Abstract
Высокогерметичное резьбовое соединение труб включает охватываемую и охватывающую трубчатые детали с резьбами и упорными торцами, наружную и внутреннюю уплотнительные поверхности. На внутренней поверхности охватывающей детали со стороны ее свободного торца выполнен участок конусной формы, являющийся фаской и на котором выполнен сход резьбы, при этом поверхность указанного торца выполнена конусной с уклоном в сторону внешней поверхности охватывающей детали относительно вертикальной плоскости, проходящей поперек оси охватывающей детали, является ответной для конусной упорной поверхности торца охватываемой детали, и имеет участок перехода, от зоны полной резьбы к уплотнительной внутренней поверхности, выполненной конусной с расположением вершины конуса на оси охватывающей детали, причем участок перехода, связанный с участком с полной резьбой, выполнен цилиндрическим с диаметром, большим диаметра резьбы, или в виде треугольной в сечении канавки, одна из наклонных стенок которой является участком схода резьбы, а на внешней поверхности охватываемой детали последовательно со стороны открытого торца выполнены ответная уплотнительной внутренней поверхности охватывающей детали уплотнительная наружная конусная поверхность и участок с полной резьбой выполнен с фасками в местах схода и связан с конусной торцевой поверхностью этой детали.The high-pressure threaded pipe joint includes the male and female tubular parts with threads and abutting ends, and external and internal sealing surfaces. On the inner surface of the female part, on the side of its free end, there is a conical shape section, which is a facet and on which a thread is drawn; reciprocal for the conical thrust surface of the end of the covered part, and has a transition section, from the full thread zone to the sealing inner surface, oh conical with the location of the apex of the cone on the axis of the female part, the transition section associated with the full thread section is cylindrical with a diameter greater than the thread diameter, or in the form of a groove triangular in section, one of the inclined walls of which is a section of the thread on the outer surface of the male part, a sealing outer inner surface and a section with a full thread are made in response to the open end of the male part; the battle is made with chamfers in places of vanishing and is associated with the conical end surface of this part.
