Therefore, the detection of the tube body is of great importance, in particular in the production process of the tube body used. In actual production, it is not practical to send the pipe back to the manufacturer for detection in the regular detection work using the pipe, and even if the pipe is sent back to the manufacturer for detection, only a detection report of the manufacturer is obtained, and the detection process and the detection effect cannot be intuitively reflected.
There are several commonly used methods of gas tightness detection: immersion (bubble) detection, flow detection, direct pressure detection, differential pressure detection, helium detection, ultrasonic detection, and the like. A pipeline nondestructive testing device disclosed in CN213580839U is an ultrasonic testing method.
Among the above-mentioned detection methods, the immersion (bubble) detection method is a conventional air-tightness detection method. Is also a detection mode with lower cost. The medium is mainly water and soap solution. And sealing the tested workpiece, applying gas with certain pressure to the inner cavity of the tested workpiece, immersing the tested workpiece in a water tank, and observing whether bubbles are generated and the positions where the bubbles are generated so as to judge whether the workpiece leaks and the positions where the workpiece leaks. The detection method is simple to operate and low in cost. However, the method has lower efficiency, and the workpiece to be tested needs to be dried and subjected to rust prevention treatment after the detection is finished.
It is an object of the present application to provide a bubble detection device that is efficient, easy to carry for on-site detection, and does not require cleaning of the soap after detection.
