Description

Damping elasticity crosses cabin spare

Technical Field

The utility model relates to a technical field that makes an uproar falls in the damping of fluid conveying pipe-line system especially indicates a damping elasticity crosses cabin spare.

Background

At present, when a fluid conveying pipeline of a ship passes through a cabin wall, an internal liquid cabin and other parts, rigid cabin penetrating parts are mostly adopted for connection, mechanical vibration of the pipeline and noise excitation of internal fluid are directly transmitted to a cabin wall and a ship body structure through the rigid cabin penetrating parts, and vibration reduction and noise reduction of the fluid conveying pipeline are extremely disadvantageous. In order to isolate the vibration energy of the pipeline of the fluid conveying system from being directly transmitted to the outside, the development of the damping elastic cabin penetrating piece is necessary.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the damping elastic cabin penetrating piece has the characteristics of adjustable parameters, excellent sealing, good damping effect and the like.

The utility model provides a damping elastic cabin penetration piece, which comprises a flow pipe, a welding ring and an annular air bag; the middle part of the over-flow pipe is provided with a welding ring penetrating through the over-flow pipe, and an annular air bag is arranged between the over-flow pipe and the welding ring; two ends of the annular air bag are respectively fixed with two ends of the welding ring through an outer compression ring, and the middle of the annular air bag is fixed with the welding ring and the overcurrent pipe through an inner compression ring; the weld ring is welded to the bulkhead.

One end of the overflow pipe is connected with the threaded flange through threads, and the other end of the overflow pipe is connected with the welding flange through a welding mode.

And two ends of the welding ring are respectively provided with threads, and the welding ring is in threaded connection with the outer pressure ring.

The overflow pipe and the welding ring are in threaded connection with the inner pressure ring.

A first groove is formed in the joint of the outer pressure ring and the welding ring, and a first sealing ring is arranged in the first groove.

And a second groove is formed at the joint of the overflow pipe and the inner compression ring, and a second sealing ring is arranged in the second groove.

The annular air bag is provided with an inflation connector.

The utility model has the advantages that: firstly, the utility model provides a damping elasticity crossing cabin spare adopts annular gasbag between weld ring and overflow pipe to reach the damping noise reduction effect. Secondly, the utility model discloses a sealing ring sealing connection department, sealing performance is good. Thirdly, the utility model adopts the design of a split mounting structure, is simple and convenient to disassemble and assemble, and can effectively avoid the damage of the welding process to the annular air bag; and the parameters are adjustable, the coating can adapt to different use working conditions, and the coating has good corrosion resistance.

Detailed Description

Referring to fig. 1, the embodiment of the utility model provides a damping elasticity crossing cabin spare, including overflow pipe 8, weld ring 5, annular gasbag 3, threaded connection flange 1 is passed through to 8 one end of overflow pipe, and the other end passes through welding mode and connects welding flange 9. The middle part of the overflow pipe 8 is provided with a welding ring 5 which runs through the overflow pipe 8, an annular air bag 3 is arranged between the overflow pipe 8 and the welding ring 5, and the annular air bag 3 is fixed in position through an inner pressure ring 2 and an outer pressure ring 4. The two ends of the annular air bag 3 are respectively fixed with the two ends of the welding ring 5 through the outer compression ring 4, and the middle of the annular air bag 3 is fixed with the welding ring 5 and the overflowing pipe 8 through the inner compression ring 2. Furthermore, both ends of the welding ring 5 are respectively provided with threads, and the welding ring 5 is in threaded connection with the outer pressure ring 4 so as to position and compress the annular air bag 3; the overflowing pipe 8, the welding ring 5 and the inner compression ring 2 are in threaded connection, the inner wall of the welding ring 5 and the outer wall of the overflowing pipe 8 are in assembly relation with the annular air bag 3, and the whole cabin penetrating piece is installed in a welding mode through the welding ring and the cabin wall. In the technical scheme, the annular air bag 3 plays a role in isolating and dissipating vibration energy, and parameter adjustability is realized by adjusting the air pressure in the air bag. The welding ring 5 is welded to the bulkhead 10.

The junction of outer clamp ring 4, weld ring 5 is equipped with first recess for set up first sealing ring 6, the junction of overflow pipe 8, interior clamping ring 2 is equipped with the second recess, set up second sealing ring 7 in the second recess. The annular air bag 3 is provided with an inflation connector 11 for inflating the air bag.

In the above technical solutions, the above description is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the present invention should be covered by the protection scope of the present invention.
