Description

本発明は、地下タンクへの誤注油防止装置に関し、特に、タンクローリから給油所の地下タンクへ荷卸しする燃料油の誤注油を防止する装置に関する。 The present invention relates to a device for preventing erroneous lubrication to an underground tank, and more particularly to a device for preventing erroneous lubrication of fuel oil to be unloaded from a tank truck to an underground tank at a gas station.

給油所に燃料油を配送するタンクローリは、複数のハッチ毎にガソリン、軽油、灯油を積み込み、給油所の地下タンクヘ荷卸しするときには、タンクローリ側の１本の吐出管を共用する。そのため、油種を間違えて荷卸しする可能性を否定できない。このような事態が発生すると、荷卸しされた燃料油が無駄になるだけでなく、混油した燃料油を販売することもできない。さらに、混油後の燃料油の後始末も容易ではない。 The tank lorry that delivers fuel oil to the gas station loads gasoline, light oil, and kerosene for each of a plurality of hatches, and shares one discharge pipe on the tank lorry side when unloading to the underground tank of the gas station. Therefore, it cannot be denied that the oil type may be mistakenly unloaded. When such a situation occurs, not only the unloaded fuel oil is wasted, but also the mixed fuel oil cannot be sold. Furthermore, it is not easy to clean up the fuel oil after mixing.

そこで、本発明は、燃料油を給油所に荷卸しする際の地下タンクヘの誤注油を防止することを目的とする。 Therefore, an object of the present invention is to prevent erroneous lubrication to an underground tank when unloading fuel oil to a gas station.

上記目的を達成するため、本発明は、地下タンクへの誤注油防止装置であって、給油所の地下タンクから地上へ延設される注油管に設けられる弁と、該弁の内部を所定の種類の燃料油が通過すると、該弁の弁体を閉方向へ移動させる弁体駆動手段とを備えることを特徴とする。 In order to achieve the above object, the present invention is an erroneous lubrication prevention device for an underground tank, in which a valve provided in an lubrication pipe extending from the underground tank of a gas station to the ground and the inside of the valve are defined. It is characterized by comprising a valve body driving means for moving the valve body of the valve in the closing direction when the type of fuel oil passes through.

本発明によれば、燃料油を給油所に荷卸しする際に、弁の内部を所定の種類の燃料油（荷卸ししようとしている燃料油とは異なる種類の燃料油）が通過すると、弁体駆動手段が弁体を閉方向へ回転させて地下タンクへ流れるのを妨げるため、地下タンクへの誤注油を防止することができる。 According to the present invention, when unloading fuel oil to a refueling station, when a predetermined type of fuel oil (a type of fuel oil different from the fuel oil to be unloaded) passes through the inside of the valve, the valve body Since the driving means prevents the valve body from rotating in the closing direction and flowing to the underground tank, it is possible to prevent erroneous lubrication to the underground tank.

上記地下タンクへの誤注油防止装置において、前記弁体駆動手段の一部が溶けることにより、該弁体駆動手段による前記弁体の保持が解かれ、前記弁体が閉方向へ回転するように構成することができる。これにより、簡単な構成で、燃料油を給油所に荷卸しする際の地下タンクヘの誤注油を防止することができる。 In the device for preventing erroneous lubrication to the underground tank, when a part of the valve body driving means is melted, the holding of the valve body by the valve body driving means is released so that the valve body rotates in the closing direction. Can be configured. As a result, it is possible to prevent erroneous lubrication to the underground tank when unloading fuel oil to a gas station with a simple configuration.

前記弁体は、円板状に形成され、円筒状の弁本体に収容され、該弁体と一体の弁軸を介して回転し、前記弁本体の軸線方向に対して平行となった場合に該弁を開き、前記弁本体の軸線方向に対して垂直となった場合に該弁を閉じるように構成することができる。 When the valve body is formed in a disk shape, is housed in a cylindrical valve body, rotates via a valve shaft integrated with the valve body, and becomes parallel to the axial direction of the valve body. The valve can be configured to open and close when it is perpendicular to the axial direction of the valve body.

例えば、前記弁体駆動手段は、前記弁体の一方の面に固定され、該弁体を閉方向へ付勢する錘と、一端が前記弁本体の内面に固定され、他端が前記弁体を開位置で保持する張設部材をと備え、該張設部材が溶けることにより、前記弁体の保持が解かれるように構成することができる。 For example, the valve body driving means is fixed to one surface of the valve body, has a weight for urging the valve body in the closing direction, one end is fixed to the inner surface of the valve body, and the other end is the valve body. It is possible to provide an upholstery member for holding the valve body in an open position, and to release the holding of the valve body by melting the upholstery member.

また、前記弁体駆動手段は、前記弁体の一方の面に固定され、該弁体を閉方向へ付勢する錘と、一端が前記弁本体に挿入され、他端が前記弁体を開位置で保持するピン状部材とを備え、該ピン状部材が溶けることにより、前記弁体の保持が解かれるように構成することもできる。 Further, the valve body driving means is fixed to one surface of the valve body, has a weight for urging the valve body in the closing direction, one end is inserted into the valve body, and the other end opens the valve body. It is also possible to provide a pin-shaped member to be held at the position, and to release the holding of the valve body by melting the pin-shaped member.

さらに、前記弁体駆動手段は、前記弁体の一方の面に固定され、該弁体を閉方向へ付勢する錘及び第１の翼状部材と、前記弁体の他方の面に固定される第２の翼状部材とを備え、前記第１の翼状部材が溶けることにより、該弁体駆動手段による前記弁体の保持が解かれるように構成することもできる。 Further, the valve body driving means is fixed to one surface of the valve body, and is fixed to a weight and a first wing-shaped member for urging the valve body in the closing direction, and to the other surface of the valve body. A second wing-shaped member may be provided, and the valve body may be released from being held by the valve body driving means by melting the first wing-shaped member.

以上のように、本発明によれば、燃料油を給油所に荷卸しする際の地下タンクヘの誤注油を防止することができる。 As described above, according to the present invention, it is possible to prevent erroneous lubrication to the underground tank when unloading fuel oil to a gas station.

次に、本発明を実施するための形態について、図面を参照しながら詳細に説明する。 Next, a mode for carrying out the present invention will be described in detail with reference to the drawings.

図１及び図２は、本発明に係る地下タンクへの誤注油防止装置（以下「誤注油防止装置」という。）の第１の実施形態を示し、この誤注油防止装置１は、弁体回転式弁、いわゆるバタフライバルブを利用したものである。 1 and 2 show a first embodiment of an erroneous lubrication prevention device (hereinafter referred to as “erroneous lubrication prevention device”) for an underground tank according to the present invention, and the erroneous lubrication prevention device 1 is a valve body rotation. It uses a type valve, a so-called butterfly valve.

誤注油防止装置１は、弁の構成部材として、円筒状の弁本体２と、弁本体２の内部に収容される円板状の弁体３と、弁体３と一体に形成される弁軸４と、弁本体２と弁体３との間に張設され、弁体３を弁開位置で保持する張設部材５と、弁体３を弁開位置で支持するストッパ６と、弁体３を弁閉位置で支持するストッパ７と、弁体の片面に設けられる錘８と、弁軸４の一端に取り付けられる開閉指針９と、弁本体２に設けられ、外部から弁体３の状態を確認するサイトグラス１０と、弁開位置にある弁軸４を弁閉方向に付勢する板ばね１４等で構成される。 The erroneous lubrication prevention device 1 includes a cylindrical valve body 2, a disk-shaped valve body 3 housed inside the valve body 2, and a valve shaft integrally formed with the valve body 3 as valve components. A tension member 5 stretched between the valve body 2 and the valve body 3 to hold the valve body 3 at the valve opening position, a stopper 6 for supporting the valve body 3 at the valve opening position, and a valve body. A stopper 7 for supporting 3 at the valve closed position, a weight 8 provided on one side of the valve body, an opening / closing guideline 9 attached to one end of the valve shaft 4, and a state of the valve body 3 provided on the valve body 2 from the outside. It is composed of a sight glass 10 for confirming the above, a leaf spring 14 for urging the valve shaft 4 at the valve opening position in the valve closing direction, and the like.

弁本体２の右側開口が地下タンクの注油管側に接続されると共に、左側開口がタンクローリの注油ホース側に接続される。 The right opening of the valve body 2 is connected to the lubrication pipe side of the underground tank, and the left opening is connected to the lubrication hose side of the tank truck.

弁軸４は、弁本体２に回転可能に保持され、弁軸４が回転することで弁体３も弁軸４の軸線回りに回転する。弁体３が回転して弁体３の外周面が弁本体２の内周面と当接することで弁が閉じる。また、２つの弁軸４の一端は、弁本体２を貫通して弁本体２の外表面から突出し、一方の弁軸４の先端には、図１（ｂ）に示す開閉指針９が取り付けられる。また、弁本体２の外表面から突出した一方又は両方の弁軸４の先端には板ばね１４の一端が固定され、板ばね１４の他端が弁本体２に固定されることで、板ばね１４は、弁開位置にある弁軸４を弁閉方向に付勢する。 The valve shaft 4 is rotatably held by the valve body 2, and the rotation of the valve shaft 4 causes the valve body 3 to rotate about the axis of the valve shaft 4. The valve closes when the valve body 3 rotates and the outer peripheral surface of the valve body 3 comes into contact with the inner peripheral surface of the valve body 2. Further, one end of the two valve shafts 4 penetrates the valve body 2 and protrudes from the outer surface of the valve body 2, and the opening / closing guideline 9 shown in FIG. 1B is attached to the tip of one valve shaft 4. .. Further, one end of the leaf spring 14 is fixed to the tip of one or both valve shafts 4 protruding from the outer surface of the valve body 2, and the other end of the leaf spring 14 is fixed to the valve body 2. 14 urges the valve shaft 4 at the valve opening position in the valve closing direction.

張設部材５は、棒状又は紐状で、ガソリンで溶ける材料で形成され、通常状態では弁体３を弁開位置で保持し、ガソリンが混入した場合に溶けて弁体３の保持を解除する。 The upholstery member 5 is rod-shaped or string-shaped and is made of a material that dissolves in gasoline. In a normal state, the valve body 3 is held at the valve open position, and when gasoline is mixed in, the tension member 5 melts and releases the holding of the valve body 3. ..

２つのストッパ６、７は、弁本体２の内周面から突出する板状に形成され、弁体３が弁開位置にあるときにストッパ６の下面が弁体３の表面に当接し、弁体３が弁閉位置にあるときにストッパ７の左面が弁体３の表面に当接する。 The two stoppers 6 and 7 are formed in a plate shape protruding from the inner peripheral surface of the valve body 2, and when the valve body 3 is in the valve open position, the lower surface of the stopper 6 comes into contact with the surface of the valve body 3 to form a valve. When the body 3 is in the valve closed position, the left surface of the stopper 7 comes into contact with the surface of the valve body 3.

次に、上記構成を有する誤注油防止装置１の動作について説明する。 Next, the operation of the erroneous lubrication prevention device 1 having the above configuration will be described.

通常状態では、図１（ａ）に示すように、弁体３は、張設部材５及びストッパ６によって開位置に保持され、弁は開いている。この状態で灯油が荷卸しされると、灯油は誤注油防止装置１を通過して地下タンクに流れる。図１（ｂ）に示すように開閉指針９は「開」を指し、サイトグラス１０からも開弁状態を確認することができる。 In the normal state, as shown in FIG. 1A, the valve body 3 is held in the open position by the tension member 5 and the stopper 6, and the valve is open. When kerosene is unloaded in this state, the kerosene passes through the erroneous lubrication prevention device 1 and flows into the underground tank. As shown in FIG. 1 (b), the opening / closing guideline 9 indicates “open”, and the valve opening state can also be confirmed from the sight glass 10.

誤って灯油にガソリンが混じった場合には、図２（ａ）に示すように、張設部材５が溶けて切れ、弁体３が錘８に加わる重力、及び板ばね１４の付勢力によって時計回りに回転する。そして、図２（ｂ）に示すように、弁体３がストッパ７に当接し、弁体３の外周面が弁本体２の内周面と当接することで弁が閉じられ、ガソリンが地下タンクに流入するのを防止する。図２（ｃ）に示すように開閉指針９は「閉」を指し、サイトグラス１０からも閉弁状態を確認することができる。また、弁が閉じたことを給油所の事務所等に設けた報知器から出力することで、混油が生じたことを即座に給油所の係員等に知らせることができる。 If gasoline is mistakenly mixed with kerosene, as shown in FIG. 2A, the tension member 5 melts and breaks, the gravity of the valve body 3 applied to the weight 8, and the urging force of the leaf spring 14 cause the watch. Rotate around. Then, as shown in FIG. 2B, the valve body 3 comes into contact with the stopper 7, and the outer peripheral surface of the valve body 3 comes into contact with the inner peripheral surface of the valve body 2, so that the valve is closed and gasoline is discharged into the underground tank. Prevent inflow to. As shown in FIG. 2C, the opening / closing pointer 9 indicates “closed”, and the valve closed state can be confirmed from the sight glass 10. Further, by outputting the closing of the valve from a notification device provided in the office of the gas station or the like, it is possible to immediately notify the staff of the gas station or the like that the mixed oil has occurred.

尚、混油が生じて張設部材５が溶けた後、張設部材５を新たなものに交換することで、誤注油防止装置１を元の状態に復帰させることができる。 After the mixed oil is generated and the tensioning member 5 is melted, the erroneous lubrication prevention device 1 can be returned to the original state by replacing the tensioning member 5 with a new one.

次に、本発明に係る誤注油防止装置の第２の実施の形態について、図３を参照しながら説明する。 Next, a second embodiment of the erroneous lubrication prevention device according to the present invention will be described with reference to FIG.

この誤注油防止装置１１は、上記誤注油防止装置１の張設部材５の代わりに、弁体３の一端に設けられるピン状部材１２と、図３（ａ）に示すように、弁体３の弁開位置でピン状部材１２が挿入されて保持される軸受１３を備え、ピン状部材１２をガソリンで溶ける材料で形成した。その他の構成要素は、上記誤注油防止装置１と同じである。 The erroneous lubrication prevention device 11 includes a pin-shaped member 12 provided at one end of the valve body 3 instead of the tension member 5 of the erroneous lubrication prevention device 1, and the valve body 3 as shown in FIG. 3A. A bearing 13 in which the pin-shaped member 12 is inserted and held at the valve opening position of the above is provided, and the pin-shaped member 12 is made of a material that is soluble in gasoline. Other components are the same as the above-mentioned erroneous lubrication prevention device 1.

上記構成により、通常状態では、図３（ａ）に示すように、弁体３は、ピン状部材１２及びストッパ６によって開位置に保持され、弁は開いている。この状態で灯油が荷卸しされると、灯油は誤注油防止装置１１を通過して地下タンクに流れる。 With the above configuration, in the normal state, as shown in FIG. 3A, the valve body 3 is held in the open position by the pin-shaped member 12 and the stopper 6, and the valve is open. When kerosene is unloaded in this state, the kerosene passes through the erroneous lubrication prevention device 11 and flows into the underground tank.

誤って灯油にガソリンが混じった場合には、図３（ｂ）に示すように、ピン状部材１２が溶けて弁体３の保持状態を解除することで、弁体３が錘８に加わる重力、及び板ばね１４の付勢力によって時計回りに回転する。そして、図２（ｂ）の状態を経て、弁体３がストッパ７に当接し、弁体３の外周面が弁本体２の内周面と当接することで弁が閉じられ、ガソリンが地下タンクに流入するのを防止する。 When gasoline is mistakenly mixed with kerosene, as shown in FIG. 3B, the pin-shaped member 12 melts and the holding state of the valve body 3 is released, so that the valve body 3 is applied to the weight 8 by gravity. , And the urging force of the leaf spring 14 rotates clockwise. Then, through the state of FIG. 2B, the valve body 3 comes into contact with the stopper 7, and the outer peripheral surface of the valve body 3 comes into contact with the inner peripheral surface of the valve body 2, so that the valve is closed and gasoline is discharged into the underground tank. Prevent inflow to.

次に、本発明に係る誤注油防止装置の第３の実施の形態について、図４及び図５を参照しながら説明する。 Next, a third embodiment of the erroneous lubrication prevention device according to the present invention will be described with reference to FIGS. 4 and 5.

この誤注油防止装置２１は、図４（ａ）〜（ｃ）に示すように、上記誤注油防止装置１の張設部材５に代えて、弁体３の表裏面に翼状部材２２、２４を設け、錘８に代えて、裏面上に２つの錘２３を備え、裏面上の翼状部材２４をガソリンで溶ける材料で形成した。その他の構成要素は、上記誤注油防止装置１と同じである。 As shown in FIGS. 4A to 4C, the erroneous lubrication prevention device 21 has wing-shaped members 22 and 24 on the front and back surfaces of the valve body 3 instead of the tension member 5 of the erroneous lubrication prevention device 1. Instead of the weight 8, two weights 23 were provided on the back surface, and the wing-shaped member 24 on the back surface was formed of a material soluble in gasoline. Other components are the same as the above-mentioned erroneous lubrication prevention device 1.

上記構成により、通常状態の灯油が荷卸しされると、図４に示すように、灯油が流れることで２つの翼状部材２２、２４によって生じる揚力が略々同一であり、弁体３は、２つの錘２３の重力と、とストッパ６によって開位置に保持され、弁は開いている。そのため、灯油は誤注油防止装置２１を通過して地下タンクに流れる。 With the above configuration, when kerosene in a normal state is unloaded, as shown in FIG. 4, the lift generated by the two wing-shaped members 22 and 24 due to the flow of kerosene is substantially the same, and the valve body 3 has 2 It is held in the open position by the gravity of the weight 23 and the stopper 6, and the valve is open. Therefore, kerosene passes through the erroneous lubrication prevention device 21 and flows into the underground tank.

誤って灯油にガソリンが混じった場合には、図５（ａ）及び（ｂ）に示すように、翼状部材２４が溶け、上面の翼状部材２２による揚力のみが弁体３に加わり、この揚力が錘２３の重力より大きく、板ばね１４の付勢力も加わり、弁体３は時計回りに回転する。そして、図５の状態を経て、弁体３がストッパ７に当接し、弁体３の外周面が弁本体２の内周面と当接することで弁が閉じられ、ガソリンが地下タンクに流入するのを防止する。 When gasoline is mistakenly mixed with kerosene, as shown in FIGS. 5A and 5B, the wing-shaped member 24 melts, and only the lift from the wing-shaped member 22 on the upper surface is applied to the valve body 3, and this lift is applied. It is larger than the gravity of the weight 23, and the urging force of the leaf spring 14 is also applied, so that the valve body 3 rotates clockwise. Then, through the state of FIG. 5, the valve body 3 comes into contact with the stopper 7, and the outer peripheral surface of the valve body 3 comes into contact with the inner peripheral surface of the valve body 2, so that the valve is closed and gasoline flows into the underground tank. To prevent.

尚、上記実施の形態においては、バタフライバルブを利用したが、その他の種類の弁構造としてもよく、弁体駆動手段としての張設部材５等をガソリンで溶ける材料で形成したが、その他の構成を有する弁体駆動手段を用い、弁体駆動手段の構成要素の一部をガソリンで溶ける材料で形成してもよい。 In the above embodiment, the butterfly valve is used, but other types of valve structures may be used, and the tension member 5 or the like as the valve body driving means is formed of a material that can be dissolved in gasoline, but other configurations are used. The valve body driving means may be used, and a part of the components of the valve body driving means may be formed of a material that is soluble in gasoline.

また、上記実施の形態においては灯油を給油している場合に誤ってガソリンが混入した場合を例示したが、ガソリン以外の燃料油にのみ溶ける材料を用いて、ガソリン以外の燃料油の混油を防止することもできる。 Further, in the above embodiment, the case where gasoline is mistakenly mixed in when kerosene is being refueled has been illustrated, but a mixed oil of fuel oil other than gasoline is used by using a material that is soluble only in fuel oil other than gasoline. It can also be prevented.
