Description

1
Изобретение относитс  к типу герметических неразъемных соединений, получаемых методом раззальцовки, в особенности, при соединении труб с тр|убами или с трубными
досками, работающими под воздействием термсцшшических нагрузок, и может найти
широкое применение в тюлвгаеской и энергетической промышленностшг.
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 .
Разуплотнение происходит вследствие то го, что при периодическом нагреве до опре-
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 .
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.
На чертеже изобр ажено предложенное соединение, общий вид.

Claims (2)

  1. Герметичное развальцованное соединение содержит наружную трубу 1 и внутреннюю трубу 2. Конец трубы 2 со стороны торца 3 выполнен с кольцевым выступом 4, а труба 1 с ответной торцовой канавкой 5, образу  замок 6 на выходном участке соеднени  7. На входном участке соединени  7 труба 1 имеет также кольцевой выступ 8, а труба 2 - ответную канавку 9, т, е. образован дополнительный замок 1О. Переходный конус 11 расположен от замка 6 к соединению 7, а переходный конус 12 от замка 10 к соединению 7, причем конус 12 направлен навстречу конусу 11. Материалы труб 1 и 2 имеют различные коэффициенты температурного расширени . Это соединение получают следующим об- разом, В трубу 1 завод т трубу 2, при этом кольцевой выступ 4 трубы 2 входит в кольцевую канавку 5 трубы 1, а выступ 8 трубы 1 - в канавку 9 трубы 2. Сопр гаемые поверхности труб 1 и 2 образуют соединение 7 по переходной посадке. Собранную конструкцию развальцовывают При таком исполнении соединени  и любом сочетании коэффициентов температурного расширени  элементов соединени  7 кольце- вой выступ 8 трубы 1  вл етс  преп тствующим звеном дл  свободного перемещени  трубы 2 с ответной кольцевой канавкой 9 в радиальном направлении. В этом случае радиальное перемещение одной трубы копируетс  второй трубой. Это обеспечивает гарантию сохранени  контакта по всему соединению 7 трубы 1 и
  2. 2. Формула изобретени  Неразъемное разва.чьцованное соединение трубы с трубой, в котором конец внутренней трубы со стороны торца выполнен с кольцевым выступом, а наружна  труба - с ответной кольцевой канавкой с образованием торцового замка на выходном участке соединени  с конусным переходом, отличающеес  тем, что, с целью повышени  герметичности соединени  труб с различными коэффициентами температурного расширени  при многократном термоциклическом воздействии, оно дополнительно снабжено торцовым замком на входном участке соединени , наружна  труба которого выполнена с KonbneBbnvi выступом, а внутренн   - с ответной кольцевой канавкой , причем переходный конус от этого замка к соединению направлен навстречу переходному конусу замка, расположенного на выходном участке соединени .
