The utility model discloses a long-distance pipeline sound-insulation and vibration-isolation facility, which overcomes the defects that the present long-distance pipeline has a poorer vibration isolation effect and larger noise even adopting fiber sound-absorbing material for wrapping. According to the long-distance pipeline sound-insulation and vibration-isolation facility, the outer wall of a long-distance pipeline is wrapped in a high-polymer damping layer, fiber sound-absorbing layers and sound-insulation layers; and the high-polymer damping layer is painted on the outer wall. The embodiment of the utility model adopts an elastic support for the long-distance pipeline, paints the damping material, and performs sound insulation and wrapping on the outer wall, so as to greatly reduce pipeline noise.
Description
Technical field
The utility model relates to a kind of long distance pipeline sound insulation vibration isolation facility.
Background technique
Can produce noise when transmitting in pipeline for pressurized gas, opacity technique commonly used is mainly adopt the technique for packing of fiber sound-absorbing material or do not wrap up at present.These technology generally can obtain certain soundproof effect, but for vibration isolation, effect is unsatisfactory.Therefore the noise that causes due to vibration still can't be avoided.In addition, general long distance pipeline all adopts rigid support, can't reduce the intrinsic vibration frequency of pipeline, also is difficult to further reduce noise.
The model utility content
Technical problem to be solved in the utility model is that to overcome present long distance pipeline vibration isolating effect relatively poor and adopt fiber sound-absorbing material parcel still to have the defective of larger noise.
In order to solve the problems of the technologies described above, the utility model provides a kind of long distance pipeline sound insulation vibration isolation facility, and described facility comprises macromolecule damping layer, fiber absorbent treatment and the Sound insulating layer that is wrapped on described long distance pipeline outer wall.
Preferably, the brushing of described macromolecule damping layer is on described long distance pipeline outer wall.
Preferably, be enclosed with the described macromolecule damping layer of one deck, two-layer described fiber absorbent treatment and two-layer described Sound insulating layer on described long distance pipeline outer wall.
Preferably, wrap up successively from inside to outside described macromolecule damping layer, the first fiber absorbent treatment, the first Sound insulating layer, the second fiber absorbent treatment and the second Sound insulating layer on described long distance pipeline outer wall.
Preferably, described facility comprises the elastic support that supports described long distance pipeline.
Compared with prior art, embodiment of the present utility model adopts yielding support to long distance pipeline, the brushing damping material, and at outer wall sound insulation parcel, can greatly reduce duct noise.Embodiment of the present utility model is applicable to control long distance pipeline due to the noise of generation of vibration.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment's long distance pipeline sound insulation vibration isolation facility.
Embodiment
Describe mode of execution of the present utility model in detail below with reference to drawings and Examples, how the application technology means solve technical problem to the utility model whereby, and the implementation procedure of reaching technique effect can fully understand and implement according to this.Each feature in the utility model embodiment and embodiment, mutually combining under the prerequisite of not conflicting mutually is all within protection domain of the present utility model.
The noise that produces when pressurized gas transmit in pipeline, the origin cause of formation are mainly that the turbulent flow that forms in the gas flow process makes the tube wall vibration, vibrate outside radiation formation noise.This effect is called as " pneumatic hammer effect " as hammer knocks pipeline.
Turbulent flow is mainly that the irregularity in the gas flow process, the turbulent flow that occurs when passing through bend pipe and valve etc. are located the factors such as throttling of gas are caused.In pipeline, air-flow velocity is faster, and gas pressure is larger, and bend pipe is more, and valve throttle is mandatory stronger, and the pneumatic hammer effect is more serious.
The pneumatic hammer effect is more serious, and the rigidity at pipeline support place is stronger, and the vibration of pipeline is just stronger, and the noise of radiation is just larger.
The utility model embodiment's long distance pipeline sound insulation vibration isolation facility comprises the macromolecule damping layer, fiber absorbent treatment and the Sound insulating layer that are wrapped on the long distance pipeline outer wall.Wherein, the brushing of macromolecule damping layer is on the outer wall of long distance pipeline.In embodiment of the present utility model, be enclosed with one deck macromolecule damping layer, two-layer fiber absorbent treatment and two-layer Sound insulating layer on outer wall.
As shown in Figure 1, in embodiment of the present utility model, be enclosed with successively from inside to outside macromolecule damping layer 1, the first fiber absorbent treatment 21, the first Sound insulating layer 31, the second fiber absorbent treatment 22 and the second Sound insulating layer 32 on the outer wall 9 of long distance pipeline.In embodiment of the present utility model, what Sound insulating layer adopted is sheet metal.
Embodiments of the invention also comprise the elastic support that supports long distance pipeline, and this yielding support can further reduce the noise that causes due to pipe vibration.
In embodiment of the present utility model, the composite structure fissipation factor of macromolecule damping layer, the density of fiber sound-absorbing material, acoustic absorptivity, the parameters such as the thickness of sound insulating material, material, according to noise spectrum, the sound level at scene, and the condition such as needed noise insulation factor, scene temperature, humidity and selecting.
Embodiment of the present utility model is the brushing damping material on long distance pipeline, weakens the Oscillation Amplitude of pipeline, has reduced to a certain extent the noise of pipeline.Embodiment of the present utility model adopts elastic support with long distance pipeline, reduces the eigentone of pipeline, has reduced to a certain extent the noise of pipeline.Embodiment of the present utility model reduces pipe vibration to extraradial intensity to a certain extent by the long distance pipeline parcel that insulates against sound, and effectively prevents noise radiation, has reduced to a certain extent the noise of pipeline.
Although the disclosed mode of execution of the utility model as above, the mode of execution that described content only adopts for ease of understanding the utility model is not to limit the utility model.Those of skill in the art under any the utility model; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can carry out any modification and variation on the form of implementing and details; but scope of patent protection of the present utility model still must be as the criterion with the scope that appending claims was defined.
