AI Technical Summary
The airbags of underwater vehicles are easily ruptured under seawater pressure, causing buoyancy regulation to fail. Furthermore, the bidirectional air supply channels are prone to seawater backflow, which can damage the electrical system.
A one-way shut-off airbag adjustment device was designed, comprising an airbag end cap, a ferrule, a valve core, an O-ring seal, and a support spring. It automatically closes the air supply channel using seawater pressure to prevent seawater backflow, and achieves stable installation of the device through a threaded connection.
It achieves automatic closure of the air supply channel when the airbag ruptures, preventing seawater backflow, ensuring the safety and reliability of the underwater vehicle, and preventing the airbag rubber from being cut by metal. The structure is simple and the operation is automated.
