[0002] An atmospheric pressure storage tank is a container that stores liquid, gaseous or solid substances at normal pressure. In contrast, a pressure vessel is a container with a certain pressure-bearing capacity and is often used to store gas or liquid under high pressure. The main difference is that an atmospheric pressure storage tank does not require pressurization during operation, while a pressure vessel needs to maintain a certain internal pressure. Therefore, an atmospheric pressure storage tank is usually considered a non-pressure vessel. This device is a rapid sealing measurement device for atmospheric pressure storage tanks, which is used to detect the sealing condition of atmospheric pressure storage tanks.
