The Turbine Stainless Steel Fixed Ball Valve is a high-performance fluid control device with numerous advantages and a wide range of application scenarios. Below is a detailed introduction to the Turbine Stainless Steel Fixed Ball Valve:
Definition and Structure
A Turbine Stainless Steel Fixed Ball Valve is a valve that uses a spherical body with a circular passage as the shut-off element. The sphere is fixed within the valve body and does not move with the medium pressure. Its structure mainly includes the valve body, sphere, valve stem, and sealing ring, etc.
Operating Principle
When the valve stem rotates 90 degrees, the channel on the ball aligns or misaligns with the channel of the valve body, thereby opening or closing the fluid flow. The fixed ball valve supports the ball with bearings to reduce friction, making operation effortless, and it features bidirectional sealing, with no flow direction restriction during installation.
Key Features
Easier Operation: The sphere is supported by upper and lower bearings, reducing friction for easier operation.
Reliable Sealing Performance: Equipped with PTFE sealing rings embedded in the stainless steel valve seat, the metal valve seat end features a spring to ensure sufficient pre-tension for the sealing ring, maintaining a good seal even when the sealing surface wears.
Wide Application Range: Suitable for various corrosive and non-corrosive mediums, and for high-pressure and large-diameter applications.
Fire-resistant structure: Equipped with a fire-sealing ring to prevent the seal from burning due to sudden heat or fire.
Auto-Relief Function: When the medium pressure rises abnormally, the valve seat retracts and detaches from the ball, achieving the effect of automatic pressure relief. After pressure is released, the valve seat automatically resets.
Application Scenario
Turbine stainless steel fixed ball valves are widely used in the fields of oil, petrochemical, power, environmental protection, water conservancy, heating, water supply and drainage, industry, and machinery. Especially in high-pressure and large-diameter applications such as long-distance pipelines and general industrial pipelines, fixed ball valves perform exceptionally well.
