Abstract
Description
Die Neuerung betrifft ein Druckreduzierventil für abrasive Suspensionen, bestehend aus einer Ventilkammer, einer Drossel einer Düsennadel und Düsennadellagerung.The innovation concerns a pressure reducing valve for abrasive Suspensions consisting of a valve chamber and a throttle a nozzle needle and nozzle needle bearing.
Druckreduzierventile der eingangs genannten Art sind im Maschinenbau in vielfältiger Ausführung auch als "einstellbare Düse" bekannt. Oftmals wird mit ihnen Dampf auf eine vorgegebene Größe heruntergedrosselt, wobei die Steuerung des Dampfdruckes über eine Membran und eine Spindel auf das kegelförmige Drossel ventil erfolgt. Auch wenn es bei diesen Einrichtungen um die Regelung relativ sauberen Prozeßdampfes geht, werden zum Auf fangen von Rostteilchen und anderen Partikeln Filter in die Dampfleitung eingebaut.Pressure reducing valves of the type mentioned are in Mechanical engineering in various designs also as "adjustable Nozzle "is known. Often, they are used to steam to a predetermined Size throttled down, controlling vapor pressure via a membrane and a spindle on the conical throttle valve is done. Even if these institutions are concerned with Control of relatively clean process steam is going on trap rust particles and other particles in the filter Steam line installed.
Besondere Probleme ergeben sich, wenn anstelle von Dampf abrasive Suspensionen, wie beispielsweise Bauxitsuspensionen durch das Druckreduzierventil geschickt werden. Nach kurzer Zeit ist die Druckreduzierung durch die hohe Verschleißrate nicht ausreichend und kann den vorgegebenen Sollwert nicht mehr ein halten.Particular problems arise when instead of steam abrasive suspensions, such as bauxite suspensions be sent through the pressure reducing valve. After a short time is not the pressure reduction due to the high wear rate sufficient and can no longer enter the specified setpoint hold.
Aufgabe der vorliegenden Neuerung ist es die beschriebenen Nachteile zu vermeiden und ein Druckreduzierventil für aggressive Suspensionen zu schaffen, das eine höhere Standzeit bei gleichzeitiger Wartungsfreundlichkeit ermöglicht.The task of the present innovation is that described Avoid disadvantages and a pressure reducing valve for to create aggressive suspensions that have a longer service life while maintaining ease of maintenance.
Die Aufgabe wird neuerungsgemäß durch die in den Schutzan sprüchen angegebenen Merkmale gelöst. Ein Beispiel wird anhand der Figur im folgenden näher erläutert:The task is renewed by those in the protection characteristics specified resolved. An example is given the figure explained in more detail below:
Im Kugelgehäuse 1 sind zwei axial gegenüberliegende Flansche 6, 7 angeordnet, die die Lagerung 8, 9 der Düsennadel 3 aufnehmen. Die abschraubbare Spitze 4 der Düsennadel 3 ragt in das zylinderförmige Drosselgehäuse 2 hinein, an dessen Ende die Drossel 5 angeordnet ist. Dabei ist der Durchmesser der Drossel 5 stets größer als der in sie hineinragende Durch messer der Düsennadel 3 bzw. ihrer Spitze 4. Dies soll einen vollständigen Verschluß des Druckreduzierventils verhindern.In the ball housing 1 , two axially opposite flanges 6 , 7 are arranged which accommodate the bearings 8 , 9 of the nozzle needle 3 . The unscrewable tip 4 of the nozzle needle 3 protrudes into the cylindrical throttle housing 2 , at the end of which the throttle 5 is arranged. The diameter of the throttle 5 is always larger than the diameter of the nozzle needle 3 or its tip 4 protruding into it. This is to prevent the pressure reducing valve from being completely closed.
Die Suspension strömt über den Einlaß 10 in das Kugelgehäuse 1 und von dort über den Flansch 6 in das Drosselgehäuse 2 und die Drossel 5 ein. Die Düsennadel 3 wird über einen Stellmotor (nicht dargestellt) in axialer Richtung verschoben, wodurch der Drosselquerschnitt, gemessen zwischen der Spitze 4 der Düsennadel und der Wandung der Drossel 5 verändert wird. Das Steuersignal für den Stellmotor wird über einen Druckgeber (nicht dargestellt) am Ausgang der Drossel 5 entnommen. Es ist auch möglich, das Steuersignal vor dem Kugelgehäuse 1 zu entnehmen, um den Druck an dieser Stelle zu regeln.The suspension flows through the inlet 10 into the ball housing 1 and from there via the flange 6 into the throttle housing 2 and the throttle 5 . The nozzle needle 3 is displaced in the axial direction via a servomotor (not shown), as a result of which the throttle cross section, measured between the tip 4 of the nozzle needle and the wall of the throttle 5 , is changed. The control signal for the servomotor is taken from a pressure sensor (not shown) at the output of the throttle 5 . It is also possible to take the control signal in front of the ball housing 1 in order to regulate the pressure at this point.
