INDUSTRIAL PROCESS CONTROL VALVES - FLOW CAPACITY - METHODS OF TEST
出版：British Standards Institution
專家解讀視頻
Covers industrial-process control valves and gives flow capacity test procedures for evaluating variables used in the equations given in I E C Publications 534-2: Industrial-process Control Valves, Part 2: Flow Capacity, Section One - Sizing Equations for Incompressible Fluid Flow under Installed Conditions, and 534-2-2: Part 2: Flow Capacity, Section Two - Sizing Equations for Compressible Fluid Flow under Installed Conditions. The variables covered are: flow coefficient, liquid pressure recovery factor, combined liquid pressure recovery factor and piping geometry factor, piping geometry factor and pressure differential ratio factors. Comments on determination of liquid critical pressure ratio factor and Reynolds number are given. BS AMD 7818 RENUMBERS THIS STANDARD TO BS EN 60534 PT2-3
