Description

Technical Field

[0001] This utility model relates to the field of metering tank technology, and in particular to a fuel dispenser calibration metering tank. Background Technology

[0002] A fuel dispenser calibration metering tank is a specialized device used to calibrate and test the flow rate and accuracy of fuel dispensers. It simulates the refueling process to ensure that the fuel dispenser can provide accurate fuel quantities in actual use.

[0003] However, during refueling, when the tank is full or the fuel level reaches the preset value, the fuel nozzle will automatically shut off. At this time, the nozzle head will close, cutting off the fuel flow. Because the nozzle is closed, some fuel will remain in the pipe. This fuel is left in the pipe due to the inertia of the fuel flow and the pressure inside the pipe during refueling. During the next refueling, this fuel remaining in the pipe will be added to the customer's tank. Due to the amount of fuel remaining in the pipe, especially in the case of frequent refueling, the amount of fuel added each time may be different. This inconsistency may affect the accuracy of the fuel dispensing.

[0004] Therefore, this utility model provides a fuel dispenser calibration metering tank. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fuel dispenser calibration metering tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fuel dispenser calibration metering tank, including a fuel dispensing component, wherein a squeezing component is fixedly connected inside the fuel dispensing component, and a pressurizing component is fixedly connected to the bottom end of the squeezing component;

[0007] The extrusion assembly includes a cylinder and an oil storage tank. The driving end of the cylinder is fixedly connected to a connecting rod, and the two ends of the connecting rod are respectively fixedly connected to push columns. The inside of the oil storage tank is slidably connected to a push plug, and the top end of the push plug is fixedly connected to a connecting column.

[0008] In a preferred embodiment, the pressurization assembly includes a support column, the top end of which is fixedly connected to the bottom end of a push column. A pressure spring is sleeved on the outside of the support column, and a telescopic column is slidably connected to the bottom end of the support column. A push plug is fixedly connected to the bottom end of the telescopic column.

[0009] The technical effect of adopting the above technical solution is that it further squeezes out the oil remaining in the pipeline after the refueling nozzle is turned off, thereby reducing the amount of oil remaining.

[0010] In a preferred embodiment, the refueling assembly includes a body, an internal refueling pipe fixedly connected to the body, one end of the refueling pipe fixedly connected to an oil storage tank, and the end of the refueling pipe away from the oil storage tank fixedly connected to a refueling nozzle.

[0011] The technical effect of adopting the above technical solution is to achieve fast and accurate oil delivery, while ensuring the metering accuracy during the refueling process.

[0012] In a preferred embodiment, the bottom of the oil storage tank is fixedly connected to the inside of the machine body.

[0013] The technical effect of adopting the above technical solution is to achieve a stable connection between the oil storage tank and the machine body, ensuring that the oil storage tank will not shift during the refueling process.

[0014] In a preferred embodiment, one end of the pressure spring is fixedly connected to the push column, and the other end of the pressure spring is fixedly connected to the telescopic column.

[0015] The technical effect of adopting the above technical solution is to achieve a constant pressure between the push column and the telescopic column, ensuring that after the fuel nozzle is closed, the push plug can continue to squeeze the oil in the pipeline, thereby further reducing the amount of oil residue.

[0016] In a preferred embodiment, the outer side of the telescopic column is slidably connected to the oil storage tank.

[0017] The technical effect of adopting the above technical solution is to ensure that the oil storage tank can be stably connected to the pusher plug 2 during sliding.

[0018] In a preferred embodiment, the outer side of the pusher plug is slidably connected to the oil storage tank.

[0019] The technical effects of adopting the above technical solution are: improved refueling efficiency and reduced oil residue in pipelines.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] This invention features a system where the operator activates the refueling nozzle, the control system commands the cylinder to operate, and the air pressure pushes the connecting rod and the push column, causing the push plug one inside the oil tank to move, squeezing oil into the refueling pipe. The pressure spring of the pressurizing component stores energy under the action of the telescopic column, causing the push plug two to slide inside the oil tank. The suction force of the push plugs increases the pressure, drawing oil from the pipe into the oil tank. The cylinder then presses downwards, repeatedly flushing out any remaining oil in the tank. This design achieves the benefits of accurate oil metering and continuous refueling, ensuring that oil can be accurately measured and continuously delivered to the refueling nozzle. Simultaneously, the pressurizing component effectively controls the pressure of the oil inside the oil tank, effectively reducing oil waste and minimizing the impact on the accuracy of the refueling volume.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1 and Figure 2As shown, this embodiment provides a technical solution: a fuel dispenser calibration metering tank, including a fuel dispensing component 1, the fuel dispensing component 1 including a body 11, a fuel dispensing pipe 12 fixedly connected inside the body 11, one end of the fuel dispensing pipe 12 fixedly connected to an oil storage tank 24, and a fuel dispensing nozzle 13 fixedly connected to the end of the fuel dispensing pipe 12 away from the oil storage tank 24.

[0032] The body 11 provides structural support for the entire refueling process. The body 11 may contain some internal mechanical and electronic components that control the refueling process. The refueling pipe 12 is responsible for transferring the fuel from the storage tank 24 to the refueling nozzle 13. The refueling nozzle 13 is the part that directly contacts the vehicle's fuel tank during the refueling process. The other end of the refueling pipe 12 is fixedly connected here. The refueling nozzle 13 usually contains a triggering mechanism that allows the operator to control the flow of the fuel.

[0033] like Figure 1 - Figure 4 As shown, the inside of the refueling component 1 is fixedly connected to the extrusion component 2. The extrusion component 2 includes a cylinder 21 and an oil storage tank 24. The bottom end of the oil storage tank 24 is fixedly connected to the inside of the machine body 11. The driving end of the cylinder 21 is fixedly connected to the connecting rod 22. The two ends of the connecting rod 22 are respectively fixedly connected to the push column 23. The inside of the oil storage tank 24 is slidably connected to the push plug 25. The top end of the push plug 25 is fixedly connected to the connecting column 26.

[0034] Cylinder 21 drives connecting rod 22 through gas pressure, thereby squeezing and pushing the oil. Oil tank 24 is a container for storing oil that needs to be refueled each time. Connecting rod 22 converts the linear motion of cylinder 21 into the linear motion of push column 23, thereby pushing the oil in oil tank 24. Push column 23 is directly connected to the top of push plug 25. Through the pushing force of connecting rod 22, push plug 25 moves inside oil tank 24, thereby pushing the oil. Push plug 25 is designed to push the oil to flow to refueling pipe 12. Connecting column 26 connects push plug 25 with the pushing force of connecting rod 22, ensuring that the pushing force can be effectively transmitted to push plug 25, thereby pushing the oil to flow.

[0035] The bottom end of the extrusion assembly 2 is fixedly connected to the pressure boosting assembly 3. The pressure boosting assembly 3 includes a support column 31. The top end of the support column 31 is fixedly connected to the bottom end of the push column 23. A pressure spring 32 is sleeved on the outside of the support column 31. A telescopic column 33 is slidably connected to the bottom end of the support column 31. One end of the pressure spring 32 is fixedly connected to the push column 23. The other end of the pressure spring 32 is fixedly connected to the telescopic column 33. The outside of the telescopic column 33 is slidably connected to the oil storage tank 24. A second push plug 34 is fixedly connected to the bottom end of the telescopic column 33. The outside of the second push plug 34 is slidably connected to the oil storage tank 24.

[0036] like Figure 3 and Figure 4As shown, the support column 31 serves to support and transmit force, connecting the push column 23 and the telescopic column 33. The pressure spring 32 is an elastic element used to provide a preset force in the system. Here, one end of the pressure spring 32 is fixed to the push column 23, and the other end is fixed to the telescopic column 33. When the telescopic column 33 extends or retracts, the pressure spring 32 can store and release energy, thereby increasing the pressure of the oil. The telescopic column 33 extends or retracts under the action of the pressure spring 32. The bottom end of the telescopic column 33 is slidably connected to the oil storage tank 24. Its extension and retraction can push the push plug 34, thereby affecting the pressure of the oil. The push plug 34 slides inside the oil storage tank 24. When the telescopic column 33 extends or retracts, the push plug 34 moves accordingly, thereby pushing the oil and increasing the pressure of the oil, ensuring that the oil can flow smoothly through the refueling pipe 12 to the refueling nozzle 13.

[0037] Working principle:

[0038] like Figure 1 - Figure 4 As shown:

[0039] In use: The operator first initiates the refueling process through the trigger mechanism of the refueling nozzle 13. At this time, the cylinder 21 starts working under the command of the control system, pushing the connecting rod 22 through gas pressure. The movement of the connecting rod 22 is converted into the linear movement of the pushing column 23, which in turn pushes the pushing plug 25 in the oil storage tank 24. The pushing plug 25 moves in the oil storage tank 24, squeezing the oil towards the refueling pipe 12. At the same time, the pressure spring 32 in the pressurizing component 3 stores energy under the extension and retraction of the telescopic column 33. The extension and retraction of the telescopic column 33 is driven by the elastic force of the pressure spring 32, pushing the pushing plug 34 to slide in the oil storage tank 24. Then, during the retraction of the squeezing component 2, the pushing plug 25 and the pushing plug 34 are drawn upwards, increasing the pressure. The oil in the pipe is sucked into the oil storage tank 24. Then the cylinder 21 is activated to squeeze downwards, so that the residual oil inside the oil storage tank 24 can be repeatedly flushed out.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
