专利汇可以提供Pressure-proof connection for nuclear reactor pressure vessels专利检索，专利查询，专利分析的服务。并且A pressure-proof connection is provided between a nuclear reactor pressure vessel cover member and a ring shaped member about the cover member. The connection comprises at least two rows of levers disposed one above the other positioned between the cover member and ring. The levers are moved by a cylindrical plate to either lock or unlock the cover and ring member.，下面是Pressure-proof connection for nuclear reactor pressure vessels专利的具体信息内容。

权利要求

1. Pressure-proof connection between a nuclear reactor pressure vessel cover member and a base member formed of steel, concrete or other pressure-proof materials and having a substantially cylindrical wall, comprising at least two rows of pressure-loaded levers disposed one above the other between said cylindrical wall and said cover member, said cylindrical wall having a plurality of niches into which said pressure-loaded levers are displaceable to form the pressure-proof connection, a cylindrical lifting plate disposed between said cylindrical wall and said cover, said lifting plate having openings for said pressure-loaded levers, said lifting plate being displaceable to engage said pressureloaded levers and retract the latter from their engaged position in said niches in said cylindrical wall.

2. Pressure-proof connection according to claim 1, including releasable fixing means comprising a respective hinge pin securing said pressure-loaded levers to said cover member.

3. Pressure-proof connection according to claim 1, including releasable fixing means comprising a respective joint securing said pressure-loaded levers to said cover member.

4. Pressure-proof connection according to claim 1, including spring means for augmenting gravity force by which said pressure-loaded levers fall into said respective niches formed in said substantially cylindrical wall and for biasing said levers into correct starting position for performing a rolling motion.
