The utility model relates to a bistable two-position three-way pulse-control magnet valve, which comprises a valve body part, a set of permanent magnets with repulsive polarity arranged outside the middle of the valve body part, a magnetizing coil for covering the valve body part and the permanent magnets outside, a magnetic yoke frame for fixing and arranging, a set of permanent magnet mounting frames for the arrangement of the permanent magnets, and a fixing plate and a protection cover for mounting and fixing. The utility model is characterized in that the valve body part comprises an H-shaped valve body housing; a round-hole sliding trench is arranged in the middle part of the valve body housing, a valve core is arranged in the round-hole sliding trench, a single-tube component and a double-tube component are arranged in the axial direction on the left and right sides of the valve body housing respectively, and a first valve communicated with the double-tube component and a second valve communicated with the single-tube component are arranged on the two ends of the round-hole sliding trench respectively. With a direction-changing buffering cushion added, the utility model assumes direction-changing and non-electric self-locking functions, and also the direction-changing noise of the magnet valve is reduced and the sealing is improved, thereby creating the stable working state and the prolonged service life.
