Description
Изобретение относитс к способам закреплени труб в отверсти х трубной решетки и может быть , использовано в энергетическом машиностроении.The invention relates to methods of fastening pipes in the openings of a tube sheet and can be used in power engineering.
Известны способы закреплени труб в отверсти х трубной решетки тепдообменных аппаратов, снабжена ных кольцевыми канавками, заполнен ными уплотнительным материалом, путем развальповки.Methods are known for securing pipes in the holes of the tube grid of heat exchangers equipped with annular grooves filled with sealing material by means of a flare.
Цель изобретени - повысить надежность соединени .The purpose of the invention is to increase the reliability of the connection.
Это достигаетс тем, что в качестве уплотнительного материала используют металл с упругопдастическими свойствами, например свинец , приводимый при ра звальцовке в объемно-напр женное Состо ние сжати в замкнутом объеме.This is achieved by using as the sealing material a metal with elastodastic properties, such as lead, which is given when it is folded into a volume-stressed state of compression in a closed volume.
На чертеже показан пример осуществлени способа.The drawing shows an embodiment of the method.
Б кольцевую канавку I трубной решетки 2 помещают упругопластичный металл 3, напримерB annular groove I of the tube sheet 2 is placed elastoplastic metal 3, for example
свинец, затем размещают трубу Ж, которую развальцовывают на длине превышащей ширину канавки,lead, then place the pipe W, which is flared at a length exceeding the width of the groove,
В результате развальцовка трубы по обе стороны канавки, свинец внутри канавки приводитс в объемно-напр женное состо ние сжати , что позвол ет полностью устранить зазоры и контакт помещенного в канавку металла с рабочей средой влутри теплообменного аппарата.As a result, pipe flaring on both sides of the groove, lead inside the groove is brought into a volume-stressed state of compression, which allows to completely eliminate the gaps and the contact of the metal placed in the groove with the working medium.
