Description
Technical field
The present invention relates to valve technology field, more particularly to a kind of bistable electromagnetic valve and its electromagnetic coil, electromagnetic coil
Processing method.
Background technology
Technical field of refrigeration equipment is the larger technical field of energy consumption, with deepening continuously for energy conservation and environmental awareness,
Refrigeration plant is also constantly developing towards energy saving, reliable direction.Switching valve assume responsibility for dropping as the critical piece of refrigeration plant
Low energy consumption, put forward efficient main task.At present, bistable electromagnetic valve has been obtained extensively with its own advantage in refrigeration plant
Application.
Please refer to Fig.1 and Fig. 2, Fig. 1 are the structure diagram of bistable electromagnetic valve in the prior art, Fig. 2 is electricity shown in Fig. 1
The characteristic curve of permanent magnetic, spring force and dynamic iron core stroke suffered by the dynamic iron core of magnet valve.The bistable electromagnetic is briefly described below
The primary structure of valve and its at work there are the defects of.
As shown in Figure 1, above-mentioned bistable electromagnetic valve includes main valve 2 ', electromagnetic coil 1 ' and connection main valve 2 ', electromagnetic coil
1 ' bolt assembly 3 '.Main valve 2 ' includes valve body 21 ', arranged on valve body 21 ' internal static iron core 22 ', dynamic iron core 23 ' and both ends point
Not Lian Jie static iron core 22 ', the spring 24 ' of dynamic iron core 23 ', static iron core 22 ' is additionally provided with permanent magnet close to the side of dynamic iron core 23 '
25′。
In the course of work, electromagnetic field is produced after the logical positive electricity of electromagnetic coil 1 ', the electromagnetic field produce attract dynamic iron core 23 ' to
The mobile electromagnetic force Q of static iron core 22 'Inhale, spring 24 ' produces and repels dynamic iron core 23 ' and make it away from the spring force P of static iron core 22 'Row,
And permanent magnet 25 ' produces and attracts dynamic iron core 23 ' to the mobile permanent magnetic F of static iron core 22 'Inhale, dynamic iron core 23 ' is in Q with joint effortsInhale+FInhale-
PRowMove right O points and the actuation of static iron core 22 ' into Fig. 2 under effect；
After electromagnetic coil 1 ' powers off, electromagnetic force QInhaleDisappear, dynamic iron core 23 ' is being attracted retentivity FInhale-PRow(as shown in Fig. 2,
Numerical value is Fo-Po) under the action of keep attracting state；
Magnetic field is produced again after the logical reversely electricity of electromagnetic coil 1 ', and dynamic iron core 23 ' is subject to the electricity of the magnetic field repulses dynamic iron core 23 '
Magnetic force QRow, spring 24 ' produce spring force PRow, permanent magnet 25 ' produce permanent magnetic FInhale, dynamic iron core 23 ' is in Q with joint effortsRow+PRow-FInhale
Under the action of be moved to the left S points in Fig. 2, disengaged with static iron core 22 '；
After electromagnetic coil 1 ' powers off, electromagnetic force QRowDisappear, dynamic iron core 23 ' is disengaging retentivity PRow-FInhale(as shown in Fig. 2,
Numerical value is PS-FS) under the action of keep disengaged condition.
However, as shown in Fig. 2, the characteristic curve of the above-mentioned power of spring 24 ' is straight line, spring force PRowDisengaging the numerical value of side
(it is PS) smaller, the i.e. disengagement retentivity P of dynamic iron core 23 'Row-FInhale(numerical value PS-FS) too small, cause to use process in system
In since the factors such as vibration can not stablize, reliably keep disengaged condition, easily generation position offset causes dynamic iron core 23 '
Solenoid valve produces leakage or collaborates；Accordingly, spring force PRowIt is larger in the numerical value (being Po) for being attracted side, therefore dynamic iron core
23 ' actuation retentivity FInhale-PRow(numerical value Fo-Po) is also smaller, causes dynamic iron core 23 ' not stablize, reliably keeps being attracted
State, it is more sensitive or be easier to be influenced be subject to system contaminants.For example, in the presence of impurity, the stroke of dynamic iron core 23 ' easily deviates
To O ' points, the such suction of permanent magnet 25 ' decrease speed is very fast, causes actuation retentivity significantly to reduce, is more prone to cause electromagnetism
Dynamic iron core 23 ', which can not be maintained at, after valve commutation is attracted side.
In addition, application of the spring in solenoid valve, also causes the service life of solenoid valve entirety to be subject to certain restrictions, Wu Fada
