Description
(54) УСТРОЙСТВО ДЛЯ ПЕРЕКРЫТИЯ ТРУБОПРОВОДА(54) DEVICE FOR CLOSING A PIPELINE
1one
Изобретение относитс к устройствам перекрыти трубопроводов с жидкост ми и может примен тьс дл перекрыти трубопроводов различного сечени в циркул ционных контурах быстрых реакторных установок с жидкометаллическим теплоносителем, например натрием.The invention relates to devices for shutting off pipelines with liquids and can be used to shut off pipelines of various cross sections in the circulation circuits of fast reactor plants with liquid metal coolant, for example sodium.
Известно устройство дл перекрыти трубопровода посредством замораживани проход щей по нему среды, в качестве которого использован кожухотрубный холодильник, содержащий корпус с патрубками, внутри которого расположен трубный пучок 1..A device is known for shutting off a pipeline by freezing a medium passing through it, for which a shell-and-tube cooler is used, comprising a housing with nozzles, inside which a tube bundle 1 is located.
Недостатком этого устройства вл ютс большие габариты и то, что трубки, установленные в трубопроводе, оказывают большое гидравлическое сопротивление потоку теплоносител .A disadvantage of this device is the large size and the fact that the pipes installed in the pipeline have a large hydraulic resistance to the flow of the coolant.
Известно также устройство дл перекрыти трубопровода посредством замораживани проход щей по нему среды, содержащее размещенный на трубопроводе и образующий с НИ.М кольцевую камеру корпус с патрубками дл подвода и отвода охлаждающей среды 2.It is also known a device for shutting off a pipeline by freezing a medium passing through it, comprising a housing arranged on the pipeline and forming an annular chamber with the H.M.M with connections for inlet and outlet of the cooling medium 2.
Недостатком данного устройства вл етс то, что теплоноситель, замороженныйThe disadvantage of this device is that the coolant, frozen
в трубопроводе (пробка теплоносител ), может быть выбит ударной волной, возникающей при взаимодействии натри с водой в парогенераторе.in the pipeline (heat carrier plug), can be knocked out by the shock wave that occurs when sodium interacts with water in the steam generator.
Целью изобретени вл етс повышение надежности перекрыти .The aim of the invention is to improve the reliability of the overlap.
5 Эта цель достигаетс тем, что трубопровод в зоне замораживани выполнен суженным .5 This goal is achieved by the fact that the pipeline in the freezing zone is narrowed.
Изобретение по сн етс чертежом.The invention is illustrated in the drawing.
Устройство содержит корпус 1 с патрубками 2 и 3, установленный на трубопроводе 4, .выполненном с сужением 5.The device includes a housing 1 with nozzles 2 and 3, mounted on the pipe 4,. Performed with the restriction 5.
Устройство работает следующим образом .The device works as follows.
