Abstract

Седло (10) шарового клапана для создания временного уплотнения пробки (40) содержит, по существу, цилиндрический корпус (30), имеющий первый объем и образующий посадочную поверхность (34). Когда пробка с созданием уплотнения взаимодействует с посадочной поверхностью, создается перепад давлений на уровне седла клапана. Корпус выполнен из упругого материала, который сжимается от первого объема ко второму меньшему объему за счет силы, прилагаемой пробкой, для образования зазора, который больше, чем закупоривающий размер пробки, что допускает прохождение пробки по потоку. После прохождения пробки корпус возвращается к его первому объему.
