The exhaust duct is connected with the top of cabinet；Ventilation cabinet and exhaust duct docking ventilation；The slip valve plate is arranged at vent cabinet
The junction of body and exhaust duct；The sliding door is arranged on the porch of the ventilation cabinet；Merging zone method is matched somebody with somebody in the chain and rotating shaft
Move the sliding door to be turned on and off in the porch of ventilation cabinet；The rotating shaft is provided with the sprocket wheel with chain interoperation；Described turn
The gear coordinated with slip valve plate is additionally provided with axle；The gear is moved with the tooth bar on slip valve plate with drive slip valve plate is merged
It is dynamic；Slip valve plate controls exhaust duct and connects or block with ventilation cabinet.
Preferably, the rotating shaft is provided with two, and respectively first rotating shaft and the second rotating shaft；The first rotating shaft and
Two rotating shafts are both secured to the top of ventilation cabinet；The ventilation cabinet is provided with the rail groove for coordinating sliding door level to slide.
Preferably, the rotating shaft, slip valve plate are processed using cold-reduced sheet material.
The beneficial effects of the utility model are：A kind of vent cabinet for being provided with air quantity regulation push-pull valve, its simple structure are provided
Rationally, sliding door can be caused to open simultaneously with valve plate, increased the negotiability of gas, it is ensured that the multiaspect wind in vent cabinet
Speed；And structure merging precision is high, preparation cost is cheap.
