Abstract

The utility model discloses an automatic conversion burner of a stove using liquid fuel. The left side of a liquid multifunction converter is provided with a cone valve switch; a drive rod of the switch is provided with a valve rod of a control valve which is positioned at the right side by push and press; controllable liquid fuel can flow into a precombustion chamber. The inflow and the flow quantity of liquid fuel between the liquid multifunction converter and an automatic conversion gasifier can be controlled by an automatic switch which is controlled by bimetallic elements. Liquefied gas after gasified can enter a mix combustion chamber and a combustion chamber by a gas knob positioning adjustment switch, and a fire division cover can obtain stable combustion flame. Methanol and fusel oil fuels can automatically convert to gas combustion by the utility model. The automatic conversion burner of a stove using liquid fuel has no coking and is safe.

Description

Automatically change burner

The utility model relates to a kind of automatic conversion burner that uses the stove and accessory of liquid fuel.

Have only the minority resident to use piped gas or natural gas in China, most of resident is a fuel with coal, faggot still, its dust polluting environment.Gasoline or liquefied gas price are more expensive, and the methyl alcohol or the fusel oil and other industrial byproducts output that are provided by industrial production are very abundant, and domestic many producers have manufactured and designed multiple stove and accessory for them.But these stove and accessorys have following point: because before liquid fuel enters the combustion chamber, need the preheating gasification, and temperature instability before present stove and accessory liquid fuel within enters and burns, when temperature was hanged down, liquid fuel still can't burn and pollute the environment for liquid state; Temperature is too high, and the stove and accessory part is oxidized, produces the knot charcoal, the parts that cause line clogging often to clear up or more to renew.The degree of present stove and accessory liquid fuel gasification relies on the user to estimate, thus be not gasified totally and when delivering to burner in a large number when liquid fuel, but fire hazard, this is a danger close, so the user needs often looking after of carefulness in using.In addition liquid fuel being delivered to gasifier and burner is to rely on frequent use inflator to guarantee what certain pressure was realized, and both inconvenience also was difficult for keep-uping pressure stable.

The purpose of this utility model is to have designed by pressure-reducing valve, bimetallic element, automatic switch, the multi-functional automatic switch of liquid for overcoming above-mentioned weak point, change the automatic conversion burner that main parts such as gasifier, burner and gas knob location by-pass cock are formed automatically.Open gas knob location by-pass cock and just can change burning automatically, regulate liquid gasification and air demand automatically, combustion flame is stable.

The utility model content: the left side of liquid multifunction converter is provided with the Cone valve switch, this switch is made up of Cone valve, drive rod and the knob of band radial direction through hole, the three connects as one, the position of the radial direction through hole of Cone valve is corresponding with the transfusion pore of liquid multifunction converter, the depression bar that can push the control valve valve rod is housed on the drive rod, this control valve is positioned at the right of liquid multifunction converter, and its input port communicates with the transfusion pore, and its liquid outlet communicates with precombustion chamber through pipeline; Automatic switch is connected in the transfusion pore of liquid multifunction converter and changes automatically between the liquid input tube road of gasifier, and the clutch drive rod that the control automatic switch opens and closes is located at the bimetallic element lower end; The one side that is bent into the bimetallic element of square is fixed on the top of automatic conversion gasifier, and another side hangs from above in the side of changing gasifier automatically, and its lower end is provided with the clutch drive rod; Automatically the cylindrical shape vaporizer of conversion gasifier is positioned in the middle of the combustion chamber, with the burner arranged concentric, be connected through the liquid input tube road between the vaporizer of the multi-functional automatic switch of liquid and automatic conversion gasifier, vaporizer also is provided with the output liquefaction tracheae that flows to gas knob location by-pass cock, burner is the double-walled cylindrical structure, the Fen Huogai of gas combustion is equipped with at its top, and burner inner wall is provided with the heating fire seperating hole of conversion gasifier automatically; Be provided with the pressure-reducing valve that makes liquid fuel pressure stable between the angle valve switch of liquid fuel within basin and the connecting line of the multi-functional automatic switch of liquid.

The utility model advantage, (1) user only need open gas knob location by-pass cock just can change burning automatically; Utilize bimetallic element can regulate liquid gasification and quantity delivered automatically.(2) the cold-peace superheating phenomenon can not take place in the utility model combustion process, thus both free from environmental pollution, can not produce the knot charcoal yet, significantly reduce frequent repairing or changed the pipeline part.(3) the multi-functional automatic switch of liquid stops feed automatically when burner flame extinguishes, so safe in utilization.(4) establish pressure-reducing valve at the pipe way of angle valve switch and the multi-functional automatic switch of liquid, certain through the liquid fuel pressure of pressure-reducing valve output, so flameholding does not need to inflate frequently pressurization yet.
