[0002] Hydraulic systems are widely used in industrial equipment, automobiles and other mechanical devices to control the direction, pressure and flow rate of fluid. The performance of these systems directly affects the efficiency and stability of the entire device. Therefore, optimizing the design of hydraulic components is crucial for improving overall performance. Traditional hydraulic throttling devices are mainly used to regulate the flow rate of fluid, thereby achieving precise control of the hydraulic system.

[0018] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0019] A throttle block comprises a throttle body 1. The inside of the throttle body 1 is provided with a cavity, one end of the throttle body 1 is provided with an input hole 11, and the other end is provided with an output hole 12. The input hole 11 is in communication with the cavity, and the output hole 12 is also in communication with the cavity. The output hole 12 is arranged in a direction perpendicular to the axis of the throttle body 1. The throttle body 1 is further provided with a flow guide part 13 corresponding to the output hole 12, so that the output hole 12 can more accurately control the direction and amount of fluid flow, thereby improving the adjustment accuracy and stability of the entire system, and achieving the effect of precise throttling control.

[0020] Specifically, the throttling body 1 is provided with an input hole 11, an output hole 12 and a flow guide part 13. Among them, the cavity is the main working chamber during throttling, and different shapes can be set inside to adapt to different fluid flow characteristics. For example, the cavity can be designed as a circle, an ellipse, and a polygon to increase the complexity of fluid passing through, thereby effectively improving the fluid dynamics characteristics and reducing the generation of turbulent flow. This cavity design can significantly improve the throttling accuracy and ensure that the fluid is more evenly distributed in different directions and positions. The input hole 11 is the inlet of the main fluid 1, and its position, size and arrangement are set according to the specific application scenario. For example, the input hole 11 can be designed as a straight hole or an inclined hole in two basic types to better adapt to different inflow medium characteristics. The main function of the input hole 11 is to ensure that the fluid enters the cavity inside the throttling part smoothly, thereby achieving effective throttling. Specifically, if a straight hole design is adopted, the fluid can enter the cavity inside in a straight line, reducing the pressure loss caused by the shape change at the inlet; if an inclined hole design is selected, the fluid flow direction can be guided to a certain extent, increasing its turbulent flow stability. Similarly, the output hole 12 is the outlet of the throttled fluid, and its position and size are also adjusted according to actual needs. The diameter of the output hole 12 gradually converges from the outer wall to the inner wall of the throttling body 1, which helps to adjust the flow rate when passing through the output hole 12, so that the throttled fluid is output in a more stable state, avoiding the turbulent flow caused by excessive speed. In addition, the number of output holes 12 is four, and they are evenly arranged along the circumference of the throttling body 1, which makes the fluid flow out of the cavity more diversified, improving the flexibility and adaptability of the throttling system.

[0021] The flow guide part 13 is mainly to improve the fluid distribution near the output hole 12, thereby eliminating the uneven flow distribution phenomenon. The flow guide part 13 is designed in various structural combinations such as trapezoidal, semicircular or wedge-shaped to cope with different types of working condition requirements and improve throttling stability. For example, the flow guide part 13 can be provided with a flow guide slope 131, which corresponds to the output hole 12 and is arranged along the circumference of the throttling body 1. The flow guide slope 131 can be designed as a straight line or a curve, which can better guide the fluid flow direction and make it discharge along the predetermined path. At the same time, the included angle α between the flow guide slopes 131 is 80°. Such an angle setting is beneficial to maintaining the best throttling state, that is, to maximize the reduction of energy loss while ensuring the throttling efficiency.

[0022] In addition, the flow guide part 13 is also provided with an assembly protrusion 132, which is located on the side of the flow guide part 13 away from the output hole 12 and protrudes from the surface of the flow guide part 13. The main function of the protrusion is to facilitate the connection and positioning between the flow guide part 13 and the throttling body 1, and to fix it. Specifically, the assembly protrusion 132 can be designed in various forms such as cylindrical or pyramid, so as to enhance the stability during installation and prevent displacement or falling phenomenon during use. The throttling protrusion 14 is arranged on the side of the output hole 12 away from the flow guide part 13, and extends from the outer wall to the inner wall of the throttling body 1. The protrusion structure helps to further control the flow direction of the fluid at the output hole 12, ensuring a more uniform speed distribution. The side surface of the throttling protrusion 14 can be designed as a plane or a wave shape to adapt to different fluid characteristics and improve the throttling effect. The throttling body 1 is also provided with a plurality of positioning grooves 15 arranged on the outer wall of the throttling body 1 from one end to the other end. The positioning grooves 15 not only help to improve the overall strength of the throttling block, but also provide convenient positioning function for external assembly. The number of each group of positioning grooves 15 can be set to two or four; the width and depth can be flexibly adjusted according to actual assembly needs.

[0023] The implementation principle of the embodiment is:

[0024] The throttling block realizes more accurate regulation of fluid flow through single-hole input structure, multiple tapered output holes 12 and specially designed flow guide part. Compared with traditional single-opening throttling device, the throttling block provided by the application has obvious advantages in high-precision regulation occasions. Through the optimization design of the structure of the throttling body 1, it not only meets the needs of complex application scenarios, but also improves the throttling control precision and stability. Specifically, by introducing a variety of shape cavities in the throttling body 1, smooth transition of fluid in the internal complex path is realized; the use of tapered hole design can reduce energy loss and effectively avoid turbulence phenomenon on the basis of ensuring sufficient flow regulation space; the four-hole input structure and multiple positioning grooves make the throttling block better adapt to various external connection requirements, and enhance the compatibility of the system. In summary, the throttling block of the utility model has been optimized and upgraded in structure, which not only meets the high-precision regulation requirements, but also improves the overall performance of the system, and has strong application value.

[0025] Embodiment 2

[0026] The difference between the embodiment and the above-mentioned embodiments is that the design of the throttling protrusion 14 and the specific structure of the assembly protrusion 132 are further optimized. The throttling protrusion 14 adopts a wave shape, and can be individually adjusted in size and shape according to the fluid characteristics, so that it can provide stable and consistent throttling effect for different fluid types. For example, for fluids with high viscosity or more impurities, a larger size wave-shaped throttling protrusion 14 can be selected to increase its anti-clogging ability; and for clean and low viscosity fluids, a smaller size design can be selected to ensure the throttling precision. In addition, in order to improve the connection strength between the throttling protrusion 14 and the throttling main body 1, a heat insulation gasket can be added to the contact surface between the two, or a high-strength adhesive can be used for fixation, so as to avoid the loosening problem that may occur during long-term use.

[0027] In terms of the assembly protrusion 132, a two-layer structure is proposed: the bottom layer is a cylindrical design to support the weight of the entire assembly; the upper layer is a rhombic quadrilateral cross-section structure provided with a plurality of recessed grooves to form a friction surface, thereby increasing the contact area between the components and improving the grip during assembly. This design not only simplifies the assembly process but also effectively resists the risk of loosening caused by external impact. In this way, the product stability performance is greatly improved without changing the position of the output hole 12 and the angle of the flow guide surface, ensuring that the angle does not deform after multiple assembly and disassembly operations.

[0028] The implementation principle of the embodiment is:

[0029] Through the further structural design improvement of the throttling protrusion 14 and the assembly protrusion 132, the overall stability performance of the throttling block is greatly increased. Compared with conventional designs, the introduction of more parameter variation possibilities enables the throttling block to perform outstanding performance in a wider range of application scenarios, especially in the case of special fluid properties, it can still maintain good throttling effect. For example, when dealing with high viscosity oil or liquid containing small particle impurities, the wave-shaped throttling protrusion 14 scheme can significantly improve its service life and reduce maintenance costs caused by clogging. The improved solid assembly protrusion 132 structure strengthens the external fixation of the entire device, providing reliable protection for extreme working conditions or frequent assembly and disassembly requirements. Therefore, based on the reasonable optimization of the original design, the utility model not only meets the higher precision adjustment demand, but also enhances the long-term stable operation ability of the system, and has good market potential.
