Description

Gas station compressor three line aerator
Technical field
The utility model relates to a kind of gas station compressor three line aerator.
Background technique
Present taxi and private car adopt rock gas as power fuel, thus needs gas station to be that it carries out aerating.Existing gas station comprises filling machine and gas compressor, by tank car, source of the gas is transported, pass into again in filling machine after the gas of source of the gas carries out gas compression pressurization by gas compressor, filling machine is connected with pressure duct, middle pressure pipe road and low pressure line, gas compressor and pressure duct is made according to the compression ratio of gas compressor, middle pressure pipe road and low pressure line connect, can according to the storage pressure determination pressure duct treated on the automobile of aerating, middle pressure pipe road or low pressure line are communicated with the outlet pipe of filling machine, namely filling machine passes through low pressure, medium and high pressure is in turn for automobile carries out aerating.The shortcoming of this gas station is, gas compressor frequent starting, adds the frequency of utilization of gas compressor, shortens the working life of gas compressor; And when there is no source of the gas temporarily or bleed pressure is too low cause air displacement not enough time, can not aerating work be carried out, have impact on the working efficiency of whole gas station.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned defect, provides a kind of gas station compressor three line aerator that also can realize aerating operation when avoiding gas compression machine frequent starting and can ensure do not have source of the gas.
In order to solve the problems of the technologies described above, the gas station compressor three line aerator provided comprises filling machine, compressor and source of the gas steam outlet pipe, filling machine is connected with pressure duct, middle pressure pipe road and low pressure line, its structural feature is: the inlet end of described low pressure line is connected on source of the gas steam outlet pipe, source of the gas steam outlet pipe is connected to the inlet end of compressor by air inlet pipeline, the gas outlet tube road of described compressor respectively with pressure duct, middle pressure pipe road connects, described pressure duct is connected with bomb group by bypass branch, described middle pressure pipe road is connected with middle pressure bottle group by bypass branch, described air inlet pipeline is connected with after going to, is connected with breather check valve and low-pressure inlet valve, described middle pressure pipe road is equipped with the pressure inlet valve being arranged in its bypass branch front successively after going to, the high pressure check valve being positioned at its bypass branch front described pressure duct is equipped with, middle pressure pipe road and air inlet pipeline are connected with equilibrium valve between the pipeline section at breather check valve rear, described bomb group, middle pressure bottle group, breather check valve, equilibrium valve, low-pressure inlet valve, middle pressure inlet valve, high pressure check valve is all controlled by PLC, described filling machine is electrically connected with PLC.
Pressure transmitter is equipped with respectively in air inlet pipeline, pressure duct and middle pressure pipe road.
Pressure duct is connected with high pressure entry valve.
After adopting said structure, when using this device for natural gas vehicle refueling, by natural gas via source of the gas steam outlet pipe, inflated to automobiles bottle by filling machine after low pressure line, when filling machine detects that the pressure of automobiles bottle is equal with the pressure in low pressure line, low pressure line is cut off pressure pipe road and car bottle in rear connection by filling machine, now, pressure pipe road direction car bottle aerating during gas in middle pressure bottle group passes through, according to setting value, middle pressure bottle group has certain initial pressure, therefore by middle pressure bottle group in the process of car bottle aerating, compressor does not start, in the middle of the pressure of pressure bottle group decline when can not carry out aerating gradually, middle pressure pipe road cuts off and connects pressure duct by filling machine, filling machine by bomb group to car bottle aerating, therefore by process from bomb group to car bottle aerating converge in, compressor does not also start.When the gas pressure of central pressure bottle group and bomb group is not enough, compressor starts automatically, rock gas enters compressor from source of the gas steam outlet pipe through low-pressure inlet valve, filling machine is entered respectively through middle pressure inlet valve, high pressure check valve after supercharging, be that car bottle carries out aerating by filling machine, and when filling machine is no longer car bottle aerating, the compression through compressor makes rock gas enter middle pressure bottle group and bomb group; And when bleed pressure is too low or do not have source of the gas temporarily, namely in source of the gas steam outlet pipe without gas or air pressure too low time, be car bottle aerating by middle pressure bottle group and bomb group, and the gas of middle pressure bottle group can be returned compressor enter bomb group after compression through equilibrium valve, air inlet pipeline, be the aerating of car bottle high pressure again.Can be found out by above-mentioned, when using this device for car bottle aerating, no longer need frequent starting compressor, and when there is no source of the gas or bleed pressure is too low, still can be car bottle aerating.
In sum, the utility model effectively prevent high frequent and starts, and substantially prolongs the working life of compressor, and when bleed pressure is too low or without source of the gas, can is still car bottle aerating, improves the working efficiency of this aerator.
