[0002] The air-tightness test is mainly to check whether there is leakage in the connection parts of the container. The pressure vessels with extremely toxic or highly hazardous media or the pressure vessels that are not allowed to have even a little leakage in the design must be subjected to air-tightness test.

[0003] At present, a Chinese patent with announcement number CN110410524B discloses a three-way valve that is easy to detect air tightness; it includes a valve body; the valve body has an air inlet and two air outlets that are interconnected; it also includes a leakage detection unit; air outlets are respectively provided with air outlet pipes; and detection holes are respectively opened at the connection between the valve body and the air outlet pipes; the present invention can detect the air tightness of the three-way valve in real time according to the use of the sealing ring. When the sealing ring is damaged, the detection hole is connected with the air outlet, and the leakage detection unit performs precise detection of the three-way valve according to the effect of the leaked gas. At the same time, the air tightness of the three-way valve can be detected without disassembling the three-way valve. The structure is simple, the detection work of the air tightness of the three-way valve is simplified, and the work efficiency is increased.
