Excellent performance - Wear-resistant ceramic valves promotion
Chinese industries commonly used metal valves for valves, metal valves have been used on 100 years of history, although the metal structure of the valve through the material and improve, but the metal material property restrictions, can not meet the rising Wear and tear, corrosion, such as strong demand for harsh operating conditions, mainly in the short life, serious leaks have greatly affected the stability of the system. Traditional metal valves from the much-needed materials, design and manufacturing process for radical reforms in areas such as. Ceramic materials will be used in the valve industry is a bold and useful innovation. Deformation of ceramic materials is very small, much higher than the metal with a combination of strength, under normal circumstances, the composition of the ceramics of small radius of the ion crystal and plasma high-price, large coordination number, which determines the nature of the ceramic material tensile Strength, compressive strength, elastic modulus, hardness and so on, very high. However, the ceramic itself, “brittle” and difficult process limits the scope of its application in the past decade, due to the martensitic transformation toughening technology, composite materials and nano-ceramic technology Section of the concept of development and progress, has ceramic ” Fragile “greatly been improved, the toughness and strength has been greatly improved, expanding the scope of application.
In recent years, a new type of ceramic material in the petroleum, chemical, machinery and so on are very active in the field of application, the use of ceramic wear, decay and the production of wear resistant metal parts instead of the Department of materials, high-tech materials in recent years is an important market One of the development. Ceramic valves of the socio-economic benefits: 1. Ceramic valves using a new type of high-tech ceramic material structure of the valve seal parts and components of vulnerability, increased valve wear products, anti-corrosion and sealing, greatly extended the valve The life of the door. 2. The use of ceramic valves can be greatly reduced the number of the replacement valve repair and improve equipment operation system security, stability, saving the cost of repair equipment. 3. Ceramic valves can be used to improve the sealing of industrial piping systems, to reduce the maximum disclosure so as to protect the environment. 4. Ceramic manufacturing a wide range of raw materials, low-cost, aluminum, carbon, silicon, and other non-general will be able to create superior performance ceramic materials, can save a large number of rare metal materials and mineral resources. Wear-resistant ceramic valves are mainly used in electric power, petroleum, chemical, metallurgy, mining, waste water treatment industry, particularly in the face of high wear and tear, corrosion strong, high-temperature, high pressure, such as poor working conditions, ceramic valves have indicated that it is excellent Performance. Ceramic valves to meet the high wear and tear, corrosion strong use of the environment, in particular, is a prominent feature of the long service life, cost of the ceramic valves are far superior to other similar metal valve. With the continuous development of science and technology and progress, ceramics from the formula, forming, machining and assembly processes and other technology more mature and complete, ceramic valves for its outstanding performance has been a growing recognition of the valve industry . Manufacturers use the successful experience of ceramic valves can also be used to promote a wider field of engineering.
