Abstract
A flow control valve includes a valve body, a control member and a cover. The valve body has a receiving space, a resting face, a stepped face, a positioning groove and a plurality of water outlet holes. The control member is provided with an elastic portion, a sealing portion and an abutting face. When a flow pressure of the fluid is under a normal condition, the elastic portion of the control member is contracted inward, so that the abutting face of the control member is disposed at an open state. When the flow pressure of the fluid is under an abnormal condition, the elastic portion is expanded outward and abuts the stepped face of the valve body, so that the abutting face of the control member abuts the resting face of the valve body, to seal the water outlet holes of the valve body.
