The sliding sleeve 40 abuts against the diaphragm 20, and at the same time pushes the magnet 60 by the elastic action of the elastic member 80, so that the magnet 60 maintains a sustained pushing force against the diaphragm 20, and makes The convex portion 61 is locked in the pressure releasing hole 21, so that the diaphragm 20 can close the water outlet passage 12, and the water inlet passage 11 and the water outlet passage 12 are not in communication.

At this time, the electromagnetic device 70 can be powered off, and the convex portion 61 of the magnet 60 and the pressure releasing hole 21 can maintain an appropriate pressure relief distance, so that The control passage 13 communicates with the water outlet passage 12 through the pressure relief hole 21, so that the water pressure formed in the control passage 13 is discharged to the water outlet passage 12 through the pressure relief holes 21 through the pressure relief holes 21, thereby The diaphragm 20 is caused to have a pressure difference on the side of the water inlet passage 11 and the side of the control passage 13, so that the diaphragm 20 is displaced by the water pressure of the water inlet passage 11 and displaced in a direction away from the through hole 14.

When the magnet 60 is magnetically attracted by the magnetic conductive block 43, the convex portion 61 of the magnet 60 forms an appropriate pressure relief distance with the pressure releasing hole 21, and the diaphragm 20 is The sliding sleeve 40 is displaced in the direction away from the through hole 14 by the water pressure of the water inlet passage 11, and the magnetic attraction force of the magnet 60 is offset by the reverse magnetic field, and is elasticized by the elastic member 80. Pushing away from the magnetic block 43, And further, the diaphragm 20 is displaced, and the convex portion 61 of the magnet 60 is pushed against the pressure release hole 21 to be closed. At this time, the control passage 13 will continue to receive the water inlet passage 11 from the pressure inlet hole 22 . The pressure is applied to the diaphragm 20 to close the through hole 14, and the diaphragm 20 can interlock the movement of the sliding sleeve 40, so that the improvement of the electromagnetic control water valve can utilize the elastic effect of the elastic member 80. The elastic force of the magnet 60 is continuously pushed against the diaphragm 60, and the magnet 60 is continuously pressed against the diaphragm 20, and the convex portion 61 is locked in the pressure release hole 21, so that the diaphragm 20 is continuously closed.
