Description

Die Erfindung betrifft einen Zapfhahn für Warmwasserentnahme.The invention relates to a tap for drawing off hot water.

Aufgabe der Erfindung ist es, einen Zapfhahn nach Patent 857 563 zu schaffen, dessen Lebensdauer nahezu unbegrenzt ist. Diese Aufgabe wird im wesentlichen dadurch gelöst, daß. die für Stromzuführung und Stromableitung getrennten, in einen Heizbehälter oder in Heizkammern isoliert angeordneten Elektroden aus Kohle bestehen. Die Anwendung von Kohleelektroden verhindert die bei Metallelektroden übliche Zersetztjng der Elektroden mit der damit verbundenen Leistungsverminderung und schließlich völligem Ausfall der Wassererwärmung. Ein mit Kohleelektroden ausgerüsteter Zapfhahn mit Elektrodenheizung ist nahezu keinem Verschleiß und keiner Zersetzung durch die elektrolytischen Wirkungen des Wassers, ausgesetzt, und seine Haltbarkeit ist fast unbegrenzt.The object of the invention is to provide a tap according to patent 857 563 create whose lifespan is almost unlimited. This task is essentially solved in that. the separate ones for power supply and power dissipation into one Heating containers or electrodes arranged insulated in heating chambers are made of carbon. The use of carbon electrodes prevents the decomposition that is common with metal electrodes of the electrodes with the associated reduction in performance and ultimately complete Failure of water heating. A tap equipped with carbon electrodes with Electrode heating is almost no wear and tear and no decomposition due to the electrolytic Effects of water, exposed, and its shelf life is almost unlimited.

In der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt.The drawing shows two exemplary embodiments of the subject matter of the invention shown.

Abb. i zeigt einen Zapfhahn im Längsmittelschnitt nach Linie A-B der Abb. 2, Abb. 2 einen Schnitt nach Linie C-D der Abb. i, Abb.3 einen Längsmittelschnitt einer anderen Ausführungsform.Fig. I shows a tap in longitudinal center section along line A-B of Fig. 2, Fig. 2 a section along line C-D of Fig. I, Fig. 3 a longitudinal center section another embodiment.

Der Zapfhahn besteht aus einem Gehäuse i mit einem normalen Rohranschlußgewinde, einem normalen Zapfhahnoberteil2, Plus- oder Phasenelektroden 3, Minus- oder Nullelektroden 4, Anschlußgewindestiften 5 mit Muttern 6, einem heißwasserbeständigen Isolierring 7, einem Elektrodenhalter 8, einer Verschlußkappe g mit einer Kabeldurchführung io. Das, Gehäuse i weist einen Heizbehälter ja auf, in dem die Elektroden 3 und 4 mittels des Isolierringes 7 und des Elektrodenhalters 8 vom Gehäuse i isoliert angeordnet sind. Das Wasser strömt nach Öffnen des Zapfhahnventils 2a durch Drehen der Handhabe 2b der Ventilspindel in die Ventilkammer ib, von dort durch die Öffnung ic in den Heizbehälter ja. Dort fließt es zwischen den Elektroden 3 und 4 hindurch und wird bei Stromdurchgang erwärmt. Das erwärmte Wasser fließt dann durch die beiden Ausflußkanä@e id um die Ventilkammer ib herum ungehindert zum Ausfluß it. Ein versehentlich unterlassenes Abschalten des Stromes hat keinerlei Nachteile bei abgesperrtem Wasser, weil der vorhandene Wasserrest verdampft, der Dampf ungehindert ins Freie ausströmen kann und der Stromzufluß unterbrochen ist.The tap consists of a housing i with a normal pipe connection thread, a normal tap top 2, plus or phase electrodes 3, minus or zero electrodes 4, threaded connection pins 5 with nuts 6, a hot water resistant insulating ring 7, an electrode holder 8, a closure cap g with a cable feed-through ok The, housing i has a heating container in which the electrodes 3 and 4 isolated from the housing i by means of the insulating ring 7 and the electrode holder 8 are arranged. The water flows after opening the tap valve 2a by turning it the handle 2b of the valve spindle into the valve chamber ib, from there through the opening ic in the heating container yes. There it flows through between electrodes 3 and 4 and is heated when the current passes through it. The heated water then flows through the two Ausflusskanä @ e id around the valve chamber ib around unhindered to the outflow it. One accidentally Failure to turn off the electricity has no disadvantages when the water is shut off, because the remaining water evaporates, the steam can flow unhindered into the open air and the power supply is interrupted.

In Abb. 3 fließt das Wasser nacheinander durch drei Heizkammern i i, von denen im dargestellten Beispiel jede mit einer anderenDrehstromphase verbunden sein kann, wodurch sich das durchfließende Wasser außerordentlich rasch und intensiv erwärmt. Die in diesen beispielsweise beschriebenen Geräten eingebauten Elektroden bestehen hier erfindungsgemäß aus Kohle.In Fig. 3 the water flows one after the other through three heating chambers i i, each of which is connected to a different three-phase phase in the example shown can be, whereby the flowing water is extraordinarily fast and intense warmed up. The electrodes built into these devices described for example consist of coal according to the invention.
