Abstract

Metering devices with diaphragm pistons are especially suitable for aggressive media, since in their case no friction occurs between piston and cylinder. The diaphragm 1 is pressurised on the spatial side 2 with pressure fluid from the control device 3 and, on the other side, displaces the highly viscous liquid in the working space 4. The liquid delivered is controlled by the two ball valves 5 and 6 and corresponds with high accuracy to the pressure fluid fed through the control device 3. <IMAGE>

Description

Dosiergeräte mit Membrankolben sind besonders geeignet für aggressive Flüssigkeiten, weil hier keine Reibung zwischen Kolben und Zylinder stattfindet.Dosing devices with membrane pistons are special suitable for aggressive liquids because no friction between piston and cylinder here takes place.

Die Fig. 1 zeigt eine Ausführung eines Dosier­ gerätes mit Membrane. Die Membrane 1 wird auf der Raumseite 2 mit Druckflüssigkeit von dem Steuergerät 3 über die Leitung 7 beaufschlagt und verdrängt auf der anderen Seite die hoch­ viskose Flüssigkeit im Arbeitsraum 4. Die geförderte Flüssigkeit wird durch die beiden Kugelhähne 5 und 6 gesteuert und entspricht mit großer Genauigkeit der zugeführten Flüssigkeitsmenge durch das Steuergerät 3. Fig. 1 shows an embodiment of a dosing device with a membrane. The membrane 1 is pressurized with pressure fluid from the control unit 3 via the line 7 on the room side 2 and displaces the highly viscous liquid in the working space 4 on the other side. The liquid delivered is controlled by the two ball valves 5 and 6 and corresponds with great accuracy to the amount of liquid supplied by the control unit 3 .

Das Steuergerät 3 wird von einem hier nicht dargestellten Hydraulikaggregat betrieben. Es enthält den Druckkolben 8, der über die Kolbenstange 9 auf den Dosierkolben 10 einwirkt. Der Arbeitsraum 11 ist über die Leitung 7, die Bohrungen 12 und 13 mit der Raumseite 2 verbunden. Der Hub des Dosierkolbens 10 wird über die Kolbenstange 9 durch die Schraube 14 eingestellt und damit wird die Fördermenge festgelegt.The control unit 3 is operated by a hydraulic unit, not shown here. It contains the pressure piston 8 , which acts on the metering piston 10 via the piston rod 9 . The work space 11 is connected to the room side 2 via the line 7 , the bores 12 and 13 . The stroke of the metering piston 10 is set via the piston rod 9 by the screw 14 and the delivery rate is thus determined.

Zur besseren Wartung und Reinigung ist das Oberteil 15 mit der Membrane 1 nach Lösen der Schraube 16 um den Gelenkpunkt 17 schwenkbar und gibt den Arbeitsraum 4 frei.For better maintenance and cleaning, the upper part 15 with the membrane 1 can be pivoted about the hinge point 17 after loosening the screw 16 and frees the working space 4 .

Die Membrane 1 kann je nach Bedarf aus mehreren Einzelmembranen bestehen.The membrane 1 can consist of several individual membranes as required.
