It is connected between slot by stomata；Second air channel is made of the multiple annular concentric slot structures for being arranged in valve seat upper surface, each
It is connected between annular groove by stomata.The structure can form biggish circulation in the lesser situation of design lift of valve block
Area.Circulation area is larger to mean that the electric spray valve will possess broader range of flow, can be with the power model of matched engine
It encloses and also increases accordingly, purposes is more extensive.Since lift is smaller, stroke speed when valve block is taken a seat is smaller, and this design can
To mitigate the shock of movement parts, increase the sealing surface service life.
Further, the shell is made of hard aluminium alloy, is avoided the shell and is done to the electromagnetic valve components
It disturbs, improves response speed under the premise of proof strength.Meanwhile alleviating the weight of EFI valve assembly.
Further, electromagnetic valve components and valve hole part are coaxially mounted on shell.
Further, the iron core of the iron-core coil is E shape, is stacked, can be provided more using iron silicochromium flaky material
Big electromagnetic force, while effectively inhibiting the current vortex in the iron core to generate, and then weaken current vortex to the electromagnetic valve components
The influence of response speed.
Further, between magnet valve component and shell, between valve hole part and shell and the fuel gas inlet and combustion of shell
It is mounted on the O-ring seal of high performance fluorubber material around gas outlet, blocks the leakage path of combustion gas, improves EFI
The reliability and safety in utilization of valve.
Gaseous propellant engine fuel gas electric spray valve of the present invention, due to above structure, electromagnetic valve components energization
When, under electromagnetic force, armature pulls valve block to move up, and sealing surface is unfolded into blast tube, electromagnetic valve components power-off
When, under the action of spring force and gravity, valve block is taken a seat, and the lower surface of valve block is bonded to form sealing surface with the upper surface of valve seat
It forms sealing surface and blocks blast tube, set in the structure that the lower surface of valve block and the upper surface of valve seat are all made of annular concentric slot
Meter, the structure can form biggish circulation area, possess electric spray valve will more in the lesser situation of design lift of valve block
Wide range of flow can also be increased accordingly with the power bracket of matched engine, and purposes is more extensive.The present invention has response speed
The features such as degree is fast, and gas metering is accurate, and covering power per cylinder range is wide.It is 90kW~600kW that the present invention, which is applied to power per cylinder,
High speed gas machine or dual fuel engine.When fully opening, actual internal area is 400mm2~500mm2, lift 0.38mm
