Connect, the gas outlet of compressor connects the 4th threeway, and the 4th threeway connects after the second air valve is connected with last of the second threeway
Mouth is connected, and last interface of the 4th threeway connects the 5th threeway, the 5th threeway and air accumulator after the 3rd air valve is connected
It is connected, last interface of the 5th threeway is connected after connecting the 4th air valve with last interface of the 3rd threeway, on
All connected modes are stated all to connect by pipeline.
5th air valve is set between the vaporizer and the second threeway.
The amount of capacity of the air accumulator is 2-5 times of common gas cylinder.
One air pressure monitoring device is set between the air accumulator and the 5th threeway.
Compared with prior art, the present invention increases some pipe-lines on original gas dispensing apparatus, connects one
Compressor and an air accumulator, by the ingenious setting of air valve and pipeline, realize the residual gas in pipeline being compressed to storage
Saved in gas tank, after when the gas canful preserved in air accumulator, adjust air valve, you can directly gas cylinder is filled
Dress.Present invention low cost simple in construction, simple to operate practical, not only safety and environmental protection, and saved resource reduces enterprise
Industry operation cost, adds the performance of enterprises, is worth of widely use.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
