Description
Die Erfindung betrifft ein Umschaltventil in einem Verbundflüssigkeitszähler, das einen Klappenkörper und eine an einem die Fortsetzung eines Durchflußkanals im Gehäuse bildenden ringförmigen Vorsprung angebrachte Lippendichtung besitzt, wobei sich die Lippe der Lippendichtung in der Schließstellung reibungsfrei und ungeführt auf die Gegenfläche am Klappenkörper auflegt. The invention relates to a changeover valve in a compound liquid meter, one valve body and one on one the continuation of a flow channel has a lip seal attached to the housing forming an annular projection, wherein the lip of the lip seal in the closed position is frictionless and placed unguided on the mating surface on the valve body.
Bei Verbundwasserzählern ist es bekannt, das Umschaltventil bzw. den Klappenkörper mit einer Lippendichtung zu versehen. Der dem Ventilsitz zugekehrte Teil von ihr (die eigentliche Lippe) ist derartig schmiegsam ausgebildet, daß diese Lippe mit ihrer freien Kante bis zum vollständigen Abheben dichtend mit dem Ventilsitz Verbindung hat und sich beim Schließvorgang reibungsfrei und ungeführt auf den Ventilsitz auflegt. Es handelt sich also hier um eine Wegabdichtung, die bei Verbundwasserzählern vorhanden sein muß, um Zwischenstellungen des Klappenkörpers bei Beginn der Öffnungsbewegung zu vermeiden. Es könnten dadurch sonst große Meßfehler entstehen. In the case of compound water meters, it is known to use the switching valve or to provide the valve body with a lip seal. The one facing the valve seat Part of it (the actual lip) is so pliable that this The lip with its free edge seals with the valve seat until it is completely lifted off Connection has and is friction-free and unguided on the valve seat during the closing process hangs up. This is a way of sealing off the path, which is the case with composite water meters must be available to intermediate positions of the valve body at the beginning of the opening movement to avoid. Otherwise large measurement errors could result.
Bei stark verschmutzten Flüssigkeiten, beispielsweise sandhaltigem Wasser, ergeben sich Schwierigkeiten bei derartigen Lippendichtungen insofern, als sich hinter der frei beweglichen Lippe, vorzugsweise am untenliegenden Teil des Dichtringes, Ablagerungen bilden können, welche die Funktion der Lippendichtung nach kürzerer oder längerer Zeit, entsprechend dem Grad der Verschmutzung, beeinträchtigen. In the case of heavily soiled liquids, such as those containing sand Water, there are difficulties with such lip seals insofar as behind the freely movable lip, preferably on the lower part of the Sealing ring, deposits can form, which the function of the lip seal after a shorter or longer period of time, depending on the degree of soiling.
Es ist bei dem Umschaltventil eines Verbundflüssigkeitszählers bekannt, die Dichtungslippe am Ventilsitz anzuordnen (deutsche Patentschrift 323 612). Die Dichtungslippe hat V-förmigen Querschnitt, und ihre Schenkel liegen fast über ihre ganze Länge an dem Vorsprung an. Der Innenraum der Dichtung ist völlig offen und gibt dem Schmutz allseitig freien Zutritt, wodurch Störungen in der Lippenfunktion auftreten können. It is known in the switching valve of a compound liquid meter, to arrange the sealing lip on the valve seat (German Patent 323 612). the Sealing lip has a V-shaped cross-section, and its legs are almost above hers the entire length of the protrusion. The interior of the seal is completely open and Gives the dirt free access on all sides, which causes disorders in the lip function may occur.
Aufgabe der Erfindung ist es, eine Lippendichtung zu schaffen, bei welcher derartige Ablagerungen nicht oder nur im unerheblichen Maße auftreten können. The object of the invention is to create a lip seal at which such deposits cannot occur or can only occur to an insignificant extent.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Innenraum der Lippendichtung in der Offenstellung des Klappenkörpers durch den ringförmigen Vorsprung an dem Durchflußkanal des Gehäuses abgedeckt ist. According to the invention this object is achieved in that the interior the lip seal in the open position of the valve body through the annular Is covered projection on the flow channel of the housing.
Es darf dazu bemerkt werden, daß Ablagerungen hinter der Lippe im wesentlichen nur auftreten, wenn der Klappenkörper geöffnet ist und ein Durchfluß stattfindet. Im ruhenden Zustand, wenn die Klappe geschlossen ist, kann in den Raum innerhalb der Lippendichtung kein Schmutz gelangen und sich infolgedessen auch nicht ablagern. It should be noted that deposits behind the lip in the essentially only occur when the valve body is open and there is flow takes place. In the resting state, when the flap is closed, you can enter the room no dirt can get inside the lip seal and, as a result, neither does it deposit.
Ein weiterer Vorteil der erfindungsgemäßen Maßnahme besteht darin, daß die Lippe durch das strömende Wasser nicht zerstört oder beschädigt werden kann, also keine Erosionserscheinungen auftreten, weil die Dichtung nicht mehr der Strömung ausgesetzt ist. Another advantage of the measure according to the invention is that that the lip cannot be destroyed or damaged by the flowing water, so no erosion phenomena occur because the seal is no longer the flow is exposed.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig. 1 einen senkrechten Schnitt durch das Umschaltventil im geöffneten Zustand und F i g. 2 desgleichen in der Schließstellung. An exemplary embodiment of the invention is shown in the drawing. It shows Fig. 1 a vertical section through the changeover valve in the open State and F i g. 2 also in the closed position.
Ein einen Durchflußkanal 1 umgebender rohrförmiger Stutzen 2 ist an seinem abflußseitigen Ende mit einem ringförmigen Vorsprung 3 versehen. Durch diesen Vorsprung 3 wird eine an einem Gehäuse 4 befestigte Lippendichtung 5 mit ihrer Lippe 6 so weit abgedeckt, daß der Raum hinter der Lippe 6 nicht mit Schmutz od. dgl. vollgespült werden kann. A tubular connecting piece 2 surrounding a flow channel 1 is provided with an annular projection 3 at its end on the outflow side. By this projection 3 is attached to a housing 4 lip seal 5 with their lip 6 covered so far that the space behind the lip 6 is not covered with dirt or the like. Can be fully flushed.
In der Schließstellung legt sich ein Klappenkörper 7 mit einem ringförmigen Vorsprung 8 auf die Lippe 6 auf und drückt diese so weit nach innen, bis sich der Rand 9 des Klappenkörpers 7 auf einen dicken, ringförmigen Wandungsteil 10 der Lippendichtung 5 legt. Die Lippe 6 wird dabei nach innen gebogen, wie aus der F i g. 2 ersichtlich. In the closed position, a flap body 7 lies with an annular one Projection 8 on the lip 6 and pushes it inward until the Edge 9 of the valve body 7 on a thick, annular wall part 10 of the lip seal 5 sets. The lip 6 is bent inward, as shown in FIG. 2 can be seen.
