| description | An electronic expansion valve includes a valve needle screw assembly which includes a valve needle, a valve needle sleeve, a washer part, a spring, and a screw assembly. The valve needle sleeve includes a circumferential wall part and a fitting part. The inner diameter of the fitting part is smaller than the inner diameter of the circumferential wall part. The screw assembly includes a lower stopper part, a valve needle support part, and an upper stopper part. The lower stopper part abuts against the washer part. The valve needle support part abuts against the fitting part of the valve needle sleeve. The upper stopper part abuts against the spring. The distance between the valve needle support part and the washer part is D1; the distance between the valve needle support part and the upper end of the fitting part is D2; and D1≥D2. |
