Description

本発明は、自動車の燃料として実用化されつつある水素ガス、天然ガス等の高圧ガス用のガス充填装置に関する。   The present invention relates to a gas filling device for high-pressure gas such as hydrogen gas and natural gas that is being put into practical use as a fuel for automobiles.

石油の枯渇及び公害問題から、自動車の燃料として水素ガス、天然ガス等が実用化されつつある。これらのガスを入れる燃料タンクは、自動車に搭載する関係から小さい方が良く、自動車の走行距離を伸ばすために高圧となる。そして、燃料タンクへガスを充填するには、ガス充填装置側の圧力と燃料タンク側の圧力差でおこなうために、流路抵抗が大きいと流量が制限され、充填時間が長く掛かる不都合がある。   Due to oil depletion and pollution problems, hydrogen gas, natural gas, and the like are being put to practical use as fuel for automobiles. The fuel tank for storing these gases should be small because it is mounted on an automobile, and has a high pressure in order to extend the travel distance of the automobile. In order to fill the fuel tank with the gas, the difference between the pressure on the gas filling device side and the pressure on the fuel tank side is performed. Therefore, if the flow path resistance is large, the flow rate is limited and the filling time is long.

このような条件のガスを計量する流量計は、口径が３ｍｍ程度の小口径ものは計量精度が良く、生産量が多く比較的に安価である。しかし、口径が７ｍｍ程度の大口径ものは大流量では計量精度が良いが、小流量では計量精度が悪い。また、大口径のものは生産量が少なく高価である。一方、流量制御弁及び遮断弁は構造が簡単であるので、口径が７ｍｍ程度のものでも制御精度がよく、生産量が多く比較的に安価である。   A flow meter that measures gas under such conditions has a small diameter of about 3 mm and has good measurement accuracy, a large production volume, and a relatively low price. However, a large diameter of about 7 mm has good measurement accuracy at a large flow rate, but poor measurement accuracy at a small flow rate. Large diameter ones are less expensive and expensive. On the other hand, since the flow control valve and the shutoff valve have a simple structure, even when the diameter is about 7 mm, the control accuracy is good, the production amount is large, and the cost is relatively low.

乗用車及び小型トラック等、小流量で充填するに適するように、口径３ｍｍの流量計を使用すると、計量精度が良く安価なガス充填装置となるが、バス及び大型トラック等に充填する場合は、流量計の流路抵抗が大きく、充填時間が長く掛かる不都合がある。特に充填量が多いバス及び大型トラックでは、充填時間が３０分以上も掛かり、経済的に成り立たないことになる。他方、バス及び大型トラック等、大流量で充填するに適するように、口径７ｍｍの流量計を使用すると、充填時間が短くなるが、高価なガス充填装置となる。そして、乗用車及び小型トラック等に充填する場合は、流量を絞って充填することになり、計量精度が悪くなる不都合がある。   If a 3mm diameter flow meter is used so that it is suitable for filling with small flow rates such as passenger cars and small trucks, it will be a gas filling device with good measurement accuracy and low cost, but when filling buses and large trucks, etc. There is a disadvantage that the flow path resistance of the meter is large and the filling time is long. Particularly in buses and large trucks with a large filling amount, the filling time takes 30 minutes or more, which is not economical. On the other hand, if a flowmeter with a diameter of 7 mm is used so as to be suitable for filling with a large flow rate such as a bus and a large truck, the filling time is shortened, but an expensive gas filling device is obtained. And when filling in a passenger car, a small truck, etc., it will fill up by restrict | squeezing flow volume, and there exists a problem that measurement accuracy worsens.

本出願人は、高圧ガス用のガス充填装置を提案している。この提案は有効であるが、上述した不都合、即ち、大流量でも小流量でも計量精度良く充填できる安価なガス充填装置とはなっていない。   The present applicant has proposed a gas filling device for high-pressure gas. Although this proposal is effective, it is not an inexpensive gas filling device that can be charged with high accuracy even at a large flow rate or a small flow rate.

図１、２に基づいて本発明のガス充填装置の実施の形態を説明する。図１は、ガス充填装置の全体を示す模式図、図２は、ガス充填装置で自動車へガスを充填する制御フロー図である。   An embodiment of the gas filling apparatus of the present invention will be described based on FIGS. FIG. 1 is a schematic diagram showing the entire gas filling device, and FIG. 2 is a control flow diagram for filling a vehicle with gas by the gas filling device.

ガス充填装置１のハウジング２には、充填機構３と制御機構４が組み込まれている。   A filling mechanism 3 and a control mechanism 4 are incorporated in the housing 2 of the gas filling apparatus 1.

充填機構３のガス供給源に接続された流入管５に流量制御弁２６を介装し、該流量制御弁２６の吐出側の管を２本に分岐し、一方の分岐管６には遮断弁８、流量計９が介装され、他方の分岐管１０にも遮断弁１２、流量計１３が介装されている。   The inflow pipe 5 connected to the gas supply source of the filling mechanism 3 is provided with a flow control valve 26, the discharge side pipe of the flow control valve 26 is branched into two, and one branch pipe 6 has a shutoff valve. 8, a flow meter 9 is interposed, and the other branch pipe 10 is also provided with a shutoff valve 12 and a flow meter 13.

両分岐管６、１０は一本の流出管１４に接続され、該流出管１４には充填ホース１５が接続され、充填ホース１５の先端に充填ノズル１６が設けられ、ハウジング２には充填ノズル１６を掛けるノズル掛け１７が設けられている。そして、流入管５はガスタンク等のガス供給源１８からの供給管１９に接続されている。   Both branch pipes 6, 10 are connected to one outflow pipe 14, a filling hose 15 is connected to the outflow pipe 14, a filling nozzle 16 is provided at the tip of the filling hose 15, and a filling nozzle 16 is provided in the housing 2. There is provided a nozzle hook 17 for hanging. The inflow pipe 5 is connected to a supply pipe 19 from a gas supply source 18 such as a gas tank.

なお、流量計９、１３は口径３ｍｍ程度であり、従来から安価に量産されている耐圧流量計が使用されている。また、遮断弁８、１２は口径３ｍｍ程度であり、従来から安価に量産されている耐圧式のものが使用されている。そして、各配管５、６、１０、１４、１９及び充填ホース１５は内径７ｍｍ程度であり、従来から安価に量産されている耐圧管及び耐圧ホースが使用されている。   The flow meters 9 and 13 have a diameter of about 3 mm, and pressure-resistant flow meters that are conventionally mass-produced at low cost are used. Further, the shut-off valves 8 and 12 have a diameter of about 3 mm, and pressure-resistant types that are conventionally mass-produced at low cost are used. The pipes 5, 6, 10, 14, 19 and the filling hose 15 have an inner diameter of about 7 mm, and pressure-resistant pipes and pressure-resistant hoses that have been mass-produced at low cost are used.

制御機構４の制御装置２０には、流量計９、１３の流量信号、及びノズル掛け１７に設けられているノズルスイッチ２１のオン・オフ信号が入力し、流量調整弁２６へ開度信号が、遮断弁８、１２へ開閉信号が出力される。   The control device 20 of the control mechanism 4 receives the flow signals of the flow meters 9 and 13 and the on / off signal of the nozzle switch 21 provided on the nozzle hook 17, and the opening degree signal is supplied to the flow rate adjustment valve 26. An open / close signal is output to the shutoff valves 8 and 12.

さらに、充填選択スイッチ２２から選択信号が制御装置２０に入力し、制御装置２０から流量表示信号が表示器２３へ、作動信号が報知器２４へ入力するようになっている。そして、事務所等にＰＯＳ２５が設けられ、制御装置２０はＰＯＳ２５と制御信号を授受するようになっている。   Further, a selection signal is input from the filling selection switch 22 to the control device 20, a flow rate display signal is input from the control device 20 to the display device 23, and an operation signal is input to the alarm device 24.

そして、上述した充填機構３と制御機構４はハウジング２に２組が組み込まれ、同時に２台の自動車へガスを充填できるようになっている。なお、各機器の機能は同様であるので、説明は省略する。   Two sets of the above-described filling mechanism 3 and control mechanism 4 are incorporated in the housing 2 so that gas can be filled in two automobiles at the same time. In addition, since the function of each apparatus is the same, description is abbreviate | omitted.

このように小流量では１個の流量計を使用して充填し、大流量では２個の流量計を使用して充填するので、小流量でも大流量でも計量精度が良いガス充填装置となる。また、安価な流量計が使用できるので、安価なガス充填装置となる。   As described above, the small flow rate is filled by using one flow meter, and the large flow rate is filled by using two flow meters. Therefore, the gas filling device has a good measurement accuracy at both the small flow rate and the large flow rate. Moreover, since an inexpensive flowmeter can be used, it becomes an inexpensive gas filling apparatus.

この実施の形態では口径が比較的大きい１個の流量調整弁２６を使用しており、即ち、流入管５に流量制御弁２６を介装し、流量制御弁２６の吐出側を分岐している。このように流量制御弁２６を１個で構成する事により、安価なガス充填装置とすることができる。   In this embodiment, one flow rate adjusting valve 26 having a relatively large diameter is used, that is, the flow rate control valve 26 is interposed in the inflow pipe 5 and the discharge side of the flow rate control valve 26 is branched. . Thus, by comprising the flow control valve 26 by one, it can be set as an inexpensive gas filling apparatus.

次に、図２の制御フロー図に基づいて、燃料電池自動車へ水素ガスを充填する態様を説明する。   Next, an aspect of filling the fuel cell vehicle with hydrogen gas will be described based on the control flow diagram of FIG.

（１） 乗用車、小型トラック等の燃料電池自動車へ水素ガスを充填する場合
ノズル掛け１７から充填ノズル１６を外し、充填ノズル１６を燃料自動車の燃料タンクに接続する。充填ノズル１６をノズル掛け１７から外すと、ノズルスイッチ２１からオン信号が制御装置２０に入力する（ＳＴ２１）。燃料電池自動車は小型であるので、充填選択スイッチ２２の「標準」釦２２ａを押すと（ＳＴ２２）、制御装置２０は流量調整弁２６を標準開度にし、遮断弁８を開く（ＳＴ２３）。 (1) When filling a fuel cell vehicle such as a passenger car or a small truck with hydrogen gas Remove the filling nozzle 16 from the nozzle hook 17 and connect the filling nozzle 16 to the fuel tank of the fuel vehicle. When the filling nozzle 16 is removed from the nozzle hook 17, an ON signal is input from the nozzle switch 21 to the control device 20 (ST21). Since the fuel cell vehicle is small, when the “standard” button 22a of the filling selection switch 22 is pressed (ST22), the control device 20 sets the flow rate adjustment valve 26 to the standard opening and opens the shut-off valve 8 (ST23).

遮断弁８が開くと、ガス供給源１８の水素ガスは、供給管１９、流入管５、流量調整弁２６、分岐管６、遮断弁８、流量計９、流出管１４、及び充填ホース１５を介して充填ノズル１６から燃料自動車の燃料タンクに充填される。充填により生じる流量計９の流量信号は制御装置２０に入力し（ＳＴ２４）、流量信号は制御装置２０で計数されて表示器２３に表示される（ＳＴ２５）。燃料タンクが満タンになり充填が終わると（ＳＴ２６）、制御装置２０は遮断弁８を閉じ、報知器２４を作動して充填終了を報知する（ＳＴ２７）。   When the shutoff valve 8 is opened, the hydrogen gas from the gas supply source 18 passes through the supply pipe 19, the inflow pipe 5, the flow rate adjustment valve 26, the branch pipe 6, the shutoff valve 8, the flow meter 9, the outflow pipe 14, and the filling hose 15. Then, the fuel tank of the fuel vehicle is filled from the filling nozzle 16. The flow rate signal of the flow meter 9 generated by filling is input to the control device 20 (ST24), and the flow rate signal is counted by the control device 20 and displayed on the display 23 (ST25). When the fuel tank is full and filling is completed (ST26), the control device 20 closes the shut-off valve 8 and operates the notification device 24 to notify the completion of filling (ST27).

報知器２４の作動により充填終了を知った作業者は、充填ノズル１６を燃料タンクから外してノズル掛け１７に掛ける。充填ノズル１６をノズル掛け１７に掛けることによりノズルスイッチ２１からオフ信号が制御装置２０に入力し（ＳＴ２８）、ＰＯＳ２５から充填伝票が発行され（ＳＴ２９）、この充填伝票に基づいて精算をする。   An operator who knows the end of filling by operating the alarm 24 removes the filling nozzle 16 from the fuel tank and places it on the nozzle hook 17. By applying the filling nozzle 16 to the nozzle hook 17, an off signal is input from the nozzle switch 21 to the control device 20 (ST28), a filling slip is issued from the POS 25 (ST29), and settlement is performed based on this filling slip.

（２） バス、大型トラック等の燃料電池自動車へ水素ガスを充填する場合
ノズル掛け１７から充填ノズル１６を外し、充填ノズル１６を燃料自動車の燃料タンクに接続する。充填ノズル１６をノズル掛け１７から外すと、ノズルスイッチ２１からオン信号が制御装置２０に入力する（ＳＴ２１）。燃料電池自動車は大型であるので、充填選択スイッチ２２の「高速」釦２２ｂを押すと（ＳＴ３０）、制御装置２０は流量調整弁２６を高速開度にし、遮断弁８、１２を開く（ＳＴ３１）。 (2) When filling a fuel cell vehicle such as a bus or a large truck with hydrogen gas Remove the filling nozzle 16 from the nozzle hook 17 and connect the filling nozzle 16 to the fuel tank of the fuel vehicle. When the filling nozzle 16 is removed from the nozzle hook 17, an ON signal is input from the nozzle switch 21 to the control device 20 (ST21). Since the fuel cell vehicle is large, when the “high speed” button 22b of the filling selection switch 22 is pressed (ST30), the control device 20 opens the flow rate adjustment valve 26 at a high speed and opens the shutoff valves 8 and 12 (ST31). .

遮断弁８、１２が開くと、ガス供給源１８の水素ガスは、供給管１９、流入管５、流量調整弁２６、分岐管６、１０、遮断弁８、１２、流量計９、１３、流出管１４、及び充填ホース１５を介して充填ノズル１６から燃料自動車の燃料タンクに充填される。 充填により生じる流量計９、１３の流量信号は制御装置２０に入力し（ＳＴ２４）、流量信号は制御装置２０で計数され、各流量計の計数値を合算して表示器２３に表示される（ＳＴ２５）。   When the shutoff valves 8 and 12 are opened, the hydrogen gas from the gas supply source 18 is supplied from the supply pipe 19, the inflow pipe 5, the flow rate adjustment valve 26, the branch pipes 6 and 10, the shutoff valves 8 and 12, the flow meters 9 and 13, and the outflow. The fuel tank of the fuel vehicle is filled from the filling nozzle 16 through the pipe 14 and the filling hose 15. The flow signals of the flow meters 9 and 13 generated by filling are input to the control device 20 (ST24), the flow signals are counted by the control device 20, and the count values of the respective flow meters are added together and displayed on the display 23 ( ST25).

燃料タンクが満タンになり充填が終わると（ＳＴ２６）、制御装置２０は遮断弁８、１２を閉じ、報知器２４を作動して充填終了を報知する（ＳＴ２７）。報知器２４の作動により充填終了を知った作業者は、充填ノズル１６を燃料タンクから外してノズル掛け１７に掛ける。充填ノズル１６をノズル掛け１７に掛けることによりノズルスイッチ２１からオフ信号が制御装置２０に入力し（ＳＴ２８）、ＰＯＳ２５から充填伝票が発行され（ＳＴ２９）、この充填伝票に基づいて精算をする。   When the fuel tank is full and filling is completed (ST26), the control device 20 closes the shut-off valves 8 and 12, and operates the alarm 24 to notify the end of filling (ST27). An operator who knows the end of filling by operating the alarm 24 removes the filling nozzle 16 from the fuel tank and places it on the nozzle hook 17. By applying the filling nozzle 16 to the nozzle hook 17, an off signal is input from the nozzle switch 21 to the control device 20 (ST28), a filling slip is issued from the POS 25 (ST29), and settlement is performed based on this filling slip.

なお、上記実施の形態のガス充填装置では２個の遮断弁を使用しているが、口径が大きい遮断弁を使用することにより１個とすることができる。即ち、流入管に１個の流量制御弁及び遮断弁を介装し、遮断弁の吐出側を分岐し、この分岐管にそれぞれ流量計を介装する。このように流量制御弁及び遮断弁をそれぞれ１個で構成する事により、更に安価なガス充填装置とすることができる。   In addition, in the gas filling apparatus of the said embodiment, although two shut-off valves are used, it can be set to one by using a shut-off valve with a large diameter. That is, one flow control valve and a shutoff valve are provided in the inflow pipe, the discharge side of the shutoff valve is branched, and a flow meter is provided in each of the branch pipes. Thus, by comprising one flow control valve and one shut-off valve, a more inexpensive gas filling device can be obtained.

大流量でも小流量でも計量精度良く充填でき、安価なガス充填装置を提供できる。その結果、ガスを燃料として走行する自動車の普及に合わせて、安価なガス充填装置を提供できるようになる。   It is possible to provide an inexpensive gas filling device that can be filled with high accuracy even at a large flow rate or a small flow rate. As a result, an inexpensive gas filling device can be provided in accordance with the spread of automobiles that run on gas as fuel.
