Abstract
The invention relates to a device capable of directly observing the gas flow rate. The device comprises an air inlet pipe (1), a device wall (2) and an air outlet part (3), wherein a cavity (4) is formed by the air inlet pipe (1) and the device wall (2); the cavity (4) is filled with liquid (5); the tail part (11) of the air inlet pipe is dipped by the liquid (5); and the air outlet part (3) is arranged on the upper part of the device wall (2). Compared with the prior art, the device has the advantages of simple and practical structure, low manufacture cost and convenience in use.
Description
Technical field
The present invention relates to a kind of device of observing the air-flow speed, especially relate to a kind of device that can directly observe out the gas flow rate speed.
Background technology
In industrial activity or the research work, have a lot of places need observe out the speed of gas flow rate intuitively, the result who draws by observation, and then adjustments of gas operation valve reach suitable air inlet speed.
The accurately gas meter of measurement gas airflow rate speed is arranged much at present, and these flowmeter structures are more complicated all, and the manufacturing cost height uses inconvenient.Under the occasion of some needs observation gas velocity speeds, it or not special practicality.
Summary of the invention
Purpose of the present invention is exactly the device that a kind of simple in structure, easy to use, low cost of manufacture is provided in order to overcome the defective that above-mentioned prior art exists, can observes the body air-flow speed of giving vent to anger.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of device that can observe out the gas flow rate speed intuitively, comprise draft tube, wall, outlet gas part, draft tube and wall form cavity, carrying liquid in the cavity, the height of liquid is higher than the afterbody of draft tube, gas flows in the liquid in the cavity by draft tube and forms bubble, directly observes the flow velocity speed of air-flow by the formation speed of bubble, and then according to the suitable airflow rate of speed conciliation of air-flow.
If the present invention connects chemical reaction equipment, then because the variation of reaction unit internal pressure may cause device generation suck-back phenomenon of the present invention.In order to prevent the generation of this phenomenon, can become big to draft tube middle part volume, comprise at least one ball or oval ball, the volume of ball or oval ball is greater than liquid volume; When producing the suck-back phenomenon, liquid can slowly rise along the draft tube afterbody, arrives the draft tube middle part; When liquid all was inhaled into ball or oval ball, the liquid middle part can produce the air-flow slit, thereby can play the generation that prevents the suck-back phenomenon.
For the flow velocity speed of more accurate observation draft, the draft tube afterbody can be circular hole, and Circularhole diameter is 0.5-10mm.
Described outlet gas part is tubulose or circular hole.
When weather is colder, select the lower liquid of some solidifying points in the cavity, as polyvalent alcohol.When the weather comparative heat, select some solidifying points than higher in the cavity, the liquid that viscosity ratio is less is as water.
Observe the generation speed of bubble for convenience, described draft tube, wall, the material of outlet gas part is transparent material, preferred glass.
Compared with prior art, the present invention is simple in structure, practical, low cost of manufacture, and is easy to use.
