KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Dieses Ventil bezweckt gegenüber den üblichen Hähnen eine gröfsere Dauerhaftigkeit.The purpose of this valve is greater durability than conventional taps.
Der Konus α sowohl beim Wasserstandsventil, Fig. i, wie beim Ausblaseventil, Fig. 2, trägt an seinem äufseren Ende einen mit Gewinde versehenen Bolzen, der mit Handrad, Handgriff oder einer Vorrichtung zum Aufstecken eines Schlüssels versehen ist. Der Konus ist in die konische Ausbohrung c eingeschliffen. Durch entsprechende Drehung des Konus α ist man bei Wasserstandsgläsern im Stande, das durch Kanal b nach dem Wasserstandsglase d tretende Kesselwasser bezw. den Dampf abzusperren oder bei entgegengesetzter Drehung zuzulassen, sowie bei Ausblasevorrichtungen den Kesselinhalt durch Kanal b entweichen zu lassen.The cone α both in the water level valve, Fig. I, as in the blowout valve, Fig. 2, carries at its outer end a threaded bolt which is provided with a handwheel, handle or a device for attaching a key. The cone is ground into the conical bore c. By appropriate rotation of the cone α one is in a position with water level glasses, respectively the boiler water passing through channel b after the water level glasses d. to shut off the steam or to allow it in the opposite direction, as well as to allow the boiler contents to escape through channel b in the case of blow-out devices.
Da der Konus α länger als sein Sitz c ist und hinter dem Sitze noch ein freier Raum f sich befindet, so wird derselbe bei seiner wie seines Sitzes Abnutzung je nach Verhältnifs der Abnutzung etwas weiter in den Raum f eindringen, wobei die Dichtung erhalten bleibt.Since the cone α is longer than its seat c and there is still a free space f behind the seat, it will penetrate a little further into the space f when it is worn as well as its seat, whereby the seal is retained.
Der Kanal g dient dazu, das in den den Konus α umgebenden Raum eingedrungene Wasser und alle Unreinigkeiten entweichen zu lassen.The channel g is used to allow the water that has penetrated into the space surrounding the cone α and all impurities to escape.
