At present the production of various industries in China commonly used in the valve metal valve, metal valve used have had a hundred years, during which although Ye Jing Guo structure and material improvements but Shou Jin Shu Cai Liao own conditions restrictions, an increasing can not adapt to high wear, high corrosion bad condition, needs. Mainly in short service life, greatly affected the disclosure of a serious system stability. Traditional metal valves needed from materials, design and manufacturing processes, etc. overhaul. Advanced ceramic materials as the twenty-first century, new mate
rials, has been more and more valued by scientists, it is a bold used in industrial valves and useful innovation.

Deformation of ceramic materials is very small, much higher than the metal with a combination of strength, generally composed of ceramic materials under the crystal ionic radius and ion price high, a large coordination number, the nature of tensile strength of ceramic materials , compressive strength, elastic modulus, hardness and so very high. Ceramic itself, however, the "brittle" and difficult to machine limits its scope of application of the last decade, due to martensitic transformation toughening technology, composite materials and nano-ceramic Branch Technical development of the concept and progress has been made ceramics " brittle, "has been greatly improved, its toughness and strength has been greatly improved, ever-expanding range of applications.In recent years, new ceramic materials in petroleum, chemical, mechanical, and other fields is very active, using ceramic wear resistance, corrosion resistance and production of wear parts to replace metal materials corrosion is an important market in recent years high-tech materials development directions.

Ceramic Application Process Required to Address the Following Key Issues:

To solve the problem of brittle ceramics, ceramic toughness increase; control shrinkage, increase the rate of ceramic materials fired products; developed high-temperature kiln; developed ceramic processing equipment; achieve ceramic pieces and metal body with precision. Tianjin Shengkai Industrial Technology Development Co., Ltd. on the above key issues, conducted research, and resolved. After the test batch production, in electricity, metallurgy, chemical manufacturers and other industries widely on the application. Ceramic valve with great social and economic benefits:

1. New ceramic structure using high-tech materials and vulnerable parts of the valve sealing components, valve products increased wear resistance, corrosion protection and sealing, greatly extended the life of the valve.

2. The use of ceramic valve can replace a large number of lower valve repair, improve equipment operation supporting system security, stability, reduce labor intensity, saving equipment repair costs.3. Ceramic valves can increase the tightness of industrial piping systems, while able to prevent disclosure of the maximum of environmental protection will play a positive role in pushing forward.4. Wide range of manufacturers of ceramic raw materials, low cost of aluminum, carbon, silicon and other common factors can not create superior performance ceramic materials, can save a lot of metal materials and scarce mineral resources.

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, high corrosion, high temperature, high pressure and other adverse conditions, but also demonstrated its superior performance. It can meet the high wear and tear, the use of highly corrosive environment, in particular outstanding feature is the long service life, its cost performance is far better than other similar metal valve. With the continuous development of science and technology and progress of, ceramic materials from the formulation, molding, machining and assembly process and other aspects of the technology become more mature and complete, its outstanding performance ceramic valve increasingly recognized by the industry. Using the successful experience of manufacturing ceramic valves can also be applied to a wider range of engineering fields.
