Visualization Of Tests On Swing Type Check Valve Using Phased Array Sequence Scanning
US Patent:
2012018, Jul 19, 2012
Filed:
Mar 14, 2012
Appl. No.:
13/420066
Inventors:
Jesse R. Delgado - San Antonio TX, US
Hector Diaz - San Antonio TX, US
Hector Diaz - San Antonio TX, US
Assignee:
IHI SOUTHWEST TECHNOLOGIES, INC. - San Antonio TX
International Classification:
G01N 29/22
US Classification:
73592
Abstract:
Computers with proper programs generate signals in phased array sequence. In pulsers with delays, signals are fed through a multiplexor into multiple water wedges attached to a valve being tested. For a sequential operation of the valves from the open to the closed position, ultrasonic signals are transmitted through 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 valve to determine if the valve is operating properly. By using multiple water wedges and pass visualization software, the operator can see exactly how the valve is functioning, which information can be stored for inspections or maintenance.

US Classification:

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 a water wedge that is attached to a valve being tested. For a sequential operation of the 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 valve to determine if the valve is operating properly. By use of the water wedge, the top plate of the valve appears to disappear because the water wedge has the same refractive angle as the fluid contained in the valve.
