Abstract
The utility model which provides a double coil half wave rectification current flow exchange electromagnet comprises an electromagnet which comprises a stable iron core, a movable iron core and coils, and the coil comprises two coils 11,12, and one end of the coil 11 which is connected with one end of the coil 12 is connected with one end of a power supply, and the other end of the coil 11 is connected with the anode of a diode 13, and the other end of the coil 12 is connected with the cathode of a diode 14, and the anode of the diode 13 which is connected with the cathode of the diode 14 is connected with the other end of the power supply. The utility model which is compact in structure, low in cost, no noise, small in energy consumption is specifically suitable for valves.
Description
(1) technical field
The utility model relates to a kind of electromagnet.
(2) background technology
Electromagnet partly is made up of contact making device, quiet iron, armature, coil etc.Its sticking or disconnection are to be controlled by the energising of electromagnetic system, outage.Because electromagnetic system will consume certain electric energy during sticking, also can produce noise simultaneously.With the immediate background technology of the utility model be disclosed in the utility model patent file of ZL98201924.6 " T type segmented economize on electricity noiseless A.C. contactor ".It is to divide two sections adhesives by three coils, has one group of coil to be in off position after the adhesive, and travel switch will be arranged, therefore cause the waste of making complicated and copper cash, improved manufacturing cost, also aggravated the crowded of core window, particularly compact electromagnetic barred window mouth is very little, is difficult to make.
(3) summary of the invention
The purpose of this utility model is to provide a kind of compact conformation, with low cost, energy-conservation muting twin coil halfwave rectifier that the afterflow alternating electromagnet is arranged.The purpose of this utility model is achieved in that it comprises static iron core, moving iron core, coil, coil is made up of two coils 11,12, one end of coil 11,12 connects the back and is connected with an end of power supply, the other end of coil 11 links to each other with the negative pole of diode 13, the other end of coil 12 links to each other with the positive pole of diode 14, links to each other with the other end of power supply after the positive pole of diode 13 links to each other with the negative pole of diode 14.Form its sucking coil jointly by two coils in the device of the present utility model, two coils constitute the half-wave rectifying circuit of two parallel connections respectively.Coil 11 energisings during positive half wave, coil 12 energisings when bearing half-wave.And when two coil electricity electric currents descend, form afterflow, make the suction of iron core not have the zero passage place.Though so be alternating electromagnet, iron core does not have short-circuited conducting sleeve, noise is minimum.Its compact conformation, with low cost, energy consumption is less.Be particularly suitable for using on the valve.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an electrical block diagram of the present utility model.
(5) specific embodiments
For a more detailed description to the utility model for example below in conjunction with accompanying drawing: in conjunction with Fig. 1, the twin coil halfwave rectifier is by comprising static iron core 1, coil 3, moving iron core 6 forming of afterflow alternating electromagnet, coil is on skeleton 2, moving iron core is positioned at the middle part of static iron core, moving iron core is with plastic sleeve 4 outward, between the bottom of plastic sleeve and the moving iron core spring 5 is arranged.In conjunction with Fig. 2, coil is made up of two coils 11,12, one end of coil 11,12 connects the back and is connected with an end of power supply, the other end of coil 11 links to each other with the negative pole of diode 13, the other end of coil 12 links to each other with the positive pole of diode 14, links to each other with the other end of power supply after the positive pole of diode 13 links to each other with the negative pole of diode 14.Again in conjunction with Fig. 1, device of the present utility model combined with valve body 7 can form an electromagnetically operated valve.
Claims (1)
1, a kind of twin coil halfwave rectifier has the afterflow alternating electromagnet, it comprises the electromagnet of being made up of static iron core, moving iron core, coil, it is characterized in that: coil is made up of two coils (11), (12), one end of coil (11), (12) connects the back and is connected with an end of power supply, the other end of coil (11) links to each other with the negative pole of diode (13), the other end of coil (12) links to each other with the positive pole of diode (14), links to each other with the other end of power supply after the positive pole of diode (13) links to each other with the negative pole of diode (14).
