10. a kind of automatic control current stabilization method of gas heating stove automatic control current stabilization proportioning valve, the gas heating stove automatic control current stabilization ratio
The limiting structure that there is example valve claim 1 to stop any gas heating stove automatic control current stabilization proportioning valve of claim 9, it is special
Sign is: (1) before ventilating, the valve pad of shut-off valve assemblies pushes down boss and blocks intercommunicating pore, and retaining ring blocks ratio valve chamber upper end, valve
Mouth is closed；(2) coil is powered, and static iron core absorption dynamic iron core moves outward, and valve pad and boss are detached from, combustion gas through inlet chamber, even
Through-hole, air intake duct, connection through-hole enter spacer ring, and retaining ring and ratio valve chamber upper end are detached from, and valve port is opened, and the combustion gas warp of air intake duct
Connection through-hole, adjusting concave ring, the first adjustment hole act on above epithelium, and the combustion gas of gas off-take enters adjusting cover through the second adjustment hole
Inner cavity acts below epithelium, and when acting on the setting dynamic balance of epithelium top, epithelium lower section and valve port pressure spring, valve port is in
Ideal design aperture, at this point, the pressure difference of the combustion gas of the combustion gas and gas off-take of air intake duct is that △ P=air intake duct gaseous-pressure P1- goes out
Air flue gaseous-pressure P2；(3) when air intake duct gaseous-pressure increases, the thrust acted on above epithelium increases, proportional valve spool band
Dynamic retaining ring moves downward, and valve port opening reduces, and throttling action increases, until the pressure difference of the combustion gas of the combustion gas and gas off-take of air intake duct
△ P is kept, guarantees that the gas flow of gas off-take output is constant；Conversely, being acted under epithelium when air intake duct gaseous-pressure reduces
The thrust of side increases, and proportional valve spool drives retaining ring to move upwards, and valve port opening increases, and throttling action weakens, until air intake duct
The pressure difference of combustion gas and the combustion gas of gas off-take keeps △ P, guarantees that the gas flow of gas off-take output is constant；(4) when gas off-take combustion gas
When pressure rise, the thrust acted below epithelium increases, and proportional valve spool drives retaining ring to move upwards, and valve port opening increases, section
Declines are flowed, until the pressure difference of the combustion gas of the combustion gas and gas off-take of air intake duct keeps △ P, guarantee the combustion gas stream of gas off-take output
It measures constant；Conversely, acting on the thrust decay below epithelium when gas off-take gaseous-pressure reduces, proportional valve spool drives retaining ring
It moves downward, valve port opening reduces, and throttling action increases, until the pressure difference of the combustion gas of the combustion gas and gas off-take of air intake duct keeps △
P guarantees that the gas flow of gas off-take output is constant；(5) pressure difference of the combustion gas of the combustion gas and gas off-take of air intake duct can pass through
The precompression of valve port pressure spring is adjusted to set, rotates adjusting rod, pressure regulation screw pitch can be made to move up and down dynamic, to reach regulating valve
The precompression of mouth pressure spring；(6) it according to the precompression of the valve port pressure spring of setting, adjusts depth pistion and adjusting concave ring upper end is kept to be higher than
The set distance of through-hole lower end is connected, guarantees the sensitivity of the pressure difference of the combustion gas of adjustment air intake duct and the combustion gas of gas off-take.
