Fluorine-lined Check Valve Material Process Introduction

With the rapid development of industry, my country's fluorine-lined valve market is very important in the industrial process. Fluorine-lined check valve is a valve that uses fluorine-lined material as the lining and metal wrapped on the outside. It is a valve with excellent corrosion resistance. At present, there are more than ten kinds of lining materials for fluorine-lined check valves used in my country, such as polytetrafluoroethylene, polyvinylidene fluoride, polytrifluoroethylene, and polyperfluoroethylene. These materials have good corrosion resistance. Acids, alkalis, and salts will not cause corrosion to them, so they are suitable for manufacturing lining materials for fluorine-lined check valves.
When making Lined Check Valve, the polysoluble tetrafluoroethylene material is generally flattened in the mold cavity of the fluorine-lined check valve, such as the valve seat and valve plate. The fluorine-lined check valve produced in this way is fast and good. One defect is that it will bulge and expand after heating. There are many kinds of manufacturing processes for fluorine-lined check valves, such as loose lining molding technology, winding molding technology, composite molding technology, etc. The good use of these technologies will bring unexpected benefits to the molding of fluorine-lined check valve products.
