Description

Technical Field

[0001] This utility model relates to the field of fuel delivery technology, specifically a pipeline connection and fuel fluid distribution structure. Background Technology

[0002] Pipeline connections and fuel fluid distribution structures are core components of fuel supply systems, primarily used to achieve efficient fuel transmission and precise distribution.

[0003] However, most of the connectors on the current fuel distribution pipes are welded to the surface of the pipe. Welding is a permanent connection and is not easy to remove or replace. At the same time, the fuel distribution structure needs to be in a high-temperature environment for a long time during operation. Such an environment will cause the connectors and pipes to deform, which will not only lead to fuel leakage, but also cause safety hazards. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Example 1 Please see Figures 1-4 This utility model provides a technical solution: A pipeline connection and fuel fluid distribution structure includes a distribution pipe 1, a connection mechanism is provided on the surface of the distribution pipe 1, and a buffer mechanism and an adjustment mechanism are provided inside the connection mechanism; The connecting mechanism includes a fixed plate 6 set on the surface of the distribution pipe 1. An adjusting plate 7 is slidably connected inside the fixed plate 6. Clamping plates 8 are fixedly connected to the top of the fixed plate 6 and the bottom of the adjusting plate 7. Connecting pieces 9 are fixedly connected to the two clamping plates 8 away from the connection between the fixed plate 6 and the adjusting plate 7. The detachable connecting mechanism allows the connecting pieces 9 to be removed from the distribution pipe 1 separately, which is convenient for replacement and maintenance.

[0021] The buffer mechanism includes a buffer groove 10 disposed inside the clamping plate 8, a sliding column 11 fixedly connected inside the buffer groove 10, and a spring 12 disposed on the outer surface of the sliding column 11.

[0022] A sleeve 13 is slidably installed inside the buffer groove 10, and a buffer plate 14 is fixedly connected to the end of the sleeve 13 away from the buffer groove 10.

[0023] The clamping plate 8 connected to the fixing plate 6 has a downward-facing internal buffer groove 10, while the clamping plate 8 connected to the adjusting plate 7 has an upward-facing internal buffer groove 10. In some special installation cases, the distribution pipe 1 is usually rigidly connected to the engine block. When abnormal vibration occurs during engine operation, it will cause the distribution pipe 1 to shake. The buffering mechanism can buffer the distribution pipe 1, thereby avoiding fuel leakage and equipment failure caused by shaking.

[0024] When in use, first determine the distance between the fixed plate 6 and the adjusting plate 7 in the connecting mechanism according to the size of the distribution pipe 1. Then, use the connector 9 to install the distribution pipe 1 in the designated position. At this time, the top end face of the distribution pipe 1 contacts the buffer plate 14 at one end of the fixed plate 6, and the bottom end face of the distribution pipe 1 contacts the buffer plate 14 at one end of the adjusting plate 7. This is to prevent the distribution pipe 1 from shaking, which could lead to fuel leakage and equipment failure. The fuel pump draws fuel from the fuel tank, which is then pre-purified by a coarse filter and an oil-water separator before being pressurized and delivered to the fuel distribution pipe 1. The fuel pressure regulator 3 monitors the fuel pressure in real time and dynamically adjusts it through a feedback control system to ensure stable fuel pressure in the distribution pipe 1. The fuel is then distributed to each injector 5. The fuel delivered by the distribution pipe 1 is atomized by the injectors 5 and enters the cylinder. Finally, any uninjected fuel returns to the fuel tank through the return pipe, forming a closed-loop system.

[0025] Example 2 Please see Figures 1-4 This utility model provides a technical solution: The adjustment mechanism includes an inner plate 15 that is slidably installed inside the fixed plate 6. An elastic element 16 is provided between the bottom end of the inner plate 15 and the bottom end of the fixed plate 6. One end of the adjustment plate 7 located inside the fixed plate 6 is fixedly connected to the inner plate 15. The distance between the fixed plate 6 and the adjustment plate 7 can be adjusted through the adjustment mechanism, so that the connection mechanism can adapt to the distribution pipes 1 of different sizes and dimensions, thereby improving the wide applicability of the connection mechanism.

[0026] One end of the distribution pipe 1 is provided with a mounting base 2, and a fuel pressure regulator 3 is fixedly installed inside the mounting base 2. The end of the mounting base 2 opposite to the fuel pressure regulator 3 is provided with an inlet 4. The fuel pressure regulator 3 can maintain a constant pressure difference between the fuel distribution pipe 1 and the intake manifold, ensuring that the fuel injection quantity is determined only by the opening time of the injector 5, thereby ensuring stable operation of the engine under different operating conditions.

[0027] Multiple fuel injectors 5 are evenly installed at one end of the distribution pipe 1. The main function of the fuel injectors 5 is to atomize the fuel into tiny particles and precisely inject them into the engine combustion chamber or intake manifold to achieve timed, quantitative, and pressured fuel injection.

[0028] Unlike Embodiment 1, the distance between the fixed plate 6 and the adjusting plate 7 can be adjusted by the adjusting mechanism, so that the connecting mechanism can adapt to the distribution pipe 1 of different sizes and dimensions, thereby improving the wide applicability of the connecting mechanism. Furthermore, the elastic element 16 ensures that both buffer plates 14 are tightly fitted with the distribution pipe 1 to achieve a buffering effect.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
