Embodiment one：Vent cabinet air-valve, as depicted in figs. 1 and 2, including air-valve body 100, is arranged on air-valve body 100
The butterfly valve piece 210 of inside, the rotating shaft 220 for being fixed on the middle part of butterfly valve piece 210.The upper and lower ends of air-valve body 100 are respectively air-out
Mouth 110 and air inlet 120, air outlet 110 is integrally formed with the air-out edge 111 for being fixed with exhaust duct, air inlet 120 1
It is body formed to have for the air intake side 121 fixed with vent cabinet top（Exhaust duct is the common external part of vent cabinet, in accompanying drawing
It is not shown）, the junction of air intake side 121 and air-out edge 111 and the outer wall of air-valve body 100 integrally formed with reinforcement 130,
The two ends of rotating shaft 220 are arranged in the side wall of air-valve body 100, and wherein side wall and driving horse of the one end through air-valve body 100
Up to 230 connections, drive motor 230 is fixed on the outer wall of air-valve body 100.
The inwall of air-valve body 100 is at air outlet 110 integrally formed with a waste collection groove 140, the waste collection
The opening of groove 140 is identical with air outlet 110 to be set upward.Reference picture 3, offers L-type groove at the inwall of air outlet 110
142, the L-type groove 142 is extended in waste collection groove 140, makes the groove width at the opening of waste collection groove 140 more than the groove of its underpart
Width, increased the capacity of waste collection groove 140；The bottom of waste collection groove 140 is set in the arc of lower recess, and its bottom
Portion is provided with a discharging tube 141, and discharging tube 141 penetrates the side wall of air-valve body 100 so as to by waste collection groove 140 and air-valve body
100 extraneous connections, for discharging waste liquid.Reference picture 4, at the mouth of pipe of discharging tube 141 opening direction from the diameter of outer wall to the mouth of pipe
It is progressively smaller until identical with the diameter of inwall at the mouth of pipe, is easy to discharging tube 141 to be connected with external pipe.
Reference picture 5, the inwall of air-valve body 100 has been wholely set a guide edge 150, the guiding at air inlet 120
The rectangular triangle in section on side 150 is set, and guide edge 150 is away from the one side of air inlet 120 and the inwall of air-valve body 100
Vertically, guide edge 150 is inclined near the one of air inlet 120 towards the direction of air outlet 110.Come from air inlet 120 during exhausting
Inclined plane of the gas along guide edge 150 near air inlet 120 is moved, by guide edge 150 by gas guide air valve body 100
Portion, reduces gas contact with the side wall of air-valve body 100 and causes the steam in gas to occur in the liquefied situation of side-walls,
Situation about being instilled so as to the waste liquid for reducing gas liquefaction generation in vent cabinet occurs.The outer wall of air-valve body 100 and guide edge 150
Integrally formed with a reinforcing edge 160, the reinforcing edge 160 is set in the arc-shaped of outwardly convex, due to being oriented to for corresponding position
