Description

Technical Field

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

[0002] Fuel dispensers have developed along with the development of automobiles and road traffic. They are the sales terminals in the refined oil retail industry and are metering devices used for sales settlement.

[0003] The patent document with the publication number CN219495404U discloses a calibration metering tank for a fuel dispenser, which includes a thermal insulation shell. Inside the thermal insulation shell, there is a tank body. An oil inlet hole communicating with the outside is opened between the tank body and the thermal insulation shell. A sealing cover is arranged on the upper surface of the oil inlet hole. A bubble level is arranged on the upper surface of the thermal insulation shell. Discharge valves communicating with the tank body are respectively arranged on both sides of the lower surface of the thermal insulation shell. A base is arranged on the lower side of the thermal insulation shell. A cooling cavity is opened inside the base. A water pump is arranged inside the cooling cavity. A liquid delivery pipe extending into the thermal insulation shell is arranged outside the water pump. This calibration metering tank for a fuel dispenser can not only keep the oil level inside the metering tank horizontal, but also adjust the height of the metering tank, and at the same time can reduce the influence of external heat on the fuel inside the metering tank, further ensuring the accuracy of the fuel dispenser calibration result.

[0004] In the above application, although it can reduce the influence of external heat on the fuel inside the metering tank and further ensure the accuracy of the fuel dispenser calibration result, in the actual application process, the pressure inside the tank will be relatively large.
