Technical field
The utility model relates to a kind of universal exhaust duct, belongs to field of mechanical technique.
Background technology
Have more harmful material in laboratory, part Experiment can produce harmful gas, needs to arrange air draft.And these experiments can not all be carried out in vent cabinet, part needs to carry out on experimental bench, and can not determine when doing experimental laboratory air exhausting system laboratory build up after specifically that position of experimental bench produce waste gas, so just can not determine the particular location of exhaust outlet.Therefore removable exhaust outlet seems particularly important.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of universal exhaust duct.
A kind of universal exhaust duct, mobile fan housing connects the first exhaust straight tube, the other end of the first exhaust straight tube connects the one or three joint lever arm cover mouth, one end of second exhaust straight tube connects the one or three joint lever arm cover mouth, the other end of the second exhaust straight tube connects the two or three joint lever arm cover mouth, one end of 3rd exhaust straight tube connects the three or three joint lever arm cover mouth, the other end of the 3rd exhaust straight tube connects the other end of the two or three joint lever arm cover mouth, the other end of the three or three joint lever arm cover mouth connects the 3rd exhaust straight tube
Hand-operated butterfly valve is provided with in second exhaust straight tube or the 3rd exhaust straight tube; Rotary joint has fixed knob;
The fixed pedestal that mobile fan housing matches with caliber, on fixed pedestal, provide air draft interface, air draft interface is connected with exhaust duct, and suction interface is connected with mobile fan housing, and air draft interface is flange-type interface.
One or three joint lever arm cover mouth, the two or three joint lever arm cover mouth and the three or three joint lever arm cover mouth: circular bowl-shape, diameter 350mm, 360 degree of rotations can regulate direction, mobile fan housing caliber is 75mm, air quantity regulates in 110 ~ 240 cubic metres/hours window, and blast is less than 300Pa; The effective radius of clean-up >=the 914mm of mobile fan housing.
The utility model has the advantages that and adopt the advantage of universal air draft pipe to be any experimental bench in universal air draft pipe coverage can be made with the experiment endangering gas discharging in a small amount, adding the flexibility of experiment, experimental facilities need not being needed to move on fixing exhaust outlet because doing certain experiment.The removable waste gas that also effectively can discharge instrument and equipment discharge of exhaust hood mouth.
