Abstract
The utility model relates to a coupling type flow guiding device for residence shared air exhausting channels. The utility model discloses that the coupling type flow guiding device has a flow guiding bent pipe housing (1), the lower end of the part, which is positioned in a room, of the flow guiding bent pipe housing (1) is provided with an air inlet coupling interface (2), and the upper end of the part, which is positioned in a residence shared air exhausting channel, of the flow guiding bent pipe housing (1) is provided with an open type air outlet (4). The air outlet of the utility model can not change the air exhausting direction, and air curtains can be effectively prevented from being formed in shared air exhausting channels. The utility model has the advantages of convenient maintenance and cleaning, and also small friction resistance and clear air exhaust, and sanitary indoor environments can be kept.
Description
The utility model relates to a kind of flow guide device, particularly with the anti-matching used coupling type flow guide device of smoke blowing outlet valve of the coupling type of the shared air outlet flue of dwelling house.
Country's dwelling house design planning is clearly stipulated, on shared air outlet flue the anti-backflow facility should be set.Up to now, developed multiple shared air outlet flue product with anti-backflow function, for example: the patent No. is: " the fume centralized discharge pipe of band backstop " and the patent No. of ZL96223143.6 are: the dual check valve of the damping of ZL96219620.7.They have played certain effect for the return air taint of odour problem that solves the shared air outlet flue of dwelling house, but all have a check valve on the air guide bend pipe of these two patents, and check valve is fixed on the upper end oral area of air guide bend pipe, hat type check valve on this air guide bend pipe (perhaps horizontal retaining board) has changed discharge directions, in shared air outlet flue, form air curtain, increase gas-flow resistance, cause exhaust not smooth; In the work progress,, will increase the weight of valve plate, cause the valve opening difficulty in case the slush of falling sticks on the above-mentioned check valve (perhaps horizontal retaining board); Non-return valve plate is positioned at the upper end of air outlet flue air guide bend pipe, and air guide bend pipe and check valve are fixing as a whole, if the non-return valve plate on the air guide bend pipe is clung by greasy dirt, safeguards and clean just very inconvenience.
The purpose of this utility model provides the coupling type flow guide device of the shared air outlet flue of a kind of dwelling house, relief opening of the present utility model can not change discharge directions, prevent to form in the shared air outlet flue air curtain effectively, be easy to safeguard and clean, and surface friction drag is little, exhaust is smooth and easy, the hygienic conditions in the holding chamber.
Technical solution of the present utility model is that the coupling type flow guide device has the water conservancy diversion bending tube shell, the water conservancy diversion bending tube shell has air inlet coupling interface in the lower end that is positioned at indoor section, the water conservancy diversion bending tube shell has the open type relief opening in the upper end that is positioned at the shared air outlet flue part of dwelling house.
The above is that the water conservancy diversion bending tube shell is that a bent angle is the bend pipe of 90 degree, and its inferior horn is the cambered surface wall of rounding off, or the water conservancy diversion bending tube shell is the bend pipe of a rounding off.
Have in the utility model water conservancy diversion bending tube shell and make the air-flow arc guide plate that is no less than a slice upwards of can slick and sly turning.
The cross section of above the utility model air inlet coupling interface and open type relief opening can be circular or square, polygonal.
The utility model air inlet coupling interface is vertical mutually with the center line of open type relief opening.
The utility model air inlet coupling interface can be matched with the anti-smoke blowing outlet valve of the coupling type of shared air outlet flue.
Working principle of the present utility model is that the coupling type flow guide device of the shared air outlet flue of dwelling house adopts the bending tube shell structure, has air inlet coupling interface in the lower end of bending tube shell, can be matched with the anti-smoke blowing outlet valve of coupling type; One or many arc guide plates can be fixed in the inside of bending tube shell, make air-flow carry out the transition to straight up direction sleekly from substantially horizontal, reduce eddy resistance; The upper end of bending tube shell is the open type relief opening, does not have the parts of any change discharge directions, can not form air curtain in shared air outlet flue, has also thoroughly eliminated above-mentioned other drawback.As long as take off the anti-smoke blowing outlet valve of coupling type, just can easily the coupling type flow guide device be safeguarded and clean.
The utility model has the advantages that relief opening can not change discharge directions, prevent from effectively to form air curtain in the shared air outlet flue that be easy to safeguard and clean, and surface friction drag is little, exhaust is smooth and easy, the hygienic conditions in the holding chamber.
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Fig. 1 organigram of the present utility model;
Fig. 2 user mode schematic representation of the present utility model.
Embodiment one:
Shown in Fig. 1,2, coupling type flow guide device of the present utility model has water conservancy diversion bending tube shell 1, water conservancy diversion bending tube shell 1 has air inlet coupling interface 2 in the lower end that is positioned at indoor section, water conservancy diversion bending tube shell 1 has open type relief opening 4 in the upper end that is positioned at shared air outlet flue 7 parts of dwelling house.Water conservancy diversion bending tube shell 1 is that a bent angle is the bend pipes of 90 degree, and its inferior horn is the cambered surface wall of rounding off, has in the water conservancy diversion bending tube shell 1 to make the air-flow two arc guide plates 3 upwards of can slick and sly turning.The cross section of air inlet coupling interface 2 and open type relief opening 4 is square, and air inlet coupling interface 2 is vertical mutually with the center line of open type relief opening 4.Air inlet coupling interface 2 of the present utility model can be matched with the anti-smoke blowing outlet valve 5 of the coupling type of shared air outlet flue, and the anti-smoke blowing outlet valve 5 of coupling type is matched with the outlet pipe 6 of resident family gas outlet means.
Embodiment two:
Identical with embodiment one, just be provided with arc guide plate 3 in the water conservancy diversion bending tube shell 1.
