einer Regulirschraube ca regulating screw c
Das Ventil α wird durch eine Feder b, die
unter dem Einflüsse
steht, niedergedrückt.The valve α is by a spring b , which is under the influences
stands, depressed.
Das bei d unter Normaldruck einströmende Druckmittel (Dampf, Wasser," Gas etc.) bewirkt nun vor dem Austritt durch e unter dem Gegendrucke der Feder ein Heben des Ventilkörpers a. The pressure medium (steam, water, "gas, etc.)" flowing in at d under normal pressure now causes the valve body a to be lifted under the counterpressure of the spring before it exits through e .
Dieses Heben des Ventilkörpers und damit das Oeffnen des Durchganges wird dabei stets in umgekehrtem Verhältnis zum Gegendruck jener Feder sein.This lifting of the valve body and thus the opening of the passage is always done be in inverse proportion to the back pressure of that spring.
Soll nun zum Beispiel eine Ausströmung des Druckmittels mit stark vermindertem Druck herbeigeführt werden, so braucht man mittels der Schraube c nur den Federdruck zu steigern, derart, dafs der Ventilkörper die Durchströmung so drosselt, dafs nur eine geringe Menge des Druckmittels durchströmen kann, was eine bedeutende Verminderung der Spannung an der dem Einlaufe d entsprechend gleich grofsen Ausströmung e zur Folge hat.If, for example, an outflow of the pressure medium is to be brought about with greatly reduced pressure, then one only needs to increase the spring pressure by means of the screw c , in such a way that the valve body throttles the flow so that only a small amount of the pressure medium can flow through, which is a Significant reduction in the tension at which, corresponding to the inlet d , results in an outflow e of the same size.
Unter je mehr Druck nun die Ausströmung erfolgen soll, desto mehr verringert man den Federdruck dem Wasserdruck gegenüber.The more pressure the outflow is to take place, the more it is reduced Spring pressure versus water pressure.
Bei Einstellung des Betriebes kann das Ventil α mittels der Schraubenspindel g ganz auf den Ventilsitz niedergedrückt und damit der Durchgang abgesperrt werden. Dabei kann sich die vorher gespannte Feder b ausdehnen und so während der Betriebspausen ausruhen. Wird bei Wiederinbetriebsetzung die Spindel g hochgeschraubt, so tritt die Feder b sofort selbstthätig in Function und setzt dem Ventile beim Durchströmen des Druckmittels den früheren Widerstand entgegen. When the operation is stopped, the valve α can be pressed down completely on the valve seat by means of the screw spindle g, thus blocking the passage. The previously tensioned spring b can expand and so rest during breaks in operation. If the spindle g is screwed up when the system is restarted, the spring b automatically comes into operation immediately and opposes the previous resistance to the valve when the pressure medium flows through it.
