Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without having to pay creative labor, may be used also for those of ordinary skill in the art
With obtain other attached drawings according to these attached drawings.
Fig. 1 is a kind of structural representation of novel in-pile component sealing compressing structure one embodiment provided by the invention；
Fig. 2 is the enlarged diagram of part A in Fig. 1.
Specific implementation mode
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 describes, 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, those of ordinary skill in the art are obtained every other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, showing a kind of novel in-pile component sealing compressing structure one embodiment provided by the invention
Structural representation；The enlarged diagram in Fig. 1 is combined together.In the present embodiment, the novel reaction heap hanging basket exports the seal of tube
Structure, in presurized water reactor comprising：
The outlet 10 being set in cradle cylinder body 1, for passing through coolant；
The coolant outlet 20 being set on pressure vessel 2, the coolant outlet 20 and the coolant in the cradle cylinder body 1
Outlet 10 docks；
It is set to the sealing structure 3 of 10 position of the outlet, the sealing structure 3 includes：
It is welded on the jig 30 in 1 outside of cradle cylinder body, forms a plane outwardly, 30 one end of the jig（Figure
In be lower end）There is a gap 300 with 10 outer surface of outlet；
It is set in the bellows 30 in 10 outside of outlet, 31 one end of the bellows and the plane of the jig 30 are mutually solid
It is fixed；
Sliding sealing part, including one be slidably sleeved on the outside of the outlet 10 casing 32, it is remote in described sleeve pipe 32
Side from the jig 30 from radially outward from sealing plate 33,33 side of the sealing plate is remote with the bellows 31
The other end from the jig 30 is fixed.It is understood that 31 both ends of the bellows respectively with the jig
30, sealing plate 33 is used and is welded and fixed.
Wherein, there are accommodation spaces, described sleeve pipe 32 to be set between 10 outside of the bellows 31 and the outlet
And it can be free to slide in the accommodation space.
