Background technology
In Control Technique of Vibration and Noise field, pipeline vibration and vibration isolating method have obtained more and more concerns.
In addition to the technological means such as application vibration absorbing hose, elastomer connector, substituting conventional rigid stent using vibration isolation stent is
The important technology approach of vibration isolation of pipeline.The vibration isolation of pipeline stent of current practice is mostly single-layer partiting polarization, using rubber shock absorber
Or rubber pad realizes vibration isolation, but in order to ensure to impact security, the rigidity of rubber shock absorber or rubber pad is typically much higher than vibration isolation
Demand, causes vibration isolating effect unsatisfactory；To pursue vibration isolating effect, there is part pipeline support to employ double-layer vibration isolating, but make
After two layers of vibration isolator, structure type is relatively complicated, and in addition to ensure the installation space of vibration isolator, the size of pipeline support is led to
It is often larger, arrange that position intensive, that space is nervous is difficult to lay in pipeline.
Therefore, one kind is objectively needed to have efficient vibration isolation and shock resistance, and simpler compact vibration isolation of pipeline concurrently
Stent.At present, pipeline support both domestic and external can not meet above multiple function demand.
Utility model content
In view of this, the utility model provide one kind can spacing gasbag-type vibration isolation of pipeline stent, pipeline can be effectively improved
The vibration isolating effect of stent, while there is limit function in the case where impacting operating mode, meet security, reliability requirements, and structure
It is compact, occupy little space, adjustment it is convenient for disassembly and assembly.
One kind can spacing gasbag-type vibration isolation of pipeline stent, which includes upper element, lower component and base, it is described on
Parts and lower component are semicircular configuration, and upper element includes upper support ring, upper half annular air-pocket and upper snap ring, upper half
Vulcanization connects upper snap ring and upper support ring respectively inside and outside annular air-pocket；Lower component includes lower snap ring, lower semi-circular gas
Capsule and lower support ring, the lower snap ring of vulcanization connection and lower support ring respectively inside and outside lower half annular air-pocket, upper element and under
Parts are fixed by upper support ring and lower support ring by fastening bolt, and lower support ring is fixedly connected with base, upper half annular gas
Inflation valve nozzle is equipped with capsule and lower half annular air-pocket.
Further, the upper half annular air-pocket and lower half annular air-pocket are semicircle ring type airbag structure, its intrinsic frequency
Determined with performance parameters such as bearing capacitys according to the vibration isolating effect requirement under different loads environment.
Further, the air pressure inside of the upper half annular air-pocket, lower half annular air-pocket by inflating valve nozzle adjusting and
Control.
Further, the upper snap ring and lower snap ring are convex section, and upper support ring and lower support ring are concave section, recessed
Convex cross section structure is used cooperatively the function of realizing position limitation protection.
Further, the mounting hole processed in the mounting seat is slot hole.
Beneficial effect：
1st, the utility model uses air bag Vibration Absorbing System Design, by rationally controlling the inner gas pressure of air bag, controls its intrinsic frequency
Rate is far below traditional rubber shock absorber, and vibration isolating effect is more superior than traditional vibration isolation stent.
2nd, the utility model is using upper and lower snap ring and the Combination Design of upper and lower support ring concavo-convex cross-section structure type, pipeline
Vibration isolation stent can provide effective position limitation protection in the case where impacting operating mode, enhance the impact resistance of structure.
3rd, mounting hole of the utility model in mounting seat is both designed as slot hole, and making it, part can in installation process
Adjust, make the site error that the utility model arranges pipeline that there is stronger adaptability.
4th, the utility model is compact-sized, occupies little space, and dismounts flexibly, easy to maintain, and it is first-class to be particularly suitable for naval vessels
Narrow and small installation space.
