Abstract

Перепускной клапан содержит корпус (1) с газовпускным отверстием и газовыпускным отверстием для выпуска газа, у которого установлен обратный клапан (4). Обратный клапан (4) содержит корпус (41), вентиляционную пластину (42) и первую уплотнительную прокладку (43). В корпусе (41) обратного клапана проходит первый газовый канал (411) для прохождения газа. В вентиляционной пластине (42) выполнены вентиляционные отверстия (421), сообщающиеся с газовыпускным отверстием. Между вентиляционной пластиной (42) и корпусом (41) обратного клапана расположена первая уплотнительная прокладка (43), с помощью которой первый газовый канал (411) и вентиляционные отверстия (421) выборочно сообщаются друг с другом. Обратный клапан (4) расположен в газовыпускном отверстии перепускного клапана и обеспечивает однонаправленное протекание газа, благодаря чему достигается решение проблемы изменения заданной концентрации анестезирующего газа из-за обратного газового потока. Кроме того, предлагаемый перепускной клапан имеет более простую конструкцию и лучшую газонепроницаемость.
