Operation principle:
Electromagnet assembly constitutes electric magnet after connecing electricity, and this electromagnetic valve is a kind of normally close valve.In the case of coil 4 power-off, spring 8
Elastic force dynamic iron core 6 is pushed up downwards, make the sealing gasket 65 of lower end of iron core 6 and valve body 1 upper fluid passage 13 phase seal, thus
Fluid inlet 11 and fluid issuing 12 are cut off, now closed electromagnetic valve.After coil 4 is energized, coil 4 and static iron core 7 are constituted
Electric magnet produces electromagnetic force, makes iron core 6 overcome the elastic force of spring 8 to move upward, so that the lower end of dynamic iron core 6 leads to fluid
Road 13 is separated, and makes fluid passage 13 open wide, so that turning between fluid inlet 11 and fluid issuing 12, at this moment electromagnetic valve leaves
Open.
In actual application, coil 4 meeting power on/off continually, so that electromagnetic valve constantly opens and closes,
During this, dynamic iron core 6 moves up and down in sleeve pipe 5 repeatedly, and this electromagnetic valve arranges wear ring 61 in dynamic iron core 6 periphery,
Avoid dynamic iron core 6 outer wall to contact with the direct of sleeve pipe 5 inwall, also avoid metal and directly contact the produced mill of friction
Damage, be effectively increased the service life of dynamic iron core 6, and then improve the service life of whole electromagnetic valve.
It addition, the static iron core 7 of this electromagnetic valve be provided centrally with hand lever 71, hand lever 71 can manually regulate its install
Upright position, owing to the upper end of spring 8 offsets with the lower end of hand lever 71, and its lower end and dynamic iron core 6 offset, hand lever 71
The difference of the upright position installed can bring different precompressions to spring 8, and this precompression will directly affect opening of electromagnetic valve
Qi Dian.In application process, the most multiple electromagnetic valves in the equipment applied, in order to ensure the one of each electromagnetic valve opening point
Cause property, the precompression of spring 8 just to keep consistent, this just processing and assembling to product propose the highest requirement.This electromagnetism
The hand lever 71 of valve can manually regulate, and by regulating the position of hand lever 71, just can regulate the pre-of spring 8 very easily
Pressure, thus reach the purpose of electromagnetic valve for adjusting opening point, simple, convenient.
Highly preferred embodiment of the present invention illustrates, those of ordinary skill in the art the various changes made or remodeling are the most not
Can depart from the scope of the present invention.
