Die Neuerung betrifft ein Doppelrüekschlagventil zum Einbau in die Umlauf- bzw. Zirkulationsleitung von ¥armwass«rb»r»iiungsanlag«Ä, dessen Ventilkegel als Doppelkegel ausgebildet und so angeordnet ist, daß jeweils bei offener Zirkulation, d. h. keine Warmwasserentnahme, die untere Ventikkegelseite die Kaltwasserzuleitung absperrt. Bei Entnahme von Warmwasser hingegen hebt sieh der Tentilkegel durch den Zufluß von Kaltwasser zum Boiler vom unteren Sitz ab und schließt mit seinem oberen Teil die Umlauf- bzw. Zirkulationsleitung ab. Das Kaltwasser kann also nur in den Boiler und nicht in die Zirkulation fließen.The innovation concerns a double check valve for installation in the circulation or circulation line von ¥ armwass «rb» r »iiungsanlag« Ä, its valve cone is designed as a double cone and is arranged so that in each case with open circulation, d. H. no Hot water withdrawal, the lower side of the valve cone shuts off the cold water supply line. When removing Warm water, on the other hand, can be seen through the valve cone the flow of cold water to the boiler from the lower seat and closes with its upper part the Circulation or circulation line. The cold water can only go into the boiler and do not flow into the circulation.
Bisher war durch den Einbau eines normalen Rückschlagventiles herkömmlicher Bauart die Situation so, daß zwar das Zurücktreten des sich ausdehnenden Warmwassers in die Kaltwasserleitung verhindert wurde, daß aber bei Entnahme von Warmwasser das zufließende Kaltwasser statt in den Boiler in die Zirkulationsleitung fließt und zunächst nach Öffnen des Zapfhahnes aus der Leitung wieder ablaufen muß.So far, the situation was through the installation of a normal check valve of conventional design so that although the retreat of the expanding hot water prevented in the cold water pipe was that, however, when hot water is withdrawn, the cold water flowing into the water instead of into the boiler Circulation line flows and must first run out of the line again after opening the tap.
Die Vorteile, die der Einbau eines Doppelrückschlagventiles in die Warmwasserbereitungsanlage bietet, liegen klar auf der HandiThe advantages of installing a double check valve into the water heating system are obvious
1. Erhebliche Kostenersparnis an Brennstoff und Wasserverbrauch1. Considerable cost savings in fuel and water consumption
2. Jederzeit heißes Wasser bereit zu entnehmen, ohne daß zunächst das Kaltwasser aus der Leitung ablaufen muß, wie das bei Systemen ohne Doppelrückschlagventile der Fall ist.2. Hot water ready to be drawn off at any time, without the cold water from the pipe first must run, as is the case with systems without double check valves.
3. Kein kaltes Wasser kann in das Warmwasserleitungsnetz zufließen.3. No cold water can enter the hot water pipe network flow in.
4· Kein heißes Wasser kann in das Kaltwasserleitungsnetz eintreten4 · No hot water can enter the cold water mains enter
5» Völlig geräuschloses Arbeiten, da der elastisch dichtende Doppelkegel alle etwa auftretenden Rohrschläge und Leitungsgeräusche auffängt.5 »Completely noiseless operation, as it is elastic sealing double cone absorbs any pipe impacts and pipe noises that may occur.
