymer of fluorine and carbon. Colloquially, this plastic is often referred to by the trade name Teflon. It is characterized by a very low coefficient of friction. The good friction properties also keep the material under high temperature conditions. However, PTFE loses its dimensional stability at high temperatures. PVDF (polyvinylidene fluoride) is a highly crystalline, thermoplastic fluoroplastic with relatively balanced mechanical properties. Compared to PTFE, PVDF has significantly better rigidity and pressure resistance even under high temperature conditions. However, unlike PTFE, PVDF does not have good friction properties. The seals (sealing ring, sealing element) and the spring contact surface on the spring support element require good friction properties due to their dynamic loads. Therefore, it makes sense to use the PTFE material there. However, since a control valve is also exposed to high temperature influences due to the heated through-flowing cooling water, it requires a component which remains dimensionally stable even under these temperature influences. For this reason, the support element is designed in several parts, so that the proportion which has no dynamically loaded contact surfaces made of a dimensionally stable material such as PVDF. The carrier element as part of the support element is made of PVDF and can thus support and position the sealing element, the sealing ring and the Federabstützelement, so that a proper functionality of the control valve is ensured even at high temperature influences. For this reason, it is proposed to produce a control valve with a multi-part consisting of different materials support element, wherein the materials u.a. distinguish and complement each other by frictional properties and dimensional stability.
Im weiteren sieht die Erfindung vor, dass das Trägerelement axiale Stufen aufweist, damit das Dichtelement und das Federabstützelement zumindest formschlüssig in das Trägerelement eingreifen können. Diese Stufen lassen sich insbesondere in Kunststoffmaterialien leicht herstellen. Ebenso denkbar wäre ein Baukastensystem mit vormontierten Einheiten. So könnte das aus PVDF hergestellte Trägerelement mit dem aus PTFE hergestellten Dichtungselement form-, kraft- oder stoffschlüssig verbunden sein. Ebenso wäre ein vormontierte Einheit mit einem Federabstützelement aus Metall oder vorzugsweise aus PTFE und einem mit einem form-, kraft- oder stoffschlüssig damit verbundenem Dichtring denkbar. Es wäre z.B. möglich die Dichtungen an die jeweiligen Stützelemente (Federabstützelement, Trägerelement) anzuspritzen. Daraufhin müssten die beiden Bauteile lediglich in den Zuführanschluß des Ventilgehäuses eingepasst und mit der Druckfeder gegen das Ventilglied vorgespannt werden. Durch diese Vorgehensweise können die Montagezeiten verkürzt und Einbaufehler durch die Reduktion der Einzelteile vermieden werden. Die zuvor genannten Gründe sorgen für ein funktionsfähiges Regelventil, welches kostenreduziert herstellbar ist. Furthermore, the invention provides that the carrier element has axial steps, so that the sealing element and the Federabstützelement can engage at least positively in the carrier element. These steps are easy to produce, especially in plastic materials. Also conceivable would be a modular system with pre-assembled units. Thus, the carrier element made of PVDF could be connected to the sealing element made of PTFE, positive, non-positive or cohesive. Likewise, a preassembled unit with a spring support made of metal or preferably made of PTFE and a with a positive, non-positive or cohesively associated sealing ring would be conceivable. For example, it would be possible to inject the seals onto the respective support elements (spring support element, carrier element). Then the two components would have to be fitted only in the feed port of the valve housing and biased by the compression spring against the valve member. Through this procedure, the assembly times can be shortened and installation errors can be avoided by reducing the items. The above reasons provide a functioning control valve, which can be produced at reduced cost.
Optional kann das Regelventil in einem Wärmemanagementmodul zum Einsatz kommen, da dort die Ventile bzw. die Ventildichtungen hohen Temperaturschwankungen ausgesetzt sind.Optionally, the control valve can be used in a thermal management module, since there the valves or the valve seals are exposed to high temperature fluctuations.
