Tungsten Carbide Valve Balls Introduction
The tungsten carbide valve balls or tungsten carbide ball valves is evolved from the traditional plug valve. Its opening and closing part is a sphere, and the purpose of opening and closing is realized by the sphere around the axis of the valve stem.
High-precision tungsten carbide balls are widely used in oil drilling and deep-sea drilling pump valve balls and ball seats, which are also one of the most critical components in oil pumps. Due to the harsh working environment and conditions in the petroleum drilling industry, sandy wells, heavy oil wells, and high-pressure oil-repellent wells usually contain water, various gases, waxes, sand and other highly corrosive substances.The oil well pump needs to extract oil from several hundred or even thousands of meters of stratum, which requires its valve ball and valve seat to have good sealing performance, wear resistance and corrosion resistance (the valve ball and valve seat are combined to vacuum to absolute If the pressure is below 0.36kgN/cm, the absolute pressure value will not change within 10s).
Applicable occasions of several common tungsten carbide valve balls:
1. It is suitable for the piping system with two-position adjustment, high sealing performance requirements, rapid opening and closing (1/4 turn opening and closing), large pressure difference, small operating torque, small flow resistance, cavitation or vaporization phenomenon Use cemented carbide ball valve;
2. In the pipeline with a certain corrosive medium;
3. In low-temperature cryogenic devices or high-temperature and high-pressure pipeline systems;
4. Full-diameter welded tungsten carbide valve balls can be used in oil pipelines and gas pipelines that need to be buried underground;
5. The specially designed V-shaped opening structure tungsten carbide valve ball can also have a certain adjustment function.
