Claim:
1. A valve with a hinged valve core, comprising: a valve body, a valve core, an operating mechanism, a motion-transferring device, and a locking device, the valve body is a housing, wherein the housing is formed with an operating hole used to partially accommodate the operating mechanism and a channel having an inlet and an outlet is formed in the housing, wherein: the valve core is connected with the valve body through a hinge constructed of hinge shafts provided on the valve core and hinge holes provided at the inlet of the channel of the valve body, and the valve core has a disc-shaped body and an outer periphery of the disc-shaped body is integrally provided with the hinge shafts; and the operating mechanism is used to operate the valve core to be rotated around a central axis of the hinge to open/close the valve and the central axis of the hinge is on the outer periphery of the disc-shaped body or outside of the outer periphery of the disc-shaped body, so that the valve core is opened outwardly from the valve body and located outside of the valve body after the valve is opened, wherein the operating mechanism comprises a handle and an operating member, wherein the operating member is rotatably held on the valve body and will not be able to move in the direction perpendicular to the direction of flow; and the motion-transferring device is used to transfer actions on the operating mechanism to the valve core, wherein the operating mechanism and the motion-transferring device form an eccentric cam mechanism together and the motion-transferring device is driven by the operating mechanism through the eccentric cam mechanism, and when the valve is closed or opened, the valve core is locked on the valve body through the locking device.
