Description

Technical Field

[0001] This utility model relates to the ball structure of an integrated noise reduction and flow stabilization regulating ball valve. Background Technology

[0002] A ball valve is a valve in which the ball is driven by the valve stem and rotates around the valve axis. It can be used for fluid regulation and control. Traditional ball valve cores have the following problems in the flow regulation process: 1) Insufficient flow control accuracy: A single-structure valve core is difficult to achieve multi-stage regulation, resulting in poor flow stability; 2) Large noise and pressure fluctuations: Turbulence is easily generated when the fluid passes through the valve core, causing noise and pressure fluctuations. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a ball structure for an integrated noise-reducing and flow-stabilizing regulating ball valve. Through a multi-stage structural design, it achieves precise flow regulation, pressure reduction and flow stabilization, and noise suppression, effectively solving the problems mentioned in the background art.

[0004] The technical solution adopted in this utility model is:

[0005] An integrated noise-reducing and flow-stabilizing ball valve has a ball structure, including a ball with a fluid channel and a valve core fixed to one end of the fluid channel inlet. The valve core includes a support ring that matches the fluid channel. The support ring has a large through hole on its left side that penetrates both the inside and outside of the support ring, and a pressure-reducing and flow-stabilizing fluid channel on its right side. The pressure-reducing and flow-stabilizing fluid channel is densely covered with through holes penetrating both the inside and outside of the support ring. The middle part of the through hole is a bent channel, and the inner diameter of the through hole gradually increases from the inlet to the outlet.

[0006] Preferably, the large through hole is crescent-shaped.

[0007] Preferably, one end of the inlet of the pressure-reducing and stabilizing fluid protrudes outward, forming a spherical structure with the sphere.

[0008] Preferably, the 0-70° spherical surface of the valve core is for pressure reduction and fluid stabilization, and the 70-90° spherical surface is for large through holes.

[0009] Preferably, an oblique hole is provided on the left side of one end of the fluid channel outlet.

[0010] Preferably, the fluid channel is provided with a step that matches the support ring, and the support ring is positioned axially by the step.

[0011] Preferably, a weld groove is provided at one end of the fluid channel inlet, and the valve core is fixed to the ball by welding.

[0012] Preferably, the valve core is formed by metal 3D printing.

[0013] This utility model, through its innovative multi-level partition structure design and metal 3D printing process, successfully solves the pain points of traditional ball valves, such as low flow control accuracy, high noise, and high manufacturing cost, and has significant technical advantages and market application potential.

[0014] The innovative points of this utility model are:

[0015] Multi-level partitioning structure design:

[0016] 0-70° spherical region: The pressure-reducing and fluid-stabilizing system is made of densely distributed through holes. The middle of the through holes is a bent channel, and the inner diameter increases step by step from the inlet to the outlet. This design achieves the gradual reduction of fluid pressure through a multi-stage stepped expansion structure, reducing turbulence impact and achieving the effects of flow stabilization and noise reduction.

[0017] 70-90° spherical area: A crescent-shaped large through hole is set. The opening of the crescent hole is adjusted by rotating the valve core, which provides higher flow capacity when the flow demand increases. Combined with the front-end flow stabilization function, it realizes a smooth transition and improved accuracy of flow regulation.

[0018] Inclined outlet design: The inclined hole at the fluid channel outlet optimizes the fluid output path, reduces local eddies, and further improves flow efficiency.

[0019] Manufacturing process innovation: The valve adopts a combination structure of ball and valve core welding, and the valve core is formed by metal 3D printing in one piece. This overcomes the limitations of traditional processing technology on complex internal structures (such as bent channels, crescent holes, and oblique holes), significantly reducing manufacturing costs and cycle time, while ensuring structural accuracy and consistency.

[0020] Multifunctional integration: It integrates pressure reduction, flow stabilization, noise reduction and flow regulation functions into a single valve core, breaking through the limitations of the traditional single-function design of ball valves. The synergistic effect of honeycomb through holes and crescent holes can take into account both the fine control under low opening degree and the flow increase requirements under high opening degree.

[0021] The beneficial effects of this utility model are:

[0022] 1) Significantly improved flow control accuracy:

[0023] Multi-stage adjustment mechanism: The honeycomb orifice in the 0-70° region gradually reduces pressure through the bending channel to suppress sudden flow changes; the crescent orifice in the 70-90° region provides linear flow gain, achieving a smooth transition from low flow to high flow, and the adjustment accuracy is better than that of traditional single-stage valve cores.

[0024] 2) Noise reduction and current stabilization performance optimization:

[0025] Stepped pressure reduction: The progressively enlarged structure of the through-hole reduces the fluid velocity gradient, decreases turbulence and cavitation, and reduces noise by 20%-30%;

[0026] Inclined orifice flow guidance: The inclined orifice at the outlet guides the fluid to be output in a set direction, avoiding backflow and local pressure fluctuations, further stabilizing the flow rate and reducing noise;

[0027] 3) Manufacturing cost and efficiency advantages:

[0028] 3D printing technology: Compared with traditional multi-process processing, the one-piece molded valve core reduces material waste and assembly errors, reduces manufacturing costs by about 40%, and is suitable for small-batch customized production;

[0029] 4) Applicability extension:

[0030] Multi-scenario adaptability: This structure can be widely used in high-pressure and high-noise sensitive environments in fields such as petroleum, chemical industry, and water treatment, meeting the fluid control needs under complex working conditions. Attached Figure Description

[0045] like Figure 1-7As shown, an integrated noise reduction and flow stabilizing ball valve has a ball structure, including a ball 1, on which a fluid channel 2 is provided, and a valve core 3 fixed at one end of the inlet of the fluid channel 2. The valve core 3 includes a support ring 31 that matches the fluid channel 2. The left side of the support ring 31 has a large through hole 32 that penetrates the inside and outside of the support ring 31, and the right side has a pressure reducing and fluid stabilizing 33. The pressure reducing and fluid stabilizing 33 is densely covered with through holes 34 that penetrate the inside and outside of the support ring 31. The middle part of the through hole 34 is a bent channel 35, and the inner diameter of the through hole 34 gradually increases from the inlet to the outlet.

[0046] The large through hole 32 is crescent-shaped.

[0047] The inlet end of the pressure-reducing and stabilizing fluid 33 protrudes outward, forming a spherical structure with the sphere 1.

[0048] The 0-70° spherical surface of the valve core 3 is a pressure-reducing and fluid-stabilizing surface 33, and the 70-90° spherical surface is a large through hole 32.

[0049] An oblique hole 4 is provided on the left side of one end of the fluid channel 2 outlet.

[0050] The fluid channel 2 is provided with a step 21 that matches the support ring 31, and the support ring 31 is positioned axially by the step 21.

[0051] The inlet end of the fluid channel 2 is provided with a weld groove 22. The valve core 3 is fixed inside the ball 1 by welding. When welding the valve core 3 to the ball 1, welding can be carried out in two places to achieve good welding strength. One welding is carried out using the weld groove 22, and the other welding position is the position where the valve core 3 connects with the step 21. In this way, the welding of both ends of the valve core 3 is realized, which has good welding strength.

[0052] The valve core 3 is formed by metal 3D printing.

[0053] This invention achieves precise fluid regulation, pressure stabilization, and noise suppression through a multi-level partitioned structural design and integrated metal 3D printing manufacturing. Its core working principle is as follows:

[0054] 1. Valve core rotation controls valve opening:

[0055] The ball drives the valve core to rotate around the axis (0-90°) via the valve stem, thereby adjusting the flow cross-sectional area of ​​the fluid.

[0056] 0-70° opening: Primarily for pressure reduction and fluid stabilization, achieving fine control at low flow rates;

[0057] 70-90° opening: mainly crescent-shaped large through holes to provide a high flow channel.

[0058] 2. Multi-stage voltage reduction and current stabilization mechanism:

[0059] 0-70° region (pressure reduction and fluid stability):

[0060] The valve core surface is covered with through holes, and the middle of the hole is a bent channel. The inner diameter increases gradually from the inlet to the outlet.

[0061] When fluid enters the through hole, the flow velocity decreases step by step due to the channel bends and inner diameter expansion, forming a stepped pressure drop, reducing turbulence and cavitation, thereby suppressing noise and pressure fluctuations;

[0062] The geometric design of the bend in the channel forces the fluid path to change, further dispersing energy and enhancing the flow stabilization effect;

[0063] 70-90° area (crescent-shaped large through hole):

[0064] When the valve core rotates to more than 70°, the crescent-shaped large through hole gradually opens, providing a larger flow area;

[0065] Since the flow has been stabilized by pressure reduction in the 0-70° range, the fluid velocity is slow when it enters the large through-hole, avoiding pressure fluctuations caused by sudden increases in flow rate and achieving a smooth transition.

[0066] 3. Optimization of flow guidance at the inclined hole outlet:

[0067] An oblique hole is provided at the outlet of the fluid channel, forming a specific angle (such as 15-30°) with the channel axis.

[0068] The oblique orifice guides the fluid to be output in a set direction, reducing local eddies and backflow at the outlet, and further improving flow efficiency and stability;

[0069] 4. Structural advantages of 3D printing technology:

[0070] The valve core is integrally molded using metal 3D printing technology to ensure the precise manufacturing of complex internal structures (such as bent channels, crescent holes, and oblique holes);

[0071] Micro-channels and gradient inner diameter structures that are difficult to process using traditional techniques can be reproduced with high precision through 3D printing, reducing processing costs and assembly errors.

[0072] Phased Work Details:

[0073] Low opening stage (0-70°):

[0074] When fluid passes through the through-hole of the pressure-reducing and fluid-stabilizing system, the flow velocity gradually decreases due to the tortuous channel and the progressively enlarging inner diameter, and the pressure energy is converted into potential energy, reducing turbulent impact.

[0075] The multi-stage pressure reduction structure suppresses fluid cavitation, reducing noise by 20%-30%.

[0076] The damping effect of the bent channel stabilizes the flow rate, making it suitable for fine-tuning scenarios (such as micro-feeding in chemical reactors).

[0077] High opening stage (70-90°):

[0078] The crescent-shaped large through-hole is fully open, providing a high-flow channel;

[0079] The pressure reduction and flow stabilization function ensures that the fluid has a uniform flow velocity when entering the large through hole, avoiding the problem of sudden pressure drop under high opening degree of traditional ball valves;

[0080] Combined with inclined hole flow guidance, the flow rate is linearly increased, making it suitable for high flow rate demand scenarios (such as rapid drainage of water treatment systems).

[0081] Dynamic adjustment process:

[0082] When the valve core rotates from 0° to 90°, the flow contribution ratio of the honeycomb through holes and the crescent holes changes dynamically, achieving stepless adjustment;

[0083] The flow curve transitions smoothly, avoiding the "step-like" flow changes of traditional ball valves and improving control accuracy.

[0084] Synergistic effects and technological advantages:

[0085] Noise reduction and flow stabilization: The stepped pressure reduction of the bent channel and the flow guidance of the inclined hole work together to reduce turbulent noise and stabilize the pressure.

[0086] Extended flow rate adjustment range: honeycomb-shaped through holes provide precise control of low flow rates, while crescent-shaped holes meet high flow rate requirements, covering a wider range of operating conditions.

[0087] Process adaptability: 3D printing supports the rapid manufacturing of complex structures and is suitable for customized production (such as special media or high-pressure environments).

[0088] Application scenario example:

[0089] Oil pipelines: During high-pressure oil transportation, multi-stage pressure reduction reduces pipeline vibration and noise, while precisely regulating flow rate;

[0090] Chemical reaction system: The steady flow characteristics at low opening ensure accurate addition of reactants, while high opening supports rapid discharge;

[0091] Water treatment system: The oblique hole design reduces outlet eddies, prevents impurity deposition, and extends valve service life.

[0092] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
