Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die bisher z. B. bei Centralheizungen verwendeten Regulirventile sind entweder von nicht zu vermeidenden Fehlern behaftet (z. B. Festbrennen der Regulirvorrichtung) oder ihre Herstellung ist kostspielig.The previously z. B. Regulirventile used in central heating are either of unavoidable faults (e.g. sticking of the regulating device) or their Manufacturing is costly.
Diese Nachtheile sollen durch das den Gegenstand der Erfindung bildende Ventil beseitigt werden. Dasselbe besteht aus dem Gehäuse A, in welchem sich die beiden auf einander stehenden Spindelglieder B und C befinden. Dieselben sind durch die verstellbare Schraube D verbunden. Letztere kann durch die Gegenmutter E gegen ein selbstthä'tiges Verstellen geschützt werden.These disadvantages are intended to be eliminated by the valve forming the subject of the invention. The same consists of the housing A , in which the two spindle members B and C standing on top of one another are located. They are connected by the adjustable screw D. The latter can be protected against automatic adjustment by the lock nut E.
Erweist sich nun die durch das Ventil strömende Menge als zu grofs, so wird das Ventil geschlossen und die Schraube D (dem Bedarf entsprechend) nach unten geschraubt. Hierdurch entsteht zwischen dieser und dem bisher auf ihr ruhenden Bund des Spindelgliedes C ein Zwischenraum. Wird jetzt das Ventil wieder geöffnet, so kann die untere Spindel nicht direct hochgezogen werden, ihr Hub wird infolge dessen vermindert und' die Oeffnung im Ventilsitz bleibt theilweise versperrt. Durch den Druck der Dichtungmasse F und der zwischen den beiden Spindelgliedern angebrachten schraubenförmigen Feder G wird ein selbstthätiges Heben durch den Druck der Leitung vermieden.If the amount flowing through the valve turns out to be too large, the valve is closed and screw D is screwed down (as required). This creates an intermediate space between this and the collar of the spindle member C, which was previously resting on it. If the valve is now opened again, the lower spindle cannot be pulled up directly, its stroke is reduced as a result, and the opening in the valve seat remains partially blocked. Due to the pressure of the sealing compound F and the helical spring G attached between the two spindle members, an automatic lifting due to the pressure of the line is avoided.
Ein Festbrennen der Regulirvorrichtung ist unmöglich, weil dieselbe aufserhalb des Dampfbereiches sich befindet.Burning of the regulating device is impossible because it is outside the steam range located.
