The valve diameter is generally large, and the switch operation is inconvenient. At the same time, the static pressure generated by the material liquid surface may cause the material to flow back to the pipeline. In addition, in production, the pressure in the main pipeline will increase due to the transfer of materials or the increase in external temperature. If the pressure increases for a long time and cannot be released, the flange will leak. Summary of the invention
