Abstract: A high-power bi-directional non-recovery spring magnetic valve including permanent magnets has an upper magnetic circuit part and lower magnetic circuit part symmetrically disposed and connected together via an armature connection rod and a housing connection ring, the upper magnetic circuit part comprises an upper iron core, an upper housing, an upper coil, an upper annular permanent magnet, an upper yoke iron and an upper push rod, the lower magnetic circuit part comprises a lower iron core, a lower housing, a lower coil, a lower annular permanent magnet, a lower yoke iron and a lower push rod. The magnetic valve comprising permanent magnets realizes bistable-state magnetic retaining, and has an adjustable retaining force for permanent magnet adjustment, quick response, and high output force.
