Electromagnetic double-sided sealing valve

The invention relates to an electromagnetic double-sided sealing valve, which comprises a valve body internally provided with two channels and corresponding openings; a valve plate moveably and vertically inserted between two channels, and provided with a valve rod extending out of the valve body; two compressing pieces which are circular and respectively arranged at inner ends of two channels of the valve body, wherein one compressing piece is uniformly provided with a permanent magnet or a non-oriented silicon sheet along the peripheral direction. A lead connected with a power supply is winded on the silicon sheet to form an electromagnet. The other compressing piece is uniformly provided with the non-oriented silicon sheet along the peripheral direction. The lead connected with a power supply is wound on the silicon sheet to form an electromagnet. The opening direction of the permanent magnet corresponds to the direction of the valve plate. According to the invention, a switch valve can be switched accordi
