Abstract
The utility model relates to a silence case for air pipe system relates to ventilation system or central air conditioning wind system air return pipeline amortization and pipeline connecting structure all. This silence case has an inner chamber, is equipped with air intake and air outlet on this silence case, be fixed with the amortization cotton on the inner wall of this silence case the cotton outer fixed foraminiferous flat board that is covered with of amortization, foraminiferous flat board is fixed in the amortization cotton on the silence incasement wall. Adopt above -mentioned technical scheme, when multicell return air, bleeder and the main tuber pipe department of being connected installation silence case can be easy to assemble, save installation time, improve the installation effectiveness, install the silence case simultaneously and as the transition of bleeder with main tuber pipe, make the air current obtain certain buffering, reduce the impact of air current to main tuber pipe greatly to reduce the noise that this process of converging produced, it prolongs whole ventilation system's life -span to do.
Description
Technical field
A kind of silencing case for ventiduct system of this utility model is related to ventilating system or central air-conditioning wind system
Air return pipeline noise reduction and pipeline jointing construction.
Background technology
In the ventilating system and central air-conditioning wind system of prior art, when each branched pipe is connected with air main, need are special very
Connectors, such as reducing, circle changes side, side be rounded, quarter bend, install also very take work consuming, waste of materials, installation
Also not convenient, work efficiency is relatively low.And when in use namely during ventilating system normal work, due to each branched pipe blast and
Wind speed and air main are all inconsistent, and when multitube return air, the air of each branched pipe can produce noise when into air main, and
And noise is especially big, air mixing is also insufficient, has not both met noise environmental requirement, also affects the service life of ventilation shaft,
With greater need for the normal maintenance maintenances of Jing, substantial amounts of artificial material resources are expended, maintenance cost is higher.
Utility model content
A kind of silencing case and its attachment structure for ventiduct system of this utility model overcomes lacking for prior art
Fall into, it is quick and easy for installation, operation construction is both facilitated, work efficiency is improve, can effectively abate the noise again, it is to avoid noise is disturbed
The people, are allowed to meet environmental requirement.
A kind of silencing case for ventiduct system of technical solutions of the utility model, it is characterised in that the silencing case has
One inner chamber, is provided with air inlet and air outlet on the silencing case；Silencing cotton is fixed with the inwall of the silencing case, described
Silencing cotton outer layer is fixed and is covered with perforated flat plate, and the perforated flat plate is fixed on silencing cotton on quiet chamber interior wall.
A kind of above-mentioned silencing case for ventiduct system, is middle folder between the inwall and outer wall of the silencing case
Layer PEF warming plates.
A kind of above-mentioned silencing case for ventiduct system, is provided with support between perforated flat plate and quiet chamber interior wall
Square through-pipe, the thickness of the square through-pipe is equal with the thickness of silencing cotton.
A kind of above-mentioned silencing case for ventiduct system, in air inlet and air outlet air intake method is respectively equipped with
Blue disk and outlet air flange disk.
Using above-mentioned technical proposal, in multitube return air, branched pipe installs silencing case with air main connection, you can side
Just install, save the set-up time, improve installation effectiveness, while installing silencing case as the transition of branched pipe and air main, make gas
Stream obtains certain buffering, greatly reduces impact of the air-flow to air main, so as to reduce the noise that this Process of Confluence is produced, also may be used
Extend the life-span of whole ventilating system.
Description of the drawings
Fig. 1 is a kind of sectional view of the silencing case for ventiduct system of this utility model.
Fig. 2 is A-A sectional views shown in Fig. 1.
Specific embodiment
Technical solutions of the utility model are further described with reference to embodiment and accompanying drawing：
It is as shown in Figure 1 and Figure 2 a kind of embodiment of the silencing case for ventiduct system of this utility model.
The silencing case 1 has an inner chamber 2, and air inlet 11 and air outlet 12 are provided with the silencing case 1；In the silencing case
Silencing cotton 3 is fixed with 1 inwall 13, is fixed in the outer layer of the silencing cotton 3 and is covered with perforated flat plate 4, the perforated flat plate 4 will disappear
Sound cotton 3 is fixed on the inwall 13 of silencing case 1.The inwall 13 and outer wall 14 of the silencing case 1 is all color steel, in inwall 13 and outward
It is intermediate course PEF warming plates 5 between wall 14, can be used for pipe insulation and eliminate echo.In perforated flat plate 4 and silencing case
Support square through-pipe 6 is provided between wall 13, the thickness of the square through-pipe 6 is equal with the thickness of silencing cotton 3.At air inlet 11 and go out
Air inlet flange disk 111 and outlet air flange disk 121 are respectively equipped with air port 12, for being connected with branched pipe with air main respectively.Such as
This, in multitube return air, branched pipe installs silencing case with air main connection, you can convenient connection branched pipe and air main,
The set-up time is saved, installation effectiveness is improved, while installing silencing case as the transition of branched pipe and air main, makes air-flow obtain one
Fixed buffering, the perforated flat plate 4 and silencing cotton 3 in plenum chamber can be used to further buffer gas flow and reduce noise, can obtain again
Even static pressure air-out, reduces kinetic pressure losses, and plenum chamber is applied to well in ventilating system, can improve the synthesis of ventilating system
Performance.The thickness that the square through-pipe 6 is used for supporting fixed belt hole flat board 4 to ensure silencing cotton 3 is impartial, preferably abates the noise.
Preferred embodiment of the present utility model is these are only, this utility model is not limited to, for this area
Technical staff for, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle within,
Any modification, equivalent substitution and improvements made etc., should be included within right of the present utility model.
