The present invention relates to an electromagnetic coil circuit which comprises a switch connected with a power source loop and an electromagnetic coil L. The electromagnetic coil circuit is characterized in that the power source loop is sequentially connected with a diode D in series and connected with an electrolytic capacitor C in parallel to form a charging circuit; the charging circuit is connected with a branch circuit which comprises a resistance and a triode T1 in parallel; the branch circuit is connected with an electromagnetic coil L and an electromagnetic coil circuit of a MOS tube T2 in parallel, wherein the resistance comprises a pair of parallel resistance R1 and R2 which are connected in parallel, and one end of the MOS tube T2 is connected between the resistance R2 and the triode T1. In the energizing process, the current in the whole circuit is the current which is only required for triode bias, and the electromagnetic coil can not generate power consumption, thus the coil can not be burnt out because of heating. The electromagnetic coil circuit has simple structure, and the volume of the electromagnetic coil is smaller than that of other normally closed coils of low power consumption.
Description
Technical field
The present invention relates to a kind of solenoid, particularly a kind of is the electromagnetic shut-off valve solenoid of actuating signal with outage or single low level pulse.
Background technology
Present domestic outage is closed with the solenoid of electromagnetic shut-off valve of a great variety, the principle of using also is varied, the high shortcoming of enamelled wire caloric value but the power consumption when all ubiquity does not cut off the power supply on the inner enamelled wire of solenoid is switched on more greatly, for a long time, though have some manufacturers to release the low-power consumption solenoid, have the big and more high factor that is unfavorable for that enterprise controls cost of cost of solenoid internal circuit more complicated, volume.
Summary of the invention
In order to overcome the deficiency of existing solenoid, the invention provides a kind of electromagnetic coil circuit, solve the traditional electrical magnetic coil power consumption high technical problem of enamelled wire caloric value of switching on too greatly, for a long time.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of electromagnetic coil circuit, comprise the switch and the solenoid L that are connected with electric power loop, it is characterized in that: be in series with a diode D on the electric power loop successively, be parallel with an electrochemical capacitor C, form charging circuit, in parallel with above-mentioned charging circuit one by resistance and triode T

Basic thought of the present invention is: by energy-storage travelling wave tube storage of electrical energy when the operate as normal, and when the needs electromagnetic shut-off valve is moved, to solenoid, utilize the solenoid acting to produce the required electromagnetic force of mechanical action the electric energy abrupt release.
The present invention is a kind of lower calorific value, the electromagnetic coil circuit of direct current supply closed type cheaply, be a kind of with the outage or single low level pulse be the electromagnetic shut-off valve electromagnetic coil circuit of actuating signal, its beneficial effect is as follows:
1, the present invention is in galvanization, and the electric current in the entire circuit is the triode required electric current of setovering, and does not produce power consumption on the solenoid, so can not cause coil burnout because of heating.
2, solenoid can be an actuating signal with outage, has improved the fail safe of using.
3, when electromagnetic shut-off valve is moved, only produce the power of moment on the solenoid, owing to only in the very short time of capacitor discharge, have electric current to flow through on the solenoid, so the power consumption of solenoid is very little, save electric energy more, situations such as heating can not occur, can not exert an influence solenoid.
4, circuit structure is simple, and winding volume is little than other closed type low-power consumption winding volume.
