Abstract
The invention discloses a ribbon-type air flow indicator, which comprises a transparent short pipe, flanges and a ribbon assembly, wherein the flanges are arranged at two ends of the transparent short pipe for connecting the transparent short pipe in an air pipeline; the ribbon assembly is arranged inside the transparent short pipe for indicating the air flow state and the wind direction; the ribbon assembly comprises a fixing bar arranged inside the transparent short pipe and a ribbon with one end fixed on the fixing bar; and the other end of the ribbon is a free end which can float along the air flow direction. The operation is simple; the cost is low; no mechanical transmission part exits; corrosion is resisted; defects in the prior art can be overcome; the problem of insufficient air suction or air exhaust balance at the tail end of an air gathering processing or ventilation system can be effectively solved; the system debugging, operating and maintaining difficulty is greatly simplified; the number of air valves and the number of flow meters can be reduced; and the pipeline system cost is saved.
Description
Technical field
The present invention relates to collection and confinement of gases process and aeration technology field, particularly relate to a kind of 24 hours visual belt flow of air and show instrument.
Background technology
Along with the balance more and more paying attention to air quantity in the development of society and the progress of science and technology, foul gas collection process and Design of Ventilation System, the quality of air quantity balance is directly connected to the collection processing efficiency of foul gas and the homogeneity of ventilation system.
And in actual engineering, due to by all multifactor impacts as the stopping property of gas skirt, airduct size, scenery resource quality, operation condition changeable, space be installed, fit up requirement etc., often be difficult to accomplish the resistance balance between each arm during circuit design. For this reason, usually air-valve is set on each take-off pipe to regulate air quantity, by changing the drag losses of pipeline, make to realize resistance balance between each take-off pipe of system, reach design requirements. But air-valve regulates and is easier to for single or several piping systems, 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 deodorizing gathering system, heavy construction or the underground space. If it is balanced to realize each end take-off pipe air quantity, preferably each end take-off pipe is installed air-valve and is arranged gas meter, will certainly significantly increase the cost of piping system; Even if installing a large amount of air-valves and under meter, in actual motion, the resistance characteristic of each take-off pipe can change with the change of wherein a certain branch resistance characteristic, air-valve will have to repeatedly adjust, needing a large amount of personnel's observed volumes and complete EQUILIBRIUM CALCULATION FOR PROCESS, the difficulty of system debugging and later stage running maintenance is very big.
On the other hand, for the collection and confinement of gases treatment system that 24 hours run without interruption, especially night is due to the change of operation condition, has a power failure such as local or instrument damage, and the phenomenon causing system pipeline air quantity unbalance also is difficult to be found by people.
Summary of the invention
The present invention provides a kind of belt flow of air to show instrument, way is simple, with low cost, mechanical transmission parts, corrosion-resistant, it is possible to overcome the defect of prior art, effectively solve the not enough problem of balance of end air-breathing or exhaust in collection and confinement of gases process or ventilation system, the difficulty of simplified system debugging and running maintenance, reduces the quantity of air-valve and under meter greatly, saves the cost of piping system.
In order to achieve the above object, the present invention 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 inner that it is arranged on transparent short tube, is used to indicate flowing gas state and wind direction;
Described ribbon assembly comprises:
Hold-down bars, it is inner that it is arranged on 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 adopts the ribbon with color.
Described ribbon surface-coated fluorescent material.
Described transparent short tube adopts transparent material to make.
Described transparent short tube adopts 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.
The present invention has the following advantages:
Way is simple, with low cost, mechanical transmission parts, corrosion-resistant, the defect of prior art can be overcome, collection and confinement of gases process or ventilation system that flow of air shows instrument are installed, it is possible to the difficulty of simplified system debugging and running maintenance greatly, effectively solve the not enough problem of balance of end air-breathing or exhaust, reduce the quantity of air-valve and under meter, save the cost of piping system, it is possible to facilitate operational management at night personnel to the maintenance of system, ensure to run without interruption for 24 hours of system.
