Нй  втулки и гильзы болт 5 освобождаетс . На конце одного соедин емого трубопровода остаетс  втулка 3 с насадкой 6 внутри нее, на конце другого - ось 1 с гильзой Inlet sleeves and sleeves bolt 5 is released. At the end of one connected pipeline there is a sleeve 3 with a nozzle 6 inside it, at the end of the other - an axis 1 with a sleeve 2. Каналы дл  рабочей среды при этом остаютс  перекрытыми. Последовательность сборки обратна . Насадка 6 с втулкой 3 на ней крепитс  болтом 5 к оси 1. Втулка перемещаетс  по оси, сдвига  гильзу 2 на свободный конец оси до соприкосновени  с буртом оси. Болт 5 освобождаетс , насадка устанавливаетс  буртом к оси и снова крепитс  болтом. Выполнение шарнирного соединени  дл  трубопроводов предлагаемым способом позвол ет исключить утечку рабочей жидкости из каналов дл  рабочей среды элементов соединени  во врем  рассоединени  и присоединени  этих элементов и в рассоединенном состо нии шарнира. Кроме того, позвол ет исключить возможность попадани  воздуха и загр знений в гидросистему, возникающую во врем  рассоединени , присоединени  и в рассоединенном состо НИИ шарнира. Это снижает возможиойть Засорени  гидросистемы, увеличива  тем самым надежность и долговечность ее работы . Формула изобретени  Шарнирное соединение дл  трубопроводов , содержащее взаимно подвижные втулку с уплотнени ми и удлиненную ось, имеющую каналы дл  рабочей среды, а также запорный элемент, отличающеес  тем, что, с целью сохранени  герметичности обоих трубопроводов в рассоединенном состо нии , запорный элемент выполнен в виде насадки с диаметром, равным диаметру оси, и прикрепленной к ее торцу, и гильзы с уплотнени ми, подвижно одетой на ось, а втулка расположена между гильзой и насадкой и снабжена каналами дл  рабочей среды, сообщающимис  с каналами оси. Источники информации, прин тые во внимание при экспертизе 1. Авторское свидетельство СССР № 428152, кл. F 16L 29/00, 1971.2. The channels for the working medium remain closed. The assembly sequence is reversed. The nozzle 6 with the sleeve 3 on it is attached with the bolt 5 to the axis 1. The sleeve moves axially, sliding the sleeve 2 to the free end of the axis until it touches the axis shaft. The bolt 5 is released, the nozzle is installed with a collar to the axis and is again attached with a bolt. Making a swivel joint for the pipelines of the proposed method eliminates the leakage of working fluid from the channels for the working medium of the connecting elements during the disengagement and attachment of these elements and in the uncoupled state of the hinge. In addition, it eliminates the possibility of air and contamination entering the hydraulic system that occurs during disengagement, connection, and in the disconnected state of the research institute of the hinge. This reduces the potential for clogging up the hydraulic system, thereby increasing the reliability and durability of its operation. Claims An articulated joint for pipelines containing mutually movable bushings with seals and an elongated axis having channels for the working medium, as well as a locking element, characterized in that, in order to preserve the tightness of both pipelines in the disconnected state, a nozzle with a diameter equal to the diameter of the axle and attached to its end, and a sleeve with seals movably mounted on the axle, and the sleeve is located between the sleeve and the nozzle and provided with channels for the working medium telling IS with axis channels.
