一种凝汽器泄漏管排定位设备

Abstract

本实用新型属于凝汽器泄漏检测技术领域，尤其为一种凝汽器泄漏管排定位设备，定位设备固定于凝汽器壳体的至少一端，用于对管排件进行泄漏检测定位；定位设备包括滑动在凝汽器壳体内部的两个移动板，凝汽器壳体的内部设置有用于驱动两个移动板同步反向移动的驱动机构。本实用新型通过堵头对管排件中铜管的两端进行封堵，随后对其内部充气后并进行保压，由于管排件中的铜管充气后进气管上的气囊便会鼓起，因此在保压过程中，如若管排件中的哪根铜管发生泄漏，此时其相对应位置进气管上的气囊便会泄气，从而使得工作人员在不进入凝汽器的内部时也能够快速对发生泄漏的铜管进行查找定位，以便于后续对其进行维修。
