Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing：
Fig. 1 is the structural schematic diagram of the reactor pressure vessel with supporting structure in the embodiment of the present invention；
Fig. 2 is the enlarged diagram of the supporting structure and the partial view A after pressure vessel assembling in Fig. 1.
Specific implementation mode
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
The specific implementation mode of the present invention.
As shown in Figure 1 and Figure 2, the reactor pressure vessel in a preferred embodiment of the invention includes upper shell 1, lower cylinder
Body 2 and supporting structure 3, supporting structure 3 include ring body 31,31 outer ring of ring body setting outer support 32, with
And the inner bearing portion 33 in the setting of 31 inner ring of ring body.
The end profile of ring body 31 is corresponding with the cross-section facial contour of the cylinder lateral wall of pressure vessel, when mounted, on
The lower face of cylinder 1 and the upper surface of lower shell 2 are connect with the two opposite sides of ring body 31 by the way of welding respectively, can
To allow ring body 31 as a part for pressure container cylinder, while the branch on the outside of outer support 32 and pressure vessel can be allowed
The connection of pedestal 4 is held, and inner bearing portion 33 is allowed to support the in-pile component 5 on the inside of pressure vessel.
Connecting interface of the ring body 31 as pressure vessel and outer support 32, inner bearing portion 33, makes supporting structure 3 need
The weight of entire pressure vessel dead weight and its interior all coolants and equipment is carried, ring body 31 is used as pressure container cylinder
A part, have enough strength and stiffness.
The bearing of hanging basket 51 in the bearing of reactor pressure vessel and heap and positioning are integrated on a ring body 31,
And as the component part of pressure container cylinder, directly with upper shell 1,2 butt welding of lower shell, ring body 31 both ensure that
Reliability and safety, and enhance economy.
In addition, the height and position of ring body 31 is suitable with the height of C.G. position of reactor pressure vessel so that transporting
The bearing point height Yu position of centre of gravity height of pressure vessel are close between the departure date, avoid under accident or earthquake operating mode due to two
The container that person's big height difference band comes acutely shakes, and increases reliability and the safety of reactor pressure vessel.
A part of the ring body 31 as reactor pressure vessel cylinder, directly with upper shell 1,2 butt welding of lower shell,
Solving may cause weld seam disconnected when bearing is arranged on pressure vessel sidewall face under conventional situation with the welding of cylinder plane-plane contact
It splits, the disadvantage that reliability is not high.
Outer support 32 is arranged in 31 outer ring of ring body along border, and inner bearing portion 33 is in 31 inner ring of ring body along border
Setting.32 upper edge border of outer support is equipped with the exterior lockhole 321 being connect with supporting base 4, and 33 upper edge border of inner bearing portion is equipped with
The interior lockhole 331 being connect with in-pile component 5.
Exterior lockhole 321 is worn by the outer support 32 in outside using locking parts such as bolts and supports the mixed of entire pressure vessel
4 surfaces of supporting bases such as solidifying mound hole are connected, thus by pressure vessel dead weight and its weight of internal coolant and other equipment
Amount is transmitted to 4 surface of supporting base.
In-pile component 5 includes hanging basket 51, and inner bearing portion 33 is supported on the downside of the flange 511 of hanging basket 51.Inner bearing portion 33
Upside be equipped with interior lockhole 331, flange 511 to be locked on inner bearing portion 33 by locking part.
Interior lockhole 331 is the blind hole set on the upside of inner bearing portion 33, passes through hanging basket 51 in locking part and pressure vessel
Flange 511 connects, for supporting all weight of in-pile component 5.
Inner bearing portion 33 is directly connected with 51 flange 511 of the hanging basket of in-pile component 5, supports in-pile component 5 and all heaps
The weight of core components, and cooperation is sealed between flange 511 and inner bearing portion 33, so that inner bearing portion 33 and flange 511 is hindered jointly
Enter the channel of upper gas space every ring cavity coolant.It solves since pressure vessel ring cavity liquid fluctuating causes cold conditions cold
But agent scurries into upper gas space without reactor core, causes the disadvantage that by-pass flow is big.
The inner bearing portion 33 of supporting structure 3 and the sealing of flange 511 of the hanging basket 51 of in-pile component 5 coordinate, and can ensure instead
In the case of answering core pressure vessel and in-pile component 5 that heap inner flow passage can be collectively formed, 51 height of hanging basket, solution are reduced to greatest extent
Having determined leads to axial direction and the big disadvantage of circumferential deformation since hanging basket 51 is long.
Ring body 31, outer support 32, inner bearing portion 33 are structure as a whole, allow reactor pressure vessel bearing and heap
The bearing of 5 hanging basket 51 of inner member integrates, and integrated forging may be implemented, reduce manufacturing cost.
Sealing ring 6 is equipped between flange 511 and inner bearing portion 33, sealing ring 6 is O-ring seal 6 or c-type sealing ring 6, is made
Sealing between flange 511 and inner bearing portion 33 is even closer.
5 hanging basket 51 of in-pile component obtains flange 511 and is connect with inner bearing portion 33 on ring body 31 in the present invention, and using close
6 structure of seal realizes sealing, solves since pressure vessel ring cavity liquid fluctuating causes cold conditions coolant to be altered without reactor core
Enter upper gas space, causes the disadvantage that by-pass flow is big.
It is to be appreciated that above-mentioned each technical characteristic can be used in any combination and unrestricted.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
