Structural Module Partition and Fault Diagnosis of Nuclear Electric Valve Based on Function Analysis

Abstract:

The electric valve cutting off or connecting pipeline of nuclear equipment is an essential component of nuclear facilities for safe operation, whose reliability directly determines working performance of entire nuclear device. Based on function analysis, module partition and structure analysis of valve have been carried out in the paper, and the direct correspondence between common faults and structural modularization of valve has been established. Furthermore, the proper methods and procedures of fault diagnosis for nuclear valve are put forward, which can guarantee safe operation of nuclear facilities.
