Abstract: A valve maintenance assistance device includes: a valve ID storing portion configured to store IDs of an ON-OFF valve which may be a candidate for maintenance; an opening acquiring portion configured to acquire opening measurement data from an opening sensor provided on the ON-OFF valve; a pressure acquiring portion configured to acquire pressure measurement data on operating device air supplied to an operating device of the ON-OFF valve; a storing portion configured to store the opening measurement data and the pressure measurement data; and a diagnosis index calculating portion configured to calculate a dead zone time from when an operating device air pressure is changed until an opening degree of the ON-OFF valve is changed as a diagnosis index based on the pressure measurement data and the opening measurement data; and a diagnosis index presenting portion configured to present a numerical value of the diagnosis index calculated by the diagnosis index calculating portion.

Abstract: A valve abnormality detecting device includes an opening acquiring portion to acquire a valve opening value; a pressure acquiring portion to acquire a pressure value of operating device air of an operating device for a valve; a stability-time detecting portion configured to detect a stable-opening state in which the valve opening value acquired by the opening acquiring portion 1 is substantially constant; a frictional force detecting portion configured to detect a difference between a maximum pressure value and a minimum pressure value of the operating device air in the stable-opening state as an index value indicating a frictional force at a sliding portion of the valve; and an abnormality determining portion configured to determine that an abnormality may have occurred in the valve in a case where a frequency of occurrence of reduction in which the index value falls below a specified value is an abnormal frequency.

Abstract: A stick slip detection system includes: an operation data storage unit configured to store a stick slip index, the stick slip index being a ratio of a first state amount based on a displacement of a valve shaft of a valve to be diagnosed to a second state amount based on the displacement; an abnormality diagnosis unit configured to determine whether a stick slip phenomenon occurs in the diagnosis target based on the stick slip index; and a diagnosis operation control unit configured to, when a stepwise change in a control command value in an intermediate opening degree of the valve to be diagnosed is detected, stop a determination operation of the abnormality diagnosis unit. The present disclosure makes it possible to easily reflect knowledge of an expert with respect to a diagnosis target such as a valve in the stick slip detection system and method.
