Fig. 3 is a kind of longitudinal sectional view of novel in-pile component sealing another embodiment of compressing structure provided by the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, being a kind of longitudinal direction of novel in-pile component sealing compressing structure one embodiment provided by the invention
Cross-sectional view；Together as shown in connection with fig. 2.In the present embodiment, the novel in-pile component seals compressing structure, double for compact
In the presurized water reactor of layer casing comprising:
The outlet nozzle bearing cylinder being installed in the pressure vessel (not shown) respective step of presurized water reactor, the outlet nozzle bearing
Cylinder lower part is provided with the first supported flange 10 extended radially inward；
Tubular hanging basket 2 is sheathed in the outlet nozzle bearing cylinder 1, and the hanging basket 2 is provided with the second pressure extended radially outwards
