The nozzle can be matched with most spray gun bodies or assemblies of a spray company, so that the internal manufacturing cost and the re-investment cost of customers are reduced.
The utility model discloses in, the nozzle mainly contains following part: the spraying device comprises an air cap, an air deflector and a liquid cap. Aiming at different liquids at the outlet of the nozzle among the air cap, the air guide vane and the liquid cap, the combination of different extension lengths and the atomization effect of secondary gas well solve the problem that the beard is hung in the traditional single atomization. Wherein,
(1) an air cap: the main function of the atomizing nozzle is to control the outlet speed of gas and the final atomizing angle of liquid during the second atomization under certain working pressure. Compared with the traditional air cap, the air cap achieves the purposes of reducing the gas pressure at the outlet of the nozzle and controlling the atomization angle at the outlet by adjusting the angle of the inner cavity and the outlet area. Under the condition of keeping the total flux of the gas unchanged, the gas carries out secondary low-pressure atomization on the primarily atomized liquid at a certain angle again at a lower speed and pressure in the nozzle, so that the requirements of refining particles and enlarging the angle are met.
(2) Air deflector: the main function is to divide the gas into two parts, one part of the gas atomizes the liquid in a low pressure mode according to the traditional mode, and the other part of the gas rotates through the liquid flow deflector and then carries out secondary low-pressure rotary atomization on the liquid. Compared with the traditional one-time atomization, the gas guide plate with the air holes at a certain angle is newly added, so that the liquid can be atomized twice. While the first atomization is kept, the pressure of the first atomization is reduced, and the generation of flying fog is reduced; the low-pressure gas with a certain angle which is separated out carries out secondary low-pressure atomization on the liquid again, thereby refining particles again and simultaneously enlarging the angle.
(3) A liquid cap: its main function is to control the flow rate of the nozzle. The liquid cap adopts the traditional liquid cap of a spraying company, and the flow is controlled to be finely adjusted. Because the prior art can not meet the requirements, the traditional conical sealing ring surface in the liquid cap adopts a soft sealing mode, and the main function is only used for sealing and is not used for controlling the flow. Different air caps correspond to different liquid caps, so that the use amount of liquid can be accurately controlled, and the atomization effect required during working can be kept.
The atomizing nozzle of the utility model is connected with the spray gun body through screw thread and sealed by a sealing washer; the low-dispersion wide-angle anti-whisker-hanging atomizing nozzle is made of food-grade stainless steel, and a sealing ring in contact with a medium is made of food-grade sealing materials. The working principle is as follows: when gas passes through a piston air hole of the spray gun, the piston is opened under certain pressure, the piston assembly pushes the spring to be compressed, the sealing needle assembly is driven to move backwards, and a needle tightly matched with the liquid cap is opened; the liquid flows out of the liquid cap through the liquid hole; the atomized gas flows out of the cavity of the air cap through the atomized gas holes and enters the air deflector; in the air deflector, the atomizing air is divided into two parts: one part of the gas enters an air cavity of a larger space formed by the liquid cap and the air deflector to form low-pressure atomizing gas for carrying out primary low-pressure atomization on the liquid; the other part of the liquid enters a larger air cavity formed by the air deflector and the air cap after rotating through the air deflector to form low pressure again, and the tangential rotation atomization is carried out on the liquid atomized for the first time. After the liquid is atomized for two times under low pressure, the low-dispersion atomized liquid with a certain spray angle is formed to cover the surface of the workpiece. When the gas pressure of the piston air hole is smaller than the pressure of the spring or the gas is cut off, the sealing needle is tightly matched with the liquid cap under the combined action of the spring and the piston, and the spray gun stops working.
The present invention is not limited by the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and are all included in the protection scope of the present invention.
