Description

Область, к которой относится полезная модельArea to which the utility model belongs

Полезная модель относится к области монтажа и ремонта полимерных трубопроводов и может быть использована для сварки встык последнего стыкового соединения во время ремонта полимерных трубопроводов при стесненных условиях.The utility model relates to the field of installation and repair of polymer pipelines and can be used for butt welding of the last butt joint during the repair of polymer pipelines under cramped conditions.

Уровень техникиState of the art

Известно техническое решение (1. СП 40-101-96 Проектирование и монтаж трубопроводов из полипропилена "Рандом сополимер", п. 2), в котором последний стык при ремонте полимерных труб сваривают обычным нагревателем для стыковой сварки с использованием петлеобразных (круговых) компенсаторов для труб небольшого диаметра.A technical solution is known (1. SP 40-101-96 Design and installation of pipelines from polypropylene "Random copolymer", p. 2), in which the last joint for repair of polymer pipes is welded with a conventional butt welding heater using loop-shaped (circular) compensators for small diameter pipes.

Недостатком данного технического решения является невозможность его использования для сварки последнего стыка между двумя вмонтированными в трубопровод трубами диаметром свыше 50 мм.The disadvantage of this technical solution is the impossibility of its use for welding the last joint between two pipes mounted in the pipeline with a diameter of more than 50 mm.

Наиболее близким является техническое решение (2. СП 42-103-2003 Проектирование и строительство газопроводов из полиэтиленовых труб и реконструкция изношенных газопроводов, п. 6.68), в котором последний стык в стесненных условиях сваривают муфтой с закладным нагревательным элементом.The closest is the technical solution (2. SP 42-103-2003 Design and construction of gas pipelines from polyethylene pipes and reconstruction of worn-out gas pipelines, p. 6.68), in which the last joint is welded in a cramped condition with a built-in heating element.

Недостатком указанного технического решения является то, что для такой сварки требуется отдельное сварочное оборудование и дорогостоящая муфта.The disadvantage of this technical solution is that for such welding requires separate welding equipment and an expensive coupling.

Раскрытие полезной моделиUtility Model Disclosure

Задачей заявляемой полезной модели является нагреватель, используемый для стыковой сварки, в том числе и для сварки последнего стыка в стесненных условиях.The objective of the claimed utility model is a heater used for butt welding, including for welding the last joint in cramped conditions.

Технический результат, получаемый при реализации полезной модели, заключается в том, что для монтажа и ремонта полимерных трубопроводов используется только один и тот же нагреватель для стыковой сварки без применения муфт.The technical result obtained by the implementation of the utility model is that for the installation and repair of polymer pipelines only the same heater is used for butt welding without the use of couplings.

Существенные признаки, характеризирующие полезную модель.The essential features that characterize the utility model.

Ограничительные: нагреватель для стыковой сварки, у которой плоские поверхности нагреты до температуры оплавления торца полимерной трубы.Restrictive: a heater for butt welding, in which flat surfaces are heated to the fusion temperature of the end of the polymer pipe.

Отличительные: нагреватель, состоящий из двух шарнирно соединенных пластин, имеет на боковой стороне планку с пазом, фиксируемый болтами для выдерживания заданного угла нагретых пластин.Distinctive: the heater, which consists of two pivotally connected plates, has on the side a bar with a groove fixed by bolts to withstand a given angle of heated plates.

Краткое описание чертежаBrief Description of the Drawing

На фиг. 1 приведен нагреватель. На фиг. 2 приведена схема сварки последнего стыка при ремонте трубопровода.In FIG. 1 shows the heater. In FIG. 2 shows a diagram of the welding of the last joint during pipeline repair.

Осуществление полезной моделиUtility Model Implementation

В нагревателе для стыковой сварки параллельные плоскости нагреваются до температуры оплавления торцов свариваемых труб. Для соединения двух полимерных труб нагреватель размещают между торцами этих труб и оплавляют торцы. Затем удаляют нагреватель и трубы прижимают оплавленными торцами друг к другу. При ремонте полимерного трубопровода последний стык в стесненных условиях сваривается муфтой с закладным нагревательным элементом, для сварки которого требуется специальное сварочное оборудование. Раздвижение торцов свариваемых трубопроводов для размещения между ними нагревателя и последующего сжатия оплавленных торцов труб для соединения (сварки) невозможно, так как кроме ремонтируемого участка трубы трубопровод бывает закопанным или настолько длинным, что невозможно его двигать вдоль линии укладки.In a butt welding heater, parallel planes are heated to the fusion temperature of the ends of the pipes being welded. To connect two polymer pipes, a heater is placed between the ends of these pipes and the ends are melted. Then the heater is removed and the pipes are pressed by the molten ends to each other. When repairing a polymer pipeline, the last joint in cramped conditions is welded by a sleeve with a built-in heating element, for welding of which special welding equipment is required. The extension of the ends of the welded pipelines to place a heater between them and the subsequent compression of the molten ends of the pipes for connection (welding) is impossible, since in addition to the repaired pipe section, the pipeline is buried or so long that it cannot be moved along the laying line.

Нагреватель для сварки полимерных труб, состоящий из двух пластин 1 (фиг. 1) соединенных шарниром 2 и питающийся от источника электроэнергии через кабель 6. на боковой стороне имеет планку 3 с пазом, которая фиксируется болтами 4 для выдерживания заданного угла. При обычной стыковой сварке трубопровода наружные плоские поверхности 5 обеих пластин 1 фиксируются параллельно. При использовании предлагаемого нагревателя при сварке последнего стыка ремонтируемого полимерного трубопровода наружные плоские поверхности нагрева 5 (фиг. 2) фиксируются с учетом угла отклонения труб друг от друга (не показано) и глубины оплавления обеих свариваемых торцов, выкопанных из земли участков трубы и обрезанных под углом так, что при соединении после оплавления стенки соединяемых труб составляли как продолжение друг друга. При использовании предлагаемого нагревателя будет исключена необходимость передвижения трубы вдоль линии проложения, а также отпадает использование другого сварочного оборудования и муфты с закладным нагревательным элементом.A heater for welding polymer pipes, consisting of two plates 1 (Fig. 1) connected by a hinge 2 and powered by a power source through cable 6. On the side has a bar 3 with a groove, which is fixed with bolts 4 to maintain a given angle. In conventional butt welding of the pipeline, the outer flat surfaces 5 of both plates 1 are fixed in parallel. When using the proposed heater when welding the last joint of the polymer pipe being repaired, the outer flat heating surfaces 5 (Fig. 2) are fixed taking into account the angle of deviation of the pipes from each other (not shown) and the depth of fusion of both ends to be welded, sections of the pipe dug from the ground and cut at an angle so that when connected after reflow, the walls of the pipes to be connected were constituted as an extension of each other. When using the proposed heater, the need to move the pipe along the laying line will be eliminated, and the use of other welding equipment and a coupling with a built-in heating element will be eliminated.

Таким образом, для монтажа и ремонта полимерных трубопроводов используется только один и тот же нагреватель для стыковой сварки.Thus, for the installation and repair of polymer pipelines, only the same butt welding heater is used.
