The analysis of working medium flow through flow cavity elements of pneumatic-hydraulic systems
The article discusses the issues of modeling the flow of working medium in the working cavity of ball valves with various types of designs of locking elements: with turned and stamped ball. Special attention is paid to obtaining the characteristics of hydraulic resistance depending on the angle of...

| Summary: | The article discusses the issues of modeling the flow of working medium in the working cavity of ball
valves with various types of designs of locking elements: with turned and stamped ball. Special attention
is paid to obtaining the characteristics of hydraulic resistance depending on the angle of rotation of
the regulating element. Mathematical modeling of the gas flow process in the considered types of ball
valves is carried out, pressures and velocities in the working cavity of ball valves are determined. The
analysis of the obtained data made it possible to estimate the error of the computational method based
on a comparison with the published experimental data. Recommendations on the use of ball valves with
turned and extruded ball are given |
