The hydraulic section of the fuel dispenser is an important component inside the dispenser, containing flow meters, solenoid valves, etc., to realize functions such as fuel intake, pressurization, separation, measurement and control, ensuring the normal operation of the fuel dispenser.

[0003] Due to various factors such as gas station design, equipment layout, safety regulations, and operational needs, the location of the fuel outlet in the refueling islands at different gas stations is not exactly the same. Therefore, before installing the fuel dispenser on the refueling island, personnel need to be dispatched to the gas station site to conduct precise measurements. Based on the measurement data, the positions of the filter and fuel inlet pipe in the hydraulic zone are designed, and the fuel pipe between the filter and the flow meter also needs to be designed and adjusted. Then, suitable pipe fittings are customized based on the adjusted design. Finally, the pipe fittings, filter, fuel inlet pipe, flow meter, etc. are installed into the fuel dispenser. The whole process takes a long time, and many structures need to be adjusted during the installation.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-4 As shown, a hydraulic zone structure for a fuel dispenser includes: An adjustable oil inlet pipe and assembly fixedly installed with the fuel dispenser 1, wherein the adjustable oil inlet pipe includes: Connecting pipe 21, which is fixedly connected to the emergency shut-off valve of the gas station's refueling island; An adjusting pipe 22 is detachably connected to a connecting pipe 21. The adjusting pipe 22 includes two bends and a straight pipe, with one end of each bend fixedly connected to the straight pipe. An inlet pipe 23 is detachably connected to the end of the adjusting pipe 22 away from the connecting pipe 21, and the inlet pipe 23 is fixedly connected to the assembly component. The adjustable oil inlet pipe is configured as a three-section pipeline, with the connecting pipe 21 connecting to the refueling island of the gas station, and the inlet pipe 23 connecting to the assembly component. The adjusting pipe 22 is located in the middle between the connecting pipe 21 and the inlet pipe 23. By changing the angle of the adjusting pipe 22, a pipeline can be formed between the connecting pipe 21 and the inlet pipe 23, thereby connecting the assembly component to the refueling islands of different locations in the gas station, allowing the assembly component to be directly connected to the inlet pipe 23 as a whole. Therefore, the specifications of the adjusting pipe 22 only need to be determined in the early stage of the installation of the fuel dispenser 1, which requires less measurement data and customized pipe fittings, reducing the overall installation time. The assembly includes a plurality of solenoid valves 24, a plurality of filters 25 and a plurality of flow meters 26, wherein the number of solenoid valves 24 and flow meters 26 are equal; It should be noted that a single fuel dispenser 1 is generally equipped with four fuel nozzles on its surface, and the fuel dispenser 1 is generally equipped with two filters 25, four solenoid valves 24 and four flow meters 26 inside. Two solenoid valves 24 and two flow meters 26 are fixedly connected to the surface of a single filter 25. The solenoid valve 24 and filter 25 are fixedly installed, and the flow meter 26 is fixedly installed with both the solenoid valve 24 and filter 25. The inlet pipe 23 is fixedly connected to the flow meter 26. The solenoid valve 24, filter 25 and flow meter 26 are directly fixed as an integral component, and the positions of the three are relatively fixed. Therefore, before installation, only the optimal assembly position of the assembly component needs to be measured, and during installation, the individual position needs to be determined, which can be completed quickly. Two mounting plates are fixedly connected to the fuel dispenser 1. The flow meter 26 and the filter 25 are fixedly connected to the mounting plates respectively. The fuel dispenser 1 is equipped with fixed mounting plates, which limit the positions of the flow meter 26 and the filter 25. Therefore, the positions of the two mounting plates can be determined during installation to determine the positions of the assembly components, allowing for quick installation. In practical applications, the hydraulic section structure of this fuel dispenser is divided into an adjustable inlet pipe and an assembly component. The adjustable inlet pipe is a combination of a connecting pipe 21, an adjusting pipe 22, and an inlet pipe 23. The connecting pipe 21 connects to the fuel island of the gas station, and the inlet pipe 23 connects to the internal structure of the assembly component. The adjusting pipe 22 is a bend, allowing the assembly component to be adapted to fuel islands with different outlet pipes. The assembly component can be fixed in position by a mounting plate. Therefore, before installation, only the data of the adjusting pipe 22 and the installation position of the mounting plate need to be determined to complete the positions of the filter 25, solenoid valve 24, and flow meter 26 inside the hydraulic section of the fuel dispenser 1. During installation, the position of each individual structure in the assembly component can be determined to quickly install all structures, making the installation relatively simpler. This results in a shorter pre-installation measurement and preparation time, more convenient installation, and faster overall installation. In some specific implementations, a three-way flange 31 is fixedly connected between the solenoid valve 24 and the filter 25. An elbow flange 32 is fixedly connected to the end of the solenoid valve 24 away from the filter 25. A conduit 33 is fixedly connected to one end of the elbow flange 32. One end of the conduit 33 is fixedly connected to the flow meter 26. That is, the solenoid valve 24 is installed between the filter 25 and the flow meter 26, which reduces the impact of water hammer on the flow meter 26, improves the metering accuracy, and also increases the service life of the flow meter 26. In some specific implementations, the surface of the mounting plate is provided with a connecting groove 41, and a connecting rod 42 is fixedly connected inside the fuel dispenser 1. The surface of the connecting rod 42 is provided with several through grooves 43, and the connecting grooves 41 and the through grooves 43 are fixedly connected by bolts. Furthermore, the mounting plate and the fuel dispenser 1 are fixed in position by bolts, and the position of the mounting plate inside the fuel dispenser 1 can be adjusted by rotating and changing the position of the bolts. In a further embodiment, the mounting plate includes a flow meter mounting plate 51 and a filter mounting plate 52. The flow meter mounting plate 51 and the flow meter 26 are fixedly connected by bolts. The surface of the filter mounting plate 52 is provided with a plurality of adjustment grooves 53. An annular rod 54 is fixedly connected to the surface of the filter 25. The annular rod 54 is adapted to the adjustment grooves 53. The two ends of the annular rod 54 are threaded with retaining rings 55. In some specific implementations, the bent pipe and the straight pipe are fixed by a fixing assembly. The end of the bent pipe is fixed to the connecting rod 42 and the inlet pipe 23 by the fixing assembly. The fixing assembly includes a mounting ring 61 that is threaded to one end of the adjusting pipe 22. The mounting ring 61 and the adjusting pipe 22 are both provided with placement grooves. A washer 62 and a locking ring 63 are fixedly connected inside the placement groove. The surface of the locking ring 63 fits against the washer 62 and the placement groove. A sealing ring 64 is fixedly connected to the surface of the adjusting pipe 22 and contacts the adjusting pipe 22. A compression ring is fixedly provided inside the mounting ring 61 and contacts the mounting ring 61 and the locking ring 63. In a further embodiment, the cross-section of the bend is Z-shaped, and the diameter of the straight pipe is smaller than the diameter of the bend; the straight pipe can be directly inserted into the bend. In some specific implementations, a mounting block 71 is slidably connected to the surface of the regulating pipe 22, and a sealing gasket 72 is detachably connected between the mounting block 71 and the connecting pipe 21. The mounting block 71, the sealing gasket 72, the connecting pipe 21, and the emergency shut-off valve of the refueling island are fixedly connected by a screw. In some specific implementations, each of the flow meters 26 is fixedly connected to an adjusting wheel, with the adjusting wheel facing outwards from the fuel dispenser 1; It should be noted that the outer side of the fuel dispenser 1 is the side used by the operator of the fuel dispenser 1; In some specific implementation schemes, a number of vacuum pumps are fixedly connected inside the fuel dispenser 1 via pipes. The vacuum pumps are evenly arranged inside the fuel dispenser 1 and are all located on the same horizontal plane. The working principle of this utility model is as follows: When installing the hydraulic area of ​​the fuel dispenser 1, first place the connecting pipe 21 inside the emergency shut-off valve of the fuel island, then place the sealing gasket 72, and fit one end of the adjusting pipe 22 with the sealing gasket 72. Rotate the adjusting pipe 22 to change the position of the other end of the adjusting pipe 22. Fix the flow meter mounting plate 51 and the filter mounting plate 52 inside the fuel dispenser 1. Fix the flow meter 26 to the surface of the flow meter mounting plate 51 with bolts. Then adjust the position of the filter 25 on the surface of the filter mounting plate 52 according to the position of the adjusting pipe 22. When the inlet pipe 23 fits with the adjusting pipe 22, fix the position of the filter 25 and the position of the adjusting pipe 22. Then rotate the mounting ring 61 towards the surface of the adjusting pipe 22 to make the washer 62 fit with the adjusting pipe 22. The assembly is then completed.
