Abstract

PURPOSE: To prevent damage by frequent by frequent operation by providing by- pass flow passage with a by-pass valve on a valve in the automatic pressure reducing system, and also to maintain the function as a safety valve in cose of the loss of working gas.
CONSTITUTION: The safety valve functions normally as the by-pass valve is closed at the normal operation. That is, the safety valve is opened by shifting the valve 4 upward resisting the force of the spring 3 by the pressure rise of the nuclear reactor. When the safety valve has to be opened in case such as stopping operation for safety, the function is effected by opening the by-pass valve 17, and the valve 4 needs not be opened. When the piston 10 can not be operated by the leak, etc. and the valve 4 cannot be operated, the by-pass valve 17 is electrically opened so that it can function as a valve in the automatic pressure reducing system.
