Abstract

The utility model introduces a sectional-type fire light inflamer device of a gas water heating apparatus with gas paths of two inflamer devices (summer) used for lighting fire and gas paths of other inflamer devices respectively controlled by two valves on the basis of a four-season type gas water heating device. The gas paths valves used to control other inflamer devices are opened and the other inflamer devices are lighted after the gas paths valves of inflamer devices used to control fire light are opened and the fire light inflamer devices are lighted. The utility model improves the safety of the water heating device, and overcomes some shortcomings of the conventional water heating devices and has the advantages of simple structure, low cost, and high reliability.

Description

Water heater multistage ignition formula combustion mechanism

Technical field

The utility model is a kind of water heater multistage ignition formula combustion mechanism.

Background technology

The sparking mode of gas heater is divided into two kinds: a kind of for directly putting big fire, another kind of is that point is ignited earlier, lights big fire by igniting.Directly the advantage of some big fire is simple in structure, has saved pilot flame burner, and shortcoming is to be easy to generate detonation.The advantage of lighting big fire by igniting is to be not easy to produce detonation, and shortcoming is a complex structure, many pilot flame burners.

Summary of the invention

In view of the shortcoming that existing water heater exists, the utility model has designed a kind of multistage ignition four seasons type water heater, and it is to put two burners earlier, other burners could be lighted after two burners are lighted, have simple in structurely, be not easy to produce detonation, the characteristics that security is good.

Gas heater segmented ignition mechanism mainly is made up of several like this parts: ignition controller, air valve body, battery, Water operated switch gear, self-priming valve A, self-priming valve B, the tracheae of band four seasons type gas control valve, burner assembly (burner, support pipe etc.), spray point, compositions such as inductive needle.Put wherein two burners when this combustion mechanism difference is igniting earlier, these two burners are lighted back other burner air valves of control and just can be opened, and other burners just can be lighted.And two burner combustion are to be in burning at full capacity, have overcome the problem of bad igniting again.Have only two burners giving vent to anger during igniting, improved the security of water heater, the tracheae of this combustion mechanism is divided into three sections, form four groups of fire with burner, be respectively two burners (summer), six burners (autumn), eight burners (spring), 12 burners (winter) are regulated control valve and can be produced adaptation spring, summer, autumn, different outputs of winter, have thoroughly solved the too high problem of big flow water heater water temperature in summer.Two burners that are used for summer also play the effect of start-up burner simultaneously.Control valve adopts ceramic valve plate, and is durable in use, cost is low, characteristic of simple structure.

Description of drawings

Fig. 1 is the schematic diagram of multistage ignition combustion mechanism.Mark among the figure: 1, ignition controller, 2, air valve body, 3, battery, 4, Water operated switch gear, 5, self-priming valve A, 6, self-priming valve B, 7, the tracheae of band four seasons type gas control valve, 8, burner assembly, 9, self-priming valve C, 10, start-up burner, 11, inductive needle, 12, spray point.Sweep among the figure is represented the connecting line between several parts.

Fig. 2 is the profile of tracheae part in the tracheae of band four seasons type control valve.Mark among the figure: 15, one section on the left side of tracheae (four nozzles), 13, middle one section (two nozzles), 14, one section on the right (six nozzles).

The specific embodiment

As depicted in figs. 1 and 2, the multistage ignition combustion mechanism comprises ignition controller 1, air valve body 2, battery 3, Water operated switch gear 4, self-priming valve A5, self-priming valve B6, the tracheae 7 of band four seasons type gas control valve, burner assembly 8, self-priming valve C9, start-up burner 10, inductive needle 11 and spray point 12, wherein be divided into three sections with the tracheae in the tracheae 7 of four seasons type control valve, comprise one section on the left side (four nozzles) 15, middle one section (two nozzle) 13 and one section on the right (six nozzles), three sections air supply channel is independently, the air supply channel of two nozzles is controlled by self-priming valve A, the air supply channel of four nozzles and six nozzles is controlled by self-priming valve B, two these sections of nozzle are formed start-up burner with burner, and it is in two sections centre.

During water heater working, current are through Water operated switch gear, switch opens, battery and ignition controller are connected, ignition controller work, ignition controller control self-priming valve A and self-priming valve C open, spray point discharge simultaneously, light two burners, flame burns inductive needle, because conducting flame, inductive needle and burner form path, ignition controller control self-priming valve B opens, and other burners are lighted.The adjusting control valve can be controlled the tolerance size of left and right sides nozzle and have or not, thereby realizes being suitable for four groups of fire of spring, summer, autumn, different temperature of winter, and fiery big I is regulated arbitrarily, produces the hot water that is suitable for spring, summer, autumn, different temperature of winter.Because have only two burners that gas is arranged during igniting, other ten burners do not have gas, gas output is few, is not easy detonation during igniting, has improved the security of water heater.

Claims

1, a kind of water heater multistage ignition formula combustion mechanism, this combustion mechanism mainly is made up of several like this parts: start-up burner, air valve body, battery, Water operated switch gear, self-priming valve A, self-priming valve B, self-priming valve C, the tracheae of band four seasons type gas control valve, burner assembly, spray point, compositions such as inductive needle, it is characterized in that being divided into three sections with the tracheae inside in the tracheae of four seasons type gas control valve, four combustor air inlets of the one section confession in the left side, two combustor air inlets of middle one section confession, six combustor air inlets of the one section confession in the right, middle two burners are used for igniting, its air inlet is by self-priming valve A and self-priming valve C control, and the air inlet of remaining burner is controlled by self-priming valve B.
