Abstract
Изобретение относится к области нефте- и газодобычи. Соединение содержит охватываемый и охватывающий элементы, на концах которых выполнены упорные трапецеидальные резьбы с конусностью 1:16, углом наклона закладной грани профиля витка 10-30° к нормали осевой линии резьбы и углом наклона опорной грани - от 0 до -10°. Внешний герметизирующий узел образован радиальными уплотнительными поверхностями, выполненными под углом 7-12° к осевой линии резьбы, и упорными торцевыми поверхностями, выполненными под углом 5-17° к нормали осевой линии резьбы. Внутренний герметизирующий узел образован радиальными уплотнительными поверхностями, выполненными под углом 1,5-4,0° к осевой линии резьбы. На длине, равной 20-40% от общей длины резьбы, выполненной на охватываемом элементе, начиная от захода резьбы, осуществлено протачивание резьбы с уменьшением ее высоты до 50% от полной высоты профиля резьбы. На охватывающем элементе на сходе резьбы выполнена окружная канавка, переход от поверхности которой к радиальной уплотнительной поверхности выполнен сферическим. Достигается газогерметичность соединения при действии разнонаправленных нагрузок, улучшение характеристик свинчиваемости соединения, увеличение его износостойкости.The invention relates to the field of oil and gas production. The joint contains male and female elements at the ends of which persistent trapezoidal threads with a taper of 1:16 are made, the angle of inclination of the embedded face of the coil profile is 10–30 ° to the normal of the axial line of the thread and the angle of inclination of the supporting face is from 0 to –10 °. The outer sealing assembly consists of radial sealing surfaces made at an angle of 7-12 ° to the axial line of the thread, and abutting end surfaces made at an angle of 5-17 ° to the normal of the axial line of the thread. The inner sealing assembly consists of radial sealing surfaces made at an angle of 1.5-4.0 ° to the axial line of the thread. At a length equal to 20-40% of the total length of the thread, made on the male element, starting from the start of the thread, the thread is threaded down to 50% of the full height of the thread profile. A circumferential groove is made on the female element at the same thread, the transition from the surface of which to the radial sealing surface is spherical. A gas-tightness of the joint is achieved under the action of multidirectional loads, an improvement in the characteristics of the joint's fastability, an increase in its wear resistance.
