Description
( УСТРОЙСТВО дл ПЕРЕКРЫТИЯ ТРУБОПРОВОДА(DEVICE FOR CLOSING A PIPELINE
. 1. one
- . .- л.Изобретение относитс к запорным устройствам трубопроводов с жидкост ми , преимущественно дл перекрыти трубопроводов различного сечени р системах с жидко-металлическим теплоносителем . -. .- l.The invention relates to shut-off devices of pipelines with liquids, mainly for shutting off pipelines of various cross sections and systems with a liquid-metal coolant.
Известно устройство дл перекрыти трубопровода, состо щее из корпуса с перекрывным элементом, образованным замораживанием потока среды, проход щего через корпус 1 1.A device for blocking a pipeline is known, consisting of a housing with a ceiling element formed by freezing the flow of the medium passing through the housing 1 1.
Однако в известно устройстве теплоноситель , замороженный в трубе, может быть выбит ударной волной, к|)Оме того, затруднительно заморозить теплоноситель в трубах большого диаметра . Быстродействие таких устройств невелико.However, in a known device, a coolant frozen in a pipe can be knocked out by a shock wave, because it is difficult to freeze the coolant in large-diameter pipes. The performance of such devices is small.
Цель изобретени - повышение надежности работы и быстродействи .The purpose of the invention is to improve the reliability and speed.
Поставленна цель достигаетс тем, что перекрывной элемент выполнен вThe goal is achieved by the fact that the overlapping element is made in
