Description

Vorrichtung zur Regelung des Preßwassers zum Betriebe von Großkraftschleifern zur Erzeugung von Holzschliff. Bei der Vorrichtung nach Patent 368785 wird zur Regelung des Preßwassers der zur Erzeugung von Holzschliff dienendem Schleifer eine durch die Kraftmaschine angetriebene Flüssigkeitspumpe dazu benutzt, einen mit der wechselnden Belastung der Kraftmaschine sich ändernder Flüssigkeitsdruck zu erzeugen, wodurch das Einstellen des Ventilstiftes des Preßwasserreglerventils herbeigeführt wird. Die vorliegende Erfindung bietet die Möglichkeit, unmittelbar das Triebmittel der Kraftmaschine zur Einstellung des Ventilstiftes des Preßwasserreglerventils nutzbar zu machen.Device for regulating the press water for the operation of large power grinders for the production of wood pulp. In the device according to patent 368785 for regulation of the press water of the grinder used to produce wood pulp one through the prime mover powered fluid pump used to one with the alternating Load on the engine to produce changing fluid pressure, thereby the adjustment of the valve pin of the press water regulator valve is brought about. The present invention offers the possibility of directly using the propellant Power machine can be used to adjust the valve pin of the press water regulator valve close.

Es wird dies dadurch ermöglicht, daß als Kraftmaschine zum Antrieb des. Schleifers eine Dampfturbine verwendet wird und der Zylinder, in dem der den Ventilstift tragende Kolben verstellt wird, durch eine Leitung an den hinter dem Drosselventil der Turbine befindlichen Dampfraum angeschlossen ist.This is made possible by the fact that the drive is used as a prime mover des. Grinder a steam turbine is used and the cylinder in which the Piston bearing the valve pin is adjusted through a line to the behind the Throttle valve of the turbine located steam space is connected.

Da der in diesem Rainme herrschende Dampfdruck je nach der stärkeren oder schwächeren Belastung der Turbine schwankt, so wechselt der Druck, der auf den den Ventilstift tragenden Kolben ausgeübt wird, in genau entsprechendem Maße. Demgemäß wird auch die Feder, die diesen Kolben und damit den Ventilstift vom Ventilsitz ständig entfernt zu halten trachtet, mehr oder weniger stark gespannt und hierdurch der Durchflußquerschnitt im Preßwasserreglerventil entweder verringert oder vergrößert, so daß auch der Schleifer entsprechend mehr ent- oder belastet wird.As the vapor pressure prevailing in this rainme depends on the stronger or weaker load on the turbine fluctuates, so the pressure that changes the piston carrying the valve pin is exerted to exactly the same extent. Accordingly, the spring, this piston and thus the valve pin from the valve seat constantly strives to keep away, more or less tense and thereby the flow cross-section in the pressurized water control valve is either reduced or increased, so that the grinder is correspondingly more relieved or burdened.

In der Zeichnung ist eine Ausführung der neuen Reglervorrichtung dargestellt.The drawing shows an embodiment of the new regulator device.

Der Ventilstift 2 des Preßwasserreglerventils z trägt in bekannter Weise einen in einem Zylinder q. abgedichteten Kolben 3, den eine Schraubengangfeder 5 nach oben zu schieben und so ständig vom Ventilsitz entfernt zu halten trachtet. Der über dem Kolben: 3 befindliche Raum des Zylinders q. ist durch die Dampfleitung 6 an den hinter dem Drosselventil 7 -der Dampfturbine 8 befindlichen Dampfraum angeschlossen. Das Drosselventil wird in an sich bekannter Weise vom Regler g aus gesteuert.The valve pin 2 of the press water regulator valve z carries in known Way one in a cylinder q. sealed piston 3, which is a helical spring 5 upwards and thus constantly seeks to keep it away from the valve seat. The space of the cylinder q located above the piston: 3. is through the steam pipe 6 connected to the steam space located behind the throttle valve 7 -the steam turbine 8. The throttle valve is controlled in a manner known per se from the controller g.

Die hierdurch im Dampfraum der Turbine hervorgerufenen Druckschwankungen pflanzen sich durch die Leitung 6 bis in den Zylinder d: fort und veranlassen in Verbindung mit dem Einfluß der Feder 5 je nach Zu- oder Abnahme des in der Turbine herrschenden Dampfdruckes eine Ab- oder Aufwärtsbewegung des Ventilstiftes 2 und damit eine Verringerung oder Vergrößerung des Durchflußquerschnittes im Reglerventil i, was dann eine entsprechende Ab- oder Zunahme der Belastung des Schleifers zur Folge hat.The resulting pressure fluctuations in the steam space of the turbine propagate through the line 6 to the cylinder d: and cause in Connection with the influence of the spring 5 depending on the increase or decrease in the turbine prevailing steam pressure a downward or upward movement of the valve pin 2 and thus a reduction or increase in the flow cross-section in the regulator valve i, which then results in a corresponding decrease or increase in the load on the grinder Consequence.

Es ist gleichgültig, an welcher Stelle des Turbinengehäuses der den Kolben 3 beeinflussende Dampf entnommen wird; so kann z. B. bei sogenannten Anzapfturbinen der in der Anzapfleitung vorhandene, sich ebenfalls nach der Belastung richtende Dampfdruck zur Steuerung des Ventilstiftes benutzt werden.It does not matter at which point of the turbine housing the den Piston 3 influencing steam is removed; so can z. B. in so-called bleed turbines the one present in the tap line, which is also based on the load Steam pressure can be used to control the valve pin.
