Description

Magnetic-holding electric magnet
The utility model relates to a kind of magnetic-holding electric magnet that is applicable to electromagnetically operated valve and the moving final controlling element of electromagnetism.
Operate condition commonly used at present keeps electromagnet that following a few class is arranged:
One, "on" position keeps electromagnet.This class electromagnet divides two kinds again, and a kind of is that the energising attracting state keeps, and another kind is that energising release state keeps.These two kinds of electromagnet will keep operate condition, all want the hold-in winding energising, in case outage just can not keep operate condition.The electromagnet of this hold mode, big with electrical power consumed, the easy heating burnout of coil, the coil cost is also higher.
Two, machine performance keeps electromagnet.This class electromagnet is the operate condition that keeps electromagnet by mechanical structure.Whole electromagnet is synthetic by two groups of electromagnet group, and a part is the action part of electromagnet, and another part is mechanical retaining part.Two groups of electromagnet respectively have coil and magnetic structure, and this electromagnet structure more complicated, cost height, volume is big, failure rate is high.
The purpose of this utility model provides a kind of simple in structure, cost is low, failure rate is little and wasted work is little magnetic-holding electric magnet, and it keeps adhesive or release state when outage, when energising, changes adhesive and becomes the release state, or change and release into attracting state; Or when outage, use the hand gear adhesive.Keep attracting state, when energising, change attracting state and become the release state.
Above purpose is to be reached by following proposal: this magnetic-holding electric magnet comprises yoke, plunger tube, coil, moving iron core and spring, coil is contained in the shaped as frame yoke, coil and yoke are enclosed within plunger tube and place outward, spring is contained on the moving iron core, moving iron core is contained in the plunger tube and can moves up and down, inlay permanent-magnet steel in moving lower end unshakable in one's determination or on the plunger tube top, or be inlaid with the magnetic pole of annular permanent-magnet steel on the plunger tube top.When coil electricity, electric current flows into from coil one end, and when the pole polarity that electromagnetic circuit produces on moving iron core was consistent with the polarity of forever encircling steel, moving iron core was inhaled into plunger tube.When outage, by between permanent-magnet steel and the yoke or the maintenance of the magnetic attraction between permanent-magnet steel and moving iron core operate condition.When electric current flows into from the coil other end, when polarity that electromagnetic circuit produces on moving iron core and permanent-magnet steel were inconsistent, permanent-magnet steel and yoke no longer included suction.On moving iron core, two opposite polarity magneticactions are arranged, the one, the polarity that coil produces, another is the polarity that permanent-magnet steel produces, this two polarity is opposite, and is moving unshakable in one's determination under this two magneticaction, extrapolated to plunger tube.In addition, in above-mentioned magnetic-holding electric magnet, hand gear is equipped with on said moving top unshakable in one's determination in the top of passing plunger tube.When outage, use the hand gear adhesive, keep attracting state, when energising, change attracting state and become the release state.
