Title: SEALING DEVICE AND GROUPING UNIT OF NATURAL GAS STORAGE SYSTEM OF CNG TRANSPORT SHIP
Abstract:
A sealing device of a natural gas storage system of a CNG transport ship, comprising a sealing box (2) for a pollution discharge pipeline and a sealing box (10) for a gas loading and discharging pipeline. The sealing box (2) for a pollution discharge pipeline and the sealing box (10) for a gas loading and discharging pipeline are provided on bottom portions and/or top portions of gas bottles or bottle type containers of a grouping unit for gas bottles (1) or bottle type containers in the natural gas storage system, and are filled with a protective gas. A pollution discharge pipeline (A) is located in the sealing box (2) for a pollution discharge pipeline, and a control valve matching the pollution discharge pipeline is located outside the gas bottles (1). A gas loading and discharging pipeline (B) is located in the sealing box (10) for a gas loading and discharging pipeline, and a control valve matching the gas loading and discharging pipeline is located outside the gas bottles (1). The sealing device has no root valves of gas bottles, reducing leakage points, ensuring the safety of the whole natural gas storage system.
