Description

Gasventil Die Erfindung bezieht sich auf ein Gasventil, insbesondere für Gas-Wasserheizer, welches durch ein auf einen dynamischenDruckunterschied ansprechendes Hubglied (Membran, Kolben od. dgl.) betätigt wird und im Gasweg dem Hauptbrenner vorgeschaltet ist.Gas valve The invention relates to a gas valve, in particular for gas water heaters, which by means of a Lifting member (diaphragm, piston or the like) is actuated and the main burner in the gas path is upstream.

Das Gasventil hat nicht nur die Aufgabe, beim Öffnen den Gasweg freizugeben, sondern auch während des öffnens die durchströmende, Gasmenge so zu dosieren, daß zunächst nur eine kleine, sogenannte Durchzündgasmenge und erst nach Erreichen eines bestimmten Hubes die volle Gasmenge zum Hauptbrenner strömen kann.The gas valve not only has the task of releasing the gas path when it is opened, but also to dose the amount of gas flowing through during opening so that initially only a small amount of so-called ignition gas and only after one has been reached the full amount of gas can flow to the main burner at a certain stroke.

Bisher hat man das dadurch erreicht, daß der Gasventilteller mit einem Schleppkolben versehen wurde, dessen Außendurchmesser mit dem Innendurchmesser des Gasventilsitzes einen Ringspalt bildete, dessen Größe so bemessen war, daß beim öffnen die richtige Durchzündgasmenge zum Hauptbrenner gelangte.So far, this has been achieved by providing the gas valve disk with a drag piston, the outer diameter of which formed an annular gap with the inner diameter of the gas valve seat, the size of which was such that the correct amount of ignition gas reached the main burner when it was opened.

Dabei hat ein bestimmter Ringspalt nur für einen gewissen Bereich von Wobbezahlen Gültigkeit. Je höher die Wobbezahl, desto enger muß der Ringspalt sein. Und je enger der Ringspalt, desto höher sind die Anforderungen an die Genauigkeit der Durchmesser.A certain annular gap is only valid for a certain range of Wobbe numbers. The higher the Wobbe number, the narrower the annular gap must be. And the narrower the annular gap, the higher the demands on the accuracy of the diameter.

Bei Gasen mit sehr hohen Wobbezahlen, z. B. Butan, ist die Bemessung der Durchzündgasmenge mittels Ringspalt durch die auftretenden Fertigungstoleranzen der Durchmesser größeren Schwankungen unterworfen. Außerdem besteht bei sehr engen Ringspalten die Gefahr der Verschmutzung.For gases with very high Wobbe numbers, e.g. B. butane, is the rating the amount of ignition gas by means of the annular gap due to the manufacturing tolerances that occur the diameter is subject to greater fluctuations. There is also very tight Annular gaps the risk of contamination.

Der Erfindung lag die Aufgabe zugrunde, ein Gasventil zu schaffen, welches diese Nachteile vermeidet. Dieses wurde dadurch erreicht, daß der Ringspalt zwischen Ventilsitzbohrung und Ventilschleppkolben durch eine Dichtung, die am Schleppkolben befestigt ist, für den Gasdurchgang versperrt wird und oberhalb der Dichtung im Schleppkolben eine für die Durchzündgasmenge notwendige Öffnung vorhanden ist.The invention was based on the object of creating a gas valve, which avoids these disadvantages. This was achieved in that the annular gap between the valve seat bore and the valve drag piston through a seal on the drag piston is attached, is blocked for the gas passage and above the seal in the Towing piston there is an opening necessary for the amount of ignition gas.

Durch dieseAnordnung ist dieDurchzündgasmenge von den Abmessungen des Ringspaltes unabhängig und durch die genau herstellbare, Öffnung eindeutig festgelegt, wenn der Ringspaltquerschnitt mit Sicherheit größer ist als diese öffnung.With this arrangement, the amount of ignition gas is of the dimensions of the annular gap and clearly defined by the precisely manufacturable opening, if the annular gap cross-section is definitely larger than this opening.

In der weiteren Ausbildung der Erfindung ist die Ventilsitzbohrung in Sitznähe erweitert, um ein besseres Zentrieren der Dichtung zu ermöglichen. Die Ringspaltverbreiterungwährend desHubes wird durch die Elastizität der Dichtung kompensiert. Um eine rationelle Fertigung des Ventiltellers zu erreichen, ist es zweckmäßig, das ganze Teil aus elastischem Werkstoff herzustellen, so daß keine losen Dichtungen erforderlich sind.In the further embodiment of the invention is the valve seat bore extended near the seat to allow better centering of the seal. the The widening of the annular gap during the stroke is compensated for by the elasticity of the seal. In order to achieve efficient production of the valve disk, it is useful to make the whole part of elastic material, so that no loose seals required are.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, und zwar zeigt die linke Hälfte die Stellung »Gasventil offen« und die rechte »Gasventil geschlossen«. Im folgenden die Beschreibung: Im Ventilgehäuse 1, das einen Gasventilsitz 2 bildet, ist der Ventiltellex 3 eines Gasventils angeordnet, dessen Ventilstift 4 von einem nicht dargestellten Differenzdruckschalter gegen die Kraft der Feder 5 angehoben wird. Der Ventilteller 3 hat eine Flachdichtung 6 und eine Öffnung 7 am Umfang des Schleppkolbens 8. Am unteren Ende des Schleppkolbens 8 befindet sich eine Runddichtung 9. Die Öffnung 7 steht mit dem Gaseingang 10 in Verbindung.An embodiment of the invention is shown in the drawing, namely the left half shows the "gas valve open" position and the right "gas valve closed". The description follows: In the valve housing 1, which forms a gas valve seat 2, the valve stem 3 of a gas valve is arranged, the valve pin 4 of which is raised by a differential pressure switch (not shown) against the force of the spring 5 . The valve plate 3 has a gasket 6 and an opening 7 8 at the periphery of the drag piston at the lower end of the drag piston 8 is an O-ring 9. The opening 7 is in communication with the gas input 10th

Wird der Ventilteller 3 von dem Differenzdruckschalter angehoben, so strömt das Gas vom Eingang 10 zunächst nur durch die öffnung 7 und den Ringspalt 11 zwischen dem Sitz 2 und der Flachdichtung 6 dem nicht dargestellten Hauptbrenner in begrenzter Menge zu. Erst wenn der Hub des Ventiltellers 3 so groß ist, daß der Schleppkolben 8 mit der Runddichtung 9 die Ventilsitzbohrung 12 verläßt, wird der volle Querschnitt 13 freigegeben.If the valve disk 3 is lifted by the differential pressure switch, the gas from the inlet 10 initially only flows through the opening 7 and the annular gap 11 between the seat 2 and the flat seal 6 to the main burner (not shown) in limited quantities. Only when the stroke of the valve disk 3 is so great that the drag piston 8 with the round seal 9 leaves the valve seat bore 12, the full cross section 13 is released.
