Description
Technical field
The present invention relates to the shared exhast duct of a kind of building, the structure of pressure-varying air-exhausting duct of not mutual smoke blowing, taint of odour between particularly a kind of each floor.
Background technology
China utility model patent CN2180711Y has announced a kind of pressure variable exhausting channel, it mainly is made up of component for variable-pressure, guide pipe on the trunk line that is used for exhaust and the wall that sets within it, trunk line is provided with air inlet port, guide pipe is connected with air inlet port, its component for variable-pressure is the trihedral parts that are made of head slab, positive flat board and base platform, and its both sides press closer on the inwall of the trunk line of a corresponding side.Because the both sides of component for variable-pressure press closer on the trunk line inwall, this just goes into the position to it and installs and brought trouble, component for variable-pressure to be easy to be stuck before going into the position, so its weak point is to be not easy to the installation of component for variable-pressure.
Summary of the invention
The objective of the invention is to, provide that a kind of air-flow component for variable-pressure can not be stuck, easy-to-install structure of pressure-varying air-exhausting duct.
In order to achieve the above object, the solution that the present invention takes is, it is by the gas emission pipe that is provided with air inlet port, the gentle rheology pressure part of exhaust guide pipe is formed, the gentle rheology pressure part of described exhaust guide pipe all is arranged on the inwall of described gas emission pipe, described exhaust guide pipe is arranged on the inwall of above-mentioned gas discharge tube at described air-flow component for variable-pressure opposite or side place, remain with exhaust space between described exhaust guide pipe and the air-flow component for variable-pressure, the flow-guiding channel of above-mentioned exhaust guide pipe is connected with air inlet port on the described gas emission pipe, be characterized in, at least one side in the described air-flow component for variable-pressure both sides, the inwall of a corresponding side with described gas emission pipe maintains the gap.After maintaining the gap between said flow component for variable-pressure and the gas emission pipe inwall, its jammed phenomenon promptly can not take place.The spacing that above-mentioned gap generally can put in hand or be advisable greater than this spacing, but maintain not jammed less gap or big spacing is also passable.
The exhaust opening present position of above-mentioned exhaust guide pipe is lower than, concordant or be higher than the residing position, top of described air-flow component for variable-pressure.At least one panel of described air-flow component for variable-pressure constitutes, when it constitutes integrative-structure by front plate and bottom deflector, both connection intermediate location can be arc surfaced or sphere shape constant current contour shape, to reduce resistance to flue gas, gas, be convenient to water conservancy diversion, also can make two connection intermediate location between the flat board is bending rib (wedge angle) shape.For reducing resistance, preferably have at least one to be cambered plate in above-mentioned front plate and the bottom deflector to flue gas, gas.Certainly, also can be provided with two side panels, and maintain the gap with the gas emission pipe inwall respectively in the both sides of above-mentioned front plate, bottom deflector.The said flow component for variable-pressure can also be the parts of the integrative-structure that is made of front plate, bottom deflector, two side panels and top panel; Solid parts (as making) by cement with front, bottom guide face, end face and a side, the one side is close to the solid parts of gas emission pipe inwall; Or the solid parts (available water mud is made) with front, bottom guide face, end face and two sides, two side all maintains the gap with described gas emission pipe inwall.Above-mentioned exhaust guide pipe can be an elbow shape guide pipe (bending tube), guide pipe (being dustpan-shaped guide pipe), the cambered surface pipe (having fusiform dustpan shape guide pipe) with diapire that is made of front tube wall, diapire and two sidewalls or the water conservancy diversion mouth of pipe (the short tube mouth that exposes ring-type minor face edge from air inlet port slightly in gas emission pipe) that is arranged on the air inlet port place of above-mentioned gas discharge tube etc.The transverse shape of above-mentioned gas discharge tube can be rectangle, square, circle, Long Circle or ellipse etc.
During work, following floor discharged flue gas, gas can enter from the following air inlet port of described gas emission pipe and rise, during to the narrow space between the gentle rheology pressure part of described exhaust guide pipe, when flow is constant, the sectional area of air-flow diminishes, flow velocity promptly can be accelerated, can make the exhaust ports of exhaust guide pipe this moment is negative pressure or zero-pressure, thereby can not make following floor flue gas, gas blow back into This floor, the flue gas of This floor, gas then can enter gas emission pipe through air inlet port on the described gas emission pipe and exhaust guide pipe, and upwards discharge.
Because the present invention has adopted said structure, maintain gap (being certain spacing) between the inwall of the corresponding side of at least one side in the described air-flow component for variable-pressure both sides with gas emission pipe, and the described exhaust guide pipe outside does not hold out against with the gas emission pipe inwall yet, thereby make air-flow component for variable-pressure and the exhaust guide pipe all can be before not being fit into the position, blocked by the gas emission pipe inwall, therefore it has and is convenient to be placed into the position, the advantage of being convenient to install, simultaneously, narrowing down of said flow component for variable-pressure, also reduced material consumption effectively, suitably removed cost of manufacture low.
