Direct driving type electromagnetic permanent-magnet water valve

The utility model relates to a direct driving type electromagnetic permanent-magnet water valve. The utility model is composed of an upper and a lower valve seats, a valve body, a valve core, a coil, a housing, etc.; the upper end and the lower end of the inner cavity of the valve body are connected with the hollow upper valve seat and the hollow lower valve seat by screw thread buckles, the upper end and the lower end of the column surface of the valve body are respectively wound with a coil, and the valve body is provided with a spool which is provided with a permanent magnet; the utility model achieve self locking by the permanent magnet after action, which is safe and reliable in operation. The utility model has the action of water magnetization and can reduce obviously the scale incrustation and rust in a water tube (or a water tank); besides, the utility model has the advantages of light weight small size, simple processing technology, low cost, long service life, large water flow, etc.
