Abstract
An electronic expansion valve is provided, a stop component thereof includes a spindle which is fixed with respect to the valve seat, a spring guide rail sleeved on the spindle, and a sliding ring configured to cooperate with the spring guide rail; one end of the sliding ring extends to form a stop rod, and a top of the magnet is provided with a stop hole, the stop rod passes through the stop hole, and when the sliding ring is at an upper limit position and a lower limit position, the stop rod remains in the stop hole. The structural design of the electronic expansion valve may reduce a number of components, simplify the assembly process of a stop rod, and improve the operational reliability of the stop rod, and reduce a radial dimension of a magnet, thereby saving the material cost and realizing the minimization of the product.
