Title:
MULTIFUNCTIONAL PROTECTION DEVICE FOR PIPELINE IN NUCLEAR POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2024/016918
Kind Code:
A1
Abstract:
Disclosed in the present invention is a multifunctional protection device for a pipeline in a nuclear power plant, the multifunctional protection device comprising an inner pressure bearing layer sleeved on the periphery of the pipeline for positioning and fixing the pipeline. The multifunctional protection device for a pipeline in a nuclear power plant is provided with a buffer layer, an absorption layer and an outer pressure bearing layer connected in sequence from inside to outside with the inner pressure bearing layer as the center, wherein the buffer layer comprises several hollow pipe bundle layers, the several hollow pipe bundle layers being connected around the inner pressure bearing layer to form the buffer layer; the absorption layer comprises several multi-gap portions which are mutually and alternately arranged, several small absorption layer pores being provided on each multi-gap portion; and the outer pressure bearing layer is arranged on the outermost layer of the multifunctional protection device for a pipeline in a nuclear power plant and is used for providing rigid support and preventing leakage in the pipeline . The multifunctional protection device can solve the problems of earthquake resistance, fracture and shock, thermal insulation and quantitative monitoring of medium leakage of an important pipeline in a nuclear power plant, and can replace a damper, an anti-shock limiting member, an anti-jet baffle, a liquid level monitoring device for a pit, etc., to ensure nuclear safety, optimize the design scheme, and reduce the economic cost of dealing with the problems in nuclear power engineering.
