The working principle of forged steel ball valve is to turn the stem to make the valve unblocked or blocked. It can make full-diameter ball valve, 90 degree angle, ball valve switch light, small size, large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and sphere are often in closed state, not easy to be eroded by medium, and it has been widely used in various industries. Forged steel ball valves: low pressure forged steel ball valves, high pressure forged steel ball valves.
The three-body connection forged steel fixed ball valve divides the body into three parts along the cross section perpendicular to the axis of the valve passage at the two seat positions. The whole high-pressure forged steel ball valve is symmetrical along the central axis of the valve stem. It is mainly used to cut off, distribute and change the direction of medium flow in the pipeline. Its large pivot structure ensures accurate ball center position under high pressure and good operation performance of the valve; the standard valve seat adopts spring structure to push the valve seat to the ball, which ensures good two-way sealing performance for inlet and outlet; the valve body cavity can be discharged outward by using the self-contained discharge valve; the pivot adopts blowout-proof protection. The structure effectively prevents leakage; the bearing with low friction coefficient reduces the torque to *** small, facilitates the opening and closing of the valve; the effective contact between the valve stem and the valve body makes the anti-static grounding device superior in performance, etc. It has the advantages of excellent performance, high reliability, wide use and reasonable price. Applicable to: chemical, petroleum, natural gas, metallurgy, and other industries and hydrogen sulfide containing medium, impurities, serious corrosion of natural gas pipelines.
1. The valve seat adopts spring structure, pushing the valve seat toward the sphere to ensure good low pressure sealing performance.
2. Before fixing the ball valve, the back seat of the valve can be sealed, that is, the so-called two-way sealing characteristics. By using the self-contained discharge valve, the body cavity can be discharged outward.
3. Q347F forged steel fixed ball valve pivot adopts blowout-proof protection structure, low friction coefficient bearings, etc. It has excellent performance, high reliability and wide application.
