[0002] The current method requires observing whether air bubbles appear in the grooved pipe fittings in water to test the airtightness. This method has low testing efficiency, is cumbersome to operate, and has poor adaptability, failing to meet people's requirements.

[0003] To address the aforementioned problems, existing technology CN217006216U provides a novel grooved pipe fitting airtightness testing device, comprising a base plate, with a first vertical plate and a second vertical plate fixedly connected to the top two ends of the base plate respectively. A grooved pipe fitting is disposed on the top of the base plate and between the first and second vertical plates. A connecting rod is fixedly connected to the side of the first vertical plate near the grooved pipe fitting, and a telescopic rod is fixedly connected to the side of the second vertical plate near the grooved pipe fitting. Sealing components for sealing and fixing the grooved pipe fitting are fixedly connected to the opposite end faces of the connecting rod and the telescopic rod, wherein one of the sealing components is fixedly connected to a... The second conduit connected to the sealed cavity has an upper shell and a lower shell symmetrically arranged on the outer side of the grooved pipe fitting. The two ends of the upper shell and the lower shell are fixedly connected to the grooved pipe fitting by clamps. The two ends of the clamps are connected by bolts. The upper shell and the lower shell can cooperate to form a sealed cavity to accommodate the grooved pipe fitting. The outer side of the lower shell has a first conduit connected to the sealed cavity. One end of the first conduit is connected to a detection airbag. The outer side of the detection airbag has a first air valve. This utility model detects the airtightness of the grooved pipe fitting by observing whether the detection airbag changes, which replaces the existing underwater detection environment, improves the accuracy of detection, and has better applicability.
