Description
Technical field
This utility model relates to collection and confinement of gases and processes and aeration technology field, particularly relates to a kind of 24 hours visual belt flow of air and shows instrument.
Background technology
Along with development and the progress of science and technology of society, increasingly paying attention to the balance of air quantity in foul gas collection process and Design of Ventilation System, the quality of air balance is directly connected to collection treatment effeciency and the uniformity of ventilating system of foul gas.
And in Practical Project, owing to being affected sealing such as gas skirt, airduct size, scenery resource quality, changeable, the installing space of operating condition, finishing requirement etc. by factors, during circuit design, often it is difficult to the resistance balance between each arm.To this end, generally to arrange air-valve on each branched pipe to regulate air quantity, by changing the drag losses of pipeline, make to realize resistance balance between each branched pipe of system, reach to design requirement.But air-valve regulation is easier to for single or number bye-pass system, but complicated for pipeline, air-breathing or the various system of Exhaust branch pipeline, the such as air supplying and exhausting system of large-scale wastewater treatment plant deodorization collection system, heavy construction or the underground space.If realizing the manage-style amount equilibrium of each end branch, best each end branch pipe is installed air-valve and arranges gas flowmeter, and the cost of pipe-line system will certainly be significantly increased；Even if installing substantial amounts of air-valve and effusion meter, in actual motion, the drag characteristic of each branched pipe can change with the change of the most a certain branch resistance characteristic, air-valve will have to repeatedly adjust, needing substantial amounts of personnel's observed volume and complete EQUILIBRIUM CALCULATION FOR PROCESS, the difficulty of system debug and later stage operation maintenance is the biggest.
On the other hand, for the collection and confinement of gases processing system of uninterrupted operation in 24 hours, especially night due to the change of operating condition, such as brown-outs or instrument is damaged, and the phenomenon causing system pipeline air quantity unbalance also is difficult to be found by people.
Utility model content
This utility model provides a kind of belt flow of air to show instrument, way is simple, with low cost, mechanical drive disk assembly, corrosion-resistant, it is possible to overcome the defect of prior art, effectively solve collection and confinement of gases to process or end air-breathing or the balance deficiency problem of aerofluxus in ventilating system, it is greatly simplified the difficulty of system debug and operation maintenance, reduces air-valve and the quantity of effusion meter, save the cost of pipe-line system.
In order to achieve the above object, this utility model provides a kind of belt flow of air to show instrument, comprises:
Transparent short tube；
Flange, it is arranged on the two ends of transparent short tube, for being connected in airduct pipeline by transparent short tube；
Ribbon assembly, it is arranged on inside transparent short tube, is used for indicating flowing gas state and wind direction；
Described ribbon assembly comprises:
Hold-down bars, it is arranged on inside transparent short tube；
Ribbon, its one end is fixed on hold-down bars, and the other end is free end, can wave along gas flow direction.
Described ribbon uses has coloured ribbon.
Described ribbon surface-coated fluorescent material.
Described transparent short tube uses transparent material to make.
Described transparent short tube uses corrosion resistant transparent material to make.
Arranging projecting apertures on described transparent short tube, this projecting apertures is arranged on around the junction of hold-down bars and transparent short tube.
This utility model has the advantage that
Way is simple, with low cost, mechanical drive disk assembly, corrosion-resistant, the defect of prior art can be overcome, flow of air is installed and shows that the collection and confinement of gases of instrument processes or ventilating system, it is possible to be greatly simplified the difficulty of system debug and operation maintenance, effectively solve end air-breathing or the balance deficiency problem of aerofluxus, reduce air-valve and the quantity of effusion meter, save the cost of pipe-line system, it is possible to facilitate operational management at the night personnel maintenance to system, it is ensured that uninterrupted operations in 24 hours of system.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of belt flow of air that this utility model provides shows instrument.
Detailed description of the invention
Preferred embodiment of the present utility model is illustrated below according to Fig. 1.
As it is shown in figure 1, this utility model provides a kind of belt flow of air to show instrument, comprise:
Transparent short tube 1；
Flange 2, it is arranged on the two ends of transparent short tube 1, for being connected in airduct pipeline by transparent short tube 1；
Ribbon assembly, it is internal that it is arranged on transparent short tube 1, is used for indicating flowing gas state and wind direction.
Described transparent short tube 1 uses transparent material to make, such as: lucite；When the belt flow of air that this utility model provides shows instrument for foul smell collection processing system implementing, described transparent short tube 1 uses corrosion resistant transparent material to make.
Described ribbon assembly comprises:
Hold-down bars 301, it is internal that it is arranged on transparent short tube 1；
Ribbon 302, its one end is fixed on hold-down bars 301, and the other end is free end, can wave along gas flow direction.
When the belt flow of air that this utility model provides shows instrument inside by gas, waving in the direction that ribbon 302 flows to gas, completes instruction function.
Described ribbon 302 uses has coloured ribbon, it is simple to observe, and ribbon 302 surface-coated fluorescent material, facilitates operational management personnel's night inspection.
Can arrange projecting apertures 4 on described transparent short tube 1, this projecting apertures 4 is arranged on around the junction of hold-down bars 301 and transparent short tube 1, is used for keeping in repair dismounting ribbon assembly.
