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 fittings for a gas fired heater such as a gas heater, a gas chimney or the like, are available in a variety of designs. They serve to ignite and to control a gas flow flowing to a burner.
  • the invention is based on the problem in a gas control valve with electronic ignition of the gas stream according to the preamble of the first claim to ensure a simple manual operation by switching on and off to be made possible with one movement. Furthermore, it should be ensured that switching off the gas control valve is ensured even in case of failure of the voltage source.
  • 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 becomes.
  • 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, wherein, for example, by a circular ring 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 12.
  • first micro-switch 13 which is electrically connected to the electronic control unit
  • second micro-switch 14 which is electrically connected in series in the thermal circuit, attached.
  • the microswitch 13 in the closed position of the gas control valve, the microswitch 13 is in the open position and the microswitch 14 is in the closed position.
  • switching contour 15 for the switching element 18 of the first microswitch 13 and a switching contour 16 for the switching element 19 of the second microswitch 14.
  • Both switching contours 15; 16 are located on the lateral surface of a control element 17 which is fixed on the outwardly projecting part of the plunger 10.
  • valve plate 21 On the projecting into the interior of the upper part 2 region of the plunger 10 is associated with a main valve 20 valve plate 21 slidably guided, which rests under the force of a closing spring 22, on the one hand on the upper part 2 and on the other hand on the valve plate 21, on a on the Plunger 10 located stop 23 is supported.
  • the starting position to be assumed under the force of the return spring 12 is achieved in that the valve disk 21 of the main valve 20 bears against the upper part 2.
  • a partition wall 24 By a partition wall 24, the interior of the upper part 2 and lower part 3 formed part of the housing 1 is divided into different rooms. Escaping in extension of the plunger 10, the partition wall 24 has an opening 32, the upper part 2 facing side of the valve seat 25 for the valve plate 21, and thus in conjunction with this, the main valve 20, while the other side of the opening 32 a to a Zündracsventil 26 associated valve seat 27 forms. Between the two valve seats 25; 27 opens into the opening 32 leading to Zündgasausgang 7 Zündgasbohrung 33.
  • the Zündschsventil 26 is influenced by a gas-tight in a bearing of the housing 1 thermoelectric Zündschungsmagneten 34, which is located downstream of the gas inlet 6.
  • thermoelectric Zündschsmagnet 34 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.
  • the thermoelectric ignition safety magnet 34 can be excited via the electronic control unit as well as via a thermocouple exposed to the pilot flame.
  • the construction and mode of operation of the ignition-securing magnet 34 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 Zünd Anlagensmagneten 34.
  • 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 out of the housing 1 forming a bearing for it at the same time and is connected to a control element 28.
  • the main valve 20 is first closed and then the ignition safety valve 26 is opened so far that the armature is applied to the Zündtechnischsmagneten 34.
  • the ignition gas can now flow to the Zündgasausgang 7 via the Zündgasbohrung 33 and from there via a Zündgastechnisch, not shown, to the pilot burner.
  • the first microswitch 13 is closed via the switching contour 15 and the switching element 18 and thereby achieved via an electrical signal sent to the electronic control unit, on the one hand via the first microswitch 13, a current is applied to the Zündêtsmagneten 34, and on the other hand via the electronic control unit ignited gas flowing out of the pilot burner. Furthermore, the switching element 19 of the second microswitch 14 is actuated via the switching contour 16, so that the microswitch 14 assumes its open position, whereby the thermal circuit is interrupted.
  • thermocouple which can be influenced by the pilot flame, but can not yet flow due to the interrupted thermo-current circuit.
  • the plunger Only when the manual operation of the operating element 17 is terminated, the plunger returns to its initial position, the main valve 20 is opened and the micro-switch 13; 14 are pressed. In this case, the opening of the first microswitch 13 takes place only after the second microswitch has already closed to ensure that the Zündtechnischsmagnet 34, now on the applied thermoelectric voltage, remains energized.
  • the switch can be operated in a known manner, by first comes to 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.
  • control element 17 If the control element 17 is actuated in the activated state of the gas control valve, the main valve 20 is closed and thus the gas flow to the main burner is interrupted. About the also simultaneously taking place of the microswitch 14, the thermal circuit is manually interrupted. The Zündtechnischsmagnet 34 is no longer energized and thus the Zündtechnischsventil 26 is no longer maintained. As soon as the control element 17 is no longer actuated and returns to its initial position, the ignition safety valve 26 also moves into the closed position. 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.
