Abstract: Provided is an electronic expansion valve, the valve needle screw assembly (1) also includes an outer edge guide section (16), the electronic expansion valve includes an inner edge guide section (12A) matched with the outer edge guide section (16), in the process of the action of the valve needle (11) of the electronic expansion valve, the outer edge guide section (16) of the valve needle screw assembly (1) is matched with the inner edge guide section (12A) of the electronic expansion valve, to provide the guide for the valve needle (11), relatively reducing the deviation of the valve needle (11) relative to the valve port, thereby reducing the eccentric wear of the valve needle.
