Claims (3)

1. Устройство для перекрытия трубопровода, содержащее цилиндрический корпус с фланцем, предназначенный для встраивания в трубопровод, размещенный коаксиально внутри корпуса и закрепленный на нем цилиндрический каркас, на котором установлена тороидальная оболочка, деформируемая под действием внутреннего давления сжатого газа с возможностью перекрытия кольцевого промежутка между каркасом и корпусом.1. A device for shutting off a pipeline, comprising a cylindrical body with a flange, designed to be embedded in a pipe placed coaxially inside the body and mounted on it with a cylindrical frame on which a toroidal shell is installed, which is deformed under the action of internal pressure of the compressed gas with the possibility of overlapping the annular gap between the frame and body. 2. Устройство по п.1, отличающееся тем, что корпус выполнен с каналом в стенке, соединенным с полостью оболочки для подачи в нее среды под давлением и сброса давления.2. The device according to claim 1, characterized in that the housing is made with a channel in the wall connected to the cavity of the shell for supplying a pressure medium therein and pressure relief. 3. Устройство по п.1 или 2, отличающееся тем, что указанная оболочка выполнена резинокордной.3. The device according to claim 1 or 2, characterized in that said shell is made of rubber cord.
