Development of Ceramic Valves 

The valves commonly used in various industries in China are metal valves. Metal valves have been used for hundreds of years. Although metal valves have undergone structural and material improvements, they cannot adapt to increasingly high wear and strong corrosion due to the limitations of metal material properties. The needs of other harsh working conditions are mainly reflected in the short service life and serious leakage, which greatly affects the stability of the system operation. Traditional metal valves are in urgent need of a complete innovation in materials, design and manufacturing processes.

The application of ceramic materials to industrial valves is a bold and beneficial innovation. 


The deformation of the ceramic material is very small.Ceramic valve has much higher bonding strength than metals. Generally, the crystal ion radius of ceramic materials is small, and the ionic electricity price is high, and the coordination number is large. These properties determine the tensile strength, compressive strength, elastic modulus of ceramic materials. The quantity and hardness are very high. However, the "brittleness" and difficult processing of the ceramic itself limit its application range. In the past ten years, due to the development and progress of martensitic transformation toughening technology, composite technology and nano-ceramic concept, the "ceramic" Brittleness" has been greatly improved, its toughness and strength have been greatly improved, and the range of applications has continued to expand.


In recent years, the application of new ceramic materials in petroleum, chemical, machinery and other fields has been very active. Using the wear resistance and corrosion resistance of ceramics to make wear-resistant and corrosion-resistant parts instead of metal materials has become an important part of the high-tech material market in recent years. one of the development directions.

 

The wear-resistant ceramic discharge valve is mainly used for the opening and closing of the gas and slag in the dry ash system of the power plant. For opening and closing on the side of the pipe. PG double gate air lock wear-resistant ceramic valve has good sealing performance, high temperature resistance, strong wear resistance, easy start, no sticking and ash accumulation, easy to use
