Definitions

  • the invention relates to a gas control valve with electronic ignition for a gas heating furnace according to the preamble of the first claim.
  • 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. Since the installation position for an adjustment is often unfavorable, there are now solutions in which electronics are used.
  • 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. This is the winding of the ignition fuse magnet on the one hand in the circuit of a heatable from the pilot flame thermocouple and on the other hand can be controlled via the electronic control unit.
  • a gas ignition device for electrically controlling the ignition of a gas burner known.
  • a magnetic coil is closed by a switch to a mains voltage source.
  • a gas valve is opened via an actuator, so that the gas can flow to the burner, where it is electrically ignited.
  • the solenoid is disconnected from the mains and the actuator returns to its original position.
  • the open position of the gas valve is taken over by a magnet unit which is supplied with power by a thermocouple under the action of the burning gas flame.
  • the gas ignition device may be equipped with an additional battery capable of maintaining operation to a limited extent, or the actuator may be manually operated for the same reason Opening the gas valve can be actuated.
  • the invention is based on the problem in gas control valves with electronic ignition of the gas stream to enable a manual ignition.
  • an unwanted manual operation should be prevented.
  • the gas control valve should have the simplest possible structure.
  • the problem is solved in that on the housing a cover is mounted, which serves in a first position for actuating a thermoelectric Zünd Anlagensventils and a main valve plunger, which protrudes from the gas-carrying space of the housing and in the longitudinal direction against the force of a return spring an electromagnet is actuated, and covers 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.
  • An advantageous embodiment of the gas control valve results when the cover has a slide track whose pitch is set so that in the second position, the main valve is in the closed position. Especially for handling, it proves to be helpful if, in addition, the slide track each has a detent for the first and the second position of the cover.
  • the solution is particularly simple if the cover is disc-shaped and mounted centrally and rotatably on a pin.
  • the cover is provided with clearances that release the button and the plunger in the second position.
  • 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, not shown, and a main burner, also not shown.
  • This gas control valve consists of a housing 1 in which various functional units, which can be partially operated via controls from the outside, are located.
  • the housing is composed of an upper part 2 and a lower part 3, between which a flat gasket 4 ensures the outer tightness, and a cover 5.
  • the housing 1 has a gas inlet 6, a Zündgasausgang 7 and a main gas outlet 8.
  • an actuating rod 10 is longitudinally movably guided in a bearing 9 of the housing 1, which extends with its end into the interior of the housing 1, for example, by round rings 11, the necessary gas tightness is ensured.
  • an actuatable by means of the remote control solenoid 12 is attached.
  • a piezoelectric ignition element which can be manually operated via a button 13, which protrudes from the cover 5.
  • the solenoid 12 is an axially movable to the actuating rod 10 core 14 which forms a plunger 10/14 together with the actuating rod 10.
  • Reason for the division of the tappet 10/14 is the resulting simplified assembly time.
  • the housing 1 facing away from the end face of the core 14 is visible through a located in the cover 5 recess 15.
  • a disc-shaped cover 17 is rotatably mounted, which has on its underside acting on the core 14 slide track 18.
  • a first detent position ( Fig. 4 ) closes the cover 17, the button 13 and the recess 15, whereas in a resulting upon rotation second detent position ( Fig. 5 ) of the button 13 and the core 14 of the electromagnet 12 are freely accessible through located in the cover member 17 clearances 32/33.
  • valve plate 20 On the projecting into the interior of the upper part 2 region of the actuating rod 10 associated with a main valve 19 valve plate 20 is slidably guided, which rests under the force of a closing spring 21, on the one hand on the upper part 2 and on the other hand on the valve disc 20, on a on Operating rod 10 located stop 22 is supported, which is formed for example by a plugged onto a groove lock washer.
  • the movement of the actuating rod 10 in the longitudinal direction is possible only against the force of a support in the housing 1 return spring 23.
  • the starting position to be assumed under the force of the return spring 23 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 actuating rod 10, the partition wall 24 has an opening, whose side facing the upper part 2 forms the valve seat 25 for the valve disk 20, and thus in connection therewith forms the main valve 19, while the other side forms a valve seat 28 associated with an ignition safety valve 26.
  • the Zünd Anlagensventil 26 is influenced by a gas-tight in a bearing of the housing 1 arranged thermoelectric Zünd Anlagensmagneten 27, which is located downstream of the gas inlet 6 in the opening.
  • 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.
  • a switch that controls the amount of gas flowing to the main burner.
  • the switch is designed so that a modulating control is effected via a first valve with sudden switching on and off in the partial load range via a second valve.
  • the partial load flow is limited by an adjustable nozzle.
  • a standing in a frictional connection with the switch and longitudinally movable plunger protrudes from the same time a bearing for him forming housing 1 out.
  • a round ring ensures the necessary gas tightness to the outside.
  • the operating element 35 With its end facing away from the switch of the plunger is connected to a control element 35.
  • the operating element 35 has, in the region of its outer circumference, a toothing in which engages a pinion associated with a transmission gear.
  • the transmission gear is attached to a housing 1 drive unit 36 coupled, which consists of an electric motor.
  • a housing 1 drive unit 36 coupled, which consists of an electric motor.
  • slip clutch arranged between the drive unit 36 and the operating element 35.
  • the control of the drive unit 36 by means of the remote control via the electronic control unit.
  • the electromagnet 12 is actuated by means of an electrical pulse such that the actuating rod 10 is moved in the direction of the ignition-securing valve 26 through the core 14.
  • the main valve 19 is first closed and then the ignition safety valve 26 is opened so far that the armature bears against the ignition safety magnet 27 (FIG. Fig. 2 ).
  • the Zündschsmagnet 27 is energized via the electronic control unit, so that from the time of impact of the armature on the Zünd Anlagensmagneten 27 the armature by the flowing holding current in this position, ie held in the open position of the Zünd Anlagensventils 27, while the actuating rod 10 due of the de-energized after the completed pulse electromagnet 12 and under the action of the return spring 23 again assumes the starting position.
  • the ignition gas can now flow through the Zündgasbohrung 34 to Zündgasausgang 7 and from there via a Zündgastechnisch not shown to the pilot burner, where it is ignited.
  • the drive unit 36 can be actuated via the electronic control unit.
  • the switch opens 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 achieved by the first valve gas flowing through until the maximum amount of gas is reached.
  • the cover 17, which is usually in the in Fig. 4 shown, the electronic ignition associated first detent position is located in the Fig. 5 rotated position shown.
  • the core 14 is moved so far in the longitudinal direction by the slide track 18 that the main valve 19 is closed by the actuating rod 10.
  • the actuating rod 10 is now so far pushed by manually exerted force on the front side of the core 14, that the Zünd Anlagensventil 26 opens ( Fig. 2 ). If the force is maintained, the button 13 of the piezoelectric ignition device is then actuated and ignited with the resulting spark ignition gas.
  • thermocouple After the thermocouple is heated by the burning pilot flame, so that the necessary holding current is available, the force can be exerted on the core 14 and the cover 17 in the in Fig. 4 shown position. Under the force of the return spring 23, the actuating rod 10 and the button 13 take their starting position.
  • the main valve 19 is opened and the Zündtechnischsventil 26 is held in a known manner by the thermoelectric Zündtechnischsmagneten 27 ( Fig. 3 ).
  • the control element 35 By manual operation of the control element 35, the amount of gas flowing to the main burner can now be adjusted via the switch.
