Abstract
The utility model discloses a pressure atomizer in the field of combustion comprising an external connection and a nipple positioned on the external connection, the external connection and the nipple are provided with a fuel channel, a spout is arranged on the top of the external connection, and outside of the nipple is provided with an airflow channel along the axis, and a cavity is arranged inside the external connection, and the cavity has a revolving solid, and an oil passage passes through the revolving solid, the oil passage is communicated with the fuel channel, a groove is positioned on the head face of the revolving solid, the groove is communicated with the airflow channel. When using, a subpressure takes shape as the fuel reaching the spout, the compressed air flow to the groove of the revolving solid to form a bow wave, by which the fuel oil can be atomized and burnt fully, moreover, the oil passage can be jammed so as to prevent the nozzle from being burning out because of backfire, and the service life is prolonged greatly.
Description
Technical field
The utility model relates to a kind of nozzle, particularly a kind of pressure atomized fog jet that belongs to combustion field.
Background technology
Existing burning nozzle; comprise coupling and nipple; spout is arranged in the coupling, be connected on during use on the device that oil, gas are provided, fuel oil and compressed air fully mix in nipple, atomize; burn from the spout ejection; its weak point is: the atomizing when the ejection of mixing back, nipple the inside of fuel oil and compressed air causes burning insufficient inadequately, and oil duct stops up through regular meeting, causes tempering during burning easily; burn out nozzle, cause reduce greatly service life.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of nozzle that can make mist sufficient combustion and long service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of nozzle, comprise coupling and be installed in nipple in the coupling, be provided with the fuel gallery in the inside and outside joint, the coupling end is provided with spout, and the nipple outer surface is provided with gas channel vertically, cavity is arranged in the coupling, rotary body is installed in the cavity, and a rotating body is penetrated with oil duct, and oil duct communicates with the fuel gallery, the rotary body end face is provided with groove, and groove communicates with gas channel.
The beneficial effects of the utility model are: a rotary body is housed in the cavity of coupling, a rotating body is penetrated with oil duct, end face is the worm gear shape, its groove communicates with gas channel, during use, when arriving nozzle, fuel oil forms negative pressure, form eddy current and make fully atomizing of oil behind the gas process rotary body groove, sufficient combustion, and oil duct can not stop up, and can avoid because of tempering burns out nozzle, and prolong service life greatly, pressure than the high-pressure oil gas hybrid mode of existing traditional oil nozzle is lower, also power and energy saving more.

The specific embodiment
Referring to figs. 1 through Fig. 8, a kind of nozzle, comprise coupling 2 and the nipple 1 that is installed in the coupling 2, be provided with fuel gallery 11,21 in the inside and outside joint, coupling 2 ends are provided with spout 3, nipple 1 outer surface is provided with gas channel 12 vertically, in the coupling 2 cavity is arranged, also have rotary body 4 in the cavity, be penetrated with oil duct 41 in the rotary body 4, oil duct 41 communicates with fuel gallery 11,21, and the groove 42 on the rotary body 4 communicates with gas channel 12.During use, coupling 2 is fixed on the Gas appliance 7, and fuel oil enters fuel gallery 11,41 by the fuel filler 71 of Gas appliance 7, forms negative pressure when arriving spout 3, compressed air is entered by gas access 72, flow through the groove 42 of rotary body 4 by gas channel 12, form eddy current and arrive spout 3 places, make atomizing fuel oil, sufficient combustion, and oil duct can not stop up, and can avoid because of tempering burns out nozzle, and prolong service life greatly.
As further improvement of the utility model, described nipple 1 afterbody is provided with screw thread, and cavity inner wall also is provided with screw thread, and interior coupling spins by screw thread, like this can be fastening easily and pull down, and practicality increases.
As further improvement of the utility model, the end face of described rotary body 4 is the worm gear shape, and its groove 42 shape in the shape of a spiral evenly distributes, the better effects if of the out-of-date formation eddy current of flow of the compressed gas.
In addition, also be provided with lining 6 in the described spout 3, can increase the service life of spout 3.The head of nipple 1 is equipped with O RunddichtringO 5, energy effective isolation fuel oil and compressed air during work, and fuel oil enters from the oil duct of nipple 1, and fuel oil-gas enters from the groove on nipple 1 surface, arrives spout 3 and can not meet before.
Above-mentioned just the utility model preferred embodiment but should not constitute restriction of the present utility model, so long as adopt the technical scheme that is equal to the utility model also should be within the protection domain of the invention.
