A water-cooling valve stem structure of a 1500-DEG C superhigh temperature valve comprises a valve stem. The valve stem is of reduction structure and provided with a single-circulating water cooling structure. The valve stem is formed by fixedly connecting a valve stem body and a valve stem joint, and the external portion of the valve stem body is of reduction structure composed of a large-diameter section and a small-diameter section which are connected through a transition section. Cooling water can flow in the space formed by the valve stem body, a valve stem bush, an inner water-cooling pipe and the valve stem joint to form a single complete cycle of a water cooling system. An O-shaped ring in the inner water-cooling pipe prevents water from entering an outlet from the bottom of the inner water-cooling pipe and prevents water at the outlet from reaching the inlet from a sealed position of the O-shaped ring, so that water cooling in a single complete cycle is formed. The valve stem can safely and reliably operate under the working condition of superhigh temperature of 1500 DEG C through thermodynamic calculation of heat transfer.
