The specific embodiment:
Shown in accompanying drawing 1 to 3, the anti-backfire segmentation conversion equipment that the utility model is used for water heater comprises the gas distributing rod 6 with two or more air supply channel, be provided with the magnetic valve 7 that is electrically connected with the ignition controller (not shown) of water heater between fuel gas inlet and the main air supply channel 61, be provided with piston valve between main air supply channel 61 and time air supply channel 62, form with the connecting axle 2 of piston 5 by handle 1, piston 5 and connection handle 1, be set with a driving lever 8 on the connecting axle 2, be set with spring 4 on the connecting axle 2 between driving lever 8 and the piston 5.Be provided with a sliding rail 3 with screw inclined plane and plane with driving lever 8 corresponding positions on the gas distributing rod 6, the terminal bending of driving lever 8 forms driving lever external part 11.When driving lever 8 slided on the screw inclined plane of sliding rail 3, driving lever external part 11 contacted with sliding piece 9 on being arranged on microswitch 10.Combustion gas enters from fuel gas inlet, is opened and closed by magnetic valve 7 and piston 5 control channels, realizes sectional combustion; When driving connecting axle 2 rotations by handle 1, driving lever 8 slides along sliding rail 3; The work intersection of locus of the event trace of driving lever external part 11 and microswitch plectrum 9; Microswitch plectrum 9 makes microswitch 10 output pulse signals, is controlled the disconnection and the closure of magnetic valve 7 by ignition controller.
Shown in accompanying drawing 4 to 5, when using gas heater, main air supply channel 61 air feed burning, when needs are changed, rotate the handle 1 on the anti-backfire segmentation conversion equipment, connecting axle 2 rotates thereupon, and driving lever 8 slides along sliding rail 3, drive piston 5 and move the air supply channel that changes gas distributing rod 6, time air supply channel 62 is opened; In this process, driving lever external part 11 touches the microswitch plectrum 9 on next door, microswitch 10 turn-off current loops, and water heater magnetic valve 7 cuts out, and blocks the supply of combustion gas, and burner is flame-out; After driving lever external part 11 leaves microswitch plectrum 9, microswitch 10 is communicated with, the current loop closure, the igniting needle-discharging, magnetic valve 7 is opened again, again air feed, burner catches fire again, at this moment, inferior air supply channel 62 and main air supply channel 61 are so just realized the conversion of sectional combustion all to the burner air feed.The key of this segmentation conversion equipment is to stop air feed in transfer process earlier, treat flame-out after air feed igniting again, thereby avoided in transfer process, producing the instantaneous variation of gaseous-pressure and caused tempering phenomenon.Shown in accompanying drawing 6,7, just in time opposite with said process for the duty exploded view of segmentation conversion equipment by the fiery at least row of many fire rows conversion, when the many fire rows of gas supply were burnt, driving lever external part 11 did not contact with plectrum 9, and the current loop of magnetic valve 7 is communicated with; When clockwise rotating handle 1, driving lever external part 11 contacts with plectrum 9, and the current loop of magnetic valve 7 disconnects, and burner stops air feed; When driving lever external part 11 left plectrum 9, the current loop of magnetic valve 7 was communicated with again, the few fire row of gas supply burning.Because segmentation conversion equipment of the present utility model stops air feed earlier in transfer process, air feed igniting again after waiting to stop working, avoided in transfer process, producing the instantaneous variation of gaseous-pressure and causing tempering phenomenon, particularly effective for the water heater of use natural gas or artificial coal gas.
