Druckminderventil.
Bei Druckminderventilen, die mit Membran und Flüssigkeitsbelastung arbeiten, kann die Genauigkeit der Regelung verbessert werden, wenn gemäss der Erfindung die nachfolgend beschriebenen Anordnungen getroffen werden.
EMI1.1
reduzierten Druckes ungünstige Umstand kann vermieden werden, wenn man den Flüssigkeitsbehälter B nicht starr, sondern nachgiebig befestigt und den obersten Teil des Druckröhrehens D als leicht bewegliches Verbindungsstück zum Behälter, z. B. als Gummi-oder als Metallschlauch, ausführt. Wird nun, z. B.
EMI1.2
Die nachgiebige Befestigung des Behälters B kann entweder darin bestehen, dass, wie in der Figur angegeben, eine Spiralfeder F die Unterlage bildet oder dass der Behälter federnd aufgehängt wird. Schliesslich ist es auch möglich, den Behälter B als offenen Schwimmer auszubilden, der bei der Gewichtszunahme infolge der von der Membran verdrängten Flüssigkeit nach unten sinkt. Die Spiralfeder F kann so bemessen werden, dass entweder die Entfernung der beiden Flüssigkeitsspiegel und konstant bleibt oder dass dieselbe in der Weise verändert wird, dass es möglich ist, Widerstände, die von der Stellung des Regelorganes R abhängig sind und von der unvollkommenen Entlastung desselben oder von der Steifheit der Membrane herrühren, möglichst weitgehend auszugleichen.
Dies kann z. B. in der Weise geschehen, dass dem Behälter B die Folm eines Rotationskörpers gegeben wird, dessen Meridianlinie empirisch für jede bestimmte Ausführungstype des Ventils ermittelt wird. Nach der Figur wird als Druckflüssigkeit Quecksilber Q verwendet, das nicht direkt auf die Membran wirkt, sondern durch ein Wasserkissen W von dieser getrennt ist.

Pressure reducing valve.
In the case of pressure reducing valves which work with a membrane and a liquid load, the accuracy of the regulation can be improved if the arrangements described below are made according to the invention.
EMI1.1
Reduced pressure unfavorable circumstance can be avoided if the liquid container B is not rigidly but flexibly attached and the uppermost part of the pressure tube D as an easily movable connection piece to the container, for. B. as a rubber or metal hose. If now, z. B.
EMI1.2
The flexible fastening of the container B can consist either in that, as indicated in the figure, a spiral spring F forms the base or in that the container is resiliently suspended. Finally, it is also possible to design the container B as an open float which, as the weight increases, sinks downwards as a result of the liquid displaced by the membrane. The spiral spring F can be dimensioned in such a way that either the distance between the two liquid levels and remains constant or that the same is changed in such a way that it is possible to create resistances that are dependent on the position of the control element R and on the incomplete relief of the same or originate from the stiffness of the membrane, compensate as much as possible.
This can e.g. B. done in such a way that the container B is given the folm of a body of revolution whose meridian line is empirically determined for each specific type of design of the valve. According to the figure, the pressure fluid used is mercury Q, which does not act directly on the membrane, but is separated from it by a water cushion W.
