Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist ein Druckminderventil mit Regelkörper. Bei den bekannten Druckminderventilen wird in kurzer Zeit der zur Drosselung dienende Regelkörper undicht, abgesehen davon, daß ein Festklemmen desselben durch etwa mitgerissene Schmutzteilchen leicht eintreten kann.The invention relates to a pressure reducing valve with a regulating body. With the known Pressure reducing valves, the regulating body used for throttling becomes leaky in a short time, apart from the fact that there is a jamming the same can easily enter through possibly entrained dirt particles.
Um diese Nachteile zu vermeiden, wird bei dem Erfindungsgegenstande die Druckminderung nicht durch den Regelkörper bewirkt, sondern das Druckmittel wird nach Passieren des Regelkörpers in einer besonderen Vorrichtung durch Drosselung oder Expansion auf die niedrigere Spannung gebracht.In order to avoid these disadvantages, the subject of the invention is the pressure reduction not caused by the control body, but the pressure medium is after passing of the regulating body in a special device by throttling or expansion brought to the lower voltage.
Der Erfindungsgegenstand ist auf der beiliegenden Zeichnung in Fig. 1 in einem Axialschnitt dargestellt; Fig. 2 und 3 zeigen Einzelheiten. The subject of the invention is shown in the accompanying drawing in FIG. 1 in an axial section shown; Figures 2 and 3 show details.
Das Ventil ist zweckmäßig mit nichtentlasteten oder entlasteten Ventilkörpern, Schiebern oder Kolben versehen, die den Zutritt des Druckmittels regeln.The valve is useful with unbalanced or balanced valve bodies, slides or pistons that regulate the admission of the pressure medium.
Bei der neuen Vorrichtung herrscht an beiden Seiten des Regelkörpers der gleiche Druck, da die Minderung des Druckes nicht durch den Regelkörper erfolgt, sondern durch Drosselung oder Expansion in der Drosselvorrichtung α, b, c, d bzw. den Düsen 1, 2, 3. Die Düsen 1, 2, 3 sind mit feinen Durchtritts-Öffnungen η versehen, durch die das Druckmittel gedrosselt wird.In the new device, the same pressure prevails on both sides of the regulating body, since the pressure is not reduced by the regulating body, but by throttling or expansion in the throttling device α, b, c, d or the nozzles 1, 2, 3. The nozzles 1, 2, 3 are provided with fine passage openings η through which the pressure medium is throttled.
Dadurch werden die Vorteile erzielt, daß der Regelkörper in einem Druckmittel von gleicher oder angenähert gleicher Spannung arbeitet, so daß bei einem Steigen des Druckes in der Niederdruckleitung, etwa infolge verminderter Entnahme, durch die Einwirkung des steigenden Druckes auf das regelnde Organ eine ganz genaue Regulierung möglich ist, daß ferner die in die Niederdruckleitung strömende Menge des Druckmittels nicht von dem freien Ventilquerschnitt bzw. Ventilhub abhängig ist. Wenn stets die gleiche Menge entnommen wird, so ist es nicht erforderlich, einen besonders die Zuströmung des Hochdruckdampfes regelnden Ventilkörper von der Niederdruckseite aus zu beeinflussen.This has the advantages that the control body is in a pressure medium of the same or approximately the same voltage works, so that when the pressure rises in the low-pressure line, for example as a result of reduced withdrawal, due to the action the increasing pressure on the regulating organ enables a very precise regulation is that, furthermore, the amount of pressure medium flowing into the low-pressure line is not of depends on the free valve cross-section or valve lift. If always the same amount is taken, it is not necessary, in particular, the inflow of high pressure steam to influence regulating valve body from the low-pressure side.
Die Vorrichtung kann dann so ausgeführt werden, daß gerade so viel Dampf in dieselbe hineintritt, wie in der Niederdruckleitung entnommen wird.The device can then be designed so that just that much steam flows into it enters, as is taken in the low pressure line.
