Comparison of Traditional Window and Flange Type O-Ring Window
Comparison Diagram of Sealing Structures
Disadvantages of Traditional Window
● No Flange, no sealing grooves: The supporting surface is formed by bending and splicing of the chamber plates with poor flatness and weak support. And the O-ring is glued on the support surface.
● Sealing method: The hollow O-Ring is placed between the glass and supporting surface.
● Hollow O-Ring: By the compression deformation of the hollow O-Ring, the unevenness of the support surface gets Compensated. The hollow diameter is around 2 4mm, some poor-quality O-ring is up to 10mm. And there are wrinkles after the O-Ring is pressed which leads to a high leakage rate and unreliable sealing.
● A kind of Simple mechanical sealing,not a Vacuum sealing.
● Applicable for sealing of Large thin-walled parts whose sealing surface cannot be machined, or for simple sealing of non- vacuum equipment without quality requirements.
Features and Advantages of Flange type O-ring sealed Window
● The Flange for window sealing is integrallyprocessed, using one-cut milling by a largegantry machine, without seams on the sealinggroove and the sealing surface, which achievesthe flatness< 0.lmm/m.
● One-time laser welding of the Flangeintegrated with groove and the chamber body.with welding deformation<0.2mm.
● Easy for Window disassembly & reassemblyConvenient for operation and maintenance. Endusers are able to take care of Windowdisassembly themselves without needs fromprofessionals.
● The Flange type O-ring is embedded in thesealing groove, a way of vacuum air-tight seal.without breakpoints and seams, with strong corrosion resistance and good sealing performance, which improves the overall glovebox leakage rate to <0.0006vol%/h.
● Applicable for the sealing of vacuumequipment View Window and Sealing Door.
