Abstract

The article discusses the dependence of the parameters of the safety valve on the geometry of the flow part. Direct-action single-stage safety valve is selected for the study. The influence of its case diameter on the hydraulic resistance coefficient was researched. A computational experiment was conducted using the Ansys Fluent software package. As a result, it is found that when the ratio of the plate diameter to the saddle diameter is 1.3 then a decrease of the body diameter to a value less than two diameters of the saddle is resulting in a significant increase of the coefficient of hydraulic resistance
