Technical field
The present invention relates to a kind of freezing, cold storage refrigerator dynamoelectric switching valve.
Background technique
Small refrigeration systems is used for freezing, the cold storage refrigerator of double temperature double control with two-position three way magnetic valve (standard No. is JB/T7223-1994), application 1 more than 0 year at home, this solenoid valve as shown in Figure 8:
It has an import d1 and two outlets d2, d5;
Solenoid valve has an outlet d2 to be in normally off when the no electric circuit state, and another outlet d5 is in normally open, after the solenoid valve energising, often leaves a mouthful d5 and closes, and normally closed outlet d2 opens, by the open and-shut mode of power on/off switching solenoid valve two outlets;
The open and-shut mode of electromagnetic valve outlet is to realize its function by the working position of control electromagnetic valve spool d4, the no electric circuit state, spool d4 is in a working position under the effect of spring d6, close normally closed outlet, and another outlet is in normally open, after the coil d3 energising, electromagnetic force drives the pressure difference active force that spool overcomes spring force and air pressure, and spool moves to another working position, when this working position, normally closed outer pipe is opened, and often drives outer pipe and closes;
The driving mode of valve core of the electromagnetic valve is the direct drive-type of electromagnetic force, and spool moved with two end valve seats and directly clashes into when power on/off was switched, and can produce heavier Strike note in the handoff procedure;
Solenoid valve has a kind of working state to switch on always, arrives 4-6W though reduce the power consumption of solenoid valve as far as possible, and in actual use, the energy consumption of solenoid valve still accounts for the 4-6% of energy consumption of refrigerator.
