Description

Technical Field

[0001] The utility model relates to the technical field of oil supply valves, in particular to an oil supply valve with good stability. Background Art

[0002] The oil supply valve, as a vital component in the hydraulic system, has the core function of providing a stable and reliable oil source for the system to ensure the smooth operation of the entire system. It is not only responsible for controlling the supply and flow of liquid or gas, but also plays a vital role in the fuel system. The oil supply valve is specifically used to regulate the flow of fuel to ensure that the fuel can be supplied to the engine or combustion equipment at an appropriate pressure and flow, thereby ensuring the efficient operation of these core components.

[0003] Most of the existing oil supply valves lack a mechanism to maintain a stable oil supply flow rate, resulting in large fluctuations in the flow rate during the oil supply process, making it difficult to achieve smooth oil supply, and lack an effective over-pressure protection device. Once the oil supply flow rate fluctuates significantly and is accompanied by over-pressure, it will not only significantly increase the risk of oil supply failure, but is more likely to cause serious damage to related equipment and may even cause serious safety accidents. Therefore, the utility model provides an oil supply valve with good stability to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a fuel supply valve with good stability. During use, the fuel is introduced into the interior of the valve body through the fuel inlet pipe, so that the fuel drives the rotating vane to rotate, and the rotating vane can adjust the oil output to achieve stable fuel supply. When the pressure inside the valve body rises to a certain threshold, the fuel will exert pressure on the block to make it slide, so that the fuel returns to the interior of the fuel inlet pipe through the return pipe, thereby preventing overpressure and ensuring the safe and stable operation of the fuel supply system.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An oil supply valve with good stability comprises a valve body and a shell, wherein a stabilizing mechanism is arranged inside the valve body, and the stabilizing mechanism comprises a rotating shaft, a ratchet, a ratchet pawl, a second spring and a plurality of rotating leaves;

[0007] A compression spring is fixedly arranged inside the valve body, a clamping block is fixedly arranged at the lower end of the compression spring, a pressure relief port is opened on one side of the valve body, an oil return pipe is fixedly arranged on one side of the valve body, an oil inlet pipe is fixedly arranged on one side of the valve body, and a sealing ring is clamped inside the clamping block;

[0008] Through the above technical solution, when oil enters the valve body, it will push the rotating blade to drive the rotating shaft to rotate, so that the oil supply is uniform and stable. When the pressure in the valve body is too high, the pressurized fuel will push the block and drive it to slide along the inside of the valve body, so that the fuel returns to the inside of the oil inlet pipe through the return pipe, effectively reducing the pressure inside the valve body.

[0009] Further, the upper end of the rotating shaft is rotatably arranged inside the valve body near the upper end, the ratchet wheel is fixedly arranged inside the rotating shaft near the upper end, the multiple rotating leaves are fixedly arranged on opposite sides of the rotating shaft near the lower end, and the outer ends of the multiple rotating leaves are rotatably arranged inside the valve body near the lower end;

[0010] Through the above technical solution, when oil enters the valve body, it will push the rotating blade to rotate, so that the rotating blade drives the rotating shaft to rotate inside the valve body, and the rotating blade makes the oil supply stable and uniform.

[0011] Further, one side of the second spring is fixedly arranged inside the valve body near one side, the other side of the second spring is fixedly arranged on one side of the pawl, the other side of the pawl is meshedly connected to the outside of the ratchet, and one side of the pawl is rotatably arranged inside the valve body near one side;

[0012] Through the above technical solution, when the ratchet wheel rotates, it will be gap locked by the pawl, and the oil backflow can be prevented, thereby improving the stability of oil supply.

[0013] Furthermore, the output end of the oil return pipe is fixedly arranged on the upper end of the outer portion of the oil inlet pipe, and the outer portion of the valve body is sleeved inside the outer shell;

[0014] Through the above technical solution, the oil return pipe can output the oil inside it to the inside of the oil inlet pipe, thereby playing a protective role, and the outer shell protects the internal valve body.

[0015] Furthermore, an oil outlet pipe is fixedly arranged on one side of the valve body, and the oil inlet pipe is sleeved inside the housing on a side opposite to the oil outlet pipe;

[0016] Through the above technical solution, the oil outlet and the oil inlet are used to control the flow direction of the fuel to ensure stable fuel supply operation, and the outer shell plays a protective role to ensure the stability and safety of the internal components of the valve body.

[0017] Furthermore, two connecting blocks are rotatably provided at both ends of the valve body, and sliders are rotatably provided at opposite ends of the four connecting blocks, and sliding grooves are provided at both ends of the inner part of the shell;

[0018] Through the above technical solution, when the valve body is vibrated, the connecting block at the upper end of the valve body will drive the slider to slide inside the slide groove, thereby offsetting the vibration, so that the valve body can operate stably.

[0019] Furthermore, first springs are fixedly arranged on opposite sides of the four sliders, and opposite ends of the four sliders are slidably arranged in the two slide grooves respectively;

[0020] Through the above technical solution, when the slider slides inside the slide groove, the slider will squeeze the first spring to cause it to shrink, and the slide groove can play a guiding role, so that the slider runs stably.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a fuel supply valve with good stability. When in use, the fuel enters the valve body through the fuel inlet pipe, driving the rotating blades on the rotating shaft to rotate, which not only ensures the smooth guidance of the fuel, but also realizes precise control of the output fuel amount through adjustment of the different positions of multiple rotating blades, ensuring the continuous and stable supply of fuel. When the rotating shaft rotates, it will synchronously drive the ratchet and the pawl to operate. The ratchet and the pawl can effectively prevent instability in the fuel supply process, ensuring a smooth and continuous fuel supply process.

[0023] 2. The utility model proposes a fuel supply valve with good stability. When the pressure inside the valve body rises to a preset safety threshold, the pressure of the fuel will push the block through the pressure relief port, causing it to overcome the resistance of the compression spring and slide inside the valve body, thereby opening the pressure relief channel, allowing excess fuel to safely return to the inside of the fuel inlet pipe through the return pipe, thereby effectively reducing the pressure inside the valve body and forming an overpressure protection mechanism, which can not only prevent potential dangers caused by overpressure, but also ensure the safety and stable operation of fuel supply.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-5 , an embodiment provided by the utility model:

[0033] A fuel supply valve with good stability, comprising a valve body 3 and a housing 1, wherein a stabilizing mechanism 8 is arranged inside the valve body 3, the stabilizing mechanism 8 comprising a rotating shaft 801, a ratchet 802, a pawl 803, a second spring 804 and a plurality of rotating leaves 805, wherein the upper end of the rotating shaft 801 is rotatably arranged inside the valve body 3 near the upper end, the ratchet 802 is fixedly arranged inside the rotating shaft 801 near the upper end, the plurality of rotating leaves 805 are fixedly arranged on the outer side of the rotating shaft 801 near the lower end on two opposite sides, the outer sides of the plurality of rotating leaves 805 are rotatably arranged inside the valve body 3 near the lower end, one side of the second spring 804 is fixedly arranged inside the valve body 3 near one side, the other side of the second spring 804 is fixedly arranged on one side of the pawl 803, the other side of the pawl 803 is meshedly connected to the outer side of the ratchet 802, and one side of the pawl 803 is rotatably arranged inside the valve body 3 near one side;

[0034] During the fuel supply, the fuel is introduced into the core area of ​​the valve body 3 through the fuel inlet pipe 2, and then pushes the rotating blades 805 on the rotating shaft 801, causing it to rotate inside the valve body 3, which not only ensures the smooth transmission of the fuel in the valve body 3, but also through the precise arrangement and position change of multiple rotating blades 805, it realizes the fine adjustment of the fuel output, thereby ensuring the continuous stability and high accuracy of the fuel supply. As the rotating shaft 801 rotates, the ratchet 802 thereon and the ratchet 803 engaged with it work immediately, which not only prevents the fuel from flowing back, but also makes the fuel supply smooth and continuous, so that the fuel supply is smooth and continuous, thereby making the fuel supply valve run stably.

[0035] A compression spring 9 is fixedly arranged inside the valve body 3, a clamping block 10 is fixedly arranged at the lower end of the compression spring 9, a pressure relief port 11 is opened on one side of the valve body 3, an oil return pipe 5 is fixedly arranged on one side of the valve body 3, an oil inlet pipe 2 is fixedly arranged on one side of the valve body 3, a sealing ring 12 is clamped inside the clamping block 10, an output end of the oil return pipe 5 is fixedly arranged on the upper end of the outside of the oil inlet pipe 2, the outside of the valve body 3 is sleeved inside the housing 1, an oil outlet pipe 13 is fixedly arranged on one side of the valve body 3, and the opposite side of the oil inlet pipe 2 and the oil outlet pipe 13 is sleeved inside the housing 1;

[0036] When the pressure in the valve body 3 rises to a preset safety limit, the excessive pressure will enter the pressure relief port 11, thereby driving the block 10 to resist and exceed the reverse resistance of the compression spring 9, so that the block 10 slides and rises inside the valve body 3, and then the fuel inside the valve body 3 is depressurized, and the fuel can be safely guided back to the oil inlet pipe 2 through the return pipe 5. The return pipe 5 is relatively long, which effectively reduces the excessive pressure inside the valve body 3, not only successfully avoiding various risks that may be induced by overpressure, but also further consolidating the stability and safety of the oil supply process, ensuring the long-term reliable operation of the oil supply valve, when the pressure relief is completed, the compression spring 9 rebounds, so that the block 10 is accurately clamped on the outside of the pressure relief port 11, and the sealing ring 12 inside the block 10 can provide additional sealing function to prevent fuel leakage, and the housing 1 provides a solid protection for the internal components of the oil supply valve, thereby improving the stable operation of the oil supply valve.

[0037] Two connecting blocks 4 are rotatably provided at both ends of the valve body 3, and sliders 7 are rotatably provided at opposite ends of the four connecting blocks 4, and slide grooves 14 are provided at both ends of the housing 1, and first springs 6 are fixedly provided at opposite sides of the four sliders 7, and opposite ends of the four sliders 7 are slidably provided in the two slide grooves 14 respectively;

[0038] When encountering external vibration interference, the connecting block 4 on the valve body 3 immediately guides the slider 7 to slide in the slide groove 14 opened inside the shell 1. The enhanced friction between the slider 7 and the slide groove 14 during the sliding process effectively absorbs the vibration energy and squeezes the first spring 6, thereby improving the valve's resistance to external vibration. Even in extremely unfavorable working environments, the valve body 3 can still maintain its operational stability and reliability, and continuously ensure the smooth operation of the oil supply system. When the valve body 3 is affected by vibration, the connecting block 4 on the valve body 3 will prompt the slider 7 to slide in the slide groove 14 opened inside the shell 1. During the sliding process of the slider 7, a large friction force will be generated between the slider 7 and the slide groove 14, which can effectively offset the energy generated by the vibration. At the same time, the movement of the slider 7 will compress the first spring 6, and the compression of the spring will absorb and store the vibration energy, thereby reducing the direct impact of the vibration on the valve body 3, improving the valve's resistance to external vibration, and ensuring that the valve body 3 can still work stably and reliably under harsh working conditions.

[0039] Working principle: During the fuel supply stage, the fuel is transported to the inside of the valve body 3 through the fuel inlet pipe 2, and then the rotating blade 805 on the rotating shaft 801 is pushed to rotate, thereby ensuring the circulation of the fuel in the valve body 3. The rotating blade 805 controls the fuel output flow rate to ensure the long-term stability of the fuel supply. At the same time, the operation of the rotating shaft 801 drives the ratchet 802 and the pawl 803 to operate. The ratchet 802 and the pawl 803 will effectively prevent the fuel from flowing back, and also enhance the smoothness of the fuel supply process. The operation of the fuel supply valve lays a solid and stable foundation, and then the fuel flows into the fuel outlet pipe 13. When the internal pressure of the valve body 3 exceeds the set safety value, the over-pressure fuel will be directed to the pressure relief port 11, and push the block 10 to apply pressure to the compression spring 9, so that the block 10 moves upward along the inside of the valve body 3, and the slider 7 slides to make the excess fuel return to the inside of the fuel inlet pipe 2 through the return pipe 5, so that the pressure in the valve body 3 is effectively relieved, preventing the hidden dangers caused by overpressure, and providing a solid guarantee for the long-term stable operation of the fuel supply valve.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
