Abstract
A two-way flow control valve includes a valve body, a control member, a cover mounted and a gasket. The valve body has a first water hole, a plurality of first ribs and a plurality of first flanges. The cover has a second water hole, a plurality of second ribs and a plurality of second flanges. The control member has a passage. The control member is provided with two V-shaped inclined planes which are clamped respectively by the first flanges of the valve body and the second flanges of the cover. When the water passing through the two-way flow control valve is large enough to reach a determined value, the control member is stretched and deformed to reduce the diameter of the passage, and to partially block the first water hole of the valve body or the second water hole of the cover.
