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, the unidirectional water conservancy diversion venting gas appliance that is used for the residence discharge road of smoke blowing.
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 because check valve is being deposited error in processing with in installing, often causes valve block to be not closed completely, owing to be provided with filter screen, causes oil smoke to be suspended on the wire side simultaneously, 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.
The content of invention
The purpose of this utility model is to overcome the deficiency of technique scheme, solves better that the smokejack suction port is poorly sealed, the problem of smoke blowing gas, and a kind of novel unidirectional water conservancy diversion venting gas appliance that is used for the residence discharge road rational in infrastructure, simple is provided.
To achieve these goals, the technological scheme that the utility model adopted is: a kind of unidirectional water conservancy diversion venting gas appliance that is used for the residence discharge road, it comprises one-way exhaust valve, the housing that this one-way exhaust valve comprises, be provided with valve block and be used for the valve block framework that is inclined to set that valve block is fitted in described housing, the rotating shaft at described valve block top is located in the mounting hole of valve block framework upper end rotationally; It is characterized in that: be loose spacious the cooperation between the rotating shaft of described mounting hole and valve block.
That described mounting hole is that cross section is is fan-shaped, oval, circular, rectangle or polygonal any through hole shape.
Described valve block framework and valve block are to the exhaust outlet direction to tilt from top to bottom, and tilt angle γ is that 40 degree are to 80 degree.
The cross section that is shaped as of described housing is square, rectangular, polygonal, circle or oval any hollow tubular; And the entrance point of described housing further is provided with the circular interface that is connected with the exhaust duct of air bells exhauster.
The outlet end of described one-way exhaust valve housing takes the form of inclined plane, and is provided with flow-guiding non-return exhaust valve at this outlet end; This flow-guiding non-return exhaust valve comprises valve block, and the bottom of housing outlet end is located in the rotating shaft of described valve block lower end rotationally, and also is provided with limit stoper or/and returning device at the valve block place.
The angle α of the outlet end of described housing and horizontal plane is the 30-80 degree.
When independent use limit stoper, the position of described limit stoper makes the maximum opening angle β of valve block for less than 90 degree and greater than the α angle.
When using limit stoper and returning device simultaneously, it is less than 170 degree and greater than the α angle that the position of described limit stoper makes the maximum opening angle β of valve block.
Described limit stoper is a kind of in the following structure: be located at the restriction protrusion in the main pipe; Be located at the spacing push rod on the valve block outer side surface; Be located at the limiting stopper of the outer side surface bottom of valve block; Be located at the spacing pole that is kink shape of lower end, the valve block outside; Be located at lower end, the valve block outside and be the limited ring of crooked ring-type; One end is fixed on the housing outlet end end top, the other end and is the positive stop hook that hook-shaped hook is held in the top of valve block; Be located at the spacing backguy between valve block inboard and the housing; Perhaps be: the end has the limit pull rod of projection and is located at the interior framework of housing, is provided with in the middle of the framework and makes the intransitable slotted hole of described projection, and an end of limit pull rod is fixed in the inboard of valve block, and the end of another band projection is at the opposite side of the slotted hole of framework.
A kind of in the following array structure of described returning device: the weight that is located at the valve block inboard; Be located at the return elastic component of valve block inboard: spring or elastic caoutchouc rope; Be located at the pressure spring in the valve block outside.
Owing to take said structure, be located at the outlet valve of suction port, this outlet valve adopts the valve block framework of inclination, the rotating shaft of its valve block is adopted cooperating of big spacious amount with mounting hole, valve block is under the situation of the constraint that is not subjected to mounting hole, rely on the effect of its gravity to be fitted in fully on the acclivitous end face of valve block framework, thereby solved the deviation that causes owing to processing and alignment error, and then the problem that causes valve block to be not closed completely.The outlet of housing simultaneously is provided with flow-guiding non-return exhaust valve, and the bivalve acting in conjunction has increased sealing effect, and from as can be seen above-mentioned, structure of the present utility model is more reasonable, and is simple in structure, sealing is tighter, anti-smoke blowing gas better effects if.
