Description

Technical Field

[0002] The existing overflow pipes can be divided into common overflow and individual overflow. Different measures are used to meet the stability requirements.

[0003] Meeting stability requirements for a common overflow pipe presented the following challenges: The pipe diameter was too large, requiring the common overflow pipe to reach the damaged waterline, resulting in wasted pipe material. Meeting stability requirements for a separate overflow pipe presented the following challenges: Without any valves, the cabin could be flooded. Adding a check valve to the bulkhead outlet prevented the check valve from opening during overflow, causing water to leak from the vent pipe. Summary of the Invention
