Abstract:
According to the working principle and structural characteristics of the magnetic latching valve, the armature is always at the eccentric state.Under the action of permanent magnet field, the armature contacts with the valve body guide surface, increasing the friction between the armature and the valve body, resulting in the operating life of the magnetic latching valve shorter than that of the direct-acting solenoid valve.This paper mainly studies the influence of centering of magnetic latching valve armature on static suction.Firstly, the working principle and magnetic circuit design characteristics of magnetic latching valve were expounded.Then, under the condition of complete centering of armature, the mathematical model of magnetic circuit segmentation method and the finite element simulation model of magnetic field of magnetic latching valve were established and compared, and the static electromagnetic force of armature was calculated.Finally, the position of the armature was changed to make the armature at an eccentric state.The static electromagnetic force under different eccentricity was obtained by simulation, and the influence law was obtained by combining the change of the magnetic induction intensity on the surface of the armature.The results show that the armature will be affected by the lateral magnetic force along the radial direction that the lateral permanent magnetic force generated by the permanent magnet or the lateral electromagnetic force generated by the coil.The lateral magnetic force increases rapidly with the increase of eccentricity.The process of depositing non-metallic film on the surface of the armature can adjust to the centering, effectively reduce the lateral magnetic force and prolong the operation life of the magnetic latching valve.
