Description
The utility model relates to a kind of solenoid valve, belongs to the electronic technology application technical field.
Existing solenoid valve has purposes widely in automatic control of fluid and remote control field, but its power consumption is more, the coil easy burn-out.Though mechanical self-latching type impulse electromagnetic valve little power consumption, the self-locking device more complicated, fragile, two kinds of all difficult fluid and electric parts realized of solenoid valve are isolated fully.
The purpose of this utility model provides a kind of simple in structure, economize on electricity, material saving, robust fluid and electrical isolation, and actuating length is big, it is unimpeded to be beneficial to fluid, and can conveniently transform the novel impulse electromagnetic valve of general solenoid valve.
The purpose of this utility model realizes by following technical measures:
The novel impulse electromagnetic valve of forming by coil, quiet iron, spring, moving iron and spool, be provided with permanent magnet, shielding can and controller in the solenoid valve, permanent magnet is fixed on Jing Tieshang, and shielding can is between spring, moving iron, spool and coil, quiet iron, permanent magnet, and controller is connected with coil.
Controller is made up of key switch A, B and power supply, and the end of key switch A and B is connected with the positive source key, and the other end is connected with coil, and the centre tap of coil is connected with the negative pole of power supply.
Controller also can be made up of commutator, electric capacity and power supply, and the C end of commutator is connected with an end of coil by capacitor, and the D end of commutator is connected with the positive pole of power supply, and the E end of commutator is connected with the negative pole of power supply and the other end of coil.
Controller also can be made up of an impulse circuit, and the output terminal of impulse circuit is connected with the two ends of coil.
In the use, when controller when coil provides a forward current, the magnetic direction that quiet iron produced and the magnetic direction of permanent magnet in the same way, two magnetic field superposition strengthen the suction of moving iron, moving iron adhesive drives spool and opens; The suction of permanent magnet makes iron keep attracting state after the current vanishes.When controller when coil provides a back current, the magnetic direction that quiet iron produced and the magnetic direction of permanent magnet are reverse, two magnetic field cancellation lose the adhesive to moving iron, under the effect of spring, moving iron discharges, and drives spool and closes.Shielding can has fluid and electrical equipment isolation and moves the iron leading role.
The utility model is sturdy and durable, and is simple in structure, has fluid and the isolated and tangible power savings of electrical equipment.
