Description

(54) СПОСОБ СОЕДИНЕНИЯ ТРУБ I С ТРУБНЫМИ РЕШЕТКАМИ(54) METHOD OF CONNECTING PIPES I WITH TUBE GRILLES

Claims (1)

Изобретение относитс  к способам креплени  труб в отверсти х развальцовкой. Известен спобоб соединени  труб с труб ными решеткам, заключающимис  в том, что трубу устанавливают в отверстие трубной решетки и развальцовывают. Цель изобретени  - повысить плотность ie прочность coeдинeни i , Это достигаетс  тем, что перед вальцовкой на трубу насаживают элемент, :который в процессе развальцовки вдавли|вают трубу и трубную решетку. I На поверхности промежуточного элемен .та, контактирующей с трубой и трубной решеткой, выполнены кольцевые выступы. - На чертеже показана развальцовка тру ,бы по стади м. i Дл  соединени  трубы 1 с трубной ре|шеткой 2 на трубу насажи ают тонкостей ную втулку 3, выполненную из материала, обладающего большей твердостью, чем со:един емые материалы, и с двусторонними остроконечными кольцевыми выступами. ,а затем помещают ;трубу в отверстие ре- 1шетки, после чего производ т развальцов |ку конца трубы известным методом. В начальной стадии процесса развальцовки остроконечные выступы {тонкостенной втулки полно-ггью вдавливаютс  в ку трубы и в стенку отверсти  решет . Использование 1тонкостени втулкн/ с остроконечными кольцевыми выступами, {обладающей большей твердостью, чекутруб|на  решетка и труба, обеспечивает надеждное , герметичное .и прочное соед иетие как за счет контактных напр жений межи ду трубой и решеткой, так и за счет дополнительного уплотнени , получаемого в результате вдавливани  остроконечных кольцевых выступов в стенку отверсти  Г решетки и стенку трубы. Формула изобретени  1. Способ соединени  труб с трубны|ми решетками, заключающийс  в том что трубу устанавливают в отверстие трубной решетки и развальцовывают, от л и ч аю щ и и с   тем, что, с целью повышени  51 fiuKyi-BOCTH   щючвосш перед развальцовкой ва Tfiyey  асаживают про межуточный алвмввт, кото|  1 в процессе рвавальдовки ьдавлвваххг в трубу н тру&  ую решетку 7 2 Способ по п, 1 о т л ч а ю Ш   и с   тем, что ва поверхност  про .межуточного элемента, контактирующей с Трубой   трубной решеткой, «.гаолнены кольцевые выступы.The invention relates to methods for fastening pipes in openings by flared. A known method is the joining of pipes with tube grids, such that the tube is inserted into the hole of the tube grid and flared. The purpose of the invention is to increase the density, i.e., the strength of the compound i. This is achieved by installing an element onto the pipe before rolling, which: during the expansion process, press the pipe and the pipe grid. I On the surface of the intermediate element, in contact with the tube and tube sheet, there are annular projections. - The drawing shows the pipe flaring, in stages. I To connect pipe 1 with pipe rack 2, the tube is threaded with a thin sleeve 3, made of a material with greater hardness than with: unified materials, and with two-sided Pointed annular ledges. and then put the pipe into the hole of the re-lattice, after which the pipe end is produced by a known method. In the initial stage of the expansion process, the pointed tips (thin-walled bushings are pressed all the way into the pipe tube and into the wall of the sieve hole. The use of a thin-walled sleeve / with pointed annular protrusions {with greater hardness, check-pipe | on the grill and pipe provides a reliable, tight, and durable connection both by the contact stresses between the pipe and the grille and by the additional sealing obtained as a result of pressing the pointed annular protrusions into the wall of the opening G of the lattice and the wall of the pipe. Claim 1. A method of joining pipes with tube grids, such that the tube is installed in the tube grid opening and flared, from and to the fact that, in order to increase 51 fiuKyi-BOCTH schyuchvossh before flare Tfiyey sit down about interstitial alvmvvt, which | 1 in the process of pulling into a pipe and rubbing & lattice 7 2 The method according to p, 1 o tl ch and w and the fact that the surface of the intermediate element in contact with the pipe tube lattice, ". are filled with annular protrusions.
