Description

Die Erfindung bezweckt, bei Doppelsitzventilen die bei Tempsraturschwankungen durch die ungleiche Ausdehnung des Ventilgehäuses und der Ventilspindel mit den Ventilkegeln hervorgerufenen Undichtigkeiten in \Ollkommenerer Weise, als es bisher möglich war, zu beseitigen. Die Erfindung besteht darin, daß die aus Rotguß ο. dgl. bestehenden Ventilkegel auf einer Spindel befestigt sind, deren Wärmeausdehnungskoeffizient etwa gleich dem des Yentilgehäuses ist.The invention aims at double seat valves with temperature fluctuations due to the unequal expansion of the valve housing and the valve spindle with the valve cones caused leaks in a more complete way than was previously possible was to eliminate. The invention consists in that the gunmetal ο. like. existing Valve cone are attached to a spindle, the coefficient of thermal expansion about is the same as that of the valve housing.

Die Zeichnung stellt den Erfindungsgegenstand in einem Ausführungsbeispiel dar. Die Ventilkegel α und 1; und die Ventilspindel c bilden verschiedene Stücke aus verschiedenem Material. Die Kegel α und b bestehen wie gewöhnlich aus Rotguß ο. dgl. und sind auf der Spindel c befestigt. Die Spindel c besteht aus einem Material, welches den gleichen Wärmeausdehnungskoeffizienten besitzt -n das aus Gußeisen bestehende \'Tentilgehäuse beispielsweise aus Temperguß.The drawing represents the subject matter of the invention in one embodiment. The valve cone α and 1; and the valve stem c form different pieces of different material. As usual, the cones α and b are made of red brass ο. Like. And are attached to the spindle c. The spindle c consists of a material which -n the same thermal expansion coefficient, which consists of cast iron \ 'T entilgehäuse for example, from malleable cast iron.

Hierdurch wird erreicht, daß bei Temp raturänderungen der Abstand zwischen d Ventilkegeln α und b sich in derselben Wei ändert wie der Abstand der Ventilsitze e unc und stets ein dichter Abschluß erzielt wird.This ensures that at temp temperature changes the distance between d valve cones α and b changes in the same way as the distance between the valve seats e unc and a tight seal is always achieved.
