Abstract
The invention belongs to the technical field of ultrasonic non-destructive detection and relates to a jet flow immersion ultrasonic detecting method and a liquid sprayer. According to the detection method, a symmetrical radial flow injection mode is adopted for controlling coupling agents in a flowing mode, so that uniformity of injected flow and initial speed are ensured. A double-layer multi-hole screen structure is arranged on a coupling agent flowing channel, so that double-layer rectification is achieved to obtain a stable laminar condition. The liquid sprayer is composed of a nozzle, a first bolt assembly, a first sealing ring, a liquid sprayer base body, a first liquid injection nozzle, a probe clamping sleeve, a second sealing ring and a second liquid injection nozzle. Due to the reverse arc inner surface of the nozzle, the possibility that due to the fact that high-pressure flowing liquid impacts the inner wall, turbulence is formed on the inner wall is reduced, and the turbulence intensity level on an ultrasonic transmitting channel is lowered; the number of assemblies in the liquid sprayer is small, and therefore the structure is compact and simple; the method is used for carry out ultrasonic detection on focus type ultrasonic probe jet flow immersion, parts can be detected automatically on machines, operation is easy to carry out, the structure is reliable, and the efficiency is high.
