Super Hard Tungsten Carbide Ball Contact To Valve Seat For Opening And Closing
High-precision tungsten-cobalt carbide balls are widely used in oil drilling, deep-sea drilling pumping ball, ball seat, which is also the most critical component of the pump. Due to the harsh working environment and conditions in the oil drilling industry, it is usually contained in sand wells, heavy oil wells and high-pressure anti-sloping wells with some corrosive substances such as water, various gases, waxes, sands, etc. The oil is extracted from several hundred or even thousands of layers, which requires the valve ball and the valve seat to have good sealing, wear resistance and corrosion resistance (the valve ball and the valve seat are combined and then vacuumed to an absolute pressure of 0.36kgN). Below /cm, the absolute pressure value does not change within 10s.
Specification:
The common grades of tungsten carbide balls are YG3, YG6, YG6X, YG8, YG8X,YG13. The most common are YG6 and YG8.

Reference Illustrate:
The main advantages of cemented carbide ball valves can be divided into the following aspects:
Applicable occasions for several common carbide ball valves:
1. In the double position adjustment, it is suitable for the sealing performance, high opening and closing (1/4 turn opening and closing), large pressure difference, small operating torque, small flow resistance, cavitation or vaporization. Use a carbide ball valve;
2. In a pipeline with a corrosive medium;
3. In a low temperature cryogenic device or a high temperature and high pressure pipeline system;
4. Full-diameter welded carbide ball valve can be used in oil pipelines and gas pipelines to be buried underground;
5. Specially designed V-shaped open structure carbide ball valve can also have certain adjustment functions.
