为详细说明本申请的内容、构造特征、所实现目的及效果，以下结合实施方式并配合附图详予说明。
请参阅图1至3，本申请公开了一种用于控制棒驱动线的热态试验装置，包括底部连接壳1、下部承压壳2、中部承压壳3、上部承压壳4、下堆芯板5、围板组件6、上堆芯板7、导向筒支撑板8、导向筒9、管座安装结构10以及用于安装控制棒驱动机构的管座0。底部连接壳1、下部承压壳2、中部承压壳3及上部承压壳4依次密封连接，下部承压壳2的两端分别形成有下板安装止口21和上板安装止口22，下堆芯板5固定在下板安装止口21，围板组件6位于下部承压壳2内且固定在下堆芯板5上，围板组件6于靠近其顶部的位置沿周向设有多个围板调节件61，借由对围板调节件61的伸缩调节和围板调节件61与下 部承压壳2的内侧壁的抵接使围板组件6相对下堆芯板5对中，上堆芯板7固定在上板安装止口22，上堆芯板7沿其周向设有多个上板调节件71，借由对上板调节件71的伸缩调节和上板调节件71与上板安装止口22的内侧壁的抵接使上堆芯板7相对下堆芯板5对中，中部承压壳3的上端形成有支撑板安装止口31，导向筒支撑板8固定在支撑板安装止口31，导向筒支撑板8沿其周向设有多个支撑板调节件81，借由对支撑板调节件81的伸缩调节和支撑板调节件81与支撑板安装止口31的内侧壁的抵接使导向筒支撑板8相对下堆芯板5对中，管座安装结构10放置在上部承压壳4的上端。具体而言，下堆芯板5、上堆芯板7及导向筒支撑板8分别通过紧固螺钉靶合在下板安装止口21、上板安装止口22及支撑板安装止口31，其中上堆芯板7及导向筒支撑板8需利用配钻定位，围板组件6的下端通过从下堆芯板5装入的紧固螺钉与下堆芯板5固定；导向筒9的上部位于上部承压壳4内，下部位于中部承压壳3内，且导向筒9固定在上堆芯板7上以使导向筒9可在导向筒支撑板8和上堆芯板7的协同下实现可靠固定。
本申请的用于控制棒驱动线的热态试验装置的承压壳采用分段式设计，单个分段承压壳较短，分段承压壳之间的配合端面间的平行度及其筒体壁面与配合端面之间的垂直度更容易保证，加工工艺更简单，加工精度和加工难度大大降低，生产成本进一步降低；而且，通过设置围板调节件61、上板调节件71及支撑板调节件81，进而能够通过围板调节件61、上板调节件71及支撑板调节件81的伸缩调节实现围板组件6、上堆芯板7和导向筒支撑板8以下堆芯板5为基准的对中调节，上述对中调节结构简单，调节方式简单而可靠。
在一些实施例中，上板调节件71、支撑板调节件81及围板调节件61为调节螺丝，结构非常简单，在进行对中调节时，只需对调节螺丝进行旋进、旋出操作即可，调节方式简单、方便而可靠。在一具体的实施方式中，围板组件6之间围成正方形状，围板组件6的每侧围板62的顶部位置分别固设有一个调节螺丝，相邻的调节螺丝之间呈90度夹角。
在一些实施例中，底部连接壳1包括底壳套筒部11及形成在底壳套筒部11的上端的底壳上法兰12，下部承压壳2包括下壳套筒部23及形成在下壳套筒部 23的两端的下壳下法兰24和下壳上法兰25，中部承压壳3包括中壳套筒部32及形成在中壳套筒部32的两端的中壳下法兰33和中壳上法兰34，上部承压壳4包括上壳套筒部41及形成在上壳套筒部41下端的上壳下法兰42。下壳下法兰24与底壳上法兰12配钻定位，中壳下法兰33与下壳上法兰25配钻定位，上壳下法兰42与中壳上法兰34配钻定位，下板安装止口21、上板安装止口22及支撑板安装止口31分别形成在下壳下法兰24、下壳上法兰25及中壳上法兰34。通过法兰之间的配钻定位，便于各壳之间进行对中，同时也有利于拆卸后复装的对中效果。
在一些实施例中，底壳上法兰12与下壳下法兰24之间，下壳上法兰25与中壳下法兰33之间，以及中壳上法兰34与上壳下法兰42之间分别设有金属O圈(图未示)。通过上述设计，能够保证法兰面之间的绝对平行度，保证试验装置的直线度；也可以保证法兰面直接接触，保证试验装置内各试验件在轴向方向上各相对位置的准确性，增加试验数据的可靠性；而且，还有利于试验装置承受高温和高压环境下的试验要求。
在一些实施例中，底部连接壳1、下部承压壳2、中部承压壳3及上部承压壳4为不锈钢锻件；通过该设计，有利于试验装置承受在高温、高压环境下的试验以便于进行冷热态等全工况、长周期的试验研究。在具体的实施方式中，底部连接壳1、下部承压壳2、中部承压壳3及上部承压壳4的套筒部和相互间的法兰均为不锈钢锻件。
在一些实施例中，围板组件6于围板调节件61下方沿其轴向设有多组辅助支撑件63，每组辅助支撑件63沿围板组件6的周向分布且相对下部承压壳2的内侧壁间隙设置。通过该设计，在围板组件6发生倾斜时，借由辅助支撑件63与下部承压壳2之间的抵接，能够对围板组件6起到支撑的作用。
在一些实施例中，管座安装结构10为压块，贴合压放在上部承压壳4的顶端，压块可相对上部承压壳4作任意水平方向上的位置调节；通过依靠压块自身的重力进行定位，在进行拆卸时，可以直接拿取，无需进行紧固件等的拆除，提高了试验效率；而且，由于压块可相对上部承压壳4作任意水平方向上的位置调节，也便于对管座0进行对中调节。具体而言，压块与底部连接壳1、下部 承压壳2、中部承压壳3及上部承压壳4均采用不锈钢锻件以使试验装置更好地承受高温、高压的试验环境，进而更好地进行冷热态等全工况的试验研究。
作为优选的实施方式，上部承压壳4的顶端形成有压块安装止口43，压块压放在压块安装止口43，压块安装止口43的尺寸大于压块的尺寸以使压块可相对上部承压壳4作任意水平方向上的位置调节。具体而言，上部承压壳4的上端形成有上壳上法兰44，压块安装止口43形成在上壳上法兰44上。

在将下堆芯板5固定在下部承压壳2的下板安装止口21之后，用于控制棒驱动线的热态试验装置的对中方法还包括将下堆芯板5配钻定位在下部承压壳2的步骤，以便于以后复装。
综上，本申请的用于控制棒驱动线的热态试验装置设置有围板调节件61、上板调节件71及支撑板调节件81，进而能够通过围板调节件61、上板调节件71及支撑板调节件81的伸缩调节实现围板组件6、上堆芯板7和导向筒支撑板 8以下堆芯板5为基准的对中调节，上述对中调节结构简单，调节方式简单而可靠。另外，通过在底壳上法兰12与下壳下法兰24之间，下壳上法兰25与中壳下法兰33之间，以及中壳上法兰34与上壳下法兰42之间分别设有金属O圈，能够保证法兰面之间的绝对平行度，保证试验装置的直线度；也可以保证法兰面直接接触，保证试验装置内各试验件在轴向方向上各相对位置的准确性，增加试验数据的可靠性；而且，还有利于试验装置承受高温和高压环境下作业。此外，由于底部连接壳1、下部承压壳2、中部承压壳3及上部承压壳4为不锈钢锻件，便于试验装置承受在高温、高压环境下的作业。再者，本申请的管座安装结构10采用压块形式，依靠压块自身的重力进行定位，可以直接拿取，提高了试验效率；而且，由于压块可相对上部承压壳4作任意水平方向上的位置调节，也便于对管座0进行对中调节。本申请的用于控制棒驱动线的热态试验装置的对中方法能够实现简单而可靠的对中作业，而且通过相关结构之间的配钻定位，使得试验装置在拆卸后具有优秀的复装性能，同时也便于试验装置的检验。
以上所揭露的仅为本申请的较佳实例而已，其作用是方便本领域的技术人员理解并据以实施，当然不能以此来限定本申请之权利范围，因此依本申请申请专利范围所作的等同变化，仍属于本申请所涵盖的范围。
