A sealed pipeline elastic penetration vibration isolation device

Abstract

The invention discloses a sealed pipeline elastic cabin-penetrating vibration isolator which comprises a support pipe body, a vibration isolation assembly arranged in the support pipe body, a baffle ring and a ring seal plate, wherein the baffle ring and the ring seal plate are arranged on thetwo sides of the vibration isolation assembly. A welded pipe body is arranged outside the support pipe body in a sleeving way; the outer wall of the welded pipe body is fixedly connected with a bulkhead of a cabin; the vibration isolation assembly is coaxially arranged on a pipeline penetrating through the cabin in a sleeving way; the outer end of the vibration isolation assembly presses against the inner side faceof the baffle ring; the baffle ring is connected with the pipeline; the ring seal plateis arranged on the outer side surface of the baffle ring; the inner circumferential surface of the ring seal plate clings to the outer wall of the pipeline; the inner edge of the ring seal plate is fixedly connected with the baffle ring; and the outer edge of the ring seal plate is connected with the end surface of the support pipe body. The sealed pipeline elastic cabin-penetrating vibration isolator provided by the invention has the beneficial effects that cabin isolation sealed protection can be realized, and a certain self-limiting and displacement compensating ability is realized.

Description

Technical field: [0001] The invention belongs to pipeline vibration and noise control technology in the field of shipbuilding, and in particular relates to a sealed pipeline elastic tank penetrating vibration isolation device. Background technique [0002] Pipeline penetrations are connecting pieces used for pipelines to pass through hull decks, tanks, bulkheads, etc., and to keep the pipelines sealed. In the ship pipeline system, it often happens that the pipeline needs to pass through the bulkhead. In order to maintain the strength, tightness and maintainability of the pipeline, holes are usually welded on the bulkhead to connect the two parts of the bulkhead. end of the pipeline. [0003] When the system pipeline passes through the cabin or hull, it transmits vibration and noise to the hull through the penetrating parts, which is one of the main vibration transmission channels of marine electromechanical equipment. At present, the pipeline penetration of the ship basica...
