Description

The anti-speed change system device of exhaust gas flue five
Technical field
It is the anti-speed change system device of exhaust gas flue five specifically the present invention relates to exit flue.
Background technology
" the anti-air bleeding valve of pressure swing type five " is installed on kitchen and bath's exhaust duct air inlet, completes aerodynamics Bernoulli equation institute table The internal fluid dynamic pressure and the conversion of static pressure stated are realized at five anti-air bleeding valve air inlets, make not open fume exhauster for kitchen or exhaust Air inlet formation negative pressure or static pressure under fan-shaped condition reduce;Open and produced at the air inlet under fume exhauster for kitchen or exhaust fan situation Jet, makes to form negative pressure in pipeline or static pressure reduces.Smoke evacuation tolerance is effectively increased, prevents flue gas from pouring in down a chimney.
(the applying date of patent document 00222427.5:2000.03.03 a kind of exhaust gas flue) is disclosed, is included logical into cigarette Road, smoke-outlet flue and the automatic valve being arranged in housing, it is characterised in that:Flue gas cut-off equipment is provided with fume inlet passage. The utility model has the advantages that simple in construction, manufacturing cost is low, easy for installation, temperature tolerance is strong and service life is long, and it can be with Effectively prevent the backflow of cooking fume, because using five prevent light body wallings make it have intensity height, light weight, fire prevention, waterproof, prevent open Split and the features such as anti-aging.
(the applying date of patent document 201210081247.1:2012.03.26) disclose one kind and automatically adjust exhaust air rate oil extraction Flap is set in flue gas fire-preventing check valve, including valve body, valve body, and flap is in turnably to be sleeved on fixed mandrel, mandrel The upper preceding spring of suit, rear spring, set the flap head part being sleeved on mandrel, flap head part and fixation between preceding spring and rear spring Fuse link connection;The oil smoke vent hole for communicating, being opened and closed by the movable of flap with fume pipeline is set on valve body.This hair It is bright rational in infrastructure, favorable working performance;When lampblack absorber does not work, flap is in the state for closing valve channel;Lampblack absorber works When, cooking fume drives flap to rotate and be moved rearwards by, by cooking fume throughhole portions or fully open, while playing centrifugation to oil smoke Effect, increases working effect.The aperture of oil smoke vent hole is related to oil smoke acc power.
In summary, existing pressure swing type gas flue is used component for variable-pressure and diversion component, its structure design are present such as Lower defect:Component for variable-pressure and diversion component are separately mounted on two of exhausting duct or three tube walls, may due to installing positioning The error of generation, can influence exhaust effect, also be inconvenient to install;Meanwhile, the air-flow risen in exhausting duct has logical from transformation venturi Cross, also there is what is passed through from the gap between diversion component, component for variable-pressure and duct wall, multiply air-flow different in flow rate collects, Turbulent flow is produced, exhaust effect can be also influenceed.Most of gas flues are blank pipes in the market, without guiding device, it is easier to shape Into phenomenons such as gas leakage smoke leaking bunch tastes.
The content of the invention
The present invention seeks to aim to provide a kind of attach together transformation, air inducing, non-return, fire prevention to be integrated, exhaust effect is good The anti-speed change system device of exhaust gas flue five.
To realize above-mentioned technical purpose, the technical solution adopted by the present invention is as follows:
The anti-speed change system device of exhaust gas flue five, including housing, the housing include speed change side, air intake side, activity Top cover, the air intake side is provided with the air inlet for being used for connecting exhausting duct, and the case top is provided with air outlet, the housing Wall is communicated with the air-inducing passage of air inlet and air outlet, and the air-inducing passage is spout shape, and its air inlet opening bore is more than Air outlet opening bore, the lower housing portion is divided into cone, and the lower housing portion point upper end cross-sectional openings bore is more than lower end Cross-sectional openings bore, the lower housing portion point bottom is provided with oil holding slot, and the housing upper is divided into round platform, the housing upper Upper end cross-sectional openings bore is divided to be less than lower end cross-sectional openings bore, the housing upper point top is provided with non-return structure;Institute State the first connection sheet that non-return structure includes being used to connect removable top cover, the second connection sheet for connecting speed change side, the 3rd Connection sheet, the 3rd connection sheet is L-shaped, and its top both sides is provided with the first journal stirrup, and first journal stirrup is provided with first rotating shaft, The 3rd connection sheet bottom is fixedly connected with the second connection sheet by the first bolt, and the 3rd connection sheet top passes through first turn Axle is flexibly connected the first connection sheet, and first connection sheet passes through the second bolt connection removable top cover.
Reverse-filling is easy to implement using non-return structure, anti-taint of odour, anti-smoke blowing, anti-flare is returned and altered, flue gas backflow.
Further limit, the removable top cover is provided with the U-shaped adjustment hole for being used for inserting the second bolt.
