1. The thickness of the valve shell 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-section structure of the shell is designed, the body is sturdy and the appearance is beautiful. 2. The chemical elements of the valve stem material meet the requirements of the national standard, finely ground, 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. 3. Precise grinding technology and advanced machinery and equipment manufacturing and production. The valve structure is simple, the flow channel is smooth, and the medium flow resistance is small. The hard-sealed ceramic internal parts are composed of six scientific and reasonable designs. The valve ball and valve seat are contacted and processed, so that the inner R and outer R of the ball and the seat are closely combined. The ball has high precision, good surface quality, and light torque of the whole valve. , The resistance is small, and the sealing performance reaches zero leakage. 4. Built-in buffer compensation elastic gasket to ensure stable and good sealing. And in the medium containing impurities, it is not easy to get stuck and cause the ball to break. 5. The fully lined hard sealing surface contact ceramic ball valve all contact with the medium is made of structural ceramic material, its chemical stability plus extremely high hardness (hardness HRA88 or more, second only to diamond). Therefore, ceramics have high compressive strength, high wear resistance, excellent oxidation and corrosion resistance, high temperature resistance, and good thermal insulation properties. Application fields of wear-resistant and corrosion-resistant ceramic valves: thermal power plants, steel, petroleum, chemical, paper, biological engineering, and other industries. It is suitable for conveying boiler steam, lime slurry, seawater containing particles, high hardness particles, corrosive media containing soft particles, powder, flue gas desulfurization, ash discharge, slag discharge, and water supply treatment. The material can be changed according to the purpose, and it can be used in different temperatures and media. The only national standard for ceramic valves: JB/T10529-2005 Design and manufacture standards: API6D-2008, API608-2002 Structure length standard: GB/T 12221-2005, ANSI B16.10 Connection flange standard: GB/T 9113, ANSI B16. 5 Pressure and temperature grade: GB/T 12224-2005, ASMEB16.34-2004 Test and inspection standard: GB/T 13927-2008API 598 Ceramic valve product classification: ceramic ball valve, ceramic gate valve, ceramic butterfly valve, ceramic check valve, ceramic slag discharge Valve, ceramic rotary valve, ceramic discharge valve, ceramic dome valve, ceramic regulating valve, ceramic globe valve, ceramic dry ash valve, ceramic pneumatic thin knife gate valve, ceramic double-phase flow gate valve, ceramic knife gate valve, ceramic single gate valve Valve, wear-resistant check valve, pneumatic wear-resistant ball-topped globe valve, cast stone wear-resistant ball type three-way reversing valve, cast stone wear-resistant ball valve, etc.
