Pulse ignition , piezo ignition gas stove construction works and parts
First, the principle of pulse ignition gas stove ( with thermocouples , no thermocouple )
Open the gas valve , press the knob , the knob lever moves down , pushing the valve body moves down along the thimble , thimble pushes the valve body curved rod pendulum, push solenoid valve opens ; Meanwhile , knobs metal rod with pulse ignition switch line in contact with the surface shell through the formation of the knob lever ground loops, pulse starts the ignition ; due knob rod tip is flat keys , set in the gas valve keyway , if the knob counter-clockwise ( clockwise rotation by the valve body positioning device constraints, can not move ) , the positioning of the knob stopper rod tip will follow the spin- ladder play table, out of body positioning limits , the gas valve will rotate together with the rotary knob , air vent valve and valve inlet aligned conduction. At this point the gas pipeline will pass through holes valve solenoid valve gas valve nozzle ejector tube ( once mixed with air ) Burner throttle fire cover ( mixed with secondary air ) , the case after the fire burning. Ejector phase at the burner tube and the adjustment of air into the gas devices ( commonly known as the throttle ) , by adjusting the damper size ( change the air flow cross-section ) can change the primary air mixing coefficients , affecting flame condition and prevent yellow flame produces .
Since the beginning of combustion, heat the thermocouple electromotive force is generated , the solenoid valve via a wire into a coil , generating a magnetic field to pull the solenoid valve , thus maintaining the valve open state, release the hand size of the flame can be adjusted . When an accident flameout , the thermocouple leads the voltage quickly becomes zero , the solenoid valve coil de-energized , the spring action, rapidly cut off the gas passage , to prevent gas spills . To turn off the gas stove , you can turn the knob clockwise to the "OFF " position can, at this time , gas valve and solenoid valves has cut off the gas path , combustion stops , gas does not spill ; knob lever positioning maneuver into position stopper groove , the knob can not be rotated .
Second, the pulse gas stove parts of the structure :
1 , the thermocouple is a pair ( two ) different materials welded together alloy wire , when 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 : mainly used for gas gas gas gas flow control and regulation . By the valve body , the gas valve , the ejector tube , the knob lever , the positioning means , the transmission device and the accessories required to achieve functional composition of the gas conversion valve for regulating the gas flow , the control apparatus of the gas path , it is because gas valve body and the valve hole 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 the ignition point successful, then rotate the knob , gas conduction, the gas will be ignited ; if the ignition is not successful, the knob does not rotate , you can prevent the gas leak ; gas valve on the diameter of the pores of different gas flow limiting , controlling gas stove the size of the flame . Positioning means is a positioning block and the positioning groove formed inside the valve body , "off" state , the positioning block is set in the positioning groove
, The knob can not rotate , press and turn the knob, the positioning block starting rotation , from the positioning limits to ensure that the release after the hand knob within a certain range can be freely rotated to adjust the fire size.
4, the pulse ignition device: It is composed of electronic components consisting of a high-frequency oscillator pulses generated by the oscillator voltage by the high-frequency step-up transformer rise into the high voltage of 15KV , for point discharge , ignited by a spark discharge gas burner . This igniter is high , continuous discharge . Press the knob , pulse ignition start ignition ; loosen the knob , pulse stops firing .
Third, the piezoelectric ceramic gas stove works narrative
Open the gas valve , press the knob , the knob lever pressing the gas valve within the valve tip thimble moves down , pushing the gas valve inside the fire tube valve to open. As for the flat top knob lever key , set in the gas valve keyway , press the knob ( clockwise rotation by the valve body positioning device constraints, can not rotate ) knob positioning stopper rod tip will follow the spin- ladder play table , the positioning of the valve body from the restriction ; rotates counterclockwise , the gas valve will rotate together with the rotary knob , fork on the plug to drive the gas swinging fork promote ignition moves the hammer , the hammer spring is reset compression, when the knob is rotated to 90 �, the fork from the hammer , the spring force of the hammer quickly reset , hit piezoelectric ceramic cathode , at the other end ( anode ) to generate instantaneous pressure (15KV), via wire connection to fire tube discharge ignition . In turn the knob , electric ignition pin electrical fire at the same time , the gas inlet valve spool holes aligned with conduction , gas will pass two exporting its way through holes for the pipeline gas valve spool fire tube valve body jet ejector nozzle tube ( air mixing ) fire tube , fire burning, the fire cover spray .
Another way valve hole pipeline gas valve nozzle ejector pipe stove damper ( once mixed with air ) sub firearms ( mixed with secondary air ) gas conduction, after a fire burning . Ejector phase at the burner tube and the adjustment of air into the gas devices ( commonly known as the throttle ) , by adjusting the damper size ( change the air flow cross-section ) can change the primary air mixing coefficients , affecting flame condition and prevent yellow flame produces . Turn off the gas stove , simply turn the knob to the "OFF " button , then the gas valve shut the gas air intake, combustion stops , gas does not spill ;
Knob lever positioning maneuver into position stopper groove knob can not be rotated .
