Description

Die Erfindung betrifft ein geschlossenes Ausdehnungsgefäß mit zwei ineinanderliegenden Behältern.The invention relates to a closed expansion vessel with two containers lying one inside the other.

Ein bekanntes Ausdehnungsgefäß (AT-PS 3200215) besteht aus einem druckfesten Behälter, welcher im mittleren Bereich durch eine gelochte oder geschlitzte Zwischenwand in zwei Kammern geteilt ist. Eine Kammer enthält ein zusammendrückbares Medium z.B. Druckgas, die andere enthält eine Blase die zur Aufnahme von Warmwasser dient.A known expansion vessel (AT-PS 32 0 0215) consists of a pressure-resistant container, which is divided into two chambers in the central area by a perforated or slotted partition. One chamber contains a compressible medium such as compressed gas, the other contains a bubble that is used to hold hot water.

Der Erfindung liegt die Aufgabe zugrunde, ein Ausdehnungsgefäß zu schaffen, daß das im flüssigen Energieträger vorhandene Gasgemisch in einem Gasgemischraum sammelt, wo es zur Aufnahme der Volumsänderungen des flüssigen Energieträgers dient. Die Aufgabe wird dadurch gelöst, daß das Ausdehnungsgefäß einen inneren Behälter und einen, durch einen flüssigen Energieträger getrennten, äußeren Behälter aufweist, wobei der flüssige Energieträger in den inneren Behälter durch einen Einlaßanschluß unterhalb eines Geflechtes einströmt, anschließend durch ein Geflecht ein im Energieträger enthaltenes Gasgemisch in einen, im oberen Teil des inneren Behälters angeordneten Gasgemischraum abgibt, Schwebstoffe zu einem Entschlammventil absinken lässt und der gereinigte und entgaste Energieträger durch einen am oberen Ende des äußeren Behälters angeordneten Auslaßanschluß ausfließt.The invention has for its object to provide an expansion vessel that the gas mixture present in the liquid energy carrier collects in a gas mixture space, where it serves to absorb the volume changes of the liquid energy carrier. The object is achieved in that the expansion vessel has an inner container and an outer container separated by a liquid energy carrier, the liquid energy carrier flowing into the inner container through an inlet connection below a braid, then through a braid a gas mixture contained in the energy carrier releases into a gas mixture space arranged in the upper part of the inner container, lets suspended matter sink to a sludge valve and the cleaned and degassed energy carrier flows out through an outlet connection arranged at the upper end of the outer container.

Eine zweckmäßige Ausführungsform der Erfindung besteht darin, daß aus dem inneren Behälter eine Überströmleitung, die mit einer Entlüftungsvorrichtung und einem Absperrorgan versehen ist, geführt ist, die verhindert, daß das Gasgemisch aus dem Gasgemischraum durch den unteren Teil des inneren Behälters in den äußeren Behälter zur Auslaßöffnung des Energieträgers gelangt.An advantageous embodiment of the invention is that an overflow line is provided from the inner container, which is provided with a venting device and a shut-off device, which prevents the gas mixture from the gas mixture space through the lower part of the inner container into the outer container Exhaust opening of the energy source arrives.

Eine abgewandelte Ausführungsform der Erfindung besteht darin, daß im inneren Bekälter eine schwimmende Trennscheibe angeordnet ist, die an der wand des inneren Behälters gleitet, um eine bessere Trennung des Gasgemisches und des flüssigen Energieträgers zu erreichen.A modified embodiment of the invention consists in that a floating cutting disc is arranged in the inner cooler, which slides on the wall of the inner container in order to achieve a better separation of the gas mixture and the liquid energy carrier.

In der Zeichnung ist eine beispielsweise Ausführungsform dargestellt. Fig. 1 zeigt einen Längsschnitt entlang der Linie A-B in Fig. 2. Fig. 2 zeigt eine Draufsicht mit abgenommenem oberen Boden.An example of an embodiment is shown in the drawing. Fig. 1 shows a longitudinal section along the line A-B in Fig. 2. Fig. 2 shows a plan view with the upper bottom removed.

In den äußeren Behälter 1 des Ausdehnungsgefäßes mit dem Auslaßanschluß 2 und dem Entschlammventil 3 (z.B.Kugelhahn, Schrägsitzventil, Absperrhahn, etc.) ist ein innerer Behälter 4 eingebaut. Der innere Behälter 4 weist einen unteren Teil 5 auf, in den der Einlaßanschluß 6 mündet. Der innere Behälter4 ist, auf der Seite die dem Entschlammventil 3 näher ist, offen. In den unteren Teil 5 des inneren Behälter 4 ist, oberhalb des Einlaßanschluß 6, ein Geflecht 7 eingebaut, daß die Abscheidung des Gasgemisches aus dem, durch den Einlaßanschluß 6, einströmenden flüssigen Energieträger bewirkt. Das ausgeschiedene Gasgemisch steigt in den im inneren Behälter 4 angeordneten Gasgemischraum 8 auf. Durch das Komprimieren oder die Ausdehnung des Gasgemisches werden die Volumsänderungen des Energieträgers ausgeglichen. Falls die Gasgemischmenge im Gasgemischraum 8 zu groß wird, kann die Überschußmenge durch eine Überströmleitung 9 entweichen. Die Überströmleitung 9 ist mit einer Entlüftungsvorrichtung 10 (z.B. automatischer Lufttopf, etco) versehen, die verhindert, daß der flüssige Energieträger ausströmt, ebenso wird an die Überströmleitung 9 ein Absperrorgan 11 (z.B. Kugelhahn, etc.) angeordnet, durch das ein Gasgemisch in den Gasgemischraum 8 preßbar ist, um die Dichtheit des inneren Behälters 4 oberhalb des Einlaßanschlusses 6 prüfen zu können. Um die Aufnahme des Gasgemisches in den flüssigen Energieträger zu verhindern, ist der Stand des flüssigen Energieträgers höher als das Geflecht 7. Ja nach Größe des inneren Behälters 4 kann zusätzlich eine schwimmende Trennscheibe 12 im inneren Behälter 4 eingebaut werden.An inner container 4 is installed in the outer container 1 of the expansion vessel with the outlet connection 2 and the sludge valve 3 (e.g. ball valve, angle seat valve, shut-off valve, etc.). The inner container 4 has a lower part 5, into which the inlet port 6 opens. The inner container 4 is open on the side closer to the sludge valve 3. In the lower part 5 of the inner container 4, a braid 7 is installed above the inlet connection 6, which causes the separation of the gas mixture from the liquid energy source flowing in through the inlet connection 6. The separated gas mixture rises into the gas mixture space 8 arranged in the inner container 4. The volume changes in the energy source are compensated for by compressing or expanding the gas mixture. If the amount of gas mixture in the gas mixture space 8 becomes too large, the excess amount can escape through an overflow line 9. The overflow line 9 is provided with a venting device 10 (e.g. automatic air pot, etc.) which prevents the liquid energy source from flowing out, and a shut-off device 11 (e.g. ball valve, etc.) is arranged on the overflow line 9, through which a gas mixture flows into the Gas mixture space 8 can be pressed in order to be able to test the tightness of the inner container 4 above the inlet connection 6. In order to prevent the gas mixture from being absorbed into the liquid energy carrier, the level of the liquid energy carrier is higher than the braid 7. Depending on the size of the inner container 4, additional Lich a floating cutting disc 12 can be installed in the inner container 4.
