Регулятор давления жидкости или газа компактной конструкции содержит усовершенствованный клапанно-диафрагменный узел, расположенный между проточной частью корпуса и второй его покрывающей частью. Проточная часть корпуса содержит входной и выходной каналы и полость клапана с установленной по центру вставкой клапана, имеющей отверстие для протекания регулируемой жидкости или газа. Установленная на проточной части корпуса его покрывающая часть охватывает диафрагму с клапанно-диафрагменным узлом и содержит регулируемую цилиндрическую пружину, прижимающую указанный узел. Клапанно-диафрагменный узел содержит выполненную в форме кольца диафрагму, установленную между расположенным по центру диафрагмы круглым элементом и зажимной пластиной ограничения давления, выполненной в форме кольца. Круглый элемент имеет центральную выемку, расположенную над вставкой клапана, в котором установлен подпружиненный самоустанавливающийся шаровой клапан с плоской поверхностью, примыкающей к вставке клапана. Благодаря выпуклости, выполненной в диафрагме, обеспечивается лучшая согласованность ее полезной площади сечения с ходом клапана при работе регулятора, улучшается регулировка давления и уменьшается растяжение диафрагмы, что предотвращает разрывы или нежелательный гистерезис.The pressure regulator for a liquid or gas of a compact design contains an improved valve-diaphragm unit located between the flow-through part of the body and its second covering part. The flow-through part of the housing contains inlet and outlet channels and a valve cavity with a valve insert installed centrally and having an opening for the flow of the regulated fluid or gas. Installed on the flow part of the body, its covering part covers the diaphragm with the valve-diaphragm assembly and contains an adjustable cylindrical spring which presses the indicated assembly. The valve-diaphragm assembly contains a ring-shaped diaphragm installed between a circular element located in the center of the diaphragm and a pressure limiting clamp plate made in the form of a ring. The circular element has a central recess located above the valve insert, in which a spring-loaded self-aligning ball valve is installed with a flat surface adjacent to the valve insert. Due to the convexity made in the diaphragm, it provides better consistency of its useful cross-sectional area with the valve stroke when the regulator is in operation, pressure regulation is improved and the diaphragm stretch is reduced, which prevents breaks or unwanted hysteresis.
