摘要
水电站高压力大型进水球阀的基础结构一般采用球阀底座与球阀基础板能够相对滑动的设计.就不同摩擦系数下,由于温度变化造成的挤压力对球阀支腿和混凝土支墩的影响进行了计算分析;对球阀底座与球阀基础间不同滑动副结构进行了对比分析.
Abstract
The foundation structure of large inlet ball valves for hydropower stations with high pressure generally adopts the design that the base of the ball valve and the base plate of the ball valve can slide relative to each other.Under different friction coefficients,the influence of extrusion pressure due to temperature change on ball valve legs and concrete piers is calculated and analysed;different sliding sub-structures between ball valve base and ball valve foundation are compared and analysed.
