Abstract
The utility model relates to a vertical 1 axial flow exhaust fan which comprises a motor, a motor bracket, a bearing, a casing, a transmission shaft and an impeller. The utility model is characterized in that the casing is connected with a valve seat; an air inlet and an exhaust outlet are arranged on the casing; the motor which is arranged above the casing is connected with the impeller through the transmission shaft of which the outer side is sheathed with a sleeve pipe; a check valve can move up and down along the sleeve pipe and is matched with the valve seat. Because the check valve is matched with the line of the valve seat, the utility model has the advantages of good sealing effect and large air displacement, and the utility model can be used in inflammable and detonable occasions.
Description
The utility model relates to air bells conditioner, particularly a kind of vertical axial-flow ventilating fan.
In the workshop of the kitchen of dwelling house, cultural place, factory, watch some places of supporting on canopy and the steamer, generally take a breath with the horizontal ventilating fan, when the gas fan is not worked, in order to prevent to be provided with the louvre type non-return device in the reverse inlet chamber of gas on ventilating fan, this louvre type non-return device is because poor sealing, at cold area, the check effect is Cui not, because motor is installed on the air-flow path with impeller, is not suitable for using in inflammable, explosive occasion in addition.
The vertical axial-flow ventilating fan that the purpose of this utility model provides a kind of good sealing effect, can use in inflammable, explosive occasion.
The utility model is to realize like this, it comprises motor, electric machine support, bearing, housing, transmission shaft and impeller, it is characterized in that housing is connected with valve seat, have suction port and relief opening on housing, the motor that is arranged on housing top is with sleeve pipe by the outside transmission shaft is connected with impeller, and check valve can move and cooperates with valve seat along sleeve pipe is upper and lower.The utility model has good sealing effect because check valve cooperates with the valve seat line, and the advantage that air displacement is big can also be used in inflammable, explosive occasion.
Below in conjunction with accompanying drawing the utility model is further described,
Fig. 1 is the structural representation of vertical axial-flow ventilating fan,
Fig. 2 is the A--A diagrammatic sketch of Fig. 1,
Fig. 3 is the schematic representation of impeller,
As Fig. 1--shown in 3, this vertical axial-flow ventilating fan comprises motor 1, electric machine support 2, bearing 3, housing 4, transmission shaft 5 and impeller 6, housing 4 is connected with valve seat 7, have suction port 8 and relief opening 9 on housing 4, the motor 1 that is arranged on housing 4 tops is with sleeve pipe 10 by the outside transmission shaft 5 is connected with impeller 6, and sleeve pipe 10 is by bearing 3 supportings that are arranged on housing 4 and the valve seat 7, check valve 11 can be along on the sleeve pipe 10, following motion also cooperates with valve seat 7, when electric motor starting, the axial flow pressed gas that is formed by impeller 6 rotations rises check valve 11, and gas is discharged from relief opening 9; When motor stopped, check valve 11 fell and the valve seat fitted seal by deadweight.
Claims (2)
1, a kind of vertical axial-flow ventilating fan, it comprises motor, electric machine support, bearing, housing, transmission shaft and impeller is characterized in that housing is connected with valve seat, has suction port and relief opening on housing, the motor that is arranged on housing top is with sleeve pipe by the outside transmission shaft is connected with impeller, and check valve can move and cooperates with valve seat along sleeve pipe is upper and lower.
