一种核电站盘根密封装置、泵及核电厂重要厂用水系统
摘要：
本实用新型公开了一种能防止其内壁受腐蚀的核电站盘根密封装置、泵、核电厂重要厂用水系统，其中盘根室密封装置包括腔体和盘根，所述盘根环设于所述腔体的内侧壁，所述腔体的内侧壁的表面附着有防腐蚀层，所述防腐蚀层与所述盘根紧密贴合。本实用新型中，由于核电站盘根密封装置的腔体的内壁表面增设有防腐蚀层，防止盘根盒腐蚀缺陷的发生，从而避免因腐蚀造成盘根密封失效的风险。
摘要（英）：

The utility model discloses a packing sealing device, a pump and a nuclear power essential service water system of a nuclear power plant. The inner wall of the packing sealing device can be prevented from being corroded. The packing sealing device comprises a cavity and packing. The packing is circularly arranged on the inner wall of the cavity, and a corrosion-resistant layer is attached to the surface of the inner wall of the cavity and closely fits with the packing. The corrosion-resistant layer is additionally arranged on the surface of the inner wall of the cavity of the packing sealing device of the nuclear power plant, so that the shortcoming of corrosion of a packing box is prevented, and risk of sealing failure of the packing due to corrosion is avoided.
