Definitions

  • the invention relates to valve control devices intended to supply pressurized combustible gas to the burners of gas appliances such as water heaters, bath heaters and boilers intended for central heating by circulation of hot water. in radiators.
  • valves in question are electrically controlled by a direct voltage
  • control devices those for which the valves in question are electrically controlled by a direct voltage
  • a capacitor having a capacity such that, from its electrically charged state, its discharge in the valve ensures opening thereof for a predetermined period of between 1 and 5 s
  • a two-position switch mounted in such a way that, for a first position of this switch, the capacitor is charged from a source of electric voltage and that, for the second position of said switch, the capacitor is discharged towards the valve
  • the new means in question still involve the capacitor and are arranged so as to subject the latter to an uninterrupted periodic series of recharges by the source and discharges in the valve. . -
  • This solution which requires an uninterrupted series of openings and closings of electrical circuits enslaved to each other is complicated, expensive and above all its reliability is questionable.
  • the invention aims, above all, to propose to constitute the new means in question a particularly simple, robust and reliable solution.
  • the source is a source of alternating electrical voltage and the new means comprise a first unidirectional member interposed between this source and the switch in the direction allowing the charging of the capacitor from the source, a second unidirectional member interposed between the switch and the valve in the direction allowing the discharge of the capacitor in this valve, and a conductive section interposed between a first point located between the source and the first unidirectional member and a second point located between the second unidirectional member and the valve , this section itself comprising, on the one hand, a third unidirectional member mounted in the direction allowing the supply of the valve through it from the source and, on the other hand, an electric switch controlled by the effective gas ignition.
  • the capacitor its capacity is relatively high: this is how, if the supply voltage of the device is the AC mains voltage at 220 V and if the electric power consumed by the valve is of the order from 5 to 50 W, the capacity of this capacitor is between 100 and 1000 uF, said capacitor preferably being of an electrochemical type.
  • the invention includes, apart from these main provisions, certain other provisions which are preferably used at the same time and which will be more - explicitly discussed below.
  • the single figure of this drawing shows, very schematically, a device established according to the invention for controlling the fuel gas supply valve of a central heating boiler with hot water.
  • valve in question has been designated by reference 1 on this diagram.
  • the capacitor 3 is in particular of the electrochemical type and its capacity depends on the voltages involved and on the electric power consumed by the valve for its opening: in the case where the source 2 is the sector, that is to say a source of alternating voltage at 220 V, if the power in question is of the order of ten W, said capacity is between 300 and 400 ⁇ F, but, all things also equal, said capacity would be 100 times higher if the supply voltage had a value 10 times lower.
  • the period T 0 is generally between 1 and 5 s and is preferably of the order of 3 seconds.
  • the switch 4 At rest, that is to say when the valve 1 is closed and no gas flow is therefore delivered to the device, the switch 4 is in its first position, which has been illustrated in solid lines on the drawing, for which the capacitor 3 is connected to the source 2; if the main switch 7 is closed, this capacitor then charges electrically to the maximum through components 5 and 8.
  • the ignition control results in the switching of the switch 4 from its above position to its second position, illustrated in dashes: the capacitor 3 is immediately discharged into the valve 1 through the component 6, which opens this valve , and this during period T.
  • the response time of the chain F, 13, 15, G, 11 is less than the period T 0 , so that, if the gas supplied by the burner 14 is correctly ignited, the electrical supply to the valve 1, initiated by the discharge of the capacitor 3, is relayed by the source 2 through the elements 9, 10, 11 before total exhaustion of the energy discharged by this capacitor.
  • the return of the switch 4 to its initial position can be subject to the cessation of the phenomenon to which the triggering of the ignition is subject.
  • the phenomenon in question is the circulation of water in a pipe 16 intended to be heated by the gas of the burner 14, the pipe forming part of a water heater or of a boiler intended for central heating by circulation of water changed in radiators 17 using a pump 18.
  • Such a device has many advantages over those existing to date, in particular with regard to reliability, small size, robustness, simplicity and low price, since most of the constituent elements can be formed from electronic organs.
  • the invention is in no way limited to those of its embodiments and of application which have been more especially envisaged; on the contrary, it embraces all variants, in particular those in which the valve control device described above would equip an appliance other than a water heater, a bath heater, or a circulation boiler. 'water, device in which the valve would still be controlled, not manually, but automatically depending in particular on the exceeding of a given threshold by a predetermined parameter such as time (timer) or temperature (thermostat).
  • a predetermined parameter such as time (timer) or temperature (thermostat).
