Abstract: An ultra-high temperature (UHT) rigidity seal ball valve that includes an upper cover, a valve cover, a valve body, a valve rod and a ball body. The valve seat is arranged in the valve body; the valve rod penetrates the upper cover and the valve cover sequentially and connects to the ball body; a sealing element is arranged between the upper cover and the valve rod and between the valve cover and the valve rod; the ball body includes a medium channel; a hermetically-sealed cooling cavity encircles the outside of the medium channel of the ball body; a through hole allowing cooling liquid to pass through to the cooling cavity is formed in the valve rod. An accommodating cavity is arranged in the ball body; the through communicates with the accommodating cavity, so that cooling liquid can be introduced to a product when the valve operates at an ultra-high temperature.
