Corrosion Resistance Carbide Valve Bearing Seat And Ball

The cemented carbide ball or cemented carbide ball valve 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. It is widely used in oil drilling and deep-sea drilling pump valve ball and ball seat, which is also one of the key components in the pump. Due to the harsh working environment and conditions in the petroleum drilling industry, sand wells, heavy oil wells, and high-pressure oil-repellent wells usually contain water, various gases, wax, sand and other highly corrosive substances, which are required for oil wells. To extract oil from several hundred or even thousands of meters of stratum, this requires the valve ball and valve seat to have good sealing performance, wear resistance and corrosion resistance (the valve ball and valve seat are matched and vacuumed to an absolute pressure of 0.36kgN /cm, the absolute pressure value does not change within 10s).

Cemented carbide valve ball or cemented carbide ball valve is evolved from the traditional plug valve. Its opening and closing parts are a ball, and the purpose of opening and closing is realized by the ball around the axis of the valve rod. The hard alloy valve seat is used in various specifications and configurations, and can be used under wearing, corrosive and corrosive conditions. Alloy valve seat is matched with alloy ball.
