Description
Flüssigkeitserhitzer mit durch den Wasserdruck beeinflußtem Gasventil. Die Erfindung bezieht sich auf Flüssigkeitserhitzer mit durch den Wasserdruck beeinflußtem Gasventil, welches in bekannter Weise durch Erzeugung eines Druckunterschiedes betätigt wird. Das Neue an diesem Ventil ist, daß im Wasserlauf keine Stopfbüchse und kein mechanisch bewegter Teil mit dem Wasser in Berührung kommt; somit ist die möglichste Betriebssicherheit gewährleistet. Bei Ventilen, bei welchen mechanisch bewegte Teile im Wasser liegen, kann eine Hemmung derselben durch Oxydation, bei kalk- und eisenhaltigem Wasser durch Bildung eines Ansatzes sowie auch durch mitgeführte Schmutzteilchen eintreten und der Betrieb dadurch behindert werden.Liquid heater with gas valve influenced by the water pressure. The invention relates to liquid heaters with influenced by the water pressure Gas valve which is operated in a known manner by generating a pressure difference will. The new thing about this valve is that there is no stuffing box in the watercourse and no mechanically moving part comes into contact with water; thus is the most possible Operational safety guaranteed. For valves with which mechanically moving parts lying in water can be inhibited by oxidation, in the case of calcium and iron Water due to the formation of a deposit and also due to dirt particles carried along occur and the operation will be hindered as a result.
Nach der Erfindung liegt das Gasventil zwischen den ungleich großen Membranen zweier durch ein Umleitungsrohr verbundener Wasserdruckkammern, die in an sich bekannter Weise durch eine ,Stauschraube beim Öffnen einer Zapfstelle Druckunterschied und beim Schließen der Zapfstelle Druckausgleich erhalten.According to the invention, the gas valve is between the unequal sizes Diaphragms of two water pressure chambers connected by a diversion pipe, which are in In a manner known per se, a pressure difference when opening a tapping point is caused by a locking screw and get pressure equalization when closing the tap.
Abb. i zeigt die Erfindung im wagerechten Schnitt, Abb. a eine Ansicht von vorn.Fig. I shows the invention in a horizontal section, Fig. A is a view from the beginning.
Das Wasser tritt bei a in die Druckkammer b ein, fließt durch das Umgangsrohr c in die Druckkammer a und durch den Ausgang c nach dem Flüssigkeitserhitzer. Die einstellbare Stauschraube f behindert den Durchfluß und erzeugt in der Druckkammer b Überdruck, dagegen in der Druckkammer d Unterdruck, sobald eine Zapfstelle der Warmwasserleitung geöffnet wird. Die hinter einer Membran liegende kleinere Druckscheibe g überwindet durch den auf ihr lastenden stärkeren Druck die ebenfalls hinter einer Membran liegende größere Druckscheibe h mit schwächerer Druckbelastung; beide Druckscheiben g, h sitzen je an einem Ende der Spindel i, auf welcher der Gasventilkegel k angeordnet ist. Das Gäsveritil wird somit geöffnet. Der Hub der Spindel i kann durch die Schraubenmutter l begrenzt werden, wodurch mehr oder weniger Gas durchgelassen wird. Das Gas tritt bei m ein und bei n nach dem Brenner aus; der Gashahn o dient in bekannter Weise zum Absperren des Gases und ist durch ebenfalls bekannte Hebelverbindung mit dem Zündhahn p gesperrt. Beim Schließen der Zapfstelle tritt in den Druckkammern b und d Druckausgleich ein, und die kleinere Druckscheibe g wird von der größeren Druckscheibe h überwunden und das Gasventil durch Verschiebung der ,Spindel i geschlossen. Die Druckfeder q hält das Gasventil bei etwa abgestellter Wasserleitung geschlossen; die Gasabdichtung der Spindel i erfolgt durch die Stopfbüchsen r, r1, welche selbsttätig durch Federdruck nachdichten und den Gasaustritt nach den neutralen Kammern s, s1 verhüten. Die Druckscheiben g, h können auch gleich groß sein, wenn der Unterschied durch eine stärkere Druckfeder q ausgeglichen wird.The water enters the pressure chamber b at a, flows through the bypass pipe c into the pressure chamber a and through the outlet c after the liquid heater. The adjustable screw f obstructs the flow and generates overpressure in the pressure chamber b, but underpressure in the pressure chamber d as soon as a tap on the hot water pipe is opened. The smaller pressure disk g, located behind a membrane, overcomes the larger pressure disk h, also located behind a membrane, with a lower pressure load due to the higher pressure on it; both pressure disks g, h each sit at one end of the spindle i on which the gas valve cone k is arranged. The Gäsveritil is thus opened. The stroke of the spindle i can be limited by the screw nut l, whereby more or less gas is let through. The gas enters at m and exits the burner at n; the gas tap o is used in a known manner to shut off the gas and is locked by a lever connection with the ignition tap p, which is also known. When the tap is closed, pressure equalization occurs in the pressure chambers b and d , and the smaller pressure disc g is overcome by the larger pressure disc h and the gas valve is closed by moving the spindle i. The compression spring q keeps the gas valve closed when the water pipe is shut off; the gas sealing of the spindle i is carried out by the stuffing boxes r, r1, which reseal automatically by spring pressure and prevent the gas from escaping to the neutral chambers s, s1. The pressure disks g, h can also be of the same size if the difference is compensated for by a stronger compression spring q.
