Description
Technical field
The invention belongs to Solenoid Valve Technology field, and in particular to a kind of electromagnetism valve follower drive mechanism of anti-intensive magnetism attack.
Background technology
In shower, drinking water etc. using the occasion of solenoid valve control, can typically be related to charge, magnetic valve after user pays dues
Open, can just commonly use water, without taking or closed electromagnetic valve during arrearage, forbid using water.Current electromagnetism valve follower driving principle is electricity
Magnetic coil is fixed, and when the coil is energized, produces magnetic field, inhales moving armature, drives pushrod movement, opens valve opening, when the coil is de-energized,
Armature promotes push rod to reset under the action of the spring, close valve orifice.
Knowable to its principle, when outside has magnetic field, if magnetic field intensity inhales moving armature enough, you can open magnetic valve,
So as to destroy charging logic, realize without expense water, economic loss is brought to payment collector.
The content of the invention
For above-mentioned the deficiencies in the prior art, the present invention is intended to provide a kind of electromagnetism valve follower driving machine of anti-intensive magnetism attack
Structure, can effectively prevent the valve opening abnormal opening in the case where strong external magnetic field is disturbed.
To achieve these goals, the present invention uses following technical scheme：
A kind of electromagnetism valve follower drive mechanism of anti-intensive magnetism attack, including housing, are fixed with permanent magnet on housing, be provided with housing
Magnet coil, push rod and iron core, magnet coil are made up of coil rack and the wire being wound on coil rack, wire coiling direction
It is principle to be produced during being powered with the attracting magnetic field of permanent magnet, and coil rack is provided with through hole along its axis direction, and through hole top connects
Spring is connected to, spring end is connected with housing, and spring is fixed between case top and magnet coil, iron core is located in through hole,
In on iron core, core ends are fixedly connected with the casing spring overcoat, and coil rack is connected with push rod.
The axis direction of permanent magnet N, S poles is vertical with the section of magnet coil, axis direction and the magnet coil of iron core
Section is vertical.
Described coil rack and the material of push rod are non-magnet material.
By above technical scheme, beneficial effects of the present invention are：The electromagnetism of the prevented intensive magnetism attack that the present invention is provided
Valve follower drive mechanism, reasonable in design, permanent magnet and iron core are fixed on housing, with magnet coil as movable part band
Dynamic pushrod movement, and magnet coil and push rod are non-magnet material, are unaffected by the magnetic field, therefore in magnet coil no power
When, the magnetic field of any outside cannot make pushrod movement, can effectively prevent the valve opening abnormal opening under outside strong magnetic disturbance.
Brief description of the drawings
Fig. 1 is schematic diagram of the invention.
Fig. 2 is the schematic diagram of application of the present invention on pilot film type magnetic valve.
Specific embodiment
As shown in Figure 1, a kind of electromagnetism valve follower drive mechanism of anti-intensive magnetism attack, including housing 1, it is fixed on housing 1
Have and magnet coil 2, push rod 4 and iron core 6 are provided with permanent magnet 7, housing 1, magnet coil 2 is by coil rack 3 and is wound on coil bone
Wire composition on frame 3, it is principle, the edge of coil rack 3 to be produced when wire coiling direction is to be powered with the attracting magnetic field of permanent magnet
Its axis direction is provided with through hole, and through hole top is connected with spring 5, and the end of spring 5 is connected with housing 1, and spring 5 is fixed on housing 1
Between top and magnet coil 2, iron core 6 is located in through hole, and spring 5 is coated on iron core, and the end of iron core 6 is fixed with housing 1 and connected
Connect, coil rack 3 is connected with push rod 4, when magnet coil 2 is powered, produce and the attracting magnetic field of permanent magnet 7, in the suction of permanent magnet 7
Under gravitation, magnet coil 2 is moved to the direction of permanent magnet 7, while drive push rod 4 to move together, spring-compressed.
The axis direction of permanent magnet 7N, S poles is vertical with the section of magnet coil 2, and the magnetic direction of permanent magnet 7 is with electromagnetic wire
The magnetic direction that circle 2 is produced when being powered is consistent, because permanent magnet 7 is fixed on housing 1, therefore permanent magnetism after the energization of magnet coil 2
Iron 7 can attract magnet coil 2 to move upwards, and the axis direction of iron core is vertical with the section of magnet coil, plays reinforcement magnetic force
Effect.
The material of coil rack 3 and push rod 4 is non-magnet material, prevents the attack in various magnetic fields.
In order to technical scheme is explained further, the present invention is explained in detail below by specific embodiment
State.
As shown in Figure 2, when magnet coil 2 is powered, a magnetic field is produced, with the phase of permanent magnet 7 being fixed on cover plate 8
Mutually attract, drive push rod 4 to be moved along the axial direction of iron core 6, while spring 5 compresses, open the pilot hole on cut-off diaphragm 9, it
Whole cut-off diaphragm 9 is moved upwards under hydraulic pressure effect afterwards, and the valve opening on valve body 10 is opened；When magnet coil 2 is powered off, in bullet
Under spring 5 is acted on, magnet coil 2 drives the counter motion of push rod 4, the pilot hole on closing switch diaphragm 9, afterwards under hydraulic pressure effect
Whole cut-off diaphragm 9 is moved downward closes the valve opening on valve body 10, due to being that magnet coil drives push rod as movable part
The opening and closing of valve opening are moved and then realize, and the material of magnet coil and push rod is not influenceed by magnetic field, therefore, work as electromagnetism
During coil blackout, even if outside also will not produce influence in the presence of stronger magnetic field on system.
And in the prior art, the operation principle of magnetic valve is fixed for magnet coil, when the coil is energized, magnetic field is produced, inhaled
Moving armature, drives pushrod movement, opens valve opening, and when the coil is de-energized, armature promotes push rod to reset under the action of the spring, shutoff valve
Hole；Knowable to its principle, its movable part is armature, when there is malice magnetic field in outside, if magnetic field intensity inhales moving armature enough,
Magnetic valve can be opened, so as to cause economic loss to user.
In sum, the present invention can normally realize opening and the closing of magnetic valve, and due to driving the movable part of push rod
It is without any material affected by magnetic fields, it is possible to effectively prevent various magnetic from attacking, protect user benefit.
Above-described is only the preferred embodiment of the present invention, it is noted that for a person skilled in the art,
Under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as of the invention
Protection domain.
