[0002] With the continuous development and improvement of the industrial production process, the problem of liquid material leakage during transportation has become increasingly prominent. Especially during the tank feeding process, due to gaps and defects in equipment such as pipelines and valves, material leakage not only affects product quality and production efficiency but may also lead to environmental pollution and safety accidents. Therefore, it is necessary to seal the feeding port of the tank.

[0003] The existing original sealing structure of the feeding port uses a thick steel plate as a cover plate for sealing, and then multiple stainless steel bolts are used for fixation, and a sealing gasket is installed inside the cover plate. When opening and closing the feeding port, it is necessary to disassemble and assemble the stainless steel bolts and the sealing gasket one by one and carry the thick steel plate. This solution has complex disassembly and assembly operations, the position of the sealing gasket is often incorrect, and the bolts are not evenly tightened, resulting in poor sealing of the feeding port during the operation of the equipment, leakage of acetone gas, and great potential safety hazards. Moreover, some tanks generate relatively large pressures during operation, and the sealing device may be loosened due to excessive pressure, which will affect the sealing effect of the device.
