Abstract

Hydraulically controlled gas fitting for a gas-fired continuous water heater comprises a safety valve (2), an ignition gas valve (3), and a main gas valve (4) for adjusting the amplification factor that establishes the ratio of fuel volume flow to water volume flow. The main gas valve at least consists of one output preset valve head (23) and a valve seat. The combustion gas is guided from the safety valve to the ignition gas valve through the interior of the output preset valve head.

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.Such gas fittings are characterized by the fact that they depend on the Heated amount of water and a control knob, the fuel gas amount to a Burner arrives, adjust. By means of the adjusting knob, a gain factor (Fuel gas volume flow to water volume flow) are set; it means that Finally, the water temperature is set approximately by the knob.

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 gaskets Valves that have different control signals have. Often it is called a control signal the ionization current in a flame or caused by the flame Thermoelectric voltage used. If there is a flame on the burner surface, so an ionization current can be detected in the area of the flame. With this Ionisationsstrom can be opened by means of a coil, a valve, the safety valve. The other sealing valve is usually the water shortage valve. at This valve is in a water switch equivalent to the water volume flow Hubbewegung generated. By means of this lifting movement can be the water shortage valve open and thus can be an equivalent to the water volume flow of fuel gas the gas fitting will flow.

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 an additional valve with which a Amplification factor between fuel gas volume flow and water volume flow set can be. This adjustment is usually done manually by the operator, often By means of a rotary knob and diverter, a linear valve opens continuously or closes. As a result, the outlet temperature of the continuous water heater 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 flow water heaters are usually relatively consuming, because the various functions have a mechanism with many deflections be achieved.

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 construction. The Zündgasführung 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) through a branching bore removed laterally and passed around the switching mechanism around to Zündgasventil. Since the drive for this Zündgasventil outside the gas-conducting area is located, 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, the factory setting or in the adjustment used an additional throttle on site to trim the maximum gas flow and thus to set the nominal power. Furthermore, per gas type and capacity different power preselector valves manufactured and assembled. At a gas type conversion On site, this valve must be replaced by another, in some cases even the complete gas valve is exchanged.

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 claim 1, the fuel gas to Zündgasventil by the Inside the main gas valve led. Since this is sealed from the environment, small leaks would result in no fuel gas leakage into the environment.

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 claim 2, the ignition gas is through the same leadership as led the mechanical actuating mechanism of the safety valve. hereby existing holes and cavities are used twice.

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.A further advantage of an advantageous embodiment of the invention is according to claim 5, that the gas fitting at factory or on-site without installation of an additional Throttle through an already existing, from the outside - to compensate for Manufacturing tolerances and to different power ratings, network pressures and gas types - adjustable valve can be adjusted. By the elimination of an additional throttle the pressure loss of the gas fitting is kept to a minimum. Furthermore, can In addition to the rated power and the partial load can be adjusted. In the manufacturing process will only still a universal power selector valve installed, which in the case of Gasartenumstellung at the customer no longer needs to be expanded and exchanged. In order to Costs can be saved and the device is due to the increased flexibility for the Customers significantly more attractive.

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. The power preselector valve cone is in addition to the multi-level power preselection per se infinitely and sensitively displaceable and thus adjustable. This becomes possible because of a Axial contact on a shaft by turning the adjusting screw via a clamp can be moved. The adjusting screw is coaxial with the gas control mechanism directly behind the gas button, so that their 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

Fig. 1 bis Fig. 16 die erfindungsgemäße Gasarmatur in verschiedenen Betriebssituationen sowie Details hiervon.Fig. 1 to Fig. 16, the gas valve according to the invention in different operating situations as well as details of this.

Figur 1 zeigt die erfindungsgemäße Gasarmatur in der diagonalen Draufsicht mit dem Bedienknopf 1 an der Vorderseite, der seitlichen Aufnahmebohrung 43 für den Wasserschalter, dem rückseitigen Gaseingang 44, dem ebenfalls rückseitigem Thermomagneten 48, dem Gasausgang 45 zum Brenner, dem Messnippel 47 zum Messen des Eingangsdrucks, dem Messnippel 39 zum Messen des Brennerdrucks sowie dem Zündgasausgang 26. Die Figuren 2a und 2b zeigen die erfindungsgemäße Gasarmatur aus anderen Perspektiven ebenfalls in diagonaler Draufsicht.Figure 1 shows the gas valve according to the invention in the diagonal top view with the Control knob 1 at the front, the lateral receiving bore 43 for the Water switch, the rear gas inlet 44, also back 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 Zündgasausgang 26. Figures 2a and 2b show the gas valve according to the invention other perspectives also in diagonal top view.

Figur 3 zeigt die erfindungsgemäße Gasarmatur im Schnitt A - A gemäß Figur 1. Die Gasarmatur befindet sich im Ausgangszustand, in dem kein Brenngas strömt. Der Bedienknopf 1 befindet sich in der Ausgangsstellung. Das Sicherheitsventil 2 mit dem Thermomagneten 48, das Zündgasventil 3, das Hauptgasventil 4 zur Leistungsvorwahl, das einen Leistungsvorwahlventilteller 23 umfasst, und das Wassermangelventil 5, das nicht in Figur 3, sondern z.B. in Figur 8 zu sehen ist, sind geschlossen. Über den Gaseingang 44, der in Figur 3 nicht zu erkennen ist, liegt Brenngas links vor dem Sicherheitsventil 2 an.FIG. 3 shows the gas fitting according to the invention in section A - A according to FIG Gas valve is in the initial state, in which no fuel gas flows. Of 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 the power selector, the a power preselector valve plate 23, and the water shortage valve 5 not in Figure 3, but e.g. can be seen in Figure 8, are closed. Via the gas inlet 44, which can not be seen in Figure 3, fuel gas is on the left in front of the safety valve 2.

Gemäß Figur 4 wird durch Linksdrehung des Bedienknopfes 1 im Gegenuhrzeigersinn die Gasarmatur in die Zündstellung gebracht. Über die Welle 6 wird die Drehbewegung des Bedienknopfes 1 auf ein Radialschaltstück 10 übertragen. Durch die Einstellschraube 8 können axiale Bewegungen des Bedienknopfes 1 auf eine Zwischenwelle 51 und einen damit verbundenen Stift 7 übertragen werden. Das Radialschaltstück 10 verfügt über eine Steuerkurve 21 (vgl. Figur 14), wodurch der radiale Anstieg der Steuerkurve 21 bei einer Rotationsbewegung im Gegenuhrzeigersinn eine Anhebung des Zündgasventiltellers 11 gegen die Feder 12 bewirkt. Ein Zündgasfilter 13 wird etwas komprimiert. Eine Flachdichtung 14 hebt von einem Zündgasventilsitz 15 ab.According to Figure 4 is by turning counterclockwise the control knob 1 counterclockwise Gas valve brought into the ignition position. About the shaft 6, the rotational movement of Control knob 1 transmitted to a radial contact 10. By the adjusting screw 8 can axial movements of the control knob 1 on an intermediate shaft 51 and a associated pin 7 are transmitted. The radial contact piece 10 has a Control cam 21 (see Figure 14), whereby the radial increase of the control cam 21 at a Rotational movement in the counterclockwise direction raising the Zündgasventiltellers 11th effected against the spring 12. A Zündgasfilter 13 is slightly compressed. A Flat gasket 14 lifts off from a Zündgasventilsitz 15.

Aus Figur 5 geht hervor, dass im nächsten Bedienschritt der Bedienknopf 1 mit der Welle 6 gegen die Feder 16 gedrückt wird. Die Einstellschraube 8, die Klammer 17 (siehe auch Fig. 15), das Radialschaltstück 10, der Stift 7 und ein Axialschaltstück 9 werden dabei ebenfalls verschoben. Der Stift 7 trifft auf den Ventilteller 18 des Thermomagneten 48 und hebt gegen den Druck der Feder 49 die Flachdichtung 19 vom Ventilsitz 20 ab. Das Brenngas kann nun durch einen Spalt 22 zentrisch durch den Leistungsvorwahlventilteller 23 hindurch in die Kammer 24 strömen. Von dort findet das Brenngas durch den Spalt 25 den Weg über den Zündgasfilter 13 zum Zündgasausgang 26.From Figure 5 shows that in the next operating step, the control knob 1 with the shaft. 6 is pressed against the spring 16. The adjusting screw 8, the bracket 17 (see also Fig. 15), the radial switch 10, the pin 7 and a Axialschaltstück 9 are also doing postponed. The pin 7 strikes the valve plate 18 of the thermomagnet 48 and raises against the pressure of the spring 49, the gasket 19 from the valve seat 20 from. The fuel gas can now through a gap 22 centrally through the power preselector valve plate 23 into the Flow chamber 24. From there, the fuel gas through the gap 25 the way over the Zündgasfilter 13 to Zündgasausgang 26th

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 at Ignition gas burner was ignited, after a short wait from the flame Thermostrom be tapped. This thermal current is on the thermomagnet 48 passed, whereby the thermomagnet 48, the valve plate 18 to the thermomagnet 48 against the spring 49 pulls. The control knob 1 can now be released by the operator. As a result, the parts slide control knob 1, shaft 6, radial contact piece 10, adjusting screw 8, Clamp 17, Axialschaltstück 9 and pin 7 due to the force of the spring 16 back into the Starting position. The ignition gas continues to flow.

Zur Leistungsvorwahl wird gemäß Figur 6 - während das Zündgas weiterhin fließt - der Bedienknopf 1 im Gegenuhrzeigersinn in die erste Raste gedreht, was der niedrigsten Stufe der Leistungsvorwahl entspricht. Dieser Bewegung folgen die Teile Welle 6, Radialschaltstück 10, Einstellschraube 8, Stift 7, Klammer 17 und Axialschaltstücks 9. For power preselection is in accordance with Figure 6 - while the ignition gas continues to flow - the Control knob 1 is turned counterclockwise in the first notch, which is the lowest level the power code corresponds. This movement is followed by the parts shaft 6, Radial switch piece 10, adjusting screw 8, pin 7, clamp 17 and Axialschaltstücks 9.

Da Gleitschuhe 28 der Axialschalthülse 27 (vgl. Fig. 16) in in Längsrichtung verlaufende Nuten im Gehäuse 30 sitzen, ist nur eine axiale Bewegung der Axialschalthülse 27 möglich. Die Axialschalthülse 27 verfügt über eine Rastnase 29 (vgl. Fig. 16), welche mit der Schaltkurve 31 oder den Kerben 32 des rotierenden Axialschaltstücks 9 (vgl. Fig. 15) in Berührung ist. Somit führt die Rotationsbewegung des Bedienknopfes 1 zu einer axialen Bewegung des Axialschaltstücks 27 gegen die Feder 16. Die Rastnase 29 (vgl. Fig. 16) gleitet entlang der Schaltkurve 31 (vgl. Fig. 15) bis sie in die erste Kerbe 32 (Fig. 15) einrastet. Dieser Bewegung folgt auch der Leistungsvorwahlventilteller 23 und die Flachdichtung 33, welche vom Ventilsitz 34 abhebt. Dadurch wird - definiert durch den Spalt 35 - einer bestimmten Brenngasmenge der Durchfluss durch einen Zwischenraum 50 bis zum Wassermangelventil 5 (vgl. Fig. 8) gewährt.Since sliding blocks 28 of the Axialschalthülse 27 (see Fig .. 16) extending in the longitudinal direction Sitting grooves in the housing 30, only an axial movement of the Axialschalthülse 27 is possible. The Axialschalthülse 27 has a locking lug 29 (see Fig .. 16), which with the Switching cam 31 or the notches 32 of the rotating Axialschaltstücks 9 (see Fig .. 15) in Touch is. Thus, the rotational movement of the control knob 1 leads to an axial Movement of the Axialschaltstücks 27 against the spring 16. The locking lug 29 (see Fig. 16) slides along the switching cam 31 (see Fig. 15) until it enters the first notch 32 (Fig. locks. This movement is also followed by the power preselector valve plate 23 and the Flat seal 33, which lifts off the valve seat 34. This is - defined by the gap 35 - a certain fuel gas flow through a gap 50 to granted to the water shortage valve 5 (see Fig. 8).

Während Figur 6 die Stellung des Leistungsvorwahlventiltellers 23 für die niedrigste Leistungsstufe zeigt, zeigt Figur 7 den Zustand, bei dem der Bedienknopf 1 über Zwischenstellungen bis zur höchsten Leistungsstufe im Gegenuhrzeigersinn gedreht wurde, wodurch die Rastnase 29 in die letzte Kerbe 32 des Axialschalstücks 9 eingreift. Der Leistungsvorwahlventilteller 23 gibt nun den maximalen Strömungsquerschnitt frei.While Figure 6 shows the position of the power selector valve plate 23 for the lowest Shows power level, Figure 7 shows the state in which the control knob 1 via Intermediate positions was turned counterclockwise up to the highest power level, whereby the detent 29 engages in the last notch 32 of the Axialschalstücks 9. Of the Power preselector valve plate 23 now releases the maximum flow cross section.

Wird in dieser sogenannten Bereitschaftsstellung Wasser gezapft, wird einen bekannten hydraulischen Vorgang im Wasserschalter die Membrane bewegt und über den Stift 36 (vgl. Fig. 8) und Einstellschraube 37 (Fig. 8) das Wassermangelventil 5 (Fig. 8) gegen die Feder 38 (Fig. 8) entsprechend der Wasserdurchflussmenge geöffnet. Die Einstellschraube 37 (Fig. 8) kann nur bei geöffnetem Gehäuse und somit nur außer Betrieb betätigt werden. Der Hauptbrenngasstrom strömt gemäß Figur 9 durch das geöffnete Wassermangelventil 5 vom Zwischenraum 50 durch den Gasausgang 45 am Gehäuse zum Brenner, wo das Gas - Luft - Gemisch von der brennenden Zündflamme entzündet wird. If water is tapped in this so-called readiness position, becomes a well-known hydraulic process in the water switch the diaphragm moves and over the pin 36 (see. 8) and adjusting screw 37 (Figure 8), the water shortage valve 5 (Figure 8) against the spring 38 (FIG. 8) opened according to the water flow rate. The adjusting screw 37 (Figure 8) can only be operated with the housing open and thus only out of service. Of the Hauptbrenngasstrom flows according to Figure 9 through the open water deficiency valve 5 from Space 50 through the gas outlet 45 on the housing to the burner, where the gas - air - Mixture is ignited by the burning pilot flame.

Die Figuren 10 und 11 veranschaulichen die Anpassung des Hauptgasventils 4 an unterschiedliche Fertigungstoleranzen, Leistungsgrößen, unterschiedliche Netzdrücken und Brenngasarten.FIGS. 10 and 11 illustrate the adaptation of the main gas valve 4 different manufacturing tolerances, performance variables, different network pressures and Fuel gas species.

Zur Anpassung wird der Bedienknopf 1 wird in eine definierte Stufe gedreht und anschließend abgezogen. Durch das Zapfen von Wasser wird das Gerät gestartet, während der Brennerdruck durch Messen am Druckmessnippel 39 (vgl. Fig. 1) fortlaufend gemessen wird.To adjust the control knob 1 is rotated in a defined level and subsequently deducted. By tapping water, the device is started while the burner pressure is continuously measured by measuring at the pressure measuring nipple 39 (see Fig. 1) becomes.

Durch Drehen der Einstellschraube 8 verändert sich deren axiale Position in der Zwischenwelle 51 und über den umlaufenden Einstich 40 folgen auch die U-förmige Klammer 17, die Teile Axialschaltstück 9, Feder 16, Axialschalthülse 27 und schließlich auch der Leistungsvorwahlventilteller 23. Dadurch verändert sich der Ventilspalt 35 solange, bis der gewünschte Brennerdruck erreicht wird.By turning the adjusting screw 8 changes its axial position in the Intermediate shaft 51 and the circumferential groove 40 also follow the U-shaped Clamp 17, the parts Axialschaltstück 9, spring 16, Axialschalthülse 27 and finally the power preselector valve plate 23. As a result, the valve gap 35 changes until the desired burner pressure is achieved.

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 (Fig. 3) zwischen Welle 6 und Gehäuse wird nur beim Zündvorgang axial beansprucht. Schraubende Bewegungen treten nicht auf.Other features are that during the adjustment process by the adjusting screw 8, the axial Position of the control knob 1 does not change. The position of the adjusting screw 8 must due to the self-locking are not secured against self-loosening. The Spring 16 works in two ways (previous systems use two for this purpose) Springs): Once during the ignition, when the control knob 1 against the spring 16 is pressed, and then upon release of the button 1 so that the mechanism with Wave and button is reset. On the other hand, when opening and closing the Power preselection valve plate 23. The adjustment is sensitive and infinitely variable. The dynamic seal (Fig. 3) between the shaft 6 and housing is only during the ignition process axially stressed. Screwing movements do not occur.

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 faucet with electric Ignition. There is no pilot flame, the main gas is electronically directly at Spigot of water ignited (direct starter). The flame detection (fuse) takes place through an ionization electrode. The thermo-electromagnet is powered by an electric Motor valve replaces which by power supply of battery or generator independently opens and closes. The aforementioned, adjustable from the outside Power selector valve 'is also used in this variant with the same benefits.
