Cemented Balls and Valve Seats Valve or Cemented Balls and Valve Seats Valve is evolved from the traditional cock valve. Its opening and closing parts are a sphere. The purpose of opening and closing is achieved by the sphere around the axis of the valve stem. Widely used in oil drilling, deep-sea drilling pump valve ball, ball seat, which is also one of the key components of the pump. Because of the harsh working environment and conditions in the oil drilling industry, water, various gases, waxes, sand and other highly corrosive substances are usually contained in sand-bearing wells, heavy oil wells and high-pressure anti-dredging wells. Oil pumps need to extract oil from hundreds or even thousands of meters of formation, which requires the valve balls and seats to have good sealing, wear resistance and corrosion resistance. (After the ball and seat cooperate, the vacuum is pumped to the absolute pressure below 0.36 kg N/cm, and the pressure value does not change within 10 seconds).
