Description

Technical Field

[0001] The utility model relates to the technical field of storage tank leakage testing, in particular to a leakage testing device for petroleum storage tank accessories. Background Art

[0002] Oil storage tanks are equipment used to store crude oil, refined oil or other petroleum products. They are very important facilities in the oil industry. However, oil storage tanks may leak during use, which will not only cause economic losses, but also have serious impacts on the environment and human health. The leakage problem of oil storage tanks mainly includes two aspects: one is the leakage caused by the equipment itself, such as equipment aging, equipment damage, etc.; the other is the leakage caused by operating errors or external factors, such as man-made damage, natural disasters, etc. Regardless of the cause of the leakage, timely measures need to be taken to avoid further expansion of the scope of the leakage and reduce losses. In order to timely detect and deal with the leakage problem of oil storage tanks, an oil storage tank accessory leakage test device has been developed. This device plays an important role in the problem of oil storage tank leakage.

[0003] During the use of the test device, since testing is required when there is leakage or discharge at the accessories of the oil storage tank, a sensor is needed to accurately detect the leakage amount. Otherwise, it is impossible to accurately know how much oil is stored in the tank. The oil also needs to be discharged in multiple ways, otherwise the speed of discharging the oil will directly affect the work efficiency. Utility Model Content

[0004] The disclosed embodiment relates to a leakage test device for oil storage tank accessories. In the process of discharging oil from the oil storage tank accessories, the oil will be discharged from the oil pipeline into the receiving tube. At this time, the oil will flow on the flow sensor. The leaked oil is tested by the flow sensor, and the leakage amount is accurately detected by the sensor, thereby avoiding the tedious process of manual detection. The test using the flow sensor has high accuracy, which can reduce the influence of human factors on the test results and reduce the error rate. In this way, the amount of oil left in the tank can be accurately calculated, and it is convenient to discharge it into containers of different sizes according to the amount of oil. The oil discharged from the oil storage tank accessories is discharged using a discharge pipe or an emergency discharge pipe as needed.
