Description
Umschaltventil für Verbundwassermesser. Die Erfindung besteht in einer besonderen Konstruktion der an sich bekannten Umschaltventile für Verbundwassermesser, bei denen durch die Bewegung eines Rollkörpers eine Druckentlastung eintritt. Sie ist in den Ansprüchen gekennzeichnet und wird im folgenden näher beschrieben. Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt.Switching valve for compound water meter. The invention consists in one special construction of the known switching valves for compound water meters, in which a pressure relief occurs through the movement of a roller. she is characterized in the claims and is described in more detail below. A Exemplary embodiment of the subject matter of the invention is shown in the drawing.
Abb. i ist ein Längsschnitt durch das Umschaltventil, und zwar in der Stellung, in welcher nur der Nebenmesser in Tätigkeit ist.Fig. I is a longitudinal section through the switching valve, namely in the position in which only the secondary knife is in action.
Abb. 2 zeigt die Stellung, in welcher beide Messer registrieren.Fig. 2 shows the position in which both knives register.
In dem Ventilgehäuse a sitzt der als Ventilsitz ausgebildete Einsatz b. Der Ventilkegel c hat einerseits Führung im Einsatz b, anderseits in dem mit " einer Führungsbüchse d ausgestatteten - Oberteil e. Dieses dient zur Aufnahme des Rollkörpers f, gleichzeitig aber auch als Verschlußdeckel für das Ventilgehäuse a, und hat im Innern eine geneigte Kante h. Zwecks sicherer Lagerung des Rollkörpers f ist der Kolben des Ventilkegels c mit einer entsprechenden Vertiefung versehen.The insert b designed as a valve seat sits in the valve housing a. The valve cone c has a guide in the insert b on the one hand and in the upper part e equipped with a guide bushing d on the other hand. This serves to accommodate the roller body f, but at the same time also serves as a cover for the valve housing a, and has an inclined edge h inside. For the purpose of secure storage of the roller body f, the piston of the valve cone c is provided with a corresponding recess.
Bei der in Abb. i veranschaulichten Stellung des Umschaltventils ist, wie oben gesagt, nur der Nebenmesser in Tätigkeit. Das Wasser wird durch den als Hohlzylinder ausgeführten Ventilkegel c durch die Kanäle g dem Nebenmesser zugeführt.In the position of the switching valve illustrated in Fig. I, as said above, only the secondary knife in action. The water is passed through the as Hollow cylinder executed valve cone c supplied through the channels g to the secondary knife.
Wird nun durch die an sich bekannten Vorgänge infolge Anhebens des Ventilkegels c auch dem großen Messer Wasser zugeführt, so rollt der Körper f an der geneigten Kante h des Oberteils e ab, und zwar so lange, bis er :von dem Kolben des Ventilkegels c abfällt (s.. Abb. 2). Der Ventilkegel c wird dadurch naturgemäß entlastet. Diese Entlastung bewirkt, daß das Ventil sich sofort auf den entsprechenden freien Durchgangsquerschnitt einstellt,. so daß der Druckverlust bedeutend ermäßigt wird.If water is now supplied to the large knife as a result of the known processes as a result of lifting the valve cone c, the body f rolls off the inclined edge h of the upper part e until it: falls from the piston of the valve cone c (see Fig. 2). The valve cone c is naturally relieved. This relief has the effect that the valve adjusts itself immediately to the corresponding free passage cross-section. so that the pressure loss is significantly reduced.
Wird nun durch die ebenfalls an sich bekannten Vorgänge das Ventil wieder geschlossen, so rollt der Körper f in seine Ausgangsstellung zurück. Das Ventil wird also aufs neue wieder belastet.The valve is now due to the processes that are also known per se closed again, the body f rolls back into its starting position. That So the valve is loaded again.
