Description
Vorliegende Erfindung betrifft einenThe present invention relates to one
Druckregler mit Servomotor zur Speisung eines Reservoirs und für Konstanthaltung des Druckes innerhalb einstellbarer Grenzen in demselben dienend.Pressure regulator with servo motor for supplying a reservoir and keeping it constant of pressure within adjustable limits serving in the same.
Zur Lösung dieser Aufgabe hat man sich bisher eines vor und hinter dem Hauptventil angeschlossenen Relais bedient, das mittels Membran oder durch Kolben bewegte Ventile ίο oder Differenzialsteuerkolben den Servomotor betätigt, bei dem die für einen Druckregler nötige Druckdifferenz nicht beliebig gewählt werden kann.To solve this problem, one has previously had one in front of and behind the main valve connected relay operated, the valve moved by means of a membrane or piston ίο or differential control piston actuates the servomotor, in which the for a pressure regulator necessary pressure difference cannot be chosen arbitrarily.
Um obigen Zweck zu erreichen, wird ein Ventil oder Schieber, welcher den Durchfluß eines Mediums regelt, durch ein hinter dem Ventil angeschlossenes beliebig einstellbares Relais gesteuert.In order to achieve the above purpose, a valve or slide, which the flow of a medium is controlled by a freely adjustable one connected downstream of the valve Relay controlled.
In der Abbildung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes schematisch dargestellt.The figure shows an example of an embodiment of the subject matter of the invention shown schematically.
Der Raum unter dem Steuerkolben 1 steht mit der Sekundärleitung 2 stets in Verbindung. Ist nun der gewünschte Maximaldruck in der Sekundär leitung erreicht, so wird der Steuerkolben 1 gehoben, das Medium gelangt durch den Kanal 3 unter den Steuerkolben 4, drückt diesen nach oben, öffnet dadurch den Druckausgleichkanal 5 und verbindet die Leitungen 6 und 7 miteinander.The space under the control piston 1 is always connected to the secondary line 2. If the desired maximum pressure has now been reached in the secondary line, the Control piston 1 raised, the medium passes through channel 3 under control piston 4, pushes it upwards, thereby opening the pressure equalization channel 5 and connecting the Lines 6 and 7 together.
Das Medium strömt somit durch die Leitung 7 in den Raum über dem Kolben 8 und drückt diesen nach unten. Mittels Kolbenstange 9 wird das Ventil oder der Schieber 10 geschlossen, und das Medium kann nicht mehr durchströmen. Sinkt nun der Druck in der Sekundär leitung 2 um einen Bruchteil einer Atmosphäre, so geht der angehobene Steuerkolben 1 in seine untere Stellung zurück. Diese Bewegung hat aber noch kein Öffnen des Ventils oder des Schiebers 10 zur Folge, da der Druck unter dem Steuerkolben 4 durch Zuströmen des Mediums durch den Druckausgleichkanal 5 erhalten bleibt.The medium thus flows through the line 7 into the space above the piston 8 and pushes this down. The valve or slide 10 is opened by means of the piston rod 9 closed, and the medium can no longer flow through. If the pressure drops in the secondary line 2 by a fraction of an atmosphere, so goes the raised Return control piston 1 to its lower position. But this movement still has none Opening of the valve or the slide 10 results in the pressure under the control piston 4 is maintained by the flow of the medium through the pressure equalization channel 5.
Erst wenn der Druck auf das gewünschte *5 Minimum gesunken ist, so geht der durch das Gewicht entsprechend belastete Steuerkolben 4 wieder in seine unterste Stellung zurück, schließt den Druckausgleichkanal 5 ab und verbindet die Leitungen 7 und 11 miteinander, worauf das über dem Kolben 8 befindliche Medium ins Freie ausströmen kann.Only when the pressure on the desired * 5 Minimum has decreased, the control piston 4, which is correspondingly loaded by the weight, goes back to its lowest position, closes the pressure equalization channel 5 and connects the lines 7 and 11 to one another, whereupon the one above the piston 8 Medium can flow out into the open.
Die Feder 12 öffnet nun das Ventil oder den Schieber 10, und das Medium kann wieder durchströmen.The spring 12 now opens the valve or the slide 10, and the medium can again flow through.
Minimum und Maximum können unabhängig voneinander beliebig gewählt werden.Minimum and maximum can be chosen independently of each other.
