The high-pressure pipeline is provided with the vibration attenuation device, according to the vibration attenuation device, the pipeline is allowed to vibrate to produce a shift so as to release the vibration of the pipeline, after the vibration, the pipeline can be enabled to freely restore into an initial state by the spring inside the vibration attenuation device, and meanwhile the vibration is isolated. By the adoption of the vibration attenuation device, the problem of vibration of the high-pressure pipeline can be improved, the operation quality of equipment is improved, and the vibration attenuation device has extremely high application value.

Description

High pressure pipe line and vibration damping equipment thereof
Technical field
The present invention relates to damping technology, particularly a kind of vibration damping equipment of high pressure pipe line.
Background technique
Present high-pressure and hydraulic pipeline, particularly large-scale hydraulic press, such as extrusion press, the hydraulic tubing of the equipment such as forging press, because pressure is higher, the pressure jump meeting causes more mechanical vibration.If caused vibration can not be eliminated, can conduct to from vibration source other positions of equipment, cause equipment when operation, to produce larger vibration and noise, long-term periodic vibration meeting has very large harm to the operation of equipment, as causing the loosening of fastener nut or screw, the damages of pipeline or flange Sealing etc. can have influence on the normal operation of equipment, even can cause fire, personal injury etc.
Summary of the invention
In view of the problems referred to above of the prior art, the invention provides a kind of high pressure pipe line and vibration damping equipment thereof.
The invention provides a kind of vibration damping equipment of high pressure pipe line, comprising: recessed flange (1), boss flange (5), bolt (2), nut (4) and spring (3);
Described recessed flange (1) and boss flange (5) are fixed by bolt (2) and nut (4), are provided with spring (3) between described boss flange (1) and the recessed flange (5), and described bolt (2) passes this spring (3).
Described recessed flange (1) is provided with Sealing (6) with the joint of boss flange (5) inside.
In the inside of described recessed flange (1), be provided with seal groove with the joint of described boss flange (5), be provided with seal ring in the described seal groove.
Described spring (3) has certain pre compressed magnitude between described recessed flange (1) and boss flange (5).
The present invention also provides a kind of high pressure pipe line, comprises a plurality of subtubes and above-mentioned vibration damping equipment, adopts this vibration damping equipment to connect between each subtube.
High pressure pipe line of the present invention is equipped with vibration damping equipment, and allow pipe vibration to produce the vibration that displacement discharges pipeline by this vibration damping equipment, after vibration finished, the spring of vibration damping equipment inside can guarantee that pipeline can freely reply original state, cut off simultaneously vibration and can not conduct to follow-up pipeline.Therefore can improve the vibration problem of high pressure pipe line, improve the equipment ride quality, have very high using value.
Description of drawings
Figure 1 shows that the application scenarios schematic representation of high pressure pipe line of the present invention;
Figure 2 shows that the partial enlarged drawing of the vibration damping equipment among Fig. 1;
Figure 3 shows that the partial enlarged drawing at the Sealing place among Fig. 2;
Figure 4 shows that the mechanical model schematic representation of high pressure pipe line of the present invention.
Embodiment
The exemplary embodiments that embodies feature ﹠ benefits of the present invention will be described in detail in the following description.Be understood that the present invention can have in different embodiments various variations, its neither departing from the scope of the present invention, and explanation wherein and appended accompanying drawing be when the usefulness that explain in itself, but not in order to limit the present invention.
Referring to the application scenarios schematic representation that Figure 1 shows that high pressure pipe line of the present invention, Figure 2 shows that the partial enlarged drawing of the vibration damping equipment among Fig. 1, Figure 3 shows that the partial enlarged drawing at the Sealing place among Fig. 2.Below in conjunction with Fig. 1-Fig. 3 the present invention is carried out specific description.
High pressure pipe line of the present invention is connected and composed by a plurality of subtubes and a plurality of isolation mounting, uses vibration damping equipment to connect between each subtube, cushions vibration between each pipeline by this vibration damping equipment, to play the purpose to the high pressure pipe line protection.
As shown in the figure, vibration damping equipment of the present invention is comprised of recessed flange 1, boss flange 5, bolt 2, nut 4, spring 3 and Sealing 6.
Wherein, recessed flange 1 and boss flange 5 are fixed together by bolt 2 and nut 4, and an end of recessed flange 1 and boss flange 5 interconnects, and the other end is provided with the groove of welded pipe line, in order to connect subtube; Be provided with spring 3 between recessed flange 1 and boss flange 5, bolt 2 has passed spring 3, and spring 3 is provided with certain pre compressed magnitude to strengthen effectiveness in vibration suppression.
The joint of recessed flange 1 and boss flange 5 inside is provided with Sealing 6, so that does not tightly leak the joint.As shown in Figure 3, inside in recessed flange 1, the joint of itself and boss flange 5 is provided with seal groove, lay seal ring in the seal groove, in the outside of boss flange 5, the joint of itself and recessed flange 1 is for being used for column sealed of sealing, the linkage structure that recessed flange 1 is above-mentioned with the employing of boss flange 5, by the sealing of seal ring, so that does not tightly leak the joint.Those skilled in the art expect that easily the joint of recessed flange 1 and boss flange 5 inside also can adopt other forms of Sealing, and it does not affect technical purpose of the present invention and beneficial effect.
Schematic representation referring to the mechanical model that Figure 4 shows that this high pressure pipe line, the working principle of this high pressure pipe line is as follows: when the pipeline vibration-generating, drive boss flange 1 or recessed flange 5, when two flanges have one or two all to produce vibration, the stressed generation axial displacement of steel pipe in the pipeline that flange links to each other, flange can passively cause corresponding displacement simultaneously, the displacement that produces will discharge the vibration of pipeline, compress simultaneously the spring 3 between the convex-concave flange, be to flexibly connect between the flange, so two flange institute connecting leg road vibration mutual noninterferences, vibration can not conducted mutually yet, simultaneously because the effect of Sealing 6 is arranged, the high pressure oil of pipe interior can not leak, and when the vibration end, spring 3 compressions recover, the pipeline attitude that also restores to the original state, thus realized cushioning effect.
High pressure pipe line of the present invention has been installed vibration damping equipment, allows pipe vibration to produce the vibration that displacement discharges pipeline by this vibration damping equipment, and after vibration finished, the spring of vibration damping equipment inside can guarantee that pipeline can freely reply original state, cuts off simultaneously vibration.Therefore, after the pressure generation sudden change of high pressure pipe line internal cause hydraulic oil caused that pipe vibration or the passive generation mechanical vibration of pipeline reach this damping device, vibration will be cut off, and can not reach follow-up connecting tube.Adopt this vibration damping equipment can improve greatly the vibration problem of high pressure pipe line, the vibration that machinery or hydraulic pressure cause is eliminated effectively, improve the equipment ride quality, can be applied in the pipeline of hydraulic equipment, have very high using value.
Those skilled in the art should recognize change and the retouching of doing in the situation that does not break away from the scope and spirit of the present invention that the appended claim of the present invention discloses, all belong within the protection domain of claim of the present invention.
