The invention relates to an automatic pass water valve. Its characteristics are: at the top of the valve body has the organization that can move the valve pole up and down to carry out a switch of valve. When the bottom of the arm is transferred to the other side of electromagnetic coil H Core on, is absorbed by the electromagnet, at this time the upper arm driven connecting pole, the valve pole and its bottoms to carry to go together with of press to rise already opened the valve door the water supply to the water tank; At the same time the upper arm has already will often open the switch K to shut to match, the electric circuit enters the working appearance. When the water tank overflows with a water pipe , in electrode go together with electrode T1, T2 is led by the water, add the electric voltage of the cathode of the power supply to one-way can control a pole of silicon , make one-way controlled the silicon drive trigger to lead, at this time, the electromagnetism coil H electricity produce the opposite direction with the magnetic field, the dint arm is vacuum force by the magnetic field to descend, the dint arm reset under the function of the spring coil elasticity, automatic pass water of a close of valve realization. Assigned to the indoor valve, easy to operate, long service life, the opening and closing reliable.
