Description

Technical Field

[0001] The utility model relates to the technical field of metering tanks, in particular to a metering tank for calibrating fuel dispensers. Background Art

[0002] As a professional metering device, the metering tank for calibrating fuel dispensers is mainly used for calibrating fuel dispensers at gas stations. It has accurate volume scales, can provide an accurate oil measurement environment for fuel dispensers, and ensure that the metering accuracy of fuel dispensers during refueling meets national standards. This device is usually designed with a stable support structure, easy-to-operate interfaces, and necessary sealing measures to ensure the smooth progress of calibration work. The metering tank for calibrating fuel dispensers is a key tool for regular calibration of fuel dispensers at gas stations. By comparing the amount of oil output by the fuel dispenser with the actual measured amount of oil in the metering tank, the metering error of the fuel dispenser can be accurately evaluated, ensuring that the metering accuracy of the fuel dispenser meets relevant standards and regulations. This is of great significance for protecting the rights and interests of consumers and ensuring the operation order of gas stations.

[0003] In the existing design of the metering tank for calibrating fuel dispensers, in order to facilitate the rapid injection of oil, a funnel is usually installed at the top of the tank body. However, the core problem of this design lies in the connection method between the funnel and the tank body - a sliding connection. Although this connection method is convenient for installation and disassembly, it has significant drawbacks in actual operation. When the oil is injected into the tank body through the funnel at a relatively fast speed, due to the pressure of the oil itself and the impact force generated during injection, it is very easy to form leakage at the connection between the funnel and the tank body. Once the oil overflows, it will not only cause waste of oil products, but more importantly, it will directly affect the accuracy and reliability of fuel dispenser calibration. In addition, the overflow of oil may also cause environmental pollution, increasing the difficulty and cost of cleaning work. Therefore, a metering tank for calibrating fuel dispensers is needed to solve the above problems. Summary of the Utility Model

Subsequently, screw the top cover 9 onto the top of the funnel 6, and insert the barrel of the fuel nozzle through the through hole 10 into the limit ring 13. At this time, the gap between the barrel of the fuel nozzle and the limit ring 13 is small, which can prevent the backflow of the oil fluid. Moreover, the setting of the exhaust pipe 23 facilitates the discharge of the air inside the metering tank body 3, preventing the increase of the internal air pressure of the metering tank body 3, and can ensure the accuracy of the fuel dispenser calibration metering.
