Summary:The check valve actuated by a small pressure difference in the under water, is used for the cooling system of the atomic reactor or, if the pump fails, for forming flow passage by a temperature difference values of the fluid. The valve comprises a stationary chamber (5) with flow passages (5a)(5a') in the pipe (4), plug (3) inserted to the chamber (5) connected with an upper hollow balancer (1) by a connecting rod (2).
