Application range and selection of ceramic ball valves
China is a country with an energy structure dominated by coal. Air pollution is a soot-type pollution. Dust, sulfur dioxide (SO2) and nitrogen oxides (NOX) are the main pollutants in China's atmosphere. In the industries of electric power, metal smelting, glass and glass fiber, chemical industry, etc., due to coal, mineral raw materials containing high sulfur, calcium fluoride, etc., the flue gas contains a large amount of harmful gases such as sulfur dioxide and HF. It causes serious pollution to the atmosphere and is an important cause of acid rain. Acid rain and sulfur dioxide pollution have caused serious economic losses in crops, forests and human health, and have become an important factor restricting Chinese economic and social development.
Ceramic ball valves are suitable for high temperature, strong corrosive, strong abrasive media such as blast furnace exhaust.
Advanced ceramic materials, with their high hardness, high strength, high wear resistance and good anti-corrosion performance, have been favored by developed countries since the Second World War. They competed in human and material resources to develop engineering ceramics. It was first used in military and aerospace industries, such as rocket tail nozzles, space shuttle insulation panels, armored vehicles, etc. Engineering ceramics, also known as structural ceramics, have fundamental differences in ordinary ceramics. Later, it gradually developed from ceramic engines and ceramic bearings to ceramic watches, ceramic scissors, and fruit knives. The development and application of advanced ceramic materials in China was included in China's "863" plan as early as the end of the 1970s. Due to the decoupling of applications, the development of structural ceramics in China began only in the early 1990s. Jintai Merrill Lynch keeps up with the international trend. In order to promote the application and development of new materials in China's ceramic industry, Jintai Merrill Lynch has developed high-performance ceramic ball valves with international advanced level. It has been used by many large enterprises at home and abroad, and its quality has reached the international leading level.
The ceramic ball valve solves the two problems of high corrosion and high solid content wear in the FGD working condition. Due to the high hardness, high strength, high wear resistance and good anti-corrosion performance of the advanced ceramic materials, the corrosion resistance, abrasion resistance and high temperature resistance of the valve can be greatly improved, and the service life of the valve is greatly prolonged, thereby extending the work cycle, improving work efficiency and saving maintenance costs. In the process of adjusting limestone slurry and gypsum slurry waste water, ceramic regulating valve is the most ideal valve at present, which has a very high promotion value.
