Abstract
The utility model relates to a drainage non return valve which comprises an exhaust gas inlet, a valve body, and an exhaust gas outlet, wherein, a fan and a drainage tube are installed on the valve body, one end of the drainage tube is communicated with the fan, the other end of the drainage tube is communicated with the exhaust gas outlet, and a cone valve which can be lifted, lowered, opened and closed is installed on the exhaust gas outlet. The utility model has the advantages of novel design and simple structure; gas drainage and cone valve non return technology is adopted, and the problems of a gas water heater that the exhaust of the exhaust gas is not fluent and the exhaust gas pours inversely during the centralized exhaust of exhaust gas are effectively solved; security during the application of the gas water heater is improved, the utility model provides possibility in largely reducing the cross-section area of a pipeline used for exhausting the centralized exhaust gas, and thus, the effective utilization area of a building is enlarged. The utility model is a fire-new exhaust non return valve.
Description
The utility model relates to a kind of check valve, particularly a kind of check valve that is applicable to the toxic emission of residential housing coal gas shower.
The general at present gas hot-water apparatus that uses has two kinds: balanced type and flue type.Wherein the waste gas of flue type gas hot-water apparatus will be by flue to outdoor discharging, but because the exhaust gas pressure of discharging is very little, exist the not smooth problem of exhaust, the waste gas that contains carbon monoxide of its discharge is also instead irritated in the room easily, causes that personnel are poisoned to death in the chamber.For this reason, when requiring the nature discharging, the sectional area of central exhaust pipeline must guarantee greater than 0.5 square metre, though improved the exhaust gas discharging situation like this, but caused the effective utilization area of building to descend, the plane figure difficulty, and can't tackle the problem at its root.
The purpose of this utility model provides a kind of smooth discharging that can guarantee waste gas, can guarantee to discharge the waste gas of smoke inlet flue again not to the anti-drainage type check valve of irritating in other room.
Task of the present utility model is achieved in that the utility model comprises into exhaust outlet, valve body, goes out exhaust outlet, and it is characterized in that: fan and drainage tube are housed on the described valve body, and an end of drainage tube leads to fan, and the other end leads to exhaust outlet; Going out also to be equipped with on the exhaust outlet cone valve that lifting opens and closes.
The utility model is novel, simple in structure, adopted the non-return technology of gas drainage and cone valve, the waste gas that has solved gas hot-water apparatus is effectively concentrated the not smooth and anti-problem of irritating of waste gas of exhaust in the discharging, improved the Security that gas hot-water apparatus uses, and for the sectional area that reduces the central exhaust pipeline significantly provide may, thereby effective utilization area of building is risen, and is a kind of brand-new exhaust check valve.
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
The utility model comprises into exhaust outlet 7, valve body 4, goes out exhaust outlet 2, and it is characterized in that: fan 5 and drainage tube 8 are housed on the described valve body 4, and an end of drainage tube leads to fan 5 the other ends and leads to exhaust outlet 2.End at drainage tube 8 has the wind collection scoop 6 that is contraction-like; The regulating valve 9 of adjustable drain air quantity also is housed in the described drainage tube 8; Describedly go out the cone valve 1 that lifting opens and closes is housed on the exhaust outlet 2, when cone valve cuts out, can effectively stop the waste gas that is emitted on flue to indoor anti-filling; Guide way 3 also is housed, to help the smooth discharge of waste gas on valve body 4.
When using the utility model, open fan 5, blast is opened cone valve 1 by drainage tube 8, forms the drainage air-flow, when waste gas enters valve body 4 by advancing exhaust outlet 7, is subjected to the effect of drainage air-flow, and the central exhaust pipeline is gone in the waste gas ejectment; Can adjust regulating valve 9 according to the size of exhausted air quantity simultaneously, it is adapted.Close fan 5 when gas hot-water apparatus quits work, cone valve 1 this moment auto-closing under the effect of gravity makes the waste gas in the flue can not instead pour into indoor.
