Description

Technical Field

[0001] The utility model relates to the technical field of ship conduits, in particular to a multi-stage sealed ship conduit. Background Art

[0002] Ship is a general term for various vessels. Ship refers to a means of transportation that can sail or anchor in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements. Ship ducts are usually made of metal, plastic, glass and other materials, and are used to transport gases, liquids, solids and other substances.

[0003] If the sealing effect of the ship's duct is not good when connected, it will cause multiple serious problems, which may not only cause the leakage of gas, liquid or solid substances, causing environmental pollution, but also directly threaten the safety of crew members and cargoes. Especially for ships transporting flammable, explosive or toxic substances, the risk of leakage should not be underestimated. In addition, poor sealing will significantly reduce the operating efficiency and economy of the ship, waste precious resources such as fuel and water, and increase maintenance costs, including high maintenance costs, component replacement costs and operational losses caused by downtime maintenance. What's more serious is that leakage may also cause long-term damage to the ship's structure and equipment, accelerate the aging and failure of components, and even form explosive mixtures due to gas leakage, thereby increasing the risk of fire and explosion.

[0004] In order to solve the above problems, we have made improvements and proposed a multi-stage sealed ship duct. Utility Model Content
