Description

Glass flange connection structure of observation window Technical Field The utility model relates to the technical field of mechanical sealing, in particular to a flange connection structure of observation window glass. Background The vacuum observation window, also called vacuum window, is an optical Feedthrough, is commonly used for monitoring the production condition inside the vacuum container or transmitting light source, and the glass material used for monitoring the production condition inside the vacuum can be quartz glass or optical glass. The existing flange connection structure of the observation window mostly adopts a single sealing mode, for example, only relies on rubber gaskets or plane pressing sealing. Such structures are prone to seal failure due to material aging, thermal expansion and contraction or pressure fluctuation during long-term use, resulting in leakage of media or invasion of external pollutants. In addition, if the traditional structure is not accurately aligned during installation, local sealing gaps are easy to form, and reliability is further reduced, so that the vacuum observation window flange with the structure for connecting the observation window glass flange is provided for solving the problems of poor sealing performance and convenience in installation. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides an observation window glass flange connection structure, which has the advantages of enhancing the friction force and deformation compensation capability of a sealing surface and the like through the design of wavy or zigzag continuous lines, and solves the problems of poor sealing caused by the fact that the friction force of a sealing structure is insufficient and the sealing structure is easy to form due to expansion caused by heat and contraction caused by cold. In order to achieve the above purpose, the technical scheme is that the observation window glass flange connection structure comprises a flange ring, a packaging metal ring and a visual glass sheet, wherein a glass sheet caulking groove is formed in the flange ring, the visual glass sheet is embedded into the glass sheet caulking groove, a ring of metal ring buckling groove communicated with the glass sheet caulking groove is further formed in the top of the flange ring, the packaging metal ring is buckled and pressed above the metal ring buckling groove, a ring of glass sheet outer protruding ring is arranged on the outer surface of the visual glass sheet, an anti-slip sealing groove is formed in the bottom of the glass sheet caulking groove, a metal ring sealing groove is formed in the bottom of the packaging metal ring, and two rubber pads are arranged between the glass sheet outer protruding ring and the anti-slip sealing groove interlayer and between the metal ring sealing groove and the glass sheet outer protruding ring. Further, the visible glass sheet and the outer convex ring of the glass sheet are intersected to form a trapezoid layer, and the trapezoid layer is respectively in clearance fit with the inner ring of the packaging metal ring and the inner ring of the bottom of the flange ring. Further, the anti-skid seal groove and the metal ring seal groove are wavy or zigzag continuous lines, so that enough friction is generated when the surfaces of the rubber pads pressed on the anti-skid seal groove and the metal ring seal groove are contacted with the wavy or zigzag continuous lines of the anti-skid seal groove and the metal ring seal groove, and the engagement depth of the anti-skid seal groove and the metal ring seal groove is 0.5-1.2mm. Furthermore, a plurality of connection limiting holes are further formed in the surface of the flange ring, and the connection limiting holes are used for connecting the observation window glass flange with the fixing holes of the device. Compared with the prior art, the technical scheme of the application has the following beneficial effects: This observation window glass flange connection structure prevents installation skew through the trapezoidal design of glass piece evagination circle, and groove interlock structure compensation expend with heat and contract with cold deformation to and wave or zigzag groove increase area of contact and frictional force that antiskid seal groove and metal ring seal groove formed avoid sealed face slip inefficacy.
