The invention aims at providing a long
needle valve hole plate type electronic control oil atomizer without static leakage. The long
needle valve hole plate type electronic control oil atomizer comprises an
electromagnetic valve assembly, an oil atomizer body, a
nozzle, a long
needle valve, a limiting sleeve, a control plate, a middle block and an
electromagnetic valve seat. An oil cavity is designed in the oil atomizer body, the interior of the oil cavity is completely filled with high-pressure
fuel oil, the upper end and the lower end of a needle valve
coupling piece are in the high-pressure environment, the
pressure difference of the upper end and the lower end is close to zero,
fuel oil leakage of the electronic control oil atomizer due to a fit clearance of inner
coupling pieces is avoided, static leakage of the
fuel oil is avoided,
power consumption of an
oil pump is reduced, the device working stability is improved, and the oil atomization character is improved. The control plate is designed in a control cavity, in the early stage of oil releasing of the control cavity, the control plate closes an annular oil inlet amount hole in the middle block, the dynamic fuel oil leakage amount generated during actual work of the electronic control oil atomizer can be effectively reduced, accordingly, fuel oil losses are reduced, and the oil atomization pressure of a
common rail pipe is effectively increased.
