Within enclosing.
According to FIG. 1 to FIG. 2, one kind provided by the utility model is bolted sealing structure, the connection for container 1
Sealing, the chamber wall of the container 1 include at least two layers, respectively internal layer container wall 2 and outer layer container wall 3, and the bolt connects
Connecing sealing structure includes, bolt 4, and the nut 5 of described 4 one end of bolt is located at the inside of the container 1,4 other end of bolt
Nut 6 be located at the outside of the container 1, be arranged on the bolt 4 between the nut 5 and the internal layer container wall 2
One gasket 7 is arranged with the second gasket 8, the nut on the bolt 4 between the internal layer container wall 2 and outer layer container wall 3
Third gasket 9 is arranged on bolt 4 between 6 and the outer layer container wall 3, the third gasket 9 includes at least two
The butterfly elastic washer 10 of make-up.
Further, the third gasket 9 is the butterfly elastic washer 10 of two make-ups used in the present embodiment,
In other embodiments, adapt between the nut 6 and outer vessel walls 3 apart from when, the butterfly of multiple groups make-up can also be set
Shape elastic washer 10 forms the third gasket 9, guarantees the sealed connection of bolt root and the container 1, the butterfly bullet
Property washer 10 use spring steel material, its elastic energy accumulation can be kept for a long time after tightening bolt, remain bolt root and the
Three gaskets 9 are in close contact, and sealing effect is more preferable.
Further, the outer rim of first gasket 7 extends to form extension 11, the extension towards the nut 5
Portion 11 is located on 5 outer wall of nut, be tightly connected the bolt 4 nut 5 and the inner container wall 2.
Further, second gasket 8 is combination sealing pad comprising first annular the 12, second annular of rubber layer
Rubber layer 13 and third annular rubber layer 14, second annular rubber layer 13 are located at the first annular rubber layer 12 and third
Between annular rubber layer 14, annular asbestos layer of cloth 15, the first annular rubber are provided in second annular rubber layer 13
Glue-line 12, the second annular rubber layer 13 and the compacting of third annular rubber layer 14 are structure as a whole, the first annular rubber layer 12,
Second annular rubber layer 13 and third annular rubber layer 14 are made of oil resistant temperature resistant rubber, load asbestos layer of cloth wherein, make
Obtaining the second gasket 8 has suitable hardness and flexibility, when bolt root is tightened, even if there is bolt rotation phenomenon, also not
Gasket can be damaged, appropriate bolt end sealing effect can be formed after tightening.
Further, it is the flexible meet demand for guaranteeing seal washer, be the setting annular asbestos layer of cloth 15 is bilayer
