Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air tightness testing, in particular to an air tightness testing device for a bent pipe. Background Art
[0002] After the bending tube is processed, it is necessary to perform an air tightness test on the bending tube to detect the unqualified bending tube. The existing method for testing the air tightness of the bending tube requires first closing one end of the bending tube, then clamping the bending tube through a clamping mechanism, and then connecting the bending tube to the test equipment for testing. This test method has low clamping and sealing efficiency. At the same time, when performing the air tightness test, the air pressure in the bending tube is relatively high, which will generate a thrust on the clamping mechanism, causing the bending tube to move, and the detection device to leak and fail, and needs to be adjusted frequently, which leads to low test efficiency.
