Изобретение относитс к типу герметических неразъемных соединений, получаемых методом раззальцовки, в особенности, при соединении труб с тр|убами или с трубнымиThe invention relates to the type of hermetic one-piece joints obtained by the method of flaring, especially when joining pipes with pipe or pipe.
досками, работающими под воздействием термсцшшических нагрузок, и может найтиworking under the influence of thermal loads, and can find
широкое применение в тюлвгаеской и энергетической промышленностшг.wide application in the industry and energy industry.
Р звестно неразъемное развальцованное соединение трубы с трубой, в котором конец внутренней трубы со стороны торца вьгаолнен с кольцевым выступом, а наружна труба-с ответной торцовой канавкой с образованием торцового замка на выходном участке соединени с конусным переходом. Однако в этой конструкции выполнен торцовый замок только в одном месте и возможно местное разуплотнение соединени на входном участке соединени пои длительном термоцнклическом воздейс гвии, когда соедин емые элементы вьшо нены из материалов с различными коэффициентами температурного расширени .The well-known flared joint of a pipe with a pipe is known, in which the end of the inner pipe from the end face is filled with an annular protrusion, and the outer pipe with a counter end groove with the formation of an end lock at the outlet section of the joint with a tapered junction. However, in this construction, an end lock is made only in one place and local decompression of the joint at the entrance of the joint is possible due to prolonged thermal effects when the connected elements are made of materials with different coefficients of temperature expansion.
Разуплотнение происходит вследствие то го, что при периодическом нагреве до опре- Decompaction occurs due to the fact that with periodic heating to a certain
деленной температуры или при охлаждении величины линейных перемещений в радиальном направлении обхватывающего и охватываемого элементов неодинаковы. Это вл етс причиной возникновени в зоне соединени усилий и напр жений, вли ющих на ршскрытие места контакта соедин емых элементов .divided temperature or when cooled, the magnitudes of linear displacements in the radial direction of the grasping and covered elements are different. This is the reason for the occurrence in the area of the connection of forces and stresses that affect the opening of the contact point of the connected elements.
Предлагаемое соединение отличаетс тем, что оно допо-шительно снабжено торцовым замком на входном участке соединени наружна труба которого выполнена с кольцевым выступом, а внутренн - с опытной кольцевой канавкой, причем переходный конус от этого замка к соединению напра&лен навстречу переходному конусу замка.The proposed connection is characterized in that it is additionally provided with an end lock at the entrance of the connection, the outer pipe of which is made with an annular protrusion, and the internal one with an experienced ring groove, the transitional cone from this lock towards the connection facing the transitional cone of the lock.
