As shown in Figs. 1-2, combustion gas enters manual valve body by air inlet pipe 81, through a thermocouple flameout protection electromagnetic valve device 3, combustion gas is closed in Electromgnetic seat valve plug 13, in the drive shaft that blowout protection relief valve port downstream, tool one are driven by knob 92, one is driven the pressing of moving axis 92 and can open the driving lever 15 of the safe valve plug 13 of blowout protection, one be driven the rotation of moving axis 92 and The driving cam 91 of drive, an adjusting lever 42 abut the driving cam 91 when normal, one is driven by the arm of force 46 for adjusting lever 42 And the main valve plug 21 being opened, a main valve stem 23 in the fixed main valve plug 21 of suitable position, one end set a pulling fixed ring 25 by Adjust the pulling of lever 42, and it is normal with a main valve plug spring 24 when press the pulling fixed ring 25 and main valve plug 21, in the master Fastening sets a positive taper current limiter 222 at the downstream of valve plug 21, and later and extension rod is to the first outlet oral cavity 85, in extension One is suitably located at again fixed one reversed taper current limiter 22 on bar, thus structure and be formed in not using before the hand-operated valve, the hand The channel that there is dynamic valve twice valve port to close combustion gas.

Referring again to Fig. 3-4, when user presses and rotates knob, the pressure driving lever 15 of drive shaft 92 will drive, Mandril 16 is opened, the valve opening with moving electromagnetic valve safety valve plug, drive shaft 92 is rotated to 90 degree of most high fire ignition location simultaneously, Band moving cam 91, and so that adjusting lever 42 is pulled on fixed ring 25 by the promotion of cam 91 and is pulled open, and keep main valve plug 21 same Shi Kaiqi, combustion gas enter the first outlet oral cavity 85 via flameout protection electromagnetic valve mouth to primary valve, are opened to burner by fine motion The firing pulse high tension spark for closing 93 circuit conducting is lighted.In the case, if user clockwise reversion knob Positive taper current limiter can be made close toward valve port, and then the flow of valve port is made to become smaller, until close to close port mouth, flowed to The combustion gas in the first outlet oral cavity can become gradually small, otherwise become larger valve port if user's counter-clockwise direction is toward 90 degree of rotations, Flow also changes from small to big.

Referring again to Fig. 5-8, when user again from 90 degree of positions again toward 130 degree of position turning knobs when, at this time reversed Taper current limiter 22 just begins to approach valve port, flow to the flow in the first outlet oral cavity 85, and therefore reversed taper current limiter 22 Effect starts again by slowly becoming smaller greatly, when about going to 170 degree of positions, this reversed taper current limiter 22 it is completely enclosed live this When one gas outlet valve port 102, referring again to Fig. 9-10, the flow in the first outlet oral cavity 85 is led in combustion gas at this time, only remaining shell Upper one gives and stays adjustable by-pass prot, to guarantee the minimum discharge combustion gas that will not all allow stove fire to extinguish during adjusting.

Referring again to Figure 11-12, to illustrate that the utility model creates the optimal use state of another embodiment, in response in general Formula cooking, need have in, two kinds of burners of outer ring carry out the dual function that should be simmered with outer ring high fire quick-fried and only inner ring small fire, The utility model is created in the downstream of the main valve plug 21 other than the first outlet oral cavity 85 being set, then is added one second and gone out Port 84 arrives outer annular burner, and the middle section position in the outlet oral cavity sets one second gas outlet valve 28, and in the extension Bar on reversed taper current limiter 22 tail end appropriate position, then connect one and can be pushed up by valve plug reset spring 27 and hold and can live The second gas outlet valve plug 26 of dynamic displacement a small distance, when driving cam adjusts lever and main valve in pulling open for different angles The aperture of plug second stage from large to small during, combustion gas at this time it is average be supplied to port 85 and at first The phenomenon small with Datong District is presented in the flow of two gas outlets 84, two outlets.

Referring again to Figure 13-14, this second gas outlet valve plug 26 can be first allowed first to be closed until rotating between knob again inverse time When the second gas outlet valve port 28, situation at this time is that combustion gas is only supplied to the first gas outlet 85, and there is no combustions for the second gas outlet Gas, if user is further continued for reversely adjusting, can allow third to go out again so that maximum fire is presented in the combustion gas of the first gas outlet again Under the combustion gas of mouth slowly becomes again.

It, can be anti-again if the firepower for the first outlet chamber (inner ring) that user still feels is still too big referring again to Figure 15-16 Clockwise rotates knob, and the reversed taper current limiter can reduce the flow via valve port 102 again at this time, although valve plug 26 at this time The second gas outlet valve 28 is sealed, but bar continues bar toward left position again toward that can compress valve plug subsequent spring 27 when left dislocation It moves, when current-limiting apparatus closes the second gas outlet valve port 28, only stays on shell a minimum discharge for giving the by-pass prot 83 set The first outlet oral cavity (inner ring outlet) 84 is flowed to, using the special cooking needs of minimum firepower to stew as long-time anneal！

The above is only the preferred embodiment of the present invention, is not intended to restrict the invention, all in essence of the invention In mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
