Understand the notion of one or one group gas cylinder in many gas cylinders:
A gas cylinder notion:
A gas cylinder alternate cycles in many gas cylinders, that is: the rock gas residual air (the overbottom pressure gas that pressure reduces gradually) in gas cylinder needs the high pressure in a plurality of gas cylinders in back, in calm the anger and cooperate that just to use up (be not that any gas does not have, here refer to that pressure is less than the value of setting in the gas cylinder, as 2,3,4,5,6, a numerical value among the 7-12, unload this gas cylinder), after using up, unloading this gas cylinder goes to female station to fill it up with after the high pressure air or another is full of the gas cylinder of high pressure air, insert once more, for first gas cylinder in a plurality of gas cylinders in last round of back uses up gas, high pressure air is provided, after first gas cylinder in a plurality of gas cylinders in last round of back uses up gas, unloading this gas cylinder goes to female station to fill it up with after the high pressure air or another is full of the gas cylinder of high pressure air, also insert once more, for second gas cylinder in a plurality of gas cylinders in last last round of back (first in a plurality of gas cylinders in last round of back) uses up gas, high pressure air is provided, so so continuous circulation, constantly there is the gas cylinder that is full of high pressure air to participate in circulation, make full use of pressure reduction in the air cylinder to the aerating of automobile gas cylinder, reach the saving compressor, the function of oil hydraulic pump pressurized feed.Just a gas station just finishes automobile gas cylinder aerating task by many gas cylinders alternate cycles.No longer needing compressor, oil hydraulic pump that gas cylinder is pressurizeed finishes the aerating of automobile gas cylinder.
Illustrate: in Fig. 1, filling machine is got the rock gas in the 1st gas cylinder, pressure is more and more low, can only satisfy the more and more low low inflation requirement of automobile gas cylinder, need the middle and high cooperation in the 2nd to 8 gas cylinder, when the 1st gas cylinder to during the force value that unloads of our regulation, unload down primary gas filling station and fill it up with high pressure air and insert or directly change another bottle high pressure air again, provide high pressure air for the 2nd bottle; The 2nd gas cylinder repeats the step of the 1st gas cylinder again, for the 3rd gas cylinder provides high pressure air; Repetitive cycling circulates each time so like this, all has high pressure air to insert and participates in circulation, satisfies the aerating consumption of filling machine.
One group of gas cylinder notion:
In the practical application, many gas cylinders are divided into many groups:
One conception of species is: in Fig. 1, a plurality of air cylinders are treated as one group, serial or parallel connection becomes a big gas cylinder, be linked into by rapid pipe joint on the position of gas cylinder 1 among Fig. 1, or as gas cylinder 1, front at sensor 10 connects by rapid pipe joint, rapid pipe joint is omitted and is not drawn, in like manner, every group of a plurality of air cylinders in the gas cylinder 2 to 8 also are that serial or parallel connection becomes a gas cylinder respectively, just 1 among Fig. 1 is to 8 gas cylinders, wherein each gas cylinder all is to form one group by a plurality of air cylinder serial or parallel connections to constitute a big gas cylinder, such benefit is to strengthen the gas storage capacity of 1 to 8 gas cylinder, for example: 8 existing how long pipes (are had 6 pipes, 8 pipes, 11 pipes etc.) (vehicle-mounted total capacity is 18 cubes of water capacities to trailer, the maximum capacity of highway transport on the national regulation) a plurality of long tube gas storage steel cylinders of each in are in parallel or be connected into an air cylinder, are connected on 1 to 8 gas cylinder position in the middle of Fig. 1 by rapid pipe joint respectively.Be characterized in: take 8 trailers, still, and 88 gas cylinders that trailer constitutes, the Capacity Ratio of each gas cylinder is bigger, can arrive 18 cubes of water capacities, and the total gas storage water capacity of gas station is: 18 * 8=124 cube of water capacity.
Another kind of notion is: the air cylinder under the gas cylinder mouth more than 12 among Fig. 3 is divided into two groups, and promptly every group of 6 air cylinders are respectively: 1 to 6,7 to 12; Or being divided into three groups, i.e. every group of 4 air cylinders are respectively: 1 to 4,5 to 8,9 to 12.12 gas cylinders among Fig. 3 are not to limit number, the number for example in this case in the many gas cylinders of representative, and it also is fixed arbitrarily being divided into how many groups; For example can also be that 18 gas cylinders are divided into two groups, i.e. every group of 9 gas cylinders; Or be divided into three groups, i.e. every group of 6 gas cylinders or the like.A plurality of gas cylinders are divided into many groups, if every group of air cylinder, the grouping that is equal to nothing, every group of air cylinder should be more than two.
Many gas cylinders are meant two more than the gas cylinder, without compressor, oil hydraulic pump pressurization, finish the aerating of automobile gas cylinder by many gas cylinders alternate cycles.
The concrete number of many gas cylinders is by the capacity of gas cylinder and utilization efficiency decision, for example, pressure is at 5MPa in first gas cylinder, the 6th storage pressure is at 20MPa, at this moment, gas in these six gas cylinders have no idea the automobile gas cylinder the is filled it up with gas of 20MPa, at this moment need first gas cylinder is unloaded, unloading this gas cylinder goes to female station to fill it up with after the high pressure air or another gas cylinder that is full of high pressure air connects, could continue the aerating of automobile gas cylinder, in unloading the process of this gas cylinder, can not interrupt aerating work, need the 7th, eight gas cylinders that are full of high pressure air participate in circulation, race against time for first gas cylinder unloads with access, the 7th, the such gas cylinder of eight gas cylinders is many more, and just to unload and insert the time of striving for just many more for first gas cylinder.The concrete number of many gas cylinders generally is can circulate to add that in addition several is to unload and insert the gas cylinder that gas cylinder is raced against time.
Many gas cylinders are divided into many groups, make things convenient for the automobile transportation.
Many groups are meant two groups, more than three groups or four groups, the gas cylinder number in every group is more than two many many gas cylinders of group notions that Here it is; , it is optimum scheme that many gas cylinders are divided into the many gas cylinders of many groups, the just automobile transportation of every prescription.For example: in Fig. 3,12 gas cylinders are divided into two groups, 6 every group, promptly 1 to 6,7 to 12,6 gas cylinders are one group and are installed in and can transport 18 cubes of water capacity pressurized gass on the automobile, convenient transportation, be characterized in: take 2 trailers, each gas cylinder capacity is 3 cubes of water capacities.The total gas storage water capacity of gas station is: 18 * 2=36 cube of water capacity.Overbottom pressure gas in 1 to 6 gas cylinder needs 7 to 12 mesohigh gas supports just can use up, after overbottom pressure in 1 to 6 gas cylinder is run out of air, unload together, another is full of, and 6 gas cylinders insert 1 to 6 gas cylinder position respectively in the gas bottle truck of high-pressure natural gas, beginning is that 7 to 12 gas cylinders use up gas, and high pressure air is provided.Equally, after 7 to 12 gas cylinders used up gas, other 6 gas cylinders that are full of in the high-pressure natural gas gas bottle truck inserted 7 to 12 gas cylinder positions respectively, repetitive cycling again,
The circulation of many gas cylinders is no matter be by a gas cylinder or by one group of gas cylinder circulation, and all falling into many gas cylinders alternate cycles provides high pressure air to finish protection domain to refueling.
This case alternate cycles has three layers of implication:
The one: the pressures cycle of the rock gas in the gas cylinder, be inflated to high pressure by removing primary gas filling station, from high pressure to the low pressure alternate cycles;
The 2nd: gas cylinder is inflated to high pressure by removing primary gas filling station, and alternate cycles in many gas cylinders is for many gas cylinders whole system that circulates provides high pressure.Make and do not re-use the gas station that adopts the whole system of many gas cylinders alternate cycles compressor, oil hydraulic pump and just can finish automobile gas cylinder aerating task.
The 3rd: PLC gathers cell pressure value in the air filling gun, add a setting value, adopt sum go with many gas cylinders in pressure transducer pressure information relatively, open valve near its sum, its process is that circulation is looked for, circulated and open valve, the centre has at interval, when PLC gathers that the cell pressure value is 20MPa in the air filling gun till.

Embodiment
Technological scheme 1:
Gas circuit under many gas cylinders mouth is the single channel pipeline, and sensor, valve are installed on the single channel pipeline, and it is connected with measuring apparatus, air filling gun after corresponding sensor, the valve parallel connection separately again;
Perhaps,
Gas circuit under many gas cylinders mouth is the demultiplexing outlet pipe in parallel, sensor, valve are installed on the corresponding multiple-way duct, on the multiple-way duct separately corresponding sensor, valve between them once more after the parallel connection respectively with multiple metering device, air filling gun in a road connect;
Be connected with PLC and under its control, constitute single rifle or multiple gun filling machine;
Its technical characteristics is: PLC gathers the force value of pressure transducer in the air filling gun earlier, it is the force value in the automobile gas cylinder, add a setting value, 0＜setting value＜20, its sum goes to compare with the force value of each pressure transducer under many gas cylinders mouth, open the most approaching greater than itself and corresponding valve, use the pressure reduction aerating, before the balance or after the balance, take above-mentioned steps once more, so repeat, when the value of pressure transducer is automobile gas cylinder rated pressure value in air filling gun, rated pressure value≤20MPa, cut-off valve, aerating finishes.
In Fig. 1, describe in detail:
Gas pipeline, PLC, valve, sensor, measuring apparatus, air filling gun under many gas cylinders mouth.These six essential elementss have constituted filling machine.
1, which gas cylinder 2,3,4,5,6,7,8 represent respectively; 9 expression PLC; Pressure transducer under the 1st gas cylinder of 10 expressions; Valve under the 1st gas cylinder of 11 expressions; Pressure transducer under the same reason, the 2nd to the 8th gas cylinder and valve are as 10,11, and mark omits, and keep the drawing cleaning; Pressure transducer in the 12 expression air filling guns; 13 expression measuring apparatuss; 14 expression one-way valves; 15 expression air filling guns; 16 expression IC card reader.
1st, the capacity of 2,3,4,5,6,7,8 gas cylinders can amplify, and promptly becomes a lot of gas cylinder serial or parallel connections a big gas cylinder as one in them.1 to 8 gas cylinder in Fig. 1 be by rapid pipe joint insert respectively 1 to 8 locational.Rapid pipe joint is omitted and is not drawn.
1 to 8 gas cylinder is represented many gas cylinders, and many gas cylinders are not defined as 8 in practice, and this case illustrates the process of the alternate cycles of many gas cylinders for 8 gas cylinder examples.Many gas cylinders are exactly by many gas cylinders self alternate cycles, and promptly the overbottom pressure gas in the gas cylinder of front needs the high pressure air of the gas cylinder of back to cooperate support to use up, after using up, gas cylinder unloads, there is the gas cylinder that is full of high pressure air to insert again, begins new one again and take turns alternate cycles, have high pressure air to participate in circulation all the time.
Many gas cylinders technical characteristics is exactly: constantly have low pressure gas cylinder to unload in many gas cylinders, constantly have the gas cylinder of the high pressure air of carrying in time to insert, can realize alternate cycles.
How to realize, need this case filling machine, the job step of filling machine:
In Fig. 1
Working procedure: for example, coming the storage pressure in the taxi of gas station is 2MPa, pressure information value in the PLC9 collection air filling gun 15 on the sensor 12 is 2MPa, add a setting value 5, this setting value is our fixed in advance value, can be 1,2,3,4,5, any numerical value among the 6-19, purpose is to increase pressure reduction, 0＜setting value＜20, PLC goes to seek that the above immediate gas cylinder of pressure and 7MPa (for example has 7MPa in many gas cylinders, 8PMa, 9MPa, gas cylinders such as 10MPa), open and (open the gas cylinder of 8MPa, rather than open valve on the gas cylinder of 9MPa, 8 and 7 is the most approaching, rather than 9, if do not have 8, just select 9, rather than select 10, the most approaching is exactly this meaning,) valve on this gas cylinder, air filling gun begins the aerating of taxi gas cylinder, utilize pressure reduction to reach balance after, next remove to seek the above immediate gas cylinder of 12MPa, middle hop is crossed 9MPa, 10MPa, 11MPa, the valve of 12MPa, open this valve, inflation once more is successively from low pressure to the high pressure, get gas at interval, till when the value of pressure transducer 12 is rated pressure 20MPa in air filling gun 15, cut-off valve, aerating finishes.The Automobile air bottle pressure that rated pressure is less than or equal to the formulation of present country is 20MPa.
In order to improve aerating speed, before inflation reaches balance, when for example pressure differs 1MPa, speed is slow, and PLC gathers the information of pressure transducer in the air filling gun and opening the pressure information that adds the pressure transducer in the gas bottle and compares, when pressure differs 1MPa, close this valve in advance, add a setting value, its sum goes to compare with the force value of each pressure transducer under many gas cylinders mouth, opens the most approaching greater than itself and corresponding valve once more.So repeat.When the information of pressure transducer is 20MPa in PLC collection air filling gun, finish this taxi aerating task.Improved aerating speed like this.
At Fig. 2, the aerating principle of filling machine is the same among Fig. 3.Select Fig. 3 to illustrate the rush-harvesting and rush-planting working procedure:
In Fig. 3, outlet pipe under 1 to 12 mouthful of the gas cylinder has been in parallel the two-way outlet pipe, filling machine just is the rush-harvesting and rush-planting filling machine, wherein No. one pressure transducer 14, valve 16 under 1 to 12 gas cylinder, in parallel between them, connect with pressure transducer 21 in measuring apparatus 20, the air filling gun 22 again, under the control of PLC 13, form a road in the rush-harvesting and rush-planting filling machine, promptly control the Push And Release of 12 valves in parallel under 1 to 12 mouthful of the gas cylinder with gas cylinder 1 valve 16.
Equally, wherein another road pressure transducer 14, valve 15 under 1 to 12 gas cylinder, in parallel between them, connect with pressure transducer 18 in measuring apparatus 17, the air filling gun 18 again, under the control of PLC 13, form another road in the rush-harvesting and rush-planting filling machine, promptly control the Push And Release of 12 valves in parallel under 1 to 12 mouthful of the gas cylinder with gas cylinder 1 valve 15.
The pipeline of above-mentioned two air filling guns by separately controlled by a road in the valve of the parallel connection under many gas cylinders mouth respectively, and both do not disturb mutually, respectively add the gas of each, and the concrete aerating flow process of single air filling gun 22,18 sees the narration of air filling gun 15 among Fig. 1 for details.
Specify:
By the gas path pipe under many gas cylinders mouth, sensor, valve, measuring apparatus, air filling gun and PLC totally six various connection diagrams that element constitutes, just, the installation form of six essential elementss of this case between them can be various variation, anyone has seen this case connection diagram, can also association go out other connection diagram, for example: the connecting means of Fig. 4.
In Fig. 4, by the gas path pipe under many gas cylinders mouth, sensor, valve, measuring apparatus, air filling gun and PLC totally six elements constitute, many gas cylinders among Fig. 1 are made a control unit, and several such control units parallel connections and measuring apparatus, air filling gun series connection constitute a filling machine.Wherein the information of the pressure transducer 12 in the air filling gun 15 is compared with the pressure transducer under many gas cylinders mouth by the signaling line or the wireless communication module of the PORT COM between the PLC9, and the PLC of unit controls the Push And Release of the valve of the correspondence under many gas cylinders mouth of unit separately separately.Several such unit provide high pressure air as the same many gas cylinders alternate cycles that realizes of the many groups of many gas cylinders,
Fig. 4 equally also can realize the function of the filling machine of this case.
We have no idea to list one by one all connection diagrams and are protected; the present invention is made of the gas path pipe upper sensor, valve, measuring apparatus, air filling gun and the PLC that are installed under many gas cylinders mouth; as long as its effect reaches: the technical characteristics of this case all is considered as falling into the protection domain of this case filling machine.
Technological scheme 2:
Gas station is made up of many gas cylinders and filling machine, and its technical characteristics is: many gas cylinders alternate cycles provides high pressure air, satisfies single rifle of filling machine or multiple gun to the continuous aerating consumption of automobile gas cylinder.
Many gas cylinders alternate cycles provides the high pressure air technical characteristics:
In many gas cylinders one or one group of gas cylinder need a plurality of of its back or, organize gas cylinder more provides high pressure air to be used, when its pressure less than the needs of our regulation when unloading the setting value of gas cylinder, 0＜setting value＜12MPa, unload down that primary gas filling station fills it up with that high pressure air inserts once more or directly insert or the one group of gas cylinder that is full of high pressure air in addition, for first or first group of gas cylinder of last round of back provides high pressure air;
First of last round of back or first group of gas cylinder repeat above-mentioned steps;
So repeat, have the gas cylinder of the high pressure air filled to insert the participation circulation all the time;
Realize that many gas cylinders alternate cycles provides high pressure air for the filling machine that adopts many gas cylinders circulating system, filling machine impel many gas cylinders can alternate cycles again to additional gas continuously.
In Fig. 1:
We suppose 1 to 8 gas cylinder, and the water capacity of each bottle is 3 cubes, and the rock gas that is full of 25MPa reaches 1200 cubes, and the taxi gas cylinder is 15L, and the gas cylinder rated working pressure is limited in the 20MPa.
Qualitative analysis, simulation develops, and many gas cylinders alternate cycles process is described.
When taxi comes gas station when inflation, the PLC9 in the filling machine information in the pressure transducer 12 in the air filling gun 15 of gathering generally is that pressure in the pressure transducer 12 in the air filling gun 15 adds that a setting value removes to seek minimum again, successively from low pressure to the high pressure.For example: the taxi storage pressure of pressure transducer detection arrival gas station is 3MPa in the air filling gun, adds that a setting value 3 equals 6, goes for greater than the most close gas cylinder of 6MPa pressure and opens its valve, the beginning aerating.Setting value is littler, and aerating speed is slower, and the number of times of opening valve the more.Certainly, in order to improve aerating speed, before their balances, when air pressure differed 1MPa, cut-off valve repeated above-mentioned steps in advance, improves aerating speed.
The 1st to the 20th aerating:
The 25MPa pressure of the 1st gas cylinder begins to drop to 23MPa;
The 21st to the 40th aerating:
The 23MPa pressure of the 1st gas cylinder begins to drop to 18MPa; The pressure 25MPa pressure of the 2nd gas cylinder begins to descend;
The 41st to the 60th aerating:
The 18MPa pressure of the 1st gas cylinder begins to drop to 10MPa; The pressure of the 2nd gas cylinder drops to 18MPa pressure; The pressure 25MPa pressure of the 3rd gas cylinder begins to descend;
The 61st to the 80th aerating:
The 10MPa pressure of the 1st gas cylinder begins to drop to 8MPa; The pressure of the 2nd gas cylinder drops to 15MPa pressure; The pressure of the 3rd gas cylinder is reduced to 20MPa pressure and is begun to descend; The pressure 25MPa pressure of the 4th gas cylinder begins to descend;
The 81st to the 100th aerating:
The 8MPa pressure of the 1st gas cylinder begins to drop to 3MPa; The pressure of the 2nd gas cylinder drops to 10MPa pressure; The pressure of the 3rd gas cylinder drops to 15MPa; The pressure 18MPa pressure of the 4th gas cylinder begins to descend; The pressure of the 5th gas cylinder drops to 22MPa; The pressure 25MPa pressure of the 6th gas cylinder begins to descend;
At this moment we unload the 1st gas cylinder, connect a gas cylinder that is full of high pressure air and insert as the 8th gas cylinder, and the 2nd to 8 gas cylinder originally is the 1st to 7 gas cylinder, are again that 1 to 8 gas cylinder is in circulation again now.
Said process is got gas by filling machine and is realized that working procedure is as follows from low pressure to the high-tension cell:
The information that PLC 9 collects the pressure transducer 12 in the air filling gun 15, compare with the pressure transducer 10 under 1 to 8 gas cylinder, in the time of relatively, adding a setting value 3, also can be data such as 4,5,6, increase pressure reduction, open valve under 1 to 8 gas cylinder at interval according to force value from low pressure to the high pressure, 8 valves under 1 to 8 gas cylinder are in parallel, once can only have one to open valve, connect with measuring apparatus, air filling gun, all rock gases all pass through measuring apparatus, air filling gun is finished the aerating of automobile gas cylinder.
We find out that the outlet pipe under 1 to 8 gas cylinder is the single channel pipeline, can only connect a measuring apparatus, an air filling gun is worked.
In Fig. 3:
Outlet pipe under many gas cylinders mouth also is unified into two outlet pipes, and this example is the rush-harvesting and rush-planting gas station that rush-harvesting and rush-planting filling machine and many gas cylinders constitute, and can connect two measuring apparatuss, two air filling guns.
1, which gas cylinder 2,3,4,5,6,7,8,9,10,11,12 represent respectively; 13 expression PLC; Pressure transducer under the 1st gas cylinder of 14 expressions; Valve under the 1st gas cylinder mouth of 15 expressions on one road outlet pipe of parallel connection; Valve under the 1st gas cylinder mouth of 16 expressions on another road outlet pipe of parallel connection; Pressure transducer under the same reason, the 2nd to the 12nd gas cylinder and valve are as 14,15,16, and mark omits, and keep the drawing cleaning; 17 expression measuring apparatuss; Pressure transducer in the 18 expression air filling guns; 19 expression air filling guns; 20 expression measuring apparatuss; Pressure transducer in the 21 expression air filling guns; 22 expression air filling guns.
We are divided into two groups to 1 to 12 gas cylinder, all are to be connected with the position of 1 to 12 gas cylinder among Fig. 3 by rapid pipe joint.Promptly 1 to 6 one group, 7 to 12 1 groups, purpose is to allow these two groups of alternate cycles, in the protection domain of many gas cylinders alternate cycles.Unloading next gas cylinder for unloading next group gas cylinder, this group gas cylinder is contained on the automobile, convenient transportation.
We see the working procedure of two air filling guns earlier:
Two air filling guns can be worked simultaneously, and aerating efficient improves, and we see how alternate cycles of many gas cylinders again.
1 to 12 gas cylinder, the water capacity of each bottle is 3 cubes, is full of the rock gas of 25MPa, and the taxi gas cylinder is 15L, and working pressure is limited in the 20MPa.
When taxi comes the gas station inflation, use 19 air filling guns, PLC13 in the filling machine gathers information in the pressure transducer 18 in the air filling gun 19, generally be in the pressure transducer 18 in the air filling gun 19 pressure add a setting value go again to seek near itself and value, successively from low pressure to the high pressure.For example: the taxi storage pressure of pressure transducer detection arrival gas station is 3MPa in the air filling gun, adds that a setting value 3 equals 6, goes for the close gas cylinder of 6MPa pressure and opens its valve, the beginning aerating.After utilizing pressure reduction to reach balance, repeat above-mentioned steps, go to repeat to seek to high pressure from low pressure at interval, till the force value of the pressure transducer in air filling gun is 20MPa, cut-off valve, aerating finishes.
Data are simulation, and qualitative analysis illustrates that many gas cylinders organize the alternate cycles process more.
