Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The utility model provides a silence pipeline structure, including main line 1, air outlet 2 and pipeline end cover 3, install two air outlets 2 on main line 1 at least, the one end at main line 1 is established to the fixed lid of pipeline end cover 3, wind makes an uproar and produces the reflection when meetting pipeline end cover 3, wind makes an uproar and produces the decay at the reflection in-process, thereby reduce wind and make an uproar, through setting up a plurality of air outlets 2 on main line 1, when the air current in main line 1 flows through air outlet 2, form the vortex, wind makes an uproar when passing through air outlet 2, form the decay, thereby reduce the wind of air outlet 2 department and make an uproar, reduce the noise that new trend system produced, thereby to indoor staff when reducing new trend system and sending wind, the student causes the influence.
The air output of the air outlet 2 at the farthest end of the pipeline end cover 3 is smaller than the air output of other air outlets 2, and the air noise can be attenuated when passing through the three-way pipe by reducing the air output of the air outlet 2 at the farthest end, so that the air flow forms turbulent flow at the air outlet 2 at the farthest end, and the air noise at other air outlets 2 is reduced.
In this embodiment, two air outlets 2 are fixedly mounted on the main pipe 1, which are respectively the first air outlet 4 and the second air outlet 5, the distance between the first air outlet 4 and the pipe end cover 3 is greater than the distance between the second air outlet 5 and the pipe end cover 3, the air output of the first air outlet 4 is less than the air output of the second air outlet 5, and by reducing the air output of the first air outlet 4, the airflow in the main pipe 1 forms turbulent flow at the position of the first air outlet 4, so as to reduce the wind noise at the second air outlet 2.
Further, for user control, the first air outlet 4 is in a normally closed state, no air is discharged from the first air outlet 4, and when the airflow passes through the first air outlet 4, the airflow speed is reduced, and the wind noise is attenuated, so that the wind noise at the second air outlet 5 is reduced.
First air outlet 4 and second air outlet 5 are through glue 12 fixed connection between, glue 12 adopts the special glue of PVC material, directly is connected first air outlet 4 and second air outlet 5.
Or, the first air outlet 4 and the second air outlet 5 are fixedly connected through a connecting pipe 6, and the distance between the air outlet opening of the first air outlet 4 and the air outlet opening of the second air outlet 5 can be adjusted through the connecting pipe 6.
The air-out orientation of adjacent air outlet 2 is unanimous, promptly, and the port of adjacent air outlet 2 is located the coplanar, prevents that the air current from forming the vortex in main line 1, leads to the vortex effect of farthest end air outlet 2 to weaken, further influences the performance of making an uproar of falling of other air outlets 2.
Be equipped with spacing piece 10 on the lateral wall of wind gap bayonet joint 8, cover 7 joints in air outlet 2 with the wind gap through spacing piece 10, preferably, spacing piece 10 is flexible rubber material, and the end connection of wind gap bayonet joint 8 has sealing ring 11, through the setting of sealing ring 11, is convenient for improve the sealing performance of wind gap bayonet joint 8 and air outlet 2.
The air outlet 2 is a three-way connecting pipe.
This silence pipeline structure's the principle of making an uproar is, wind makes an uproar and removes to 3 departments of pipeline end cover through the gas that flows, wind makes an uproar and produces the rebound, wind makes an uproar and can produce the partial decay at the rebound in-process, thereby reduce wind and make an uproar, it is same, the air outlet that will be close to pipeline end cover 3 is closed, can make an uproar equally to wind and carry out the rebound, thereby further reduce wind and make an uproar, the air outlet is three way connection pipe, wind makes an uproar behind three way connection pipe, wind makes an uproar and forms the decay, the setting of the decay is made an uproar through the wind.
