Abstract
An electronic expansion valve and an assembly method therefor. The electronic expansion valve includes a screw rod component, a movable connection component, a valve pin component and an elastic element. One end of the elastic element abuts the movable connection component, and the other end thereof abuts the valve pin component. In the period from the valve pin component closing the valve port part to the screw rod component moving a pre-set displacement amount in the valve closing direction, the elastic element does not generate an elastic force pushing the valve pin component towards the valve port part; and in the period from the valve pin component closing the valve port part to in a case that the screw rod component moving more than the pre-set displacement amount in the valve closing direction, the elastic element generates an elastic force pushing the valve pin component towards the valve port part.
