Baigang valve group brand manufacturing -Ceramic Valve

Ceramic Valve introduce

The application of ceramic materials in industrial valves is a bold and beneficial innovation.Ceramic material deformation is very small, has a much higher bond strength than metal, under normal circumstances, the crystal ion radius of ceramic material is small, and the ion price is high, the coordination number is large, these properties determine the tensile strength, compressive strength, elastic modulus, hardness of ceramic materials are very high.Ceramic itself, however, "brittle" and difficult processing limits its scope of application of recent decades, due to the martensitic phase transformation toughening technology, composite material science and technology development and progress of the concept of nanometer ceramics made of pottery and porcelain "brittle" has been greatly improved, the toughness and strength has been greatly improved, expanding application range.

Ceramic Valve structural features

1, the valve shell thickness exceeds the national standard GB, JB and ANSI standard data requirements, the main material chemical elements and mechanical properties meet the national standard requirements.Shell three - section structure design, solid shape, beautiful appearance.
2, the valve stem material chemical elements meet the requirements of the national standards, fine grinding, the surface by corrosion resistance nitriding or quenching treatment, ensure that the valve stem has good mechanical properties and corrosion resistance.
3, Built-in buffer compensation elastic washer, to ensure the stability of good tightness.And in the medium containing impurities, it is not easy to get stuck causing the ball to break.
4, all lining hard sealing surface contact ceramic ball valve all contact with the medium is structural ceramic material, its chemical stability plus high hardness (hardness HRA88 above, second only to the characteristics of metalstone).Therefore, ceramics have high compressive strength, high wear resistance, excellent oxidation and corrosion resistance, high temperature resistance and good heat insulation properties.
5, with accurate grinding technology and advanced mechanical equipment manufacturing production.The valve structure is simple, the flow channel is smooth, the medium flow resistance is small.Hard sealing ceramic inner parts, composed of six scientific and reasonable design, valve ball, valve seat surface contact processing, so that the ball and seat R and R closely combined, ball round high precision, good surface quality, so that the whole valve torque light, small resistance, sealing to zero leakage.
