【Abstract】 The valve leakage inspection with acoustic emition technology was introduced, including the principle, probe construction and signal processing method. Trial and inspection on-site proved that inspecting the valve leakage with acoustic emition technology was possible, which was convenient, rapid and accurate. The application field of acoustic emition inspection was expanded and the leakage situation of valve was monitored effectively.更多还原
