Изобретение относитс к эксплуатации магистральных трубопроводов,-в частности к защите водопроводов от коррозии.The invention relates to the operation of trunk pipelines, in particular, to the protection of water pipelines against corrosion.
Цель изобретени - повьшение ка- покрыти и снижение стоимости за счет использовани в качестве полимерной композиции полимерного рукава ..The purpose of the invention is to increase the coating and reduce the cost due to the use of a polymer sleeve as the polymer composition.
На фиг, 1 показано устройство дл нанесени защитного покрыти на внутреннюю поверхность трубопровода при закреплении полимерного рукава на стенке трубопровода; на фиг. 2 - то же, при закреплении тканого рукава, пропитанного полимерной композицией, на стенке трубопровода; на фиг.З - конусный упор с контактами, св занный с электроустановкой.Fig. 1 shows a device for applying a protective coating on the inner surface of the pipeline when the polymer sleeve is fixed to the wall of the pipeline; in fig. 2 - the same, when fixing a woven sleeve impregnated with a polymer composition on the pipe wall; FIG. 3 shows a tapered stop with contacts associated with an electrical installation.
Способ осуществл ют следующим образом .The method is carried out as follows.
В трубопроводе 1 размещают полимерный рукав 2, конец которого выворачивают и закрепл ют на стенке тру- бопровода. Затем устанавливают индукционный нагреватель 3, который по- средством кабел -троса 4, проход щего внутри рукава 2, и контактирующего с ним поршн 5 через барабан 6 и контакт 7 соедин ют с контактом 8, установленным на конусном ловителе 9. Размещают тканый рукав 10, пропитанный полимерной композицией, конец которого также выворачивают и закрепл ют на стенке трубопровода 1. Рукав 10 намотан на барабане 11, размещен- Мом в герметичной к,амере 12. Трубопровод .снабжен системами 13 и 14 подачи в трубопровод рабочего агента.A polymer sleeve 2 is placed in the pipe 1, the end of which is turned out and fixed to the wall of the pipe. Then, an induction heater 3 is installed, which by means of a cable, a cable 4, passing inside the sleeve 2, and a piston 5 in contact with it, is connected through the drum 6 and the contact 7 with the contact 8 mounted on a conical catcher 9. Place the woven sleeve 10, impregnated with a polymeric composition, the end of which is also turned out and fixed to the wall of the pipeline 1. The hose 10 is wound on a drum 11 placed in the sealed housing 12. The pipeline is equipped with systems 13 and 14 of supplying the working agent to the pipeline.
Барабан 6 через редуктор 15 кинематически св зан с электромотором 16, который взаимодействует с кулачковым тормозом 17. В трубопроводе установлен конусный упор 18 с контактами 19 соединенный кабелем 20 с электроустановкой 21,The drum 6 through a gearbox 15 is kinematically connected to an electric motor 16, which interacts with a cam brake 17. A conical stop 18 with contacts 19 connected by a cable 20 with an electrical installation 21 is installed in the pipeline,
Системой 14 в трубопровод 1 зака чивают сжатый воздух. Рукав 2 начинает раздуватьс и прижиматьс к стенке трубопровода. Своим торцом рукав 2 начинает перемещать поршень 5, жестко св занный с барабаном 6 и кулачковым тормозом 17.System 14 pumps compressed air into pipeline 1. The sleeve 2 begins to inflate and press against the wall of the pipeline. With its end, sleeve 2 begins to move the piston 5, which is rigidly connected to the drum 6 and the cam brake 17.
Как только конусный ловитель 9 начинает контактировать с конусным упор.ом 18, контакты 8 и 19 соедин ютс . Электрический ток подаетс на электромотор 16, который приводитAs soon as the cone catcher 9 begins to contact with the cone stop 18, contacts 8 and 19 are connected.

в действие барабан 6 и кулачковый тормоз 17. Барабан 6 начинает вращатьс , наматыва на себ кабель- трос 4. Кулачковый тормоз 17 преп тствует движению барабана 6 относительно трубопровода 1. Электрический ток по кабелю-тросу 4 подаетс на индуктор 3, который начинает нагревать стенку трубопровода, расплавл рукав 2. За счет нат жени кабел -троса 4 индуктор 3 начинает перемещатьс по трубопроводу и перестает контактировать с конечными выключател ми 22 и 23. Система 14 выключаетс , а система 13 включаетс . Сжатый воздух начинает поступать в рукав 10, который, толка индуктор 3, перемещаетс по трубопроводу и поджимаетс к расплавленному рукаву 2, и охлаж- де сь, соедин етс со стенкой трубопровода 1 .The drum 6 and the cam brake 17 are activated. The drum 6 begins to rotate by winding the cable 4. The cam brake 17 prevents the drum 6 from moving relative to the pipeline 1. Electric current through the cable 4 is fed to the inductor 3, which begins to heat the wall the pipe melted the sleeve 2. Due to the tension of the cable 4, the inductor 3 begins to move along the pipeline and ceases to contact with the end switches 22 and 23. System 14 turns off and system 13 turns on. Compressed air begins to flow into the sleeve 10, which, of course, inductor 3, moves through the pipeline and presses against the molten sleeve 2, and is cooled, connected to the wall of the pipeline 1.
Полимерный рукав может быть предварительно уложен на стенку трубопровода , а затем расплавлен путем пропуска по нему гор чего воздуха. После этого на него укладывают тканьй рукав. Полимерный рукав может быть уложен в тканый рукав. В этом случае на стенке трубопровода закрепл ют концы сразу двух рукавов, а плавление полимерного рукава осуществл ют внутри тканого, например, из угле- пластика рукава путем пропуска по нему гор чего воздуха.The polymer sleeve can be pre-laid on the wall of the pipeline, and then melted by passing hot air through it. After that, a cloth sleeve is laid on it. Polymer sleeve can be laid in a woven sleeve. In this case, the ends of the two sleeves are fixed at once on the wall of the pipeline, and the polymer sleeve is melted inside a woven, for example, carbon plastic sleeve by passing hot air through it.
