DEVICE FOR EXAMINING PERFORMANCE OF MOTOR DRIVE VALVE

摘要

PURPOSE: A device for examining the performance of a motor drive valve is provided to perform an examination even at a position where a stem sensor is difficult to attach by employing a stem adapter. CONSTITUTION: A device for examining the performance of a motor drive valve comprises a pair of bodies(100) formed in the semi-cylindrical shape and fastening units(102) integrally combined to the upper and lower faces of the bodies. A connecting unit(104) having a thread is formed in the fastening unit to be connected with a bolt(110) and a nut(112). While the bodies are combined by the bolt and the nut, a stem sensor(10) is attached to the body. Thus, the stress applied to a stem is measured.
