What Problems Will Be Encountered During The Use Of Wafer-type Fluorine-lined Butterfly Valves?

Lined Butterfly Valve is a new type of butterfly valve. Fluorine lining is mainly used in strong corrosion conditions. Fluorine plastics are lined in places where metal pressure vessels (valves, tanks, etc.) need to be in contact with strong corrosion to prevent strong corrosive media from corroding pressure vessels. Therefore, fluorine-lined butterfly valves can be used in pipelines of various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, strong oxidants and other corrosive media. However, due to the large temperature limitations of fluorine-lined butterfly valves, they are only suitable for ambient temperatures of -50℃~150℃ Celsius.
However, fluorine-lined butterfly valves are currently used as a component to realize the on-off and flow control of pipeline systems in many industries such as petroleum, chemical industry, and metallurgy. In the current public butterfly valve sealing technology, most of the sealing forms of fluorine-lined butterfly valves adopt a sealing structure, and use rubber, polytetrafluoroethylene and other sealing materials with good sealing properties. However, due to the limitations of structural characteristics, fluorine-lined butterfly valves are not suitable for high temperature and high pressure industries. The wafer-type fluorine-lined butterfly valve is a fluorine-lined butterfly valve that adopts a wafer-type connection. The valve body and valve seat are constructed in one piece. The high-temperature resistant material is welded on the sealing surface of the valve seat, and it is fixed to the valve plate by a multi-layer soft stacking seal ring. Compared with ordinary fluorine-lined butterfly valves, the wafer-type fluorine-lined butterfly valve has the advantages of high temperature resistance, convenient opening and closing process, labor-saving, and compensating the seal as the torque of the transmission mechanism increases when the first level is closed. It has been well received by the market and consumers.
