Abstract
A double flow control mechanism of a soft touch drain valve and a double flow control method, includes a base, a float component and a starting component. The base is assembled with a valve body. The float component is has a flowing passage and can move relative to the base to open and close the drainage opening. The flowing passage connects the inside and the outside of the float chamber of the float component. The starting component controls the size of the flowing passage. The first starting switch can open a smaller flowing passage of the float component; the resultant force drains a first drainage volume of water. The second starting switch can open a larger flowing passage of the float component; the resultant force drains a second drainage volume of water.
