Abstract
The utility model discloses an adjustable nozzle for universal gas furnaces, which is characterized in that the adjustable nozzle for universal gas furnaces is provided with a nozzle body provided with a cavity in the middle, the front end of the nozzle body is provided with a nozzle hole whose hole diameter is longer than a common hole diameter, the back part of the cavity of the nozzle is provided with two or more than two fire-resistant small holes, the back end of the nozzle body has a threaded structure which is connected with a gas furnace, and the cavity inside the nozzle body is provided with a nozzle hole adjusting valve. The utility model has the advantages that the gas jetting function of the nozzle hole is scientifically separated from the fire-resistant function, when the pressure of gas is not enough, the opening of the nozzle hole can be enlarged, and the tempering phenomenon can not occur, and the residual liquid of the liquid gas is reduced.
Description
The utility model relates to combustion apparatus, is a kind of parts of burner of burning gases fuel, specifically, is a kind of nozzle.
The existing nozzle that uses the burner (as gas furnace) of gaseous fuel all adopts the maximum diameter of hole of GB regulation, in case non-return combustion and blowback, thereby its aperture is less, be reduced to when being not enough to supply with burning with the variation of combustion gas quality at gaseous-pressure like this by nozzle, can produce more unmanageable raffinate, also cause waste simultaneously.
The purpose of this utility model provides a kind ofly can effectively regulate the spray orifice openings of sizes, and can not produce the universal gas stove controlling type nozzle of tempering.
Technical solution of the present utility model is: a kind of universal gas stove controlling type nozzle, adopted the design that is different from prior art: be the nozzle body of cavity in the middle of having, the nozzle body front end has a spray orifice greater than existing conventional aperture, nozzle body cavity rear portion has two or more than two back-fire relief aperture, the helicitic texture of nozzle body rear end for being connected with gas furnace is equipped with the spray orifice control valve in the cavity in the nozzle body.
Spray orifice control valve in the utility model adopts needle-valve.Certainly, also can adopt other suitable valves.
The shank of the needle-valve in the utility model is contained in the nozzle body internal cavity, and the shank front end is arranged in spray orifice, and an adjusting device that shank is moved forward and backward is housed on the nozzle body.Certainly, needle-valve also can adopt other suitable specific constructive form.
The adjusting device that shank is moved forward and backward in the utility model comprises the adjusting rod mount pad that is contained on the nozzle body, adjusting rod is housed in the mount pad, sealing rubber circle is arranged between adjusting rod and mount pad, adjusting knob is equipped with in the adjusting rod rear end, the adjusting rod front end is positioned at the nozzle body cavity and eccentric head is housed, and the driving lever activity of an eccentric front end is flush-mounted on the shank.
The utility model has the advantages that: adopt the poly-mode of converging of branch road that the jet function and the back-fire relief function of cooking stove nozzle are scientifically separated, like this, be reduced to the variation of combustion gas quality at gaseous-pressure and be not enough to supplying with burning and produce under the situation of raffinate by spray orifice, just the spray orifice opening can be enlarged and needn't the quality worry tempering phenomenon can be occurred, the pressure gap that can adapt to multiple domestic gases such as liquefied petroleum gas, natural gas, artificial coal gas, carbon five and liquefied synthetic gas, but also can play fuel-saving effect, reduce liquefied gas residue.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is a kind of universal gas stove controlling type structure of nozzle schematic diagram of the present utility model.
Accompanying drawing has been described an embodiment of the present utility model.
The inside of nozzle body 1 is cavity.The cross section of cavity is rounded, the front end of nozzle body 1 is a spray orifice 2, the aperture of spray orifice 2 is bigger than maximum diameter of hole common, that adopt GB to stipulate, several are arranged (as 4 or 5 at the rear portion of nozzle body 1 internal cavity, certainly also can adopt other suitable number) back-fire relief aperture 3, the aperture of back-fire relief aperture 3 is less than the maximum diameter of hole of GB regulation, the shank 5 of needle-valve is housed in the cavity of nozzle body 1, the cross section of shank 5 is rectangular, mill rail groove 12 on the inwall of nozzle body cylindrical cavity, shank is embedded in the rail groove 12.One side of shank has breach 11, driving lever 14 for 10 front end of the off-centre in the adjusting device embeds, eccentric 10 rear end are connected with an adjusting rod 7, adjusting rod is loaded in the adjusting rod mount pad 6,6 of adjusting rod 7 and mount pads are equipped with sealing ring 8, be equipped with for the moving knob 9 of hand-screw adjusting rod 7 rear ends, in the rear end that has several apertures of nozzle body 1 connecting thread structure 4 is arranged, and is used for being connected with gas furnace.The front end of shank 5 is a syringe needle 13, and syringe needle 13 tips are through in the spray orifice 2, to be used to regulate the openings of sizes of spray orifice 2.Sealed pressing sleeve 15 and densification nut 16 are housed behind the sealing ring 8.Spray orifice 2 is opened on a nozzle head 17, and nozzle head 17 is screwed onto nozzle body 1 front end, to make things convenient for the installation of shank etc.
The utility model in use, combustion gas enters cavity in the nozzle body 1 by back-fire relief aperture 3, again by spray orifice 2 jetting nozzles, for burning.And needle-valve and appurtenances thereof then are used for regulating according to the combustion gas situation openings of sizes of spray orifice.Owing to spray orifice 2 only has only jet function, and the back-fire relief function of spray orifice of the prior art is realized by back-fire relief aperture 3 in the utility model, thereby has not only guaranteed gas output but also avoided the generation of accidents such as generation tempering.
