Изобретение относитс к теплооОменным аппаратам, конкретно к узлам креплени труб в трубных решетках теплообменников.The invention relates to heat exchangers, in particular to pipe attachment assemblies in tube grids of heat exchangers.
По основному авт. св. № 69939 известен узел креплени трубы в трубной решетке теплообменника, содержащий установленные в цилиндрическом отверстии резьбовую втулку и промежуточный элемент. При этом наружна поверхность концевого участка сопр жена с коническим участком отверсти , а промежуточный элемент выполнен металлическим и размещен между внутренней поверхностью концевого участка трубы и втулкой, причем поверхность промежуточного элемента, сопр женна с концевым участком трубы, выполнена конической 1 .According to the main author. St. No. 69939 a knot for fastening a pipe in a tube plate of a heat exchanger, comprising a threaded sleeve and an intermediate element installed in a cylindrical bore, is known. In this case, the outer surface of the end section is mated with the conical hole section, and the intermediate element is made of metal and placed between the inner surface of the pipe end section and the sleeve, and the surface of the intermediate element, which is conjugated with the pipe end section, is made conical 1.
Недостатком указанного узла вл етс невысока надежность герметизации .The disadvantage of this node is the low reliability of the seal.
Цель изобретени - повышени надежности герметизации.The purpose of the invention is to improve the reliability of sealing.
Указанна цель достигаетс тем, что промежуточный элемент и втулка , сопр жены между собой по сферической поверхности.This goal is achieved by the fact that the intermediate element and the sleeve are connected to each other along a spherical surface.
На чертеже изображен предлагаемый узел, продольный разрез.The drawing shows the proposed site, a longitudinal section.
Узел креплени трубы 1 в трубной решетке 2 теплообменника содержит ус10 тановленные в цилиндрическом отверстии резьбовую втулку 3 и промежуточный элемент k. Наружна поверхность концевого участка трубы 1 сопр жена с коническим участком отверсти , а The fastening assembly of the pipe 1 in the tube sheet 2 of the heat exchanger comprises a threaded sleeve 3 and an intermediate element k installed in a cylindrical bore. The outer surface of the end section of the pipe 1 is in contact with the conical hole area, and
ts промежуточный элемент выполнен металлическим и размещен между внутренней поверхностью концевого участка трубы 1 и втулкой 3. Поверхность 5 промежуточного элемента , сопр женна ts the intermediate element is made of metal and is placed between the inner surface of the end section of the pipe 1 and the sleeve 3. The surface 5 of the intermediate element is interfaced
