Please refer to Fig. 2, this figure is the working principle schematic representation of first kind of air entraining substation pipe-line system providing of the utility model, simultaneously, also is first kind of air entraining substation controlling method flow chart that the utility model provides.The air entraining substation controlling method comprises two-part: the one, and to the operation of fortune gas cylinder group, the 2nd, to the operation of air cylinder group in standing.These two-part are to carry out respectively, except that offering some clarification on, do not influence each other between the two.
Operation to fortune gas cylinder group 200 comprises step:
S110, according to predetermined at least one fortune gas cylinder 201 of policy selection as the low pressure air feed bottle.Predetermined strategy comprises multiple mode, can select according to the pressure in each fortune gas cylinder 201; Also can select according to the amount of CNG in each fortune gas cylinder 201; Can also select one or more fortune gas cylinders 201 as the low pressure air feed bottle successively according to predetermined order more in advance with each fortune gas cylinder 201 numbering; Can also be according to treating that the selection of aerating automobile gas holder internal pressure has the fortune gas cylinder 201 of suitable pressure, to obtain a suitable aerating pressure difference, the flow velocity of CNG during the control aerating; The low pressure port of filling machine 400 is associated with high-pressure mouth, and selecting the fortune gas cylinder 201 of fortune gas cylinder 201 internal pressures in prespecified range according to high-pressure mouth pressure is the low pressure air feed bottle, or the like.
S120 opens the outlet valve of low pressure air feed bottle.After opening the low pressure air feed bottle, its inner CNG can outwards flow by first pipeline 204, can arrive the low pressure port L of filling machine 400 further by second pipeline 306, outwards supplies with CNG with the low pressure port L by filling machine 400.
S130, when the CNG amount in the low pressure air feed bottle was less than predetermined value, selecting at least one other fortune gas cylinder 201 according to predetermined policy was the low pressure air feed bottle, returns step S120.
Carry out said process repeatedly, can make the outside CNG of supply of each fortune gas cylinder 201 orders in the whole fortune gas cylinder group 200, make air entraining substation have low pressure air feed source of the gas continuously.
For the CNG in each fortune gas cylinder 201 is flowed out as much as possible, improve gas taking rate to fortune gas cylinder group 200, can also utilize booster body 100 for the supercharging of low pressure air feed bottle, release as much as possible with the CNG that it is inner.Therefore, between step S120 and step S130, described operation to fortune gas cylinder group also is included as the step S111 of low pressure air feed bottle supercharging.
S111 when low pressure air feed bottle internal pressure is lower than predetermined value, makes low pressure air feed bottle pressurized end be connected with the boost port of booster body 100.In the low pressure air feed bottle, inject the supercharging medium by booster body 100, be low pressure air feed gas storage supercharging.
In this example, because booster body 100 has a boost port, this booster body 100 not only will be given 200 superchargings of fortune gas cylinder group, also to give air cylinder group 300 superchargings in the station, and because fortune gas cylinder 201 is different with the nominal operating pressure of air cylinder 301 in the station, therefore, booster body air cylinder group 300 superchargings in fortune gas cylinder group 200 and station simultaneously within the predetermined time.Therefore, preferred, in step S111, before making low pressure air feed bottle pressurized end and the boost port of booster body 100 be connected, to determine that also can booster body 100 give the supercharging of low pressure air feed bottle, when booster body 100 is given in the station 300 superchargings of air cylinder group, just can not give the supercharging of low pressure air feed bottle.Therefore, step S111 can also for: when booster body 100 can be lower than predetermined value for the supercharging of low pressure air feed bottle and low pressure air feed bottle internal pressure, low pressure air feed bottle pressurized end is connected with the boost port of booster body 100.This example is to operate with air cylinder group 300 preferential superchargings in standing.At booster body 100 boost port is arranged, those skilled in the art can determine that also promptly the time according to demand is that the basis determines that booster body 100 is to be air cylinder group 300 superchargings in standing, and still is 200 superchargings of fortune gas cylinder group according to the time priority principle.Booster body 100 can be provided with different relief valves or safety valve, for air cylinder group 300 in standing or 200 superchargings of fortune gas cylinder group the time, different relief valves or safety valve are connected with boost port, to obtain different system pressures, satisfy needs for air cylinder group 300 and 200 superchargings of fortune gas cylinder group in the station.
Certainly, when air entraining substation system comprises two boost port, can pass through known manner,, and make two boost port be respectively air cylinder group 300 superchargings in fortune gas cylinder group 200 and the station for each boost port is set different pressure.Such as: when booster body has two high-pressure service pumps, can make different high-pressure service pumps be respectively air cylinder group 300 and 200 superchargings of fortune gas cylinder group in the station; When having a high-pressure service pump, in for the station when air cylinder group 300 and 200 superchargings of fortune gas cylinder group, different relief valves or safety valve are connected, with different boost port to obtain different system pressures.
In the optimized technical scheme, between step S120 and step S130, described operation to fortune gas cylinder group 200 also comprises step S112:
S112, the pressure in the low pressure air feed bottle is higher than predetermined value, when perhaps the time that predetermined pressure keeps in the low pressure air feed bottle surpasses predetermined length, then the outlet valve 202 of other at least one fortune gas cylinder 201 in the fortune gas cylinder group 200 is opened.
The meaning that increases this step is: the pressure ratio in the low pressure air feed bottle is higher, or keep-ups pressure higher state during the long period, utilizes this pressure, and the low pressure air feed bottle is inflated in other fortune gas cylinders.Can when the aerating ebb, make fortune gas cylinder group 200 store more aerating energy like this, interim to come on the aerating peak, for more vehicle air feed, satisfy peak aerating needs.Opening the mode of other fortune gas cylinders can select according to actual conditions, such as: can also can select according to select progressively in advance, can also select according to the pressure in other fortune gas cylinders according to the CNG amount of other fortune gas cylinders, or the like; Preferably, when fortune gas cylinder A1 is low pressure air feed gas cylinder, open fortune gas cylinder A2-Am at interval, add inflation in each fortune gas cylinder 201 with order by predetermined order and preset time.
Should be noted that: above-mentioned low pressure air feed bottle air feed, not only comprise air feed to filling machine 400 low pressure ports, also comprise to following as the station of high-pressure air feed bottle in air cylinder 301 air feed.
Operation to air cylinder group in standing may further comprise the steps:
S210, air cylinder was as the high-pressure air feed bottle at least one was stood according to predetermined policy selection.The low pressure air feed bottle is identical with selecting, and predetermined strategy can have multiple choices, does not repeat them here.In this example, selecting the interior air cylinder B1 in station is the high-pressure air feed bottle.
S220 opens the outlet valve 303 of high-pressure air feed bottle.Make the inner CNG of high-pressure air feed bottle can arrive the high-pressure mouth H of filling machine 400, so that the high-pressure mouth H of filling machine 400 outwards supplies with CNG.
S230, when described high-pressure air feed bottle can not satisfy the high-pressure air feed needs, selecting the other interior air cylinder at least one station according to predetermined policy was interim high-pressure air feed bottle, and opens the outlet valve 303 of interim high-pressure air feed bottle; Close the outlet valve 303 of high-pressure air feed bottle, open the suction valve of high-pressure air feed bottle, the CNG that fortune gas cylinder group is discharged mends into the high-pressure air feed bottle, treat that tonifying Qi is finished after, enter next step.
Judge whether the high-pressure air feed bottle satisfies the high-pressure air feed needs multiple mode can be arranged, and can measure the CNG flow velocity of high-pressure air feed bottle output terminal, can measure the pressure in the high-pressure air feed bottle, can also determine the amount of CNG in the high-pressure air feed bottle by known mode.
Selecting the other interior air cylinder 301 at least one station according to predetermined policy is in the interim high-pressure air feed bottle, predetermined policy can be identical with the predetermined policy among the above-mentioned steps S130, air cylinder satisfies the high-pressure air feed needs as interim high-pressure air feed bottle in the suitable station to select.In this example, selecting the interior air cylinder B2 in station is interim high-pressure air feed bottle.
In this step, open the suction valve of high-pressure air feed bottle B1, the CNG that fortune gas cylinder group 200 is discharged mends into the concrete grammar of high-pressure air feed bottle B1 can be the reflux valve of opening high-pressure air feed bottle B1 earlier, after treating that the supercharging medium back flow finishes in the high-pressure air feed bottle B1, again the closing volume valve, open suction valve 302; Because the output terminal of air cylinder 301 all is connected with second pipeline 306 by suction valve 302 in each station, when opening the suction valve 302 of high-pressure air feed bottle B1, the CNG that discharges from the low pressure air feed bottle can inject high-pressure air feed bottle B1 by suction valve 302; When CNG pressure reached balance in the pressure in high-pressure air feed bottle B1 and second pipeline 306, tonifying Qi was finished, and enters next step again.It will be understood by those skilled in the art that also and can simultaneously suction valve 302 and reflux valve be opened.Tonifying Qi is finished and is not limited to reach balance with CNG pressure in the pressure among the high-pressure air feed bottle B1 and second pipeline 306 and is as the criterion, and also can reach predetermined value at high-pressure air feed bottle B1 pressure, or high-pressure air feed bottle B1 output terminal CNG flow is lower than predetermined value and is as the criterion.When the air entraining substation pipe-line system has other concrete structures, also can mend among the high-pressure air feed bottle B1 by the CNG that other concrete modes are discharged the low pressure air feed bottle.
S240 makes high-pressure air feed bottle B1 pressurized end be connected with the boost port of booster body 100, makes high-pressure air feed bottle B1 satisfy the high-pressure air feed needs, returns step S220.After tonifying Qi is finished,, therefore, high-pressure air feed bottle B1 internal pressure is increased, to satisfy the needs of high-pressure air feed because the CNG pressure that the low pressure air feed bottle is supplied with is lower than the high-pressure air feed needs.Therefore, needing by booster body 100 is high-pressure air feed bottle B1 supercharging, when treating that high-pressure air feed bottle B1 internal pressure reaches predetermined value, makes high-pressure air feed bottle B1 supply with high pressure air to the high-pressure mouth H of filling machine 400 again.In the optimized technical scheme,, close the outlet valve 303 of interim high-pressure air feed bottle B2, make interim high-pressure air feed bottle B2 stop air feed returning step S220 simultaneously.
With above-mentioned similar to the step S112 in 200 operations of fortune gas cylinder group, between step S220 and step S230, described operation to air cylinder group 300 in standing can also comprise step S221:
S221, the pressure in the high-pressure air feed bottle is higher than predetermined value, and when perhaps the time of the interior predetermined pressure maintenance of high-pressure air feed bottle surpassed predetermined length, the outlet valve 303 of other at least one interior gas storage gas cylinder 301 in station was opened in the interior air cylinder group of then will standing.The mode of opening air cylinder 301 in other stations can have multiple choices, and is similar with the explanation of above-mentioned steps S112, repeats no more.Equally, preferred, when air cylinder B1 is the high-pressure air feed gas cylinder in the station, open fortune gas cylinder B2-Bn at interval, with the inflation in the air cylinder 301 in the station of predetermined order by predetermined order and preset time.
According to foregoing description and explanation, can determine in the air entraining substation pipe-line system that the utility model provides, make the nominal operating pressure of fortune gas cylinder group reach 20MPa, the nominal operating pressure of air cylinder in the station is reached at 25MPa, can guarantee the Security of air entraining substation meeting the nation's security regulation; Simultaneously, because air cylinder 301 is connected by the output terminal of suction valve 302 with fortune gas cylinder group 200 each fortune gas cylinder 201 in the station, when air cylinder 301 emptyings or CNG amount is less than predetermined value in the station, air cylinder 301 at least one stations in the CNG injection that fortune gas cylinder group 200 is discharged is arrived at a station in the air cylinder group 300 passes through the pressure that booster body 100 increases air cylinder 301 in the station again; This just makes the air entraining substation pipe-line system not only can use fortune gas cylinder 201 to the low pressure port L of filling machine 400 air feed, CNG in the fortune gas cylinder 201 can also be injected the interior air cylinder 301 that arrives at a station, pass through boost pressure again, CNG in the fortune gas cylinder group is passed through high-pressure mouth H with the outside air feed of higher pressure, increasing system pressure reduction, the gas supply capacity of raising air entraining substation.
According to above description, as can be seen, key of the present utility model is to make the CNG of fortune gas cylinder group 200 mend inbound interior air cylinder group 300; On the one hand, the CNG amount in can guaranteeing like this to stand in the air cylinder 301 guarantees the supply of high-pressure air feed source of the gas; On the other hand, can utilize the interior air cylinder group 300 in station to have the advantage of higher working pressure like this, improve the pressure difference of system, and then improve the aerating speed of high pressure air filling gun.
The reason that the high-pressure air feed bottle can not satisfy the high-pressure air feed needs is that mainly its internal pressure is lower than predetermined value, have two reasons and the high-pressure air feed bottle pressure is low: the CNG amount is less than predetermined value in the high-pressure air feed bottle, the 2nd, also have a certain amount of CNG in the high-pressure air feed bottle, but its space is bigger, makes that its internal pressure is lower.When in the high-pressure air feed bottle, a certain amount of CNG being arranged, also can improve its pressure, satisfy the high-pressure air feed needs by the mode of direct supercharging.In order to distinguish above-mentioned different situations, also provide the controlling method of second kind of air entraining substation at the utility model.
