Specific implementation mode
Below in conjunction with attached drawing and the embodiment provided, the present invention is further illustrated, and however, it is not limited to this.
As shown in Figure 1, a kind of overall plastic exhaust structure of power electronic product, including insulation inlet suction port 1, insulation float 2,
Insulate valve cylinder 3 and insulation air outlet adapter 4, it is described insulation valve cylinder 3 both ends respectively with insulation inlet suction port 1 and insulate air outlet adapter
4 are tightly connected, and the insulation float 2 is located in the inner cavity of insulation valve cylinder 3, and the one end for the float 2 that insulate and insulation inlet suction port 1
The axial connecting hole 11 being equipped with has clearance fit, the insulation air outlet adapter 4 to have axial venthole 41, the insulation float 2
Density be less than water density.
As shown in Figure 1, in order to ensure the good airproof performance of insulation inlet suction port 1 and insulate air outlet adapter 4 and the floating drum 3 that insulate,
There is the insulation inlet suction port 1 first tapered thread linkage section 12, insulation air outlet adapter 4 to have the second tapered thread linkage section
42, the both ends of the insulation floating drum 3 are respectively equipped with conical screw hole, and the first tapered thread linkage section 12 and the second tapered thread
Conical screw hole of the linkage section 42 respectively with the both ends of insulation floating drum 3 is tightly connected.
In order to further increase the leakproofness of the present invention, the first tapered thread linkage section 12 and the second tapered thread connect
The periphery for connecing section 42 is equipped with unsintered tape.Certainly, it is not limited to this, it can be also respectively equipped with two weeks of tapered thread linkage section
The leakproofness that sealing ring improves insulation inlet suction port 1 and insulate between air outlet adapter 4 and the floating drum 3 that insulate.
In order to ensure tapered thread linkage section end with insulation floating drum 3 end combined it is even closer, described first
Tapered thread linkage section 12 and the second tapered thread linkage section 42 are step-like tapered thread linkage section.Certainly, tapered thread
Linkage section can also design irregular seal groove, it is ensured that combine even closer between insulation valve cylinder.
As shown in Figure 1, in order to enable structure of the invention is more reasonable, compact, the insulation inlet suction port 1 has and ball valve
The connection endoporus 13 of assembly, the connection endoporus 13 is connected with axial connecting hole 11, and connects the axis and axial direction of endoporus 13
The axis of connecting hole 11 overlaps.
As shown in Figure 1, in insulation float 2 when by the buoyancy of water, the movement in axial connecting hole 11 of connecting rod 21 is described
