Description

Technical Field

[0001] This utility model relates to the field of internal floating disc technology, and in particular to an internal floating disc elastic sealing mechanism. Background Technology

[0002] When storing materials in storage tanks, the tanks may not be completely filled, and evaporation can occur, leading to potential hazards and resource waste. Therefore, internal floating roofs are needed to ensure safety and reduce evaporation. However, currently used internal floating roofs often suffer from poor sealing after long-term use. For example, China has published an application for "An Internal Floating Rope" (application number: CN201721612138.2). While this design uses a sealing ball to seal the drain hole when there is no oil or very little oil, it cannot guarantee the internal floating roof will maintain its elasticity and sealing effect over long-term use. This means it cannot effectively prevent liquid and gas leaks, ensuring equipment safety. Furthermore, it cannot quickly remove safety equipment during maintenance, failing to improve convenience and safety. Utility Model Content
