标准摘要
[中文适用范围]: 标准本节中提出的方程基于牛顿不可压缩流体的伯努利方程。它们不适合在遇到非牛顿流体@流体混合物@浆料@或液固输送系统时使用。 [外文原描述]: Deals with a general sizing equation for incompressible fluid flow under installed conditions. Factors are introduced which permit accurate sizing when choked conditions exist due to either cavitation or flashing. Procedures and factors are incorporated to handle installations where the valve is installed between fittings such as reducers, expanders, etc. A Reynolds number factor allows for applications where non-turbulent flow conditions exist caused by low differential pressure and/or high viscosity fluids. Numerical constants are presented permitting the use of three recognized flow coefficients: Av, Kv, and Cv.
