Abstract
The utility model discloses an AC/DC electromagnetic value, a flow-wheeling diode is connected in paralleled with the tow ends of the coil of the electromagnetic value, and connects with four diodes named 3, 4, 5, 6 to form bride rectifier, and the anode of the 3# diode and the 4# diode are paralleled and are connected with the anode of the 2# flow-wheel diode. The cathode of the 5# diode and the 6# diode that are connected in paralleled are connected with the anode of the 2# flow-wheel diode. Either AC or DC supplied, the polarity of both ends of the coil is unchanged, and can work normally.
Description
Technical field:
The utility model relates to a kind of solenoid valve.
Background technique:
According to the AC and DC of operating voltage, solenoid valve is divided into DC electromagnetic valve and alternating current electromagnetic valve at present, generally can not exchange between them.
The model utility content:
The utility model provides a kind of friendship, straight bi service electromagnetic valve at the problems referred to above.
The utility model is at the two ends of electromagnetic valve coil 1 fly-wheel diode 2 in parallel, also be connected with by diode 3,4,5,6 and constitute rectifier 7, and link with the negative pole of fly-wheel diode 2 after the negative pole parallel connection of described diode 3 and 4, diode 5 and 6 anodal and the positive pole that connects back and fly-wheel diode 2 link.
Adopt the technical program, because the existence of rectifier and fly-wheel diode, regardless of external circuit input polarity, the electromagnetic valve coil both end voltage is always fixing VDC, and promptly its polarity of voltage is constant all the time.Therefore no matter be DC electrical source or ac power supply, solenoid valve of the present utility model all can proper functioning.Certainly selected all diodes all should be able to bear circuit voltage.
Description of drawings:
Fig. 1 is an electrical schematic of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
At the two ends of the coil 1 of solenoid valve fly-wheel diode 2 in parallel, diode 3,4,5,6 constitutes rectifiers 7, and diode 3 and 4 back anodal in parallel link with the positive pole of fly-wheel diode 2, diode 5 and 6 negative pole link with the negative pole of fly-wheel diode 2 after in parallel.
Because the existence of rectifier 7 and fly-wheel diode 2, when electric current electrode input end during at the negative pole end of diode 4, negative input negative pole end at diode 3, diode 6,3 conductings, the coil 1 of solenoid valve gets electric, and its both end voltage polarity is opposite with the polarity of diode 2; When electric current negative input during, diode 5,4 conductings at the negative pole end of diode 4, electrode input end negative pole end at diode 3, the coil 1 of solenoid valve electric, its both end voltage polarity also polarity with diode 2 is opposite; Promptly, can not influence electromagnetic valve coil both end voltage polarity all the time, so the utility model becomes friendship, straight bi service electromagnetic valve regardless of the polarity of importing.
