Steel ball 3 match with oil-in 13 control P mouth 11 and A mouth 12 between break-make, thus realize to magnetic valve open and close control.
When coil block 4 is not powered on, the elastic force active force of the spring 7 of dynamic iron core 5 is positioned at left side, at this moment moves in iron core 5
The push rod 6 of the heart and steel ball 3 depart from, and steel ball 3 does not has the obstruction of push rod 6, will be washed open by the oil pressure of P mouth 11 so that steel ball 3 with
Oil-in 13 separates and makes to turn between P mouth 11 and A mouth 12, and at this moment magnetic valve is in opening.
After coil block 4 is energized, electromagnet produces electromagnetic force so that dynamic iron core 5 overcomes the elastic force of spring 7, and compresses
Spring moves right, and the push rod 6 at final dynamic iron core 5 center withstands steel ball 3, and makes steel ball 3 compress oil-in 13 formation sealing, this
When P mouth 11 and A mouth 12 between be blocked, magnetic valve is closed.
After coil block 4 power-off, electromagnetic force disappears, return under the effect of the dynamic elastic force at spring 7 for the iron core 5, and push rod 6 takes off
From steel ball 3, P mouth 11 and A mouth 12 turns on again, and magnetic valve is opened.
This magnetic valve eliminates valve core structure, and structure is more simple, compact, has also dropped the processing request to valve body 1, can
Effectively reduce processing cost.In addition, this magnetic valve is only in the case of energising, spring 7 just can be compressed, and steel ball 3 is just simultaneously
Can by from the thrust of push rod 6, it is to avoid spring 7 and the long-term stress of steel ball 3 and the fatigue damage that is likely to result in, be conducive to electric
The raising in magnet valve service life.
Highly preferred embodiment of the present invention illustrates, and the various change made by those of ordinary skill in the art or remodeling are not
Can depart from the scope of the present invention.
