Embodiment
Below in conjunction with accompanying drawing citing, the present invention is described in more detail:
Composition graphs 1 ~ 3, the present invention proposes a kind of suction dynamic formula natural gas injection electromagnetic valve device newly, can control the natural gas injection of duel fuel engine.
The present invention is made up of parts such as connector assembly 1, sliding bearing 2, spring 3, coil 4, magnetic conduction casing 5, rear case 6, armature 7, tightening nut 8, bearing support 9, central shaft 10, cone valve 11, front covers 12.Adopt and inhale dynamic formula principle, have through hole at the center of central shaft 10 and cone valve 11 radial direction, after coil 4 is energized, armature 7 adhesive, rock gas passes through the through hole of central shaft 10 successively, the radial hole of cone valve 11, and the gap between cone valve 11 and front cover 12, finally spray, spaces compact, structure is simple.Central shaft 10 adopts sliding bearing 2 to realize straight line motion, sliding bearing 2 is processed with the lubrication groove of annular, can stores lubricant oil, reduces friction, selects sliding bearing to reduce the diameter dimension of whole valve body simultaneously.Magnetic conduction casing 5 and armature 7 adopt soft magnetic material, and other adopt non-magnet material, produce magnetic field, and form magnetic circuit after coil 4 is energized among soft magnetic material, drive armature 7 and are with central shaft 10 straight line motion; When after coil 4 power-off, magnetic field dissipate, under the effect of spring 3, central shaft 10 resets.Mounting spring 3 between central shaft 10 and armature 7, ensures that valve is in normally off.Contact with magnetic conduction casing 5 when adhesive to prevent armature 7, and because hysteresis effect armature 7 does not reset after making coil 4 power-off, when designing, the shaft shoulder of central shaft 10 fixed armature retains the distance of 0.5-1mm near between a side end face of magnetic conduction casing 5 near a side end face of magnetic conduction casing 5 and armature 7, shaft shoulder diameter is greater than the aperture of installing sliding bearing 2 in magnetic conduction casing 5.Central shaft 10 center is in axial direction processed with a through hole, and the radial direction of cone valve 11 is processed with through hole, and central shaft 10 and cone valve 11 are threaded connection, and the central through bore of central shaft 10 and the radial hole of cone valve 11 communicate.
The object of the present invention is achieved like this: central shaft 10 adopts sliding bearing 2 to realize straight line motion, sliding bearing 2 is processed with the lubrication groove of annular, can stores lubricant oil, reduces friction, selects sliding bearing to reduce the diameter dimension of whole valve body simultaneously.Central shaft 10 center is in axial direction processed with a through hole, and the radial direction of cone valve 11 is processed with through hole, and central shaft 10 and cone valve 11 are threaded connection, and the central through bore of central shaft 10 and the radial hole of cone valve 11 communicate.Magnetic conduction casing 5 and armature 7 adopt soft magnetic material, and other adopt non-magnet material, and armature 7 is fixed by tightening nut 8.
During original state, central shaft 10, under the pulling force of spring 3, promotes cone valve 11 and makes solenoid valve normally closed; When connector assembly 1 switches on power, coil 4 alives, and forms electromagnetic field hold armature 7 at magnetic conduction casing 5, and armature 7 is with central shaft to overcome spring tension and is driven cone valve 11, solenoid valve is opened, and natural gas flow is through the gap ejection of the center hole of central shaft 10, cone valve 11 radial hole and cone valve front end.The distance of the shaft shoulder reserved 0.5-1mm near between a side end face of magnetic conduction casing 5 near a side end face of magnetic conduction casing 5 and armature 7 of central shaft 10 fixed armature, prevent armature 7 from contacting with magnetic conduction casing 5 when adhesive, due to hysteresis effect make coil 4 power-off after armature 7 do not reset.
Retain air gap between the shaft shoulder left end face of central shaft 10 fixed armature 7 and armature 7 left end face, after avoiding coil 4 power-off, hysteresis effect causes armature 7 not reset.The through-hole aperture of central shaft 10 is 5mm, and coil adopts 1.5mm wire gauge, 50 circles, and magnetic conduction casing 5 and armature 7 adopt DT4 material.Coil 4 is arranged on the center shaft 10, is surrounded by permeability magnetic material DT4.During coil 4 no electric circuit, central shaft 10, under the pulling force of spring 3, promotes cone valve 11 and makes solenoid valve normally closed.Central shaft 10 adopts sliding bearing 2 to realize straight line motion, sliding bearing 2 is processed with the lubrication groove of annular, can stores lubricant oil, reduces friction, selects sliding bearing to reduce the diameter dimension of whole valve body simultaneously.After coil 4 is energized, armature 7 adhesive, rock gas by the through hole of central shaft 10, the radial hole of cone valve 11, the gap between cone valve 11 and front cover 12, finally sprays successively.
