Эксцентриковые дисковые затворы: Обзор
Eccentric butterfly valves are quarter-turn valves that utilize a disc with an offset shaft to control fluid flow. This design ensures that the disc is fully disengaged from the flow path when the valve is open, reducing turbulence and pressure drop. Here are some key features of high-performance eccentric butterfly valves:
а) Sealing Capability: Eccentric butterfly valves provide excellent sealing performance due to the eccentric disc design. The disc is positioned off-center, allowing a bubble-tight seal against the valve seat when closed, минимизация утечки.
б) Low Torque Requirement: The eccentric disc design reduces the torque required to operate the valve. This results in easier and more efficient valve actuation, reducing operational costs and enhancing system performance.
с) Pressure Drop Reduction: High-performance eccentric butterfly valves are designed to minimize pressure drop when fully open, ensuring efficient flow with minimal energy loss.
