Abstract
The utility model provides a semi-butterfly type no-damping and adjustable flame apparatus used for the fuel burning nozzle, which is composed of a wind cover shell, a fuel tube, primary and secondary wind separating frames, a primary wind whirl plate and an air inlet pipe which is arranged on the top of the wind cover shell. The top ends of circular plate part of the primary and the secondary wind separating frames are in a horizontal shape, and the primary and the secondary wind separating frames are movably connected with a semi-butterfly type air regulating board through a shaft. One end of the shaft penetrates through the pipe wall of the air inlet pipe to be connected with an adjuster. The utility model has the advantages of simple structure, adjustable flame length and convenient operation, and is suitable for various oil and gas burner tips. When regulated to the air quantity of 90 DEG, the utility model can realize no-damping operation. The utility model can implement remote regulation through an actuating mechanism of the butterfly valve.
Description
The utility model belongs to the fuel nozzle technology, relates in particular to the louver of burner.
Present normally used burner louver is spiral-flow type and bushing type, and air strand is mixed with eddy flow form and direct current form and fuel stream respectively, produces long and flame weak point.The way that in the past was used for regulating at random a secondary wind is that each burner is joined two air supply lines, realizes the adjusting at random of a secondary wind by regulating two valve locations on the pipeline respectively, to reach the purpose of regulating the length of flame.The weak point of this way is the complicated of pipeline, and will operate two groups of valves simultaneously and regulate.Now having occurred a valve and controlled the burner of a secondary air flow simultaneously, is that the Chinese patent of CN2106954U and CN2257589Y just discloses two kinds of burners of regulating a secondary wind at two adjusting turnover panels that form an angle of top air inlet installation and right-angle type control valve of installation respectively as notification number.These two kinds of burners can both realize regulating the purpose of the length of flame, and still, which position no matter their adjusting device be in, the capital forms powerful damping to wind, reduce the draught area of wind artificially, must use thicker airduct, but also can't carry out remote auto control.
It is a kind of simple in structure that the purpose of this utility model is to provide, and the length of flame is adjustable, and is easy to operate, can realize the semi-butterfly type undamped wind cover of remote adjustment by general butterfly valve executing agency.
The utility model is achieved in that the adjustable flame apparatus of this semi-butterfly type undamped is made up of the blast pipe at wind sheath body, cartridge, a secondary air separating shelf, wind spinning disk and wind sheath body top, the top of a described secondary air separating shelf integrated disc portions, the part that also promptly links to each other with blast pipe is horizontal, and by an axle and a semi-butterfly type air regulating board flexible connection, the diameter of semi-butterfly type air regulating board equals the internal diameter of blast pipe, and the tube wall that an end of axle passes blast pipe is connected with governor motion.
Axle on the adjustable flame apparatus of this semi-butterfly type undamped is through in the axle sleeve and the axle sleeve in the middle of the semi-butterfly type air regulating board of both sides, a secondary air separating shelf integrated disc portions top, and fixedlys connected with the semi-butterfly type air regulating board by trip bolt.The top of a described secondary air separating shelf integrated disc portions also can be stretched into along axis and reach certain altitude in the blast pipe, one end of axle passes the tube wall and the adjusting dial that is fixed on the blast pipe tube wall of blast pipe, end is equipped with the adjusting handle, be equipped with sealing gasket and gland at the middle part of dial, have set screw on the adjusting handle.
Of the present utility model simple in structure, simple operation is applicable to various oil and gas burners, by the opening angle of governor motion control semi-butterfly type air regulating board, regulates the air swirl and the ratio of eddy flow not, reaches the purpose of regulating the length of flame.When being transferred to the big air quantity of 90 degree, air quantity can reach twice, realizes undamped work.Because the movement locus of this semi-butterfly type air regulating board is consistent with butterfly valve, so can adopt butterfly valve executing agency to finish remote auto control.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is looked cutaway view for the master of the utility model wind cover.
Accompanying drawing 2 is looked cutaway view for the partial left of wind cover.
Can see that from accompanying drawing 1 the adjustable flame apparatus of the utility model mainly is made up of the blast pipe 4 at wind sheath body 1, cartridge 3, a secondary air separating shelf 5, wind spinning disk 2 and wind sheath body 1 top.One secondary air separating shelf 5 comprises integrated disc portions and drum part, top in integrated disc portions, the part that also promptly links to each other with blast pipe 4 is horizontal, and by 9 flexible connections of 7 and semi-butterfly type air regulating boards of axle, the diameter of semi-butterfly type air regulating board 9 equals the internal diameter of blast pipe 4, one end of axle 7 passes the tube wall of blast pipe 4, with the governor motion of outside, as the butterfly valve executing agency connection of manual adjustments handle or the control of realization remote auto.Cartridge 3 is positioned at the center of wind sheath body 1, according to different burners, and transferring oil or coal gas.The drum of one secondary air separating shelf 5 partly places between cartridge 3 and the wind sheath body 1, and its integrated disc portions is positioned on the axis of blast pipe 4, and the air that enters from blast pipe 4 just is divided into inside and outside two-way like this, and interior road is an air channel, and from outside is secondary air duct.Spinning disk 2 is positioned on the exit in an air channel, and the air that passes through is sprayed with the eddy flow form.Can see from accompanying drawing 2, the connected mode at the utility model semi-butterfly type air regulating board 9 and separation frame 5 integrated disc portions tops is: axle 7 is through in the axle sleeve 6 and the axle sleeve 8 in the middle of the semi-butterfly type air regulating board 9 of both sides, separation frame 5 integrated disc portions top, and fixedlys connected with semi-butterfly type air regulating board 9 by trip bolt 10.The utility model accompanying drawing is the manual adjustments mode, one end of axle 7 passes the tube wall and the adjusting dial 11 that is fixed on blast pipe 4 tube walls of blast pipe 4, end is equipped with regulates handle 14, regulate dial 11 owing to outside the tube wall of blast pipe 4, be fixed with, so the top of separation frame 5 integrated disc portions should be stretched in the blast pipe 4 along axis, its height should be greater than the radius of dial 11.Be equipped with at the middle part of dial 11 and prevent the sealing gasket 12 that air leaks and the gland 13 of fixed axis 7 usefulness, regulate on the handle 14 and have set screw 15, dial 11 is marked with and the corresponding scale of semi-butterfly type air regulating board 9 opening angles.During operation, according to the scale on the dial 11, handle 14 is regulated in rotation, makes axle 7 drive semi-butterfly type air regulating board 9 and rotates together.Being transferred to 0 degree when regulating handle 14, also is air regulating board 9 when horizontal to the left, from outsidely closes fully, and air all sprays with cyclone mode by interior road, and this moment, flame was the shortest.Being transferred to 180 degree when regulating handle 14, also is air regulating board 9 when horizontal to the right, and interior road is closed fully, and air all sprays in the direct current mode by from outside, and this moment, flame was the longest.When being transferred to 90 when spending, air by two paths simultaneously equivalent enter, at this moment, air quantity can reach twice, realizes the undamped air feed.By after regulating handle 14 air regulating board 9 being transferred to required angle, locate with regard to available set screw 15.
