Embodiment 1

[0028] Such as figure 1 with figure 2 As shown, a multi-functional valve provided by Embodiment 1 of the present invention includes a panel 11, an air inlet 12 is opened on the panel 11, and a hose interface 13 connected to the air inlet 12 is fixed on the outside of the panel 11. The interface 13 is used to connect with an external hose (not shown). The inner side of the panel 11 is fixed with a guide pipe 14 connected to the air inlet 12 and with an upward opening. A fireproof cover 15 is set on the top of the guide pipe 14. The upper end of 15 is connected to the panel 11 through the fuse piece 16, and a recessed hole 141 is provided symmetrically on the two side walls of the guide tube 14 respectively. The rotating shaft 18 is connected with the bottom end of the fireproof cover plate 15, and the periphery of the guide tube 14 is provided with an enclosed Venturi plate 17, and the inner wall of the guide tube 14 is provided with a groove part 142, and the groove part 142...

Embodiment 2

[0039] Such as image 3 with Figure 4 As shown, the structure of the second embodiment is substantially the same as that of the first embodiment, except that the upper and lower ends of the panel 11 are longer than the upper and lower ends of the Venturi plate 17 .

Embodiment 3

[0041] Such as Figure 5 with Image 6 As shown, the structure of the third embodiment is substantially the same as that of the first embodiment, except that the upper end of the panel 11 is flush with the upper end of the Venturi plate 17 , and the lower end of the panel 11 is shorter than the lower end of the Venturi plate 17 .
