AI Technical Summary
Existing tongue/groove flange gaskets are difficult to remove during disassembly and are prone to damaging the sealing surface, resulting in difficult disassembly and assembly and low efficiency.
A gasket removal groove is provided on the outside of the sealing groove of the flange. The cross-section is semi-circular and the depth is less than the depth of the sealing groove. Two gasket removal grooves are symmetrically arranged to facilitate the operation of removal tools and avoid damage to the sealing groove due to force on one side.
It enables convenient installation and removal of gaskets, improves work efficiency, protects the sealing surface of the flange from damage, and maintains sealing performance and structural strength.
