Description

Technical Field

[0001] This application belongs to the technical field of micro unmanned aerial vehicle engines, and particularly relates to an oil supply pipeline. Background Art

[0002] Most of the existing engine oil supply pipelines have a branch for the starting fuel pipeline and the main fuel pipeline respectively to supply fuel to the engine. In this way, separate oil pumps and separate solenoid valves are required to control the opening and closing of the starting fuel pipeline and the main fuel pipeline. However, this structure requires a large number of pipeline lines and oil pumps to be installed at the engine. These connecting pipelines and oil pumps will be relatively messy and not easy to organize inside the engine. And due to too many connecting interfaces, it is easy to cause many connection hidden dangers, such as the fracture of the connecting interface, oil leakage, etc., affecting the normal operation of the engine. Therefore, a new technology is proposed. Content of the Utility Model

[0003] The technical problem to be solved by the present utility model is: to solve the deficiencies in the prior art that there are many and complex pipelines and a large number of oil pumps are required, which will occupy the engine space and are prone to cause many connection hidden dangers. Thus, an oil supply pipeline is provided in which the relevant pipelines are integrated into a pipeline integration block, which is easy to install and reduces connection hidden dangers.

[0004] The technical solution adopted by the present utility model to solve its technical problems is:

[0005] An oil supply pipeline includes a pipeline integration block, an oil pump, a delivery channel, solenoid valve 1, solenoid valve 2, a starting fuel pipeline, and a main fuel pipeline. The delivery channel is arranged inside the pipeline integration block. Both the starting fuel pipeline and the main fuel pipeline are communicated with the delivery channel. The oil pump is arranged outside the pipeline integration block. The oil pump is communicated with the delivery channel to deliver a medium to the delivery channel. Solenoid valve 1 and solenoid valve 2 are arranged inside the pipeline integration block. Solenoid valve 1 is used to open and close the starting fuel pipeline, and solenoid valve 2 is used to open and close the main fuel pipeline.

[0006] Furthermore, the oil pump is arranged at the top or side of the pipeline integration block. According to the position of the oil pump set inside the engine space, the input end of the oil pump is connected to one end of the delivery channel. The starting fuel pipeline and the main fuel pipeline are arranged at the bottom of the pipeline integration block. Such a structure enables the pipeline integration block to be an integrated structure with higher structural hardness and strength, improving the service life. This structure matches the internal space condition of the engine.

[0007] Further, the delivery channel includes Channel 1 and Channel 2. Channel 1 is opened from the top surface of the pipeline integration block and enters the pipeline integration block. The top end of Channel 1 is connected to the oil pump. Channel 2 is opened from one side of the pipeline integration block and enters the pipeline integration block. The adjacent ends of Channel 2 and Channel 1 are cooperatively connected. The free end of Channel 2 is sealed by Set Screw 1. Channel 2 is connected to the starting fuel pipeline and the main fuel pipeline. The oil pump is arranged at the top end of the pipeline integration block, and the starting fuel pipeline and the main fuel pipeline are arranged at the bottom end of the pipeline integration block. There must be a turning point in the delivery channel. For the convenience of excavation and manufacturing, the delivery channel is divided into Channel 1 and Channel 2.

[0008] Further, it also includes Channel 3 which is convenient for connecting Channel 1, Channel 2 and excavation. Channel 3 extends from one side of the pipeline integration block to Channel 2 and is connected to Channel 2. Channel 1 is connected to Channel 3. The opening of Channel 3 is sealed by Set Screw 2. Sometimes, it is not possible to directly connect Channel 1 and Channel 2. Therefore, Channel 3 is set up to connect Channel 1 and Channel 2, which is more convenient during processing.

[0009] Further, mounting holes for installing Solenoid Valve 1 and Solenoid Valve 2 are opened on the pipeline integration block. Solenoid Valve 1 and Solenoid Valve 2 are installed in the corresponding mounting holes. The mounting hole can be one, or it can also be two, for installing Solenoid Valve 1 and Solenoid Valve 2 respectively, which is set according to the usage requirements and is more flexible in use.

[0010] The beneficial effects of the present utility model are:

[0011] 1. Integrating the pipelines of the starting fuel and the main fuel can reduce the installation of the oil pumps used and the connecting pipelines. The integrated pipeline integration block is convenient for arrangement, saves space, and reduces connection risks;

[0012] 2. The starting fuel pipeline and the main fuel pipeline can be opened and closed according to the usage requirements, which is convenient for adjusting the pipelines to be connected according to the usage requirements and is more flexible in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment

[0026] This embodiment provides a fuel supply pipeline, including a pipeline integration block 10, an oil pump 20, a delivery channel 120, a first solenoid valve 50, a second solenoid valve 60, a starting fuel pipeline 70, and a main fuel pipeline 80. After the product of the present utility model is installed, the starting fuel pipeline 70 and the main fuel pipeline 80 are located in the combustion chamber of the microengine. The delivery channel 120 is arranged in the pipeline integration block 10. The delivery channel 120 communicates with the starting fuel pipeline 70 and the main fuel pipeline 80. The oil pump 20 conveys a medium to the delivery channel 120. The oil pump 20 is arranged outside the pipeline integration block 10. The first solenoid valve 50 and the second solenoid valve 60 are installed in the pipeline integration block 10. The first solenoid valve 50 opens and closes the starting fuel pipeline 70, and the second solenoid valve 60 opens and closes the main fuel pipeline 80. The valve cores and valve stems of the first solenoid valve 50 and the second solenoid valve 60 do not affect the flow of the medium in the delivery channel 120.

[0027] When the pipeline integration block 10 can be an integrated structure, the structural hardness and strength of the pipeline integration block 10 are higher, and the service life is improved. At this time, the main fuel pipeline 80 can be composed of a first channel 30 and a second channel 40. The first channel 30 is opened from the top surface of the pipeline integration block 10 and enters the pipeline integration block 10. The top end of the first channel 30 communicates with the oil pump 20. The second channel 40 is opened from one side of the pipeline integration block 10 and enters the pipeline integration block 10. The adjacent ends of the second channel 40 and the first channel 30 are cooperatively communicated. The free end of the second channel 40 is sealed by a first set screw 31. The second channel 40 communicates with the starting fuel pipeline 70 and the main fuel pipeline 80. The oil pump 20 can be arranged at the top or side of the pipeline integration block 10. The oil pump 20 is arranged at the top or side of the pipeline integration block 10 according to the position of the oil pump 20 set in the engine space. The starting fuel pipeline 70 and the main fuel pipeline 80 are arranged at the bottom end of the pipeline integration block 10. In this way, there must be a turning point in the delivery channel 120. For the convenience of excavation and manufacturing, the delivery channel is divided into the first channel 30 and the second channel 40.

[0028] It further includes a third channel 90 that facilitates the connection of the first channel 30, the second channel 40, and the excavation. The third channel 90 extends from one side of the pipeline integration block 10 into the second channel 40. The third channel 90 communicates with the second channel 40. The first channel 30 communicates with the third channel 90. The opening of the third channel 90 is sealed by a second set screw 91. Sometimes, it is not possible to directly connect the first channel 30 and the second channel 40. Therefore, the third channel 90 is provided to connect the first channel 30 and the second channel 40, which is more convenient during processing.

[0029] The pipeline integration block 10 is provided with mounting holes 100 for mounting the first solenoid valve 50 and the second solenoid valve 60. The first solenoid valve 50 and the second solenoid valve 60 are installed in the corresponding mounting holes 100. The mounting holes 100 can be one, or can also be two, respectively installing the first solenoid valve 50 and the second solenoid valve 60, which is set according to the use requirements and is more flexible in use.

[0030] When the product of the present utility model is in use:

[0031] First, the second solenoid valve 60 is in the closed state, and the first solenoid valve 50 is in the open state. The starting fuel is pumped from the fuel pump 20 into the pipeline integration block 10, first enters the first channel 30, then enters the second channel 40 through the third channel 90, and flows into the starting fuel pipeline 70 through the gap between the valve stem of the second solenoid valve 60 and the second channel 40 (because when the first solenoid valve 50 is not opened, although fuel can pass through the second channel 40, due to the influence of the first solenoid valve 50, the cross-sectional area of the pipeline decreases, and the fuel throughput decreases accordingly. During the engine starting process, not much fuel is required, so placing the starting fuel pipeline behind the main fuel pipeline 80 will not affect the engine starting process). After a certain amount is output from the starting fuel pipeline 70 to start the engine, the second solenoid valve opens, and the fuel enters the main fuel pipeline 80 and enters the combustion chamber along the main fuel pipeline 80. During the opening process of the second solenoid valve 60, it will not affect the continuous inflow of fuel into the starting fuel channel to maintain the starting process. At the same time, after the main fuel enters the combustion chamber, it participates in combustion to complete the starting transition process. After the starting process is completed, the first solenoid valve 50 closes, and the second solenoid valve 60 is in the open state. The fuel pump 20 continuously pumps fuel into the main fuel pipeline 80 and outputs it to the combustion chamber through the main fuel pipeline 80.

[0032] In summary, the pipeline integration block of the product of the present utility model is an integrally formed structure, and then channels are opened therein to convey the medium. There are no connecting gaps, its structure is stable, and its service life is long; there are also no components such as many exposed pipelines and fuel pumps, which do not occupy the engine space and are also convenient to maintain.

[0033] Inspired by the above ideal embodiments based on this application, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
