Embodiment
Embodiment:
The utility model, when assembling, is first pressed shown in Fig. 4, fitting seat 6 and pole shoe 7 is pressed in armature pipe 8, and has welded on request the assembling of armature pipe assembly 5; Then by Fig. 3, be shown in armature pipe assembly 5 and pack armature component 9 and guide sleeve 10 into, reinstall spring 12, the spring regulating lever 11 of last grip upper O-shape ring is screwed into, and protective cap 17 is arranged on to the top of valve assembly 4, completes the assembling of valve assembly 4; Afterwards coil block 3 is enclosed within on valve assembly 4, then packs the rear closing in of coil housing 2 into and divide injection moulding by coil block 3 plug pin portion, finally the valve of injection formed is packed in valve body 1, and put protective cap 17, completed the solenoid valve shown in Fig. 2.
In this electromagnetic valve structure, as shown in Figure 2, suction port 15 is communicated with all the time with control mouth 13, control the main passage that mouth 13 connects major-minor channel-type variable intake manifold, air outlet 14 connects the subaisle of major-minor channel-type variable intake manifold, and solenoid valve changes by changing the logical state that closes of air outlet 14 flow of controlling mouth 13 and air outlet 14.System provides inlet pressure P to suction port 15
0, during no electric circuit, spring 12 is given 9 one of armature components pressure F vertically downward
spring force, guaranteeing the conical seal (contact) face 16 sealing surfaces laminatings of armature component 9 and valve body 1, air outlet 14 is closed, and the flow of now controlling mouth is maximum; When solenoid valve is switched on, at F
electromagnetic forceunder (direction vertically upward) effect, armature component 9 overcomes F
spring force(direction vertically downward) moves up, and open gradually air outlet 14, controls also corresponding reducing thereupon of mouthfuls 13 flow.
This solenoid valve has adopted basin type electromagnet structure, as armature component 9 and pole shoe 7, F
electromagnetic forcehave ratio characteristic, armature component 9 each displacement place in travel range is subject to F
electromagnetic forceapproximately equal, in this structure, F
electromagnetic forcewith suction port 15 pressure F
atmospheric pressurethe same F of sum
spring forceopposite sign but equal magnitude, active force and reaction force, therefore change F by adjusting electric current each other
electromagnetic forcesize, just can change the uninterrupted of electromagnetic valve mouth 13, and electric current and flow approach proportionate relationship.
Working principle: the suction port 15 of solenoid valve, control mouth 13 and air outlet 14 are as shown in Figure 2, suction port 15 is communicated with all the time with control mouth 13, control the main passage that mouth 13 connects major-minor channel-type variable intake manifold, air outlet 14 connects the subaisle of major-minor channel-type variable intake manifold, and solenoid valve changes by changing the logical state that closes of air outlet 14 flow of controlling mouth 13 and air outlet 14.The logical 0.2MPa air pressure of suction port 15, during no electric circuit, acts on the F on armature component 9
spring force(direction vertically downward) is greater than the F that it is subject to
atmospheric pressure(direction is vertically upward), armature component 9 is fitted with the sealing surface of valve body 1, and air outlet 14 is closed, and the flow of now controlling mouth 13 is maximum; During solenoid valve energising, coil block 3 produces F
electromagnetic force, act on the F on armature component 9
electromagnetic force(direction vertically upward) and F
atmospheric pressure(direction vertically upward) sum is greater than F
the initial precompression of spring(direction is vertically downward), armature component 9 moves upward, and open air outlet 14, controls mouthful 13 flows and decline; Solenoid valve adopts basin type electromagnet structure, the F that armature component 9 is subject to
electromagnetic forceonly relevant with coil current size, and proportion relation, so when coil current changes,
F
electromagnetic forceratio changes thereupon, due to F
