Definitions

  • the invention relates to a method for igniting a gas stream and an arrangement for carrying out this method, as they can be used in gas control valves for a gas heating furnace.
  • Gas control valves for 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.
  • a valve device for controlling the ignition of a gas burner is known.
  • An actuating spindle is moved by hand to the ignition position, the ignition safety valve is opened.
  • the actuating spindle need only be kept in this position for a short time, since during the movement of the actuating spindle, a micro switch is turned on. This causes a power supply to provide a voltage to hold the magnetic insert. Ignition is via a piezoelectric spark ignition.
  • the power supply is switched off when the thermo-current supplied by a thermocouple is sufficient to hold the pilot-operated safety valve in the open position.
  • thermoelectric fuse for gas burners of heating systems described.
  • This multi-function valve uses the existing mains power supply of a room for its operation.
  • a solenoid valve is energized via a pushbutton, whereby the ignition safety valve is opened.
  • the ignition of the gas flow A thermocouple located in the area of the ignited gas flame is heated and brings about the resulting thermo-current a magnetic insert in the excited state.
  • the magnet holds an anchor and thus also connected to the armature ignition safety valve in the open position. Now the push button can be released and the solenoid valve de-energized.
  • the invention is based on the problem to develop a method for igniting a gas stream and an arrangement for carrying out this method, which enables ignition by means of a remote control. Furthermore, the necessary power consumption should be kept so low that an integrable voltage source can be used. Furthermore, the structure should be as simple as possible.
  • the problem is solved in that for igniting a gas stream by actuation of a voltage source fed by an electronic control unit, a Zünd Anlagensmagnet is triggered by generating a holding current for keeping open the gas flow shut-off thermoelectric Zünd Anlagensventils.
  • a solenoid is briefly energized with a voltage pulse, whereby an actuating rod opens the Zündtechnischsventil and thereby applies the armature of the Zündtechnischsmagneten.
  • 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 or a defined holding time is exceeded.
  • the arrangement for igniting a gas stream consists of a supplied from a voltage source electronic control unit, a gas flow blocking thermoelectric Zünd Anlagensventil, a Zünd Anlagensmagneten and an alignment for Zündêtsventil actuating rod.
  • the valve plate of the Zünd Anlagensventils is mounted on a valve rod and loaded by a return spring in the closing direction.
  • the armature of the ignition safety magnet is firmly connected to the valve stem.
  • the winding of the Zündtechnischsmagneten one hand, in the circuit of a heated by the gas flame thermocouple and on the other hand can be controlled via the electronic control unit.
  • the actuating rod aligned with the ignition safety valve is movable so far in the longitudinal direction against the force of a return spring by an electromagnet that the armature of the ignition safety magnet is in contact and the valve disk is in the open position.
  • the electromagnet is connected to the electronic control unit and excitable by a voltage pulse for the duration of the pulse.
  • a drive unit which controls the amount of gas flowing to a main burner via a switch.
  • An advantageous embodiment of the method is obtained when the aforementioned steps are skipped when already burning pilot flame and the electronic control unit drives a drive unit such that increases the gas flowing to the main burner gas quantity. Due to the fact that, when the ignition flame is burning, an increase in the amount of gas flowing to the main burner takes place automatically, the design and operation can be simplified.
  • the power source consists of a battery that can be made so small in size that they are located together with the electronic control unit in a remote control can.
  • exemplary gas control valve is a switching and control device, which is preferably intended for installation in a gas-fired stove 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 42 and a main burner 44th
  • This gas control valve consists of a housing 1, which has a gas inlet 2, a Zündgasausgang 3 and a main gas outlet 4.
  • a gas inlet 2 a gas inlet 2
  • a Zündgasausgang 3 a gas outlet 3
  • main gas outlet 4 a main gas outlet 4.
  • the housing 1 In the housing 1 are the individual functional units.
  • an actuating rod 10 is longitudinally movably guided in a bearing 9 of the housing 1, which is actuated via an arranged on the housing 1 electromagnet 11 by means of the remote control 6, for example, by round rings 12, the necessary gas tightness is ensured.
  • the movement in the longitudinal direction is possible only against the force of a support in the housing 1 return spring 13.
  • the starting position to be adopted under the force of the return spring 13 is achieved by means of an abutment 14 located on the actuating rod 10, which abuts in the starting position on a stop, not shown.
  • the actuating rod 10 extends with its end into the interior of the housing. 1
  • the interior of the housing 1 is divided by a partition wall 15 into different rooms.
  • the partition wall 15 has a first opening 16, which belongs to an ignition safety valve 17.
  • the ignition safety valve 17 is influenced by a gas-tightly arranged in a bearing of the housing 1 thermoelectric Zünd Anlagensmagneten 18, which is located downstream of the gas inlet 2.
  • the thermoelectric Zünd Anlagensmagnet 18 acts on an armature 19 which is rigidly connected to a valve rod 20 on which the valve plate 21 of the Zündtechnischsventils 17 is attached.
  • About the electronic control unit 5, as well as via a pilot flame exposed thermocouple 22 of the thermoelectric Zündtechnischsmagnet 18 can be excited.
  • a switch 24 In the flow direction behind the commissioning 7 is located within the housing 1, a switch 24.
  • the switch 24 has a one-sided double-slotted spring spring 25, on the one hand with its located on the slotted side two outer ends in a housing 1 located in the first bearing 26th supported, while on the other hand is connected with its non-slit side with a Lyrafeder 27, which is supported in a housing 1 located in the second bearing 28.
  • a first valve 29 associated with a first valve closing body 30 is mounted, which is assigned a located in the partition wall 15 first valve seat 31.
  • a second valve 32 associated, located in a second guide bore second valve closing body 33 is mounted on the located between the two outer ends resilient tongue of the spring spring 25, which is assigned a located in the partition wall 15 second valve seat 34.
  • the stroke of the switch is determined by the movement of the spring 25 limiting limiting stops not shown.
  • the switch 24 is designed so that a modulating control via the valve 32 with jump-like switching on and off in the partial load range via the valve 29 is effected.
  • the partial load flow is limited by the cross section of the opening 37 located in the partition wall.
  • a circular ring 39 By, for example, a circular ring 39, the necessary gas tightness is ensured to the outside.
  • the plunger 36 With its end facing away from the switch 24, the plunger 36 is connected to an unspecified, as known to those skilled drive unit 40.
  • the control of the drive unit 40 by means of the remote control 6 via the electronic control unit. 5
  • the drive unit 40 is additionally checked for safety reasons before ignition by the electronic control unit 5, whether the two valves 29/32 are closed or controlled so that both valves 29/32 are closed. Thereafter, the electromagnet 11 is actuated by means of an electrical pulse such that the actuating rod 10 is moved in the direction of the Zünd Anlagensventils 17 and this opens so far that the armature 19 is applied to the Zündtechnischsmagneten 18 ( Fig. 2 ).
  • the ignition safety magnet 18 is energized via the electronic control unit 5, so that from the time of impact of the armature 19 on the Zünd Anlagensmagneten 18 of the armature 19 by the flowing holding current in this position, that is held in the open position of the Zünd Anlagensventils 17, while the actuating rod 10 due to the de-energized after the completed pulse electromagnet 11 and under the action of the return spring 13 again assumes the starting position.
  • the ignition gas can now flow via the pilot gas line 41 to the pilot burner 42, where it is ignited by means of the ignition electrode 43. ( Fig. 3 ).
  • thermocouple 22 The burning pilot flame heats the thermocouple 22.
  • the resulting size of the thermo-current is checked by the electronic control unit 5. As soon as the thermo-current is sufficient to hold the armature 19, the holding current coming from the voltage source is switched off.
  • the holding current coming from the voltage source is switched off by the electronic control unit 5, as a result of which the ignition safety magnet 18 is de-energized and the ignition-securing valve 17 closes.
  • the drive unit 40 can be actuated via the remote control 6 and the electronic control unit 5.
  • the switch 24 opens in a known manner in that it comes to a sudden lifting of the valve closing body 30 from the valve seat 31.
