Abstract
A temper-proof burner in which mixed gas is used comprises a main body 10, a or a plurality of fire heads 20 are installed at the outlet portion of a gas channel of the main body, a back-fire relief sheet 30 for preventing temper is arranged between each fire head and the gas channel, and an adjustable valve 40 for adjusting gas quantity is arranged in the main body. In the utility model, the burner and the adjusting valve are arranged as an integrated body, and a temper-proof structure and a sealing structure are also arranged. The utility model has the advantages of compact structure, excellent back-fire relief and seal effects and the like.
Description
Technical field
The utility model relates to a kind of air mixture burner, particularly relates to a kind of being more suitable in the air mixture that the hydrogen-oxygen air mixture is used anti-backfire burner.
Background technology
At present, multiple fuel gas has been widely used in industrial production and the people's life as coal gas, natural gas, liquefied petroleum gas, hydrogen and oxygen mixture etc.Because the combustibility of fuel gas, thereby its safety in utilization also had higher requirement.Hydrogen and oxygen mixture is a kind of new energy, when it uses as combustion gas, all will burn by burner.The duration and degree of heating and the control valve of existing burner are split-type structural, install and use inconvenience, and the sealing property of control valve are relatively poor.The more important thing is that have burner now owing to do not install fire retardant device additional at the duration and degree of heating place, thereby can not stop the duration and degree of heating tempering, the duration and degree of heating tempering then can cause the generation of accidents such as exploding.
Summary of the invention
The utility model is intended to overcome the defective of existing air mixture with burner, and provides a kind of burner and control valve integrated, and is provided with anti-backfire and hermetically-sealed construction, and is simple and compact for structure, the air mixture of back-fire relief and good sealing effect anti-backfire burner.
For achieving the above object, the utility model provides a kind of air mixture anti-backfire burner, this burner has a main body 10, in the blast tube exit of main body one or more duration and degree of heatings 20 are housed, anti-backfire is housed with fire retarding sheet 30 between each duration and degree of heating and the blast tube, also is equipped with in the main body and is used to regulate the control valve 40 that gas quantity is used.
Good effect of the present utility model is, at first, it efficiently solves the safe handling problem of burner, owing to be provided with the flame-resistant sheet of microcellular structure between duration and degree of heating and gas passage, its good flame retardancy can effectively prevent tempering, stops because tempering causes security incidents such as blast; Secondly, because burner and control valve are made as one, and be provided with hermetically-sealed construction, thereby simple and compact structure, good sealing effect, installation and adjusting are all very easy.The utility model also can be arranged to single flame head or many duration and degree of heatings form, is applicable to multiple use occasion.
Description of drawings
Fig. 1 is the utility model structure cutaway view.
The specific embodiment
Consult Fig. 1, air mixture of the present utility model has a cylindrical metal main body 10 with the anti-backfire burner, have mixed gas passage 11, duration and degree of heating installing hole 12 and control valve installing hole 13 on the main body, in the duration and degree of heating installing hole 12 in the blast tube exit of main body, be screwed metal duration and degree of heating 20, be provided with a plurality of pores 21 on the height of anger, what of duration and degree of heating come to determine as required, can be single, also can be a plurality of, a plurality of duration and degree of heatings can be connected on the blast tube.Anti-backfire fire retarding sheet 30 is housed between each duration and degree of heating and the blast tube, and this fire retarding sheet is formed by metallic grit die casting, forms microcellular structure, makes gas to pass through, and the tempering at duration and degree of heating place is then stopped by it.Each duration and degree of heating in the main body all is equipped with a control valve 40, and this control valve is a rhabodoid, and its front end places in the blast tube, the end of its taper withstands on the shape mouth place, rank of passage, the intermediate portion is threaded with main body, and its other end is then fixing by nut 50, and nut is threaded with main body.In the regulating tank of its outer end, rotate the quantity delivered of control valve adjustable fuel gas with screwdriver.Sealing gasket 60 is housed between each nut and control valve, and the sealing pad is made by graphite or fluorubber material, has good sealing property and heat-resisting quantity.
This burner can be connected on the hydrogen and oxygen mixture gas pipeline with pipe joint or alternate manner.
