Description
Известны устройства дл предотвращени распространени аварийных процессов в трубопроводных системах, содержащие преграждающий элемент, смонтированный на трубопроводе . Цель изобретени - обеспечение прерывани процессов, имеющих большую скорость распространени . Это достигаетс тем, что преграждающий элемент выполнен в виде нетлевого участка трубопровода, содержащего две расположенные одна над другой предохранительные разрушаемые вставки из низконрочного материала . На чертеже схематически показано предлагаемое устройство. На трубопроводе / установлен преграждающий элемент, выполненный в виде нетлевого участка 2, на перекрестье которого одна над другой расположены предохранительные вставки 3 из низкопрочного материала. Аварийный процесс, возникающий в трубопроводе /, сопровождаетс выделением большого количества тепла и газов. При подходе фронта процесса к первой вставке 3, последн под действием повышенного давлени разрушаетс , а сам процесс благодар большой скорости распространени успевает пройти дальше в петлевой участок 2. Однако при разрушении первой вставки 3 под действием ударной волны разрушаетс также втора вставка 3, и при подходе фронта нроцесса ко второй вставке 3 герметичность системы будет нарушена и процесс не сможет распространитьс дальше по трубопроводу 1. После устранени аварийной ситуации разрушенные вставкн 3 замен ютс новыми, и устройство готово к дальнейн1е1 работе. Предмет изобретени Устройство дл предотвращени распространени аварийных процессов в трубопроводных системах, содержащее нреграждаю1щ-п элемент, смонтированный на трубопроводе , отличающеес тем, что, с целью обеспечени прерывани процессов, имеющих больгую скорость распространени , нреграл даю1 ,ий элемент выполнен в виде петлевого учатка трубопровода, содержащего две располоенные одна над другой предохранительные азрунтемые вставки из нпзкопрочного матеиала .Devices are known for preventing the spread of emergency processes in piping systems that contain a blocking element mounted on the pipeline. The purpose of the invention is to provide an interruption of processes having a high propagation rate. This is achieved by the fact that the blocking element is made in the form of a non-blank section of a pipeline containing two safety destructible inserts arranged one above the other of low-strength material. The drawing schematically shows the proposed device. On the pipeline / there is a blocking element installed, made in the form of a non-blank section 2, on the crosshairs of which one above the other are safety inserts 3 of low-strength material. The emergency process occurring in the pipeline / is accompanied by the release of a large amount of heat and gases. When the process front approaches the first insert 3, the latter is destroyed by the increased pressure, and the process, due to the high speed of propagation, has time to go further into the loop section 2. However, when the first insert 3 collapses, the second insert 3 also collapses under the action of the shock wave front of the process to the second insert 3, the tightness of the system will be broken and the process will not be able to spread further along pipeline 1. After the emergency situation is eliminated, the destroyed inserts 3 are replaced with new ones and The device is ready for further work. The subject of the invention is a device for preventing the spread of emergency processes in pipeline systems, comprising an obstacle-mounted element mounted on a pipeline, characterized in that, in order to ensure the interruption of processes having a high propagation velocity, an element 1 is designed, containing two located one above the other safety azrunted inserts of high-strength material.
