Compared with the prior art, the ventilating duct gas partition device can seal the ventilating duct when ventilation is not required, so as to have effects of eliminating gas backfilling and gas odor tainting in an exhaust system and cutting off air pollution and bacterial transmission, and has the advantages of working stably and reliably and saving energy consumption.
Description
Technical field
The utility model relates to a kind of ventilation shaft, more specifically to a kind of ventilation shaft gas partition apparatus.
Background technology
Along with improving constantly of living standards of the people, the air quality in the building is also grown with each passing day, stop gas extraction system gas and recharge, scurry flavor, cut off air pollution and spread of germs is the problem that must solve.Existing building building, the most employing concentrates the form of exhaust that exhaust is carried out in toilet, kitchen, promptly be responsible for the shared exhaust of position user, there is big shortcoming in this exhaust form: reach certain pressure or building terrace air-flow and change direction in the main exhaust pipeline, the capital causes that gas recharges, scurries the flavor phenomenon in the pipeline, and architecture indoor is caused air pollution, easily produces legion's property spread of germs.
And existing exhaust equipment, the simpler and cruder mode of general employing mostly is passive loose-leaf structure greatly, can't solve gas and recharge this problem.Passive loose-leaf structure, what adopt is the method that simple mechanical type cuts off, add a plastics sideboard in the outlet side of exhaust fan, utilize exhaust fan to get rid of air-flow and strut baffle plate, close plastic dam when exhaust fan and freely fall after rise, must stay 5-6mm Peng at the baffle plate periphery owing to will utilize air-flow to promote sideboard, baffle plate weight is lighter in addition, the air-tightness of closing is relatively poor, can't stop gas extraction system gas at all and recharge, scurries flavor, cuts off air pollution and spread of germs.
As Chinese patent literature CN2427771 " Scavenger fan ", the Scavenger fan that use in a kind of kitchen, lavatory etc. is disclosed, it is that the fan shell of existing Scavenger fan is made cylindrical shell fan shell, install motor, flabellum, movable louvre blade, cylindrical shell fan shell inner termination is connected and fixed the exhausting exhaust shroud by bolt and nut, cover connects the exhausting blast pipe and forms again, to kitchen, the lavatory that keeps clear of skin, window, has good exhausting exhaust effect.But, the Scavenger fan of this structure, employing be the method that simple mechanical type cuts off, can't be when not needing to ventilate the effective closure ventilation shaft, stop gas extraction system gas and recharge, scurry flavor, cut-out air pollution and spread of germs.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of ventilation shaft gas partition apparatus is provided, can be when not needing to ventilate the enclosed ventilation pipeline, the technical scheme of employing is as follows:
Ventilation shaft gas partition apparatus of the present utility model, it is characterized in that: comprise housing, be located at baffle plate, sealing plate in the housing, have air vent in the housing, baffle plate is installed on the housing madial wall at air vent middle part, have at least one air-vent on the baffle plate, sealing plate is provided with the diaphragm seal that can be used to the sealing baffle air-vent, leave the space between the adjacent seals sheet, this is when ventilating for needs, space and air-vent overlap, and can ventilate, and described sealing plate is provided with control lever, control lever passes the sliding tray of housing, stretches out outside the housing.When not needing to ventilate, by control device or manually-operated control lever, make sealing plate move, diaphragm seal is blocked the baffle plate air-vent; When needs ventilate, by control device, make sealing plate move, diaphragm seal is removed, and no longer blocks the baffle plate air-vent, this device can be directly and exhaust equipment use synchronously.
In order to improve ventilation, the cross section at baffle plate place, described air vent middle part is bigger than the cross section at air vent two ends.Like this, the size of the air-vent that can ventilate on the increase baffle plate that can try one's best effectively improves ventilation.
In order further to improve ventilation, described baffle plate is conical surface-shaped, and the bottom increases the width of air-vent gradually from the baffle plate top to baffle plate on the baffle plate.
For the ease of making, described housing is made up of procapsid and back casing.
The utility model beneficial effect against existing technologies is, since can be when not needing to ventilate the enclosed ventilation pipeline, therefore can play and stop the effect that gas extraction system gas recharged, scurried flavor, cut-out air pollution and spread of germs, and working stability is reliable, the saving energy.
