Изобретение относитс к узлам креплени труб в трубных решетках теплообменников и может быть использовано в энергетике н других област х промышленности.The invention relates to pipe fasteners in tube sheets of heat exchangers and can be used in power engineering and other industrial fields.
Известны узлы креплени труб в трубных решетках теплообменников, содержащие распорные элементы в виде усеченного конуса, сопр женного наружной поверхностью с конической частью внутренней поверхности концевого участка трубы, установленного в цилиндроконическом отверстии решетки }.Known attachment points for tubes in heat exchanger tube grids are those that contain spacer elements in the form of a truncated cone, which are mated by an outer surface with a conical part of the inner surface of an end section of a tube installed in a cylindrical conical opening of the grate}.
Недостаток указанных узлов заключаетс в недостаточно надежности герметизации и сложности конструкции.The disadvantage of these assemblies lies in the lack of reliable sealing and design complexity.
Цель изобретени - повышение надежност 1 герметизации и упрощение конструкции .The purpose of the invention is to increase the reliability of sealing 1 and simplify the design.
Это достигаетс тем, что распорный эЛемент со стороны меньшего основани снабжен цилиндрическим хвостовиком, сопр жеинЫм наружной поверхностью с соответствующей внутренней поверхностью концевого участка трубы, а со стороны большего основани - коническим буртом, контактирующим с коническим участком отверсти и торцовой поверхностью концевого участка трубы ..This is achieved by the fact that the expansion element on the side of the smaller base is provided with a cylindrical shank, a matching outer surface with a corresponding inner surface of the pipe end section, and on the side of the larger base a conical collar in contact with the conical hole section and the end surface of the pipe end section.
На чертч же схематически изображен описываемый узел. The drawing also shows the node described schematically.
Узел содержит распорный злемент I в виде усеченного конуса, сопр женного наружной поверхностью с конической частью наружной поверхност-и концевого участка трубы 2, установленного в цилнндрокоиическом отверстии решетки 3. Распорный элемент 1 со стороны меньшего основани снабжен цилиндрическим хвостовиком 4, сопр женным наружной поверхностью с соответствующей внутренней поверхностью концевого участка трубы 2, а со стороны большего основани - коническим буртом 5, контактирующим с коническим участком отверсти и торцевой поверхностью концевого участка трубы 2.The assembly contains a spacer element I in the form of a truncated cone mated by the outer surface with the conical part of the outer surface and end section of the pipe 2 installed in the cylindrical hole of the lattice 3. The spacer 1 on the side of the smaller base is provided with a cylindrical shank 4 adjoining the outer surface the corresponding inner surface of the end section of the pipe 2, and from the side of the larger base - the conical shoulder 5, which is in contact with the conical section of the hole and the end surface the end portion of the tube 2.
