Abstract
Description
Die Erfindung betrifft ein Rückschlagventil nach dem Oberbegriff von Anspruch 1.The invention relates to a check valve according to the preamble of
Ein derartiges Rückschlagventil ist beispielsweise aus der
Aus diesem Grund ist es bekannt, gehäusefeste Begrenzungsmittel gegenüberliegend von dem Ventilsitz vorzusehen, an denen der Dichtkörper bei einem in Durchlassrichtung vorliegenden Mindestdruck zur Anlage kommt, so dass in der Durchlassstellung unabhängig vom anliegenden Überdruck ein definierter Druckverlust vorliegt. Beispielsweise offenbart
Bei den beiden zuvor beschriebenen Bauformen ist zur Erzielung eines geeigneten definierten Druckverlustes eine erhebliche Verformung erforderlich, was einen erhöhten Verschleiß des Dichtkörpers verursachen kann. Des Weiteren ist es fertigungstechnisch unumgänglich, die Begrenzungsmittel für den Dichtkörper und den Ventilsitz an separaten, miteinander zu verbindenden Gehäuseteilen anzuordnen. Die mindestens zwei Gehäuseteile und der zusätzlich erforderliche Montageschritt des Verbindens der Gehäuseteile führen zu einem insgesamt erhöhten Aufwand.In the two designs described above, a significant deformation is required to achieve a suitable defined pressure loss, which can cause increased wear of the sealing body. Furthermore, it is unavoidable in terms of manufacturing technology to arrange the limiting means for the sealing body and the valve seat on separate housing parts to be connected to one another. The at least two housing parts and the additionally required mounting step of connecting the housing parts lead to an overall increased effort.
Bei einer anderen Bauform ist der Ventilkörper als eine schwenkbar gelagerte Klappe ausgeführt, siehe beispielsweise
Die Aufgabe der Erfindung besteht darin, ein einfaches und robustes Rückschlagventil bereitzustellen, das vorteilhaft mit geringem Aufwand herstellbar und montierbar ist und bei dem der Druckverlust optimal einstellbar ist.The object of the invention is to provide a simple and robust check valve, which can be advantageously produced and assembled with little effort and in which the pressure loss is optimally adjustable.
Die Erfindung löst diese Aufgabe mit den Merkmalen des Anspruchs 1. Durch die axiale Führung des Ventilköpers wird dieser bei Anliegen eines Überdrucks in Durchlassrichtung einfach in die Durchlassstellung verschoben und gibt ohne übermäßige eigene Verformung eine definierte Durchlassöffnung mit einem optimal einstellbaren Druckverlust frei.The invention achieves this object with the features of
Den gesamten Dichtkörper überdeckende, an einem separaten Gehäuseteil anzuordnende Begrenzungsmittel für den Dichtkörper sind nicht erforderlich, so dass das Gehäuse vorteilhaft einstückig gefertigt und ein Verbinden von Gehäuseteilen in der Montage demnach überflüssig sein kann.The entire sealing body overlapping, to be arranged on a separate housing part limiting means for the sealing body are not required, so that the housing advantageously made in one piece and a connection of housing parts in the assembly can therefore be redundant.
An dem Haltemittel ist vorteilhafterweise ein Anschlagmittel für eine Begrenzung der Verschiebung des Dichtkörpers vorgesehen. Dieses Anschlagmittel kann beispielsweise einfach durch Umformen des freien Endes eines stiftförmigen Haltemittels erzeugt werden.At the holding means a stop means for limiting the displacement of the sealing body is advantageously provided. This stop means can be produced, for example, simply by forming the free end of a pin-shaped holding means.
Die Erfindung wird im Folgenden anhand vorteilhafter Ausführungsformen unter Bezugnahme auf die beigefügten Figuren erläutert. Dabei zeigtThe invention will be explained below with reference to advantageous embodiments with reference to the accompanying figures. It shows
