The needs that three generations's nuclear power ACP100 modular integral reactor designs due to structure, reactor pressure vessel and in-pile component axial flatulence of heat type difference are relatively big (reaching 5mm), the in-pile component holddown spring of existing structure form can not take into account the requirement of rigidity and compensation dosage simultaneously, it is necessary to designs the in-pile component holddown spring that a kind of reliability is high, compensation dosage is big.
Utility model content
This utility model technical issues that need to address are: existing holddown spring can not take into account the requirement of rigidity and compensation dosage simultaneously.
The technical solution of the utility model is as described below:
A kind of large compensation amount heterotypic spring, profile is to have the handstand conical shell of certain wall thickness, including: the vertex of a cone, transition cone section and the cone end, the vertex of a cone is connected to bore the end by transition cone section.
Preferably, the described vertex of a cone has anchor ring on the vertex of a cone, anchor ring under vertex of a cone lower inclined plane and the vertex of a cone;Under the described vertex of a cone, anchor ring transits to the outside cylinder of described large compensation amount heterotypic spring by vertex of a cone lower inclined plane, is used for preventing spring from interfering with peripheral structure produces when compression;On the described vertex of a cone, the internal diameter of anchor ring is more than the internal diameter of anchor ring under the described vertex of a cone.
Preferably, there is anchor ring under cone, cone end ramp and anchor ring at the cone end at the bottom of described cone;On at the bottom of described cone, anchor ring transits to the inner side cylinder of described large compensation amount heterotypic spring by cone end ramp, is used for preventing spring from interfering with peripheral structure produces when compression;The external diameter of anchor ring at the bottom of the external diameter of anchor ring is less than described cone under described cone.
Preferably, described transition cone section has upper arc surface and lower arc surface;The normal direction of described upper arc surface points to vertex of a cone direction, and the normal direction of described lower arc surface points to cone direction, the end, and upper arc surface is identical with the radius of lower arc surface;On at the bottom of described cone, anchor ring transits to anchor ring on the vertex of a cone by upper arc surface, and under described cone, anchor ring transits to anchor ring under the vertex of a cone by lower arc surface.
Preferably, under lower arc surface and the vertex of a cone, anchor ring engages on the circumference that place is formed, and three lifting eyes are further equally distributed, the lifting in time installing or removing.
The beneficial effects of the utility model are:
This novel spring rigidity is moderate, and reliability is high, and camber of spring compensates big, processing is simple, being particularly suitable for the compression of the internals of the big container of container internal-external temperature difference, such as ACP100 reactor core internals and the compression of the internals of other pressures vessels for the chemical industry, application market is wide.
