Description
Technical field
The utility model relates to the parts that use on a kind of building, particularly a kind of component for variable-pressure that is used to prevent the pressure variable exhausting channel of smoke blowing mutually, taint of odour between all kinds of buildings and each floor of residence building.
Background technology
China utility model patent CN2180711Y discloses a kind of pressure variable exhausting channel, it is by trunk line, the guide pipe of wall sets within it, transformation part and the air inlet port that is arranged on its tube wall constitute, described transformation part and guide pipe are oppositely arranged, wherein, guide pipe and transformation part all must predetermined fixed be arranged on trunk line internal face place, this just makes its manufacture craft comparatively complicated, after the position be set determine of guide pipe and transformation part, just change again, if being provided with the position, it just is suitable for the use of air-exhaust type oil-fume removing machine, when the user adopts the down air-exhaust type oil-fume removing machine, then can not be suitable for so, use very inconvenience.In addition, it can not realize that each parts is building a building job site assembling, and must make the place with trunk line is made an integral body at trunk line, must integral manufacturing, whole Transporting, and can not the split transportation, this also makes its transportation comparatively inconvenient.Guide pipe, transformation part predetermined fixed are arranged on the structure in the trunk line, make it can not be used to transform original common exhaust duct road, the common exhaust duct road is become have transformation, the pressure swing type extract duct of anti-smoke blowing, anti-taint of odour function.Therefore, its fault is, complex manufacturing technology, and transportation and use inconvenience can not be used to transform original common exhaust duct road.
Summary of the invention
The purpose of this utility model is, overcomes the deficiency of prior art scheme, and provides a kind of being easy to make, transportation, easy to use, and can be used for transforming the component for variable-pressure of the pressure variable exhausting channel in original common exhaust duct road.
In order to achieve the above object, the solution that the utility model is taked is, it comprises matrix, air inlet port and air inlet guiding parts, described air inlet port and air inlet guiding parts all are arranged on the described matrix, be characterized in, described matrix is one and is used for the parts of combine and assemble on the extract duct tube wall, described air inlet guiding parts is the parts with air inlet water conservancy diversion inner chamber, its air inlet water conservancy diversion inner chamber and described air inlet port are interconnected, constitute the air inlet flow-guiding channel, described air inlet guiding parts is arranged in the inner chamber of described extract duct.
In order to make it have the most easy structure, have transformation, anti-smoke blowing, anti-taint of odour function again, best matrix of the present utility model is the buck plate that is used to be assemblied on the described extract duct tube wall, described air inlet port is arranged on the described buck plate, and described air inlet guiding parts is arranged on the interior sidewall surface place of described buck plate towards described extract duct inner chamber.
