The technological scheme of the utility model is specific as follows: a kind of electronic rotation check valve for flue comprises:
Valve body is provided with oil extraction smoke pipe connecting end and is fixedly connected end with the body of wall flue;
Valve plate is arranged in the said valve body, is rotationally connected through bearing pin with said valve body;
Seal ring is arranged in the inner chamber of said valve body, in order to seal the slit between said valve plate and the said body cavity;
Motor is fixed on the said valve body, and is fixedly connected through rotating shaft and said valve plate; And
Close a position limit switch and open bit line journey switch, the two is 90 ° of phase differences and is located in the said valve body, and is electrically connected with the control circuit of said motor.
The said valve plate of the utility model is the doubling plate body structure, and said rotating shaft is clipped between the doubling plate body structure of said valve plate.
Said seal ring is double-deck oil-resistant rubber insert, and every layer of oil-resistant rubber insert contacts with wherein one deck plate body outer of said valve plate.
Said body cavity is cylindrical runner, and said valve plate is circular plate body.
Said motor is the permanent-magnet synchronous decelerator.
The utility model also can be connected to the motor case in said motor outer cup, and said motor case is fixed on the outer side surface of said valve body.
The utility model also can close a position limit switch and open bit line journey switch is installed in the switch box body with said, and said switch box body is arranged in the said valve body at valve plate rear portion.
The utility model utilizes the motor drives valve plate to rotate; Valve plate moves under driven by motor; Thereby can realize preventing the reliable sealing of check valve for flue effectively to have avoided the generation of oil smoke taint of odour situation in kitchen or the room in the oil smoke adverse current inlet chamber in the body of wall flue.The utility model is simple in structure, and is easy to install, good sealing effect, and valve is airtight reliable, is particularly suitable in the kitchen of returning the bigger high residential building building of cigarette blast, installing and using.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is a kind of circuit theory diagrams of the utility model.
Among the figure: 1, valve body, 2, valve plate, 3, seal ring, 4, the motor case, 5, motor, 6, the switch box body, 7, close a position limit switch, 8, open bit line journey switch, 9, rotating shaft.
Embodiment
With reference to figure 1, said valve body 1 is a hollow structure, and its inner chamber is cylindrical runner, and the two ends of said valve body 1 are opening respectively, and its left end is used to connect the oil extraction smoke pipe of range hood, and its right-hand member is used for fixing on gas exhaust duct.Said valve plate 2 is arranged in the said valve body 1, and is rotationally connected through bearing pin between the said valve body 1, and said valve plate 2 is circular doubling plate body structure.Said seal ring 3 is arranged in valve body 1 inner chamber, is used for when valve plate 2 sealings, sealing the slit between valve plate and the body cavity, and said seal ring 3 is double-deck oil-resistant rubber insert, and every layer of oil-resistant rubber insert closely contacts with the outer of wherein one deck plate body of said valve plate 2.
Said motor 5 is fixed on the said valve body 1, and is fixedly connected through rotating shaft 9 and said valve plate 2, rotates thereby when motor 5 rotates, drive said valve plate 2; Said rotating shaft 9 can be the output shaft of motor 5, or other rotating shafts of joining with output shaft.Said rotating shaft 9 is clipped between the doubling plate body structure of said valve plate 2.Said motor 5 outer cup are connected to motor case 4, and said motor case 4 is fixed on the outer side surface of said valve body 1.Said motor 5 can be the permanent-magnet synchronous decelerator.
The rear portion of valve plate 2 is provided with switch box body 6 in valve body 1, said position limit switch 7 and the open bit line journey switch 8 of closing, and the two is 90 ° of phase differences and is arranged in the said switch box body 6, and the two all is electrically connected with the control circuit of said motor 5.Particularly, with reference to figure 2, the said position limit switch 7 that closes is arranged on the circuit that motor 5 just changeing, and said open bit line journey switch 8 is arranged on the circuit of motor 5 counter-rotatings.A said position limit switch 7 and the open bit line journey switch 8 of closing, the two can be in the same level, also can be in the different plane height.
Whether said conducting of closing a position limit switch 7 and open bit line journey switch 8 receives the restriction of valve plate 2 rotational position; As shown in Figure 1, when valve plate 2 is in closed state, said closing stroke switch 7 conductings; Said open bit line journey switch 8 ends; When valve plate 2 is turned in the process of opening state by closed state, close a position limit switch 7 conducting still, open bit line journey switch 8 still ends; When said valve plate 2 turned to opening state (referring to the full open state, vertical when promptly the valve plate of this moment is with closed state), the said position limit switch 7 that closes ended, 8 conductings of said open bit line journey switch.
With reference to figure 2; Motor 5 can be realized forward or reverse under the control of clockwise and anticlockwise control switch K1, because the said position limit switch 7 that closes is arranged on the circuit that motor 5 just changeing, said open bit line journey switch 8 is arranged on the circuit of motor 5 counter-rotatings; Therefore when valve plate 2 turns to the closure or openness state; Saidly close a position limit switch 7 or 8 automatic cut-offs of open bit line journey switch, render electrical motivation 5 stops operating, so valve plate 2 has also stopped rotation.
Said clockwise and anticlockwise control switch K1 should be corresponding with the working state of range hood when control motor 5 rotates and reverse; That is: when range hood is worked; Said clockwise and anticlockwise control switch K1 control motor 5 is just changeing; When range hood quits work, 5 counter-rotatings of said clockwise and anticlockwise control switch K1 control motor.
The concrete working procedure of the utility model is following:
