Abstract
The utility model discloses an airflow guiding non-return type combined fume exhausting channel which comprises a fume exhausting pipeline, wherein the side wall of the fume exhausting pipeline is fixed with a non-return valve through a fixing nut, the non-return valve is an elbow tubular non-return valve; an upward fume exhausting port of the non-return valve which is positioned in the fume exhausting pipeline is provided with an automatic non-return wind door; an air inlet of the non-return valve, which is connected with a gas outlet of an oil fume exhauster is positioned on the outside of the fume exhausting pipeline. The utility model has the advantages of simple structure, large gas exhausting quantity of the fume exhausting pipeline, smooth exhaust and thus the air quality in a room is sufficiently purified. Consequently, the environments of the living rooms of people are improved. Because the non-return valve uses a fixed form of a self nut, the non-return valve does not need be helped by other fittings. Consequently, the undamage of a pipeline wall is ensured. Meanwhile, the utility model is convenient for cleaning by taking off. A gas channel of the non-return valve is an arced bending pipe, and the sealing effect of the wind door of the non-return valve is good. Consequently, the mutual cross phenomenon and the back flow phenomenon of the exhaust gas of the oil fume are stopped.
Description
Technical field: the utility model relates to a kind of smoke discharging pipe, relates in particular to a kind of residence building and concentrates the air-flow guiding reverse-resistance type combination exhaust gas flue of getting rid of oil smoke.
Background technology:
Continuous increase along with living space, the increase gradually of smoke exhaust ventilator power, people are more and more higher to the air quality requirement of living environment, for the oil smoke in the kitchen, live dirty gas peculiar smell in chamber and the toilet etc., need emit in time by the fume centralized exhaust system.The pipe design of some present smoke discharging systems is two flues of major-minor, and auxillary flue is communicated with the room induced-draft fan and enters flue collector again, thereby its deficiency is:
1, volume is excessive, complex structure, and net sectional area is too small, and capacity is little and not smooth, and taint of odour smoke blowing and flue gas pour in down a chimney etc. between the user;
2, some smoke exhaust pipe is equipped with check (non-return) valve and prevents that flue gas from pouring in down a chimney, but the airflow direction in the check (non-return) valve gas outlet airflow direction that its smoke discharging system is adopted and the flue liquidates mutually, thereby weaken the flow velocity of air-flow in the pipeline, cause smoke evacuation smooth and sealing effect is poor, cause flue gas to pour in down a chimney.
Content invention: exist complex structure in order to overcome present residence building central exhaust pipeline, the problem of pouring in down a chimney easily when smooth and smoke evacuation are owed in smoke evacuation, the purpose of this utility model provide a kind of simple in structure, make easy to maintenance, capacity big, the exhaust gas flue of air-flow guiding reverse-resistance type combination smoothly of discharging fume.
The technical solution of the utility model realizes in the following manner:
A kind of air-flow guiding reverse-resistance type combination exhaust gas flue, it comprises on flue gas exhaust pipeline, the flue gas exhaust pipeline sidewall fixedly is equipped with check (non-return) valve by hold-down nut, check (non-return) valve is the syphon shape check (non-return) valve, the check (non-return) valve that the is positioned at flue gas exhaust pipeline exhaust opening that makes progress is equipped with automatic non-return air door, be positioned at flue gas exhaust pipeline outer be the check (non-return) valve air inlet that is connected with the lampblack absorber gas outlet.
Be positioned at and be connected with one below the outer check (non-return) valve of flue gas exhaust pipeline and connect the lubricating cup that connects of containing maimed oil that bend pipe condenses.
Automatic non-return air door is two semicircle air doors, and two semicircle air doors are positioned on the same axle, and these two ends are fixed on the bend pipe wall.
The check (non-return) valve exhaust opening external diameter that makes progress is 120-150mm, and along with the increase exhaust opening external diameter of number of floor levels increases progressively, air inlet is 150mm.
Good effect of the present utility model is:
1, simple in structure, the discharge duct capacity is big, and exhaust is unimpeded, and waste gas is fully discharged, and indoor air quality is fully purified, thereby has improved people's living environment greatly.
2, because check (non-return) valve adopts is self nut fixed form, need not by other accessory, the exhaust gas flue tube wall installs and fixes, thereby has guaranteed the excellent of duct wall, simultaneously, is convenient to take off cleaning.
3, the gas channel of check (non-return) valve is a curve bend, air inlet docks with the smoke exhaust ventilator exhaust duct in the horizontal direction, airflow direction is identical and straight up in gas outlet side and the pipeline, avoid with pipeline in air-flow liquidate and direction consistent, guarantee intrasystem residual oil smoke of exhaust gas flue or dirty gas, all can fully discharge.Because the obturation effect of check (non-return) valve air door is fine, goes here and there mutually and pour in down a chimney phenomenon thereby stopped oil flue waste gas.
Characteristics such as 4, flue gas exhaust pipeline is to adopt high-strength cement mortar, and the one-shot forming of alkali-free glass grid cloth has the intensity height, and is corrosion-resistant, and cost is low; Also can adopt pvc pipe or other high-strength temperature-resistant material to make.
5, check (non-return) valve can be made of materials such as high-strength fire-retarding plastics or PVC, install simple and convenient easily removable and washable, cheap, long service life.
Description of drawings:
Fig. 1 is a structural principle schematic diagram of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As seen from Figure 1: the utility model comprises on flue gas exhaust pipeline 1, flue gas exhaust pipeline 1 sidewall and by hold-down nut 3 check (non-return) valve is housed fixedly, check (non-return) valve is an elbow tubulose check (non-return) valve, and the check (non-return) valve that is positioned at flue gas exhaust pipeline 1 exhaust opening that makes progress is equipped with automatic non-return air door 2; Be positioned at flue gas exhaust pipeline 1 outer be the check (non-return) valve air inlet 4 that is connected with the lampblack absorber gas outlet.
It can also be seen that by Fig. 1, be positioned at be connected with below the outer check (non-return) valve of flue gas exhaust pipeline 1 one connect contain maimed oil that check (non-return) valve condenses connect lubricating cup 5.
Can be found out also that by Fig. 1 automatic non-return air door is two semicircle air doors, two semicircle air doors are positioned on the same axle, and these two ends are fixed on the bend pipe wall.
Operation principle of the present utility model is:
1), when smoke exhaust ventilator is in operate as normal, when oil smoke, dirty gas etc. pass through check (non-return) valve, two and the half garden shape air doors on check (non-return) valve top superimposed the opening that make progress automatically, make check (non-return) valve be in the state that opens fully, after the dirty gas of oil smoke changes the flow direction by check (non-return) valve, arrive in the exhaust gas flue smoothly, and the interior airflow direction of airflow direction and exhaust gas flue is identical, the waste gas that every layer of user discharged all leads to the gas flue top smoothly fully discharges.
2), when smoke exhaust ventilator quits work, two and half garden shape air doors on the check (non-return) valve are closed the check (non-return) valve current path because deadweight is supported by the inboard boss of bend pipe when the trend both sides separately drop down onto the level position.Make check (non-return) valve be in air-tight state, by the air communication mistake.Fundamentally stop smoke blowing, the taint of odour between family and family and poured in down a chimney the cigarette phenomenon.
3), this air-flow guiding reverse-resistance type combination exhaust gas flue is not subjected to outdoor wind direction, wind speed and Temperature Influence, is in negative pressure state in the pipeline all the time.
