Definitions
- the invention relates to a device for supplying gas to a gas water heater with a gas burner with flame control in the supply line to the gas burner has a valve arrangement which at Initiation of operation of the gas burner in the open position is controllable.
- valve arrangement a first solenoid valve for an amount of ignition gas and a second solenoid valve for an operating gas quantity and that the first solenoid valve with the initiation of the ignition and the second solenoid valve with the response the flame monitoring can be controlled in the open position.
- the operating mode can take place once so that with the activation of the second solenoid valve, the control of the first solenoid valve can be switched off is.
- valve arrangement is expanded so that the first A solenoid valve is assigned an adjusting device with which the amount of ignition gas can be set then the amount of pilot gas can be set so that a low-noise, Safe ignition guaranteed over all burner tubes of the gas burner is.
- the passage cross-section is made with the adjusting device the first solenoid valve changed.
- the gas supply has a chamber, which leads to the gas burner via the first and the second solenoid valve and the one controlled by the removal of water from the gas water heater Water valve gas can be supplied.
- the solenoid valves in a line section pass in which includes a manually adjustable power control valve is to reduce the released gas quantity of the valve arrangement and adjust to an intended performance.
- a further embodiment provides that the Downstream of the power valve and associated with the gas burner, an adjusting device is provided with which an exact nominal gas quantity can be set.
- the invention is based on an embodiment shown in the drawing with a section explained in more detail.
- a gas water heater e.g. Water heater
- a gas burner 50 an ignition device and a flame monitor, e.g. with an ionization electrode, are assigned and with a control circuit for commissioning of the device. This is necessary in the context of this invention not to be discussed in more detail as these facilities and their mode of operation belong to the state of the art in the various configurations.
- the conditions during the ignition process crucial, especially what is related to the supply of gas during this phase of operation.
- the z. B. can be designed as a membrane switch.
- the gas stream 11 thus becomes a Fill chamber 14 in the housing 10 of the gas supply.
- the Ignition device of the gas burner 50 is activated and a first solenoid valve 17 controlled, as the control command 21 reveals.
- the first solenoid valve 17 opens a passage 16, the cross section of which an adjusting device 20 is changeable and adjustable so that a predetermined one Ignition gas flow in the following line section 15 of the gas supply can reach and from there to the gas burner 50.
- the actuator 20 With the actuator 20, the amount of pilot gas is adjustable so that a safe ignition all burner tubes of the gas burner 50 is guaranteed.
- the flame monitor emits a signal 22 which indicates this and controls the second solenoid valve 19. So that the full gas flow 11 through the chamber 14 in the line section 15 arrive.
- the first solenoid valve 17 can remain open or also with the control of the second solenoid valve 19 are closed. Are the Passages 16 and 18 in the total cross section of the feed cross section of the Gas flow 11 equal, then an increase in the gas flow from the Chamber 15 are effected when the first solenoid valve 17 during operation, i.e. after ignition, remains activated.
- the solenoid valves 17 and 19 in the line section 14 is a Power valve 30 is provided, which is manually set to a certain power can be.
- the gas burner 50 is directly an adjusting device 40 upstream, and regardless of the tolerances of the gas nozzles an exact nominal gas quantity can be set.
