阅读说明：本技术 一种电子膨胀阀 (Electronic expansion valve ) 是由 不公告发明人 于 2020-06-28 设计创作，主要内容包括：一种电膨胀阀,该阀针丝杆组件(1)还包括外缘导向段(16),该电子膨胀阀包括与该外缘导向段(16)配合的内缘导向段(12A),该电子膨胀阀其阀针(11)在动作过程中,阀针丝杆组件(1)的外缘导向段(16)与电子膨胀阀的内缘导向段(12A)相配合,为阀针(11)提供导向,相对减少了阀针(11)相对于阀口出现偏斜的情况,从而减少了阀针出现偏心磨损的情况。(An electric expansion valve, the valve needle screw rod assembly (1) also includes the outer edge guide section (16), the electric expansion valve includes the inner edge guide section (12A) matching with the outer edge guide section (16), the outer edge guide section (16) of the valve needle screw rod assembly (1) matches with the inner edge guide section (12A) of the electric expansion valve in the action process of the valve needle (11) of the electric expansion valve, which provides guidance for the valve needle (11), relatively reduces the deflection of the valve needle (11) relative to the valve port, thus reducing the eccentric wear of the valve needle.)
