Solenoid valve

The utility model relates to the technical field of valves, in particular to an electromagnetic valve which comprises a static iron core and a movable iron core, the surface, close to the static iron core, of the movable iron core is provided with a concave part, the movable iron core is provided with a first position and a second position, a gap is formed between the movable iron core and the static iron core at the first position, and an elastic piece is arranged in the gap. At least part of the elastic piece is located in the concave part, and at the first position, a gap is formed between one end, close to the static iron core, of the elastic piece and the static iron core; the movable iron core is attracted with the static iron core at the second position, so that the elastic piece is elastically deformed, and the elastic piece is completely located in the concave part. When the movable iron core is about to be in contact with the static iron core, the elastic piece can effectively slow down the moving s
