GB standard lift check valve is a common type of valve, mainly used to prevent medium backflow, protect pipelines and equipment. Here are some introductions to lift check valves based on national standards:
1. * * Design and Manufacturing * *: The lift check valve is designed, manufactured, and inspected in accordance with the national standard GB/T 12235 to ensure reliable sealing and excellent performance.
2. Sealing surface material: The sealing surface of the valve disc and seat is usually made of iron-based alloy or Stellite cobalt based hard alloy by welding, which has the properties of wear resistance, high temperature resistance, corrosion resistance, and abrasion resistance, thereby extending the service life of the valve.
3. * * Flange standards * *: Various piping flange standards and flange sealing surface types can be used to meet different engineering and user requirements.
4. * * Valve Body Material * *: The valve body material variety is complete, and the gasket can be reasonably selected according to actual working conditions or user requirements, suitable for various pressure, temperature, and medium working conditions.
5. * * Pressure rating * *: The nominal pressure PN range is from 1.6 to 16MPa, suitable for different working pressure environments.
6. * * Test pressure * *: The shell strength test pressure is 1.5 times the nominal pressure at room temperature, and the high-pressure sealing test pressure is 1.1 times the nominal pressure at room temperature.
7. * * Working Temperature * *: Suitable for different working temperature ranges, depending on the material selection and design.
8. * * Installation precautions * *: During installation, special attention should be paid to the direction of medium flow to ensure that the normal flow direction of the medium is consistent with the direction indicated by the arrow on the valve body.
9. * * Standard Status * *: The current national standards are GB/T 12233-2006 and GB/T 12235-2007, which specify the design, manufacturing, inspection, and testing requirements for check valves.
10. * * Other features * *: The lift check valve has the characteristics of compact structure, small volume, light weight, sensitive action, reliable sealing, and easy installation, making it suitable for situations with limited installation space.
