Abstract
A computer with a proper program generates a phased array sequence of signals. In a pulser with delays, the signals are fed through a multiplexor into multiple water wedges that are attached to a globe valve being tested. For a sequential operation of the globe valves from the open to the closed position, ultrasonic signals are transmitted through the fluid contained in the valve and reflected back through piezo-electric crystals to the multiplexor. By summation and merger of the signals, an image can be developed of the operation of the globe valve to determine if the globe valve is operating properly. By comparing the signals received with a known standard for that globe valve, proper operation, or lack thereof, of the globe valve under test can be determined. Separation of the valve stem from the globe can also be measured.
