Before people use the valve, they need to use clean water to carefully clean the inside of the pipeline, and pay attention to cleaning the inner wall of the water flowing through the valve, and remove all the iron filings and impurities hidden on the inner wall to prevent these impurities and harmful substances from entering the valve cavity and damaging the valve due to corrosion. After the pneumatic butterfly valve is closed, there are still some media objects inside the valve. These media objects accumulate inside the valve for a long time, which will cause greater pressure on the inner wall. The maintenance of the valve needs to be carried out according to certain procedures. First, find the cutting part in front of the valve, completely close the cutting part, and then open the valve to be repaired, Fully release the pressure inside the valve. If it is an electric valve or a steam valve, the power and steam need to be cut off in advance before the valve can be overhauled.
