What aspects should be taken into account for quality inspection of clamp type fluorine lined butterfly valves

       Fluorine-lined Butterfly Valve Also known as fluoroplastic lined corrosion-resistant butterfly valve, it is a type of valve and pressure vessel made by molding or embedding polytetrafluoroethylene resin on the inner wall of steel or iron valve pressure parts or the outer surface of valve internals, utilizing its performance in resisting strong corrosive media. Compared to metal butterfly valves, fluorine lined butterfly valves have greatly improved corrosion resistance and wear resistance. In addition, fluorine lined butterfly valves are made of polymer materials, which are more widely available and relatively cheaper in cost.
But Clamp type fluorine lined butterfly valve It is a common type of fluorine lined butterfly valve, which has many advantages such as high temperature resistance, easy operation, frictionless opening and closing, and compensating for sealing with the increase of torque of the transmission mechanism when closing. It improves the sealing performance and extends the service life of fluorine lined butterfly valves, and is widely used in various industries. For clamp type fluorine lined butterfly valves, they must undergo relevant quality inspections before being allowed to leave the factory. Quality inspections can be roughly divided into three elements: 1. Check whether the flange flange is worn; 2. Valve pressure test; 3. Measure the thickness of the lining.
