Application of large-diameter ventilation electric butterfly valve in industrial valve

by:Sino Valves     2021-03-20
At present, metal valves are commonly used in the production of various industries in our country. Metal valves have been used for hundreds of years. Although the structure and materials have been improved during this period, they are more and more unable to adapt to the conditions of the metal materials. The needs of harsh working conditions such as wear and strong corrosion. Mainly reflected in the short service life, serious leakage greatly affects the stability of system operation. Traditional metal valves are in urgent need of thorough innovation in terms of materials, design and manufacturing processes. The application of large-diameter vent butterfly valves in industrial valves. Advanced ceramic materials, as new materials in the 21st century, have been valued by more and more scientists. Applying it to industrial valves is a bold and beneficial innovation. The amount of deformation of ceramic materials is very small, and the bonding strength is much higher than that of metals. Generally, the ionic radius of the crystals that make up ceramic materials is small, and the ion electricity price is high, and the coordination number is large. These properties determine the tensile strength and Compressive strength, elastic modulus, hardness, etc. are all very high. However, the “brittleness” and difficult processing of ceramics limit its application range. In the past ten years, due to the development and progress of martensitic transformation toughening technology, composite material technology and nano-ceramic concepts, the 'Brittleness' has been greatly improved, its toughness and strength have been greatly improved, and the scope of application has been continuously expanded. Wear-resistant ceramic valves are mainly used in electric power, petroleum, chemical, metallurgy, mining, sewage treatment and other industrial fields, especially in the face of high wear, strong corrosion, high temperature, high pressure and other harsh working conditions, and show its excellent performance. It can meet the use environment of high wear and strong corrosion, especially the outstanding feature is the long service life, and its performance-price ratio is far superior to other similar metal valves. With the continuous development and advancement of science and technology, ceramic materials have become more mature and complete in terms of formulation, molding, processing and assembly technology. Ceramic valves are increasingly recognized by the industry for their excellent performance. The successful experience of making ceramic valves can also be applied to a wider range of engineering fields.
