[0003] Based on the above, the inventor found that: at present, there are many devices for sealed connection between a tank body and a valve body on the market. However, for a general device for sealed connection between a tank body and a valve body, the valve body and the tank body are matched and installed by workers, so that the outer surfaces of the valve body and the tank body are impacted by external forces, which is very likely to cause loosening at the joint between the valve body and the tank body, thus affecting the sealed connection between the valve body and the tank body, and thus very likely to cause leakage of the items transported inside the valve body and the tank body. Therefore, in view of this, the existing structure is studied and improved to provide a device for sealed connection between a tank body and a valve body, in order to achieve a more practical value purpose.
