Diese Vorrichtung zur Regelung des Druckes von Gasen aller Art zeichnet sich vor ähnlichen Vorrichtungen darin aus, dafs die Empfindlichkeit gegen Druckschwankungen sehr grofs ist, dafs ferner der Druck mit grofser Leichtigkeit verstellt und auf jede beliebige Höhe eingestellt werden kann, und dafs der einmal eingestellte Druck stets dieselbe Gröfse behält, da Federn und solche elastischen Körper, welche mit der Zeit ihre Elasticität einbüfsen, hier nicht verwendet werden. Als besonderer Vorzug ist noch die sichere Führung des Ventils und die einfache Construction hervorzuheben. This device for regulating the pressure of gases of all kinds is distinguished from similar ones Devices in that the sensitivity to pressure fluctuations is very high it is great that furthermore the pressure can be adjusted with great ease and on any arbitrary Height can be adjusted, and that once the pressure is set, it is always the same retains, since springs and such elastic bodies, which lose their elasticity over time, not used here. As a particular advantage, the safe guidance of the valve and the simple construction should be emphasized.
Die Vorrichtung ist im Durchschnitt, Fig. 1, in der Seitenansicht, Fig. 2, und im Grundrifs, Fig. 3, dargestellt. Sie besteht im wesentlichen aus zwei Hohlräumen A und B, welche durch eine nachgiebige und federnde Plätte S von einander geschieden sind. In den unteren Hohlraum reicht ein Kolben D hinein, welcher mittelst der Stopfbüchse E nach aufsen abgedichtet ist. Der Kolben läfst sich mittelst Gewindes und eines Handrädchens F mehr oder weniger tief in die Kammer A hineindrücken. Eine Mutter H verhütet das unbeabsichtigte Verstellen des Kolbens. Ein Manometer R zeigt den Druck an, welcher in dem zweckmäfsig mit einem Gemenge eines Gases mit einer tropfbaren Flüssigkeit gefüllten Hohlraum A herrscht.The device is shown in the cross section, FIG. 1, in the side view, FIG. 2, and in the outline, FIG. 3. It consists essentially of two cavities A and B, which are separated from one another by a flexible and resilient plate S. In the lower cavity a piston extends into D, which by means of the gland by E aufsen is sealed. The piston can be pushed more or less deeply into the chamber A by means of a thread and a handwheel F. A nut H prevents unintentional adjustment of the piston. A manometer R indicates the pressure which prevails in the cavity A , which is expediently filled with a mixture of a gas with a drip liquid.
In den oberen Hohlraum B führt der Rohrstutzen O, welcher mit Gewinde und Kappe Q. zum Anschlufs eines Rohres P versehen ist.The pipe socket O, which is provided with a thread and a cap Q for connecting a pipe P, leads into the upper cavity B.
Ein zweiter Rohransatz N trägt die Gewindekappe M, in welcher die hohle und mit Handrädchen W versehene Rohrschraube K sich verstellen läfst. Durch eine Stopfbüchse wird' auch hier eine Abdichtung zwischen JY M und K erzielt. Das Rohr K ist unten kegelförmig ausgedreht und bildet einen Sitz V für das Ventil X, dessen Stange / in der Platte S befestigt ist.A second pipe extension N carries the threaded cap M, in which the hollow pipe screw K provided with handwheels W can be adjusted. Here, too, a seal between JY M and K is achieved by means of a stuffing box. The tube K is turned out in a conical shape at the bottom and forms a seat V for the valve X, the rod / of which is fastened in the plate S.
Tritt Gas von P aus in den Hohlraum B, so kann es nur dann durch K entweichen, wenn sein Druck höher als der im Hohlraum A ist. Im letzteren Falle prefst die abwärts gehende Platte S die Luft in A zusammen, das Ventil öffnet sich, und das Gas entweicht mit derselben Spannung wie in A so lange, als der Druck in B den in A herrschenden übertrifft. Genaue Einstellung des Ventils kann mit Hülfe der Schraube K bewirkt werden.If gas enters cavity B from P , it can only escape through K if its pressure is higher than that in cavity A. In the latter case, the downward moving plate S compresses the air in A , the valve opens, and the gas escapes with the same voltage as in A as long as the pressure in B exceeds that in A. Exact adjustment of the valve can be effected with the help of the screw K.
