Vent flow silencer.
To achieve these goals, the utility model employs following technical scheme：A kind of architectural engineering HVAC air-flow disappears
Sound device, including HVAC tube body, the left plate middle position pipe of the HVAC tube body are welded with air inlet pipe, and HVAC pipe sheet
Seal protection layer is installed, the inside of the HVAC tube body is provided with escape pipe, and the side of escape pipe in the left plate of body
Port, which is welded with sealing dividing plate, the escape pipe, is welded with permeability cell, and the opposite side port of the escape pipe is welded with
Cool down and hollow radiating tube is installed on the outside of support bar, and cooling support bar, the port of the hollow radiating tube is provided with out
Tracheae.
It is used as further describing for above-mentioned technical proposal：
It is welded with the inwall of the permeability cell between gland, and gland and is provided with flexible connecting rod.
It is used as further describing for above-mentioned technical proposal：
Limited location fixing card is welded on the outer wall of the seal protection layer, and spacing fixing card is provided with two altogether.
It is used as further describing for above-mentioned technical proposal：
The outer wall middle position of the seal protection layer is provided with threaded connector.
It is used as further describing for above-mentioned technical proposal：
The escape pipe, cooling support bar and air inlet pipe three are in same horizontal line.
It is used as further describing for above-mentioned technical proposal：
Sealing delivery pipe 3 is installed in the inwall of the HVAC tube body 5.
In the utility model, escape pipe and permeability cell, and permeability cell ratio are installed in the inside of HVAC tube body first
Escape pipe is big, and the air come out from escape pipe changes its direction, is then come out from permeability cell so that the direction of outlet is changed
Become, so as to accomplish the effect eliminated the noise, the effect of this kind of mode noise reduction more preferably, is secondly installed inside the escape pipe of HVAC tube body
There is cooling support bar, for the advanced cooling treatment of heating gushed out, so as to ensure that gas outlet will not be affected by temperature
It is deformed, it is ensured that the normal of HVAC tube body is used, and finally telescopic supporting rod is internally provided with permeability cell, for larger
Air pressure impact type, play a part of one buffering so that HVAC tube body in the case where bearing pressure, carry out self protect
Shield, so as to extend the service life of HVAC tube body.
