OVERVIEW:
DPF electronic expansion valve is a kind of promising throttling device suited for the mechano-electronic demands of refrigeration system. It can give fast response and a wide modulating range. And moreover, it can work under the preset modulating method to achieve the excellent quality of superheat modulation. So it make the refrigeration system work efficiently and steadily, and make controlled temperature accurately; It used widely in refrigeration system such as inverter air conditioner.
WORKING PRINCIPLE:
When the inputting voltage pluses are applied to the coil in determined sequence, a rotational magnetic field is produced. Thus the rotor, which is made of permanent magnetic material, is rotated by the magnetic torque, making the valve pin up or down through the transmitting structure, nad to change the mass flow area of valve. In this way, the mass flow can be adjusted automatically to ensure that the system is kept in the best state.
