Abstract

The utility model relates to a liquid spraying and atomizing nozzle, which comprises a needle valve and a needle valve body. The lower end of the needle valve comprises a cylindrical plunger, and the cylindrical surface of the plunger is uniformly provided with a plurality of spiral grooves. The utility model has the advantages of good atomizing performance, uniform atomization, small granules, simple structure, easy processing and low cost. The liquid spraying and atomizing nozzle can be used as a nozzle for various types of engines, such as diesels, gas-turbines, etc., and can also be used for spraying and atomizing other liquid and fine coal slurry, and a spraying and atomizing dust-proof device for a mine.

Description

Liquid spray atomizing nozzle
The utility model is a kind of fluid jet atomising device, relates in particular to a kind of jet atomization nozzle that is used for liquid.
Existing various types of liquid discharging atomising device such as the employed fuel nozzle of diesel engine, the fuel of one or more spray orifice ejections mostly is pencil or column through its end, atomizes by locating splash for the second time again.This oil nozzle atomization is bad, the uneven particle of fuel atomization is bigger, can not fully mix with the pressurized air in the cylinder, burn, a part of unburned fuel is discharged with exhaust, the oil consumption of motor is increased, and its black exhaust causes severe contamination to atmosphere environment, and this oil nozzle produces bigger noise, simultaneously because the bad carbon deposit that is easy to generate of atomizing stops up spray orifice.Therefore solving the existing bad problem of nozzle atomization performance, is current facing of task.
Main purpose of the present utility model is to overcome the existing defective of existing liquid discharging atomizer nozzle, and a kind of liquid discharging atomizer nozzle with good atomization is provided, as diesel injector, and fine coal slurry and other liquid atomizing nozzles.
Liquid discharging atomizer nozzle main structure described in the utility model includes: needle-valve, needle-valve body, needle-valve body inside includes the liquid inlet passage, there is spray orifice the end of needle-valve body, the needle-valve upper end includes garden cylindricality seal, the needle-valve lower end includes garden cylindricality plunger, be connected with the Cylinder of its diameter between seal and the plunger less than seal and plunger diameter, on the needle-valve body around this Cylinder, has the cavity that is connected with the liquid inlet passage, be evenly distributed with many spiral grooves on the post surface, garden of garden cylindricality plunger, needle valve end is a frustum-like shape needle-valve head.
Liquid discharging atomizer nozzle described in the utility model has good atomizing functions, and jet atomization is even, and particle is less, has reduced noise, and spray orifice is difficult for stopping up, and its simple in structure being easy to is processed, and is with low cost.
