Abstract
The invention particularly relates to a nuclear power plant sodium hypochlorite adding pipeline connecting structure which comprises a sodium hypochlorite adding pipeline, a pipeline fixing device and a living water main pipeline, wherein a through hole is formed in the pipe wall of the upper side of the living water main pipeline; the lower end of the pipeline fixing device is welded to the outer surface of the upper side pipe wall of the living water main pipeline, and a pipe opening of the pipeline fixing device is communicated with the through hole; and one end of the sodium hypochlorite adding pipeline sleeved in the pipeline fixing device penetrates through the pipeline fixing device and the through hole and then extends into an inner cavity of the living water main pipeline. According to the nuclear power plant sodium hypochlorite adding pipeline connecting structure, medicine accumulation in the sodium hypochlorite adding pipeline can be effectively inhibited, the corrosion resistance of the joint of the sodium hypochlorite adding pipeline and the living water main pipeline is remarkably improved, and site construction and installation are convenient.
Description
technical field [0001] The invention relates to the technical field of anti-corrosion technology for nuclear power plant equipment, in particular to a connection structure for a sodium hypochlorite dosing pipeline in a nuclear power plant. Background technique [0002] The sodium hypochlorite dosing pipeline of the nuclear power plant continuously adds sodium hypochlorite to the main pipeline of domestic water to ensure the production quality of domestic water. If there is leakage in the sodium hypochlorite dosing pipeline of the nuclear power plant, it will affect the quality of living water. At the same time, when the defect is dealt with, the corresponding system will be isolated and shut down, which will affect the cooling water supply of the corresponding key equipment of the nuclear power plant. Contents of the invention [0003] Based on this, it is necessary to provide a sodium hypochlorite dosing pipeline connection structure for a nuclear power plant sodium hypoc...
