Description
Technical field
The utility model relates to a kind of unidirectional venting gas appliance, relate in particular to a kind of be used for all kinds of dwelling houses effectively prevent collaborate mutually between the air outlet flue, smoke blowing and help the flow-guiding non-return exhaust valve that flue gas is discharged swimmingly.
Background technique
Present all kinds of dwelling houses all use shared air outlet flue, and each resident family enters indoor flue gas main pipe, concentrates from the outlet port on roof and discharge by the suction port on the main pipe, yet the flue gas of lower floor can enter in the room from the suction port of upper strata resident family in last row's process, when wind was big, the anti-indoor phenomenon of going into resident family of lower floor of flue gas that upper strata resident family discharges also can appear.For many years, those skilled in the art is seeking the way of various solutions always, for example: utility model patent 98225105.X discloses a kind of filtering type check valve, it comprises pipeline, fixing frame, on the suction port of pipeline, be provided with filter screen, the air outlet of pipeline is an inclined-plane, the check sheet that has at least a slice to cooperate on the inclined-plane with the inclined-plane, and the upper end of check sheet has rotating shaft to be connected with axle sleeve on the inclined-plane, pipeline air outlet.This filtering type check valve owing to be provided with filter screen, causes oil smoke to be suspended on the wire side, makes that the air draft effect is undesirable.Utility model patent 99239938.6 discloses a kind of eccentric check valve, it comprises base, valve body, be respectively equipped with intake grill and exhaust outlet in two ends of valve body, eccentric valve plate is housed on described exhaust outlet, the position of eccentric valve plate rotating shaft is above the center of exhaust outlet.This eccentric check valve between valve plate and the exhaust outlet, rotates around the axis because of needs keep valve plate, thus must be gapped between the endoporus of the cylindrical of valve plate and exhaust outlet, poorly sealed; If by the end face seal of valve plate, then the valve plate left surface of rotating shaft top and exhaust outlet interior edge face seal, and the valve plate below the rotating shaft, therefore also can not seal sternly because of valve plate has thickness by the exterior edge face sealing of right flank and exhaust outlet; Therefore flue gas also can take place go into indoor phenomenon by the gap is counter.And, the most important thing is two above-mentioned utility model patents, its valve block all is upper end hinged securement, the valve shaft of the lower end of valve block around the upper end upwards rotates to be opened, yet under the effect of wind-force, the maximum open degree of valve block is difficult to reach parallel with horizontal plane, has reduced effective discharge area of valve body, therefore hinders upwards discharging of flue gas.
An inventor utility model patent ZL94200748.4 formerly discloses the anti-device of collaborating of a kind of high-rise building common exhaust duct, this device is made up of main pipe wall jet pipe and the unidirectional check valve of heavy hammer type, the unidirectional check valve of heavy hammer type wherein also is a kind of flow-guiding non-return exhaust valve, the complex structure of this check valve, the inventor is on the architecture basics of this valve, and constantly a kind of simple in structure, valve block return novel exhaust valve is freely designed in research and development.
