Beschreibung
Zusammenfassung:	FIELD: construction. ^ SUBSTANCE: invention refers to the sphere of construction and deals with design of doors to be installed within shelters and other defense facilities. The sealed door consists of a frame, a sealer, a push frame, hinges, door panels (the inner, the outer and the floating ones), vacuum string chambers. The vacuum string chambers are executed in the form of sylphons equipped with bearing flanges contacting the floating door panel. Inside the sylphons there are Belleville spring washers arranged, their larger diameter edges contacting the sylphons equipped with bearing flanges. The opposite edges of the spring washers contact the door inner panel. Along the door outer perimeter there is a cooling pipeline laid (in immediate proximity to the sealer) which is connected to the fire extinguishing system. The pipeline inlet is equipped with a solenoid-actuated valve. ^ EFFECT: door fire resistance enhancement. ^ 6 cl, 2 dwg
