Abstract
The utility model belongs to a wind cap for all classes of chimneys, and is particularly suited to the exhaust passage chimneys of general buildings. The wind cap for all classes of chimneys is characterized in that the wind cap is composed of a top cap, an up convex circular arc body, a down convex circular arc body, a support rod and a transition cone; the top cap is a cone, and the lower end of the top cap is fixed with the periphery of the up convex circular arc body; the up convex circular arc body and the down convex circular arc body are connected by the support rod, and the down convex circular arc body is connected with the small-size air current outlet end of the transition cone. The wind cap for all classes of chimneys is a self forced wind cap which effectively reduces smoke discharging resistance, prevents interference of wind force, and eliminates wind back flowing phenomenon. The wind cap for all classes of chimneys has simple structure and low production cost.
Description
The utility model belongs to all kinds of chimney emission gas outlet blast caps, is specially adapted to the blast cap of general building exhaust passage chimney.
Original common blast cap makes ventilation effect be affected owing to often be subjected to the interference of external wind-force often to violate wind-fall filling phenomenon, even does not have gas exchange action.
The purpose of this utility model is: provide a kind of and can effectively reduce the smoke evacuation resistance, prevent that wind-force from disturbing, a kind of self-operated type blast cap of phenomenon, its low production cost simple in structure are irritated in the criminal's of elimination wind-fall.
The technical solution of the utility model is: design a kind of self-operated type blast cap, it is characterized in that: it is made up of top cover, epirelief circular arc body, following protruding circular arc body, support column, transition-cone, and top cover is a cone, fixedlys connected with epirelief circular arc body periphery in the top cover lower end; The epirelief circular arc body be connected by support column between the protruding circular arc body down, following protruding circular arc body is connected the little airflow outlet end of transition-cone size.
Described protruding circular arc body center down has through hole to be connected with the transition-cone port of export, and the transition-cone middle part is a conulite, and the size of bottom nozzle, shape are to match with size, the shape of flue outlet to be connected.Described down protruding circular arc body and epirelief circular arc body protruding withstands on the center line of blast cap, and distance is the shortest between the two protruding tops, all the other along with camber line from protruding apex distance from increase up and down the distance between protruding circular arc body camber line also increase gradually.
Characteristics of the present utility model are: up and down between two dome arcs, two convex surfaces are opposing thirty years of age, and fixed by three support columns, form eel-like figure horn mouth shape, according to hydrodynamics, aerodynamics.Relevant bernoulli principle and venturi siphonage, different import wind speed produces the high velocity air of several times and even tens of times at middle part contraction mouth place, pressure reduces around making air-flow, exhaust opening pressure reduces, and produces the siphonage of air-flow then, makes the flue gas discharge flue that rises rapidly.Air velocity is big more, and pressure is just more little, and the interior draft of flue ambassador's flue gas more just can come up more smoothly, can not violate wind-fall and irritate phenomenon.Following dome nock middle part is opened round mouth and is linked to each other the very simple compactness of structure with the flue gas hole.
A kind of self-operated type blast cap does not need any additionaling power energy and other mechanical device, no matter wind can both solve the resistance of fume emission smoothly from which direction, overcomes the problem that the interference that is subjected to wind-force is poured in down a chimney smoke backflow, is the desirable blast cap that all chimneys are discharged cigarettes.
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Among the figure: 1, top cover 2, epirelief circular arc body 3, following protruding circular arc body 4, support column 5, transition-cone 6, flue outlet.
