Embodiment
The utility model embodiment's solution mainly is: the side at the buttress rubber body of anti-vibration rubber is provided with the PVC film; At the array of cylinders layer that the opposite side setting of buttress rubber body is processed by sound-absorbing material, during use, the array of cylinders layer of anti-vibration rubber is close on the pipeline of compressor piping system; The natural frequency of pipeline and compressor staggers; Prevent that both from resonating, reduce noise, and prevent that the anti-vibration rubber fusing from coming off with this.
Please in the lump with reference to Fig. 2～shown in Figure 5; The utility model preferred embodiment proposes a kind of anti-vibration rubber; This anti-vibration rubber is made up of the upper, middle and lower-ranking material, and wherein, the middle level is a buttress rubber body 1; The upper strata is the PVC film (polyvinyl chloride film) 2 that is arranged on a side of buttress rubber body 1, and lower floor is the array of cylinders layer 3 that is arranged on the opposite side of buttress rubber body 1.In use, the lower floor with anti-vibration rubber is that array of cylinders layer 3 is close on the pipeline of compressor piping system.
Particularly, buttress rubber body 1 adopts not the isobutyl rubber material of sulfur-bearing to process in the present embodiment, why adopts the not isobutyl rubber material of sulfur-bearing, is because sulphur has corrosive action to copper pipe.
Isobutyl rubber material is a kind of sound-absorbing material, can effectively weaken the sound wave of each frequency range, thereby has noise reduction preferably.
Wherein, the thickness of buttress rubber body 1 can be set to 3mm～10mm.
The PVC film 2 that is positioned at buttress rubber body 1 upper strata is used to protect buttress rubber body 1, because buttress rubber has certain viscosity, PVC film 2 is sticked on the buttress rubber body 1, can prevent that buttress rubber body 1 is stained with other foreign material.
