Description
Technical field
This utility model is related to a kind of portable nuclear reactor structure forging, more particularly to portable nuclear reactor steam is sent out
Raw device low head forging slab part.
Background technology
Portable nuclear reactor vaporizer is one of critical component of compressed water reactor nuclear power nuclear island, its steam generator low head
It is that the maximum important feature part of pressure reduction is undertaken in steam generator again, plays a part of to seal and isolate one, secondary circuit coolant,
And primary Ioops side coolant flow through tube bank before and after collect chamber, it contains coolant entrance pore, outlet opening and two
Individual manhole, two manholes collect chamber with two of low head respectively and are connected.Therefore steam generator low head is in hemisphere
Two pore seats and two manhole collars are provided with coronal end socket main body, belong to slab block member, forging difficulty is very big, and
And the characteristics of due to miniature movable type nuclear reactor, require that pore seat and its joint pipe structure that is attached thereto are compact again, with more
For rational locus.
End socket main body is spliced by welding method by existing low head with pore seat and manhole collar, therefore
And end socket main body can not form complete metal streamline with stub (tube), manhole collar.Stub (tube) and manhole collar in end socket main body is again
It is to stretch out along the radial direction of end socket spherical crown, does not only take up more vaporizer peripheral spaces, and be more easy to cold
But turbulent flow is formed in agent collection chamber, is aggravated the formation of alternate load and pipeline vortex, is caused the not uniform stress concentration of stress distribution,
Fatigue, creep and damage are produced easily.Therefore not only welding procedure is complicated for existing nuclear reactor vaporizer low head, steady quality
Property is poor, and yield rate is low, and unreasonable in structure, has both increased taking up room for vaporizer, exacerbates low head high temperature again
Stress mutation under the severe ruuning situation of high pressure.
In order to improve the voltage endurance capability of low head finished product, the complete of metal structure streamline is realized, while its structure will be made more
For compact, take up room less, first-selected fabrication and processing approach is that solid forging goes out pore seat and manhole collar in end socket main body,
And pore seat direction inwardly will be closed up as far as possible, and manhole collar can be towards outside, i.e., pore seat can not be consistent with the direction of manhole collar
Towards outside, the compact of structure space could be realized.The requirement of this spline structure more brings difficulty to the solid forging of end socket, therefore
The low head slab for designing Rational structure is the key point for producing low head qualified products.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of mobile heap vaporizer low head slab, is not only convenient for
The overall final shaping unit of low head, and the metal structure of newly net forming product can be made uniformly closely knit, space structure is compact.
In order to solve above-mentioned technical problem, mobile heap vaporizer low head slab of the present utility model, including slab main body,
The slab main body is in discoideus structure, and the one side of the slab main body is provided with two pore round platforms and two manhole round platforms；
The another side of slab main body is provided with deformation circumference turned-down edge and deformation central boss, cardiac prominence in the deformation circumference turned-down edge and deformation
Platform is respectively positioned at periphery and the center of place slab main body plate face, plate face of the manhole round platform perpendicular to slab main body
On, the pore round platform is then obliquely arranged in the plate face of slab main body.
After using said structure, as in end sealing plate blank main body, solid forging goes out pore round platform and manhole round platform, the knot
The slab of structure is more convenient for the punch forming of the nearly finally finished of end socket, it is ensured that being greatly improved for low head finished product mechanical property, more can
The bad working environments formed by the High Temperature High Pressure and alternate load and vapor vortex of steam generator are born, is conducive to end socket to work
The raising of the homogenization and safety in operation of stress；And by the solid forging of manhole round platform, pore round platform and end socket main body
Both metal structure had further been refined, had been conducive to the accurate forming of manhole collar and pore seat again so that end socket main body and manhole collar,
Metal streamline between pore seat is smooth coherent and consistent with forging profile to greatest extent.Again as manhole round platform is vertical
It is arranged in the plate face of slab main body, and pore round platform is rolled and is tiltedly arranged in the plate face of slab main body, rushes in discoideus base
During being pressed into the spherical crown shape low head at nearly end, vertically disposed manhole round platform is then progressively outward-dipping so that nearly whole manhole
It is easy to operating observation to safeguard and normal service；And the pore round platform being obliquely installed then progressively inwardly closes up, ultimately form perpendicular
Straight pore round platform, the adapter being so connected on pore round platform extend along the short transverse of vaporizer, without to vaporizer
Around expand extension, effectively reduce taking up space for vaporizer, make structure more reasonable, take up space less；Simultaneously
Vertical pore round platform, is more beneficial for the heating surface bank that coolant is swimmingly flowed into or from tube sheet, and not only flow resistance is little,
And the formation being vortexed in reducing light pipeline, the favourable generation for reducing alternate load and non-homogeneous stress.Due also to slab main body
Another side be provided with deformation circumference turned-down edge and deformation central boss, deformation central boss is preced with striking out for low head in nearly end bulb
During type, the middle part metal of end sealing plate blank can flow to periphery from middle part in punching press, so as to ensure the reasonable of metal streamline
It is basically identical with hemisphere blank thickness, the newly net forming processing in rear road is not only contributed to, and causes longitudinal mechanics of forging
Performance and horizontal mechanical performance are significantly improved；During nearly end punch forming, the steel slab surface of die-punch pressure
Progressively recessed, surface metal-layer, so as to fill the metal at deformation circumference turned-down edge therefore is arranged radially to perimeter along slab
Deformation turned-down edge in the same direction is more conducive to the formation of the nearly finally finished of end socket.
Preferred implementation of the present utility model, the manhole round platform and pore round platform are the frustum of a cone, the pore circle
Position inclined angle alpha=60 ° of platform.The round platform cone angle of the manhole round platform and pore round platform is 20 °, and the manhole round platform is provided with
Round platform core bore.Ensure that the newly net forming of end socket, and the smooth demoulding in punching course.
