Wafer Double Disc Ceramic Gate Valve WCB

The Wafer Double Disc Ceramic Gate Valve commonly used in various industries in China are metal valves, which have been used for hundreds of years. Although the metal valves have been improved in structure and materials, due to the limitations of metal material properties, they cannot meet the requirements of increasingly high wear, strong corrosion and other severe working conditions, mainly reflected in the short service life, and the leakage has seriously affected the stability of the system operation.

The deformation of Wafer Double Disc Ceramic Gate Valve is very small, which has much higher mechanical strength than metal. Generally, the radius of crystal ions that make up ceramic materials is small, and the ion electricity price is high, and the coordination number is large. These properties determine that the tensile strength, compressive strength, elastic modulus, hardness, etc. of ceramic materials are very high. However, the "brittleness" and difficult machining of ceramics limit its application scope. In recent ten years, due to the development and progress of martensitic transformation toughening technology, composite material technology and nano ceramic concept, the "brittleness" of ceramics has been greatly improved, its toughness and strength have been greatly improved, and its application scope has been continuously expanded. In recent years, the application of new ceramic materials in petroleum, chemical industry, machinery and other fields is very active. It is one of the important development directions of high-tech materials market in recent years to use the wear resistance and corrosion resistance of ceramics to make wear resistant and corrosion resistant parts instead of metal materials
