Abstract
The utility model belongs to the technical field of the pipeline compensation, a expansion joint with elasticity suspension damping structure is proposed. An expansion joint with elasticity suspension damping structure who provides is including end pipe (1) and bellows (6), the outside of bellows (6) is provided with pull rod (5), pull rod (5) for many of setting up along the bellows circumference, its characterized in that: the both ends of every pull rod (5) are connected with spring (3) respectively, spring (3) set up in sealed sleeve pipe (2) to can stretch out and draw back in sealed sleeve pipe (2), sealed sleeve pipe (2) are connected with end pipe (1) that corresponds through load lug (8), the both ends of pull rod (5) are connected with spacing ring (7) respectively.
Description
Technical field
The utility model belongs to compensation of pipeline technical field, is specifically related to a kind of expansion joint with elastic suspension vibration damping structure.
Background technique
Pipeline needs design compensation device to compensate expanding with heat and contract with cold of pipeline in running, to reduce pipe stress, ensures the safe operation of pipe-line system; There is power equipment in pipeline, it can produce vibration in running, is delivered to other equipment be attached thereto by pipeline, causes other equipment premature failure simultaneously.And violent vibration also can cause the fatigue failure of bellows to destroy, produce to normal safe and work the mischief.
Corrugated expansion joint, in a large number for various pipe network, has varied matured product structure to meet the compensation demand of pipeline.The compensator of existing selection for pipeline mainly stresses compensate function, and less for the concern of vibration and noise reducing aspect.Vibration Absorption Designing not only will be considered to reduce the vibration source of power equipment own, also needs vibration damping structure reasonable in design, reduces the energy in vibration passing process.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model proposes a kind of expansion joint with elastic suspension vibration damping structure.
The utility model adopts following technological scheme for completing above-mentioned purpose:
With an expansion joint for elastic suspension vibration damping structure, described expansion joint includes end pipe and is welded on the bellows between adjacent two end pipes; The arranged outside of described bellows has pull bar, and described pull bar is many that arrange along bellows circumference, and described in every root, the two ends of pull bar are connected to spring; Described spring is arranged in Sealed casing pipe, and can at stuffing box gland inner telescoping tube; Described Sealed casing pipe is connected with corresponding end pipe by load lug, makes two of welded bellows two ends to hold pipe to be connected as one by spring, forms the elastic suspension vibration damping structure in order to cut down the vibration of bellows; The two ends of described pull bar are connected to the limited ring preventing bellows carry from moving.
Sealed casing pipe is stretched into respectively in the two ends of pull bar, has ball taper faced washer in the linkage section arranged outside of Sealed casing pipe and pull bar, in order to meet the needs that expansion joint lateral displacement compensates.
A kind of expansion joint with elastic suspension vibration damping structure that the utility model proposes, elastic suspension vibration damping structure adopts double-spring structure, is conducive to cutting down pipeline and is delivered to vibration on bellows, reach good effectiveness in vibration suppression; Expansion joint is provided with limit structure, and limit structure can protect bellows, avoids carry to move destruction; With ball taper faced washer on pull bar, pipeline lateral displacement can be compensated; Not only ensure that line temperature compensates requirement, but also meet the vibration damping demand of bellows.

Embodiment
With specific embodiment, the utility model is illustrated by reference to the accompanying drawings:
As shown in Figure 1, a kind of expansion joint with elastic suspension vibration damping structure, described expansion joint includes end pipe 1 and is welded on the bellows 6 between adjacent two end pipes; The arranged outside of described bellows 6 has pull bar 5, and described pull bar 5 is many that arrange along bellows circumference, and described in every root, the two ends of pull bar 5 are connected to spring 3; Described spring 3 is arranged in Sealed casing pipe 2, and can stretch in Sealed casing pipe 2; Described Sealed casing pipe 2 is connected with corresponding end pipe 1 by load lug 8, makes two of welded bellows two ends to hold pipe to be connected as one by spring, forms the elastic suspension vibration damping structure in order to cut down the vibration of bellows; When bellows vibrates, the spring in Sealed casing pipe stretches thereupon, can effectively absorb and discharge vibrational energy like this, reach good effectiveness in vibration suppression; The two ends of described pull bar 5 are connected to the limited ring 7 preventing bellows carry from moving, and can prevent bellows carry from moving, play a protective role; Sealed casing pipe is stretched into respectively in the two ends of pull bar, has ball taper faced washer in the linkage section arranged outside of Sealed casing pipe and pull bar, in order to meet the needs that expansion joint lateral displacement compensates.During in-site installation, expansion joint end pipe docks with adjacent channel and welds.
