Description

Mit Schwimmer arbeitender Druckminderer Den Gegenstand der Erfindung bildet ein mit Schwimmer ,arbeitender Druckminderer, bei dem die Einstellung der Höhe des gewünschten Minderdrucks durch Verschieben eines das überlaufg-efäß tragenden Standrohres erfolgt.Pressure reducer working with float The subject of the invention forms a pressure reducer working with a float, in which the adjustment of the Level of the desired reduced pressure by moving a Standpipe takes place.

Bei den bisher bekanntgewordenen Ausführungen dieser Art liegt die Durchtrittsstelle des Standrohres aus dem Druckmindergefäß im Bereich der Steuerflüssigkeit. Demzufolge tritt beim Verstellen des Standrohres sowie beim Undichtwerden der Verschraubung während des Betriebes die unter Druck stehende Steuerflüssigkeit aus der Verschraubung aus und geht unter Umständen restlos verloren. Das ist bei Verwendung von Glycerin, Quecksilber ö. dgl. als Steuerflüssigkeit kostspielig; außerdem wird dadurch die Einstellung des Standrohres zur genauen Regelung der Druckminderung erschwert.In the versions of this type that have become known so far, the Passage point of the standpipe from the pressure reducing vessel in the area of the control fluid. As a result, when the standpipe is adjusted and the screw connection leaks the pressurized control fluid out of the screw connection during operation and may be completely lost. This is when using glycerine, Mercury or the like as a control fluid is expensive; it also makes the Adjustment of the standpipe for precise regulation of the pressure reduction is difficult.

Die Erfindung vermeidet diese Nachbeile, indem sie die Durchtrittsstelle des Standrohres aus dem Druckmindergehäüse oberhalb des den Schwimmer bewegenden Spiegels der Steuerflüssigkeit vorsieht.The invention avoids these problems by eliminating the point of passage of the standpipe from the pressure reducer housing above the one moving the float Provides the level of the control fluid.

In der Zeichnung ist als Beispiel ein derart ausgebildeter Druckminderer im Längsschnitt dargestellt.A pressure reducer designed in this way is shown as an example in the drawing shown in longitudinal section.

Der hohe Drück des bei i in das Ventil gehäuse 2 eintretenden Mediums, wie Dampf oder Gas, wird in bekannter Weise beim Durchtritt durch das Ventil 3, ,also beim Ein:-tritt in das Gehäuse 4, entsprechend dein jeweiligen C)ffnungsquerschnitt des Ventils gemindert und über den Rohrstutzen 5 entnomm-en. Die Regelung der Druckminderung, also die Einstellung des Öffnungsquerschnittes des Ventils 3, ,erfolgt dabei in Abhängigkeit von der Stellung eines Schwimmers 6, dessen Auftrieb durch ein Rohr 7 vermittels einer am Kopf des letzteren vorgesehenen Gabel 8 auf den im Punkt 9 drehbar gelagerten Hebel io übertragen wird, an dem auch die Ventilspindel i i .angreift. Dass Rohr 7 durchdringt den Schwimmer 6, und innerhalb des Rohres 7 ist das Standrohr 12, welches das fTberlaufgefäß 13 trägt, vorgesehen. Das Standrohr ist also im Druckmindergehäuse unten geführt und tritt durch dessen obere Wandung hindurch. Die dort erforderliche Verschraubung bzw. Dichtung 14 liegt also außerhalb des Bereichs der Steuerflüssigkeit, so daß dort keine Steuerflüssigkeit *austreten kann, selbst wenn die Verschraubung während des Betriebes undicht werden sollte. Das Standrohr bildet gleichzeitig die Führung für den Schwimmer.The high pressure of the medium entering the valve housing 2 at i, such as steam or gas, is in a known manner when passing through the valve 3, , i.e. when entering the housing 4, according to your respective opening cross-section of the valve and removed via the pipe socket 5. The regulation of the pressure reduction, so the setting of the opening cross-section of the valve 3,, takes place in Depending on the position of a float 6, its buoyancy through a pipe 7 by means of a fork 8 provided on the head of the latter on the point 9 rotatably mounted lever io is transmitted, on which the valve spindle i i .attacks. The pipe 7 penetrates the float 6, and inside the pipe 7 is the standpipe 12, which carries the overflow vessel 13, is provided. The standpipe is in the pressure reducer housing out below and passes through its upper wall. The one required there Screw connection or seal 14 is therefore outside the range of the control fluid, so that no control fluid * can escape there, even if the screw connection should leak during operation. The standpipe also forms the Guide for the swimmer.
