PURPOSE: An electric water valve is provided to reduce the total length of a flexible joint by inserting a joint tube connected to a piping into the outlet side of the body and by using a rubber packing. CONSTITUTION: An electric water valve includes a body(10), a disc(20), a screw axis(30), a joint tube(40), a rubber packing(50) and a fixing unit(60). The flange(12) is formed in entrance and exit of the body. The disc settling unit(11) is formed in the upper side of the body. The insertion hole(13) is formed in the outlet side inner circumference. The disc controls fluid by opening and closing up and down. The screw axis is connected to the upper side of disc and drives the disc to the top and bottom. The joint tube is connected between the body and piping and absorbs vibration and expansion. The rubber packing shuts tight the insertion hole of the body and outer circumference of the joint tube. The fixing unit prevents from the rubber packing being deviated to one side.
