Description

Technical Field

[0001] This invention relates to the field of vacuum flap valve technology, and in particular to a bidirectional sealing vacuum water-cooled flap valve. Background Technology

[0002] Currently, continuous vacuum coating production lines consist of multiple functional vacuum chamber valve bodies connected in series. Since each functional vacuum chamber valve body has different requirements for vacuum level and different internal process gas compositions, vacuum flap valves are needed to isolate the functional vacuum chamber valve bodies.

[0003] In existing technology, vacuum chamber valves use flap valves to achieve unidirectional sealing. If the middle vacuum chamber valve is emptied alone, the unidirectional sealing flap valve is insufficient to seal the other side vacuum chamber valves. The atmospheric pressure in the opposite direction will push the valve plate open directly, inevitably breaking the vacuum in the vacuum chamber valves on both sides. In actual production, most maintenance involves maintaining the internal components of the middle vacuum chamber valve or addressing alarms caused by problems with the middle vacuum chamber valve. Only the middle vacuum chamber valve needs to be emptied for operation, without needing to empty the other vacuum chamber valves at both ends. Therefore, designing a bidirectional sealing flap valve is essential.

[0004] In response to the aforementioned technologies, there is an urgent need to design a bidirectional sealed vacuum water-cooled flap valve, so that when the valve body of the intermediate vacuum chamber is undergoing normal maintenance or repair, the valve bodies of other vacuum chambers can maintain a vacuum state, and subsequent production products will not be affected, thus achieving the effect of segmented vacuuming of large-scale continuous coating production lines.
