Customized valve ball seat and valve seat cemented carbide ball valve seat ring
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 balls, ball seats, which are 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 an absolute pressure below 0.36 kg N/cm, and the pressure value does not change within 10 seconds.)
Carbide seat features:
1. Alloy Seat and Cemented Carbide Ball Matching Use
2. Alloy seat has excellent sealing and wear resistance
3. Smooth and smooth inclined surface of the alloy seat
1. High strength, high wear resistance, high precision, and good temperature and corrosion resistance.
2. Mainly used for the sealing of valves of oil pumps in the petroleum industry, containing wells, viscous oil wells, sea oil wells, and high-pressure sulfur-resistant oil wells etc.
3. Balls and seats are used with compatible cemented carbide valve seats.
4. The finished surface, tolerance standards have reached the standards of the machine industry: G5, G10, G16, G40 and G100.
5. Precision-machined cemented carbide balls of other grades and specifications are also available based on customers` demands.
6. Compatible high-precision valve seats can also be made.
Other types of bars may be offered according to customers' requirements.
