Design feature of the present utility model and operating principle:

The utility model is with wind, building, ventilating duct is used as a system and is considered, a building, it provides the air flue except ventilating duct is arranged, the air flue that also can have other, such as, the slit of door and window, exterior wall, the hole of indoor wall etc. is communicated to other sides of building, and when wind when the front blows, be in wind surface ventilating pipe can and other leeward sides exist go out the interruption-forming communication path, when there is pressure differential in they, air will flow to the low place of pressure from the high place of pressure, be simplified to incompressible permanent flowing if this air flowed, how many air unit interval flows into so, also will flow out how many air, if in order to prevent that wind is blown into from the air duct inlet, install the various measures that stop above additional, played the effect that increases the air flue resistance, can reduce the flow of this path, but also weaken ventilatory function accordingly.

The same with other prior aries or the similar feature of the utility model is the direction that is blown into of avoiding the outlet of extract duct directly to aim at wind, in order to avoid wind directly is blown into pipeline, but the windproof extract duct of wind-force is more paid attention to guide functions and shunting action to being blown into wind.

An important feature of the windproof stack of wind-force is the method for utilization to distinguished and admirable acceleration, form relative low pressure at the exhaust outlet place, reaching the guiding indoor gas outwards flows out and the windproof purpose that is blown into, therefore do not stop for wind, but it is quickened, also be that requirement reduces resistance as far as possible to the discharge gas part of pipeline.The place that air velocity increases, pressure must reduce, so place at the stack road junction, distinguished and admirable speed is increased, and during incompressible gas flow, its sectional area is more little, flow velocity is just fast more, the windproof stack of this wind-force uses two kuppes up and down in main gas outlet when design, six to nine vertical flow deflectors, and the geometric cross section is long-pending when making wind cross the gas outlet reduces.Above following kuppe, horizontal flow deflector is installed, it prevents that the wind of certain downward direction directly is blown into the stack road junction, or makes the wind of horizontal direction be blown into the stack road junction when preventing alignment error.The angle that the effect of flow deflector, kuppe makes the wind of horizontal direction and discharges the direction of gas in the pipeline is less than or equal to 90 °.

The windproof stack of wind-force of drawing for wall from the side, below stack, also has assist openings, the major function of this opening is to make the foreign matter that falls into can drop out and manage the discharge of interior ponding, it also has the slight effect that inner air tube is discharged, to prevent that wind from pouring into from this mouth, its opening diameter should be far smaller than the diameter of main gas outlet.

Please refer to Fig. 9, for the windproof stack of the wind-force of drawing, because the lower end of pipe is fully indoor, so assist openings does not need aerodynamic characteristics, as long as can clear up the foreign matter that falls into and discharge ponding from top of building.

Structure of the present utility model is all right:

1. for improving its degassing function, the horizontal flow deflector of multilayer can be arranged, the windproof stack of wind-force of drawing for wall from the side, because the effect of side wall is arranged, vertical and horizontal flow deflector can be spool asymmetric.

2. the shape of cross section of vertical flow deflector can be streamlined, dull and stereotyped sheet type, camber, round, ellipse, also can only play a part to connect and support kuppe up and down, so the quantity of upright support post and vertical flow deflector can be from one to ten.

3. by reducing its speed air flow, weaken its antihypertensive effect, can also play the effect of air inlet ventilating pipe with certain protection effect.
