KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist ein Durchflußregler, bei welchem die Regelung durch einen Dorn bewirkt wird, der in einem besonderen Abschlußventilkörper verstellbar angeordnet ist und in die Durchflußöffnung des Ventilsitzes eindringt. Von den bisher bekannt gewordenen Einrichtungen dieser Art unterscheidet sich dieser Durchflußregler dadurch, daß sich die Durchflußöffnung in der Richtung des in sie eindringenden Dornes allmählich verjüngt. Hierdurch wird es möglich, den Durchflußquerschnitt beim Absperren des Ventils je nach der Form des Dornes und dessen Einstellung im Niederschraubventilkörper in den weitgehendsten Grenzen verändern zu können.The present invention is a flow controller in which the regulation is effected by a mandrel which is adjustably arranged in a special shut-off valve body is and penetrates into the flow opening of the valve seat. Of those known so far devices of this type that have become established, this flow regulator differs in that that the flow opening gradually in the direction of the penetrating mandrel rejuvenates. This makes it possible to reduce the flow cross-section when shutting off the valve depending on the shape of the mandrel and its setting in the screw-down valve body in the to be able to change the most extensive limits.
Die Zeichnung zeigt in den Fig. 1, 4 und 5The drawing shows in FIGS. 1, 4 and 5
Ausführungsformen des Durchflußreglers und in den Fig. 3 und 3 verschiedene Einstellungen des Ventils und des in demselben verschraubbaren Dornes.Embodiments of the flow regulator and in Figs. 3 and 3 different settings of the valve and the mandrel that can be screwed into the same.
Aus den Figuren geht ohne weiteres hervor, daß der mit dem Ventilkörper α nach abwärts gehende Dorn b bezw. b" b'" den Durchgang in dem sich verjüngenden Rohranschluß c bezw. C1 des Ventilsitzes um so langsamer verengt, je mehr sich die Form des Dornes derjenigen des besagten Rohranschlusses nähert, was bei Verwendung eines konischen Dornes in zylindrischer Durchflußform des Sitzes bezw. Rohranschlusses nicht erreichbar ist. Auch läßt es sich erreichen, daß, falls der Dorn ebenfalls eine verjüngte Form erhält, bei bestimmter Einstellung desselben zum Ventilkörper a die durch den Dorn bewirkte Verengung des Durchflußquerschnittes beim Abwärtsbewegen des Ventilkörpers α nahezu konstant bleibt.From the figures it can readily be seen that the mandrel b respectively downward with the valve body α. b "b '" the passage in the tapered pipe connection c respectively. C 1 of the valve seat narrows the slower the closer the shape of the mandrel approaches that of the said pipe connection, which BEZW when using a conical mandrel in a cylindrical flow shape of the seat. Pipe connection is not accessible. It can also be achieved that, if the mandrel is also given a tapered shape, when the mandrel is adjusted in a certain manner to the valve body a, the narrowing of the flow cross section caused by the mandrel remains almost constant when the valve body α is moved downwards.
Demnach gestattet die kegelartige Verengung der Durchflußöffnung c bezw. C1 alle nur denkbaren Genauigkeitsgrade der Durchflußregulierung, je nachdem die Form des Dornes, welche durch Versuche festgestellt werden kann, sich dieser Verengung der Öffnung mehr oder weniger anpaßt, so daß hierdurch den bekannten Durchflußreglern mit zylindrischer Durchflußöffnung gegenüber ein wesentlicher Vorteil erzielt wird.Accordingly, the cone-like narrowing of the flow opening c respectively allows. C 1 all conceivable degrees of accuracy of the flow regulation, depending on the shape of the mandrel, which can be determined by experiments, more or less adapts to this narrowing of the opening, so that this achieves a significant advantage over the known flow regulators with cylindrical flow openings.
