Description

one

The invention relates to the field of construction of smoke pipes and can be used for. seals of transverse gaps between rigid elements of multi-faceted flexible exhaust ducts, gas ducts and other gas pipelines.

Known compensator containing lenses made of split, multi-p aloe and multi-faceted l.

The disadvantages of this compensator are that each side of the polygon (face) - and each lens is a composite of several elements (segments) articulated with two-layer overlap ends, i.e. there are a number of connections for two-layer lenses honestly the faces of the duct elements connected by compensators and the possibility of ensuring the tightness of the compensator.

The doubled thickness (double-layer) 25 of each element, lenses without elastic inserts in the connections between these elements reduces the transverse elasticity of each lens, and the multi-lens compensator makes it

cumbersome and time consuming during installation and repair.

The aim of the invention is to provide the damping of transverse strains.

This goal is achieved by the fact that the edges of the lens are rigidly fastened in pairs, and the gaps between the ends of bonded pairs are hermetically sealed with elastic hinge inserts, while the hinge inserts are multi-layered and connected to the faces at noMOu i flanges.

FIG. 1 shows a plan view of a compensator; in fig. 2. - section of the hinge insert in the plane of its symmetry, perpendicular to the longitudinal axis of the gas outlet trunk; in FIG. 3, a flange; in fig. 4 is a cross-section of the lens with insulation,

The collapsible compensator is made of a single lens, the straight sections 1 of the lens of which (the faces) are rigidly fastened with their ends at an angle equal to the angle between adjacent faces of the rigid segments of the polygonal exhaust pipe. pipes. Each face wall forming a lens with a solid-curved, rounded

the top is made of two metal sheets 2 (external and internal), and an acid-resistant and heat-resistant layer 3, which is pressed between them, for example, fluoroplastic. Metal sheets are coated on both sides with acid and heat resistant paint. The flanges 4 are rigidly attached to the free ends of the pairwise bonded faces 1 of the lens. Between the flanges of adjacent paired faces 1 of the lens, the hinge insert 5 is fixed with two similar flanges 4 inserted into it through its open outer end and aligned holes, under the bolts in the flanges of the faces 1 lens.

In order to ensure sufficient transverse elasticity of the lens at the locations of the flanges 4 in the middle of the wall of these flanges, three radial slits (see FIGS. 3) are formed, forming the half-flange 6 attached to the connecting rod 7.

. The edges of the facets 1 and the inserts 5 of the lens are filled with insulators 8 (see Fig 4) to reduce the corrosive ability of the gases. Warming harnesses are retained in the cavity with metal mesh 9.

The sealing of the gaps between the compensator lenses and the adjacent gas duct elements is accomplished by clamping mineral wool bundles 10 in these gaps, wrapped in 5 acid-resistant films (for example, foamed plastic).

Claims (2)

1. An adjustable compensator, for example, for a polygonal flue gas trunk containing a multi-layer, multifaceted lens with separable edges, is also distinguished by the fact that, in order to compensate for transverse deformations, the edges of the lens are rigidly fastened in pairs, and the gaps between the ends of the bonded the pairs are hermetically sealed with elastic hinge inserts. 2. A compensator according to claim 1, characterized in that the hinge inserts are multi-layered and connected to the faces with flanges.
