Technical Problem

[0003]本实用新型目的在于提供一种核电站污染隔离区管线桥接集成装置，解决现有污染隔离方法无法保证在蒸汽发生器一次侧检修过程中气源线、电源线、仪控信号线及液压油管线使用过程中污染表面扩大的问题

Benefits of technology

[0011] Compared with existing technologies, the advantages of this utility model are as follows: This utility model provides an integrated bridging device for pipelines in a nuclear power plant's contaminated isolation zone. Firstly, the bridging base can divide the work area into a contaminated isolation zone and a non-contaminated isolation zone, allowing workers to connect the required interfaces in both zones separately, avoiding cross-contamination of pipelines on both sides. Secondly, the hydraulic oil pipe interface and compressed air interface are both quick-connect interfaces, and the power interface and instrumentation signal interface are simple to install, reducing the risk of prolonged exposure during operation.

Abstract

The utility model discloses a nuclear power plant pollution isolation area pipeline bridging integrated device relates to pipeline integrated tool technical field for solving the problem that the existing pollution isolation method cannot guarantee the pollution surface expansion in the use process of gas source line, power line, instrument control signal line and hydraulic oil pipeline in the primary side maintenance process of steam generator. The device comprises: the bridging device base for separating the pollution area and the non-pollution area, and the two side surfaces thereof are pollution isolation area panel and non-pollution isolation area panel respectively, and the pollution isolation area panel and the non-pollution isolation area panel are respectively provided with power interface, compressed air pipe interface, instrument control signal interface and hydraulic oil pipe interface. By using the device, the cross contamination of the pipelines on the two sides of the pollution isolation area and the non-pollution isolation area can be avoided.
