Description
Es sind gasbeheizte Flüssigkeitserhitzer bekannt, bei denen gleichzeitig mit dem Gasventil die Sperrklappe in der Abgasleitung vom Wasserzufiuß gesteuert wird. Beim Versagen der Steuervorrichtung für die Sperrklappe können die gesundheitsschädlichen Abgase dann nicht entweichen, sondern treten in den Aufstellungsraum des Erhitzers ein.There are gas-heated liquid heaters known in which at the same time as the gas valve the shut-off valve in the exhaust pipe is controlled by the water supply. At the Failure of the control device for the locking flap can be harmful to health Exhaust gases then do not escape, but enter the room where the heater is installed a.
Durch die Erfindung sollen derartige Möglichkeiten für Unglücksfälle dadurch ausgeschaltet werden, daß der Wasserzustrom zum Erhitzer und damit auch die Gaszufuhr nur freigegeben werden, wenn die Sperrklappe in der Abgasleitung offen ist. Die Erfindung besteht darin, daß ein gasbeheizter Flüssigkeitserhitzer mit selbsttätig vom Wasserdruck gesteuertem Gasventil und ebenfalls selbsttätig vom Wasserdruck mittels Membran oder KoI-The invention is intended to eliminate such possibilities for accidents be that the water flow to the heater and thus the gas supply are only released when the shut-off valve is in the exhaust pipe is open. The invention consists in that a gas-heated liquid heater with gas valve automatically controlled by the water pressure and also automatically controlled by the water pressure by means of a membrane or
ao ben gesteuerter Absperrklappe in der Abgasleitung mit einem mit der Absperrklappe zwangsläufig beweglichen, den Flüssigkeitsdurchlaß beherrschenden Sperrkörper versehen ist.ao ben controlled butterfly valve in the exhaust pipe with one with the butterfly valve inevitably provided movable, the liquid passage dominating blocking body is.
Auf der Zeichnung ist eine Ausführung der Erfindung dargestellt. Die Fig. 1 und 2 zeigen die Anordnung der Einrichtung in den Grundzügen an einem selbsttätigen Flüssigkeitserhitzer. In den Fig. 3 und 4 ist die Sicherungsvorrichtung im Schnitt bei offenem und bei geschlossenem Flüssigkeitsdurchlaß dargestellt. Für diese Ausführungsform ist eine Membran als Steuerorgan gewählt. Es kann jedoch ebensogut ein KoI-ben o. dgl. Verwendung finden. Die Bezugszeichen haben folgende Bedeutung: α ist die in die Abgasleitung eingesetzte Sperrklappe, c die Steuereinrichtung für diese, b die Abgasleitung, d der Flüssigkeitserhitzer, e der Kaltwasserzufiuß, / die Warmwasserleitung, g eine vor dem Flüssigkeitserhitzer von der Kaltwasserzuflußleitung e abzweigende Verbindungsleitung zur Kammer der Membran. An embodiment of the invention is shown in the drawing. 1 and 2 show the arrangement of the device in the basics on an automatic liquid heater. 3 and 4, the securing device is shown in section with the liquid passage open and with the liquid passage closed. For this embodiment, a membrane is chosen as the control element. However, a KoI-ben or the like can just as well be used. The reference symbols have the following meanings: α is the shut-off valve inserted into the exhaust pipe, c the control device for this, b the exhaust pipe, d the liquid heater, e the cold water inflow / the hot water pipe, g a connecting line branching off from the cold water inflow pipe e to the chamber before the liquid heater the membrane.
Die Arbeitsweise der Einrichtung ist folgende:The operation of the facility is as follows:
Wird an irgendeiner Stelle der Warmwasserlej|un£y^eia^pfhajhinje^,net, so tritt dürchdäs Auslaufen des Wassers ein Druckabfall in der Leitung e und im Flüssigkeitserhitzer g ein. Die Membran h der Steuereinrichtung wölbt sich unter dem Einfluß des in der Leitung g herrschenden vollen Wasserleitungsdruckes, öffnet die Jyperrklappe a in 4er Abgasleitung b und schiebt hierbei gleichzeitig mittels der Spindel i das Sperrorgan k von seinem Sitze/. Das Wasser kann dann ungehindert durch den Erhitzer nach den Zapfstellen strömen. Außerdem läßt die Wassermangelsicherung in bekannter Weise das Gas zum Brenner strömen. Der beim Schließen des Zapfhahnes eintretende Druckausgleich läßt die Membran unter Einfluß der Feder m wieder in die Ruhestellung zurückkehren. Die Sperrklappe α schließt sich, und das Sperrorgan k legt sich vor die öffnung Z. Tritt nun der Fall ein, daß die Steuervorrichtung für die Sperrklappe in der Abgasleitung versagt, z. B. infolge schadhafter Membran oder Hängenbleiben der Spindel i, so bleibt das Sperrorgan k vor der öffnung Z liegen, so daß kein Wasser gezapft werden kann. Infolgedessen verhindert die Wassermangelsicherung auch ein öffnen des Gasventils, so daß Unfälle infolge Nichtöffnens der Sperrklappe durch in den Aufstellungsraum austretende Abgase vermieden werden. If at any point the Warmwasserlej | un £ y ^ eia ^ ^ pfhajhinje, net, so dürchdäs water leakage occurs a pressure drop in the line e and g in liquid heater one. The diaphragm h of the control device arches under the influence of the full water line pressure prevailing in the line g , opens the valve a in the 4-way exhaust line b and at the same time pushes the locking element k from its seat by means of the spindle i. The water can then flow unhindered through the heater to the taps. In addition, the low water protection allows the gas to flow to the burner in a known manner. The pressure equalization that occurs when the tap is closed causes the membrane to return to the rest position under the influence of the spring m. The locking flap α closes, and the locking member k lies in front of the opening Z. If the case now occurs that the control device for the locking flap in the exhaust pipe fails, e.g. B. as a result of a damaged membrane or sticking of the spindle i, the locking member k remains in front of the opening Z so that no water can be tapped. As a result, the water shortage safety device also prevents the gas valve from opening, so that accidents due to non-opening of the shut-off flap caused by exhaust gases escaping into the installation room are avoided.
