What problems will be encountered during the use of clamp type fluorine lined butterfly valves

       Fluorine-lined Butterfly Valve It is a new type of butterfly valve, and fluorine lining is mainly used in highly corrosive working conditions. Fluoroplastics are lined on the areas where metal pressure vessels (valves, tanks, etc.) need to come into contact with strong corrosion to prevent corrosion of pressure vessels by highly corrosive media. Therefore, fluorine lined butterfly valves can be applied to pipelines with various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia, and various organic acids, strong acids, strong oxidants, and other corrosive media. However, due to the significant temperature limitations of fluorine lined butterfly valves, they are only suitable for ambient temperatures ranging from -50 ℃ to 150 ℃ Celsius.
However, fluorine lined butterfly valves are currently widely used in various industries such as petroleum, chemical, and metallurgy as components for achieving on/off and flow control in pipeline systems. In the current public butterfly valve sealing technology, most of the sealing forms of fluorine lined butterfly valves adopt sealing structures, using sealing materials with good sealing properties such as rubber and polytetrafluoroethylene. However, due to structural limitations, fluorine lined butterfly valves are not suitable for high-temperature and high-pressure industries. But Clamp type fluorine lined butterfly valve A fluorine lined butterfly valve using a clamp type connection method, in which the valve body and valve seat are integrally constructed, and high-temperature resistant materials are deposited on the sealing surface of the valve seat, and fixed to the valve plate by multiple layers of soft stacked sealing rings. Compared with ordinary fluorine lined butterfly valves, the clamp type fluorine lined butterfly valve has the advantages of high temperature resistance, convenient and labor-saving opening and closing process, and compensating for sealing with the increase of torque of the transmission mechanism during the first stage closing. It has received unanimous praise from the market and consumers.
