Definitions

  • the invention relates to a gas control valve with electronic ignition for a gas-fired heating device according to the preamble of the first claim.
  • Gas control valves for a gas fired heater such as a gas heater or the like, are available in a variety of designs. They serve to ignite and to control a gas flow flowing to a burner.
  • an ignition safety magnet is triggered by generating a holding current provided by a voltage source for keeping open a gas flow blocking the thermoelectric ignition safety valve.
  • an electromagnet is briefly energized with a voltage pulse, whereby an aligned for Zünd Anlagensventil actuating rod so far in the longitudinal direction against the force of a return spring is movable, that the Zündtechnischsventil whose valve plate mounted on a valve rod and loaded by a return spring in the closing direction is, opens and thereby applies the armature of the Zündtechnischsmagneten, which is firmly connected to the valve rod.
  • the armature is held by the holding current coming from the voltage source until a thermocouple provides the necessary holding current after ignition of the gas flow.
  • the winding of the Zündtechnischsmagneten one hand in the circuit of a from the pilot flame heatable thermocouple and on the other hand can be controlled via the electronic control unit.
  • a cover is movably mounted on the housing of the gas control valve, which covers in a first position serving to actuate a thermoelectric Zünd Anlagensventils and a main valve plunger and a probe of a piezoelectric ignition element.
  • a second position of the cover is ensured by a forcibly during the adjustment of the cover member actuation of the plunger that the main valve is in the closed position.
  • the push button and the plunger are released in such a way that a manual actuation of the same makes it possible to ignite the gas flow.
  • the invention is based on the problem in a gas control valve with electronic ignition of the gas stream to ensure a simple manual operation according to the preamble of the first claim. In particular, switching on and off should be made possible with one movement each.
  • the problem is solved in that a microswitch connected to the electronic control unit is arranged on the housing and, in the case of manual actuation of the plunger in the longitudinal direction against the force the return spring is actuated.
  • the electronic control unit receives an electrical signal, whereby activation of the same and thus ignition of the flowing through the open Zünd Anlagensventil gas flow takes place when switched off the gas control valve, whereas in the already switched on state of Gasregelarmatur an interruption of the thermoelectric ignition valve flowing holding current and thus a deactivation the gas control valve takes place.
  • the gas control valve when a display is arranged on the housing, via which the operating state can be displayed.
  • This can be, for example, an LED that lights up when the gas control valve is switched on.
  • the exemplary gas control valve according to the invention shown in the figures is a switching and control device which is intended for installation in gas-operated heating devices or the like. It enables the operation and monitoring of a burner by controlling the amount of gas flowing to the burner.
  • the burner consists in this embodiment of a pilot burner, not shown, and a main burner, also not shown.
  • To control serves an electronic control unit, not shown, which is located in this example, together with a voltage source in a separate location-independent housing, not shown.
  • a plunger 10 For commissioning a plunger 10 is longitudinally movably guided in a bearing point 9 of the upper part 2, which extends with its end into the interior of the housing 1, for example, by round rings 11, the necessary gas tightness is ensured.
  • the movement of the plunger 10 in the longitudinal direction is possible only against the force of a support in the upper part 2 return spring 16.
  • a control element 13 On the outwardly projecting end of the plunger 10, a control element 13 is attached, which has a switching contour 14 on its lateral surface. Between upper part 2 and cover 5, a microswitch 12 is further attached, the switching element 15 is actuated via the switching contour 14.
  • the starting position to be assumed under the force of the return spring 16 is achieved in that the valve disk 20 of the main valve 19 bears against the upper part 2.
  • the interior of the upper part 2 and lower part 3 formed part of the housing 1 is divided by a partition wall 24 into different rooms. Escaping in extension of the plunger 10, the partition wall 24 has an opening 17, the upper part 2 facing side of the valve seat 25 for the valve disc 20, and thus in conjunction with this, the main valve 19, while the other side of the opening 17 to a Zündracsventil 26 associated valve seat 28 forms. Between the two valve seats 25/28 opens into the opening 17 leading to Zündgasausgang 7 Zündgasbohrung 18.
  • the Zündschsventil 26 is influenced by a gas-tight in a bearing of the housing 1 thermoelectric Zündtechnischsmagneten 27, which is located downstream of the gas inlet 6.
  • thermoelectric Zündschsmagnet 27 acts on an armature which is rigidly connected to a valve rod 29, on which the valve disc 30 of the Zündtechnischsventils 26 is attached. Via the electronic control unit as well as via a thermocouple exposed to the pilot flame, the thermoelectric ignition safety magnet 27 can be excited.
  • the construction and mode of operation of the ignition-securing magnet 27 are familiar to the person skilled in the art, so that it is possible to dispense with the description of further details. It should be emphasized only that a return spring 31 strives to deduct the armature on the serving as a spring bearing valve plate 30 from the ignition fuse magnet 27.
  • the housing 1 In the flow direction behind the startup is located within the housing 1, not shown, as known to those skilled control unit for the gas flowing to the main burner gas. It usually consists of a switch which controls the amount of gas flowing to the main burner.
  • the switch is designed, for example, so that a modulating control is effected via a first valve with jump-like switching on and off in the partial load range via a second valve.
  • the partial load flow is limited by an adjustable nozzle.
  • a longitudinally movable actuating rod which is connected to the switch and projects longitudinally, protrudes from the housing 1, which simultaneously forms a bearing for it, and is connected to a control element 23.
  • an LED 32 which is connected to the electronic control unit and connected so that it lights up when the gas control valve is turned on.
  • the operation of the gas control valve is as follows:
  • the gas control valve is shown in the off state.
  • the operating element 13 is under the action of the return spring 16 in its initial position.
  • the main valve 19 is indeed open, but the Zündtechnischsmagnet 27 is not energized, so that the Zündtechnischsventil 26 is closed and no gas can flow to the burner.
  • the main valve 19 is first closed and then the ignition safety valve 26 is opened so far that the armature on Zünd Anlagensmagneten 27 is present.
  • the ignition gas can now flow to the Zündgasausgang 7 via the Zündgasbohrung 18 and from there via a Zündgas effet, not shown, to the pilot burner.
  • the switching element 15 of the microswitch 12 is actuated via the switching contour 14 and ignited via a signal sent to the electronic control unit electrical signal through this gas flowing out of the pilot burner.
  • the switch can be actuated in a known manner, by first causing a sudden opening of the second valve.
  • the limited by an opening constant amount of gas flows through the main gas outlet 8 through a main gas line also not shown to the main burner and is ignited via the pilot flame.
  • the flames burn with a minimum height.
  • the amount of gas flowing to the main gas burner is increased uniformly, since now the first valve opens continuously, whereby a uniform increase in the amount of gas flowing through the first valve is achieved.
  • the main valve 19 is closed and thus the gas flow to the main burner is interrupted.
  • an electrical signal is again interrupted to the electronic control unit and via this the power supply from the thermocouple to the Zündtechnischsmagneten 27.
  • the Zündtechnischsventil 26 is no longer held by the Zündtechnischsmagneten 27 and goes into the closed position as soon as the control element 13 is no longer actuated and goes back to its original position. Furthermore, the LED 32 goes out.
  • the gas control valve is in the deactivated state.
  • control unit for the gas flowing to the main burner gas quantity can be omitted, if always a constant amount of gas to flow to the main burner and it is not necessary to control this gas flow.
  • the gas control valve for example, even more functional units, such as a pressure regulator or the like, have.
  • the electrical signal sent to the electronic control unit can additionally be used, for example, to provide the necessary holding current initially by a voltage source. until the thermocouple is activated.
