Abstract
The utility model belongs to a non-material filling envelop shape guiding valve action type electromagnetic valve. The non-material filling envelop shape guiding valve action type electromagnetic valve is a pulse electromagnetic valve whose opening and closing states can be changed following the different polarities of external applied voltage. The non-material filling envelop shape guiding valve action type electromagnetic valve is characterized in that a fixing iron core which is composed of a constant magnet and a magnetism conductive sleeve is used, the non-material filling envelop shape guiding valve action type electromagnetic valve is driven by a pulse signal, and the working voltage of the non-material filling envelop shape guiding valve action type electromagnetic valve is low. The utility model has the advantages of less power consumption and no noise. The non-material filling envelop shape guiding valve action type electromagnetic valve can not heat, and can continuously work. The non-material filling envelop shape guiding valve action type electromagnetic valve is very suited for being used as a fluid switch valve in the process of automatic control.
Description
The utility model belongs to a kind of no stuffing box type pilot valve operating type solenoid valve, particularly a kind of impulse electromagnetic valve that can change its on off state with the change of executing pulse polarity outward.
Existing no stuffing box type pilot valve operating type solenoid valve will make valve body open, and must switch on thereon, in case outage, then valve body is closed.So this solenoid valve needs long-time energising, easily heating easily punctures, and power consumption is bigger, and Back drop is arranged.It in equipment an easily worn part.
The purpose of this utility model is a kind of electromagnetic valve that designs for the deficiency that overcomes above-mentioned solenoid valve.The switch of this solenoid valve is to change with the change of executing pulse polarity outward, when outside execute pulse and disappear after, still keep its former on off state.
For this reason, the utility model has designed a kind of coil that comprises, yoke, and moving core, the spring separation sleeve, the main valve valve plug, the main valve valve seat, the solenoid valve that coil rack is formed, and have a fixed iron core that constitutes by permanent magnet and concentrating flux sleeve.Concentrating flux sleeve extremely closely links to each other with one of permanent magnet, and concentrating flux sleeve is enclosed within the upper end of separation sleeve.The fixed iron core of existing solenoid valve is to make of the little permeability magnetic material of remanent magnetism, so that after magnetic field diminishes, remanent magnetism minimum on it is in order to the whereabouts of moving core.The utility model is but acted in a diametrically opposite way, and has designed a fixed iron core that is made of permanent magnet and concentrating flux sleeve, and its effect is to preset a permanent magnetic field.When coil adds positive voltage, suppose that the magnetic field of its generation is consistent with permanent magnetic direction, then the magnetic attraction that is applied of moving core upwards causes valve opening.After the outage, because the effect in permanent magnetic field, moving core is still held, and remains on the upper end, and valve is held open.When adding negative voltage, the magnetic field that coil produced is opposite with the direction in permanent magnetic field, and moving core causes valve closing owing to magnetic repulsion falls.After the outage, because the elastic force of spring and the gravity of moving core make valve continue to keep closing.Therefore, this solenoid valve will open or cut out because of the difference of the polarity of voltage that applies on the coil, behind the loss of voltage that is applied, still keep former on off state.So for a change its on off state only needs pulse signal to drive, so be named as impulse electromagnetic valve.The most outstanding advantage of impulse electromagnetic valve is to drive with pulse signal, thereby power consumption is very little, does not generate heat, and noiseless can continuously be moved, and has improved the reliability of solenoid valve.In addition, again can be in very low drive pulse signal (as 3V) work down.
Below, in conjunction with the accompanying drawings, the utility model is elaborated.
Accompanying drawing is a structural representation of the present utility model.By coil (3), concentrating flux sleeve (4) yoke (6), permanent magnet (7), moving core (pilot valve valve plug) (8), spring (5), separation sleeve (9), main valve valve plug (1), main valve valve seat (valve) (10) coil rack compositions such as (2).Permanent magnet (7) and concentrating flux sleeve (4) constitute the fixed iron core of this solenoid valve.
As an embodiment, add the pulse signal of certain pulsewidth at coil (3), suppose that the direction in the magnetic field of its generation and permanent magnetic field is consistent, then the magnetic attraction that is applied of moving core (8) upwards, open pilot valve, under the effect of hydrodynamic pressure, main valve valve seat (valve) (10) is opened.After pulse disappeared, because the effect of permanent magnet (7) and concentrating flux sleeve (4), moving core was still held, and remains on the upper end of separation sleeve (9), makes main valve still keep opening state.When coil (3) adds the undershoot of certain pulsewidth, the magnetic field that it produced is opposite with the direction in permanent magnetic field, and moving core falls because of magnetic repulsion, and pilot valve cuts out, and under the effect of hydrodynamic pressure, main valve valve seat (valve) is closed.Pulse because of the elastic force of spring (5) and the gravity of moving core (8), makes main valve continue to close after disappearing.Therefore, the unlatching of this impulse electromagnetic valve or close is with the change that changes to of executing pulse polarity outward, when outside execute pulse and disappear after, still keep its former on off state.Be suitable in the inlet valve of automatic washing machine and the automatic control process switch valve as fluid.
