Description

本発明は、屋内に設置される燃料等の液体が装填されたタンク等における液面センサの取付け方法及び装置に関する。   The present invention relates to a method and an apparatus for mounting a liquid level sensor in a tank or the like loaded with a liquid such as fuel installed indoors.

屋内に設置される従来の燃料小出槽や、冷却水槽等のタンクにあっては、図２に示すように、床面１００に設置された架台１０１上に載置されたタンク１０２内に注入された液体の液面を検出するためにタンク１０２の上面１０２Ａからフロートスイッチや電極棒等の部品を含む液面センサを内蔵したフランジ部１０３を有する筒体１０４をタンク１０２の内部に挿入し、フランジ部１０３で固定するように構成されている。   As shown in FIG. 2, in the case of a conventional fuel dispensing tank installed indoors, a tank such as a cooling water tank, etc., it is injected into a tank 102 mounted on a gantry 101 installed on a floor surface 100. In order to detect the liquid level of the liquid, a cylinder 104 having a flange portion 103 containing a liquid level sensor including components such as a float switch and an electrode rod is inserted into the tank 102 from the upper surface 102A of the tank 102. It is comprised so that it may fix with the flange part 103. FIG.

しかしながら、上記従来の液面センサを備えたタンクにあっては、タンクを架台の上に取り付け、屋内に据え付けると、液面センサの故障時等に、屋内の天井と、タンク上部との間隙が少ないため、液面センサを内蔵する筒体をタンクから簡単に取り出すことができないという問題がある。   However, in a tank equipped with the above-described conventional liquid level sensor, if the tank is mounted on a base and installed indoors, the gap between the indoor ceiling and the upper part of the tank will be lost when the liquid level sensor fails. Since there are few, there exists a problem that the cylinder which incorporates a liquid level sensor cannot be easily taken out from a tank.

従来の液面センサを備えたタンクを屋内に設置した状態を図３に示す。同図において、屋内１１０の床１１１上には防油堤１１２が形成されている。防油堤１１２上には架台１１３が設置されており、架台１１３上には、液面センサ１１４を備えたタンク１１５が載置されている。液面センサは筒体１１４に内臓されており、この筒体１１は、タンク１１５の上部より挿入され、フランジ部１１５をタンク１１５にボルト締めすることにより固定されている。   The state which installed the tank provided with the conventional liquid level sensor indoors is shown in FIG. In the figure, an oil breakwater 112 is formed on a floor 111 of an indoor 110.

この状態で液面センサ１１４の故障等により液面センサ１１４が内蔵された筒体１１４をタンク１１５から取り出し、交換しようとすると、タンク１１５条面と屋内１１０の天井１２０との間の隙間がないため、すなわち、筒体１１４の長さをＸ、タンク１１５の上面から天井までの距離をＹとすると、Ｘ＞Ｙであるため、タンク１１５上面から筒体１１４を簡単に取り出すことができないという問題がある。すなわち、タンク１１５から液面センサが内蔵された筒体１１４を取り出すには、タンク１１５を架台上で傾けるか、タンク１１５を床１１１上に一旦、降ろす必要があり、液面センサの交換が大掛かりな工事となり、コスト高となるという問題が有った。   In this state, there is no gap between the tank 115 and the ceiling 120 of the indoor 110 when the cylinder 114 containing the liquid level sensor 114 is taken out of the tank 115 due to failure of the liquid level sensor 114 or the like. Therefore, if the length of the cylinder 114 is X and the distance from the top surface of the tank 115 to the ceiling is Y, then X> Y, so that the cylinder 114 cannot be easily removed from the top surface of the tank 115. There is. That is, in order to take out the cylindrical body 114 containing the liquid level sensor from the tank 115, it is necessary to incline the tank 115 on the gantry or lower the tank 115 once on the floor 111, which requires a large replacement of the liquid level sensor. The construction was expensive and the cost was high.

すなわち、本実施形態では、例えば、フロート５０１により上限の液面レベルを検出し、フロート５０４により下限の液面レベルを検出するように各、フロートの液面変位に伴う上下方向の移動範囲が設定されている。 Further, when the float 504 moves to a position where it comes into contact with the lower stopper 506, a reed switch (not shown) provided in the tube body 500 is turned on, and comes into contact with the upper stopper 502. The reed switch is set to be in an OFF state when it is raised to the position.
That is, in this embodiment, for example, the range of movement in the vertical direction associated with the liquid level displacement of the float is set so that the upper limit liquid level is detected by the float 501 and the lower limit liquid level is detected by the float 504. Has been.

このように、フロート５０１、５０４、リードスイッチ等を構成要素とする液面センサ内蔵する筒体５０には、バルブ２１を閉じ、バルブ２０を開くことにより。タンク１５と筒体５０とが配管１７、Ｔ字状配管１８、配管１９、５１を介して連通し、タンク１５内の燃料等の液体４０が筒体５０に流れ込み、筒体５０内の液面レベルは、タンク内と同じ液面レベルになる。   In this way, by closing the valve 21 and opening the valve 20 in the cylinder 50 containing the liquid level sensor including the floats 501 and 504, the reed switch, and the like as components. The tank 15 and the cylinder 50 communicate with each other through the pipe 17, the T-shaped pipe 18, and the pipes 19 and 51, and the liquid 40 such as fuel in the tank 15 flows into the cylinder 50, and the liquid level in the cylinder 50 The level is the same as that in the tank.

このようにして、タンク１５内の液体４０を使用可能な状態にした後に、例えば、液面センサの故障等により液面センサを交換する必要が生じた場合には、バルブ２０を閉じ、バルブ２１を開いて筒体５０内の液体を排出させ、その後にフランジ３０、３１を固定していたボルトを外すことにより、液面センサを内蔵する筒体５０を水平方向に移動させて液面センサを内蔵する筒体５０を外す。外した筒体内の液面センサを修理するか、新品と交換した後に、再度、配管１９の端部に設けられたフランジ部３０と筒体５０の配管５１の端部に設けられたフランジ部３１とをボルト締めすることにより固定してタンク３０に筒体５０を取り付ける。   Thus, after the liquid 40 in the tank 15 is made usable, for example, when the liquid level sensor needs to be replaced due to a failure of the liquid level sensor, the valve 20 is closed and the valve 21 is closed. Is opened, the liquid in the cylinder 50 is discharged, and then the bolts fixing the flanges 30 and 31 are removed, thereby moving the cylinder 50 containing the liquid level sensor in the horizontal direction and moving the liquid level sensor. The built-in cylinder 50 is removed. After the removed liquid level sensor in the cylinder is repaired or replaced with a new one, the flange 30 provided at the end of the pipe 19 and the flange 31 provided at the end of the pipe 51 of the cylinder 50 again. Are fixed by bolting, and the cylinder 50 is attached to the tank 30.
