Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is that a kind of structure of novel in-pile component sealing compressing structure one embodiment provided by the utility model is shown
Meaning；
Fig. 2 is the enlarged diagram of part A in Fig. 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, showing a kind of novel in-pile component provided by the utility model seals compressing structure one implementation
The structural representation of example；The enlarged diagram in Fig. 1 is combined together.In the present embodiment, the novel reaction heap hanging basket outlet
Sealing 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 with it is cold in the cradle cylinder body 1
But agent outlet 10 docks；
It is set to the sealing structure 3 of 10 position of outlet, the sealing structure 3 includes:
It is welded on the welding platform 30 in 1 outside of cradle cylinder body, forms a plane outwardly, described 30 one end of welding platform
(being lower end in figure) has a gap 300 with 10 outer surface of outlet；
It is set in the bellows 30 in 10 outside of outlet, the plane phase of described 31 one end of bellows and the welding platform 30
It is fixed；
Sliding sealing part, the casing 32 for being slidably sleeved on 10 outside of outlet including one, in described sleeve pipe
The sealing plate 33 that 32 sides far from the welding platform 30 extend radially outward certainly, 33 side of sealing plate and the bellows
31 other ends far from the welding platform 30 are fixed.It is understood that 31 both ends of bellows respectively with the welding
Platform 30, sealing plate 33 are used and are welded and fixed.
Wherein, there are accommodation space between 10 outside of the bellows 31 and the outlet, described sleeve pipe 32 is set to
And it can be free to slide in the accommodation space.
