Abstract
The invention discloses a horizontal type expansion joint of a double large draw bar. The technical scheme of the horizontal type expansion joint is realized in such a way that the horizontal type expansion joint comprises end connecting pipes, two corrugated pipes, honeycomb ducts, two groups of large draw bars, a middle connecting pipe, nut combination pieces, flange plates and reinforcing rings, wherein the two corrugated pipes are axially connected with the two ends of the middle connecting pipe, the other ends of the two corrugated pipes are axially connected with the end connecting pipes respectively, the reinforcing rings are arranged at the connecting parts of the corrugated pipes and the end connecting pipes as well as the middle connecting pipe, the honeycomb ducts are arranged in the corrugated pipes, the large draw bars pass through a vertical plate on the middle connecting pipe and are fixed to the flange plates fixedly connected onto the outer surfaces of the two end connecting pipes via the nut combination pieces, and the two groups of large draw bars are symmetrically distributed at the two sides of the expansion joint. The horizontal type expansion joint has the beneficial effects that the expansion joint can be used for compensating lateral displacement vertical to a pipeline, a running piping or a container and the like caused by such factors as thermal expansion in the axis direction, and is particularly suitable for L-shaped and Z-shaped piping systems; a displacement spherical nut rotates around a spherical washer, thereby enabling the draw bars to have the capability of bearing internal-pressure thrust.
Description
Technical field
The present invention relates to expansion joint application, relate in particular to a kind of compound BHU expansion joint.
Background technique
In non-straight pipeline, especially in " L " type, " Z " type pipeline perpendicular to pipeline, conveyance conduit or container etc. along the pipeline that causes lateral displacement on its axial direction because of thermal expansion etc., need a kind of expansion joint that can absorb lateral displacement stress solve.
Summary of the invention
The object of this invention is to provide a kind of compound BHU expansion joint, be applicable to compensation perpendicular to pipeline, conveyance conduit or container etc. along on its axial direction because of caused lateral displacements such as thermal expansions, be particularly useful in " L " type, " Z " type piping.
To achieve these goals, technological scheme of the present invention is achieved in that compound BHU expansion joint, it comprises pipe nipple 1, bellows 2, honeycomb duct 3, large pull bar 4, middle adapter 5, nut assembly 6, flange plate 7, stiffening ring 8, described bellows 2 has two, described bellows 2 is axially connected to the two ends of described middle adapter 5, described bellows 2 the other ends axially connect respectively again a described pipe nipple 1, described bellows 2 and described pipe nipple 1, the joint of middle adapter 5 is provided with stiffening ring 8, respectively on described bellows 2 inwalls be laterally provided with a described honeycomb duct 3, described large pull bar 4 through the described riser 9 in described middle adapter 5 with to be fixedly connected on described flange plate 7 on the outer surface of two described pipe nipples 1 fixing by described nut assembly 6, described large pull bar 4 has two groups, be symmetrically distributed in the both sides of described compound BHU expansion joint.
Further, described nut assembly 6 is displacement Ball faced nut and spherical washer composition.
Further, the making material of described large pull bar 4 can be metal, plastics or rubber.
Further, described compound lateral mode expansion joint is that metallic material is made.
Further, two described bellowss 2 are that wave number is identical, the corrugated stainless steel tubing that rigidity is consistent.
The present invention has following beneficial effect: the present invention be applicable to compensation perpendicular to pipeline, conveyance conduit or container etc. along on its axial direction because of caused lateral displacements such as thermal expansions, be particularly useful in " L " type, " Z " type piping.Wherein, the ingenious application of nut assembly, because displacement Ball faced nut rotates around spherical washer, makes pull bar also have the ability of bearing interior pressure thrust.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
With reference to accompanying drawing 1 description of symbols: 1, pipe nipple, 2, bellows, 3, honeycomb duct, 4, large pull bar, 5, middle adapter, 6, nut assembly, 7, flange plate, 8, stiffening ring.
