Where Should We Start The Quality Inspection Of Wafer-type Fluorine-lined Butterfly Valves?

Lined Butterfly Valve, also known as fluoroplastic lined corrosion-resistant butterfly valve, is a polytetrafluoroethylene resin placed on the inner wall of the steel or iron valve pressure-bearing part or the outer surface of the valve internals by molding or inlaying, and its performance in resisting strong corrosive media is used to make various valves and pressure vessels. Compared with 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 used and relatively cheaper.
The wafer-type fluorine-lined butterfly valve is a more common fluorine-lined butterfly valve. It has many advantages such as high temperature resistance, easy operation, no friction when opening and closing, and compensation for sealing when closing as the torque of the transmission mechanism increases. It improves the sealing performance of the fluorine-lined butterfly valve and extends its service life. It is widely used in various industries. The wafer-type fluorine-lined butterfly valve must pass the relevant quality inspection before it can be allowed to leave the factory. The quality inspection is generally divided into three elements: 1. Check whether the flange flange is worn; 2. Valve pressure test; 3. Determine the thickness of the lining.
