Abstract

Изобретение относитс  к вентил ции и служит дл  удалени  вредностей от перемещающегос  источника вредностей. Устройство дл  удалени  вредностей от источника содержит выт жной воздуховод, установленный в нем патрубок 3 с захватом дл  соединени  с трубой 4 источника. Патрубок 3 снабжен запорным элементом, а захват выполнен в виде надувной кольцевой камеры 5, образованной эластичной негорючей оболочкой, установленной на внутренней поверхности патрубка 3. Запорный элемент выполнен в виде поворотной заслонки 7 со штоком 8, взаимодействующим с трубой 4. 3 ил.The invention relates to ventilation and serves to remove hazards from a moving source of hazards. The device for removing hazardous substances from the source contains an exhaust duct, a branch pipe 3 installed therein with a grip for connection to the source pipe 4. The pipe 3 is provided with a locking element, and the grip is made in the form of an inflatable annular chamber 5 formed by an elastic non-combustible shell installed on the inner surface of the pipe 3. The locking element is made in the form of a rotary valve 7 with the rod 8 interacting with the pipe 4. 3 Il.
