Nuclear
Nuclear power valve discussion Nuclear power valve refers to the valve used in nuclear island N1, conventional island CI and power plant auxiliary facilities BOP system in nuclear power plant. From the safety level, it is divided into nuclear safety level I, II, III and non-nuclear level. Among them, nuclear safety level I has the highest requirements. Nuclear power valves are the most widely used medium transmission control equipment in nuclear power plants, and are an indispensable and important part of the safe operation of nuclear power plants. 1. The level of domestic nuclear power valves At present, 19 domestic enterprises have obtained the design and production qualification license of civil nuclear pressure equipment issued by the National Nuclear Safety Administration, and can design and produce nuclear-grade valves. its design,

Power station valve
Power
Brief introduction of power station valve "Power station valve" is also called special valve for power station. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, the power station valve is characterized by high temperature and high pressure, and a unique self-sealing design. The higher the pressure, the more reliable the sealing. Due to the special performance and technical characteristics and the special working conditions, the product also has characteristics that cannot be replaced by other products. Main Design Specifications for Power Station Valves Design and Manufacture GB/T12234ASMEB16.34 Structure Length JB/T3595 Interface Connection Dimensions JB/T3595

Corrosion Resistant Valve
Corrosion
1. Sulfuric acid medium, as one of the strong corrosive medium, sulfuric acid is an important industrial raw material with a wide range of uses. Different concentrations and temperatures of sulfuric acid have great differences in the corrosion of materials. For concentrated sulfuric acid with a concentration of more than 80% and a temperature of less than 80 °C, carbon steel and cast iron have better corrosion resistance, but it is not suitable for high-speed flowing sulfuric acid. Materials that are not suitable for pump valves, such as ordinary stainless steel such as 3040Cr18Ni9, 3160Cr18Ni12Mo2Ti, have limited use in sulfuric acid media. Therefore, the pumps and valves for conveying sulfuric acid are usually made of high-silicon cast iron, which is difficult to cast and process, and high-alloy stainless steel.
