Abstract

Die Erfindung betrifft eine Ventil- oder Drosselvorrichtung (1) für eine fluide Strömung, insbesondere eine feststofführende Strömung, insbesondere eine Stoffsuspension oder Siebwasser einer Papiermaschine mit einem flüssigkeitsdurchströmten Hohlkörper (2) mit einer Eintritts- (3) und einer Ausgangsöffnung (8) und einem Mittel zur Veränderung eines Strömungsquerschnittes (4) im Hohlkörper.The invention relates to a valve or throttle device (1) for a fluid Flow, in particular a flow carrying solids, in particular a flow Stock suspension or white water of a paper machine with a liquid-flowing hollow body (2) with an inlet (3) and one Exit opening (8) and a means for changing a Flow cross section (4) in the hollow body.

Die Erfindung ist dadurch gekennzeichnet, daß der, den Hohlraum (2.1) bildende Hohlkörper (2) derart geteilt ist, daß nach seinem Öffnen alle vor dem Öffnen innenliegenden Oberflächen zur Reinigung zugänglich sind, ohne daß das Ventil von seiner Zu- und/oder Abfuhrleitung getrennt werden muß.

Figure 00000001
The invention is characterized in that the hollow body (2) forming the cavity (2.1) is divided in such a way that, after opening, all the surfaces inside before opening are accessible for cleaning without the valve being removed from its supply and / or discharge line must be separated.
