Background technique

A pressure vessel is a closed container that can withstand pressure. It has a wide range of uses. It plays an important role in many sectors such as industry, civil use, and military industry, as well as in many fields of scientific research. Nowadays, common pressure vessels include storage tanks, oil and gas tanks, air compressor tanks, etc.

During the production and manufacturing process of pressure vessels, in order to ensure that each container has good air tightness, it needs to undergo a pressure test before leaving the factory. In traditional technology, the way to test the sealing of a pressure vessel is to blow high-pressure gas into the container, then place the container in water and observe whether there are bubbles emerging. If there are bubbles, it means the container is not airtight; On the contrary, it means that the container is airtight. Although the above method can theoretically detect the air tightness of the pressure vessel, it must be carefully observed by the staff; for some containers, the cracks are very slight and the leakage rate is very slow, so the bubbles generated when placed in water are also They are very small. If the staff does not pay attention, they may miss the best opportunity to observe the bubbles, and thus cannot accurately determine whether the pressure vessel is leaking. In order to more intuitively determine whether the pressure vessel is leaking, we propose a pressure vessel leakage detection device to effectively solve the above disadvantages.
