Description
Die Erfindung betrifft ein Ablaufventil für einen sanitären Spülkasten, insbesondere Toiletten-Spülkasten, mit einer Ventilfassung, einem eine Dichtfläche oder Dichtung aufweisenden Ventilkörper, der in der Ventilfassung beweglich geführt ist, und einem eine Ablauföffnung begrenzenden Ventilsitz, wobei die Dichtfläche oder Dichtung im geschlossenen Zustand des Ablaufventils auf dem Ventilsitz aufliegt und im geöffneten Zustand des Ablaufventils die Ablauföffnung freigibt, und wobei die Ventilfassung über mindestens einen vertikalen Abstandshalter, der mindestens eine dem Ventilsitz in Spülstromfließrichtung vorgeordnete Einströmfläche definiert, mit dem Ventilsitz verbunden ist.The invention relates to a drain valve for a sanitary cistern, in particular toilet cistern, with a valve seat, a valve body having a sealing surface or seal, which is movably guided in the valve seat, and a drain opening limiting valve seat, wherein the sealing surface or seal in the closed state the drain valve rests on the valve seat and releases the drain opening in the opened state of the drain valve, and wherein the valve seat is connected to the valve seat via at least one vertical spacer defining at least one inflow surface upstream of the valve seat in the purge flow direction.
Derartige Ablaufventile sind bekannt (siehe z.B.
Die Stärke des Spülstroms in einer Toilette oder einem Urinal ist von der Höhendifferenz zwischen Spülkasten und Sanitärkeramik, dem Strömungswiderstand des den Spülkasten mit der Sanitärkeramik verbindenden Spülrohres und dem Strömungswiderstand der Sanitärkeramik abhängig. Ist der Spülstrom zu stark, kann dies zu Wasserspritzern aus der Sanitärkeramik heraus auf die Toilettenbrille und auf den Boden neben die Sanitärkeramik führen. Um durch einen zu starken Spülstrom verursachte Wasserspritzer zu vermeiden, wird der Spülstrom gegebenenfalls gedrosselt. Hierzu werden herkömmlicherweise verschiedene Drosselringe mit unterschiedlichen Durchmessern in den Ventilsitz des Ablaufventils eingelegt, um den Strömungsquerschnitt im Ventilsitz zu verringern. Die Einstellung des Spülstroms mit den verschiedenen Drosselringen ist aufwendig und unkomfortabel. Zudem können einzelne der Drosselringe verlorengehen, was dann eine zufriedenstellende Einstellung des Spülstroms ausschließen kann.The strength of the purge flow in a toilet or urinal is dependent on the height difference between the cistern and sanitary ware, the flow resistance of the cistern connected to the sanitary ware cistern and the flow resistance of the sanitary ware. If the flushing flow is too strong, this can lead to water splashes from the sanitary ware on the toilet seat and on the floor next to the sanitary ware. In order to avoid water splashes caused by excessive flushing flow, the flushing flow may be throttled. For this purpose, conventionally different throttle rings are inserted with different diameters in the valve seat of the drain valve to reduce the flow area in the valve seat. The adjustment of the purge flow with the various throttle rings is complicated and uncomfortable. In addition, individual of the throttle rings can be lost, which can then rule out a satisfactory adjustment of the purge flow.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung bereitzustellen, mittels der sich der Spülstrom aus einem sanitären Spülkasten komfortabler und zuverlässig einstellen lässt.The invention has for its object to provide a device by means of which the purge flow from a sanitary cistern can be set more comfortable and reliable.
Gelöst wird diese Aufgabe durch ein Ablaufventil mit den in Anspruch 1 angegebenen Merkmalen. Bevorzugte und vorteilhafte Ausgestaltungen des erfindungsgemäßen Ablaufventils sind in den Unteransprüchen angegeben.This object is achieved by a drain valve having the features specified in claim 1. Preferred and advantageous embodiments of the drain valve according to the invention are specified in the subclaims.
Das erfindungsgemäße Ablaufventil ist dadurch gekennzeichnet, dass an dem mindestens einen Abstandshalter und/oder der Ventilfassung mindestens ein Spülstrom-Drosselelement verstellbar gelagert ist, wobei durch Drehen und/oder Verschieben des mindestens einen Spülstrom-Drosselelements relativ zu dem Abstandshalter die wirksame Größe der in Spülstromfließrichtung dem Ventilsitz vorgeordneten Einströmfläche veränderbar ist.The drainage valve according to the invention is characterized in that on the at least one spacer and / or the valve seat at least one purge flow throttle element is adjustably mounted, wherein by rotating and / or moving the at least one purge flow throttle element relative to the spacer, the effective size of Spülstromfließrichtung the inlet valve upstream of the valve seat is variable.
Die Erfindung schafft die Möglichkeit, eine Einstellung des Spülstroms mittels vorzugsweise nur eines einzelnen verstellbaren Elements durchführen zu können. Da somit nicht mehr verschiedene Drosselringe mit unterschiedlichen Innendurchmessern in den Ventilsitz eingelegt werden müssen, gestaltet sich die Einstellung des Spülstroms mit dem erfindungsgemäßen Ablaufventil erheblich komfortabler als mit den herkömmlichen Drosselringen. Zudem bietet die Erfindung einen Kostenvorteil, da sie nur ein Zusatzteil (Spülstrom-Drosselelement) für unterschiedliche Einstellungen des Spülstroms erfordert.The invention makes it possible to carry out an adjustment of the flushing flow by means of preferably only a single adjustable element. Since therefore no longer different throttle rings with different inner diameters must be inserted into the valve seat, the setting of the purge flow with the drain valve according to the invention designed considerably more comfortable than with the conventional throttle rings. In addition, the invention offers a cost advantage, since it requires only one additional part (flushing flow throttle element) for different settings of the purge flow.
Die Erfindung basiert auf dem Grundgedanken, dass eine Strömungsquerschnittsreduzierung zur Verringerung der Spülstromstärke nicht im Ablauf des Ventilsitzes erfolgen muss, sondern auch an anderer Stelle im Bereich des Ventilsitzes angeordnet werden kann.The invention is based on the idea that a flow cross-section reduction to reduce the purge current does not have to take place in the outlet of the valve seat, but can also be arranged elsewhere in the region of the valve seat.
Vorzugsweise ist das mindestens eine Spülstrom-Drosselelement des erfindungsgemäßen Ablaufventils hülsenförmig oder hohlzylindrisch ausgebildet. Hierdurch lässt sich das mindestens eine Drosselelement sehr gut mit der Gehäuseform bzw. Ventilfassungsform bewährter Ablaufventile kombinieren.Preferably, the at least one purge flow throttle element of the drain valve according to the invention is sleeve-shaped or hollow cylindrical. As a result, the at least one throttle element can be combined very well with the housing shape or valve guide form of proven drainage valves.
Die Verstellbarkeit des erfindungsgemäßen Spülstrom-Drosselelements lässt in verschiedenen Ausführungen verwirklichen. Eine Ausführungsform besteht zum Beispiel darin, dass die wirksame Größe der Einströmfläche mittels des mindestens einen Spülstrom-Drosselelements in Stufen, insbesondere Raststufen veränderbar ist. In dieser Ausgestaltung lässt sich die wirksame Größe der Einströmfläche sehr komfortabel in Abhängigkeit von einem bestimmten Sanitärkeramikmodell und/oder einer bestimmten Höhendifferenz zwischen Spülkasten und Sanitärkeramik einstellen. Dabei kann dem Installateur beispielsweise eine Tabelle zur Verfügung gestellt werden, in der verschiedene Sanitärkeramikmodelle und/oder verschiedene Werte bezüglich der Höhendifferenz zwischen Spülkasten und Sanitärkeramik angegeben sind, wobei den verschiedenen Sanitärkeramikmodellen und/oder Höhendifferenzen spezifische Einstell- oder Raststufen des Spülstrom-Drosselelements zugeordnet sind. Der Installateur kann der Tabelle dann die für das jeweilige Sanitärkeramikmodell bzw. die jeweilige Höhendifferenz geeignete Einstell- oder Raststufe entnehmen und dementsprechend mittels des mindestens einen Spülstrom-Drosselelements die wirksame Größe der Einströmfläche passend einstellen.The adjustability of the purge flow throttle element according to the invention can be realized in various embodiments. An embodiment consists, for example, in that the effective size of the inflow surface can be changed by means of the at least one flushing flow throttle element in steps, in particular latching steps. In this embodiment, the effective size of the inflow can be very comfortably set depending on a particular sanitary ware model and / or a certain height difference between the cistern and sanitary ware. In this case, for example, a table can be made available to the installer, in which various sanitary ceramic models and / or different values with respect to the height difference between the cistern and sanitary ware are specified, the specific sanitary ware models and / or height differences being assigned specific setting or detent stages of the flushing flow throttle element , The installer can then take the table for the respective sanitary ware model or the respective height difference suitable adjustment or detent stage and accordingly adjust the effective size of the inflow by means of at least one purge flow throttle element.
In diesem Zusammenhang sieht eine vorteilhafte Ausgestaltung der Erfindung vor, dass der Abstandshalter und/oder die Ventilfassung mindestens ein erstes Rastelement aufweist, wobei das mindestens eine Spülstrom-Drosselelement mindestens ein mit dem mindestens einen ersten Rastelement zusammenwirkendes zweites Rastelement aufweist. Hierdurch wird eine besonders zuverlässige und zugleich komfortable Einstellbarkeit der wirksamen Größe der Einströmfläche in vorgegebenen Stufen erzielt.In this context, an advantageous embodiment of the invention provides that the spacer and / or the valve socket has at least one first latching element, wherein the at least one flushing flow throttle element has at least one second latching element cooperating with the at least one first latching element. As a result, a particularly reliable and at the same time comfortable adjustability of the effective size of the inflow surface is achieved in predetermined stages.
Eine alternative Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass durch Drehen oder Verschieben des mindestens einen Spülstrom-Drosselelements die wirksame Größe der Einströmfläche stufenlos veränderbar ist. Diese Ausgestaltung bietet den Vorteil, dass die Stärke des Spülstroms sehr fein verändert und dadurch optimal eingestellt werden kann. Hierzu weisen der mindestens eine Abstandshalter und/oder die Ventilfassung vorzugsweise ein Gewinde, beispielsweise ein Außengewinde auf, wobei dann das mindestens eine Spülstrom-Drosselelement ein mit dem Gewinde kämmendes Gegen- oder Innengewinde aufweist.An alternative embodiment of the invention is characterized in that by rotation or displacement of the at least one purge flow throttle element, the effective size of the inflow is continuously variable. This embodiment offers the advantage that the strength of the purge flow can be changed very finely and thus optimally adjusted. For this purpose, the at least one spacer and / or the valve socket preferably have a thread, for example an external thread, in which case the at least one flushing flow throttle element has a counter-threading or internal thread meshing with the thread.
Nach einer weiteren Ausgestaltung des erfindungsgemäßen Ablaufventils weist das mindestens eine Spülstrom-Drosselelement an seiner Außenseite mindestens einen nach außen vorstehenden Vorsprung auf. Der Vorsprung kann als Grifffläche genutzt werden und erleichtert die Handhabung des Spülstrom-Drosselelements.According to a further embodiment of the drain valve according to the invention, the at least one purge flow throttle element on its outer side at least one outwardly projecting projection. The projection can be used as a gripping surface and facilitates the handling of the Spülstrom-throttle element.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass das mindestens eine Spülstrom-Drosselelement an seiner Außenseite mindestens ein Symbol aufweist, welches eine Bewegung und/oder Bewegungsrichtung des Spülstrom-Drosselelements für eine Verkleinerung oder Vergrößerung der Einströmfläche angibt. Durch ein solches Symbol wird die Bedienungsfreundlichkeit des mindestens einen Spülstrom-Drosselelements weiter gesteigert.A further advantageous embodiment of the invention provides that the at least one purge flow throttle element has on its outer side at least one symbol which indicates a movement and / or direction of movement of the purge flow throttle element for a reduction or enlargement of the inflow surface. Such a symbol further enhances the ease of operation of the at least one purge flow throttle element.
In konstruktiver sowie funktionaler Hinsicht ist es günstig, wenn gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung die Ventilfassung oberhalb des mindestens einen Abstandshalters einen hülsenförmigen oder hohlzylindrischen Abschnitt aufweist, der von dem mindestens einen Spülstrom-Drosselelement umgeben ist und eine dem Ventilsitz zugewandte Unterkante aufweist, wobei das Spülstrom-Drosselelement in einer Stellung, in welcher die wirksame Größe der Einströmfläche maximal ist, nicht gegenüber der Unterkante vorsteht.In constructive and functional terms, it is advantageous if according to a further preferred embodiment of the invention, the valve socket above the at least one spacer has a sleeve-shaped or hollow cylindrical portion which is surrounded by the at least one purge flow throttle element and a valve seat facing lower edge, wherein the purge flow throttle element in a position in which the effective size of the inflow is maximum, does not protrude from the lower edge.
Eine weitere Ausgestaltung des erfindungsgemäßen Ablaufventil sieht vor, dass die verstellbare Lagerung des mindestens einen Spülstrom-Drosselelements derart ausgebildet ist, dass das Spülstrom-Drosselelement in seiner tiefsten Stellung relativ zu dem mindestens einen Abstandshalter noch einen vorgegebenen Spülstrom zulässt bzw. sicherstellt.A further embodiment of the drain valve according to the invention provides that the adjustable mounting of the at least one purge flow throttle element is designed such that the purge flow throttle element still allows or ensures a predetermined purge flow in its lowest position relative to the at least one spacer.

Der Ventilsitz 3 ist über Abstandshalter 6, 7 mit der Ventilfassung des Ablaufventils 4 verbunden. Die Abstandshalter 6, 7 sind stegförmig ausgebildet und an dem Rohrstutzen 3.1 des Ventilsitzes 3 angebracht, vorzugsweise angeformt. Sie weisen einen von dem Rohrstutzen 3.1 radial nach außen vorspringenden Stegabschnitt 6.1, 7.1 und einen sich daran anschließenden, im Wesentlichen vertikal verlaufenden Stegabschnitt 6.2, 7.2 auf. Der untere Teil 8 der Ventilfassung oberhalb der Abstandshalter 6, 7 ist im Wesentlichen hülsenförmig oder hohlzylindrisch ausgebildet. Mit W ist in
Dem Ventilsitz 3 ist ein Ventilkörper 9 zugeordnet, der als Überlaufrohr ausgebildet und in der Ventilfassung axialbeweglich geführt ist. An seinem unteren Ende weist der Ventilkörper 9 eine ringförmige Dichtfläche oder Dichtung 10 auf. Im geschlossenen Zustand des Ablaufventils 4 liegt die Dichtfläche oder Dichtung 10 auf dem Ventilsitz 3 auf (siehe insbesondere
Der Ventilsitz 3 ist in den in der Zeichnung dargestellten Ausführungsbeispielen mit vier Abstandshaltern 6, 7 versehen, die im Wesentlichen gleichmäßig über den Umfang des Ventilsitzes 3 verteilt angeordnet sind. Anstelle von vier Abstandshaltern 6, 7 kann der Ventilsitz 3 auch nur drei, zwei oder nur einen Abstandshalter aufweisen, wobei im Falle eines einzigen Abstandshalters dieser breiter als der jeweilige Abstandshalter 6, 7 der mehreren stegförmigen Abstandshalter 6, 7 ausgebildet ist. Der oder die mehreren Abstandshalter 6, 7 definieren mindestens eine dem Ventilsitz 3 in Spülstromfließrichtung vorgeordnete Einströmfläche E. Die Einströmfläche E kann auch als Einströmquerschnitt bezeichnet werden. In den in der Zeichnung dargestellten Ausführungsbeispielen ist die den Ventilsitz 3 umgebende Einströmfläche E im Wesentlichen ringförmig oder zylindrisch ausgeführt, wobei die Abstandhalter 6, 7 die Einströmfläche E in bogenförmige Abschnitte (Öffnungsabschnitte) untergliedern.The
An den Abstandshaltern 6, 7 und dem unteren Teil 8 des Ventilgehäuses ist ein Spülstrom-Drosselelement 11 verstellbar gelagert. Durch Drehen und Verschieben des Spülstrom-Drosselelements 11 relativ zu den Abstandshaltern 6, 7 bzw. der Ventilfassung 8 (sowie dem Ventilsitz 3) lässt sich die wirksame Größe der Einströmfläche E verändern und damit der bei geöffnetem Ventil aus dem Ventilsitz 3 durch den Rohrstutzen 3.1 fließende Spülstrom einstellen. Das Spülstrom-Drosselelement 11 ist ringförmig, vorzugsweise im Wesentlichen hülsenförmig oder hohlzylindrisch ausgebildet.At the
Die Abstandshalter 6, 7 und der untere Teil 8 der Ventilfassung einerseits und das Spülstrom-Drosselelement 11 andererseits weisen einander zugeordnete Rastelemente auf. Die Rastelemente sind in Form einer im Wesentlichen vertikal verlaufenden Reihe von Ausnehmungen 12 und mindestens einer den Ausnehmungen zugeordneten Rastnase 11.1 ausgeführt. Die in einer Reihe angeordneten Ausnehmungen 12 sind an dem vertikal verlaufenden Stegabschnitt 6.2 mindestens eines der Abstandshalter 6 außenseitig bzw. im Kantenbereich des Stegabschnitts 6.2 ausgebildet, während die Rastnase 11.1 am Innenumfang des Spülstrom-Drosselelements 11 vorgesehen ist.The
Des Weiteren sind an dem vertikal verlaufenden Stegabschnitt 7.2 mindestens eines anderen der Abstandshalter 7 außenseitig im Wesentlichen horizontal und parallel zueinander verlaufenden Rippen bzw. Nuten 13 ausgebildet, denen mindestens ein am Innenumfang des Spülstrom-Drosselelements 11 ausgebildetes Zahnelement 11.2 zugeordnet ist. Das Zahnelement 11.2 ist an einem federelastischen Abschnitt 11.3 des Spülstrom-Drosselelements 11 ausgebildet. Der Abschnitt 11.3 ist durch einen U-förmigen Spalt 11.4 in dem Spülstrom-Drosselelements 11 definiert und kann auch als Federlasche oder Federsteg bezeichnet werden. Das Zahnelement 11.2 verhindert ein unbeabsichtigtes Entriegeln des Spülstrom-Drosselelements 11, da es beim Drehen des Spülstrom-Drosselelements 11 durch nach außen gerichtete Auslenkung einen der stegförmigen Abstandshalter 6, 7 überwinden muss.Furthermore, on the vertically extending web section 7.2 of at least one other of the
