Working principle of the present invention is: generally, and gas burning system or be rock gas, or be liquid gas; Because pressure and the calorific value of different combustion gas are all different, so will reach in the situation of same power, the size of the needed nozzle of different combustion gas is different, so need artificial going to change nozzle; This valve can directly should be in gas system with double gas sources.It can be according to the difference of source of the gas and thereby double-air-supply nozzle is adjusted to different states is adapted to different fuel gas sources automatically.And need not be artificial go again regulate source of the gas and change nozzle; By epithelium 11, regulated, when gaseous-pressure is greater than the pressure that epithelium 11 upsprings, epithelium 11 is upspring, driving pressure regulation bolt 12 moves upward, pressure regulation bolt 12 contacts with seal ring 11, and now second channel 18 and third channel 17 are obstructed, and combustion gas can only enter spool from first passage 8, enter the first nozzle 2 by the 7th passage 25 and Five-channel 23 again; When gaseous-pressure is less than the pressure that epithelium 11 upsprings, epithelium 11 is failure to actuate, now second channel 18 and third channel 17 communicate, combustion gas enters respectively spool 4 from first passage 8 and four-way 16 respectively, enter nozzle 2 and nozzle 1 by the 7th passage 25 and Five-channel 23, the 6th passage 24 and the 8th passage 26 respectively again, as shown in Figures 7 and 8.When access be the combustion gas of relatively low pressure the time, thereby the underpressure of combustion gas is raised pressure regulation bolt 12 so that epithelium is upspring, so, when controlling valve rod in little fire screen or large fire screen, in the interior outer nozzle that combustion gas enters respectively double-air-supply nozzle by two passages, spray, flow is larger.When access be the combustion gas of relatively high pressure the time, thereby the pressure of combustion gas is enough to make epithelium 11 to be upspring raises the pressure regulation bolt, pressure regulation bolt 12 contacts with seal ring 10, produce seal action, when controlling valve rod 7 in little fire screen or large fire screen, in the inner nozzle that combustion gas enters double-air-supply nozzle by a passage, spray, flow is less, as shown in Figures 9 to 11.
Ignition principle: inside valve push rod is rotary valve rod 7 simultaneously, and push rod 4-3 is backed down by valve rod 7, now, push rod 4-3 and valve body 4 coupling places are backed down, and seal ring 10 no longer seals, and combustion gas enters ignition channel 21 from breast door 4-15, reentrant point fire-fighting mouth 22, the inlet point fire tube 20 afterwards; Piezoelectric ignition device 5, in the drive lower piezoelectric igniting of valve rod 7, is lighted combustion gas, as shown in figure 12.
