Definitions

  • the invention relates to a gas control valve for a gas heating furnace or the like 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 are used for ignition and for the control or regulation of a gas flow flowing to a burner.
  • a gas control fitting described which is intended for the preferred installation in a gas-fired stove or the like. It enables the operation and monitoring of the burner.
  • the burner is divided into a pilot burner and a main burner.
  • the gas control valve has a start-up with ignition protection and reclosing lock and a control unit for the gas flowing to the main burner gas.
  • a manual ignition of the gas stream flowing to the pilot burner takes place via a piezoelectric ignition element associated with the start-up.
  • This gas control valve also has a commissioning with ignition protection and a control unit for the amount of gas flowing to the main burner.
  • a control unit for the amount of gas flowing to the main burner.
  • an electronic control unit for control and ignition is used in this gas control valve, however, an electronic control unit.
  • the ignition of the gas stream flowing to the pilot burner is possible via a piezoelectric ignition element.
  • thermoelectric Zündschsventil a main valve, which serve both for Zündtechnisch as well as for splitting the gas stream into shares for a main burner and a pilot burner, with a main valve downstream control unit for the gas flowing to the main burner gas stream and with other, secondary Functional elements known, wherein the gas control valve has a sensor through which the operating state of the main burner is detected.
  • the invention is based on the problem to provide a gas control valve, which also transfers the pilot burner in the "off” position after the startup of the gas stove at "off" position of the main burner to keep the energy consumption of the gas heater as low as possible. Furthermore, the gas control valve should have the simplest possible structure.
  • the problem is solved in that the gas control valve has a sensor, via which the operating state of the main burner can be detected.
  • the sensor is connected to the thermoelectric Zünd Anlagensventil that when changing the operating state of the main burner of the position "on” in the "off” position by a signal emitted by the sensor, the thermoelectric Zünd Anlagensventil assumes its closed position.
  • a delay element is arranged between the sensor and the thermoelectric ignition safety valve.
  • the sensor may for example consist of a flow sensor, which detects the operating state of the main burner in that it is checked whether a gas flow to the main burner flows.
  • the senor consists of a temperature sensor which detects the operating state of the main burner above the temperature present at the main burner.
  • Another possibility is to go with a sensor directly to the control unit for the gas flowing to the main burner gas quantity, so as to detect the operating state of the main burner.
  • the gas control valve according to the invention will be explained in more detail below using an exemplary embodiment.
  • the embodiment shows a schematic representation of an embodiment of a gas control valve in a sectional view in the open position.
  • the exemplary gas control valve according to the invention shown in the figure is a switching and control device, which is preferably intended for installation in a gas heating furnace 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 32 and a main burner 33rd
  • the 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. Escaping in extension of the actuating rod 10, the partition wall 15 has a first opening 16, which forms a main valve 35 together with a valve disc 36 located on the actuating rod 10 on the one hand and on the other hand belongs to an ignition safety valve 17. Between the Zündtechnischsventil 17 and the main valve 35 is located within the opening 16th the Zündgasausgang 3.
  • the Zündtechnischsventil 17 is influenced by a gas-tight in a bearing of the housing 1 thermoelectric Zündtechnischsmagneten 18, which is located downstream of the gas inlet 2.
  • thermoelectric Zündschsmagnet 18 acts on an armature 19 which is rigidly connected to a valve rod 20 on which the valve plate 21 of the Zünd Anlagensventils 17 is attached. About the electronic control unit 5, as well as via a pilot flame exposed thermocouple 22 of the thermoelectric Zünd Anlagensmagnet 18 can be excited.
  • the control unit 8 In the flow direction behind the commissioning 7 is located within the housing 1 to the control unit 8 associated switch 24.
  • the switch 24 is designed in a known manner so that a modulating control of the valve 25 with sudden switching on and off in the partial load range via the valve 26th is effected.
  • the partial load flow is limited by the cross section of the opening 27 located in the partition wall.
  • a temperature sensor 34 in this example, an NTC - resistance temperature sensor is mounted, which is electrically connected to the electronic control unit 5, which in turn already has a connection for controlling the Zündtechnischsmagneten 18 of the thermoelectric Zündtechnischsventils 17.
  • a time delay element is interposed in the electronic control unit 5.
  • thermoelectric ignition lock valve 17 is closed.
  • the closing of the thermoelectric Zünd Anlagensventils 17 not immediately, but with a time delay to re-ignite the Zündbrenners 32 and at a short-term necessary reignition of the main burner 33, as may occur in particular at room temperature controls thus avoiding additional stress on the ignition device.
  • the gas control valve for example, even more functional units, such as a pressure regulator or the like, except those mentioned may have. Also, the query of the prevailing at the temperature sensor 34 temperature not running, but at certain intervals and / or only take place when an actuation of the drive unit 31 has taken place.
  • thermoelectric ignition safety valve 17 can take place, for example if an electronic control unit 5 is not present.
