Abstract
A down-draft bloc device for gas water heater includes a limiting bloc. The device also has technological features in an anti reverse flow plate, a positioning bloc and a shaft. The shaft is positioned on inner wall of the gas tube, the anti reverse flow plate connects to each other by means of the shaft, the positioning bloc is fixed on inner wall of the gas tube, the limiting bloc is arranged on inner wall of the gas tube and the length of the anti reverse flow plate is larger than that of the positioning bloc. The device can effectively isolate cold air from outdoor and the water heater, characterized by preventing the water heater from being frozen in cold weather and discharging gas and smoke out of the room while the water heater is in operation.
Description
Technical field: the utility model relates to a kind of anti-down wind apparatus of gas heater.
Background technology: forced-ventilated gas water heater is to discharge combustion product gases outdoor by smoke pipe, flue gas will be discharged to outdoor, and it is outdoor that smoke pipe has part to be installed in, but when water heater is not worked, under the colder situation of outdoor air, outside wind pressure is bigger, and cold air is directly blown to water heater the inside by smoke pipe, and this moment water heater this under idle state, the water pipe (copper pipe) of water heater the inside is full of water, when temperature was low, water freezing expanded, and causes water pipe from freezing crack.The anti-down wind apparatus of existing water heater is owing to the restriction of structure, and the ubiquity air leakage phenomena can not be blocked outdoor cold air.So when outside wind pressure is big, under the lower situation of air themperature, present smoke pipe does not have antifreeze preferably effect.The most anti-down at present wind apparatus has two kinds of forms: a kind of form is that anti-backflow plate, an off-centre are worn one, up and down a limited block structure arranged respectively; Another kind of form is that spacing block structure is opened, respectively had up and down to two blocks of anti-backflow plates, symmetry along the axle both sides.Contact and reserve the gap for fear of anti-backflow plate and tube wall, when outdoor when wind is arranged two kinds all leak out morely, outdoor cold air and water heater can't be isolated, do not have the effect of anti-freeze.For overcoming these defectives, the anti-down wind apparatus of gas heater is improved.
Summary of the invention: technical problem to be solved in the utility model provides a kind of anti-down wind apparatus of baffle plate of gas heater, it can be isolated outdoor cold air that is blown into and water heater effectively fully, avoid water heater frozen when outdoor temperature is low, and when water heater working, can discharge flue gas outdoor effectively.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises positive stop, anti-backflow baffle plate, positioning body, axle, described axle is fixed in the smoke pipe inwall, the anti-backflow baffle plate connects by axle, positioning body is fixed in the smoke pipe inwall, positive stop is fixed in the smoke pipe inwall, and the length of anti-backflow baffle plate is greater than the length of positioning body.
The length summation of anti-backflow baffle plate and positioning body is greater than the length of smoke pipe inwall.
Described positive stop cross section is round, polygonal, a bent limit shape.
It also is included in the anti-backflow baffle plate and the positioning body contact position is provided with the elevated-temperature seal bar.
The utility model is compared the beneficial effect that is produced with background technology:
1, because the utility model has adopted the anti-backflow baffle arrangement, so it can be isolated outdoor cold air that is blown into and water heater effectively fully, avoid water heater frozen when outdoor temperature is low, and when water heater working, can discharge flue gas outdoor effectively.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
The specific embodiment: shown in accompanying drawing 1, smoke pipe 1 is annular cylindrical body, anti-backflow baffle plate 4 can be two and more than, monolithic anti-backflow baffle plate 4 can be semicircular thin plate, the diameter of smoke pipe 1 is greater than the radius sum of two anti-backflow baffle plates 4, and the diameter of smoke pipe 1 is less than the summation of radius and two positioning bodies 5 of two anti-backflow baffle plates 4, the radius of two anti-backflow baffle plates 4 is greater than the length of positioning body 5, to guarantee that anti-backflow baffle plate 4 does not fall down, the flue gas air-flow that body 5 blocks that is positioned is less, and can live outdoor air-flow of coming by sealing ring, positive stop 2 can guarantee that anti-backflow baffle plate 3 can not make anti-backflow plate 3 translate into another side because of flue gas flow rate too soon, can't play anti-down wind action.Positive stop 2 can be little axle, also can be sheet, perhaps other shape, and anti-backflow baffle plate 3 is low weight, and there is enough gravity to fall down simultaneously and blocks the lower end of smoke pipe 1, and high temperature resistant, indeformable.Elevated-temperature seal bar 4 directly touch in anti-backflow baffle plate 3 contact position with positioning body 5, and when water heater was not worked, anti-backflow baffle plate 3 fell down, this moment two elevated-temperature seal bars good sealing function that contacted.
When water heater working, the flue gas that produces is pushed two anti-backflow baffle plates 3 open, and is outdoor through the smoke pipe discharge then, under the bigger situation of flue gas thrust, anti-backflow block 3 directly pushes up positive stop 2, so anti-backflow baffle plate 3 can only be movable back and forth between the two at them.When water heater is closed when not working, no flue gas process, anti-backflow this moment baffle plate 3 because the effect of gravity fall down from both sides because contact portion has sealing strip 4, so can better seal live the lower end of smoke pipe 1.When blast was arranged, the pressure of anti-backflow baffle plate 3 wind-engagings made its sealing better when outdoor.
