る。(D) Function In this invention, when inspecting whether or not there is damage to the suction pipe leading from the meter to the underground tank at a gas station, the meter is operated,
The oil is sucked up by the underground tank through the suction pipe, and then sent from the oil drain hose of the weighing machine through the oil supply port into the main body of the container of the present invention, and when the container is full, the oil is discharged from the oil drain port. It flows out toward the oil supply nozzle, and in this case, the oil supply pipe is arranged as low as possible with respect to the bottom of the container main body of the present invention, and the oil drain port is arranged in the upper position as possible. As a result, the container body will be full of oil shortly after oil is pumped, and if air is mixed in from the damaged part of the suction pipe, the air will float to the top of the container body and accumulate, causing the oil drain port to become full. As more oil is pushed out, it can be clearly seen from the outside whether air is flowing in or not, and if water is mixed in the oil, the water will settle to the bottom of the container body. This is another visual confirmation of water contamination. Furthermore, in order to assemble the leakage testing device, the lower part of the cylindrical container body is fitted into the groove on the upper surface of the lower presser frame, the upper end of the container body is closed with the upper presser frame, and then the lower presser frame is closed. The upper presser frame is connected by the tightening bolt.

容器本体及び上押えフレームを取り外すことがで
きる。 Further, by loosening the tightening bolts, the container body and the upper presser frame can be easily removed.

る。(e) Effects According to this invention, it is possible to quickly visually confirm the inflow of air, water, etc. into the oil from the outside, and it is possible to confirm whether there is any damage or leakage accident in the middle of the suction pipe. The mixed air can be quickly discharged from the container body, which has the effect of making it easier to visually check the air mixed situation. Further, according to the present invention, by easily disassembling the leakage testing device, internal inspection of the leakage testing device and replacement of parts can be performed.
