AI Technical Summary
During maintenance operations, there is a risk of flammable gas leaking into the atmospheric pressure environment in the hyperbaric system, which could lead to an explosion. Furthermore, the use of vacuum pumps in existing technologies may introduce oxygen to form an explosive mixture.
A venturi pump is used to apply sub-atmospheric pressure, and an oxygen-deficient gas is mixed with and removed from the system from the combustible gas. The concentration of the combustible gas is kept within a safe range, and fluid flow is controlled by a sealing block.
It reduces the risk of explosion, ensures the safety of maintenance operations, reduces oxygen entering the system, and improves the safety and controllability of operations.
