Abstract
The invention discloses a silencing pipe of a ventilation system, which is characterized by adopting the shape of a loop and comprising at least one electric valve therein. Therefore, the wind velocity and ventilation quantity of the silencing pipe can be controlled or regulated as per actual test requirements.
Description
Technical field
The present invention relates to the silencing pipeline of a kind of ventilating system in the acoustical testing environment.
Background technology
In the acoustical testing environment, some test need have certain requirement to environment temperature, therefore needs to adopt air conditioner ventilating system.Therefore but ventilating system is easy to generate noise, silencing pipeline need be set sometimes eliminate or reduce noise.
Usually, the material of silencing pipeline is the outside steel plate that adopts, the inner perforated plate that adopts, the middle acoustical cotton of filling.When ventilating, can sound of the wind and external noise be absorbed through the microcellular structure of material itself on the one hand, also can come controlled wind speed on the other hand, to reach the purpose of the sound that reduces wind through the length of silencing pipeline.
Yet existing silencing pipeline is generally linear pattern, and it can not control or regulate wind speed and air quantity according to the test needs.
Summary of the invention
The objective of the invention is to provides a kind of silencing pipeline of ventilating system to above-mentioned defective of the prior art, and it can control or regulate the size of wind speed and air quantity.
For realizing the foregoing invention purpose, the present invention has adopted following technical scheme: a kind of silencing pipeline of ventilating system is characterized in that it is shaped as the winding formula, and comprises at least one electrically operated valve of the portion of setting within it.
In addition, the present invention also proposes following attached technical scheme:
Said at least one electrically operated valve comprises first electrically operated valve, second electrically operated valve and the 3rd electrically operated valve.
Said silencing pipeline also comprises first ventilating path and second ventilating path.
Said first electrically operated valve and the 3rd electrically operated valve are positioned on first ventilating path.
Said second electrically operated valve is positioned on second ventilating path.
Than prior art, the invention has the advantages that: the silencing pipeline of ventilating system is designed to the winding formula, and portion is provided with electrically operated valve within it, controls or regulate the wind speed of silencing pipeline and the size of ventilation according to the test needs of reality with this.
Description of drawings
Fig. 1 is the floor map corresponding to the silencing pipeline of the ventilating system of preferred embodiment of the present invention.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical scheme of the present invention is done further nonrestrictive detailed description.
With reference to Fig. 1, a kind of silencing pipeline 1 that is applied to the ventilating system in the acoustical testing environment, its material is the outside steel plate that adopts, the inner perforated plate that adopts, the middle acoustical cotton of filling; Like this, when ventilating, this silencing pipeline 1 can absorb sound of the wind and external noise through the microcellular structure of material itself.
On the other hand, the shape of this silencing pipeline 1 is set to the winding formula, comprises air inlet 12 and air outlet 14 and first, second ventilating path 16,18 between air inlet 12 and air outlet 14.This first, second ventilating path 16,18 is respectively the longest ventilating path and the shortest ventilating path of silencing pipeline 1.Above-mentioned silencing pipeline 1 comprises that also at least one electrically operated valve of the portion of setting within it is to regulate air quantity; Said at least one electrically operated valve comprises first electrically operated valve 11, second electrically operated valve 13 and the 3rd electrically operated valve 15; Wherein the first, the 3rd electrically operated valve 11,15 is positioned on first ventilating path 16; And second electrically operated valve is positioned on second ventilating path 18; Those electrically operated valves are prior art, and it can be rotated adjusting at 0 ° respectively between 90 °, thereby change the size of its ventilation.Therefore; When the test environment inside of reality needs to increase wind speed and strengthens ventilation, can close the first, the 3rd electrically operated valve 11,15 simultaneously, and open second electrically operated valve 13 fully; Obtain the second the shortest ventilating path 18 with this, thereby reach maximum wind velocity and Maximum Ventilatory Volume; And when the actual minimum ventilation of test environment inside needs when reaching best quiet effect, can all electrically operated valves 11,13 and 15 Close Alls be made that silencing pipeline 1 is stuffy; And when actual test environment inside needs less wind speed; Can open the first, the 3rd electrically operated valve 11,15 simultaneously; And close second electrically operated valve 13; Obtain the first the longest ventilating path 16 with this, reduce noise with the flow velocity that reduces wind, and can regulate the size that the first, the 3rd electrically operated valve 11,15 is controlled ventilation.
Than prior art; The invention has the advantages that: the silencing pipeline of ventilating system is designed to the winding formula; And portion is provided with several electrically operated valves 11,13 and 15 within it, controls the wind speed of silencing pipeline 1 and the size of ventilation with this according to the test needs of reality.
It is pointed out that above-mentioned preferred embodiment is merely explanation technical conceive of the present invention and characteristics, its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
