Power station valves are control devices of the power station pipeline system, used to regulate or cut off the flow of media such as water and steam. Its cleaning frequency needs to be determined comprehensively based on the valve type, working environment and usage intensity.
\n1. Valve type
\nGate valve:
\nUnder normal working conditions, clean once every 2-3 years, focusing on cleaning the valve cavity sediment.
\nFrequent use or high temperature and high pressure working conditions, shorten the cleaning to 6 months-1 year (such as main steam pipeline valve).
\nBall valve\/butterfly valve:
\nClean medium, check and flush internal impurities every 1-2 years.
\nContaining particles or corrosive media, clean the valve seat and sealing surface every 3-6 months.
\nStop valve:
\nFor regulating flow, clean the valve core and valve seat every 1 year to prevent scale from affecting accuracy.
\n2. Working environment
\nHigh temperature and high pressure steam valve:
\nHigh temperature is prone to scaling, and it is recommended to flush the valve cavity scale every quarter to avoid blocking.
\nCorrosive medium valve:
\nBecause the medium is highly corrosive, it is necessary to clean and check the corrosion of the sealing surface every 3-6 months.
\nLarge flow\/high flow rate valves:
\nSince impurities are easily deposited, the valve body should be disassembled and flushed every year.
\n3. Other key scenarios
\nSafety valve\/check valve:
\nClean once every 6 months to ensure sensitive action.
\n\u200cSpare valves that have not been used for a long time:
\nClean thoroughly before activation to prevent rust slag from clogging.
\n\u200cSystems with poor water quality (such as hard water):
\nShorten cleaning to quarterly to reduce the impact of scale.<\/p>\n
