Low-rigidity elastic penetration pipe fitting

Abstract

The invention discloses a low-rigidity elastic cabin penetrating pipe fitting, and the pipe fitting comprises a supporting assembly and an inflatable polymer bag body assembly; the supporting assemblycomprises a supporting ring fixed to a cabin wall open hole and two first fastening ferrules arranged at the two sides of the supporting ring in a sleeving mode; the inflatable polymer bag assembly comprises a pipe body with flanges or connectors at the two ends and a bag body main body arranged at the outer side of the pipe body in a sleeving mode; the interior of the bag main body is hollow tocontain gas, an inflation hole communicated with a hollow cavity in the bag main body is formed in the bag main body, the supporting ring is arranged at the outer side of the bag main body in a sleeving mode and seals the hollow cavity of the bag main body, and the two sides of the bag main body are connected with first fastening ferrules through fasteners. According to the low-rigidity elastic cabin penetrating pipe fitting, the damping effect of a pipe at a cabin penetrating position can be improved.

Description

technical field [0001] The invention relates to the technical field of vibration and noise control of pipelines in auxiliary machinery systems, in particular to a low-rigidity elastic through-cabin pipe fitting. Background technique [0002] At present, two ways are used for the passage of the ship's pipeline, one is the rigid passage, and the other is the elastic passage. Rigid tank passages are rigidly connected to the bulkhead by the pipeline through the tank, and the vibration of the pipeline can be directly transmitted to the bulkhead, which is not conducive to the electrical insulation of the pipeline and the hull structure. A layer of vibration-damping rubber is vulcanized between the welded backing plate of the bulkhead and the pipeline in the existing elastic through-cabin parts. Although the electrical insulation between the pipeline and the hull structure is better solved, the elastic through-cabin of this structure The rigidity of the parts is relatively large, ...

AI Technical Summary

Problems solved by technology

A layer of vibration-damping rubber is vulcanized between the welded backing plate of the bulkhead and the pipeline in the existing elastic through-cabin parts. Although the electrical insulation between the pipeline and the hull structure is better solved, the elastic through-cabin of this structure The rigidity of the parts is relatively large, and the vibration damping effect is not ideal

[0003] The vibration control of the pipeline system is the difficulty and focus of the mechanical noise control of low-noise ships at present. Since the pipelines have generally adopted elastic horse feet with good vibration isolation effect for vibration isolation, the active rigid tank parts and the elastic tank with high rigidity Parts have become one of the short boards in the mechanical noise control of low-noise ships, and there is an urgent need for a low-rigidity elastic through-cabin part to solve the vibration reduction problem of the pipeline through-cabin parts
