The order filling system is characterized in that, comprising:
Compressor;
Compressor gas supplied pipeline;
Two air cylinders that above pressure rating is incomplete same;
Each air cylinder loading line, one of described each air cylinder loading line connect compressor gas supplied pipeline according to air cylinder pressure rating order from small to large, and the other end connects each air cylinder;
On each air cylinder loading line, be disposed with pressure holding valve (pressure maintaining valve), one-way valve and air cylinder steam line.
The air cylinder steam line of the air cylinder that pressure rating is the highest and the air cylinder gas ducting of this grade, compressor gas supplied pipeline cross; The air cylinder steam line of the air cylinder that described pressure rating is the highest is provided with one-way valve; Before the air cylinder steam line of the highest air cylinder of described pressure rating and compressor gas supplied pipeline intersection, also be provided with one-way valve on the compressor gas supplied pipeline after the air cylinder gas ducting of a last air cylinder and the compressor gas supplied pipeline junction.
During use, as long as set the pressure of pressure holding valve, but just the pressure rating of pressing force maintaining valve in order to the air cylinder air feed.
The utility model utilizes the order of machinery control compressor to the air cylinder air feed, and is safe and reliable, cost economy.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1.
The order filling system comprises compressor 1, and compressor 1 can directly be sold the 3a of gas system air feed to high pressure by compressor gas supplied pipeline 10.Comprise low pressure air cylinder 2c, middle pressure air cylinder 2b and high-pressure gas cylinder 2a in this order filling system.Low pressure air cylinder 2c, middle pressure air cylinder 2b and high-pressure gas cylinder 2a are connected on the compressor gas supplied pipeline 10 according to pressure order from low to high by low pressure air cylinder gas ducting 4c, middle pressure air cylinder gas ducting 4b, high-pressure gas cylinder gas ducting 4a.Be disposed with pressure holding valve 6c, one-way valve 7c and low pressure air cylinder steam line 5c on the low pressure air cylinder gas ducting 4c; The middle pressure on the air cylinder gas ducting 4b is disposed with pressure holding valve 6b, one-way valve 7b and middle pressure air cylinder steam line 5b; Be disposed with pressure holding valve 6a, one-way valve 7a and high-pressure gas cylinder steam line 5a on the high-pressure gas cylinder gas ducting 4a.Wherein, low pressure air cylinder steam line 5c connection low pressure is sold the 3c of gas system; Press during middle pressure air cylinder steam line 5b connects and sell the 3b of gas system; High-pressure gas cylinder steam line 5a connects compressor gas supplied pipeline 3a, and crosses with high-pressure gas cylinder gas ducting 4a.High-pressure gas cylinder steam line 5a is provided with one-way valve 7d, and the compressor gas supplied pipeline 10 between high-pressure gas cylinder gas ducting 4a and the middle pressure air cylinder gas ducting 4b is provided with one-way valve 7e.
