Abstract
The utility model discloses a warm class silencer of ventilating of building engineering, including air duct, silencer body and noise -damping bowl, the one end of air duct is connected with the outlet duct of warm siphunculus, the other end and silencer body intercommunication, the silencer body includes casing, amortization sponge, backup pad, rubber amortization area, cowling panel and venthole, and wherein, the amortization sponge is laid on the inside wall of casing, and install in the backup pad in rubber amortization area, and the backup pad is fixed in the inside of casing, and the inside at the casing is installed to the cowling panel. This warm class silencer of ventilating of building engineering simple structure, design benefit has set up the amortization mechanism that is corrugated cowling panel, rubber amortization area, amortization sponge and noise -damping bowl and constitutes on it, and the cowling panel can make the air speed step -down of original high -speed operation, and then has reduced the noise, sound that the warm siphunculus of absorption that it can be fine produced when giving vent to anger, noise cancelling effect is obvious, and the cost is low, easily promotes.
Description
Technical field
This utility model relates to building engineering equipment technical field, is specially a kind of architectural engineering HVAC airflow muffler.
Background technology
Acoustic filter is the device of abatement pneumatic noise, is installed in pipeline or on inlet and outlet mouth, air-flow by while noise had certain consumption.Existing acoustic filter soundproof effect is poor, and intake and exhaust resistance is bigger, and air flow property is poor, greatly reduces the reliability of acoustic filter work.
In recent years, acoustic filter also has application on architectural engineering HVAC, but does not the most also have good architectural engineering HVAC airflow muffler, and therefore, we are badly in need of designing a kind of acoustic filter and solve the problems referred to above.
Utility model content
The purpose of this utility model is to provide a kind of architectural engineering HVAC airflow muffler, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of architectural engineering HVAC airflow muffler, including airway, muffler body and noise-damping bowl, one end of described airway is connected with the escape pipe of HVAC pipe, the other end of airway connects with muffler body, described muffler body includes housing, noise reduction sponge, gripper shoe, rubber noise reduction band, cowling panel and venthole, wherein, noise reduction sponge is laid on the medial wall of housing, rubber noise reduction band is installed on the supporting plate, gripper shoe is fixed on the inside of housing, cowling panel is arranged on the inside of housing, and cowling panel is positioned at the lower section of gripper shoe, venthole is opened on the sidewall of housing, and noise-damping bowl is installed in venthole.
Preferably, described cowling panel undulate, and cowling panel is connected by screw with housing.
Preferably, the internally installed of described airway has Air Filter, and airway removably connects with muffler body.
Preferably, described noise-damping bowl and venthole are by snapping connection.
Compared with prior art, the beneficial effects of the utility model are: this architectural engineering HVAC airflow muffler simple in construction, design ingenious, the silencer mechanism that the cowling panel of undulate, rubber noise reduction band, noise reduction sponge and noise-damping bowl are constituted it is provided with on it, cowling panel enables to the air velocity step-down of original high-speed cruising, and then reduce the possibility producing noise, architectural engineering HVAC airflow muffler can be good at absorbing the sound produced when HVAC pipe is given vent to anger, erasure effect is obvious, and cost is low, it is easy to promote.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is internal structure schematic diagram of the present utility model；
Fig. 3 is the structural representation of this utility model noise-damping bowl.
In figure: 1, airway, 2, muffler body, 3 noise-damping bowls, 21, housing, 22, noise reduction sponge, 23, gripper shoe, 24, rubber noise reduction band, 25, cowling panel, 26, venthole.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1-3，A kind of technical scheme of this utility model offer: a kind of architectural engineering HVAC airflow muffler，Including airway 1、Muffler body 2 and noise-damping bowl 3，One end of airway 1 is connected with the escape pipe of HVAC pipe，The other end of airway 1 connects with muffler body 2，Muffler body 2 includes housing 21、Noise reduction sponge 22、Gripper shoe 23、Rubber noise reduction band 24、Cowling panel 25 and venthole 26，Wherein，Noise reduction sponge 22 is laid on the medial wall of housing 21，Rubber noise reduction band 24 is arranged in gripper shoe 23，Gripper shoe 23 is fixed on the inside of housing 21，Cowling panel 25 is arranged on the inside of housing 21，And cowling panel 25 is positioned at the lower section of gripper shoe 23，Venthole 26 is opened on the sidewall of housing 21，And noise-damping bowl 3 is installed in venthole 26，Cowling panel 25 undulate，And cowling panel 25 is connected by screw with housing 21，The internally installed of airway 1 has Air Filter，And airway 1 removably connects with muffler body 2，Noise-damping bowl 3 and venthole 26 are by snapping connection.
Cowling panel 25 reduces the speed of air-flow, makes milder the spraying in venthole 26 of air-flow, reduces the possibility of sounding, and noise-damping bowl 3, noise reduction sponge 22 compound rubber noise reduction band 24 use, and further serve the effect of noise reduction.
Above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive equivalent or change in addition according to the technical solution of the utility model and improvement thereof, all should contain in protection domain of the present utility model.
