Abstract:The black-water regulating valve is very easy to be damaged due to the erosion of the key components, such as valve spool and valve seat. This work presents the failure analysis of the spool and seat of regulating valve in the black-water treatment system. Scanning electron microscopy (SEM) and X-ray energy dispersive spectrometer (EDS) were used to detect the morphology and chemical compositions of failure valve samples. The computational fluid dynamics (CFD) method was also adopted to simulate the medium flo… Show more
