Abstract
An adjustable water valve of time-controlled type consists of an inner shell and a time-controlled apparatus. The time-controlled apparatus is disposed inside the inner shell and includes an elastomer and a push rod. The elastomer is disposed between a support lid and the push rod. When the push rod is pushed into the inner shell, the water valve is opened, so the user can wash with the water ejected. After certain time, the water pressures are balanced and the elastomer which has been compressed will push the push rod back to its initial position to close the valve.
