Description
Technical field
This utility model relates to a kind of reactor control rod and drives line shock test device, specifically refers to a kind of decoupling device driving line shock test for reactor control rod.
Background technology
Nuclear power station reactor control stick drives line to include drive mechanism, top guide cylinder, bottom guide cylinder and fuel assembly, C&P systems etc..In nuclear power designs, the critical component contained by Control rod drive line is antidetonation I kind equipment, needs during benchmark runs earthquake properly functioning, during safe shutdown earthquake can shutdown, therefore the anti-seismic performance of Control rod drive line is of crucial importance.
Owing to Control rod drive line has multiple spot to associate with reactor pressure vessel, therefore when coming earthquake, drive line all to have Seismic input at each relating dot, and the seismic (seismal of each relating dot is different.In order to mock-up reactor drives line seismic stimulation in real heap, reactor control rod drives line shock test to use excitation method.In shock test, it is desirable to have a simulation support means, water container can not only be provided for driving line, and can be for driving line transmission seismic (seismal.Owing to the horizontal earthquake load of each excitation point is different, in prior art, generally employing rigid conduit is as support, but the motion between each excitation point can be made to influence each other, and produces coupling, causes each to encourage the motion control accuracy of point to reduce.
Utility model content
The purpose of this utility model is to provide a kind of decoupling device driving line shock test for reactor control rod, to meet the requirement that reactor control rod drives line to decouple between each excitation point, make horizontal earthquake load between each excitation point interfere and minimize.
The purpose of this utility model is achieved through the following technical solutions:
A kind of decoupling device driving line shock test for reactor control rod, including about two stacked flanges, being connected by flexible pipe to inner side of two described flanges, the excircle of two flanges is fixed with multiple latch plate, and two flanges and flexible pipe are connected as an entirety by bolt, having the seal groove of annular on described flange medial wall, O RunddichtringO is placed in seal groove.This utility model is when reaction is to Control rod drive line excitation shock test, decoupling device is connected with other devices respectively by two flanges, by two flanges and be fixed on flexible pipe inside two flanges and coordinate to ban traditional rigid support tube, to avoid the motion between each excitation point caused because the horizontal earthquake load of each excitation point is different to influence each other, the coupling phenomenon of generation causes the motion control accuracy of each excitation point to reduce.Therefore, in shock test, this utility model provides a simulation support means for it, while flexible pipe is for driving line to provide water container, for driving line transmission seismic (seismal, on each excitation orientation, excitation point is decoupled simultaneously, concrete Uncoupled procedure is as follows, the two ends of multiple latch plates are bolted on the excircle of two flanges respectively, utilize the latch plate of the rectangle rigidity on its long side direction and short side direction big, the feature that rigidity in the thickness direction thereof is little, latch plate can be at vertical direction driven load, each excitation is decoupled by the thickness direction along latch plate simultaneously, make horizontal earthquake load between each excitation point interfere to minimize.Further, the seal groove of annular and O-ring seals with matching are set in ring flange medial wall, it is ensured that the proper flow of flexible liquid in pipe and do not leak, and then improve the stability of decoupling device.
Further, the long limit of described latch plate is parallel with the axis of described flexible pipe.As preferably, the long limit of latch plate is parallel with the axis of flexible pipe so that decoupling device, while for driving line by stable support, improves latch plate further to the interactional eradicating efficacy that moves between each excitation point.
This utility model compared with prior art, has such advantages as and beneficial effect:
1, this utility model achieves the decoupling between multiple excitation point at excitation orientation, it is ensured that the independence of each excitation experimental tests input；
2, this utility model uses latch plate to achieve the transmission of vertical direction load, and ensure that the stability of whole assay device；
3, simple in construction of the present utility model, processing is with easy for installation.
