In our daily life can be used almost every day, gas stove and ultimately, the application of the thermocouple , thermocouple gas stove in use and its detailed control of what we are here for everyone to talk about . In fact, the thermocouple is with the intake solenoid valve to control the switch , according to the induction principle thermocouple , is the use of current to control the intake valves . Current generation has a relationship with the structure of the thermocouple , the thermocouple is made of two different materials and protective tube of a metal material , the composition of the hot electrode , when there are two different metal alloy wire consisting of a temperature difference between the ends it will generate electricity , but the thermocouple measurement accuracy must be guaranteed in order to end the thermocouple cooling , which is why there are cold- junction compensation argument, when one end of the other end of the heating cooling , the resulting current is applied to the electromagnetic valve driven intake valve remains open when the flame goes out , the current disappears , intake valve closes , which is the use of gas stove thermocouple manufacturing principles .
        Ion Sensor: Burner with plasma needle , fire cover the flame jet has positive and negative ions , the needle is formed by the ion current, the current acting on the solenoid valve to keep the inlet valve open, when the flame goes out , the current disappears , the inlet valve Close .
       Solenoid valve: is a U-shaped iron punching Diecheng or U-shaped ferrite core columns as ( armature ) of the electromagnet .
       Gas stove in the solenoid valve is energized ( voltage current generated by the thermocouple support ) after the magnetic field generation , gas spool can pull rod , so that the intake valve opens after a loss of power on its own and under the action of spring force can automatically reset , shut the gas hole , ensuring gas does not leak .
