The present invention relates to a valve with a hinged valve core. The valve comprises a valve body, a valve core, an operating mechanism, a motion-transferring device and a locking device. The valve body is a housing. The housing is formed with a operating hole used to partially accommodate the operating mechanism and a channel having an inlet and an outlet. The valve core is connected with the valve body through a hinge. The operating mechanism is used to operate the valve core to be rotated around the central axis of the hinge to open/close the valve. The motion-transferring device is used to transfer actions on the operating mechanism to the valve core, and when the valve is closed or open, the valve core is locked on the valve body through the locking device. The valve of the present invention has a compact structure, is easy to operate, requires a small torque for opening and allows a large flow when opened.
