Abstract
To provide a motor-operated valve diagnosing device capable of making a highly accurate diagnosis at a low cost. In a motor-operated valve diagnosing device for diagnosing a motor-operated valve having a motor-operated valve having a valve element driving part for opening and closing a valve element, and a spring cartridge which expands and contracts in proportion to a reaction force exerted thereon from the valve element driving part, a spring compression mechanism or a worm displacement measuring means is configured to be attached to the valve element driving part via an adapter. With this configuration, the spring compression mechanism and so on can be easily attached to and removed from the valve element driving part. In addition, since the spring compression mechanism and so on can be attached to the valve element driving part without any alternation of the valve element driving part, the spring compression mechanism can be shared by two or more motor-operated valves, and reduction of expense for a diagnosis of a motor-operated valve and improvement in accuracy of diagnosis can be achieved.
