Abstract
The utility model relates to a forced non return valve. The utility model comprises an exhaust gas inlet, a valve body and an exhaust gas outlet, wherein, a fan and a flow distribution plate are installed on the valve body, and one end of the flow distribution plate leads to the center of the exhaust gas inlet and the center of the exhaust gas outlet. The utility model has a simple structure and adopts cone valve non return technology and gas forced drainage exhaustion technology, the utility model efficiently solves the problems of a gas water heater during the centralized exhaust of exhaust gas, and the problems are that the exhaust of the exhaust gas is obstructed and the exhaust gas pours inversely; security in the application of the gas water heater is improved, the utility model provides possibility in greatly reduce the cross-section area of centralized exhaustsmoke pipelines, and thus, the effective utilization area of a building is raised; the utility model is a fire-new exhaust non return valve.
Description
The utility model relates to a kind of check valve, and particularly a kind of residential housing coal gas shower waste gas that is applicable to is concentrated the check valve of discharging.
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-positive drive 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, is characterized in that: fan and flow distribution plate are housed on the described valve body, and flow distribution plate and valve body are at fan and go out to form between the exhaust outlet and force the drainage air channel; 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 gas to force drainage air draft and the non-return technology of 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.
Fig. 2 is a side view of the present utility model.
The utility model comprises into exhaust outlet 2, valve body 8, goes out exhaust outlet 6, it is characterized in that: fan 3 and flow distribution plate 1 are housed on the described valve body 8, one end of flow distribution plate points to the center into and out of exhaust outlet, and valve body is at fan with go out to form between the exhaust outlet and force the drainage air channel; Describedly go out the cone valve 5 that lifting opens and closes is housed on the exhaust outlet 6,, can effectively stop the waste gas that is emitted on flue to indoor anti-filling when cone valve cuts out elbow; Guide plate 4 also is housed, to help the smooth discharge of waste gas on valve body 8; Back at valve body 8 is installed base plate 7 in addition, installs and adopts dovetail groove to inlay between base plate and the valve body, guarantees the sealing between valve body and the installation base plate.
When using the utility model, open fan 3, blast is opened cone valve 5 by the pressure drainage air channel that forms between flow distribution plate 1 and the valve body, form and force the drainage air-flow,, be subjected to the effect of drainage air-flow when waste gas enters valve body 8 by advancing exhaust outlet 2, the waste gas ejectment is gone out out exhaust outlet 6, enter flue; Close fan 3 when gas hot-water apparatus quits work, cone valve 5 this moment auto-closing under the effect of gravity makes the waste gas in the flue can not instead pour into indoor.
