Description

Technical Field

[0001] The utility model relates to the design field of ventilation and air - conditioning systems in the construction field, and particularly relates to an air outlet deceleration device applied to high - speed ventilation ducts. Background Technique

[0002] In the design of underground culverts such as subway spaces, it is necessary to design ventilation and air - conditioning systems in enclosed spaces.

[0003] Existing ventilation and air - conditioning systems usually have relatively low wind speeds. That is to say, after the ventilation and air - conditioning systems are designed, the cross - section of the air ducts is generally large, which makes the later installation difficult, wastes manpower, material resources and time. At the same time, the space is not fully utilized and the construction cost is high.

[0004] However, during the design and construction of conventional ventilation and air - conditioning systems, in order to ensure factors such as the comfort of the space and the ventilation volume, but for extensive air distribution, it is necessary to set up more air distribution outlets. Then the amount of pipeline used is very large, resulting in too many air distribution parts as a whole, difficult installation, and the construction cost of the building is not effectively reduced.

[0005] For the above reasons, if there is a new structure that can evenly distribute air, avoid high - speed air blowing directly in one direction, and achieve low - cost air distribution, the above problems can be solved. Summary of the Utility Model

[0006] Purpose of the utility model: To provide an air outlet deceleration device applied to high - speed ventilation ducts with better effects. The specific purpose can be seen from the multiple substantial technical effects in the specific implementation part.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An air outlet deceleration device applied to high - speed ventilation ducts, characterized in that

[0009] The air outlet deceleration device includes an air duct interface 1, the air duct interface 1 is connected to a housing 2, and a wind distribution plug 3 is arranged below the housing 2, and the wind distribution plug 3 is directly opposite to the middle part of the air duct interface 1; a deceleration and diffusion fin 6 is arranged above the wind distribution plug 3;

[0010] A circle of lower air outlets 4 is arranged on the lower surface of the housing 2; side air diffusion outlets 5 are arranged in a circle on the housing 2;

[0011] The lower air outlets 4 and the side air diffusion outlets 5 jointly distribute air to achieve a small - diameter and large - air - outlet surface.

[0012] A further technical solution of the utility model is that threads are arranged on the air duct interface 1, and there is an air duct thread 8 for docking the air duct on the air duct interface 1.

[0013] A further technical solution of the present utility model is that the air duct interface 1 and the outer shell 2 are straight pipes.

[0014] A further technical solution of the present utility model is that the air duct interface 1 and the outer shell 2 are flared mouths 7.

[0015] A further technical solution of the present utility model is that a circular opening is arranged on the lower surface of the outer shell 2, and this opening is the main air outlet. A threaded docking surface is arranged on the inner wall of this opening, and the circumferential air distribution plug threaded docking surface 9 of the air distribution plug 3 can be threadedly docked on this inner wall.

[0016] A further technical solution of the present utility model is that a hand-held part 10 is arranged on the air distribution plug 3.

[0017] A further technical solution of the present utility model is that the deceleration and diffuser vane 6 is an arc-shaped surface.

[0018] A further technical solution of the present utility model is that the air distribution plug 3 is a hollow structure.

[0019] A further technical solution of the present utility model is that a sound-absorbing and decelerating material is arranged on the surface of the deceleration and diffuser vane 6.
