Abstract
The utility model relates to a diversion check exhaust passage comprising a main pipeline. The side wall of the main pipeline is provided with an air inlet. The diversion check exhaust passage is characterized in that a diversion pipe is arranged at the air inlet; the diversion pipe is a spade-shaped structure with an upward opening; the diversion pipe is surrounded at the air inlet; the diversion pipe and the pipe wall of the main pipeline surround into a diversion passage; and a check device is also arranged at the air inlet. The diversion check exhaust passage can play a role of pressure transformation through the diversion pipe surrounded on the air inlet and also play the roles of voltage transformation and guiding, the check device is arranged so as to avoid the phenomenon that gas of the upper layer goes back to the interior of a door of a resident of the lower layer, and the exhaust capacity is improved and the phenomenon of air inversing is avoided on the premise of not affecting the function of pressure transformation.
Description
Technical field
The utility model relates to a kind of water conservancy diversion non-return exhaust duct, particularly a kind ofly is used for the exhaust duct that all kinds of dwelling houses discharging flue gases are used.
Background technology
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, concentrates by trunk line and discharges.
At present, normally used is the pressure swing type exhaust uptake, promptly by variable-pressure plate or transformation piece are set in trunk line, realize the conversion of dynamic pressure and static pressure, can reduce the phenomenon of smoke blowing taint of odour, but adopt this kind structure, occupy the major part space of trunk line, influenced capacity, and may occur still that the flue gas on upper strata is counter goes into the indoor phenomenon of resident family of lower floor.
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, under the prerequisite that does not influence the transformation function, has improved capacity, and avoided the water conservancy diversion non-return exhaust duct of anti-gas phenomenon.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of water conservancy diversion non-return exhaust duct, comprise trunk line, have air inlet port on the sidewall of trunk line, it is characterized in that: the air inlet port place is provided with mozzle, mozzle is the scoop structure of upward opening, mozzle is enclosed in the air inlet port place, and the tube wall of mozzle and trunk line surrounds honeycomb duct, and the air inlet port place also is equipped with check device.
The mozzle that is enclosed in the air inlet port place can play transformer action, can also play guide effect.
Described check device can be full open type flap valve, semi-open type flap valve or laterally opened flap valve, check device is set can avoids that the flue gas on upper strata is counter goes into the indoor phenomenon of resident family of lower floor.
The width of described honeycomb duct is 6～9CM, and to guarantee the capacity of trunk line, the angle of the body of mozzle bottom and the tube wall of trunk line is 45～60 °, can improve water conservancy diversion and transformation effect.
The beneficial effect that the utility model had is: water conservancy diversion non-return exhaust duct is by being enclosed in the mozzle at air inlet port place, can play transformer action, can also play guide effect, check device is set avoids that the flue gas on upper strata is counter goes into the indoor phenomenon of resident family of lower floor, under the prerequisite that does not influence the transformation function, improve capacity, and avoided anti-gas phenomenon.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, trunk line; 2, air inlet port; 3, mozzle; 4, check device; 5, honeycomb duct.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, have air inlet port 2 on the sidewall of trunk line 1, air inlet port 2 places are provided with mozzle 3, mozzle 3 is the scoop structure of upward opening, mozzle 3 is enclosed in air inlet port 2 places, mozzle 3 surrounds honeycomb duct 5 with the tube wall of trunk line 1, and air inlet port 2 places also are equipped with check device 4, and check device 4 can be full open type flap valve, semi-open type flap valve or laterally opened flap valve.
Be enclosed in the mozzle 3 that air inlet port 2 goes out and play transformer action, can also play guide effect, check device 4 is set avoids that the flue gas on upper strata is counter goes into the indoor phenomenon of resident family of lower floor.
