Abstract
The utility model relates to a full-open exhaust flue which comprises a main pipeline and is characterized in that a gas inlet of the main pipeline is provided with a full-open check valve. When the full-open exhaust flue is used for exhausting flue gas, a valve plate rotates under the action of wind; and due to a large wind acted area of the bottom half part of the valve plate, the bottom half part of the valve plate rotates towards the inside of the gas inlet of the main pipeline and the top half part of the valve plate rotates towards the outside of the gas inlet of the main pipeline, so that the flue gas enters the main pipeline through a through hole of an inner cavity. After the full-open exhaust flue completes the exhausting of the flue gas, the weight of the bottom half part of the valve plate is greater than the weight of the top half part of the valve plate, and thus, under the action of gravity, the valve plate falls back, the top half part of the valve plate falls back to the position of an upper flanging and the bottom half part of the valve plate falls back to the position of a lower flanging, so that the gas inlet is closed and the gas leakage is avoided. The full-open exhaust flue has a simple structure and good using effect.
Description
Technical field
The utility model relates to a kind of exhaust uptake, particularly a kind ofly is used for the full open type exhaust uptake that all kinds of dwelling houses discharging flue gases are used.
Background technology
At present, usually use exhaust uptake to come flue gas is discharged in the dwelling house, each resident family is drained into indoor flue gas in the trunk line respectively by the air inlet port on the trunk line, concentrate by trunk line again and discharge, but in use, may occur that the flue gas on upper strata is counter goes into the indoor phenomenon of resident family of lower floor, generally adopt flap valve to avoid producing anti-gas phenomenon, but there is complex structure in normally used flap valve, problems such as air leakage phenomena are arranged.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of above-mentioned defective that solved is provided, and simple in structure, avoided the full open type exhaust uptake of air leakage phenomena.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of full open type exhaust uptake, comprise trunk line, and it is characterized in that: the air inlet port place of trunk line is equipped with the full open type flap valve.
Full open type exhaust uptake according to claim 1, it is characterized in that: described full open type flap valve comprises housing and is positioned at the intracavity through hole in housing centre position, be provided with valve block in the intracavity through hole, the both sides of valve block are connected on the housing by the valve block rotating shaft, the valve block rotating shaft is positioned at the top of intracavity through hole, the housing of intracavity through hole top and bottom is provided with the upper overturning and the following flange of mutual dislocation, the first half of valve block is positioned at the side of upper overturning towards the air inlet port outside, and flange was towards a side of air inlet port inboard under the latter half of valve block was positioned at.
During the discharging flue gas, under the wind-force effect, valve block rotates, because valve block the latter half is subjected to the wind-force area big, make the latter half of valve block rotate towards the inboard of trunk line air inlet port, the first half of valve block is rotated towards the outside of trunk line air inlet port, make flue gas enter into trunk line, after smoke evacuation finishes, because valve block the latter half weight is greater than valve block the first half by intracavity through hole, under the effect of gravity, valve block falls after rise, and the first half of valve block falls back to the upper overturning position, and the latter half of valve block falls back to down the flange position, make air inlet closure, avoided the generation of gas leak phenomenon.
The beneficial effect that the utility model had is: the full open type exhaust uptake is when the discharging flue gas, under the wind-force effect, valve block rotates, because valve block the latter half is subjected to the wind-force area big, make the latter half of valve block rotate towards the inboard of trunk line air inlet port, the first half of valve block is rotated towards the outside of trunk line air inlet port, make flue gas enter into trunk line by intracavity through hole, after smoke evacuation finishes, because valve block the latter half weight is greater than valve block the first half, under the effect of gravity, valve block falls after rise, the first half of valve block falls back to the upper overturning position, the latter half of valve block falls back to down the flange position, makes air inlet closure, has avoided the generation of gas leak phenomenon, simple in structure, result of use is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, trunk line; 2, housing; 3, valve block; 4, valve block rotating shaft; 5, upper overturning; 6, following flange.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, the air inlet port place of trunk line 1 is equipped with the full open type flap valve, the full open type flap valve comprises housing 2 and is positioned at the intracavity through hole in housing 2 centre positions, be provided with valve block 3 in the intracavity through hole, the both sides of valve block 3 are connected on the housing 2 by valve block rotating shaft 4, valve block rotating shaft 4 is positioned at the top of intracavity through hole, the housing 2 of intracavity through hole top and bottom is provided with the upper overturning 5 and the following flange 6 of mutual dislocation, the first half of valve block 3 is positioned at the side of upper overturning 5 towards the air inlet port outside, and flange 6 was towards a side of air inlet port inboard under the latter half of valve block 3 was positioned at.
During the discharging flue gas, under the wind-force effect, valve block 3 rotates, because valve block 3 the latter halfs are subjected to the wind-force area big, make the latter half of valve block 3 rotate towards the inboard of trunk line 1 air inlet port, the first half of valve block 3 is rotated towards the outside of trunk line 1 air inlet port, make flue gas enter into trunk line 1, after smoke evacuation finishes, because valve block 3 the latter half weight are greater than valve block 3 the first half by intracavity through hole, under the effect of gravity, valve block 3 falls after rise, and the first half of valve block 3 falls back to upper overturning 5 positions, and the latter half of valve block 3 falls back to down flange 6 positions, make air inlet closure, avoided the generation of gas leak phenomenon.
