Description
Luftausscheidungsvorrichtung bei Expansionsgefäßen Die Erfindung betrifft eine Vorrichtung für die Ausscheidung von Luft aus dem vom Expansionsgefäß zur angeschlossenen Anlage, z. B. einer Zentralheizungsanlage, geführten Wasser.Air Elimination Device in Expansion Vessels The invention relates to a device for the removal of air from the from the expansion vessel to the connected Plant, e.g. B. a central heating system, guided water.
Bei Zentralheizungsanlagen u. dgl. mit Expansionsgefäßen besitzt das Wasser, das vom Expansionsgefäß zur übrigen Anlage zurückgeführt wird, eine Tendenz, Luft mitzunehmen. Die Erfindung betrifft eine Vorrichtung, durch welche diese Luftmitnahme und die damit verbundenen Nachteile vermieden werden.In central heating systems and the like with expansion vessels, the Water returned from the expansion tank to the rest of the system has a tendency to To take air with you. The invention relates to a device through which this air entrainment and the associated disadvantages are avoided.
Die Erfindung zeichnet sich dadurch aus, daß in dem im Expansionsgefäß befindlichen Teil des Expansionsrohres mindestens eine Einschnürung vorgesehen ist und daß auf der Ablaßseite jeder Einschnürung, in der Zurückströmungsrichtung gesehen, ein Loch vorgesehen ist, durch welches frei gemachte Luft entweichen kann.The invention is characterized in that in the expansion vessel located part of the expansion pipe is provided at least one constriction and that on the outlet side of each constriction, seen in the backflow direction, a hole is provided through which released air can escape.
Die Einschnürung oder Einschnürungen sind zweckmäßig in einem waagerechten Teil des Expansionsrohres vorgesehen. Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.The constriction or constrictions are expedient in a horizontal one Part of the expansion pipe provided. An embodiment is in the drawing shown.
F i g. 1 zeigt schematisch ein Expansionsgefäß mit der Vorrichtung gemäß der Erfindung; F i g. 2 zeigt eine Einzelheit im Expansionsrohr.F i g. 1 shows schematically an expansion vessel with the device according to the invention; F i g. Figure 2 shows a detail in the expansion tube.
F i g. 1 zeigt ein Expansionsgefäß 1 mit Expansionsrohr 2, Überlauf 7 und Entlüftungsrohr B. Das im Wasser 3 des Gefäßes befindliche Ende des Expansionsrohres 2 erstreckt sich in Form von einem oder mehreren, am freien Ende offenen Zweigrohren 4, so daß Wasser durch die Zweigrohre und weiter durch das Rohr 2 zurück zur nicht gezeigten Anlage strömen kann. In jedem Zweigrohr 4 des Rohres 2 ist, wie deutlicher in F i g. 2 dargestellt ist, eine Anzahl von Einschnürungen 5 vorgesehen, und auf der Ablaßseite jeder Einschnürung ist, in der Zurückströmungsrichtung gesehen, in der Rohrwand ein Loch 6 angeordnet.F i g. 1 shows an expansion vessel 1 with an expansion pipe 2, overflow 7 and vent pipe B. The end of the expansion pipe located in the water 3 of the vessel 2 extends in the form of one or more branch pipes open at the free end 4 so that water through the branch pipes and further through the pipe 2 back to the no shown system can flow. In each branch pipe 4 of the pipe 2 it is clearer how in Fig. 2 is shown, a number of constrictions 5 are provided, and on the outlet side of each constriction, viewed in the backflow direction, is in a hole 6 is arranged in the pipe wall.
Wenn das Wasser durch das Zweigrohr 4 strömt, wird es an der Einschnürung 5 eine Geschwindigkeitszunahme erfahren, worauf die Geschwindigkeit hinter der Einschnürung wieder verringert wird. Durch diese Änderung der Geschwindigkeit wird dem Wasser beigemischte Luft gegen die Oberfläche des strömenden Wassers gepreßt und aus dem Wasser entweichen. Die entwichene Luft tritt dann durch das Loch 6 heraus. Durch die erfindungsgemäße Vorrichtung wird somit Luft mit dem Wasser aus dem Expansionsgefäß nicht zur Anlage mitgeführt und Korrosion und andere Nachteile werden dadurch stark verringert.When the water flows through the branch pipe 4, it becomes at the constriction 5 experience an increase in speed, whereupon the speed behind the constriction is reduced again. This change in speed changes the water mixed air is pressed against the surface of the flowing water and out of the Water will escape. The air that has escaped then exits through hole 6. By the device according to the invention thus becomes air with the water from the expansion vessel not carried to the system and corrosion and other disadvantages become severe as a result decreased.
