Definitions
- the invention relates to a hydraulic regulated gas valve for a fuel gas heated continuous water heater.
- Such gas fittings are characterized in that they adjust the amount of fuel gas that reaches a burner depending on the amount of water to be heated and a knob.
- an amplification factor fuel gas volume flow to water volume flow
- Such fittings are made, for example EP 1 353 126 A and from DE 4 316 779 A known.
- these gas fittings must have at least two sealing valves which have different control signals.
- the ionization current in a flame or a thermoelectric voltage caused by the flame is used as a control signal. If a flame is present on the burner surface, an ionization current can be detected in the area of the flame. With this ionization current, a valve, the safety valve, can be opened by means of a coil.
- the other sealing valve is usually the water shortage valve. In this valve, a stroke equivalent to the water volume flow is generated in a water switch. By means of this lifting movement, the water shortage valve can be opened and thus a fuel gas equivalent to the water volume flow can flow through the gas fitting.
- gas valves often have a valve with which an amplification factor between the fuel gas volume flow and the water volume flow can be set. This adjustment is usually done manually by the operator, who often uses a rotary knob and diverter to continuously open or close a linear valve. As a result, the outlet temperature of the continuous water heater is changed.
- Gas fittings for fuel gas heated continuous water heaters are usually relatively complex, since the various functions are achieved by a mechanism with many deflections.
- the aim of the invention is to provide a gas valve for fuel gas heated continuous water heater, which is characterized by simple and reliable structure.
- the ignition gas guide and seal should be simplified.
- the fuel gas is passed to the pilot gas valve through the interior of the main gas valve. Since this is sealed from the environment, small leaks would not result in fuel gas leakage into the environment.
- the ignition gas is passed through the same guide as the mechanical actuating mechanism of the safety valve.
- existing holes and cavities are used twice.
- Another advantage of an advantageous embodiment of the invention is according to claim 5, that the gas valve at the factory setting or on site without installation of an additional throttle by an existing, from the outside - to compensate for manufacturing tolerances and to different performance variables, network pressures and gas types - adjustable valve can be adjusted.
- the elimination of an additional throttle the pressure drop of the gas valve is kept to a minimum.
- the nominal power and the partial load can be adjusted.
- only a universal power preselector valve is installed, which in the case of a gas type change at the customer no longer needs to be removed and replaced. This can save costs and the device is much more attractive for the customer due to the increased flexibility.
- the power preselector valve cone is infinitely and sensitively displaceable and thus adjustable. This is possible because a Axialschalt consultancy can move on a shaft by turning the adjusting screw via a clamp.
- the adjusting screw is located coaxially with the gas control mechanism directly behind the gas button, so that its action is self-explanatory.
- Fig. 1 to Fig. 16 the gas valve according to the invention in various operating situations and details thereof.
- FIG. 1 shows the gas valve according to the invention in the diagonal plan view with the control knob 1 at the front, the side receiving bore 43 for the water switch, the rear gas inlet 44, the also rear thermomagnet 48, the gas outlet 45 to the burner, the measuring nipple 47 for measuring the inlet pressure, the Measuring nipple 39 for measuring the burner pressure and the ignition gas outlet 26.
- the FIGS. 2a and 2b show the gas valve according to the invention from other perspectives also in diagonal plan view.
- FIG. 3 shows the gas valve according to the invention in section A - A according to FIG. 1 ,
- the gas valve is in the initial state, in which no fuel gas flows.
- the control knob 1 is in the starting position.
- the safety valve 2 with the thermomagnet 48, the Zündgasventil 3, the main gas valve 4 for power selection, which includes a buttervorinesventilteller 23, and the water shortage valve 5, not in FIG. 3 but in eg FIG. 8 can be seen, are closed.
- the gas inlet 44 which is in FIG. 3 can not be seen, fuel gas is on the left in front of the safety valve 2.
- FIG. 4 is brought by turning counterclockwise the control knob 1 counterclockwise, the gas valve in the ignition position.
- the rotational movement of the control knob 1 is transmitted to a radial contact piece 10.
- the radial contact piece 10 has a control cam 21 (see. FIG. 14 ), whereby the radial increase of the control cam 21 causes a counterclockwise rotation of the Zündgasventiltellers 11 against the spring 12 in a rotational movement.
- a Zündgasfilter 13 is slightly compressed.
- a flat gasket 14 lifts off from a Zündgasventilsitz 15.
- FIG. 5 shows that in the next operating step, the control knob 1 is pressed with the shaft 6 against the spring 16.
- the adjusting screw 8, the bracket 17 (see also Fig. 15 ), the radial switch 10, the pin 7 and a Axialschalt choir 9 are also moved.
- the pin 7 strikes the valve plate 18 of the thermomagnet 48 and lifts against the pressure of the spring 49, the gasket 19 from the valve seat 20 from.
- the fuel gas can now flow through a gap 22 centrally through the power preselector valve plate 23 into the chamber 24. From there, the fuel gas through the gap 25, the path via the Zündgasfilter 13 to Zündgasausgang 26th
- the ignition gas burner can now be ignited. After the ignition gas has been ignited at the pilot gas burner, a thermal current can be tapped from the flame after a short waiting time. This thermo-current is passed to the thermomagnet 48, whereby the thermomagnet 48 pulls the valve plate 18 to the thermomagnet 48 against the spring 49.
- the control knob 1 can now be released by the operator. As a result, slide the parts control knob 1, shaft 6, Radialschalt Science 10, adjusting screw 8, bracket 17, Axialschalt fabrics 9 and pin 7 due to the force of the spring 16 back to the starting position. The ignition gas continues to flow.
- the Axialschalthggse 27 Since sliding blocks 28 of the Axialschalthggse 27 (see. Fig. 16 ) sitting in longitudinally extending grooves in the housing 30, only axial movement of the Axialschalthggse 27 is possible.
- the Axialschalthggse 27 has a locking lug 29 (see. Fig. 16 ), which with the switching cam 31 or the notches 32 of the rotating Axialschalt Sharings 9 (see. Fig. 15 ) is in contact.
- the latching lug 29 (see. Fig. 16 ) slides along the switching cam 31 (cf. Fig.
- FIG. 6 shows the position of the power selector valve plate 23 for the lowest power level
- FIG. 7 the state in which the control knob 1 has been rotated via intermediate positions to the highest power level in the counterclockwise direction, whereby the locking lug 29 engages in the last notch 32 of the Axialschal Switzerlands 9.
- the power preselector valve plate 23 now releases the maximum flow cross section.
- the Figures 10 and 11 illustrate the adaptation of the main gas valve 4 to different manufacturing tolerances, performance variables, different network pressures and fuel gas types.
- control knob 1 To adjust the control knob 1 is rotated in a defined level and then subtracted. By the tap of water, the device is started, while the burner pressure by measuring the pressure measuring nipple 39 (see. Fig. 1 ) is continuously measured.
- the spring 16 acts in two ways (previous systems use for this purpose two springs): Once during the ignition, when the control knob 1 is pressed against the spring 16, and then upon release of the knob 1 so that the mechanism with shaft and button is reset , On the other hand, when opening and closing the power selector valve plate 23.
- the adjustment is sensitive and infinitely variable.
- the dynamic seal ( Fig. 3 ) between shaft 6 and housing is stressed axially only during the ignition process. Screwing movements do not occur.

Abstract
Description
Die Erfindung bezieht sich auf eine hydraulische geregelte Gasarmatur für einen brenngasbeheizten Durchlauf-Wasserheizer.The invention relates to a hydraulic regulated gas valve for a fuel gas heated continuous water heater.
Derartige Gasarmaturen zeichnen sich dadurch aus, dass sie in Abhängigkeit der zu erhitzenden Wassermenge und eines Stellknopfes die Brenngasmenge, die zu einem Brenner gelangt, anpassen. Mittels des Stellknopfes kann ein Verstärkungsfaktor (Brenngasvolumenstrom zu Wasservolumenstrom) eingestellt werden; das heißt, dass letztendlich die Wassertemperatur annähernd über den Knopf eingestellt wird. Derartige Armaturen sind z.B. aus
Gemäß Normanforderungen müssen diese Gasarmaturen über mindestens zwei dichtende Ventile, die unterschiedliche Steuersignale haben, verfügen. Häufig wird als ein Steuersignal der lonisationsstrom in einer Flamme oder eine von der Flamme verursachte Thermospannung verwendet. Ist eine Flamme an der Brenneroberfläche vorhanden, so kann im Bereich der Flamme ein lonisationsstrom erfasst werden. Mit diesem lonisationsstrom kann mittels einer Spule ein Ventil, das Sicherheitsventil, geöffnet werden. Bei dem anderen dichtenden Ventil handelt es sich meist um das Wassermangelventil. Bei diesem Ventil wird in einem Wasserschalter eine dem Wasservolumenstrom äquivalente Hubbewegung erzeugt. Mittels dieser Hubbewegung lässt sich das Wassermangelventil öffnen und somit kann eine dem Wasservolumenstrom äquivalente Brenngasmenge durch die Gasarmatur strömen.According to standard requirements, these gas fittings must have at least two sealing valves which have different control signals. Often, the ionization current in a flame or a thermoelectric voltage caused by the flame is used as a control signal. If a flame is present on the burner surface, an ionization current can be detected in the area of the flame. With this ionization current, a valve, the safety valve, can be opened by means of a coil. The other sealing valve is usually the water shortage valve. In this valve, a stroke equivalent to the water volume flow is generated in a water switch. By means of this lifting movement, the water shortage valve can be opened and thus a fuel gas equivalent to the water volume flow can flow through the gas fitting.
Letztendlich verfügen häufig Gasarmaturen zusätzlich über ein Ventil, mit dem ein Verstärkungsfaktor zwischen Brenngasvolumenstrom und Wasservolumenstrom eingestellt werden kann. Diese Einstellung erfolgt in der Regel manuell vom Bediener, der häufig mittels Drehknopf und Umlenkung ein Kegelventil linear kontinuierlich öffnet beziehungsweise schließt. Hierdurch wird die Auslauftemperatur des Durchlauf-Wasserheizers verändert.Finally, gas valves often have a valve with which an amplification factor between the fuel gas volume flow and the water volume flow can be set. This adjustment is usually done manually by the operator, who often uses a rotary knob and diverter to continuously open or close a linear valve. As a result, the outlet temperature of the continuous water heater is changed.
Gasarmaturen für brenngasbeheizte Durchlauf-Wasserheizer sind in der Regel relativ aufwändig, da die verschiedenen Funktionen über eine Mechanik mit vielen Umlenkungen erreicht werden.Gas fittings for fuel gas heated continuous water heaters are usually relatively complex, since the various functions are achieved by a mechanism with many deflections.
Ziel der Erfindung ist, eine Gasarmatur für brenngasbeheizte Durchlauf-Wasserheizer zu schaffen, die sich durch einfachen und zuverlässigen Aufbau auszeichnet. Die Zündgasführung und Dichtung soll vereinfacht werden.The aim of the invention is to provide a gas valve for fuel gas heated continuous water heater, which is characterized by simple and reliable structure. The ignition gas guide and seal should be simplified.
Beim Stand der Technik wird das Zündgas zwischen dem Sicherheitsventilsitz (Magnetventil) und dem Ventilsitz zur Leistungsvorwahl (Hauptgasventil) durch eine abzweigende Bohrung seitlich abgenommen und um den Schaltmechanismus herum zum Zündgasventil geführt. Da sich der Antrieb für dieses Zündgasventil außerhalb des Gasführenden Bereiches befindet, ist eine separate dynamische Dichtung am Zündgasventilstößel notwendig.In the prior art, the ignition gas between the safety valve seat (solenoid valve) and the valve seat for power preselection (main gas valve) is removed laterally by a branching bore and guided around the switching mechanism to Zündgasventil. Since the drive for this pilot gas valve is outside the gas-conducting area, a separate dynamic seal on Zündgasventilstößel is necessary.
Beim bisherigen Stand der Technik wird bei der Werkseinstellung oder bei der Anpassung vor Ort eine zusätzliche Drossel genutzt, um den maximalen Gasdurchfluss zu beschneiden und somit die Nennleistung einzustellen. Ferner werden pro Gasart und Leistungsgröße verschiedene Leistungsvorwahlventile gefertigt und montiert. Bei einer Gasartenumstellung vor Ort muss dieses Ventil durch ein anderes ausgetauscht werden, wobei in einigen Fällen sogar die komplette Gasarmatur getauscht wird.In the prior art, an additional throttle is used in the factory setting or when adjusting locally to trim the maximum gas flow and thus adjust the rated power. Furthermore, different power preselector valves are manufactured and installed per gas type and capacity. In the case of a gas changeover on site, this valve must be replaced by another, in some cases even the complete gas fitting being replaced.
Gemäß den Merkmalen des Anspruchs 1 wird das Brenngas zum Zündgasventil durch das Innere des Hauptgasventils geführt. Da dieses gegenüber der Umgebung abgedichtet ist, hätten kleine Undichtigkeiten keinen Brenngasaustritt in die Umgebung zur Folge.According to the features of
Gemäß den Merkmalen des Anspruchs 2 wird das Zündgas durch die gleiche Führung wie der mechanische Betätigungsmechanismus des Sicherheitsventils geführt. Hierdurch werden vorhandene Bohrungen und Hohlräume doppelt genutzt.According to the features of
Ein weiterer Vorteil einer vorteilhaften Ausgestaltung der Erfindung ist gemäß Anspruch 5, dass die Gasarmatur bei der Werkseinstellung oder vor Ort ohne Einbau einer zusätzlichen Drossel durch ein bereits vorhandenes, von außen - zum Ausgleich von Fertigungstoleranzen und an verschiedene Leistungsgrößen, Netzdrücke und Gasarten - einstellbares Ventil angepasst werden kann. Durch den Entfall einer zusätzlichen Drossel wird der Druckverlust der Gasarmatur auf ein Minimum beschränkt. Des Weiteren kann neben der Nennleistung auch die Teillast eingestellt werden. Beim Herstellprozess wird nur noch ein universelles Leistungsvorwahlventil eingebaut, welches im Fall einer Gasartenumstellung beim Kunden nicht mehr ausgebaut und getauscht werden muss. Damit können Kosten eingespart werden und das Gerät ist durch die erhöhte Flexibilität für den Kunden deutlich attraktiver.Another advantage of an advantageous embodiment of the invention is according to
Der Leistungsvorwahlventilkegel ist zusätzlich zur mehrstufigen Leistungsvorwahl an sich stufenlos und feinfühlig verschiebbar und somit einstellbar ist. Dies wird möglich, da sich ein Axialschaltstück auf einer Welle durch Drehen der Einstellschraube über eine Klammer verschieben lässt. Die Einstellschraube befindet sich koaxial zum Gasregelmechanismus direkt hinter dem Gasknopf, wodurch deren Wirken selbsterklärend ist.In addition to the multi-stage power preselection, the power preselector valve cone is infinitely and sensitively displaceable and thus adjustable. This is possible because a Axialschaltstück can move on a shaft by turning the adjusting screw via a clamp. The adjusting screw is located coaxially with the gas control mechanism directly behind the gas button, so that its action is self-explanatory.
Die Erfindung wird nun anhand der Zeichnungen erläutert. Hierbei zeigenThe invention will now be explained with reference to the drawings. Show here

Der Zündgasbrenner kann nun gezündet werden. Nachdem das Zündgas am Zündgasbrenner entzündet wurde, kann nach einer kurzen Wartezeit aus der Flamme ein Thermostrom abgegriffen werden. Dieser Thermostrom wird auf den Thermomagneten 48 geleitet, wodurch der Thermomagnet 48 den Ventilteller 18 zum Thermomagneten 48 gegen die Feder 49 zieht. Der Bedienknopf 1 kann nun vom Bediener losgelassen werden. Dadurch gleiten die Teile Bedienknopf 1, Welle 6, Radialschaltstück 10, Einstellschraube 8, Klammer 17, Axialschaltstück 9 und Stift 7 aufgrund der Kraft der Feder 16 zurück in die Ausgangstellung. Das Zündgas fließt weiterhin.The ignition gas burner can now be ignited. After the ignition gas has been ignited at the pilot gas burner, a thermal current can be tapped from the flame after a short waiting time. This thermo-current is passed to the

Weitere Merkmale sind, dass beim Einstellvorgang durch die Einstellschraube 8 die axiale Position des Bedienknopfs 1 sich nicht ändert. Die Stellung der Einstellschraube 8 muss aufgrund der Selbsthemmung nicht gegen selbstständiges Lösen gesichert werden. Die Feder 16 wirkt in zweifacher Hinsicht (bisherige Systeme nutzen zu diesem Zweck zwei Federn): Einmal während des Zündvorgangs, wenn der Bedienknopf 1 gegen die Feder 16 gedrückt wird, und anschließend beim Loslassen des Knopfes 1 damit der Mechanismus mit Welle und Knopf zurückgestellt wird. Zum anderen beim Öffnen und Schließen des Leistungsvorwahlventiltellers 23. Die Einstellung erfolgt feinfühlig und stufenlos. Die dynamische Dichtung (
Neben der im folgenden Text beschriebenen Gasarmatur mit Zündflamme und manueller Zündung gibt es auch noch die so genannte elektronische Gasarmatur mit elektrischer Zündung. Dabei existiert keine Zündflamme, das Hauptgas wird elektronisch direkt beim Zapfen des Wassers gezündet (Direktstarter). Die Flammenerkennung (-sicherung) erfolgt durch eine Ionisationselektrode. Der Thermoelektromagnet wird durch ein elektrisches Motorventil ersetzt welches durch Spannungsversorgung von Batterie oder Generator selbstständig öffnet und schließt. Das eingangs erwähnte ,Von außen einstellbare Leistungsvorwahlventil' wird auch bei dieser Variante mit denselben Vorzügen angewandt.In addition to the gas fitting described below with pilot flame and manual ignition, there is also the so-called electronic gas fitting with electric Ignition. There is no pilot flame, the main gas is ignited electronically directly when tapping the water (direct starter). The flame detection (assurance) is carried out by an ionization electrode. The thermo-electromagnet is replaced by an electric motor valve which automatically opens and closes by supplying power to the battery or generator. The above-mentioned, externally adjustable power selector valve 'is also used in this variant with the same benefits.
