【考案が解決しようとする課題】[Problems to be solved by the device]

ところで、このような従来例にあっては、次の問題が指摘されていた。すなわ ち、上述したようにこの種従来例では、給油される燃料油について、その給油量 は給油配管Ａ中の流量制御弁４により、又、その給油圧力は給油配管Ａ中の圧力 制御弁１により、それぞれ制御，調整されていた。そして流量制御弁４は、コン トローラ１４にて、予め入力設定された給油プリセット量とパルス発振器１３か らの信号に基づく給油積算量とを比較することにより、開閉され、又、圧力制御 弁１は、ベンチュリ５における圧力変化に対応すべく、各種の制御配管や制御弁 等の制御用機器類により、その開閉度が調整されていた。つまり、給油される燃 料油の給油量と給油圧力とは、給油配管Ａに設けられた流量制御弁４と圧力制御 弁１により、つまり別々に独立して設けられた給油機器により、制御，調整され ていた。この種従来例では、このように給油配管Ａ中に、２種類の制御，調整用 の機器を別々に設けていたので、まず、給油機器類全体が大型化すると共に、各 々の取付工数も大きく、又、調整等も複雑でその精度にも不安があり、更に、コ スト面にも問題が指摘されていた。 By the way, in such a conventional example, the following problems have been pointed out. That is, as described above, in this type of conventional example, regarding the fuel oil to be refueled, the refueling amount is controlled by the flow control valve 4 in the refueling pipe A, and the refueling pressure is controlled by the pressure control valve in the refueling pipe A. 1 was controlled and adjusted respectively. Then, the flow rate control valve 4 is opened and closed by the controller 14 by comparing the preset oil supply preset amount and the oil supply integrated amount based on the signal from the pulse oscillator 13, and the pressure control valve 1 In order to respond to the pressure change in the Venturi 5, the degree of opening and closing of the Venturi 5 was adjusted by various control pipes, control valves and other control devices. That is, the amount of fuel oil to be refueled and the refueling pressure are controlled by the flow rate control valve 4 and the pressure control valve 1 provided in the refueling pipe A, that is, by the refueling equipment separately and independently provided, It was adjusted. In the conventional example of this kind, since two kinds of control and adjustment devices are separately provided in the oil supply pipe A, the size of the entire oil supply device is increased, and the number of man-hours for each installation is also increased. It was large and complicated to adjust, so there was concern about its accuracy, and there were also problems with cost.

【０００４】 本考案は、このような実情に鑑み、上記従来例の問題点を解決すべくなされた ものであって、給油配管の流量制御弁の入口側と出口側間に、絞り弁，電磁弁， 圧力制御弁等を備えた制御回路を付設し、流量制御弁の開閉を、コントローラを 介し制御回路の電磁弁にて行うと共に、流量制御弁の開閉度を、ベンチュリを介 し制御回路の圧力制御弁にて調整するようにしたことにより、給油される燃料油 の給油量の制御と給油圧力の調整とが、流量制御弁という１つの給油機器により 、給油配管の１箇所で実施される、燃料給油車の給油制御装置を提案することを 目的とする。In view of such circumstances, the present invention has been made to solve the problems of the above-mentioned conventional example, in which a throttle valve and an electromagnetic valve are provided between the inlet side and the outlet side of the flow control valve of the oil supply pipe. A control circuit equipped with a valve, pressure control valve, etc. is attached, and the flow control valve is opened / closed by the solenoid valve of the control circuit via the controller, and the opening / closing degree of the flow control valve is controlled via the venturi. By adjusting with the pressure control valve, the control of the amount of fuel oil to be refueled and the adjustment of the refueling pressure are performed at one location on the refueling pipe by one refueling device called a flow control valve. The purpose is to propose a refueling control device for a fuel refueling vehicle.

【実施例】【Example】

以下本考案を、図面に示すその実施例に基づいて、詳細に説明する。図１は本 考案の実施例の説明図、図２は同実施例の概略説明図である。なお図４はサービ サの概略側面図である。 The present invention will be described in detail below based on the embodiments shown in the drawings. FIG. 1 is an explanatory view of an embodiment of the present invention, and FIG. 2 is a schematic explanatory view of the embodiment. 4 is a schematic side view of the servicer.

【０００８】 図１の実施例では、燃料給油車の１例としてサービサが示されている。このサ ービサでは燃料油を、フィルター２，計量器３，流量制御弁１７，ベンチュリ５ 等の給油機器類が順に配された給油配管Ｄを経た後、給油ホースＢにて航空機に 給油する。まず、これらについて詳述すると、空港にはハイドラント給油装置（ 図示せず）が設けられており、その貯留タンクからポンプにて圧送された燃料油 は、ハイドラント配管１５を介し、地下ピット給油口のハイドラントバルブ１６ に至る。そして、サービサに車載されていたインテークホースＣの先端が、ハイ ドラントカプラ６を介しハイドラントバルブ１６に接続されることにより、圧送 されてきた燃料油は、このインテークホースＣそしてスイベルジョイント７を介 し、サービサの機械室Ｍ（図４参照）の給油配管Ｄへと取り入れられる。In the embodiment shown in FIG. 1, a servicer is shown as an example of a fuel refueling vehicle. In this servicer, fuel oil is supplied to the aircraft by a refueling hose B after passing through a refueling pipe D in which refueling devices such as a filter 2, a meter 3, a flow control valve 17, and a venturi 5 are sequentially arranged. First, to explain these in detail, a hydrant refueling device (not shown) is installed at the airport, and the fuel oil pumped from the storage tank of the hydrant refueling device passes through the hydrant pipe 15 and is supplied to the underground pit refueling port. Up to the hydrant valve 16. Then, the tip of the intake hose C mounted on the servicer is connected to the hydrant valve 16 via the hydrant coupler 6, so that the fuel oil that has been pressure-fed is passed through the intake hose C and the swivel joint 7. It is taken into the oil supply pipe D of the machine room M (see FIG. 4) of the servicer.

【０００９】 機械室Ｍの給油配管Ｄには、上流側から下流側に向け、閉止弁８，ストレーナ ９，フィルター２，計量器３，流量制御弁１７，ベンチュリ５等の給油機器類が 、順に設けられている。そこで取り入れられた燃料油は、給油配管Ｄの上流側の 閉止弁８を経た後、付設された圧力計１８にてイン圧力が検出表示され、次に、 ストレーナ９やフィルターセパレータであるフィルター２にて濾過され清浄化さ れる。それから燃料油は、計量器３を通過するが、計量器３には流量に応じたパ ルス信号を発生するパルス発振器１３と、積算カウンタ１２が付設されている。 そして燃料油は、流量制御弁１７に至り、後述により給油量の制御と給油圧力の 調整とが行われた後、ベンチュリ５にて最終的な給油圧力が形成，測定され、給 油配管Ｄの下流側において、付設された圧力計１９にてアウト圧力が検出表示さ れる。In the oil supply pipe D of the machine room M, in order from the upstream side to the downstream side, the stop valve 8, the strainer 9, the filter 2, the meter 3, the flow control valve 17, the oil supply equipment such as the venturi 5 are sequentially provided. It is provided. The fuel oil taken therein passed through the shutoff valve 8 on the upstream side of the oil supply pipe D, and then the in-pressure was detected and displayed by the attached pressure gauge 18, and then the strainer 9 and the filter 2 which is a filter separator were displayed. Filtered and cleaned. Then, the fuel oil passes through the measuring device 3. The measuring device 3 is provided with a pulse oscillator 13 for generating a pulse signal according to the flow rate and an integrating counter 12. Then, the fuel oil reaches the flow control valve 17, and after the refueling amount is controlled and the refueling pressure is adjusted as described below, the venturi 5 forms and measures the final refueling pressure, and the fuel pipe D On the downstream side, the attached pressure gauge 19 detects and displays the out pressure.

【００１０】 このような給油配管Ｄの各種の給油機器類を経た後、燃料油は、スイベルジョ イント１０から給油ホースＢを介し、その先端のノズル１１にて航空機に給油さ れることになる。すなわち、サービサの給油配管Ｄや給油機器類が収納された機 械室Ｍの後部には、リフト機構Ｎにて昇降自在に給油作業台Ｓが組み付けられて おり（図４参照）、給油作業台Ｓは、給油時には作業員を載せて航空機の給油口 （図示せず）の直下まで上昇され、作業員は、車載されていた給油ホースＢの先 端のノズル１１を、航空機の給油口に接続して給油作業を行う。図４中Ｔは、給 油作業台Ｓへの昇降梯子である。なお航空機側の燃料タンクは、一般に複数のタ ンク室に分割されており、各々のタンク室は、それぞれの元弁を介し集合配管に 連通され、集合配管の一端に給油口が設けられている（図示せず）。そしてこの 各タンク室の元弁は、給油に際し自動又は手動にて開放され、一定量の給油が完 了すると閉鎖される。After passing through various kinds of refueling equipment of the refueling pipe D, the fuel oil is refueled from the swivel joint 10 through the refueling hose B to the aircraft by the nozzle 11 at the tip thereof. That is, at the rear part of the machine room M in which the servicer's refueling pipe D and refueling equipment are housed, a refueling work table S is mounted so that it can be raised and lowered by a lift mechanism N (see FIG. 4). At the time of refueling, S is lifted up to just below an oil filler port (not shown) of the aircraft when refueling, and the worker connects the nozzle 11 at the tip of the vehicle-mounted refueling hose B to the aircraft oil filler port. And refuel. In FIG. 4, T is an elevating ladder to the refueling workbench S. Note that the fuel tank on the aircraft side is generally divided into a plurality of tank chambers, and each tank chamber is connected to the collective pipe via each source valve, and a fuel filler port is provided at one end of the collective pipe. (Not shown). The main valve of each tank chamber is opened automatically or manually at the time of refueling, and is closed when a certain amount of refueling is completed.

【００１１】 さて、この燃料給油車には給油制御装置２０が設けられており、以下、この給 油制御装置２０について詳述する。この給油制御装置２０は、上述した給油配管 Ｄに設けられた流量制御弁１７の入口側２１と出口側２２間に形成された制御回 路Ｅと、制御回路Ｅに順に設けられた絞り弁２３，第１電磁弁２４，第２電磁弁 ２５，圧力制御弁２６と、コントローラ２７と、を有してなる。A refueling control device 20 is provided in the fuel refueling vehicle. The refueling control device 20 will be described in detail below. The refueling control device 20 includes a control circuit E formed between an inlet side 21 and an outlet side 22 of a flow rate control valve 17 provided in the above-described refueling pipe D, and a throttle valve 23 sequentially provided in a control circuit E. , A first solenoid valve 24, a second solenoid valve 25, a pressure control valve 26, and a controller 27.

【００１２】 まず流量制御弁１７は、そのケーシング２８の略中央に弁体収納部２９が斜め に突出形成されており、この弁体収納部２９に弁体３０が配され、弁体３０の移 動により、開閉され開閉度が調整される。弁体３０の弁軸３１には、スプリング ３２が介裝され常閉方向に弁体３０を付勢しており、又、弁軸３１の弁体収納部 ２９外の後端には、リミットスイッチ３３が対向設され、弁体３０の所定開度を 検出するようになっている。そして、このような流量制御弁１７の入口側２１と 出口側２２、つまり弁体３０を中心にその上流側と下流側のケーシング２８に、 制御回路Ｅの上流端と下流端がそれぞれ開口している。又、制御回路Ｅの第１電 磁弁２４と第２電磁弁２５の中間と、流量制御弁１７の弁体収納部２９の後部つ まり弁体３０の後側との間には、補助回路Ｆが設けられている。そして、補助回 路Ｆの流量制御弁１７寄りには、逆止弁付絞り弁３４が設けられ、又、制御回路 Ｅと補助回路Ｆとは、途中でサージ圧力制御弁３５および第３電磁弁３６を介し 、それぞれ接続されている。First, in the flow rate control valve 17, a valve body storage portion 29 is formed so as to project obliquely in a substantially central portion of a casing 28 thereof. The valve body 30 is arranged in the valve body storage portion 29, and the valve body 30 is moved. Depending on the movement, it is opened and closed to adjust the degree of opening and closing. A spring 32 is interposed on the valve shaft 31 of the valve body 30 to urge the valve body 30 in a normally closed direction. Further, a limit switch is provided at the rear end of the valve shaft 31 outside the valve body storage portion 29. 33 are provided so as to face each other and detect a predetermined opening degree of the valve body 30. The upstream side and the downstream side of the control circuit E are opened to the inlet side 21 and the outlet side 22 of the flow control valve 17 described above, that is, the casing 28 on the upstream side and the downstream side of the valve body 30. There is. In addition, an auxiliary circuit is provided between the first electromagnetic valve 24 and the second electromagnetic valve 25 of the control circuit E and the rear side of the valve body accommodating portion 29 of the flow control valve 17, that is, the rear side of the valve body 30. F is provided. A throttle valve 34 with a check valve is provided near the flow control valve 17 of the auxiliary circuit F, and the surge pressure control valve 35 and the third solenoid valve are provided on the way between the control circuit E and the auxiliary circuit F. They are connected via 36 respectively.

【００１３】 第１電磁弁２４，第２電磁弁２５，第３電磁弁３６等は、コントローラ２７か らの開閉信号にて開閉され、第１電磁弁２４および第２電磁弁２５は常閉に、第 ３電磁弁３６は常開に設定されている。又、レジューシングパイロットバルブで ある圧力制御弁２６は、勿論常開に設定され、ベンチュリ５における圧力変化に 対応して、その絞り度が調整される。又、リリーフパイロットバルブであるサー ジ圧力制御弁３５は常閉に設定され、ベンチュリ５における急激な圧力変化つま りサージ圧力発生に伴い、開とされる。The first solenoid valve 24, the second solenoid valve 25, the third solenoid valve 36, etc. are opened / closed by an opening / closing signal from the controller 27, and the first solenoid valve 24 and the second solenoid valve 25 are normally closed. The third solenoid valve 36 is normally open. The pressure control valve 26, which is a reducing pilot valve, is of course set to the normally open state, and the degree of throttling is adjusted according to the pressure change in the venturi 5. Further, the surge pressure control valve 35, which is a relief pilot valve, is set to be normally closed, and is opened in response to a sudden pressure change in the venturi 5 or a surge pressure.

【００１４】 そしてまず、給油開始に際しては、制御回路Ｅと補助回路Ｆ間のサージ圧力制 御弁３５は閉のまま、第３電磁弁３６は閉に切り換えられ、制御回路Ｅの第１電 磁弁２４および第２電磁弁２５は開に切り換えられ、圧力制御弁２６は勿論開の ままとなっている。他方、給油配管Ｄの流量制御弁１７は閉で、その弁体３０も 閉であるので、燃料油は、流量制御弁１７の入口側２１から、制御回路Ｅを介し 流量制御弁１７の出口側２２へと迂回して流れる。その際、燃料油は絞り弁２３ を通過し、その上流側と下流側間に圧力差が生じるので、流量制御弁１７におい て、入口側２１の圧力が、弁体収納部２９の弁体３０の後側の圧力より高圧とな り、弁体３０をスプリング３２の付勢力に抗して開に押動し、もって流量制御弁 １７は開となり、給油配管Ｄ中を燃料油が流れるようになる。これに対し給油終 了に際しては、第１電磁弁２４および第２電磁弁２５を閉、第３電磁弁３６を開 に切り換えする。すると流量制御弁１７の入口側２１から分岐流入した一部の燃 料油は、制御回路Ｅを一部介した後、開の第３電磁弁３６，補助回路Ｆ，逆止弁 付絞り弁３４を通って、流量制御弁１７の弁体収納部２９に至り、弁体３０の後 側に流入するので、スプリング３２の付勢力も加わり弁体３０が開から閉に押動 され、もって流量制御弁１７は閉となり、給油配管Ｄ中の燃料油の流れが遮断さ れる。このように、制御回路Ｅの第１電磁弁２４，第２電磁弁２５，第３電磁弁 ３６等の開閉により、給油配管Ｄの流量制御弁１７を開閉可能となっている。First, at the start of refueling, the surge pressure control valve 35 between the control circuit E and the auxiliary circuit F remains closed, and the third solenoid valve 36 is switched to the closed state. The valve 24 and the second solenoid valve 25 are switched to open, and the pressure control valve 26 is of course left open. On the other hand, since the flow control valve 17 of the oil supply pipe D is closed and the valve body 30 is also closed, fuel oil flows from the inlet side 21 of the flow control valve 17 through the control circuit E to the outlet side of the flow control valve 17. It detours to 22 and flows. At that time, the fuel oil passes through the throttle valve 23, and a pressure difference is generated between the upstream side and the downstream side of the throttle valve 23. Therefore, in the flow control valve 17, the pressure on the inlet side 21 is equal to that on the valve body 30 The pressure becomes higher than the pressure on the rear side, and the valve body 30 is pushed open against the biasing force of the spring 32, so that the flow control valve 17 is opened and fuel oil flows in the oil supply pipe D. Become. On the other hand, at the end of refueling, the first solenoid valve 24 and the second solenoid valve 25 are closed and the third solenoid valve 36 is switched to open. Then, a part of the fuel oil branched from the inlet side 21 of the flow control valve 17 partially passes through the control circuit E, and then the third solenoid valve 36 that is opened, the auxiliary circuit F, and the throttle valve with a check valve 34. Through to the valve body accommodating portion 29 of the flow control valve 17 and flow into the rear side of the valve body 30, the urging force of the spring 32 is also applied to push the valve body 30 from open to closed, thereby controlling the flow rate. The valve 17 is closed, and the flow of fuel oil in the oil supply pipe D is shut off. In this way, the flow control valve 17 of the oil supply pipe D can be opened and closed by opening and closing the first solenoid valve 24, the second solenoid valve 25, the third solenoid valve 36, etc. of the control circuit E.

【００１５】 次に圧力制御弁２６は、ベンチュリ５における圧力変化に対応してその絞り度 が調整されるが、これにより、給油配管Ｄの流量制御弁１７の開閉度を調整可能 となっている。すなわち、給油中に給油圧力が所定値以上に上昇すると、ベンチ ュリ５における圧力変化に基づき、圧力制御弁２６のダイヤフラムが絞り方向に 押動され、圧力制御弁２６が絞られる。すると、流量制御弁１７の入口側２１か ら分岐流入した一部の燃料油は、この絞られた分だけ、制御回路Ｅの第１電磁弁 ２４と第２電磁弁２５間から、補助回路Ｆ，逆止弁付絞り弁３４を通って、流量 制御弁１７の弁体収納部２９に至り、弁体３０の後側に流入するので、弁体３０ が、スプリング３２の付勢力も加わり開から閉側に向け所定量だけ押動され、も って流量制御弁１７の開閉度が、より閉に調整されて予め設定した圧力となるよ う、給油配管Ｄ中の燃料油の流れが絞られ、給油圧力が所定値まで下げられる。Next, the degree of throttling of the pressure control valve 26 is adjusted in accordance with the pressure change in the venturi 5, whereby the opening / closing degree of the flow control valve 17 of the oil supply pipe D can be adjusted. . That is, when the refueling pressure rises above a predetermined value during refueling, the diaphragm of the pressure control valve 26 is pushed in the throttle direction based on the pressure change in the bench 5, and the pressure control valve 26 is throttled. Then, a part of the fuel oil branched and flown in from the inlet side 21 of the flow rate control valve 17 is squeezed by the throttled portion from between the first electromagnetic valve 24 and the second electromagnetic valve 25 of the control circuit E to the auxiliary circuit F. ， Through the check valve with check valve 34, it reaches the valve body storage portion 29 of the flow control valve 17 and flows into the rear side of the valve body 30, so that the valve body 30 is also opened by the urging force of the spring 32. The flow of the fuel oil in the oil supply pipe D is throttled so that the flow control valve 17 is pushed toward the closing side by a predetermined amount, and the opening / closing degree of the flow control valve 17 is adjusted to be more closed to a preset pressure. The refueling pressure is reduced to a predetermined value.

【００１６】 又、サージ圧力制御弁３５は、給油中における給油圧力の急激な変化、つまり 給油配管Ｄにおけるサージ圧力発生に伴い開とされ、給油配管Ｄの流量制御弁１ ７を直ちに閉とし、給油配管Ｄ中の燃料油の流れを遮断する。すなわちこの場合 には、ベンチュリ５における急激な圧力変化に基づき制御回路Ｅと補助回路Ｆ間 のサージ圧力制御弁３５が閉から開に切り換えられ、流量制御弁１７の入口側２ １から分岐流入した一部の燃料油は、絞り弁２３側ではなく、制御回路Ｅから開 のサージ圧力制御弁３５を介し、直ちに補助回路Ｆ，逆止弁付絞り弁３４を通っ て、流量制御弁１７の弁体収納部２９に至る。そして、弁体３０の後側に流入し て、弁体３０をスプリング３２の付勢力も加わって閉に押動するので、直ちに、 流量制御弁１７は閉となり、給油配管Ｄ中の燃料油の流れが遮断される。The surge pressure control valve 35 is opened in response to a sudden change in the oil supply pressure during refueling, that is, when surge pressure is generated in the oil supply pipe D, and the flow control valve 17 of the oil supply pipe D is immediately closed. The flow of fuel oil in the oil supply pipe D is shut off. That is, in this case, the surge pressure control valve 35 between the control circuit E and the auxiliary circuit F is switched from closed to open based on the abrupt pressure change in the venturi 5, and the flow-in is branched from the inlet side 21 of the flow control valve 17. Some of the fuel oil flows through the surge pressure control valve 35 opened from the control circuit E, not through the throttle valve 23 side, immediately through the auxiliary circuit F and the throttle valve with check valve 34, and then through the valve of the flow control valve 17. It reaches the body storage section 29. Then, it flows into the rear side of the valve body 30 and pushes the valve body 30 to the close by applying the urging force of the spring 32, so that the flow control valve 17 is immediately closed and the fuel oil in the oil supply pipe D is closed. The flow is cut off.

【００１７】 なお、図１中３７，３８はそれぞれサージタンクである。これらのサージタン ク３７，３８も、上述のサージ圧力の対策用として設けられており、まず、サー ジタンク３７は、給油配管Ｄの下流側のベンチュリ５と圧力計１９間から、閉止 弁３９を介し分岐接続され、又、サージタンク３８は、給油配管Ｄの上流側のス トレーナ９とフィルター２間から、閉止弁４０を介し分岐接続されている。そし て下流側のサージタンク３８は、サージ圧力発生に際しまず最初に、給油配管Ｄ からこれを吸収すべく機能し、次に上述したごとく、サージ圧力制御弁３５にて 給油配管Ｄの流量制御弁１７を閉とする対策が講じられることになる。なおサー ジタンク３８は、このような場合に流量制御弁１７が急激に閉とされるので、そ の際、副次的に給油配管Ｄに発生する衝撃圧を吸収すべく機能する。なお図１中 、４１はベンチュリ５に付設された圧力計、４２はフィルター２に付設された差 圧計、４３は電気配線である。In FIG. 1, 37 and 38 are surge tanks, respectively. These surge tanks 37 and 38 are also provided as countermeasures against the above surge pressure. First, the surge tank 37 is provided between the venturi 5 on the downstream side of the oil supply pipe D and the pressure gauge 19 via the shutoff valve 39. The surge tank 38 is branched and connected between the strainer 9 on the upstream side of the oil supply pipe D and the filter 2 through a stop valve 40. When the surge pressure is generated, the surge tank 38 on the downstream side first functions to absorb the surge pressure from the oil supply pipe D. Then, as described above, the surge pressure control valve 35 is used to control the flow control valve of the oil supply pipe D. Measures to close 17 will be taken. Since the flow control valve 17 is rapidly closed in such a case, the surge tank 38 functions to absorb the impact pressure secondary to the oil supply pipe D at that time. In FIG. 1, 41 is a pressure gauge attached to the venturi 5, 42 is a differential pressure gauge attached to the filter 2, and 43 is electrical wiring.

【００１８】 さてコントローラ２７は、マイクロコンピュータを内蔵すると共に、表示部と キーボードを備えてなる。そしてコントローラ２７は、まず、予め入力された給 油プリセット量と計量器３からの信号に基づき演算される給油積算量との比較に 基づき、第１電磁弁２４，第２電磁弁２５，第３電磁弁３６等に対し、開閉信号 を出力する。すなわちコントローラ２７には、給油に際し予め、目標値たる給油 プリセット量が設定入力されて記憶されると共に、給油中において順次、計量器 ３に付設されたパルス発振器１３から流量に応じたパルス信号が送出され、コン トローラ２７では、このようなパルス信号に基づき現在値たる給油積算量が演算 され、表示部に表示されると共に、上述した目標値たる給油プリセット量とこの 現在値たる給油積算量とが比較される。そしてコントローラ２７からは、まず給 油開始時において、第１電磁弁２４および第２電磁弁２５に対し開信号、第３電 磁弁３６に対し閉信号が出力され、又、上述した給油プリセット量と給油積算量 が一致した場合には、給油を終了すべく、第１電磁弁２４および第２電磁弁２５ に対し閉信号が、第３電磁弁３６に対し開信号が出力される。なおこのコントロ ーラ２７は、給油作業台Ｓ（図４参照）上に配されているので、給油プリセット 量の追加等の変更があった場合も、作業員は地上へ降りることなく給油作業台Ｓ 上で容易に対応可能である。The controller 27 includes a microcomputer, a display section, and a keyboard. Then, the controller 27 firstly, based on the comparison between the pre-input refueling preset amount and the refueling integrated amount calculated based on the signal from the measuring device 3, the first solenoid valve 24, the second solenoid valve 25, and the third solenoid valve 25. An open / close signal is output to the solenoid valve 36 and the like. In other words, the controller 27 stores and presets a preset amount of refueling, which is a target value, at the time of refueling, and sequentially outputs a pulse signal corresponding to the flow rate from the pulse oscillator 13 attached to the measuring instrument 3 during refueling. Then, the controller 27 calculates the refueling integrated amount that is the current value based on such a pulse signal and displays it on the display unit, and at the same time, displays the above-mentioned target refueling preset amount and the refueling integrated amount that is the current value. Be compared. The controller 27 outputs an open signal to the first solenoid valve 24 and the second solenoid valve 25 and a close signal to the third solenoid valve 36 at the start of refueling. And the integrated amount of refueling match, a close signal is output to the first solenoid valve 24 and the second solenoid valve 25 and an open signal is output to the third solenoid valve 36 in order to end refueling. Since the controller 27 is arranged on the refueling workbench S (see FIG. 4), the worker does not have to go down to the ground even if the refueling preset amount is changed or the like. It can be easily handled on S.

【００１９】 なお図示実施例の場合には、給油終了に際し、２段階の制御が行われるように なっている。すなわち、コントローラ２７には予め、１段階目として、正式の給 油プリセット量より若干少ない予備の給油プリセット量が設定されると共に、２ 段階目として、正式の給油プリセット量が設定される。In the case of the illustrated embodiment, two-step control is performed at the end of refueling. That is, in the controller 27, a preliminary refueling preset amount that is slightly smaller than the official refueling preset amount is set in advance as the first step, and an official refueling preset amount is set in the second step.

【００２０】 そして給油が進み、まず予備の給油プリセット量に給油積算量が達すると、次 の第１段階目の制御が実施される。すなわちコントローラ２７から、第１電磁弁 ２４および第２電磁弁２５に対し閉信号が、第３電磁弁３６に対し開信号が出力 され、第１電磁弁２４および第２電磁弁２５を閉、第３電磁弁３６を開に切り換 え、前述したように、流量制御弁１７の入口側２１から分岐流入した一部の燃料 油が、制御回路Ｅ，開の第３電磁弁３６，補助回路Ｆ等を介し、弁体３０の後側 に流入して弁体３０を押動するので、弁体３０は、このような押動とスプリング ３２の付勢力により開から閉側に向け移動を開始する。そして弁体３０が所定量 だけ移動し、流量制御弁１７の開閉度が、予め設定した所定開度まで閉に調整さ れると、リミットスイッチ３３がこれを検出し、その検出信号がコントローラ２ ７に送出される。すると、コントローラ２７から第３電磁弁３６に対し閉信号が 出力され、直ちに第３電磁弁３６が閉に切り換わるので、燃料油が補助回路Ｆに 流れず弁体３０を押動しなくなり、弁体３０が上述した所定量の移動位置で停止 し、流量制御弁１７は上述した所定開度を維持する。このようにして、給油配管 Ｄを流れる燃料油について、流れが絞られ給油流速が低速となる。Then, the refueling progresses, and first, when the cumulative refueling amount reaches the reserve refueling preset amount, the following first stage control is executed. That is, the controller 27 outputs a close signal to the first solenoid valve 24 and the second solenoid valve 25 and an open signal to the third solenoid valve 36 to close the first solenoid valve 24 and the second solenoid valve 25. By switching the third solenoid valve 36 to the open state, as described above, a part of the fuel oil branched and flown in from the inlet side 21 of the flow control valve 17 is controlled by the control circuit E, the third solenoid valve 36 that is open, and the auxiliary circuit F. And the like, the valve body 30 flows into the rear side of the valve body 30 and pushes the valve body 30, so that the valve body 30 starts to move from the open side to the closed side by such pushing force and the biasing force of the spring 32. . When the valve body 30 moves by a predetermined amount and the opening / closing degree of the flow rate control valve 17 is adjusted to be closed to a preset predetermined opening degree, the limit switch 33 detects this, and the detection signal thereof is output to the controller 27. Sent to. Then, a closing signal is output from the controller 27 to the third solenoid valve 36, and the third solenoid valve 36 is immediately closed, so that the fuel oil does not flow to the auxiliary circuit F and the valve body 30 is not pushed, so that the valve is closed. The body 30 stops at the above-mentioned predetermined movement position, and the flow control valve 17 maintains the above-mentioned predetermined opening degree. In this way, the fuel oil flowing through the oil supply pipe D is throttled so that the oil supply flow velocity becomes low.

【００２１】 しかる後、更に給油が進み、正式の給油プリセット量に給油積算量が達すると 、次のような第２段階目の制御が実施される。すなわちコントローラ２７から、 第３電磁弁３６に対し再び開信号が出力され、第３電磁弁３６が再度開に切り換 わり、前述したところに準じ燃料油が補助回路Ｆに流れ、スプリング３２の付勢 力も加わり、弁体３０を停止していた所定量の移動位置から更に閉に押動し、流 量制御弁１７は閉となり、給油配管Ｄ中の燃料油の流れが完全に遮断される。After that, when the refueling further progresses and the cumulative refueling amount reaches the official refueling preset amount, the following second-stage control is performed. That is, the controller 27 outputs the open signal again to the third solenoid valve 36, the third solenoid valve 36 is switched to the open state again, and the fuel oil flows to the auxiliary circuit F in accordance with the above-mentioned point, and the spring 32 is attached. The force is also applied, and the valve body 30 is further pushed from the stopped position of the predetermined amount to the closed position, the flow control valve 17 is closed, and the flow of the fuel oil in the oil supply pipe D is completely shut off.

【００２２】 図示実施例ではこのように、給油の終了に際し２段階の制御が行われ、１段階 目で、流量制御弁１７を一旦絞って給油配管Ｄ中の給油流速を低速とした後、２ 段階目で、流量制御弁１７を完全に閉とし給油配管Ｄを遮断するようになってい る。そこで、流量制御弁１７を一度に開から閉とする場合に比し、正確に給油プ リセット量にて流量制御弁１７が閉となり、正確な給油が実現されると共に、流 量制御弁１７の閉に伴うサージ圧力の発生を押さえることができる、という利点 がある。In the illustrated embodiment, two-step control is thus performed at the end of refueling. In the first step, the flow rate control valve 17 is once throttled to reduce the refueling flow rate in the refueling pipe D, and then 2 At the stage, the flow control valve 17 is completely closed to shut off the oil supply pipe D. Therefore, compared with the case where the flow rate control valve 17 is closed from one time at a time, the flow rate control valve 17 is closed more accurately with the oil supply preset amount, so that accurate oil supply is realized and the flow rate control valve 17 is There is an advantage that the generation of surge pressure due to closing can be suppressed.

【００２３】 本考案の給油制御装置２０は、以上のようになっている。そこで以下のように なる。まず、この燃料給油車の１例であるサービサでは、ハイドラント給油装置 から圧送されてきた燃料油が、フィルター２，計量器３，流量制御弁１７，ベン チュリ５等の給油機器類を備えた給油配管Ｄを経由し、清浄化され所定の給油圧 力で、給油ホースＢにて給油口から航空機の各タンク室に給油される。The refueling control device 20 of the present invention is as described above. Then it becomes as follows. First, in a servicer, which is an example of this fuel refueling vehicle, fuel oil pumped from a hydrant refueling device is refueled with a refueling device such as a filter 2, a meter 3, a flow control valve 17, and a venturi 5. Via the pipe D, the oil is purified and supplied with a predetermined hydraulic pressure from a fuel supply hose B from the fuel supply port to each tank room of the aircraft.

【００２４】 そしてこのサービサでは、給油制御装置２０として、給油配管Ｄの流量制御弁 １７の入口側２１と出口側２２間に、絞り弁２３，第１電磁弁２４，第２電磁弁 ２５，圧力制御弁２６等を備えた制御回路Ｅが付設されており、更に、制御回路 Ｅの途中から分岐され流量制御弁１７の弁体３０の後側に至る補助回路Ｆが形成 され、所定の逆止弁付絞り弁３４，サージ圧力制御弁３５，第３電磁弁３６等が 配されている。又、給油に際しては、まず、給油制御装置２０のコントローラ２ ７に予め給油プリセット量が入力されるが、これと共にコントローラ２７では、 計量器３のパルス発振器１３からのパルス信号に基づき、給油積算量が順次演算 され、この給油プリセット量と給油積算量との比較に基づき、適宜、コントロー ラ２７から制御回路Ｅの第１電磁弁２４，第２電磁弁２５や制御回路Ｅと補助回 路Ｆ間の第３電磁弁３６に対し、開閉信号が出力される。そして、これら第１電 磁弁２４，第２電磁弁２５，第３電磁弁３６等の開閉により、給油配管Ｄの流量 制御弁１７が開閉され、もって、給油される燃料油の給油量が制御されるように なっている。なお図示実施例では、給油プリセット量として、予備の給油プリセ ット量と正式の給油プリセット量との２段階のものが、コントローラ２７に予め 入力される。In this servicer, the refueling control device 20 includes a throttle valve 23, a first solenoid valve 24, a second solenoid valve 25, a pressure regulator between the inlet side 21 and the outlet side 22 of the flow control valve 17 of the oil supply pipe D. A control circuit E including a control valve 26 and the like is additionally provided. Further, an auxiliary circuit F that branches from the middle of the control circuit E to the rear side of the valve body 30 of the flow control valve 17 is formed, and a predetermined check valve is provided. A throttle valve with valve 34, a surge pressure control valve 35, a third solenoid valve 36, etc. are arranged. In addition, at the time of refueling, first, the refueling preset amount is input to the controller 27 of the refueling control device 20 in advance. At the same time, the controller 27 controls the refueling integrated amount based on the pulse signal from the pulse oscillator 13 of the measuring instrument 3. Are calculated sequentially, and based on the comparison between the oil supply preset amount and the oil supply integrated amount, the controller 27 appropriately connects the first solenoid valve 24 and the second solenoid valve 25 of the control circuit E or between the control circuit E and the auxiliary circuit F. An opening / closing signal is output to the third solenoid valve 36 of. Then, the flow control valve 17 of the oil supply pipe D is opened / closed by opening / closing the first electromagnetic valve 24, the second electromagnetic valve 25, the third electromagnetic valve 36, etc., thereby controlling the amount of fuel oil supplied. It is supposed to be done. In the illustrated embodiment, as the refueling preset amount, two levels of the refueling preset amount and the official refueling preset amount are input to the controller 27 in advance.

【００２５】 さて、まず給油開始に際しては、サージ圧力制御弁３５および第３電磁弁３６ は閉で、第１電磁弁２４および第２電磁弁２５は開に設定され、燃料油が、給油 配管Ｄの弁体３０が閉の流量制御弁１７の入口側２１から、制御回路Ｅを介し出 口側２２に至る。そして、絞り弁２３にて燃料油に圧力差が生じ、入口側２１の 圧力が弁体３０の後側の圧力より高圧となるので、弁体３０が開に移動する。と ころで、これにより押圧された弁体３０の後側の燃料油は、逆止弁付絞り弁３４ を備えた補助回路Ｆを介し、第１電磁弁２４と第２電磁弁２５間から制御回路Ｅ へと循環するが、逆止弁付絞り弁３４を介するのでその流れは僅かずつであり、 もって弁体３０もゆっくりと開へと移動する。このように給油開始に際し、流量 制御弁１７は徐々に開となり、急激に開とはならないので、計量器３その他の給 油機器類の破損が防止されるという利点がある。First, at the start of refueling, the surge pressure control valve 35 and the third solenoid valve 36 are set to be closed, the first solenoid valve 24 and the second solenoid valve 25 are set to be open, and the fuel oil is fed to the refueling pipe D. The valve body 30 is closed from the inlet side 21 of the flow control valve 17 to the outlet side 22 via the control circuit E. Then, a pressure difference occurs in the fuel oil at the throttle valve 23, and the pressure on the inlet side 21 becomes higher than the pressure on the rear side of the valve body 30, so that the valve body 30 moves open. The fuel oil on the rear side of the valve body 30 which is pressed by this is controlled from between the first solenoid valve 24 and the second solenoid valve 25 via an auxiliary circuit F having a check valve-equipped throttle valve 34. Although it circulates to the circuit E, its flow is gradual because it passes through the throttle valve 34 with a check valve, so that the valve body 30 also slowly moves to open. In this way, at the start of refueling, the flow control valve 17 gradually opens and does not open suddenly, which has the advantage of preventing damage to the meter 3 and other fueling equipment.

【００２６】 このようにして給油が開始され、開となった流量制御弁１７を介し、所定の給 油圧力のもとに給油配管Ｄ中を燃料油が流れて行く。そして給油が進行し、図示 実施例では、正式の給油プリセット量より若干少ない予備の給油プリセット量に 給油積算量が達すると、次のようになる。すなわちコントローラ２７により、制 御回路Ｅの第１電磁弁２４および第２電磁弁２５が閉に切り換わると共に、第３ 電磁弁３６が開に切り換わり、流量制御弁１７の入口側２１から分岐流入した一 部の燃料油が、第３電磁弁３６から補助回路Ｆを介し弁体３０の後側に流入して 、弁体３０を所定量だけ移動させると、リミットスイッチ３３がこれを検出し、 コントローラ２７にて第３電磁弁３６が一旦閉じられる。そこで、流量制御弁１ ７は予め設定した所定開度を維持し、給油配管Ｄ中を流れる燃料油の給油流速は 低速となる。しかる後、正式の給油プリッセットに給油積算量が達すると、コン トローラ２７により第３電磁弁３６が再度開とされ、補助回路Ｆを介した燃料油 にて弁体３０が閉に移動され、流量制御弁１７は閉となり、もって給油配管Ｄ中 の燃料油の流れが遮断されて、給油は終了する。In this way, refueling is started, and the fuel oil flows through the refueling pipe D under the predetermined refueling pressure via the flow rate control valve 17 which is opened. When the refueling progresses and the cumulative amount of refueling reaches the reserve refueling preset amount which is slightly smaller than the official refueling preset amount in the illustrated embodiment, the following occurs. That is, the controller 27 switches the first solenoid valve 24 and the second solenoid valve 25 of the control circuit E to be closed, and the third solenoid valve 36 to be opened, so that the branch inflow from the inlet side 21 of the flow control valve 17 is performed. When a part of the fuel oil flows into the rear side of the valve body 30 from the third electromagnetic valve 36 through the auxiliary circuit F and moves the valve body 30 by a predetermined amount, the limit switch 33 detects this and The third electromagnetic valve 36 is once closed by the controller 27. Therefore, the flow rate control valve 17 maintains a preset predetermined opening degree, and the refueling flow velocity of the fuel oil flowing in the refueling pipe D becomes low. Thereafter, when the cumulative amount of refueling reaches the official refueling preset, the controller 27 causes the third solenoid valve 36 to be reopened, and the valve body 30 is moved to the closed position by the fuel oil passing through the auxiliary circuit F. The flow control valve 17 is closed, the flow of fuel oil in the oil supply pipe D is interrupted, and the oil supply is completed.

【００２７】 ところで、このような給油中に、給油圧力が変化するようなことがあると、次 のようになる。例えば給油が進行すると、航空機側の各タンク室は、一定量の給 油が完了したものから順次その元弁が閉鎖されて行くが、開放されている元弁の 数が少なくなると、サービサの給油配管Ｄ側から給油される燃料油の取り込み・ 吸収が困難化し、給油圧力が上昇する。そして、航空機側の集合配管等の許容圧 力は、例えば５０psi 以下と低いので、給油圧力がこれに見合った所定値以上に 上昇した場合には、給油配管Ｄのベンチュリ５における圧力変化に基づき、制御 回路Ｅの圧力制御弁２６は絞られ絞り度が調整される。すると、その絞られた分 だけ制御回路Ｅ中に分岐流入した燃料油が、補助回路Ｆを介し弁体３０の後側に 流入して、弁体３０を開から閉側に所定量だけ移動させ、もって給油配管Ｄの流 量制御弁１７の開閉度が、より閉に調整され予め設定した圧力となる。このよう にして、給油配管Ｄ中を流れる燃料油が絞られ、上昇していた給油圧力が所定値 まで下げられ、一定の給油圧力に調整される。By the way, if the refueling pressure may change during such refueling, the following will occur. For example, as refueling progresses, the tank valves on the aircraft side will gradually close their main valves from the time when a certain amount of refueling has been completed, but if the number of open main valves decreases, the servicer's refueling will decrease. It becomes difficult to take in and absorb the fuel oil supplied from the pipe D side, and the oil supply pressure rises. Since the allowable pressure of the collecting pipe on the aircraft side is low, for example, 50 psi or less, when the refueling pressure rises above a predetermined value corresponding to this, based on the pressure change in the venturi 5 of the refueling pipe D, The pressure control valve 26 of the control circuit E is throttled and the degree of throttling is adjusted. Then, the fuel oil branched and flown into the control circuit E by the throttled amount flows into the rear side of the valve body 30 through the auxiliary circuit F and moves the valve body 30 from the open side to the closed side by a predetermined amount. Therefore, the opening / closing degree of the flow rate control valve 17 of the oil supply pipe D is adjusted to be more closed and becomes a preset pressure. In this way, the fuel oil flowing through the oil supply pipe D is throttled, the increased oil supply pressure is reduced to a predetermined value, and the oil supply pressure is adjusted to a constant value.

【００２８】 更に、給油中に給油圧力が急激に変化し、サージ圧力が発生するようなことが あると、次のようになる。例えば、給油中に何らかの理由により、航空機側の各 タンク室の元弁を同時にすべて閉とするようなことがあると、給油配管Ｄ中の燃 料油の給油圧力が急激に上昇して、サージ圧力が発生するが、この場合には、ベ ンチュリ５における急激な圧力変化に基づき、制御回路Ｅと補助回路Ｆ間のサー ジ圧力制御弁３５が開に切り換えられる。すると、制御回路Ｅに分岐流入した燃 料油は、直ちに、開のサージ圧力制御弁３５から補助回路Ｆを介し弁体３０の後 側に流入して、弁体３０を閉に移動させる。このようにして、直ちに、流量制御 弁１７が閉となり、給油配管Ｄ中の燃料油の流れが遮断される。Further, if the refueling pressure suddenly changes during refueling and a surge pressure is generated, the following occurs. For example, if for some reason the main valves of each tank room on the aircraft side are all closed at the same time during refueling, the refueling pressure of the fuel oil in refueling pipe D rises sharply, causing a surge. Pressure is generated, but in this case, the surge pressure control valve 35 between the control circuit E and the auxiliary circuit F is switched to open based on the rapid pressure change in the venturi 5. Then, the fuel oil branched into the control circuit E immediately flows from the open surge pressure control valve 35 to the rear side of the valve body 30 via the auxiliary circuit F, and moves the valve body 30 to the closed state. In this way, the flow control valve 17 is immediately closed and the flow of fuel oil in the oil supply pipe D is shut off.

【００２９】 さて、サービサではこのような給油制御装置２０により、給油される燃料油の 給油量の制御と給油圧力の調整とが、１つの給油機器である流量制御弁１７にて 行われ、給油配管Ｄの１箇所で一体的に実施される。つまり、この種従来例のよ うに、給油量と給油圧力とが別々の独立した給油機器により、制御，調整される のではなく、流量制御弁１７に所定の制御回路Ｅ等を付設するだけで、これらを 一体的に実施できるようになる。In the servicer, the refueling control device 20 controls the refueling amount of the fuel oil to be refueled and adjusts the refueling pressure by the flow control valve 17, which is one refueling device. It is integrally performed at one place of the pipe D. That is, unlike the conventional example of this kind, the oil supply amount and the oil supply pressure are not controlled and adjusted by separate independent oil supply devices, but only by attaching a predetermined control circuit E or the like to the flow control valve 17. , It will be possible to implement these integrally.

【００３０】 なお、図示実施例では燃料給油車の１例としてサービサが示されているが、本 考案はこれに限定されるものではなく、サービサとは異なりタンクを搭載し、こ のタンクに積載された燃料油を、車載のポンプにて給油配管Ｄに供給して給油を 行うタイプの燃料給油車にも、勿論適用可能である。In the illustrated embodiment, the servicer is shown as an example of the fuel refueling vehicle, but the present invention is not limited to this, and unlike the servicer, a tank is installed and the servicer is loaded on the tank. Of course, it is also applicable to a fuel refueling vehicle of the type that refuels by supplying the refueled fuel oil to the refueling pipe D by an on-vehicle pump.

【００３２】 すなわち、給油される燃料油の給油量の制御と給油圧力の調整とは、１つの給 油機器である流量制御弁により、給油配管の１箇所で実施される。従って、給油 量の制御と給油圧力の調整とを別々に独立して行う場合に比し、給油機器類全体 が小型化されると共に、その取付工数も削減され、調整等も簡略化されて精度が 向上し、コスト面にも優れるようになる。このように、この種従来例に存した問 題点が一掃される等、本考案の発揮する効果は、顕著にして大なるものがある。That is, the control of the amount of fuel oil to be refueled and the adjustment of the refueling pressure are carried out at one location on the refueling pipe by the flow control valve, which is one refueling device. Therefore, compared to the case where the control of the refueling amount and the adjustment of the refueling pressure are carried out separately and independently, the entire refueling equipment is downsized, the number of man-hours for mounting the refueling equipment is reduced, the adjustment is simplified, and the accuracy is improved. Will be improved and the cost will be improved. Thus, the effects of the present invention are remarkably great, such as the problems existing in this type of conventional example are eliminated.
