Abstract
An electronic expansion valve is provided, the valve needle component thereof is provided with an axial mounting hole, the screw rod position limiting portion is mounted at the bottom end of the screw rod and extends into the axial mounting hole, and the valve needle position limiting portion is mounted at an open end of the axial mounting hole; and a distance between the bottom end of the screw rod and a bottom wall of the axial mounting hole forms the predetermined buffer distance. When the refrigerant flows reversely, the structural design of the electronic expansion valve may, on one hand, simplify the control procedure, and on the other hand, avoid the problem that a screw rod is stuck because a valve needle component is not removed in time.
