A kind of sound-absorbing and anti-vibration tank pipe fitting for deck and its installation method

Abstract

The invention discloses a deck silencing and anti-vibration bulkhead penetration pipe piece and an installation method thereof. Two sides of the deck are covered with webs respectively, hollow silencing pipes are arranged between the two webs, a first screw is arranged at each end of each silencing pipe, the first screws at two ends of the silencing pipes penetrate the two webs respectively, and the first screws outside the webs are provided with first nuts for fixing; a plurality of silencing ports are formed in the sides, facing a sleeve, of the silencing pipes. Compared with the prior art,the deck silencing and anti-vibration bulkhead penetration pipe piece and the installation method thereof have the advantages that silencing and anti-vibration effects are achieved, influence of noise on crew work and loosening and cracking of pipe piece weld points due to long-term vibration can be avoided, and noise concealment and life comfort of ships are improved.

Description

technical field [0001] The invention relates to a deck sound-absorbing and anti-vibration pipe fitting and an installation method thereof, belonging to the technical field of marine accessories. Background technique [0002] With the development of the shipbuilding industry and the improvement of ship comfort requirements, the existing engineering ships, especially the ships that must meet the requirements of the ILO International Labor Organization, have a certain impact on the comfort of the working environment of the crew on board, such as vibration, noise, and illuminance. Further requirements. For example, engineering ships with the "HAB" classification symbol have higher requirements for noise and vibration. How to reduce the excessive vibration and noise generated by the cabin parts of the ship's vibration source piping system (such as: hydraulic piping system, compressed air piping system, cooling water piping system, etc.) has become an urgent problem to be solved....

AI Technical Summary

Problems solved by technology

[0003] At present, the shock absorption and noise reduction method of the existing pipeline through the cabin is to add a rubber expansion joint at both ends of the conventional web or casing passing through the cabin. The noise reduction effect does not meet the requirements of the specification, and it is not necessary to use it when encountering chemical tankers. The versatility of this device is not high, and it is difficult to meet the requirements of fire separation

[0004] When the fluid medium needs to be transported through the pipeline, the fluid medium will vibrate the pipeline used to transport the fluid medium due to the change of the load or the pressure fluctuation of the fluid medium. All adopt rigid connection, which makes the vibration of the pipeline directly spread to the offshore platform and ship, causing serious vibration to the offshore platform and ship as a whole, thus affecting the normal operation of the offshore platform and ship

[0005] The physical properties and welding performance of the tank-through pipe fittings in the prior art are poor, resulting in short service life, general sealing performance, and large vibration and noise, which cannot meet the concealment function requirements of new ships
