The model utility content
The purpose of the utility model is defective and the deficiency to above-mentioned existing technology, for people provide a kind of simple in structure, low cost of manufacture, atomizer nozzle that atomizing effect is good, is used for fuel engine.
The utility model solves its technical problem, and the technological scheme that is adopted is: the valve body that this S type atomizer nozzle comprises valve seat and is positioned at valve seat, leave flow channels between valve body and valve seat; This valve body is elastic by electromagnetic valve, is provided with the taper seam in the valve base cavity front side, and the front side of valve seat is provided with jet orifice plate; Offer at least one spray orifice that communicates with valve base cavity on this jet orifice plate; Between valve seat and jet orifice plate, be provided with orifice plate, and offering at least one flowing hole on the orifice plate excessively, and the front side indent of orifice plate forms the chamber of changing its course excessively; This changes its course the chamber between flowing hole and spray orifice, and described flowing hole and spray orifice shift to install.
Described flowing hole was positioned at the center of orifice plate, and described spray orifice is provided with a plurality of, and all departed from the center of jet orifice plate.
Described spray orifice is positioned at the center of jet orifice plate, and described flowing hole is provided with a plurality of, and the center of equal offset via plate.
Described valve body comprises steel column and the steel ball that is fixed in one, and its means of fixation is welding or is threaded, and the taper seam of steel ball and valve base cavity front side is relative.
Described orifice plate excessively and valve seat are processed into one.
The described means of fixation of crossing orifice plate and valve seat is riveted joint, and welding is threaded the interference crimping.
The described means of fixation of crossing orifice plate and jet orifice plate is riveted joint, and welding is threaded the interference crimping.
The utility model forms the injection runner of S type because flowing hole and spray orifice shift to install in the front side of valve base cavity, the vaporific fuel oil that therefore sprays from valve seat can be in the chamber of changing its course multiple impact; Produce a large amount of turbulent flows; Make vaporific fuel oil be refined into littler particle, thereby obtain better atomizing effect, engine combustion efficiency is improved greatly; Reduce discharging, practiced thrift the energy.And this product structure is simple, and is easy to process, and low cost of manufacture has further improved the competitiveness of product in market.

Embodiment
As shown in Figure 1, the utility model is a kind of S type atomizer nozzle, and it comprises that valve seat 4 is positioned at the valve body 3 of valve seat 4, leaves flow channels 8 between valve body 3 and valve seat 4.Described valve body 3 comprises the steel column 1 and steel ball 2 that is fixed in one, and its means of fixation is welding or is threaded, and this valve body 3 is elastic by electromagnetic valve.Be provided with taper seam 5 in valve seat 4 inner chamber front sides, and steel ball 2 is relative with taper seam 5.When solenoid valve cut off the power supply, valve body 3 protracted, and made steel ball 2 and taper seam 5 closures; Flow channels 8 disconnections this moment, when solenoid valve is switched on, valve body 3 indentation backward; Steel ball 2 was opened with the taper seam in 5 minutes, and this moment, flow channels 8 was opened, and fuel oil is passing through steel ball 2 and the 5 back atomizings of taper seam.The advantage that valve body 3 is fixedly connected with steel ball 2 through steel column 1 not only is to process more convenient, and because the smoothness of steel ball 2 itself is high, has guaranteed the sealing when steel ball 2 and taper seam 5 are closed.The front side of valve seat 4 is provided with jet orifice plate 7, on jet orifice plate 7, offers at least one spray orifice 11 that communicates with valve seat 4 inner chambers, and fuel oil is through spraying from spray orifice 11 behind the inner chamber of valve seat 4.Between valve seat 4 and jet orifice plate 7, be provided with orifice plate 6, and crossed orifice plate 6 and can be processed into one with valve seat 4, also can be through riveted joint; Welding is threaded, and modes such as interference crimping are fixedly connected; Crossing orifice plate 6 also can be through riveted joint with jet orifice plate 7; Welding is threaded, and modes such as interference crimping are fixedly connected.Offering at least one flowing hole 9 on the orifice plate 6 excessively; And the front side indent of crossing orifice plate 6 forms the chamber 10 of changing its course; This changes its course chamber 10 between flowing hole 9 and spray orifice 11, and flowing hole 9 shifts to install with spray orifice 11, therefore forms the injection runner of S type in the front side of valve seat 4 inner chambers.From the vaporific fuel oil of valve seat 4 ejection can be the chamber 10 of changing its course in multiple impact, produce a large amount of turbulently, make vaporific fuel oil be refined into littler particle, thereby obtain better atomizing effect.Be positioned at the center of orifice plate 6 at the flowing hole 9 described in first embodiment, described spray orifice 11 is provided with a plurality of, thereby and the center of all departing from jet orifice plate 7 form the injection runner of a plurality of S types.
