Between iron core 8 and spring base 13.After coil 9 is powered, iron core 8, armature 11 are magnetized, and are formed between iron core 8 and armature 11
Magnetic loop, armature 11 moves upwards after the pretightning force for overcoming back-moving spring 10 is acted on by electromagnetic force, in whole motion process,
Armature 11 is axially moved the cooperation between circumferentially positioned 4 guide pads 29 and valve element 18 by valve seat 31 to control reality
Existing, until the upper surface of spring base 13 is in contact with the lower surface of iron core 8, armature 11 is after the maintenance a period of time of the position, line
The power-off of circle 9, the electromagnetic force that armature 11 is subject to disappear, in the presence of the back-moving spring 10 between iron core 8 and spring base 13, armature
11 move downward, until armature 11 comes back to initial position.Open 2 circumferential tonifying Qi holes respectively on four ribs 19 of valve element 18
20, response speed is improved, increases circulation area, while quality can be also reduced, improve reliability.Set at circumferential tonifying Qi hole 20
The outlet annulus 24 of certain angle, flow losses are reduced, increase discharge coefficient.Using axially main 28 direct air inlet of air drain and circumference
The mixed admission mode of the air inlet of tonifying Qi hole 20, increase charge flow rate coefficient, increase air inflow, while air-flow can be avoided to interfere,
Gas circuit is set to reach balance.Outlet annulus 24, face sealing, voltage stabilizing balance, and wider annulus are used between valve element 18 and valve seat 31
Area can reduce impact, improve reliability.
As shown in figure 4, in order to prevent combustion gas reverse leakage, the reliability and security of fuel gas injection valve, this practicality are improved
It is new to employ the structure of floating valve seat 7.Floating valve seat 7 can be when magnetic valve external pressure height be with air pressure inside by electromagnetic valve lock
Extremely, it effectively prevent the reverse leakage of combustion gas.Floating valve seat 7 is made up of 7 parts：Guide base 30, valve seat 31 and valve seat are answered
Position spring 37, O-ring seal 33, packing washer 35, deformable seal circle 36, elastic washer 32.Guide base 30 is consolidated by bolt
It is scheduled on valve body 4, valve seat 31 is arranged on guide base 30.The inner ring of guide base 30 carries T-shaped structure, with the outer ring of valve seat 31
T-shaped structure is engaged.The both ends of valve seat back-moving spring 37 are separately fixed on valve seat 31 and valve element 18, and keep certain pretension
Power.
In order to prevent gas leakage between valve seat 31 and guide base 30, installed additional between valve seat 31 and guide base 30 double
Anti-gas-leak structure, the first weight anti-gas-leak structure are the installation deformable seal circles above valve seat 31 and the junction of guide base 30
36, the outer of deformable seal circle 36 is pressed in the mounting groove on guide base 30 and valve body 4, passes through guide base 30 and valve body
Bolt pretightening between 4 is fixed.Install packing washer 35 above the interior edge of deformable seal circle 36 additional, valve seat is fixed on by screw 34
On 31, packing washer 35 ensures uniform force, strengthens sealing.The material of deformable seal circle 33 uses deformable soft modeling
Material, ensures that it does not influence the motion of valve seat 31.Second resealing is installed additional in the T-shaped junction of valve seat 31 and guide base 30
Two layers of O-ring seal 33, further enhances sealing.T-shaped junction between valve seat 31 and guide base 30 has installed one layer additional
Elastic washer 32, vibratory impulse power during contact is reduced, serves the effect of damping.Effectively increase the reliable of magnetic valve
Property.
As shown in figure 5, valve seat 31 is by the elastic force F4 of valve seat back-moving spring 37, magnetic valve the external gas pressure F1 and F2, electromagnetism
The effect of gaseous-pressure F3 and the thrust of valve element 18 inside valve.Valve element 18 is acted on by back-moving spring elastic force.The gas below magnetic valve
Pressure is more than magnetic valve air pressure inside, and magnetic valve the external gas pressure F1, F2 are respectively acting on the lower section of valve seat 31 and outlet annulus 24
Place, the lower contact area of valve seat 31 are much larger than outlet annulus 24, and therefore, F1 is much larger than F2, is expanded to and leads in the external gas pressure
Before causing the upward motion of valve element 18, the external gas pressure F1, F2 overcome the initial tension of spring of back-moving spring 10, and valve seat 31 is together with valve
Core 18 moves upwardly together.Valve seat 31 is moved upwardly until that spring base 17 is in contact with electromagnet.Even if now electromagnet is powered,
Valve element 18 can not also move upwards, and magnetic valve can not be opened.Magnetic valve is locked.
When magnetic valve inner and outer air pressure recovers normal, valve seat 31 moves back down in the presence of valve seat back-moving spring 37
It is in situ.If now electromagnet is powered, valve element 18 still remains stationary as, and magnetic valve is normally-open.Electromagnetism when wanting to close magnetic valve
Iron powers off, and valve element 18 moves downward in the presence of back-moving spring, closed electromagnetic valve.If now electromagnet is not powered on, valve seat
31 move back down to original position together with valve element 18 in the presence of back-moving spring 10, and magnetic valve remains turned-off.Want to open electricity
During magnet valve, electromagnet is powered, and valve element 18 moves upwards under armature drive, and magnetic valve is normally-open.
Before engine start-up operation, gas is vertically flowed into valve body 4 by air inlet 25, is flowed into and is filled along diversion cavity 27
Inside full valve body 4.
When engine induction stroke, after coil 9 is powered, armature 11 is overcome back-moving spring by the effect of electromagnetic force
Moved upwards after 10 pretightning force, motion is separated band movable valve plug 18 with the surface of valve seat 31 upwards, and now, gas circuit is opened, magnetic valve
Open, gas is flowed into by the axially mixed admission mode in main air drain 28 and circumferential tonifying Qi hole 20, passes through the ring of the crisscross distribution of multiple tracks
Chamber 22, injection valve is vertically finally flowed out by gas outlet 27, flow into gas hood；Fuel flows into fuel anemostat 3 by gas hood 2, then leads to
Cross each annular groove 38 and be injected to combustion gas mixing area, because the annular groove 38 on branch pipe takes form circumferentially and mutually in 90 °, make
Combustion gas mixing area can be flowed into by this series of annular groove by obtaining gaseous fuel, and make the gaseous fuel warp for being ejected into mixed zone
After crossing air inlet tear and turbulent flow, fuel can be carried out sufficiently mixing and is flowed into again in cylinder with air.
After engine induction stroke terminates, coil 9 powers off, and the electromagnetic force that armature 11 is subject to disappears, in iron core 8 and spring
Seat 13 between back-moving spring in the presence of, armature 11 moves downward, band movable valve plug 18 move downward, until the surface of valve element 18 with
The surface of valve seat 31 is bonded, and returns to initial position, and gas circuit is closed, and Fuelinjection nozzle 1 is closed, and fuel is in tracheae main part
Flowing is also just basic to be stopped, and fuel is just stored in gas hood 2 and fuel injection pipe 3.Until during next induction stroke, fuel spray
Penetrate valve 1 and cylinder valve to open, be stored in gas hood 2, the fuel in fuel injection pipe 3 can be pushed to combustion gas by follow-up fuel and mix
Area is closed, cylinder is entered after being mixed with air, which thereby enhances the response of whole gas handling system supply.
