Abstract

Изобретение может быть использовано при строительстве трубопроводов с теплоизол цией. Цель изобретени  - облегчение монтажа - демонтажа цилиндрического соединени  дл  концов двух концентрических труб. Промежуточна  вставка выполнена в виде горизонтальной Y-образной вилки с цилиндрическим кольцом (К) 7 у основани  полок. Внутренн   полка своим цилиндрическим К 7 приварена встык к концу внутренней трубы 2. Цилиндрическое К 10 наружной полки закруглено по радиусу через промежуточное К 11 в виде усеченного конуса до К 12. На поверхности К 7, 12 выполнены соответственно наружна  и внутренн   резьбы, сопр гаемые между собой. Вставка может состо ть только из наружной полки. На наружной поверхности трубы 2 выполнена резьба, сопр женна  с резьбой полки. 1 з.п. ф-лы. 5 ил.The invention can be used in the construction of pipelines with thermal insulation. The purpose of the invention is to facilitate installation - disassembly of a cylindrical connection for the ends of two concentric pipes. The intermediate insert is made in the form of a horizontal Y-shaped plug with a cylindrical ring (K) 7 at the base of the shelves. The inner shelf with its cylindrical K 7 is butt-welded to the end of the inner pipe 2. The cylindrical K 10 of the outer shelf is rounded radially through the intermediate K 11 in the form of a truncated cone to K 12. On the surface of K 7, 12, there are respectively external and internal threads mated between by myself. The insert may consist only of the outer shelf. A thread is made on the outer surface of the pipe 2, which is associated with the thread of the shelf. 1 hp f-ly. 5 il.

Изобретение относитс  к строительству трубопроводов преимущественно с теплоизол цией.The invention relates to the construction of pipelines mainly with thermal insulation.

Цель изобретени  - облегчение монтажа-демонтажа The purpose of the invention is to facilitate installation and dismantling.

Па фиг.1 показан трубопровод, вы- полненный из заготовок, использующих предлагаемое соединение, частичный вид, продольный разрез; на фиг.2 - разрез А-А на фиг.1; на фиг.З - узел I на фиг.2; на Лиг.4 - трубопровод, выполненный с использованием предлагаемого соединени , частичный вид в перспективе с вырезом; на Лиг.5 - то же, частичный вид, продольный разрезPa Fig.1 shows a pipeline made from blanks using the proposed connection, a partial view, a longitudinal section; figure 2 - section aa in figure 1; fig.Z - node I in figure 2; in Lig.4, a pipeline constructed using the proposed connection, a partial perspective view with a notch; on Lig.5 - the same, partial view, longitudinal section

Предварительно изготовленные отрезки 1 труб соединены между собой встык при помощи сварки. Каждый из отрезков 1 состоит из двух концентрических труб 2 и 3, причем диаметр внутренней трубы 2 равен диаметру трубопровода. Трубы 2 и 3 соедин ютс  одна с другой на их концах при помощи идентичных цилиндрических соединений 4, которые соедин ютс  встык на трубах при помоши сварки 5 и 6.Pre-made pieces of pipe 1 are interconnected end to end by welding. Each of the segments 1 consists of two concentric pipes 2 and 3, and the diameter of the inner pipe 2 is equal to the diameter of the pipeline. The pipes 2 and 3 are connected to each other at their ends with the help of identical cylindrical joints 4, which are butt-joined to the pipes by welding 5 and 6.

Соединени  4 имеют продольное сечение образующей, которое имеет форму горизонтальной Y-образной вилки и состо-ит из двух отдельных полок (фиг.2 и 3), которые могут быть соединены одна с другой при помощи резьбы , из которых перва  полка соединени  образована внутренним цилиндрическим кольцом 7, соедин емым встык при помощи сварки 5 на конце внутренней трубы 2 отрезков 1 .Connections 4 have a longitudinal section of the generatrix, which has the shape of a horizontal Y-shaped plug and consists of two separate shelves (Figures 2 and 3), which can be connected to one another by means of a thread, from which the first joint flange is formed by an internal cylindrical ring 7, butt-joint by welding 5 at the end of the inner pipe 2 segments 1.

Кольцо 7 снабжено на его внешней поверхности резьбой 8 (фиг.З), предназначенной дл  взаимодействи  с сопр женной резьбой 9, выполненной на второй полке, образующей соединение 4.The ring 7 is provided on its external surface with a thread 8 (FIG. 3), designed to interact with a mating thread 9, made on the second shelf forming connection 4.

Втора  полка соединени  4 образуетс  внешним цилиндрическим кольцом 10, соединенным встык при помощи сварки 6 с конним внешней трубы 3 от IThe second junction shelf 4 is formed by an outer cylindrical ring 10, butt-joined by welding 6 to the outer pipe 3 from I
