1.the thermocouple : thermocouple is a pair ( two ) different materials welded together alloy wire , when the thermocouple heated at one end , the other end of the cooling, the alloy wire can be generated between the two electromotive force ( voltage ) of the alloy wire . Generating an electromotive force determines the size of the material properties of the alloy wire and the heating temperature . It consists of a metal wire, protective sleeve , and transmission line components. The flame heating , the thermocouple to generate an electromotive force across the solenoid valve , the solenoid valve is energized to maintain pull, maintaining the gas conduction; When an accident flame , the use of the electromotive force of the thermocouple at both ends disappears energized solenoid release , blocking the gas passage , to prevent gas spills .
2.the solenoid valve : is a U-shaped iron punching Diecheng or U-shaped ferrite core columns as ( armature ) of the electromagnet . It has energized the magnetic field generated spool can pull rod, the gas intake valve opens , loss of power on its own after a spring force can automatically reset , shut the gas vent, ensure the gas will not spill . Gas stove ignition knob is pressed , the first by the valve body thimble top open solenoid valve, when the burning is normal, thermocouple electromotive force generated at both ends ( voltage ) , the solenoid valve is energized to maintain pull, release the hand after ensuring gas conduction ; when an accident flameout , the thermocouple electromotive force produced no fire without , solenoid valves release the gas path seal , to ensure the safety of use .
3.the valve assembly : gas stove thermocouple and valve assembly is mainly used for gas gas gas gas flow control and regulation . By the valve body , valve core , ejector pipe, knob lever positioning device , transmission and switching between functions needed accessories. Gas valve for regulating the gas flow , the control apparatus of the gas path , it is because the gas vent valve and the valve body is provided between the inlet angle , when the lever is not pressed to rotate the knob , the air vent valve is not aligned with the inlet , the gas path is still sealed ; if at this time the ignition is successful, the rotary knob , gas conduction, gas will be lit ; if the ignition is not successful , the knob does not rotate, can prevent the gas leak ; gas valve on the diameter of the pores of different gas flow limiting , controlling gas stove flame size. Positioning device by positioning blocks and valve body positioning groove composition, "off" state, the positioning block sets in the positioning groove, can not turn the knob , press and turn the knob, the positioning block starting rotation , from the positioning limits to ensure that the loose after opening the hand knob within a certain range can be freely rotated to adjust the fire size.
