High pressure forged steel ball valve, high-pressure ball valve, high-pressure flange ball valve, stainless steel high-pressure ball valve and forged steel fixed ball valve are three-part connected forged steel fixed ball valves. The valve body is divided into three parts along the section perpendicular to the axis of the valve channel at the two valve seats. The whole valve is symmetrical left and right along the central axis of the valve stem. It is mainly used to cut off, distribute and change the direction of medium flow on the pipeline. Its large pivot structure ensures the accurate center position of the ball under high pressure and ensures the good operation performance of the valve; The standard valve seat adopts spring structure, which pushes the valve seat to the ball, ensuring good import and export two-way sealing performance; Using the built-in discharge valve, the middle cavity of the valve body can be discharged outward; The pivot adopts anti blow out protection structure to effectively prevent leakage; The bearing with low friction coefficient reduces the torque to small, which is convenient for the opening and closing of the valve; The effective contact between the valve stem and the valve body makes the performance of the anti-static grounding device superior. It has the advantages of excellent performance, high reliability, wide application and reasonable price. The ball valve is suitable for chemical industry, petroleum, natural gas, gas, liquefied petroleum gas, metallurgy, and other industries, as well as long-distance natural gas transmission pipelines containing hydrogen sulfide medium, many impurities and serious corrosion.
