摘要： PROBLEM TO BE SOLVED: To provide an overflow preventing valve which allows valve opening/closing operation from the outside even if pressure difference inside a pipe cannot lead to valve closing action due to tiny leakage on a secondary side.
SOLUTION: The overflow preventing valve cuts off passage of fluid by abutment of a valve element onto a valve seat when the downstream side pressure inside a pipe drops. During normal circulation, a spherical valve element 60 is biased by a coil spring 70 in a direction separating from the valve seat 43, and retained by a supporting member 52. When carrying out the maintenance due to occurrence of tiny leakage on a secondary side, the valve closing operation is manually executed. By using magnetic force generated by a ring-shaped external magnetic circuit member 8 slidably provided in the outside of the valve and an internal magnetic circuit member 6 provided to the inside of the spherical valve element 60, the spherical valve element 60 is seated on the valve seat 43 against the biasing force of the coil spring 70 to perform the valve closing operation.
