Description

Technical Field

[0001] This invention relates to the field of ball valve protection device technology, specifically a hydroelectric ball valve with a sand-clearing structure. Background Technology

[0002] Currently, ball valves are widely used in hydropower systems, water supply and drainage projects, and sediment transport pipelines due to their flexible opening and closing and superior sealing performance. However, when there is high sediment content in the system, traditional ball valves are prone to erosion and blockage by sediment during long-term operation, leading to problems such as poor opening and closing, sealing failure, and shortened lifespan.

[0003] In existing technologies, the following methods are commonly used to improve the sand-proof performance of ball valves: (1) Single-stage filtration structure: A filter screen or grid is set at the water inlet. Although it can block some particles, the filter screen is very easy to clog and needs to be cleaned frequently. It is not suitable for high flow or continuous operation environments. (2) Power separation system: Separation of mud and sand is achieved by centrifugal separation device driven by external pump or motor, but the structure is complex, energy consumption is high, maintenance cost is high, and it cannot be compactly integrated with valve body; (3) Fixed vortex structure: Some hydraulic devices use fixed guide vanes to form vortexes, which separates sediment by centrifugation. However, the vortex intensity is fixed and it is difficult to adapt to different flow velocity conditions. It is easy to fail at low flow velocity or cause erosion at high flow velocity.

[0004] Furthermore, traditional sedimentation structures often employ static sedimentation or manual sand removal, which can easily lead to sand accumulation dead zones in the flow path, affecting pipeline flow. Additionally, sand discharge ports typically require external power, making it impossible to achieve self-cleaning and low-energy sand removal functions within the valve body. Therefore, this paper researches and improves upon existing problems by providing a water-electric ball valve with a sand-clearing structure to address these issues. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted in this invention is: a water-electric ball valve with a sand-clearing structure, comprising: a ball valve body, a flow guiding component, a swirling flow guiding component, and a sand settling box.

[0007] The flow guiding component is used to adjust the direction of water inflow and the intensity of swirling current; the swirling current diversion component is used to form swirling stratification and centrifugal separation of water and sediment; the sedimentation box is used for non-powered collection, sedimentation, and periodic cleaning of sand particles. Through the combined action of the above structures, a continuous and automatic separation process of "swirling current enhancement - water and sediment stratification - gravity sedimentation" is achieved.

[0008] In this invention, the ball valve body, the flow guiding component, the swirl diversion component, and the sedimentation box form an integrated structure. One end of the ball valve body is fixedly connected to the core flow tube, and both ends of the swirl diversion component are fixedly connected to the flow guiding component and the ball valve body, respectively, forming a continuous fluid passage.

[0009] The valve ring, cone guide seat and impeller in the flow guiding assembly together constitute the fluid guiding unit, the swirling tube and rotating cone in the swirling flow guiding assembly constitute the swirling enhancement unit, and the annular groove and sedimentation tray inside the sedimentation box constitute the sedimentation and sand discharge unit.

[0010] This overall configuration ensures a smooth transition of fluid throughout the entire process from water intake to drainage, significantly improving water and sediment separation efficiency and flow channel unobstructedness.

[0011] In a preferred example, the blades are arranged radially along the outer periphery of the conical guide seat, located between the conical guide seat and the valve ring. The surface of the conical guide seat has a conical structure, causing the incoming water flow to form a ring-shaped dispersed flow. The blades can adjust their tilt angle under the drive of a control servo motor, achieving adaptive control of the inlet swirl angle.

[0012] Specifically, this structure can maintain swirling stability under different flow rates, making the initial angular momentum of the introduced water flow controllable, thereby enhancing the centrifugal separation effect of the downstream swirling diversion component.

[0013] In a preferred example, each pin surface is fixedly connected to a crank rod, and adjacent crank rods are movably connected through connecting rods to form a mechanical linkage mechanism. One blade is fixedly connected to the output end of the control servo motor via a pin, and when the servo motor rotates, it drives the remaining blades to deflect synchronously through the crank rods and connecting rods.

[0014] Specifically, the mechanism can coordinate the guidance of multiple blades, making the swirl more uniform, effectively avoiding flow field instability caused by inconsistent angles, and improving the accuracy of water flow introduction.

[0015] In a preferred example, the outer surface of the rotating cone is provided with several flow dividers and helical blades, the number of which are equal and correspond one-to-one. The helical blades are distributed parallel to the axis of the rotating cone and arranged in a helical tangential direction. After being dispersed by the flow dividers, the water flows along the helical blades to form a helical flow, causing the rotating cone to rotate automatically under the action of fluid kinetic energy.

[0016] Specifically, this structure can form an enhanced swirling field without external drive, improving the tangential velocity of the water flow and centrifugal separation capability, and achieving efficient sand-water stratification.

[0017] In a preferred example, the surface of the rotating cone is provided with a flow divider ring, the surface of which is conical and slides in contact with the inner wall of the cyclone tube, both located in the same vertical plane. The flow divider ring divides the fluid into two layers: clean water enters the core cavity through the drainage slot and is discharged along the core tube; sand-laden water is guided along the outer conical surface of the flow divider ring to the wall of the cyclone tube and is introduced into the sedimentation box through the sand discharge slot.

[0018] Specifically, this layered flow guiding design achieves spatial separation between clean water and sand-containing fluids, preventing sand particles from entering the ball valve body and ensuring that the ball valve sealing parts are not worn.

[0019] In a preferred example, the core tube is arranged coaxially with the rotating cone, and one end of the core tube extends into the core cavity.

[0020] Specifically, this coaxial structure can form a stable low-pressure zone at the center of the vortex, which promotes the automatic convergence of clear water into the core flow tube, achieving complete separation between the central flow and the outer ring sand-containing flow, and significantly improving the output efficiency of the stratified clear water flow.

[0021] In a preferred example, the annular groove has a ring structure and smoothly transitions to the diversion annular cone surface to form a continuous flow path.

[0022] Specifically, this structure can prevent sand-laden fluid from forming vortices or stagnating in the transition zone, and the sand particles naturally slide into the settling tray along the annular groove under the action of gravity, effectively improving the settling efficiency.

[0023] In a preferred example, the sedimentation tray is detachably installed at the bottom of the sedimentation box and sealed to its surface.

[0024] Specifically, this structure allows operators to perform sand removal operations without disassembling the main valve body, enabling periodic maintenance; the sand settling tray can quickly remove accumulated sand, prevent flow channel blockage, and extend the service life of the equipment.

[0025] In a preferred example, a flow sensor is embedded in the surface of the cone guide seat. The signal output terminal of the flow sensor is connected to an electrical control module. The control module drives the servo motor to work, thereby automatically adjusting the blade deflection angle according to the flow velocity signal.

[0026] Specifically, the automatic control system achieves adaptive adjustment of swirl intensity, maintaining constant swirl intensity and stable separation efficiency under different flow conditions, reducing manual intervention and energy consumption.

[0027] The beneficial effects achieved by this invention are as follows: 1. In this invention, the adaptive control of the inlet vortex intensity is achieved by linking the blades in the flow guide assembly with the control servo motor. The flow guide angle can be automatically adjusted according to the flow rate change, so that the water flow entering the vortex guide assembly forms a stable vortex field, thereby significantly improving the water and sediment separation efficiency and maintaining the stable operation of the system under different working conditions.

[0028] 2. In this invention, the rotating cone inside the vortex diversion assembly rotates automatically under the action of fluid kinetic energy. Combined with the synergistic effect of the diversion blade, spiral blade and diversion ring, it realizes the spatial stratification of water flow and sand particles. The clean water is discharged through the core flow pipe, and the sand particles are guided into the sedimentation box along the sand discharge trough, which effectively avoids sand particles from entering the ball valve body and causing wear or jamming.

[0029] 3. In this invention, the sedimentation box, combined with the annular groove and the detachable sedimentation tray, constitutes a non-powered sedimentation system. The centrifugal force and gravity generated within the vortex diversion component are used to achieve natural stratification and sedimentation of sand particles. Automatic separation of sand and water and sand discharge can be completed without external drive or energy input. At the same time, the sedimentation tray can be directly disassembled for cleaning. The structure is simple and maintenance is convenient, ensuring that the ball valve maintains low energy consumption and high reliability during long-term operation. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0033] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0034] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a water-electric ball valve with a sand-clearing structure.

[0035] Combination Figures 1-9 As shown, the present invention provides a water and electricity ball valve with a sand-clearing structure, comprising: a ball valve body 100, a flow guiding component 200, a swirling flow guiding component 300, and a sand settling box 400 fixed on the outer periphery of the swirling flow guiding component 300.

[0036] The ball valve body 100 is an integral metal shell structure, with one end fixedly connected to the core flow tube 110 to provide a central flow path for clean water. The two ends of the vortex diversion assembly 300 are respectively connected to the flow guide assembly 200 and the ball valve body 100, forming a continuous inlet and outlet water channel, integrating water flow introduction, vortex, and separation functions. The flow guide assembly 200 includes a valve ring 210, a cone guide seat 220, and several blades 230 evenly distributed along the circumference. The blades 230 are rotatably mounted on the outer circumference of the valve ring 210 via shaft pins 231. Each blade 230 can be synchronously deflected under the drive of the control servo motor 211, and the vortex intensity of the introduced fluid can be adjusted by changing the blade 230 tilt angle. The control servo motor 211 is fixed to the valve ring 210 and drives each blade 230 to rotate synchronously via a crank rod 240 and a connecting rod 250. The vortex diversion assembly 300 includes a vortex tube 310 and a rotating cone 320 rotatably mounted inside it. A sand discharge groove 311 is formed on the surface of the vortex tube 310, and a bearing ring 312 is fixedly mounted inside it. One end of the rotating cone 320 slides against the bearing ring 312 to achieve low-friction rotation. A sedimentation box 400 is fixed to the outer periphery of the vortex diversion assembly 300 and contains a sedimentation tray 420 and a removable annular groove 410 for sedimentation and collection of sand particles.

[0037] The outer surface of the rotating cone 320 is provided with flow divider blades 321 and spiral blades 322, the number of which are the same and correspond one-to-one; a flow divider ring 323 is provided on the rotating cone 320, and a drainage groove hole 324 is formed between the spiral blades 322, and a core cylinder cavity 325 is formed on the inner side. One end of the core flow tube 110 extends coaxially into the core cylinder cavity 325 for discharging the central clear water.

[0038] This structure forms a continuous water flow path from the flow guiding component 200 → vortex diversion component 300 → sedimentation box 400 → core flow tube 110, realizing the integration of flow guiding, vortex diversion, separation and sediment discharge.

[0039] In this embodiment, the blade 230 is arranged radially along the outer periphery of the cone guide 220 and is located between the cone guide 220 and the valve ring 210.

[0040] The surface of the cone guide seat 220 is a cone structure. When external water flows into the guide assembly 200, the fluid first contacts the surface of the cone guide seat 220, generating circumferential diffusion and forming a radial dispersion flow. Each blade 230 guides the water flow in a deflected state, causing the fluid to enter the downstream vortex diversion assembly 300 along a specific vortex direction. Through this guide structure, the water flow entering the vortex diversion assembly can acquire initial angular momentum, thereby enhancing vortex stability and sand-water stratification.

[0041] In this embodiment, a crankshaft 240 is fixedly connected to the surface of each pin 231, and a connecting rod 250 is movably connected between adjacent crankshafts 240, forming a ring-shaped linkage mechanism. The output shaft of the control servo motor 211 is fixedly connected to the pin 231 of one of the blades 230. When the servo motor rotates, it drives the blade 230 to deflect, and simultaneously, the synchronous deflection of all blades 230 is achieved through the transmission of the crankshaft 240 and the connecting rod 250. The connection point between the crankshaft 240 and the connecting rod 250 is offset from the axis of the pin 231 to obtain an angular displacement amplification effect, so that a small-angle motor action can achieve a large-angle blade deflection.

[0042] This mechanism ensures that all blades in the guide assembly have a consistent 230° deflection angle, maintaining swirl symmetry and stability.

[0043] In this embodiment, the rotating cone 320 is a hollow cone with several flow-diverting blades 321 and helical blades 322 distributed on its surface. The number of flow-diverting blades 321 and helical blades 322 are equal and arranged in a one-to-one correspondence. The flow-diverting blades 321 are distributed axially to uniformly disperse the introduced water flow; the helical blades 322 extend in the tangential helical direction to apply a swirling shear force to the fluid, causing the fluid to accelerate along the helical path. The rotating cone 320 can rotate freely under the action of the fluid tangential force, thereby enhancing the swirling flow guidance effect and achieving self-excited swirling flow enhancement.

[0044] This structure enhances swirling flow through active swirling, achieving swirling boost without external energy consumption and significantly improving sand-water separation efficiency.

[0045] In this embodiment, the diversion ring 323 is disposed on the outer surface of the rotating cone 320, and its surface has a conical structure. The conical surface slides and fits against the inner wall of the vortex tube 310 and is located in the same vertical plane. The diversion ring 323 is used to achieve water and sand stratification in the vortex field: the central clear water enters the core cylinder cavity 325 through the drainage groove hole 324 on the inner side of the diversion ring 323, and is introduced into the ball valve body 100 through the core tube 110; The sediment-laden water in the outer ring flows along the inner wall of the vortex tube 310 under the guidance of the cone surface of the diversion ring 323 and enters the sediment discharge trough 311.

[0046] During this process, a continuous flow channel is formed between the vortex tube 310 and the flow divider ring 323, allowing the sand-laden fluid to smoothly transition to the sedimentation box 400. This structure achieves efficient water-sand spatial separation, preventing sand particles from entering the valve body with the mainstream.

[0047] In this embodiment, the core flow tube 110 and the rotating cone 320 are arranged coaxially, with one end of the core flow tube 110 extending into the core cavity 325 inside the rotating cone 320. This arrangement ensures that the clean water forms an independent drainage channel at the center of the swirling field, effectively isolating sediment. Under centrifugal stratification, the clean water automatically converges to the central area and is directly output to the downstream passage of the ball valve body 100 through the core flow tube 110, achieving efficient clean water output and valve body protection.

[0048] In this embodiment, the annular groove 410 is located at the bottom of the sedimentation box 400, forming a ring structure and smoothly transitioning to the conical surface of the diversion ring 323. When the sand-laden water flow is introduced into the sedimentation box 400 through the outer ring of the vortex diversion component 300, the sand particles slide and settle along the inclined surface of the annular groove 410 under the action of gravity and centrifugal force. The smooth transition structure reduces the impact resistance of the sand particles, ensures continuous fluid flow, and avoids stagnation in the transition zone. This structure significantly improves the sand particle settling efficiency and reduces flow channel wear.

[0049] In this embodiment, the sedimentation tray 420 is detachably installed at the bottom of the sedimentation box 400 and is sealed to the lower end face of the sedimentation box 400. During operation, sand-laden water flows through the sand discharge channel 311 into the sedimentation box 400. Due to the reduced flow velocity and gravity, the sand particles settle to the bottom of the sedimentation tray 420 and accumulate. When the sand particles accumulate to a certain amount, they can be cleaned by opening the bottom interface of the sedimentation box 400 or by directly disassembling the sedimentation tray 420. After cleaning, it can be reinstalled to continue operation without replacing the main components.

[0050] This design facilitates maintenance and prevents long-term sand accumulation from causing channel blockage and structural wear.

[0051] In this embodiment, a flow sensor is embedded in the surface of the guide seat 220, which detects the water flow velocity and pressure parameters in real time. The flow sensor signal is output to the electrical control module, which automatically adjusts the rotation angle of the control servo motor 211 according to the change in flow velocity, thereby changing the tilt angle of the blade 230.

[0052] When the flow velocity increases, the control servo 211 drives the blade 230 to reduce the tilt angle, thereby reducing the swirling intensity; when the flow velocity decreases, the blade 230 tilt angle increases to maintain a stable swirling effect.

[0053] This closed-loop feedback control system enables adaptive control of the vortex intensity, ensuring that the entire system maintains efficient diversion and sand removal performance under different water pressure and flow conditions.

[0054] Working principle and usage process of this invention: This invention proposes a hydroelectric ball valve with a sand-clearing structure. Through the cooperation of a flow guiding component 200, a vortex diversion component 300, and a sand settling box 400, it achieves a comprehensive function of directional water flow introduction, vortex formation, and automatic sand separation. Its operating principle is as follows: When external water flows into the first flow guide component 200, the water flows through the cone guide seat 220 and forms a radial dispersion. The cone guide seat 220 has a cone-shaped structure on its surface, which makes the fluid generate a uniformly distributed annular flow in the entry area.

[0055] Multiple blades 230 are arranged radially around the outer periphery of the conical guide seat 220 and can synchronously deflect around the pivot pin 231 under the drive of the control servo motor 211. The servo motor 211 drives all blades 230 to synchronously adjust their tilt angle through a linkage mechanism formed by the crank rod 240 and connecting rod 250, thereby changing the fluid inflow angle and swirling intensity. When the control module detects a change in water flow velocity based on the output signal of the flow sensor, it automatically adjusts the deflection angle of the blades 230 to maintain the swirling intensity at the optimal state, achieving adaptive fluid regulation.

[0056] After being deflected and guided by the blades 230, the water flows into the swirling flow guide assembly 300 along the swirling direction, gradually forming a strong swirling field within the swirling tube 310. At this time, the water flow generates centrifugal force due to rotation and simultaneously drives the rotating cone 320 to rotate. The centrifugal effect causes larger sand and gravel particles to be thrown towards the tube wall, while the clear water remains in the central flow zone.

[0057] The rotating cone 320 in the swirl guiding assembly 300 is located inside the swirl tube 310 and is supported by a bearing ring 312 to achieve low-friction rotation. The outer surface of the rotating cone 320 has several flow divider blades 321 and helical blades 322, with a one-to-one correspondence between the two. After the water flow is further dispersed by the flow divider blades 321, it forms a helical flow along the helical blades 322, causing the rotating cone 320 to rotate under the action of the fluid tangential force, further improving the stability of the centrifugal swirl.

[0058] The flow-dividing ring 323 on the surface of the rotating cone 320 plays a role in stratifying and guiding the flow. Its conical surface separates the central water flow in the vortex from the water flow with sand particles in the outer ring. The central clean water enters one side of the rotating cone 320 through the drainage groove hole 324 and enters the core cylinder cavity 325. It is collected by water pressure and output to the ball valve body 100 through the core flow pipe 110, thus isolating the ball valve body 100 from mud and sand impurities. The outer ring fluid in the sand-laden area moves close to the inner wall of the vortex tube 310 under the guidance of the conical surface of the diversion ring 323, and is eventually introduced into the sand discharge trough 311. As a continuous annular flow field is formed between the rotating cone 320 and the vortex tube 310, the sand particles gradually gather outward under the action of centrifugal force, and the water and sand are initially separated.

[0059] The sediment-laden water flows along the sediment discharge channel 311 into the inner side of the annular channel 410, which is located inside the sedimentation box 400 and arranged in a ring. The annular channel 410 and the conical surface of the diversion ring 323 maintain a smooth transition, allowing the sediment to flow continuously and without obstruction. When the sand particles are carried into the annular channel 410, they are quickly deposited into the sedimentation tray 420 at the bottom area due to the sudden drop in velocity and gravity.

[0060] The deposited sand particles are concentrated in the settling tray 420, which is a detachable structure for easy periodic cleaning. When sand needs to be discharged, the bottom interface of the settling box 400 can be opened or the settling tray 420 can be disassembled. The accumulated sand and gravel inside can be cleaned by manually disassembling the settling tray 420 periodically.

[0061] In continuous operation, water enters through the guide component 200 and forms a spiral flow field through the vortex diversion component 300, completing the spatial separation of water and sand. The rotating cone 320 in the vortex diversion component 300 continuously rotates under the drive of fluid kinetic energy, maintaining a highly efficient vortex state and preventing sedimentary sand particles from accumulating in the mainstream area.

[0062] Meanwhile, the control servo motor 211, under the action of the electrical control module, automatically adjusts the blade angle 230 according to the real-time flow signal, so that the swirling intensity and separation efficiency remain stable.

[0063] The entire system can complete sand-water separation, automatic sedimentation, and directional sand discharge without external power, ensuring smooth water flow during long-term operation of the ball valve and avoiding jamming and wear caused by sand accumulation.
