DOMED DIAPHRAGM/INSERT PLATE FOR A PRESSURE VESSEL ACCESS CLOSURE |
摘要 |
A pressure vessel closure for an access opening that has a sealing surface surrounding the access opening and one of either a diaphragm or insert that spans the access opening with a peripheral flange that rests on the sealing surface. The insert or diaphragm has a continuously rounded portion that extends into the access opening and a cover extends over the insert or diaphragm. A gasket is interposed between the flange of the insert and the sealing surface or a fillet weld attaches the flange of the diaphragm to the sealing surface. A locking device secures the cover to a wall of the pressure vessel and urges the flange against the sealing surface. |
