Abstract:

Discharge characteristic of the cone valve structure is studied. Based on this, a new structure of electronic expansion valve (EEV) is proposed. The new structure can improve discharge characteristics. It also has some additional merits including low leakage and good linearity. All these provide a platform to control flux accurately. It is useful in improving performance of air conditioning systems.

Key words: electronic expansion valve, flow control, valve shuttered structure
