摘要： The present invention discloses a solenoid valve for water capable of enhancing a electromagnetic suction force and an implementation method thereof, the method comprises: obtaining a plastic-sealed stator assembly by injectiing plastic on a stator assembly, the plastic-sealed stator assembly; assembling the plastic-sealed stator assembly and a valve body assembly comprising a movable iron core together to form the solenoid valve for water;wherein the upper end face of the movable iron core at the initial position is set as not lower than the upper edge of lower magnetic conductive inner sleeve and not higher than 1/4 of the distance from the upper edge of lower magnetic conductive inner sleeve to the lower edge of upper magnetic conductive inner sleeve, so as to enhance the electromagnetic suction force of the solenoid valve for water. The plastic-sealed stator assembly comprises a coil assembly; an upper magnetic conductive inner sleeve and a lower magnetic conductive inner sleeve mounted in a hole of the coil assembly; a water-isolating sleeve located inside the upper magnetic conductive inner sleeve and the lower magnetic conductive inner sleeve; a yoke located outside the coil assembly and connecting the upper magnetic conductive inner sleeves and the lower magnetic conductive inner sleeves; a magnetic conductive seat mounted on an inner side of the water-isolating sleeve; and a plastic-sealed layer covering the coil assembly and the yoke.
