Изобретение относитс  к дистан1цион1ирующим элементам трубных пучков теплообменных аппаратов.The invention relates to spacer elements of tube bundles of heat exchangers.

Известны дистаиционирующие решетки дл  труб теплообменного апиарата, содержащие кольцо и укрепленные в нем взаимно пересекаюи1иес  иланки.Distributing grids for heat exchange apiarat pipes are known, which contain a ring and mutually intersecting flanks in it.

Недостатком известных решеток  вл етс  жесткое крепление плавок к кольцу, что затрудн ет монтаж и демойтаж их в случае износа.A disadvantage of the known grids is the rigid attachment of the bottoms to the ring, which makes it difficult to assemble and disassemble them in the event of wear.

Цель изобретени  - создание дистанционпруюшей решетки, исключающей износ труб в местах касани  их с дистанционируюпдими планками и обеспечивающей быструю замену дистанщионирующей планки без демонггажа трубного пучка.The purpose of the invention is to create a spacer grid, which eliminates the wear of pipes at the places where they touch them with spacer bars and ensures quick replacement of the distance plate without dismounting the tube bundle.

Эта цель достигаетс  тем, что кольцо состоит , ио меньшей мере, из двух частей, имеющих пазы дл  размещени  планок, выполненных из материала с меньшей ирочностью на истирание, чем прочность материала труб. Кольцо заключено в составной обод, части которого соединены, например, ири помощи болтов.This goal is achieved by the fact that the ring consists, and at least of two parts, having grooves for accommodating strips made of a material with a lower wear resistance than the strength of the pipe material. The ring is enclosed in a composite rim, parts of which are connected, for example, by means of bolts.

фиг. 1; на фиг. 4 представлен аксонометрический чертеж дистанционирующей решетки.FIG. one; in fig. 4 shows an axonometric drawing of the spacer grid.

Дистанционирующа  решетка, изображенна  на фиг. 1, состоит из кольца /, составленного из двух частей, имеющих пазы 2 дл  размещени  планок 3.The distance grid shown in FIG. 1 consists of a ring / composed of two parts having grooves 2 for accommodating the slats 3.

Кольцо 2 заключено в составной обод 4, части которого соедив ютс  с помощью болтов .The ring 2 is enclosed in a composite rim 4, parts of which are connected with bolts.

Дл  замены изношенных планок 3 на новые осуществл етс  разборка кольца 1 и обода 4.To replace worn strips 3 with new ones, the ring 1 and the rim 4 are disassembled.
