Description
Technical field
The present invention relates to close-coupled reactor structure field, imported and exported more particularly to a kind of steam generator water chamber head
Ozzle integral structure.
Background technology
Small modular reactor uses close-coupled arrangement.Close-coupled arrangement is cancelled on the basis of dispersed placement
Pipeline between equipment, and equipment is directly connected by importing and exporting ozzle, reactor plant characteristics of compact layout is so as to save
Arrangement space needed for system.Due to eliminating the connection ozzle of the large scale between equipment, generation large break dehydration thing is reduced
Therefore possibility, therefore nuclear reactor safety is improved.Due to being eliminated between reactor pressure vessel and steam generator
Main pipeline, they are direct-connected by ozzle, it is necessary to a kind of special construction is designed, to realize that this structure need to be to the hydroecium of steam generator
End socket internal chamber is designed.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes that a kind of steam generator water chamber head imports and exports ozzle integration knot
Structure.
Steam generator water chamber head imports and exports ozzle integral structure includes end socket solid forging, hydroecium dividing plate and turnover
Mouth ozzle dividing plate；Wherein, water chamber head is separated into hot side and cold side two chambers by the end socket dividing plate；The import and export ozzle
Dividing plate is separated into top hot side and bottom cold side two parts by ozzle is imported and exported.
Preferably, the reactor coolant from reactor pressure vessel is entered by the upper flow passage of the import and export ozzle
Enter steam generator water chamber head inlet chamber, then flow upwardly into heat-transfer pipe.
Preferably, after the reactor coolant of the inflow heat-transfer pipe rejects heat to secondary side fluid through heat-transfer pipe,
Water chamber head outlet chamber is flowed downwardly into, and flows into pump case chamber.
Preferably, by importing and exporting ozzle dividing plate after the reactor coolant of the inflow pump case chamber pressurizes after through pump
Lower flow passage flows back to reactor pressure vessel, completes a circulation.
Compared with prior art, the invention has the advantages that：
1st, the steam generator water chamber head that the present invention is provided imports and exports ozzle integral structure, steam generator and reaction
Core pressure vessel is directly connected to using single tube mouth, eliminates main pipeline, and reactor coolant is divided into top hot side by ozzle dividing plate
With bottom cold side.
2nd, the steam generator water chamber head that the present invention is provided imports and exports ozzle integral structure, it is adaptable to small modular
Close-coupled reactor arrangement.The setting for importing and exporting ozzle dividing plate enters the heat of steam generator there is provided reactor coolant
Side runner and the cold side runner for leaving steam generator.
Brief description of the drawings
Fig. 1 imports and exports ozzle integral structure schematic diagram for the steam generator water chamber head that the present invention is provided.
Specific embodiment
It is below in conjunction with the accompanying drawings and specific real to enable the above objects, features and advantages of the present invention more obvious understandable
The present invention is further detailed explanation to apply mode.
As shown in figure 1, steam generator water chamber head imports and exports ozzle integral structure includes end socket solid forging, hydroecium
Dividing plate and import and export ozzle dividing plate；Wherein, water chamber head is separated into hot side and cold side two chambers by the end socket dividing plate；It is described
Import and export ozzle dividing plate and be separated into top hot side and bottom cold side two parts by ozzle is imported and exported.From reactor pressure vessel
Reactor coolant enters steam generator water chamber head inlet chamber by the upper flow passage of the import and export ozzle, then upwards
Flow into heat-transfer pipe.Flow into the heat-transfer pipe reactor coolant reject heat to secondary side fluid through heat-transfer pipe after, downwards
Water chamber head outlet chamber is flowed into, and flows into pump case chamber.The reactor coolant for flowing into the pump case chamber adds after through pump
Reactor pressure vessel is flowed back to by importing and exporting ozzle the lower partition runner after pressure, (arrow in Fig. 1 is represented to complete a circulation
Reactor coolant is flowed to).
The manufacture that the water chamber head of the present embodiment imports and exports ozzle integral structure can be combined by " forging+machining "
Technique realize.Concrete mode is first solid forging shaping, for the part that forging cannot be directly realized by, by being machined to
Type.The main manufacturing process of water chamber head solid forging is：Smelting ingot casting → forging → heat treatment after forging → roughing → ultrasound
Ripple detection → property heat treatment → machining sampling → inspection (chemical composition, mechanical performance, metal lographic examination etc.) → machining →
Non-Destructive Testing.Then it is machined out shaping.It is last that hydroecium dividing plate is passed through into welding and water respectively with ozzle dividing plate is imported and exported again
Room end socket solid forging connection.
Compared with prior art, the present embodiment has the advantages that：
1st, the present embodiment provide steam generator water chamber head import and export ozzle integral structure, steam generator with it is anti-
Answer core pressure vessel to be directly connected to using single tube mouth, eliminate main pipeline, reactor coolant is divided into top heat by ozzle dividing plate
Side and bottom cold side.
2nd, the steam generator water chamber head that the present embodiment is provided imports and exports ozzle integral structure, it is adaptable to small modules
Change close-coupled reactor arrangement.The setting for importing and exporting ozzle dividing plate enters steam generator there is provided reactor coolant
Hot side runner and the cold side runner for leaving steam generator.
Each embodiment is described by the way of progressive in this specification, and what each embodiment was stressed is and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.For system disclosed in embodiment
For, due to corresponding to the method disclosed in Example, so description is fairly simple, related part is referring to method part illustration
.
Those skilled in the art can realize described function to each specific application using distinct methods, but
It is this realization it is not considered that beyond the scope of this invention.
Obviously, those skilled in the art can carry out various changes and modification without deviating from spirit of the invention to invention
And scope.So, if these modifications of the invention and modification belong to the claims in the present invention and its equivalent technologies scope it
Interior, then the present invention is also intended to including including these changes and modification.
