Abstract
The utility model provides a burner of gas oven which can make the temperature of the oven stable, and consists of a gas intake pipe, an electromagnetic valve, a gas regulation valve, an air-supply fan, an air pipe, an ignition needle and a spread flow plate. The gas inlet of the gas regulation valve is connected with the gas outlet of the electromagnetic valve. The gas outlet of the gas regulation valve is connected with the gas inlet of the air pipe. When the pressure of the gas source changes or the furnace temperature is changed by other causes, the furnace temperature can be returned to the original setting value by adjusting the gas regulation valve in the way of the manual adjustment or the self adjusting. The burner of gas oven is suitable for all gas ovens.
Description
Technical field
The utility model belongs to the burner that plant equipment, especially fuel gas oven are used in baking.
Background technology
In the prior art, the burner of the fuel gas oven of being introduced as the ZL97211981.7 specification is made up of snorkel, combustion gas plate, baffle plate and pressure fan.Snorkel is a long tube, end sealing, and the other end connects pressure fan, is provided with air inlet on snorkel, and venthole is arranged on snorkel, and the venthole top is provided with the combustion gas plate, is fixed with baffle plate by support on the combustion gas plate, and the igniting pin is arranged on combustion gas plate top.This burner can be realized equally distributed combustion gas flame, prevents that flame is concentrated, but in this burner, combustion gas directly enters snorkel by pipeline from air inlet, when the air pressure of fuel gas source is unstable, can causes the flame intensity change and furnace temperature is changed, the effect of influence baking.
Summary of the invention
The purpose of this utility model provides a kind of fuel gas oven burner of avoiding oven temperatures to change with gas pressure.
The utility model comprises gas inlet pipe, magnetic valve, gas control valve, pressure fan, snorkel, igniting pin and diffuser plate; Snorkel links to each other with pressure fan, and gas inlet pipe links to each other with the air inlet of magnetic valve, and the air inlet of gas control valve links to each other with the gas outlet of magnetic valve, and the gas outlet of gas control valve links to each other with air inlet on the snorkel.Fresh air is sent into snorkel through pressure fan; Combustion gas enters in the snorkel through gas inlet pipe, magnetic valve, gas control valve and air inlet and mixes with fresh air.Under the effect of snorkel internal pressure, combustion mixture sprays from the venthole of snorkel both sides, and the pin mark combustion of being lighted a fire forms evenly soft flame through blocking of diffuser plate.When the rotating speed of pressure fan was certain value, the aperture of the shutter of pressure fan and the aperture of gas control valve had just determined a certain respective intensities of flame.Can make the mixture strength increasing and flame is strengthened if the pressure of the fuel gas source rising fresh air amount of sending into is constant, furnace temperature rises, thereby can recover the oven temperatures that mixture strength is kept original setting by the aperture of turning gas control valve down this moment.Vice versa.
The utility model contrasts the increase of existing fuel gas oven burner and is provided with gas control valve, and it can make flame intensity constant by regulating gas control valve under the situation that supply gas pressure changes or other factors influences of fuel gas source, has improved baking quality.
Description of drawings
Further describe the utility model below in conjunction with embodiment and accompanying drawing.
Fig. 1 is first example structure schematic diagram of the present utility model;
Fig. 2 is second example structure schematic diagram of the present utility model;
Fig. 3 is the 3rd an example structure schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, the air outlet of pressure fan 4 is connected with an end of snorkel 6, one end of gas inlet pipe 1 is connected with fuel gas source, the other end is connected on the air inlet of magnetic valve 2, the gas outlet of magnetic valve 2 is connected with the air inlet of manual gas control valve 3, and the gas outlet of manual gas control valve 3 is connected to the air inlet 5 of snorkel 6 nearly pressure fan 4 one sides; The end of snorkel 6 is a blind end, and a plurality of ventholes 8 are arranged on the tube wall of snorkel 6, and spray point 7 is installed near the venthole 8 and the metal outer wall of snorkel 6 keeps suitable arcing distance; Snorkel 6 upper fixed are equipped with diffuser plate 9.Magnetic valve 2 must be established by cable logical during work, there is combustion gas to enter snorkel 6 through magnetic valve 2 and manual gas control valve 3, pressure fan 4 gets electric rotation simultaneously, fresh air is pressed into snorkel 6 forms mist from venthole 8 ejections with combustion gas, light through spray point 7 and to catch fire, flame is formed soft flame in flakes uniformly by diffuser plate 9 guiding.When the air pressure change of fuel gas source, the concentration of mist changes thereupon, and the also corresponding change of the intensity of flame thereupon causes furnace temperature to change; Perhaps the material quantity change of carrying when the baking oven inner bag also can make furnace temperature change; Just can again recover normal furnace temperature by the aperture of the manual gas control valve 3 of manual adjustment this moment.
With reference to Fig. 2, the difference of Fig. 2 and Fig. 1 is that manual gas control valve 3 changes the gas control valve 3 of thermal expansion into, and its temperature-sensitive bag 10 is installed in the interior appropriate location of baking oven to experience furnace temperature.When changing owing to gaseous-pressure or other reason when furnace temperature is changed, the working medium bulbs of pressure in the temperature-sensitive bag 10 change, and make furnace temperature stable thereby the spool that promotes the gas control valve 3 of thermal expansion changes aperture.Thus, present embodiment 2 provides a temperature automatic regulating system.
With reference to Fig. 3, the difference of Fig. 3 and Fig. 1 is that manual gas control valve 3 changes the gas control valve 3 of electrical servo into.The gas control valve 3 of electrical servo can be according to the big or small corresponding controlling opening of valve of the electric parameters that flows to it (as voltage, electric current, pulse etc.), and it can form accurate furnace temperature regulating system with temperature sensor, control circuit.
The utility model is simple in structure, easy to use, and it can be under the situation that the fuel gas source supply gas pressure changes or other factors influences, flame intensity that remains unchanged and baking temperature, and it is suitable for use in all fuel gas ovens.
