How to check the quality of the clamp type fluorine lined butterfly valve

     clamp-on Fluorine-lined Butterfly Valve It is a fluorine lined butterfly valve that adopts a clamp connection method. It is a new type of butterfly valve, also known as a fluoroplastic lined corrosion-resistant butterfly valve. It is made by molding (or embedding) polytetrafluoroethylene resin (or profiles processed) on the inner wall of steel or iron valve pressure parts (the same method is applicable to the inner lining of various pressure vessels and pipeline accessories) or the outer surface of valve internals, and using its performance in resisting strong corrosive media to make various valves and pressure vessels. At present, fluorine lined butterfly valves have been widely used in many fields such as petroleum, chemical, metallurgy, hydropower, etc. as an important component for realizing the on-off and flow control of pipeline systems. In addition, in the known butterfly valve technology, the sealing form mostly adopts a sealing structure, and the sealing materials are mostly good sealing materials such as rubber and polytetrafluoroethylene. Although this design can ensure the sealing performance of the valve, it is limited by structural features and cannot adapt to industries with high temperature, high pressure, strong corrosion, and high wear. There is currently a comparative fluorine lined butterfly valve, which is a three eccentric metal hard sealed butterfly valve. The valve body and valve seat are connected components, and the sealing surface layer of the valve seat is welded with heat-resistant and corrosion-resistant alloy materials. Multi layer soft stacked sealing rings are fixed on the valve plate. Compared with traditional butterfly valves, this butterfly valve has the advantages of high temperature resistance, easy operation, frictionless opening and closing, and compensating for sealing with the increase of torque of the transmission mechanism when closing, greatly improving the sealing performance and extending the service life of the butterfly valve.
in use Clamp type fluorine lined butterfly valve A quality inspection must be conducted beforehand, as a valve with poor quality can affect the operation of the entire pipeline system. The quality inspection of clamp type fluorine lined butterfly valves is usually divided into two categories: unboxing inspection and professional inspection. The unpacking inspection mainly involves checking the quantity, model, specifications, and whether there is any damage on the surface; Professional inspection involves conducting pressure tests and air tightness tests on valves. Only the unboxing inspection and professional inspection have passed Clamp type fluorine lined butterfly valve It is the valve with qualified quality.
