Description

A kind of multipurpose ventilation duct

Technical field

The utility model belongs to field of ventilation equipment, and in particular to a kind of multipurpose ventilation duct.

Background technology

With air pollution getting worse, people increasingly pay attention to indoor air quality, and ventilating system is more and more It is used for indoor air purification.

It is universal with indoor ventilation equipment, during the family's installation ventilation shaft fitted up, pipe occupied space, and Can not be concordant with wall, cleaning also inconvenience is swept on pipe surface top, some is brought to ask to the layout designs of installation and pipeline Topic.

Invention content

For problems of the prior art, the utility model provides a kind of multipurpose ventilation duct, installs practicality flexibly, Blast pipe and exhaust duct can be used as to use.

To achieve the above object, the utility model uses following technical scheme：

A kind of multipurpose ventilation duct, the ventilation duct include sequentially connected crossover flange, square tube, side turn circle reducer and circle Pipe, the side turn circle reducer and include pipe interface, reducer and square tube interface, the pipe interface and socket joint phase in pipe It connects, the square tube interface connects with square tube, and the lower surface of the pipe interface and the lower surface of square tube interface are in same level On, the reducer, by justifying change side's reducing, is set by the runner of pipe interface to square tube interface between the square tube interface and square tube There is sealing element.

Air-valve shell is arranged in the pipe, at least two stay hooks are equipped on air-valve outer casing inner wall, in fixation Air valve blades are linked on hook.

The air valve blades be circular sheet-like structures, the internal diameter no more than air-valve shell of the radius of the air-valve, from room It is inside blown out, air valve blades are opened, and in the case of wind, valve block is closed from gravity.

The sealing element rubber ring or foam seal circle enhance the air-tightness of entire ventilation duct.

Protective cover is equipped in the free end of the pipe, disclosure satisfy that ventilation duct waterproof, anti-bird and dust-proof wait require.

The crossover flange, square tube, side turn circle reducer, pipe, air-valve shell are ABS materials or PVC material.

Compared with prior art, the beneficial effects of the utility model are：

Square tube patch wall installation can be realized in the utility model, aesthetics relevance grade is improved, and side turns circle reducer Use, disclosure satisfy that out the water drilling trepanning of wall part be pipe connection request；The utility model stroke valve can be opened flexibly, Air-valve is automatically closed when becalming only, moreover, can be used when air-valve and air-valve shell is not provided with as blast pipe, When pipe and when protective cover is only selected to may be used as back side blast pipe and use, when select pipe, air-valve shell and air valve blades and Back side exhaust duct is may be used as during protective cover to use.

Specific embodiment

As shown in Figs. 1-3, the present embodiment multipurpose ventilation duct, the ventilation duct include sequentially connected crossover flange 1, square tube 2nd, side turns circle reducer 3 and pipe 6, and the side turns circle reducer 3 and includes pipe interface 31, reducer 32 and square tube interface 33, The pipe interface 31 connects with socket joint in pipe 6, and the square tube interface 33 connects with square tube 2, under the pipe interface 31 Surface and the lower surface of square tube interface 33 are in same level, and the reducer 32 is by pipe interface 31 to square tube interface 33 Runner is equipped with sealing element by justifying change side's reducing between the square tube interface 33 and square tube 2.

Preferably, the present embodiment is arranged with air-valve shell 4 in the pipe 6, it is equipped with extremely on 4 inner wall of air-valve shell Few two stay hooks, are linked with air valve blades 5 on stay hook.

As further preferred, the present embodiment air valve blades 5 are circular sheet-like structures, and the radius of the air-valve is not more than The internal diameter of air-valve shell.

Preferably, the present embodiment sealing element rubber ring or foam seal circle.

As further preferred, the present embodiment is equipped with protective cover 7 in the free end of the pipe 6.

As still more preferably, the present embodiment crossover flange 1, square tube 2, side turn circle reducer 3, pipe 6, air-valve shell 4 be ABS materials or PVC material.

When the present embodiment is in fresh air system, indoor ventilation apparatus is opened, and wind enters from protective cover, successively by pipe 6, Side turns circle reducer 3, square tube 2 and crossover flange 1 and enters in new wind turbine.
