Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, this Electronic control return air check-valve, comprise safety check base 6, safety check main part 7 and airduct external member 10, described safety check base 6 is arranged on common flue oil extraction mouth or range hood oil extraction mouth place, and safety check base 6 is fixed on its position by self tapping screw 1.One end of safety check main part 7 is connected in location fit with safety check base 6, and the other end of safety check main part 7 is connected with airduct external member 10 and forms vent passages; Safety check main part 7 is provided with motor cabinet 8, and motor cabinet 8 is fixedly connected with motor 13 by screw B9.The motor shaft of motor 13 is connected with one end of bent axle 12, and the other end of bent axle 12 is connected with the one end fits of rotating assembly B11, and the other end of rotating assembly B11 and one end of rotating assembly A5 are flat connectors structure; Valve block 4 while be fixed on the flat connectors of rotating assembly B11 by three screw A3, the another side of valve block 4 is fixed on the flat connectors of rotating assembly A5 by three screw D2, and three screw A3 and three screw D2 form stable triangle.Motor 13 driving crank 12 is also with moving valve plate 4 to rotate by rotating assembly B11, makes valve block 4 become plumbness or parastate with vent passages cross section or is the state of certain folding angle; Sensitive switch 14 is arranged on the below of motor 13 and is fixed on motor cabinet 8 by screw C15, and bent axle 12 is connected with sensitive switch 14 in movement process.
When motor receives range hood starting-up signal, by electrical control programming, motor 13 driving crank 12 drives rotating assembly B11, rotating assembly A5 and valve block 4 half-twist, makes valve block 4 and vent passages cross section orthogonal, make safety check resistance minimum, reach Maximum Ventilatory Volume.When motor 13 receives range hood air amount variable signal, by electrical control programming, motor 13 driving crank 12 drives rotating assembly B11, rotating assembly A5 and valve block 4 to adjust the folding angle of valve block 4 according to the change of range hood air quantity size.When motor receives range hood off signal, by electrical control programming, motor 13 driving cranks 12 drive rotating assembly B11, rotating assembly A5 and valve block 4 counterrotating, touch sensitive switch 14 and stop operating, and close safety check.
Working mechanism of the present utility model: because Electronic control return air check-valve adopts drive and control of electric machine, rotation torque is comparatively large, can effectively avoid valve block valve block cannot to be opened because of greasy dirt viscosity, or the problem such as cannot to close because outside suction is excessive; When range hood is opened, the valve block of Electronic control return air check-valve is mutually vertical with ventilation section, effectively can alleviate range hood and hinder in discharge oil smoke process, also reduce the loss of pressure simultaneously, also improve the ability of oil extraction of cooker hood simultaneously; After range hood is opened, when changing air force, Electronic control return air check-valve can according to the air quantity of range hood change, adjust the folding angle of safety check valve block accordingly, change its vent area, it is made to reach energy-saving and emission-reduction, anti-air-return effect, automatically regulate change with range hood joint control simultaneously, embody the intellectuality of integrated product.
Of the present utility modelly to install and use:
1. want after part combination firmly, steadily, must not the problems such as distorted deformation be had;
2. motorized non-return valve closedown and under 300Pa pressure, without obvious gas leak phenomenon, leakage rate is not more than 2%;
3., after complete machine has been assembled, should connect firmly, open and close flexibly.Each rotary part answers stability of rotation, without blocking and colliding;
4. motorized non-return valve is after opening completely, and valve block 4 should perpendicular to vent passages cross section, and after closing completely, valve block 4 should be parallel to vent passages cross section;
5. motorized non-return valve is in operating temperature range, under the operating pressure differential that indicates, continuous operation and do not affect the normal work of its tightness and drive unit.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
