The national standard carbon steel corrosion-resistant flange gate valve is a valve produced according to Chinese national standards, with corrosion-resistant characteristics and suitable for various media. Here are some key features:
1. * * Design Standard * *: Following the national standard GB/T 12234-2019, it is suitable for steel gate valves with screw connected valve covers used in the petroleum and natural gas industries.
2. * * Material * *: The valve body material is usually carbon steel, such as WCB (carbon steel), which is suitable for general industrial applications. The sealing surface can be made of stainless steel, Cr alloy or hard alloy to improve corrosion resistance and wear resistance.
3. * * Structural Features * *: Adopting a wedge-shaped elastic gate structure, with rolling bearings installed on the medium and large diameters, making opening and closing easy. The valve stem and upper sealing valve seat are made of materials with anti-corrosion properties, such as stainless steel or heat-resistant alloy steel, and undergo appropriate heat treatment.
4. Corrosion resistance: By selecting appropriate materials and heat treatment methods, as well as using corrosion-resistant sealing materials, the corrosion resistance of the valve can be improved.
5. * * Application scope * *: Suitable for pipelines with nominal pressure PN1.0~16.0MPa, working temperature -29~425 ℃ (carbon steel) and -40~200 ℃ (stainless steel), used to cut off or connect media in pipelines. By selecting different materials, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and urea.
6. * * Drive mode * *: The drive modes include manual, bevel gear transmission, and electric, which are convenient for remote control and meet different user needs.
7. * * Testing and Inspection * *: Conduct pressure testing, sealing testing, and upper sealing testing in accordance with national standards to ensure the reliability and safety of the valve.
8. * * Marking and Packaging * *: There are clear markings on the valve body and cover, including product model, standard number, nominal pressure, and other information. Valves are protected and packaged before leaving the factory for easy storage and transportation.
National standard carbon steel corrosion-resistant flange gate valves are widely used in industries such as chemical, petroleum, natural gas, and water treatment due to their corrosion resistance, reliable sealing, and excellent performance
