Abstract

Дросселирующее устройство с пусковым клапаном (4) включает корпус (24), в котором выполнен цилиндрический отсек (25) корпуса и установлен переключающий элемент (26) с возможностью изменения положения между положением выпуска и положением передачи. В положении выпуска переключающий элемент (26) образует выпускной канал (34), который соединяет входной канал (33) с выпускным отверстием (35). В положении передачи переключающий элемент (26) образует пропускной канал (36), который соединяет входной канал (33) с передающим каналом (37). Дроссельный элемент (38) установлен в пропускном канале (36) таким образом, чтобы можно было изменять его положение относительно переключающего элемента (26). За счет этого обеспечено дросселирование в необходимом режиме потока расплава (23), проходящего через пропускной канал (36). Дросселирующее устройство с пусковым клапаном (4) выполнено в виде простой, компактной и надежной конструкции. Эксплуатация дросселирующего устройства с пусковым клапаном (4) и связанного с ним шнекового экструдера (3) отличается простотой и энергоэффективностью.
