Description
говечности эластичным материалом 7 и теплоизол ционной газонепроницаемой тка.нью 8.with elastic material 7 and heat insulating gas-tight fabric 8.
Тор|Цы уплотнений, наход щиес в непосредственной близости к лх .наружным кромкам , где укреплены волнообразные упругие кольца 6, смо-нтир-ованы на разжимных элементах , а торцы, «аход щиес в иепосредстванной близости к внутренним кромкам, плотно соединены с корпусом 4 центрирующего механизма.Tops of seals located in close proximity to the outer edges, where wavy elastic rings 6 are strengthened, are mounted on the expanding elements, and the ends, “located in the immediate vicinity of the inner edges, are tightly connected to the body 4 centering mechanism.
Работа внутреннего центратора осуществл етс следующим образом.The operation of the internal centralizer is carried out as follows.
При включении привода 2 ж,имки 5 левого цантрирующего |р да (см. фиг. I) выдвигаютс из корпуса и упираютс во внутреннюю поБ-ерх.ность трубы. Затем общеизвестными и пр|Имен емыми на строительстве трубопроводов методами осуществл етс еаводка на центратс.р пристыковываемой трубы. После этого выдБИгаггтс правый центр|И|р)ющий р д, фиКсиру стык в нео бходимом дл начала сварки полол ении.When the drive 2 is turned on, the ims 5 of the left centering | p and d (see Fig. I) slide out of the housing and abut against the internal per-bosity of the pipe. Then the well-known and pr | Named on the construction of pipelines methods is carried out on the centra.r. docked pipe. After this, the right center of the right-to-right, fuzzy joint at the polishing required for the start of welding is made.
,Волдообра Зна упругих колец уплотнений необходима дл компенсации измен ющегос рассто ди между жймками одного центрирующего р да, двигающимис по радиусу от центра.Voldobrand The sign of elastic seal rings is necessary to compensate for the varying distance between the strands of one centering row moving radially from the center.
Наружные кромки эластичных элементов уплотнений выступают за жимки на некоторую величину Д, что обеспечивает плотное прилегание к внутренней поверхности трубы.The outer edges of the elastic elements of the seals protrude beyond the clamp by a certain amount D, which ensures a tight fit to the inner surface of the pipe.
изолиру Свариваемый стык от внутренлего npocTipaHCTBa трубопровода.Isolate Weldable joint from the internal npocTipaHCTBa pipeline.
После окончани сборки стыка можно одновременно производить сварку далного стыка снаружи и внутреннюю сварку соседних стыков или производить необходимые работы внутри трубопровода.After completion of the joint assembly, it is possible to simultaneously perform welding of the far joint from the outside and internal welding of adjacent joints or to perform the necessary work inside the pipeline.
После этого разжим,ные элементы с уплотнени ми убираютс вплотную к корпусу, что исключает иэнос уплотнений во врем передвижени цент|ратора от стыка к стык}.Thereafter, the unclamping of the sealed elements is retracted against the body, which eliminates the sealing of the seals during the movement of the center from the joint to the joint}.
