Specific embodiment
The present invention is illustrated with reference to the drawings and specific embodiments:
As shown in Figure 1, a kind of opposite-flushing type whirlpool rear exhaust apparatus, the exhaust apparatus has the exhaust whirlpool of upper surface opening
Shell 1；The bottom surface of exhaust volute 1 is provided with the partition 6 exit casing internal cavities to be divided into two inner cavities；It is described
The corresponding two side walls of exhaust volute have the pit being recessed inwardly, and the bottom surface of the pit has and is vented inside volute
The through-hole that cavity is connected；Through-hole on two pits is connected with inner cavity described in two respectively；Setting in the pit
There are bellows 3, and the protrusion of bellows 3 and corresponding pit；The both ends of the bellows 3 are respectively arranged with installation
Flange 7；The both ends of the bellows 3 stretch out mounting flange 7 respectively and have outside flange in its end；The bellows 3
The outer diameter of both ends flange is less than the inner edge of Method for Installation flange aperture；The flange at 3 both ends of bellows had not only prevented flange in axial abjection, but also can
To guarantee to guarantee with the sealing between phase accessory simultaneously because there is certain interval between flange and bellows as gasket seal
Flange can be rotated freely circumferentially；The bellows can not only compensate the error that assembly generates, but also zero absorbable
The heated expansion of part additionally is able to absorb the displacement that components vibration generates；The center of the bellows 3 have with it is corresponding
