| description | The invention discloses a high-temperature gas cooled reactor primary circuit nuclear-grade ball valve, and belongs to the field of ball valve design, the high-temperature gas cooled reactor primary circuit nuclear-grade ball valve comprises a valve shell and a valve cover, and a cavity for placing a valve core assembly is arranged between the valve cover and the valve shell; the valve element assembly comprises a valve cage and a ball body, and a pressing sleeve is further arranged between the valve cage and the ball body. And elastic pieces are respectively arranged between the pressing sleeve and the valve cage and between the pressing sleeve and the ball body. According to the ball valve, the elastic piece is arranged in the valve element assembly, so that when the ball valve is opened and closed, abrasion of an inner sealing piece can be avoided, the service life is prolonged, and meanwhile the inner leakage rate can be reduced.
