   <abstract xml:lang="ru">
    <p>В настоящей работе представлены результаты исследования основных характеристик процесса дросселирования жидкости в регулирующем осевом клапане с учетом зависимости моделируемого коэффициента гидравлического сопротивления от конструктивных и режимных параметров. В частности, выполнен расчет пропускной способности и пропускной характеристики сепаратора указанного клапана с позиций варьирования степени его открытия. Выявлены наиболее значимые факторы, влияющие на изменение данных показателей работы осевого клапана. Например, при максимальной степени открытия клапана увеличение диаметра дроссельных отверстий в 2 раза приводит к росту условной пропускной способности в 1.66 раза и пропускной характеристики в 1.19 раза. Показано, что в выбранных диапазонах изменения конструктивных параметров процесса дросселирования рабочей среды увеличение степени открытия клапана до 60% приводит к плавному росту пропускной характеристики до значений, не превышающих 0.3. Указанная нелинейная зависимость пропускной характеристики регулирующего осевого клапана создает предпосылки для выбора профилирования данного показателя. Практическое применение рассмотренных в настоящем исследовании вопросов нашло отражение при разработке инженерной методики расчета конструктивных параметров для соответствующего регулирующего клапана с реализацией процесса дросселирования потоков рабочей среды.</p>

    <p>This paper presents the results of a study of the main characteristics of the process of throttling a liquid in a control axial valve, taking into account the dependence of the modeled coefficient of hydraulic resistance on the design and operating parameters. In particular, the calculation of the throughput and throughput characteristics of the separator of the specified valve from the standpoint of varying the degree of its opening has been performed. The most significant factors influencing the change in these indicators of the axial valve operation are revealed. For example, at the maximum degree of valve opening, an increase in the diameter of the throttling holes by 2 times leads to an increase in the nominal throughput by 1.66 times and the throughput characteristic by 1.19 times. It is shown that in the selected ranges of changes in the design parameters of the throttling process of the working medium, an increase in the valve opening degree up to 60% leads to a smooth increase in the throughput characteristic to values not exceeding 0,3. The specified non-linear dependence of the flow characteristic of the control axial valve creates the prerequisites for choosing the profiling of this indicator. The practical application of the issues discussed in this study was reflected in the development of an engineering methodology for calculating design parameters for the corresponding control valve with the implementation of the process of throttling the flows of the working medium.</p>
