Abstract
The invention discloses an angular hinged expansion joint. The expansion joint adopts the technical scheme that the angular hinged expansion joint comprises connecting pipes, a corrugated pipe, first hinge plates, second hinge plates, a pin shaft, and fixing blocks, wherein the two ends of the corrugated pipe are axially connected with the connecting pipes, one end of the first hinge plate and one end of the second hinge plate are fixed on the two fixing blocks respectively, and the other end of the first hinge plate and the other end of the second hinge plate are connected through the pin shaft. One of the two first hinge plate, one of the two second hinge plate, and the two fixing blocks form a support combination. The support combination has two groups, and the two groups are fixedly connected through the fixing blocks on the outer surface of a pipe section formed by the connecting pipes and the corrugated pipe, are parallel to the axial direction of the pipe section, and are symmetrically distributed on the two sides of the pipe section by taking the axial direction as the reference. The expansion joint has the benefits that angular deformation of high temperature pipe is compensated while the self-support problem of the expansion joint is solved, the structure is simple and the practicability is high.
Description
Technical field
The present invention relates to expansion joint application, relate in particular to a kind of angle hinge type expansion joint.
Background technique
Pipeline is at turning or the position of bend, if directly adopt the elbow of being made by welding splicing, under high-temperature condition, welding part is easily subject to temperatures involved to produce excessive thermal stress so, and directly causes the shell ring of welding part deform or damage.
Summary of the invention
The object of this invention is to provide a kind of angle hinge type expansion joint, both compensated the distortion of high-temperature pipe angle, also solved the self-supporting problem of expansion joint.
To achieve these goals, technological scheme of the present invention is achieved in that a kind of angle hinge type expansion joint, and it comprises adapter 1, bellows 2, the first hinge plate 3, the second hinge plate 4, bearing pin 5, fixed block 6.The two end axles of described bellows 2 is to connecting described adapter 1, and described adapter 1 of every end, is symmetric take described bellows 2 as reference.One end of described the first hinge plate 3 and described the second hinge plate 4 is respectively fixed on a described fixed block 7, and the other end of described the first hinge plate 3 and described the second hinge plate 4 is fixedly connected with by bearing pin 5.Form a support combinations by one, two fixed blocks 7 among, described the second hinge plate 4 among described the first hinge plate 3.Described support combinations has two groups, is fixedly connected on the outer surface of the shell ring being formed by described adapter 1 and bellows 2, and is parallel to the axial of shell ring and is symmetrically distributed in its both sides to be axially as the criterion by described fixed block 7.
Further, described the first hinge plate 3 has two, is fixedly mounted in same adapter 1 by fixed block 7, and described the second hinge plate 4 has two, is also fixedly mounted in same adapter 1 by fixed block 7.
Further, described angle hinge type expansion joint can be made for metallic material.
The present invention has following beneficial effect: the angle problem on deformation that the invention solves pipeline turning, bend position, the support combinations that simultaneously the present invention carries had both solved hingless angle shape expansion joint and need provide support in addition the problem of frame, also played self spacing effect, even if high temperature has caused the gross distortion of bellows, also needn't worry can exceed its limit of bearing.Simple in structure, practical.
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, take over 2, bellows, 3, the first hinge plate, 4, the second hinge plate, 5, bearing pin, 6, fixed block.
A kind of angle hinge type expansion joint of the present invention, it comprise take over 1, bellows 2, the first hinge plate 3, the second hinge plate 4, bearing pin 5, fixed block 6, the two end axles of described bellows 2 is to connecting described adapter 1, described adapter 1 of every end.On each adapter 1 outer surface, be axially symmetrically welded two fixed blocks 7.Two described the first hinge plates 3 are fixedly connected on two described fixed blocks 7 of same described adapter 1, and two described the second hinge plates 4 are also fixedly connected on two described fixed blocks 7 of same described adapter 1.Between described the first hinge plate 3 and described the second hinge plate 4, connect by bearing pin 5.Form a support combinations by one, two fixed blocks 7 among, described the second hinge plate 4 among described the first hinge plate 3.Described support combinations has two groups, is fixedly connected on the outer surface of the shell ring being formed by described adapter 1 and bellows 2, and is parallel to the axial of shell ring and is symmetrically distributed in its both sides to be axially as the criterion by described fixed block 7.
The present invention can make for metallic material.
Finally explanation is, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, other modifications that those of ordinary skills make technological scheme of the present invention or be equal to replacement, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
