The utility model relates to an electromagnetic valve with buffer structure, which comprises a valve shell, an electromagnet assembly, which is characterized in that the upper end of the valve shell is arranged on the shaft can move up and down, with the cavity axis, the axis is arranged on the upper end of the end cover, shaft are fixed at the lower end of the armature arranged on the end cover; it can move up and down the stem cavity, the lower end of the valve rod is arranged in the shaft, the upper end of the valve rod is fixed with a spring seat; the shaft sleeve is provided with a first spring, the first spring of the upper and lower ends are respectively abutted on the spring seat and the valve shell; the cavity axis is provided with second spring second spring, the upper and lower ends respectively. Against the lower end of the valve rod and the cavity bottom, elastic coefficient and elasticity coefficient is less than second of the first spring spring. Face contact on the core when the internal armature and electromagnet, such as to promote stem second, at this time the spring cushion, the stem can still continue to drive a long distance, so the solenoid valve in a range of travel can work normally, to ensure the reliability of the electromagnetic valve used.
