As shown in Figure 1 to Figure 3：A kind of fluid pressure line with vibration-damping function joint through walls, including：Pipeline connector 1, axle
To free degree shock absorber 2, ring free degree shock absorber 3, bushing 4, wallboard connector 5 and baffle plate 6；
Wallboard connector 5 is left and right symmetrically arranged forms annular cavity in the both sides of wallboard 7；
Pipeline connector 1 passes through annular cavity, and its both ends is connected with fluid pressure line respectively；
Pipeline connector 1 positioned at annular cavity part is socketed with axial freedom shock absorber 2 and baffle plate 6, axially free
Degree shock absorber 2 is limited on the inwall of wallboard connector 5 by the baffle plate 6 at its both ends；
Bushing 4 is provided between axial freedom shock absorber 2 and ring free degree shock absorber 3, the both ends of the inner chamber of bushing 4 are set
Being equipped with can be along its baffle plate 6 in axial sliding；
The outer wall of ring free degree shock absorber 3 abuts with annular cavity, when high-pressure pulsating liquid is by pipeline connector 1
Wait, pipeline connector 1 realizes multi-direction vibration-damping function by axial freedom shock absorber 2, ring free degree shock absorber 3.
In the present embodiment, wallboard connector 5 is designed to that a wallboard connector is designed to the structure of a similar flange, method
Blue inner chamber carries certain space, for accommodating internal structure and fixed structure, supports axial freedom damper and ring free
Spend damper；
Flange periphery carries four mounting holes 51 for being used for being fixed on wallboard 7；Wallboard connector is in the both sides of wallboard
One is each provided with, the wallboard connector 5 for being distributed on the both sides of wallboard 7 is fixed on wallboard 7 jointly by mounting hole 51.
Wallboard connector 5 is provided with medium pore 52, and wallboard connector 5 is passed through for pipeline connector 1；
Medium pore 52 is more than the external diameter of the jointing 12 of pipeline connector, while is not more than and gives ring free degree damper
The spatial joint clearance that 2 bobs reserve, pipeline connector 1 is prevented to be stuck on wallboard connector 5.
As shown in Figure 4：The both ends of pipeline connector 1 carry standard pipe joint 12 in the present embodiment, be easy to and its
He is used cooperatively pipeline jointing construction；Pipeline connector is also the part that liquid passes through, so being hollow structure；Simultaneously for
Axial freedom shock absorber is used cooperatively, and center is provided with center projections 11 on the pipeline connector diameter of axle, and center projections 11 are set
There is the symmetrical installation conical surface 13, the installation conical surface 13 matches with axial freedom shock absorber, is equal to axial freedom and subtracts
Shake device outer toroid the conical surface size of inner conical surface 21.
As shown in Figures 5 and 6：Axial freedom shock absorber 2 is by multiple outer toroids 21 with inner conical surface in the present embodiment
Formed with multiple interior annulars 22 with male cone (strobilus masculinus)；
Outer toroid 21 and interior annular 22 are symmetrical set along center projections 11；Outer toroid 21 and interior annular 22 pass through the conical surface
It is connected integral, one end is coordinated by the inner conical surface of outer toroid 21 with the installation conical surface 13, and the other end is connected on baffle plate 6.
After axial freedom shock absorber 2 bears the axial force of the installation transmission of the conical surface 13 of pipeline connector 1, outer toroid 21
And the restoring force of the elastic deformation of interior annular 22 plays resilient support effect to moving axially relative；Due to outer toroid 21 and inner circle
For ring 22 along when coordinating that the conical surface is relative to be slided, contact surface has very big frictional force, during stand under load, axial force by surface pressing with rub
Dynamic balance is wiped to offset.
It is appreciated that：In the present embodiment, the axial length of axial freedom shock absorber 2 and the depth of annular cavity are matched somebody with somebody
Close, ensure that interior annular 22 and outer toroid 21 conical surface in the case of not stand under load do not produce separation.
As shown in Figure 7：Ring free degree shock absorber 3 is combined into by multilayer corrugated plate by the vulcanization of rubber in the present embodiment
Circular ring structure；
Its external diameter is less than the internal diameter of wallboard connector 5, ensures that ring free degree shock absorber 3 can be placed in wallboard connector 5
It is interior；The external diameter of its internal diameter and bushing 4 is interference fitted, and ensures bushing 4 and the ring power transmission effect of ring free degree shock absorber 3, is improved
Ring damping property.
In the present embodiment, installation bushing 4 is for power between ring free degree damper 3 and axial freedom shock absorber 2
Uniformly transfer；The external diameter of bushing 4 is interference fitted with the internal diameter of ring free degree damper 3, bushing 4 and axial freedom damping
It is slidably matched between device 2；After wallboard connector 5 is connected on wallboard 7, it is appropriate to be left between the both ends of annular cavity and bushing 4
Gap.
Present apparatus installation order is as follows：Ring free degree shock absorber 3 is initially charged with wallboard connector 5, then by bushing 4
It is pressed into ring free degree damper 3；The interior annular 22 of axial freedom damper 2 and outer toroid 21 are sequentially sleeved in pipeline connection
On device 1, both ends baffle plate 6 blocks, and baffle plate 6 abuts with the inwall of wallboard connector 5.
Baffle plate 6 and the apertures of pipeline connector 1, can slide axially, the external diameter of baffle plate 6 and axial freedom damper 2
Outer toroid external diameter it is identical, and in the bushing 4, and can be slided along bushing 4.Baffle plate 6 is to prevent pipeline connector 1 in
The swing of the heart provides support stiffness.
Pipeline connector 1 and axial freedom damper 2 and baffle plate 6 are put into a sidewall paneling connector 1 again, then use spiral shell
Tether and connect another sidewall paneling connector 5.
The present invention is coordinated with other attachment structures by pipeline connector 1 and is connected with high-pressure and hydraulic pipeline, is connected by wallboard
Device 5 is connect with wallboard 7 to be connected.Connected in the interior annular and outer toroid of the both sides of wallboard 7 arrangement axial freedom damper, and in wallboard
Under the restriction effect of device 5, in the case where there is axial impact loading effect, axial freedom damper stand under load, each inside and outside annulus is along circular cone
Face relative motion produces elastic deformation and plays spring effect, is slided because outer toroid is relative with interior annular edge cooperation circular cone, contact
Surface consumes the destructiveness that part impact energy reduces impulse load during having very big frictional force, loading and unloading.
Ring free degree damper is installed in the periphery of axial freedom damper, when producing radial load, ring is certainly
By degree damper by the load transmitted, and it is deformed under the collective effect of wallboard connector support reaction, alleviates impact, subtract
Side crops industry is to structural damage.
It is last it is to be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent
The present invention is described in detail with reference to the foregoing embodiments for pipe, it will be understood by those within the art that：It is still
Technical scheme described in foregoing embodiments can be modified, or which part technical characteristic is equally replaced
Change；And these modifications or replacement, the essence of appropriate technical solution is departed from the essence of various embodiments of the present invention technical scheme
God and scope.
