Background technology
Fuel assembly is the critical component of nuclear reactor, its produce heat energy and by this thermal energy transfer to cooling medium.Skeleton is the main support parts of fuel assembly, axially runs through whole fuel assembly by some guide pipes wherein, bears the axial load from upper and lower part and fuel assembly inside.Upper base is the upper interface parts of fuel assembly, plays the functions such as protection and location, top simultaneously.Guide pipe and upper base link together by web member
At present main PWR fuel assembly all adopts removable guide pipe and upper base stud connector design in the world, so that heap internal combustion charge bar can be dismantled upper base refuelling rod easily by operated from a distance instrument while damaging.These stud connector designs also provide different locking modes in guaranteeing dismoutability and enough strength of joint, prevent under running environment, connecting self to throw off and losing efficacy in operation, transport and heap.
Taking the AP1000 of US Westinghouse company type fuel assembly as example, after guide pipe is fixedly connected with upper base Inserting Tube machinery, Inserting Tube projection forms releasable connection with the groove fit of upper base guiding pore, stick into bossing root by locking tube, prevent that its radial shrinkage from deviating from groove, form the removable connection of locking.Russia VVER fuel assembly is realized removable connection by guide pipe with the elastic card pipe that inserts upper base after collar welding.Above-mentioned technical battery fitting is too much, complicated operation.
Summary of the invention
The object of the invention is the defect in order to overcome prior art, a kind of removable connecting-piece structure is provided, realize the reliable connection between base and guide pipe on fuel assembly, this structure should prevent from Joint failure occurring or getting loose while operation in fuel assembly operation transport and heap, can be dismantled easily and be reset by operated from a distance instrument when needed simultaneously.
To achieve these goals, technical scheme of the present invention is, the removable guide pipe of a kind of rotation-upper base web member, comprises spinner cap and spinner sleeve pipe, and the two is circular tube structure, closely cooperates each other and connects by spinner structure; Wherein, the top of spinner cap is elasticity shirt rim, and middle and lower part, elasticity shirt rim is provided with semi-cylindrical hill; On elasticity shirt rim, circumferentially evenly have several longitudinal grooves, elasticity shirt rim is divided into some lobes by longitudinal groove; The inner face bottom of spinner cap, along being circumferentially evenly equipped with the protruding spinner buckle identical with spinner line quantity, has vertically some operation-interfaces between elasticity shirt rim and spinner buckle; The external wall of upper portion of spinner sleeve pipe, along being circumferentially evenly arranged the spinner line and the catching groove that mate with the spinner buckle of spinner cap, forms spinner structure with spinner buckle; The bottom of spinner sleeve pipe is provided with guide pipe interface.
Described spinner line has 6, and spinner buckle has 6.
On described elasticity shirt rim, circumferentially evenly have 4～7 longitudinal grooves, be preferably 5.
In spinner structure between described spinner cap, spinner sleeve pipe, spinner card is circumferentially arranged in to spinner sleeve outer wall upper end equably, in spinner cap inwall bottom, spinner line, spinner groove is circumferentially set accordingly.
In order to reduce component processing cost, the company's mode between described spinner cap, spinner sleeve pipe can also adopt engage thread to connect.
Beneficial effect of the present invention is as follows: by distinctive spinner structure with loosen design and realize the reliable connection between base and guide pipe on fuel assembly, be convenient to when needed operated from a distance simultaneously and remove.This web member relies on mechanical system to connect and pass through elasticity locking, does not substantially produce plastic deformation, and installing/dismounting can not damage web member and the generation of upper base.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
The removable guide pipe of a kind of rotation-upper base web member, as shown in Figure 1 and Figure 2, comprises spinner cap 13 and spinner sleeve pipe 14, and the two is circular tube structure, closely cooperates each other and connects by spinner structure; Wherein, the top of spinner cap 13 is elasticity shirt rim 1, and 1 middle and lower part, elasticity shirt rim is provided with semi-cylindrical hill 12; On elasticity shirt rim 1, circumferentially evenly have 5 longitudinal grooves 11, longitudinal groove 11 is divided into some lobes to increase elasticity by elasticity shirt rim 1, and elasticity shirt rim 1 can inwardly be shunk in the time being subject to certain power; The inner face bottom of spinner cap 13, along being circumferentially evenly equipped with 6 protruding spinner buckles 2, being sexangle and being evenly distributed on edge under spinner cap 13 inwalls, as the interface of spinner structure; Between elasticity shirt rim 1 and spinner buckle 2, have vertically some operation-interfaces 3, apply turning moment for operated from a distance instrument, screw spinner cap 13, make the semi-cylindrical hill 12 of elasticity shirt rim 1 clamp-on guiding pore groove 9, realize the interlocking with spinner structure; This connection is thrown off, need certain opposing torque, while needing dismounting, only need apply certain reverse rotation moment to spinner cap 13 from operation-interface 3; In fuel assembly operation, transport and heap, under running environment, be carried on spinner cap 13 phenomenon that can not meet accident and without opposing torque; The external wall of upper portion of spinner sleeve pipe 14, along being circumferentially evenly arranged the spinner line 4 and the catching groove 5 that mate with the spinner buckle 2 of spinner cap 13, forms spinner structure with spinner buckle 2; The bottom of spinner sleeve pipe 14 is provided with guide pipe interface 6.In another embodiment, the spinner structure between spinner cap 13, spinner sleeve pipe 14, for spinner buckle 2 is circumferentially arranged in to spinner sleeve pipe 14 outer wall upper ends equably, circumferentially arranges spinner line 4, spinner groove 5 accordingly in spinner cap 13 inwall bottoms.
In order to reduce component processing cost, the company's mode between spinner cap 13, spinner sleeve pipe 14 can also adopt engage thread to connect.
As shown in Figure 3, when installation, guide pipe 8 and spinner sleeve pipe 14 are fixedly connected with the lead counterbore of pore bottom of base lattice plate 7 in rear insertion by welding or mechanical system, spinner cap 13 inserts guiding pore from upper end, the spinner buckle 2 of spinner cap 13 inserts in the corresponding spinner groove 5 of spinner sleeve pipe 14, by applying turning moment, make spinner buckle 2 screw in spinner groove 5 depths, spinner cap 13 and spinner sleeve pipe 14 clamp guiding pore boss 10; Meanwhile, the semi-cylindrical hill on elasticity shirt rim 1 is also clamp-oned in guiding pore groove 9, and 13 axially-movables of restriction spinner cap, prevent from getting loose, as shown in Figure 4.
After installation, as shown in Figure 5, during due to the interior operation of heap, upper base lattice plate 7 and guide pipe 8 can not relatively rotate effect, and spinner cap 13 can not be subject to turning moment yet, therefore can not connect and can automatically throw off.While needing dismounting, only need retrograde rotation that elasticity shirt rim 1 projection is extruded to guiding pore groove 9, spinner cap 13 is extracted.
Above embodiments of the invention are explained in detail, above-mentioned embodiment is only optimum embodiment of the present invention, but the present invention is not limited to above-described embodiment, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from aim of the present invention, make various variations.
