Abstract

一种可用于轻水反应堆核电站燃料组件的下管座过滤装置及防异物下管座，该下管座过滤装置(30)包括多片依次拼合的单元板(31)；拼合的相邻单元板(31)之间形成贯通的流体通道；流体通道包括多个分隔排列的直段流体入口(314)、多个分隔排列的直段流体出口(315)、及连通直段流体入口(314)和直段流体出口(315)的流体分通道(316)；中间位置的每一所述直段流体入口(314)的出口段分别与两个所述流体分通道(316)连通；中间位置的每一所述直段流体出口(315)的入口段分别与两个所述流体分通道(316)连通。利用直段流体入口、直段流体出口、流体分通道等，控制了冷却剂流向，防止产生不必要的涡流，使得压力损失得到有效控制；将大型的异物过滤后，进入流体分通道，通过将流体分通道再次过滤，实现了分段过滤，从而可以提高过滤效果。
