Description of drawings
Fig. 1 is the structured flowchart of the utility model washing unit.
Embodiment
Referring to Fig. 1; In the washing unit of a kind of motor OCV of the utility model valve; First power supply is connected with governor circuit, is used to provide power supply signal, and governor circuit is programmable logic controller (PLC) (PLC); Between the governor circuit and first power supply, be provided with control switch, can make things convenient for the startup of whole governor circuit.
Be provided with ac power supply circuit breaker (circuit breaker among the figure) between first power supply and the control switch, when making governor circuit short circuit or governor circuit overload because of accidental cause, circuit breaker will break off in 0.3 second, thus the protection governor circuit.
Governor circuit is provided with the self check tutorial light, after the control switch closure, and the governor circuit POST, the normal rear indicator light of self check can be lighted, the prompting user.
Governor circuit is connected with reset switch and input unit, and reset switch adopts the touch-type switch, and input unit adopts some touch-type switches, the input that is used to instruct.
The OCV valve is at least two; OCV valve cell in promptly scheming; Be provided with the solid-state relay unit, wherein have and the some one to one solid-state relays of OCV valve (the following relay that also is called for short), the control signal of relay is from governor circuit; Be provided with the first fusing insurance between the control signal input end for governor circuit and relay, can when overburdening, protect circuit.
Second source is used for to the power supply of OCV valve, and the output terminal of relay is connected between OCV valve and the second source, i.e. all corresponding OCV valve of control of each relay.
Be provided with the second fusing insurance between the output terminal of second source and relay, can when the working circuit overburdening of OCV valve, carry out power-off protection.Also be provided with the standby power supply that links to each other with second source, the output terminal of this standby power supply inserts in the working circuit of OCV valve, when second source lost efficacy, starts standby power supply, to guarantee the proper functioning of OCV valve.
The utility model washing unit working procedure is following:
