New ceramic valve technology innovation

Metal valves are prone to cracks when used for a long time, and ceramic valves do not. Due to the wear resistance, corrosion resistance and tight sealing, the ceramic water valve is very water-saving. Ceramic valves can be used 500,000 times. If you switch 60 times a day, you can use 22.8 years, which is impossible with metal valves. At present, the valves commonly used in the production of various industries in China are metal valves. The use of metal valves has been in the history of hundreds of years. Although the structure and materials have been improved, they are increasingly unable to adapt to the high conditions of metal materials. The need for harsh working conditions such as wear and strong corrosion is 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 radical innovation in materials, design and manufacturing processes. The appearance of ceramic valves has largely filled the application gaps that metal valves cannot achieve. The ceramic material has a small deformation amount and a much higher bonding strength than the metal. Generally, the crystal ionic radius of the ceramic material is small, and the ion electricity price is high, and the coordination number is large. These properties determine the tensile strength of the ceramic material, The compressive strength, modulus of elasticity, hardness, and the like are very high. However, the "brittle" and difficult processing of ceramic itself limits its application range. In the past decade, due to the development and progress of martensitic transformation toughening technology, composite technology and nano-ceramic concept, ceramics have been made " The brittleness has been greatly improved, its toughness and strength have been greatly improved, and the scope of application has been continuously expanded. The main features of ceramic valves: 1. The use of high-tech new ceramic structural materials to make the valve's sealing parts and wearing parts, improve the wear resistance, corrosion resistance and sealing of the valve products, greatly extending the service life of the valve. 2. The use of ceramic valves can greatly reduce the number of maintenance and replacement of valves, improve the safety and stability of the supporting equipment operating system, reduce the labor intensity of workers, and save equipment repair costs. 3. The use of ceramic valves can improve the sealing of industrial piping systems, and at the same time minimize the leakage, which will play an active role in promoting environmental protection. 4. The raw materials for manufacturing ceramics are wide, the cost is low, and ordinary ceramics such as aluminum, carbon, silicon, etc. can be used to manufacture ceramic materials with superior performance, which can save a lot of metal materials and rare mineral resources. The precision machining of special ceramics is an internationally recognized high-tech technology. We independently research and develop, modify the equipment, and innovate dozens of unique precision ceramic grinding methods, producing ceramic shafts, ceramic grinding cores, and daily-use ceramic drills. Such high-tech products quickly seized the international market. It is worth mentioning that the production process of special ceramics is non-polluting, and all the waste products produced can be recycled. The main raw material alumina is the most abundant in the earth's crust. Put the soil inside, which has 25% alumina. With the continuous development and advancement of science and technology, the technology of ceramic material formulation, molding, processing and assembly process has become more mature and complete. Ceramic valves have been recognized by the industry for their excellent performance.
