KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Kraftanlagen, in welchen ein in Rohrleitungen geführtes Triebmittel (Dampf, Gas, Luft, Wasser) zur Verwendung kommt, ist es sehr oft erforderlich, einem bei B angeschlossenen Apparat o. dgl. das Triebmittel von A aus nicht allein direkt (wie der ausgezogene Pfeil in Fig. ι und 2 andeutet) zuzuführen, sondern dasselbe zunächst durch einen anderen Apparat bei Z durchtreten zu lassen undIn power plants in which a propellant (steam, gas, air, water) carried in pipelines is used, it is very often necessary to not only direct the propellant from A to an apparatus or the like connected to B (like the one drawn out) Arrow in Fig. Ι and 2 indicates), but to let the same first pass through another apparatus at Z and
ίο dann erst nach B zu führen (Weg in Fig. ι und 2 punktiert) oder aber auch sowohl B wie Z ganz von A abzusperren.ίο then lead only to B (path in Fig. ι and 2 dotted) or also to block both B and Z completely from A.
Zu diesem Zweck waren bisher immer mehrere (bis zu vier) Ventile und zuweilen auch noch Rohrformstücke erforderlich, so daß infolgedessen eine ganze Reihe von Flanschenverbindungen als notwendiges Übel mit in den Kauf genommen werden mußte, ganz abgesehen von der Kostspieligkeit dieser Anordnung. Auch ist bisher keine Konstruktion bekannt geworden, welche es ermöglichte, in eine bereits vorhandene Leitung A-B einen neuen Apparat Z durch Einbau nur eines einzigen einhäusigen Umschaltventils von normaler Baulänge an Stelle eines bisherigen gewöhnlichen Absperrventils einzuschalten, so daß die vorhandene Leitung überhaupt nicht geändert zu werden brauchte.For this purpose, several (up to four) valves and sometimes pipe fittings have always been necessary, so that as a result a whole series of flange connections had to be accepted as a necessary evil, quite apart from the cost of this arrangement. Also, no construction has yet become known which made it possible to switch on a new apparatus Z in an existing line AB by installing only a single single-housing switch valve of normal length instead of a conventional shut-off valve so that the existing line cannot be changed at all needed.
Die in der Zeichnung dargestellte Erfindung zeigt ein Umschalt- (und zugleich Absperr-) ventil, welches an Stelle eines gewöhnlichen — immer vorhandenen — Ventils ohne weiteres in eine gegebene Leitung eingebaut werden kann und auch sonst für sich allein — ohne Zufügung anderer Ventile — die eingangs erwähnten drei erforderlichen Schaltungen ermöglicht. Denn wenn sich in Fig. ι beide Ventilkegel auf ihren äußeren Sitzen bei s befinden (wie gezeichnet), so ist die direkte Verbindung von A nach B hergestellt und gleichzeitig Z abgeschaltet. Ruhen beide Ventilkegel auf ihren inneren Sitzen bei t, so ist die punktiert gezeichnete Schaltung von A über Z nach B vorhanden; befindet sich drittens das untere Ventil auf seinem äußeren Sitz bei s und das obere Ventil auf seinem inneren Sitz bei t, so sind sowohl B als auch Z von A abgesperrt.The invention shown in the drawing shows a changeover (and at the same time shut-off) valve, which can be installed in place of an ordinary - always present - valve easily in a given line and otherwise on its own - without the addition of other valves - the three required circuits mentioned at the outset. Because if in Fig. Ι both valve cones are on their outer seats at s (as drawn), the direct connection from A to B is established and Z is switched off at the same time. If both valve cones rest on their inner seats at t, the dotted circuit from A via Z to B is available; Third, if the lower valve is on its outer seat at s and the upper valve is on its inner seat at t, both B and Z are shut off from A.
