Description
(54) УСТРОЙСТВО ДЛЯ РЕМОНТА ВНУТРИ КОЛОНЬЫ(54) DEVICE FOR REPAIRS INSIDE THE COLORS
ТРУБPIPE
Известно устройство дл ремонта внутри колонны труб нефт ных, вод ных и газовых скважин, включающее формирующий дорн, полую штангу, конусный пуансон, упор, разделитель , гидравлический толкатель и обраТ ный клапан. Однако такое устройство не обе печивает плотного прилегани всей поверхности расшир емого пластыр к стенке ко лонны. Цель изобретени повысить качествоA device for repairing oil, water, and gas wells inside a string of pipes is known, which includes a forming mandrel, a hollow rod, a conical punch, anvil, a separator, a hydraulic plunger, and an overflow valve. However, such a device does not both bake a snug fit of the entire surface of the expandable plaster to the wall of the column. The purpose of the invention to improve the quality
ремонта. Дл этого дорн в предлагаемом усройстве вЕзШОлнен из подвижных секторов с ограничивающими выступами, размещенными на упругой цилиндрическойдиафрагме.repair. For this, the mandrel in the proposed arrangement is excluded from the moving sectors with the limiting projections located on the elastic cylindrical diaphragm.
На чертеже показано предлагаемое уст ройство.The drawing shows the proposed device.
Оно содержит полую штангу 1, упор 2, конусный пуансон 3, разделитель 4, в корпусе 5 которого имеетс поршень 6, а также формирующий дорн, в KOgiiyce 7 которого заключены упруга диафрагма 8, подвижные секторы 9 и пружинные кольца Ю. Кроме того, устройство содержит толкающее гидравлическое устройство 11, состо щее из It contains a hollow rod 1, stop 2, tapered punch 3, separator 4, in case 5 of which there is a piston 6, and also forming a mandrel, in KOgiiyce 7 of which resilient diaphragm 8, moving sectors 9 and spring rings Y are. In addition, the device contains a hydraulic pushing device 11 consisting of
порщн 12, установленного в корпусе 13, и обратный клапан 14.Porshn 12 installed in the housing 13, and a check valve 14.
Создаваемое давление средаеас на диафрагму g котора , расшир сь, заста 1} ет перемещатьс подвижные секторы 9, Последние двига -этс до упора своих ограккчнваьо-ших выступов а. выступы корпуса 7 фор.;ирукщего дорна. Одновременно конусный uyaHCoii, которому сообщено осевое движение, входит в цилиндрический мeтaпгa ecкий пластырь и ггредварительно расшир ет его„The created pressure of the medium is on the diaphragm g which, expanding, sets 1} the moving sectors 9 to move. The last movement is as far as the stop of its blunt protrusions a. the protrusions of the hull 7 odds.; At the same time, the conical uyaHCoii, to which axial movement is reported, enters into a cylindrical mecha- nism and adds a preliminary expansion of its “
Вслед за конусным nya}jcoHOM 3 в предварительно расширенньп;. пластырь входит формирующий дорп с наружным диаметром, необходимым дл точной деформации пластььр по внзТреннему профилю ремонтируемой трубы и обеспечени плотного контакта ду ними,Following the conical nya} jcoHOM 3 in pre-expanded ;. The patch enters the forming dorp with an outside diameter necessary for accurate deformation of the plates along the external profile of the pipe being repaired and ensuring close contact with them,
Величину усили , передаваемого па секч/оры 9, регулируют изменением давпепи подг ваемой жи., Да.чьнейшее перемош.епие KOHjCHoro пуансона и формирующего а,орн« производ т подн тием труб, на которых закреплено устройство. При этом по.ча штапга 1, переметца сь вверх, приближает дно ко;:)пуса гидравлического устройства 11 к поршню 1 2, т.е. перезар жает гидравлический толкатель ОЛЯ дальнейшего использовани в случае необходимости,The magnitude of the force transmitted by the sec / ora 9 is controlled by changing the pressure of the bendable web., Yes. The most common peremesh.pee of the KOHjCHoro punch and the forming aperture is produced by lifting the pipes on which the device is fixed. At the same time, the headstand 1, the sweepers, are facing upwards, brings the bottom to; :) of the hydraulic device 11 to the piston 1 2, i.e. recharges the hydraulic pusher OLA for further use if necessary,
