Abstract
The utility model relates to a pressure-reduction noise-reduction exhaust duct which comprises a transition duct, wherein one end of the transition duct is connected with an exhaust port of a valve body, and the other end of the transition duct is connected with a T-joint; and the T-joint is respectively connected with two silencers through two ducts. The transition duct and T-joint are utilized to reduce the impact of air pressure, and the silencers are utilized for silencing. The impact force borne by the silencers is one half of that of the traditional pressure-reduction noise-reduction exhaust duct, thereby effectively ensuring the connecting reliability of the silencers, reducing the noise, and effectively improving the working environment.
Description
Technical field
The utility model relates to a kind of decompression noise-reducing exhaust pipeline.
Background technique
At present, decompression noise-reducing exhaust pipeline commonly used is directly at the valve body relief opening baffler to be installed, and sees Fig. 2 for details, there are two shortcomings in this exhaust mode: the one,, when valve body switches exhaust, pressure moment reduction, baffler is produced very large impact force, damage easily baffler; The 2nd, because instantaneous pressure drop is very large, produce easily very large noise.These two shortcomings cause this kind decompression noise-reducing exhaust pipeline can not effectively play the function of exhaust and noise reduction.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of baffler, good decompression noise-reducing exhaust pipeline of erasure effect protected.
To achieve these goals, the technical solution of the utility model is: a kind of decompression noise-reducing exhaust pipeline, comprise the transition conduit that an end is connected with the valve body relief opening, the described transition conduit the other end is connected with three-way union, and described three-way union connects two bafflers by two pipelines respectively.
Further, described three-way union is T-shaped three-way union or Y-shaped three-way pipe joint.
Further, described transition conduit length is 1 meter.
Further, described baffler is microperforated panel baffler, impedance complex formula baffler or aperture baffler.
Further, described relief opening is by being spirally connected or being welded to connect transition conduit, and described transition conduit is by being spirally connected or being welded to connect three-way union, and described three-way union is by being spirally connected or being welded to connect pipeline.
The utlity model has following advantage: reduce air pressure by transition conduit and three-way union and impact, the recycling baffler carries out noise reduction, the impact force that baffler bears is half of traditional decompression noise-reducing exhaust pipeline, effectively guarantee the connection reliability of baffler, noise has also reduced simultaneously, effectively improves working environment.
Description of drawings
Fig. 1 is the utility model embodiment's organigram.
Fig. 2 is the prior art organigram.
Among the figure: 1-valve body, 2-transition conduit, 3-three-way union, 4-baffler.
Embodiment
Below in conjunction with drawings and Examples the utility model is further elaborated.
With reference to figure 1, a kind of decompression noise-reducing exhaust pipeline comprises the transition conduit 2 that an end is connected with valve body 1 relief opening, and described transition conduit 2 the other ends are connected with three-way union 3, and described three-way union 3 connects two bafflers 4 by two pipelines respectively.
In the present embodiment, described three-way union 3 is T-shaped three-way union 3 or Y-shaped three-way pipe joint 3.
In the present embodiment, described transition conduit 2 length are 1 meter.
In the present embodiment, described baffler 4 is microperforated panel baffler 4, impedance complex formula baffler 4 or aperture baffler 4.
In the present embodiment, described relief opening is by being spirally connected or being welded to connect transition conduit 2, and described transition conduit 2 is by being spirally connected or being welded to connect three-way union 3, and described three-way union 3 is by being spirally connected or being welded to connect pipeline.
With reference to figure 2, originally technically directly at valve body 1 relief opening baffler 4 is set, the baffler 4 that causes damage and erasure effect poor, than original technology, present embodiment is set up transition conduit 2 and three-way union 3, can effectively alleviate pressure drop and have the gas impact that variation brings, and reduces noise.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
