Fully lined hard-sealed ceramic valve features:
First, the thickness of the valve casing exceeds the standard data requirements of national standards GB, JB and American Standard ANSI, and the chemical elements and mechanical properties of the main material meet the national standard requirements. The three-segment structure design of the shell has a solid shape and a beautiful appearance.
2. The chemical elements of the valve stem material meet the requirements of national standards. They are finely polished and the surface is treated with anti-corrosion, nitriding or quenching and tempering to ensure that the valve stem has good mechanical properties and corrosion resistance.
Third, built-in buffer compensation elastic gasket to ensure stable and good sealing. And in the medium containing impurities, it is not easy to jam and cause the ball to break.
Fourth, all lined hard sealing surface contact ceramic ball valve is in contact with the medium are structural ceramic materials, its chemical stability plus extremely high hardness (hardness HRA88 or higher, second only to diamond). Therefore, ceramics have high compressive strength, high abrasion resistance, excellent oxidation and corrosion resistance, high temperature resistance, and good thermal insulation properties.
5. Manufacture with precise grinding technology (introduced in Taiwan) and advanced machinery and equipment. The structure of the valve is simple, the flow passage is smooth, and the resistance of the medium flow is small. The hard-sealed ceramic inner parts are composed of six scientific and reasonable designs. The ball and seat surfaces of the valve are processed in contact, which makes the ball and the inner R and outer R tightly combined. , Low resistance, zero leak tightness.
Application areas: thermal power plants, steel, petroleum, chemical, papermaking, bioengineering, and other industries. It is suitable for boiler steam, lime slurry, seawater containing particles, high hardness particles, soft particles and corrosive media, powder, flue gas desulfurization, ash, slag and water treatment. The material can be changed according to the purpose, and can be used in different temperatures and media.
