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 fittings for a gas heating oven or the like are available in a large number of designs. They are used to ignite and regulate a gas flow flowing to a burner. Since the installation position is often unfavorable for adjustment, there are now solutions that use electronics.
- an electromagnet is briefly energized with a voltage pulse, whereby an actuating rod aligned with the ignition safety valve can be moved in the longitudinal direction against the force of a return spring so that the ignition safety valve, whose valve disk is mounted on a valve rod and loaded by a return spring in the closing direction is, opens and creates the armature of the ignition safety magnet, 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 the gas flow has been ignited.
- the winding of the ignition fuse Neten on the one hand in the circuit of a thermocouple heated by the pilot light and on the other hand can be controlled via the electronic control unit.
- a further embodiment of a gas ignition device for electrically controlling the ignition of a gas burner is known.
- a solenoid is connected to a mains voltage source by means of a switch.
- a gas valve is opened via an actuator, so that the gas can flow to the burner, where it is ignited electrically.
- the solenoid is disconnected from the mains and the actuator returns to its starting position.
- the gas valve is kept open by a magnet unit, which is supplied with current by a thermocouple under the action of the burning gas flame.
- the gas ignition device can be equipped with an additional battery with which operation can be maintained to a limited extent, or the actuating element can be used for the same reason manually operated to open the gas valve.
- the invention is based on the problem of allowing gas control fittings with electronic ignition of the gas flow to also be used for manual ignition. An unwanted manual operation should be prevented. Furthermore, safety should be ensured regardless of the type of ignition, in particular the main gas flow to the burner should be interrupted during ignition. Furthermore, the gas control valve should have the simplest possible structure.
- a cover element is mounted on the housing, which in a first position has a plunger for actuating a thermoelectric ignition safety valve and a main valve, which plunger protrudes from the gas-carrying space of the housing and in the longitudinal direction against the force of a return spring an electromagnet can be actuated and covers a button of a piezoelectric ignition element.
- an actuation of the tappet that is forced upon the adjustment of the cover element ensures that the main valve is in the closed position.
- the button and the plunger are released in such a way that the gas flow can be ignited by manual actuation thereof.
- An advantageous embodiment of the gas control valve is obtained if the cover element has a sliding track, the slope of which is set such that the main valve is in the closed position in the second position. It is particularly helpful for handling if the slide track additionally has a detent for the first and the second position of the cover element.
- the solution is particularly simple if the cover element is disk-shaped and is mounted centrally and rotatably on a pin.
- the cover element is provided with clearances that release the button and the plunger in the second position.
- the tappet is made in several parts.
- FIG. 1 shows an embodiment of a gas control valve according to the invention in a partially sectioned view in the closed position with the “electronic ignition” setting
- FIG. 2 shows an embodiment of a gas control valve according to the invention in a partially sectioned view in the ignition position with the “manual ignition” setting
- FIG. 3 shows an embodiment of a gas control valve according to the invention in a partially sectioned illustration in the open position
- FIG. 4 shows a view A of the gas control valve according to the invention from FIG. 1,
- FIG. 5 shows a view B of the gas control valve according to the invention from FIG. 2.
- the exemplary gas control fitting according to the invention shown in FIG. 1 is a switching and control device which is preferably intended for installation in a gas-heated stove or the like. It enables operation and
- the burner in this embodiment consists of a pilot burner, not shown, and a main burner, also not shown.
- This gas control valve consists of a housing 1, in which there are various functional units, which can be operated in part via operating elements from the outside.
- the housing is composed of an upper part 2 and a lower part 3, between which a flat seal 4 ensures the external tightness, and a cover 5.
- the housing 1 has a gas inlet 6, an ignition gas outlet 7 and a main gas outlet 8.
- An electronic control unit (not shown), which is located together with a voltage source in a separate location-independent housing of a remote control, is used for control.
- an actuating rod 10 is guided in a longitudinally movable manner in a bearing 9 of the housing 1, the end of which extends into the interior of the housing 1, the necessary gas tightness being ensured, for example, by round rings 11.
- An electromagnet 12 which can be actuated by means of the remote control is fastened between the upper part 2 and the cover 5. Furthermore, In this room there is a piezoelectric ignition element which can be operated manually via a button 13 which protrudes from the cover 5.
- the electromagnet 12 there is a core 14 which is movable axially to the actuating rod 10 and which forms a plunger 10/14 together with the actuating rod 10.
- the reason for the split of the tappet 10/14 is the resulting simplified installation option.
- the end face of the core 14 facing away from the housing 1 is visible through a recess 15 located in the cover 5.
- a disk-shaped cover element 17 is rotatably mounted, which on its underside has a guide track 18 acting on the core 14.
- a first latching position (FIG. 4)
- the cover element 17 closes the button 13 and the recess 15, whereas in a second latching position (FIG. 5) which results from rotation, the button 13 and the core 14 of the electromagnet 12 are closed in the cover element 17 frankings 32/33 are freely accessible.
- a valve plate 20 belonging to a main valve 19 is displaceably guided under the force of a closing spring 21, which rests on the one hand on the upper part 2 and on the other hand on the valve plate 20, on the one Actuating rod 10 supports stop 22, which is formed, for example, by a locking washer attached to a groove.
- the movement of the actuating rod 10 in the longitudinal direction is only possible against the force of a return spring 23 which is supported in the housing 1.
- the starting position to be assumed under the force of the return spring 23 is achieved in that the valve plate 20 of the main valve 19 rests on the upper part 2.
- the interior of the part of the housing 1 formed by the upper part 2 and lower part 3 is divided by a partition 24 into different rooms. Aligned in the extension of the actuating rod 10, the partition 24 has an opening, whose side facing the upper part 2 forms the valve seat 25 for the valve plate 20, and thus in connection with this forms the main valve 19, while the other side forms a valve seat 28 associated with an ignition protection valve 26. Between the two valve seats 25/28 one opens into the opening Ignition gas outlet 7 leading ignition gas bore 34.
- the ignition safety valve 26 is influenced by a thermoelectric ignition safety magnet 27 which is arranged in a gas-tight manner in a bearing point of the housing 1 and is located downstream of the gas inlet 6.
- thermoelectric ignition safety magnet 27 acts on an armature which is rigidly connected to a valve rod 29 on which the valve plate 30 of the ignition safety valve 26 is fastened.
- the thermoelectric ignition safety magnet 27 can be excited via the electronic control unit and via a thermocouple exposed to the pilot flame.
- the structure and the mode of operation of the ignition safety magnet 27 are otherwise familiar to the person skilled in the art, so that the description of further details can be dispensed with. It is only to be emphasized that a return spring 31 strives to pull the armature from the ignition safety magnet 27 via the valve plate 30 serving as a spring bearing.
- a switch Inside the housing 1, which controls the amount of gas flowing to the main burner.
- the switch is designed in such a way that modulating control is effected via a first valve with a sudden switching on and off in the part-load range via a second valve.
- the partial load flow is limited by an adjustable nozzle.
- a longitudinally movable plunger which is in a non-positive connection with the switch, protrudes from the housing 1 which at the same time forms a bearing point for it.
- a round ring for example, ensures the necessary gas tightness to the outside. With its end facing away from the switch, the plunger is connected to an operating element 35.
- the operating element 35 has a toothing in the region of its outer circumference, in which a pinion belonging to a transmission gear engages.
- the transmission gear is with a drive unit attached to the housing 1 36 coupled, which consists of an electric motor.
- a slip clutch known to the person skilled in the art and therefore not explained in more detail is arranged between the drive unit 36 and the operating element 35.
- the drive unit 36 is controlled by means of the remote control via the electronic control unit.
- the electronic control unit When the gas control valve is functioning normally, the electronic control unit is operated via the remote control. This actuates the electromagnet 12 by means of an electrical pulse such that the actuating rod 10 is moved in the direction of the ignition safety valve 26 by the core 14. First, the main valve 19 is closed and then the ignition safety valve 26 is opened so far that the armature is in contact with the ignition safety magnet 27 (FIG. 2). In addition, the ignition safety magnet 27 is excited via the electronic control unit, so that from the time the armature strikes the ignition safety magnet 27, the armature is held in this position by the flowing holding current, i.e.
- pilot gas can now flow via the pilot gas bore 34 to the pilot gas outlet 7 and from there via a pilot gas line (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 in that the second valve suddenly opens.
- the constant amount of gas limited by an opening 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 drive unit 36 the amount of gas flowing to the main gas burner is increased evenly, since the first valve now opens continuously, thereby increasing the through the first valve flowing gas quantity is reached until the maximum gas amount is reached.
- the core 14 is moved so far in the longitudinal direction by the link path 18 that the main valve 19 is closed by the actuating rod ⁇ 0.
- the actuating rod 10 is now pushed in by hand to the extent that the ignition safety valve 26 opens (FIG. 2).
- the button 13 of the piezoelectric ignition device is actuated and the ignition gas is ignited with the resulting spark.
- thermocouple After the thermocouple has been heated by the burning pilot flame so that the necessary holding current is available, the force acting on the core 14 can be ended and the cover element 17 can be brought into the position shown in FIG. 4. Under the force of the return spring 23, the actuating rod 10 and the button 13 assume their starting position.
- the main valve 19 is opened and the ignition safety valve 26 is held in a known manner by the thermoelectric ignition safety magnet 27 (FIG. 3).
- the control element 35 By manual actuation of the control element 35, the amount of gas flowing to the main burner can now be set via the switch.
