The three-part connection forged steel fixed ball valve divides the body into three parts along the section perpendicular to the axis of the valve passage at the position of the two seats, the whole valve high pressure forged steel ball valve high pressure forged steel ball valve is symmetrical along the center axis of the stem it is mainly used in the pipeline to cut off, distribute and change the direction of medium flow. Its large pivot structure ensures accurate ball center position under high pressure and ensures good valve operating performance; standard seats are spring-loaded, pushing the seat toward the ball, the utility model has the advantages of Good Inlet and outlet two-way sealing performance, using the self-provided discharge valve, the cavity of the valve body can be discharged outwards, using the blow-out protective structure of the pivot to effectively prevent leakage, and using the bearing with low friction coefficient, minimize torque to facilitate valve opening and closing, stem effective contact with the valve body, making anti-static grounding device superior performance. The utility model has the advantages of excellent performance, high reliability, wide use, reasonable price, etc. . Applicable to: Chemical, petroleum, natural gas, metallurgy, and other industries and containing hydrogen sulfide medium, impurities, serious corrosion of long-distance natural gas pipelines.
