Embodiment Construction
[0014] Such as figure 1 As shown, the present invention is an S-type atomizing nozzle, which includes a valve body 3 with a valve seat 4 located inside the valve seat 4 , and an overflow channel 8 is left between the valve body 3 and the valve seat 4 . The valve body 3 includes a steel column 1 and a steel ball 2 fixed in one body, and the fixing method is welding or threaded connection, and the valve body 3 is controlled to expand and contract forward and backward by a solenoid valve. A tapered seam 5 is provided on the front side of the inner cavity of the valve seat 4 , and the steel ball 2 is opposite to the tapered seam 5 . When the solenoid valve is de-energized, the valve body 3 is stretched forward, so that the steel ball 2 and the tapered stop 5 are closed. At this time, the flow channel 8 is disconnected. The conical spigot 5 is separated, and at this time the flow passage 8 is opened, and the fuel is atomized after passing through the steel ball 2 and the conical s...

The invention discloses an S-shaped atomizing nozzle used in a fuel engine. The nozzle comprises a valve seat and a valve body positioned in the valve seat, wherein an overflow channel is reserved between the valve body and the valve seat; a solenoid valve controls the valve body to extend and contract forward and backward; the front side of the valve seat is provided with a spray orifice plate; at least one spray orifice communicated with the inner cavity of the valve seat is formed on the spray orifice plate; a through hole plate is arranged between the valve seat and the spray orifice plate and is provided with at least one overflow hole, and the front side of the through hole plate is sunken inward to form a rechanneled cavity which is positioned between the overflow hole and the spray orifice; and the overflow hole and the spray orifice are arranged in a staggered manner. The S-shaped atomizing nozzle has the beneficial effects that as the overflow hole and the spray orifice are arranged in a staggered manner so as to form an S-shaped injection flow channel at the front side of the inner cavity of the valve seat, the atomized fuel oil sprayed from the valve seat is impacted multiple times in the rechanneled cavity so as to generate a great quantity of turbulent flow, so that the atomized fuel oil is refined into smaller particles, thus a better atomizing effect is obtained, the combustion efficiency of the engine is improved greatly, the emission is lowered, energy sources are saved, and the market competitiveness of products is further improved.
Description
technical field [0001] The invention relates to a nozzle for a fuel engine, in particular to a nozzle with an S-shaped injection channel and good atomization effect. Background technique [0002] Atomizing nozzles for fuel engines improve engine combustion efficiency by atomizing fuel and spraying it out. At present, the known fuel injector nozzle structure generally adopts a straight-out structure. The liquid flows through the nozzle hole in a direct and smooth path through the nozzle structure. This structure is simple, but under the premise of the same number and diameter of the nozzle hole, the atomization effect of the liquid after passing through the nozzle hole is poor. As far as the nozzle is concerned, if you want to obtain better atomization effect of fuel or liquid, the only way is to increase the number of nozzle holes and reduce the hole diameter, but this will bring a significant increase in processing and manufacturing costs. The "nozzle device" disclosed by...
