Description

The windproof and rain proof chimney cowl

One, technical field

The utility model relates to chimney cowl, is a kind of windproof and rain proof chimney cowl, is particularly useful for the chimney cowl of combustion gas, oil burner.

Two, background technology

Strong wind weather causes combustion gas, oil burner fire extinguishing easily, and its main cause has: first: the air stream on chimney top was pressed low, and burned flame is elongated, and when flame is elongated away from the burner root, can causes flame to take off fire and extinguish; Second: cause by tempering, the reason of tempering is that chimney is irritated in wind-fall, and pour in down a chimney mainly is that wind is blocked by terrain and its features factor, construction of structures to cause, like this, because the fire extinguishing of combustion gas, oil burner causes potential safety hazard easily and has reduced the operating efficiency of combustion gas, oil burner.

Three, summary of the invention

The utility model provides a kind of windproof and rain proof chimney cowl, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the problem that strong wind weather causes combustion gas, oil burner fire extinguishing easily.

The technical solution of the utility model realizes by following measure: a kind of windproof and rain proof chimney cowl comprises chimney, wind loop, goes up cowling panel and following cowling panel; Wind loop is installed in the outside of chimney, between wind loop and the chimney space is arranged, and the top of wind loop is higher than the top of chimney, cowling panel on having above the wind loop, and last cowling panel is fixedly mounted on the wind loop; Following cowling panel is arranged below wind loop, and following cowling panel is fixedly mounted on the chimney.

Be further optimization and/or improvements below to above-mentioned utility model technical scheme:

The lower end of above-mentioned wind loop can be installed in the outside of chimney by the gusset that is no less than, and last cowling panel is fixedly mounted on the wind loop by gusset.

But six to ten times of the height chimney inner radial of above-mentioned wind loop.

But 3/5ths of the height wind loop height of above-mentioned wind loop inner chimney.

Above-mentioned go up between cowling panel and the wind loop top distance and/or down bottom cowling panel and the wind loop between distance can be the chimney inner radial square divided by the wind loop inside diameter.

The above-mentioned radius of going up cowling panel and/or following cowling panel can be 0. 6 times of wind loop inside diameter.

The utility model reasonable and compact in structure, the air stream that can effectively prevent the chimney top pressed low or tempering to cause the fire extinguishing of combustion gas, oil burner, thereby greatly reduce because the potential safety hazard that the fire extinguishing of combustion gas, oil burner causes, effectively raise the operating efficiency of combustion gas, oil burner.

Four, description of drawings

Accompanying drawing 1 is the main TV structure schematic diagram of the utility model most preferred embodiment.

Coding in the accompanying drawing is respectively: 1 is chimney, 2 is wind loop, 3 is gusset, and 4 is last cowling panel, and 5 are following cowling panel, 6 is the outlet of chimney, 7 is the chimney upper limb, and h is distance or the following distance of cowling panel between bottom wind loop between last cowling panel and the wind loop top, and r1 is the chimney inner radial, d2 is the wind loop inside diameter, and r3 is the radius of last cowling panel or the radius of following cowling panel.

Five, the specific embodiment

The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

Below in conjunction with embodiment and accompanying drawing the utility model is further described:

As shown in Figure 1, this windproof and rain proof chimney cowl comprises chimney 1, wind loop 2, goes up cowling panel 4 and following cowling panel 5; Wind loop 2 is installed in the outside of chimney 1, between wind loop 2 and the chimney 1 space is arranged, and the top of wind loop 2 is higher than the top of chimney 1, cowling panel 4 on having above the wind loop 2, and last cowling panel 4 is fixedly mounted on the wind loop 2; Following cowling panel 5 is arranged below wind loop 2, and following cowling panel 5 is fixedly mounted on the chimney 1.When wind was bottom horizontal flow sheet, wind loop 2 top and the bottom were that identical air stream is pressed, and outlet 6 places of chimney are relative static pressure, alleviated greatly than the influence of low flow pressure to flame, so flame can not be elongated and takes off fire and extinguish; During wind under oblique, last cowling panel 4 has blocked the wind under oblique, can prevent that the wind under oblique from forming downdraught; When obliquely wind, following cowling panel 5 has also blocked wind obliquely, can prevent the downdraught that wind obliquely forms after last cowling panel lower surface reflection, go up cowling panel 4 simultaneously and can also play the effect of blocking sleet that the diameter of general wind loop 2 is than the big pipe level of diameter of chimney 1.

Can according to actual needs above-mentioned windproof and rain proof chimney cowl be made further optimization and/or improvements:

As shown in Figure 1, for the ease of installing and ventilate, the lower end of wind loop 2 is installed in the outside of chimney 1 by the gusset 3 that is no less than, and last cowling panel 4 is fixedly mounted on the wind loop 2 by gusset 3.

As shown in Figure 1, in order to keep out the wind preferably, the height of wind loop 2 is six to ten times of chimney 1 inner radial.

As shown in Figure 1, for outlet 6 places that make chimney reach static pressure preferably, the height of wind loop 2 inner chimneys 1 is 3/5ths of wind loop 2 height.

As shown in Figure 1, in order to reach windproof effect preferably, the distance h between last cowling panel 4 and wind loop 2 tops is that r1 square of chimney inner radial is divided by wind loop inside diameter R2; Perhaps, the distance h between following cowling panel 5 and wind loop 2 bottoms be chimney inner radial r1 square divided by wind loop 2 inside diameter R2; Perhaps, the distance h between distance h between last cowling panel 4 and wind loop 2 tops and following cowling panel 5 and wind loop 2 bottoms be chimney 1 inner radial r1 square divided by wind loop 2 inside diameter R2.

As shown in Figure 1, in order to reach windproof effect preferably, the radius r 3 of last cowling panel is 0. 6 times of wind loop inside diameter R2; Perhaps, the radius r 3 of following cowling panel is 0. 6 times of wind loop 2 inside diameter R2; Perhaps, the radius r 3 of last cowling panel 4 and following cowling panel 5 is 0. 6 times of wind loop 2 inside diameter R2.

Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
