Description

Die vorliegende Erfindung betrifft eine weitere Ausbildung von Druckminderern nach Patent 517472, bei denen außer der zur Entlastung dienenden Wellrohrmembran eine zweite Wellrohrmembran im Niederdruckraum angeordnet ist. Erfindungsgemäß ist diese zweite Membran unmittelbar an der Ventilspindel befestigt. Hierdurch wird der Vorteil erreicht, daß durch Wegfall des Übertragungshebels die Reibung in den Lagerstellen fortfällt und der Ventilkegel bereits durch die kleinsten auf die Wellrohrmembran wirkenden Drücke verstellt wird, wodurch sich eine erhöhte Empfindlichkeit und Genauigkeit des Ventils ergibt.The present invention relates to a further embodiment of pressure reducers Patent 517472, in which, in addition to the A second corrugated pipe membrane in the low-pressure chamber is used to discharge the corrugated pipe membrane is arranged. According to the invention, this second membrane is attached directly to the valve spindle. This will make the The advantage achieved is that the elimination of the transmission lever reduces the friction in the bearing points disappears and the valve cone already acts through the smallest on the corrugated pipe membrane Pressures are adjusted, resulting in increased sensitivity and accuracy of the valve results.

Der Erfindungsgegenstand ist im Schnitt schematisch dargestellt. Die Zeichnung zeigt die unmittelbare Verbindung der im Niederdruckraum angeordneten Wellrohrmembran mit dem Ventilkegel.The subject matter of the invention is shown schematically in section. The drawing shows the direct connection of the corrugated pipe membrane arranged in the low-pressure chamber with the valve cone.

Der Ventilkegel α ist durch die Ventilspindel b mit der Wellrohrmembran c starr verbunden, um den Druck auf den Ventilkegel mit dem gleich großen Druck auf die WeIlrohrmembran aufzuheben. Die Wellrohrmembran I ersetzt an der Ventilspindel b die Stopfbuchse, um die mechanische Reibung zu vermeiden, und ist mit der Wellrohrmembran m starr verbunden. Die Einstellungsschraube η drückt die Feder ο auf die Membran m und bewirkt das Öffnen des Ventils.The valve cone α is rigidly connected to the corrugated tube membrane c by the valve spindle b in order to release the pressure on the valve cone with the same pressure on the corrugated tube membrane. The corrugated pipe membrane I replaces the stuffing box on the valve spindle b in order to avoid mechanical friction and is rigidly connected to the corrugated pipe membrane m. The adjustment screw η presses the spring ο onto the membrane m and causes the valve to open.

Die Wirkungsweise des Ventils ist folgende: Durch den eingestellten Druck der Feder 0 auf die Wellrohrmembran m wird der Ventilkegel α mittels Ventilspindel b nach oben gedruckt und verursacht das öffnen des Ventils. Das Ventil bleibt so lang geöffnet, als der Niederdruck auf den Ventilkegel α plus dem Druck auf die Wellrohrmembran m kleiner ist als der Gegendruck durch die Feder o. Steigt jedoch der Niederdruck höher als der eingestellte Druck durch die Feder, so wirkt ,der Druck sowohl auf den Ventilkegel a als auch auf die Wellrohrmembran m, um ein sofortiges Drosseln oder Schließen des Ventils zu bewirken. Da Ventilkegel und Wellrohrmembran m durch die Ventilspindel starr verbunden sind, kann ein Verzögern des Ventilkegels beim Schließen bzw. Öffnen nicht eintreten.The valve works as follows: The set pressure of the spring 0 on the corrugated pipe membrane m pushes the valve cone α upwards by means of the valve spindle b and causes the valve to open. The valve remains open as long as the low pressure on the valve cone α plus the pressure on the corrugated tube membrane m is less than the counter pressure from the spring o. However, if the low pressure rises higher than the pressure set by the spring, the pressure acts both on the valve cone a as well as on the corrugated tube membrane m in order to effect an immediate throttling or closing of the valve. Since the valve cone and the corrugated pipe membrane m are rigidly connected by the valve spindle, the valve cone cannot be delayed when it is closed or opened.

Das Ventil kann derart gebaut sein, daß die Wellrohrmembran m für Dampf, Gas oder Flüssigkeit geeignet und auswechselbar angeordnet ist.The valve can be constructed in such a way that the corrugated tube membrane m is suitable for steam, gas or liquid and is arranged to be exchangeable.
