E. WÜSTENFELD in MÜNDEN. Niederschraubventil mit Konusdichtung.E. DESERT FIELD in MÜNDEN. Screw-down valve with cone seal.
Patentirt im Deutschen Reiche vom 20. März 1878 ab.Patented in the German Empire on March 20, 1878.
Die Construction ist hinsichtlich des Ventiles selbst die gewöhnlich gebräuchliche, dagegen besteht das Neue der Einrichtung darin, dafs das Auf- und Zuschrauben nicht mittelst der Schraube, sondern mittelst Umdrehung der Mutter bewerkstelligt wird und dafs diese mittelst eines von innen anschliefsenden Konus a gedichtet wird.With regard to the valve itself, the construction is the usual one, but the novelty of the device consists in the fact that the screwing is not done by means of the screw, but by turning the nut, and that this is sealed by means of a cone a attached from the inside.
Es leuchtet ein, dafs durch Vermehrung des Druckes dieser Konus sowohl wie das Ventil selbst stärker auf ihre Sitze geprefst werden und dadurch ein Undichtwerden unmöglich ist.It is evident that by increasing the pressure this cone as well as the valve themselves are pressed harder on their seats and thus a leak is impossible.
Das Patent erstreckt sich demnach auf alle Ventile, Wasser- und Dampfschieber, bei denen seither Stopfbüchsen üblich waren.The patent therefore extends to all valves, water and steam valves where since then stuffing boxes have been common.
Um nun auch bei geöffnetem Ventil den Konus auf seinem Sitze zu erhalten, ist die Feder b angebracht, welche denselben stets anzieht. In order to keep the cone on its seat when the valve is open, the spring b is attached, which always attracts the same.
Die mit Schraube verbundene kleine Stange c dient dazu, um äufserlich sehen zu können, ob das Ventil offen oder geschlossen ist, doch wird diese Einrichtung nicht als wesentlich betrachtet.The small rod c connected by screw is used to externally see whether the valve is open or closed, but this device is not considered essential.
