Heating and ventilation airflow silencer for constructional engineering

Abstract

The invention provides a heating and ventilation airflow silencer for constructional engineering. The heating and ventilation airflow silencer comprises a box body structure, wherein a reinforcing structure is mounted at the left end of the box body structure, an inlet structure is mounted at the left end of the reinforcing structure, an inner pipe structure is mounted in the box body structure, a noise elimination structure is mounted between the inner pipe structure and the box body structure, and an outlet structure is fixed at the right end of the box body structure. The inlet structure further comprises four sets of mounting heads and balance rings, wherein the mounting heads are mounted at the outer end of the reinforcing structure, the four sets of mounting heads are arranged in a circumferential array, the balance rings are hinged to each set of mounting heads, each balance ring is divided into an inner layer and an outer layer, and the balance rings are hinged to the mounting heads; and meanwhile, the inner-layer balance rings and the outer-layer balance rings are hinged to each other, so that the balance rings can be kept in a balanced state all the time, the mounted inlet structure can bear multidirectional external force, and the stabilizing effect of the inlet structure is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of construction engineering equipment, and more specifically relates to a construction engineering HVAC muffler. Background technique [0002] Building HVAC, the main functions of HVAC include: heating, ventilation and air conditioning. The comprehensive abbreviation of these three functions is HVAC. HVAC is a household central air conditioner. The biggest feature of central air conditioner is that it can create a comfortable indoor environment. The general split air conditioner in the home can only solve the heating and cooling problem, but cannot solve the air treatment process. The heating of large buildings mostly sends hot air to each room through the HVAC pipe. friction, resulting in noise, so a muffler will be installed when entering the room. [0003] Application number: In the patent of CN201820499497.X, the invention discloses a construction engineering HVAC muffler, which includes a HVAC pipe jo...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a muffler for heating and ventilation air flow in construction engineering to solve the friction between the warm air inside the existing pipeline and the pipeline, resulting in noise. Therefore, a muffler will be installed when entering the room, but the existing The overall structure of the current muffler is relatively simple, and it can only be used for single-layer or single-group muffler, which cannot achieve the corresponding muffler effect, and the overall pipeline will shake when the airflow is too large. The general muffler does not have the ability to dampen the pipeline problem of effect
