Abstract
The utility model belongs to the technical field of check valves, and particularly relates to a check valve of a range hood. The valve is characterized in that a valve body, a valve sheet, an air inlet and an air outlet are included, wherein a valve body inner ring is arranged on the inner side of the valve body, and the valve sheet is hinged and matched with the valve body through a turning block. The check valve of the range hood has the advantages that the valve sheet and the valve body are hinged and matched with each other, so that when not in use, the valve sheet can be in contact with an inclined air outlet end surface of the check valve inner ring under the gravity to avoid recharge; an outer ring of the valve sheet is connected with a sleeve gasket in a sleeved manner, so as to achieve effective sealing; and the seal ring can be replaced when oil fume is accumulated after a long-time use of the valve, thereby achieving simple and convenient cleaning and maintenance of the range hood.
Description
Technical field
The utility model is non-return valve technology field, is specifically related to a kind of kitchen ventilator safety check.
Background technique
It is the rotating shaft that is provided with vertical and horizontal in the valve air-flow path mostly that the safety check of discharging fume in the technology is arranged now, rotating shaft is in use for some time easily clung by greasy dirt, cause rotation dumb, and cleaning solution inconvenience, the kitchen ventilator that has is to rely on two blades on the safety check to cover exhaust outlet, thereby reach the effect that prevents return air, but owing to service time of a specified duration influence sealing effect to have produced very big gap between rear blade and the safety check, peculiar smell outside being etc. enters the kitchen, influences people's life.
The model utility content
At problems of the prior art, the purpose of this utility model is to provide a kind of technological scheme of kitchen ventilator safety check, can effectively stop oil smoke etc. to recharge, and is also simple and convenient when changing valve block.
Described kitchen ventilator safety check is characterized in that comprising valve body, valve block, suction port and air outlet, and the valve body inboard is provided with the valve body inner ring, and valve block cooperates by moving block and valve body are hinged.
Described kitchen ventilator safety check is characterized in that riveted joint of described valve block and moving block or threaded.
Described kitchen ventilator safety check is characterized in that the outer ring socket seal ring of described valve block.
Described kitchen ventilator safety check is characterized in that the end face of giving vent to anger of described valve body inner ring is a leaning structure.
Described kitchen ventilator safety check is characterized in that the end face of giving vent to anger of described valve body inner ring is a leaning structure, and valve block is that face contacts with the end face of giving vent to anger of valve body inner ring.
Above-mentioned kitchen ventilator safety check, valve block cooperates with valve body is hinged, the time spent does not make the valve block and the inclination of the safety check inner ring end face of giving vent to anger contact under action of gravity, avoid recharging,, can effectively play the effect of sealing simultaneously at valve block outer ring socket stuffing box gland, of a specified duration when service time, when oil smoke gathers, only get final product with changing a seal ring, make like this kitchen ventilator cleaning and safeguard simple and convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a sectional drawing of the present utility model.
Among the figure: 1-valve body, 2-valve block, 3-air outlet, 4-valve body inner ring, 5-suction port, 6-moving block, 7-seal ring.
Embodiment
Now the utility model is described in further detail in conjunction with Figure of description:
As Fig. 1, shown in 2, the kitchen ventilator safety check, comprise valve body 1, valve block 2, suction port 5 and air outlet 3, oil smoke enters safety check from suction port 5,3 discharge from the air outlet, valve body 1 inboard is provided with valve body inner ring 4, and the end face of giving vent to anger of valve body inner ring 4 is a leaning structure, and valve block 2 is that face contacts with the end face of giving vent to anger of valve body inner ring 4 under action of gravity, can stop oil smoke to recharge, valve block 2 is by moving block 6 and 1 hinged cooperation of valve body, when oil smoke is discharged, with valve block 2 jack-up, get rid of oil smoke, its middle valve plate 2 is riveted with moving block 6 or is spirally connected, and the outer ring socket seal ring 7 of valve block 2 can effectively increase tightness, of a specified duration when service time, when oil smoke gathers, only get final product, make that like this operation and maintenance of kitchen ventilator is convenient succinct with changing seal ring 7.
The utility model is not limited to the foregoing description, does various distortion or applies mechanically all within this technological scheme protection domain according to the foregoing description.
