摘要
Abstract
Due to the corrosion of the volute disc-shaped drainage valve in the Rudila Power Plant,the frequency of maintenance cycles has also increased,which affects the operational stability of the volute disc-shaped valve.Through analysis,it can be concluded that the main reasons for the leakage of water in the upper part of the snail shell disc valve and the high relative humidity in the environment are identified.By improving the working environment of the snail shell disc valve to circulate dehumidification of air and designing a new type of snail shell disc valve drawer type drainage device,the corrosion phenomenon of the snail shell disc valve has been completely eliminated,the production cost of the snail shell disc valve has been reduced,and the reliability of operation has been improved.关键词
