Description

Technical Field

[0001] This invention relates to the field of control valve technology, specifically to a control valve and method for a concrete conveying pipeline in a basement garage. Background Technology

[0002] Concrete pumping technology, as one of the core processes in modern construction, plays an irreplaceable role in high-rise buildings, large-scale infrastructure, and underground engineering. With the deepening of urbanization and the increasing scarcity of land resources in my country, the scale of underground space development and utilization is constantly expanding, and basement garages have become a standard feature of modern buildings. Against this backdrop, the technical performance and reliability of concrete delivery pipeline control systems, especially the control valves as core components, directly determine the quality and efficiency of underground engineering construction.

[0003] For example, patent document CN217539746U relates to a control valve for a concrete pump truck's delivery pipe, belonging to the field of valve device technology. The key technical point is that it includes a housing and a sealing assembly disposed inside the housing. The upper end of the housing has an inlet, and the lower end has an outlet. The housing contains a sealing chamber and a receiving chamber. The sealing chamber is located above and communicates with the receiving chamber. A flushing connector is connected to the receiving chamber, and a switching valve is disposed between the flushing connector and the housing. This patent document facilitates flushing the inside of the control valve and is less likely to cause blockage of the valve body.

[0004] While existing flushing joint solutions can clear blockages in control valves by flushing with water, this temporary measure violates fundamental principles of concrete quality control. The additional water introduced during flushing inevitably mixes with the working concrete, altering the strictly controlled water-cement ratio parameter in the original mix design. According to basic concrete materials science, the water-cement ratio is a key factor determining concrete strength and durability; any undesigned change in the water-cement ratio will directly weaken the mechanical properties and long-term stability of the concrete. In engineering environments like basement garages, where structural integrity and durability are paramount, uneven reduction in localized concrete strength can lead to abnormal stress distribution, accelerated structural aging, and even compromised structural safety. Therefore, this application proposes a control valve and method for concrete delivery pipelines in basement garages. Summary of the Invention

[0005] The purpose of this invention is to provide a control valve and method for concrete delivery pipelines in basement garages, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a control valve for a concrete conveying pipeline in a basement garage, comprising a valve box and a flow channel formed therein, a valve core plate for sealing the flow channel, and further comprising: The self-adaptive anti-clogging system includes a rotatable sleeve rotatably disposed at the inlet of the flow channel, and a drive assembly for driving the rotatable sleeve to reciprocate about its axis. It also includes a radially adaptive element, which includes a plurality of radially expandable and contractile inclined flexible liners disposed within the wall of the rotatable sleeve. Before the valve core plate is opened, the drive assembly can drive the rotatable sleeve to reciprocate to loosen the concrete at its front end, while the plurality of inclined flexible liners can be controlled to retract radially. The segregated water recycling system includes a segregated water tank located inside a valve box, which is connected to a segregated water channel for collecting water separated from concrete. It also includes a return trough, one end of which is connected to the segregated water tank via a liquid chamber, and the other end is provided with a return nozzle, the outlet of which faces the inlet of the flow channel. It also includes a diaphragm pump for conveying the segregated water in the segregated water tank, and a piston plate located on the return trough, with a pressure control component inside the piston plate.

[0007] Preferably, the drive assembly includes an air chamber shell fixedly connected to the outer surface of the rotatable sleeve, a plurality of active inclined blocks are uniformly fixedly connected to the outer surface of the air chamber shell, a connecting rod is slidably connected inside the valve box, and a pressure bead adapted to the active inclined block is fixedly connected to the top of the connecting rod, and an arc-shaped rubber diaphragm is fixedly connected inside the liquid chamber, and the arc-shaped rubber diaphragm is connected to the plurality of connecting rods.

[0008] Preferably, it also includes multiple pressure cylinders fixedly connected inside the air chamber housing, and a hydraulic rod is slidably connected inside the pressure cylinder. A ball bearing is rotatably connected to one end of the hydraulic rod away from its piston end. Multiple pressure control blocks for the ball bearing to slide are fixedly connected inside the valve box. One end of the pressure cylinder has a perforation for oil to pass through.

[0009] Preferably, the pressure control assembly includes a fine-hole pipe fixedly connected to one end of the piston plate, the fine-hole pipe extending into the return groove, and having fine holes for liquid to pass through inside the fine-hole pipe. A ball valve body is rotatably connected inside the fine holes, and the assembly also includes a release mechanism that controls the opening and closing of the ball valve body according to hydraulic pressure.

[0010] Preferably, the release mechanism includes a push rod fixedly connected inside the return groove, a connecting crank rotatably connected to the piston plate passing through the inside of the ball valve body, a ball adapted to the connecting crank being rotatably connected to one end of the push rod, and a torsion spring for self-reset being sleeved on the outer surface of the connecting crank.

[0011] Preferably, a storage spring is fixedly connected inside the reflux trough, and one end of the storage spring is fixedly connected to the piston plate.

[0012] Preferably, the inclined flexible liner is a hollow bladder made of elastic material, which is filled with hydraulic oil, and the expansion and contraction of the bladder are achieved by the change of oil pressure.

[0013] Preferably, a hydraulic control component for driving the valve core plate to move is fixedly connected to the top of the valve box.

[0014] Preferably, one end of the valve box is fixedly connected to a flange interface, and the other end of the valve box is fixedly connected to a flange outlet, and the two ends of the flow channel are respectively connected to the flange interface and the flange outlet.

[0015] The present invention also provides a method for controlling concrete delivery pipelines in basement garages, comprising the following steps: S1. Install the valve box in the concrete pipe and control the opening and closing of the flow channel by controlling the raising and lowering of the valve core plate; S2. When the valve core plate is closed, the concrete is blocked in the upstream area of ​​the flow channel. As the standing time increases, the concrete gradually exudes water, and the exuded water is collected into the separation water tank through the separation water channel. S3. By operating the self-adaptive anti-blocking system, the rotatable sleeve can be rotated back and forth to mechanically disturb the stagnant concrete, while multiple inclined flexible inner linings can be controlled to radially shrink and make way. S4. Simultaneously, when the water pressure in the liquid chamber increases due to the operation of the segregated water recycling system, it will push the piston plate to move. Subsequently, the segregated water will be discharged through the return nozzle and remixed with the concrete.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up an optimized streamlined flow channel, concrete can flow smoothly under gravity, reducing resistance loss. The precise cooperation between the hydraulic control components and the valve core plate ensures reliable sealing of the flow channel. Its fast response time and high positioning accuracy effectively avoid the lag and inaccuracy of traditional mechanical drives, ensuring the continuity and controllability of the concrete delivery process. The self-adaptive anti-clogging system achieves the physical anti-clogging principle of simultaneous stirring and clearance through the synergistic working mechanism of the rotatable sleeve and the inclined flexible liner. Before the valve restarts, the rotatable sleeve reciprocates, generating a high-strength shearing effect on the static concrete, breaking the static friction network and bridging structure between aggregates, and reducing the yield stress of the concrete. Simultaneously, the inclined flexible liner contracts radially by 3-5mm under controlled conditions, creating temporary flow space for the loosened concrete particles. This keeps the restart pressure peak within a reasonable multiple of the normal operating pressure, fundamentally solving the risk of pipe blockage caused by excessive starting torque when traditional valves open. The active inclined block on the surface of the air chamber sleeve and the pressure ball at the top of the connecting rod form a precise mechanical conversion mechanism, achieving efficient conversion of water pressure to mechanical motion through the deformation of the arc-shaped rubber diaphragm. The cooperation between the pressure-controlling inclined block and the sliding ball converts the rotational motion of the rotatable sleeve into the linear motion of the hydraulic rod within the pressure cylinder. By controlling the flow of hydraulic oil through perforations, precise radial contraction of the inclined flexible liner is achieved. This multi-linkage mechanism significantly improves energy conversion efficiency, far exceeding that of traditional single-function mechanisms.

[0017] 2. As the core power unit of the system, the diaphragm pump not only draws segregated water from the bottom of the segregated water tank, but also delivers gas when the segregated water is insufficient, driving the rotation of the rotatable sleeve, thus achieving flexibility and reliability in energy use. When the water pressure in the liquid chamber increases, it pushes the arc-shaped rubber diaphragm to deform, driving the rotatable sleeve to rotate and agitate the concrete through the sliding of the connecting rod and pressure balls on the active inclined block; on the other hand, it pushes the piston plate to move, triggering the pressure control component to work, allowing the segregated water to be re-injected into the concrete. This dual-use mechanism transforms the originally wasteful segregated water into the driving force of the anti-clogging system and a concrete performance restorer. The pressure control component achieves precise pressure control and efficient release through the precise cooperation of the fine-hole pipe, ball valve body, and release mechanism. When the water pressure in the liquid chamber increases, the piston plate moves forward to overcome the resistance of the storage spring, and the fine-hole pipe is inserted into the return groove; when the pressure continues to increase, the push rod pushes the connecting crank to rotate through the ball, overcoming the resistance of the torsion spring and opening the ball valve body. The moment the ball valve opens, the pressurized and separated water passes through the fine-hole pipe at high speed, forming a brief but high-intensity pulse water flow. This pulse effect is more effective than continuous low-flow spraying in breaking the initial gel structure of the concrete surface. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 - Figure 10This invention provides a technical solution: a control valve for a concrete conveying pipeline in a basement garage, comprising a valve box 100 and a flow channel 105 formed therein, a valve core plate 104 for sealing the flow channel 105, a hydraulic control component 103 for driving the valve core plate 104 to move fixedly connected to the top of the valve box 100, a flange interface 101 fixedly connected to one end of the valve box 100, a flange outlet 102 fixedly connected to the other end of the valve box 100, and the two ends of the flow channel 105 being connected to the flange interface 101 and the flange outlet 102 respectively. The valve is connected to the flow channel 102. The flow channel 105 allows concrete to flow smoothly by gravity. The hydraulic control component 103, in cooperation with the valve core plate 104, can effectively close the flow channel 105 to control the pipeline transportation. The hydraulic control component 103 is the driving device of the entire valve and the core actuator for its automated control. It receives signals from the control system and generates linear thrust or lifting force, thereby driving the valve core plate 104 to move vertically up and down, thus controlling the opening and closing of the flow channel 105.

[0022] By designing an optimized streamlined flow channel 105, concrete can flow smoothly under gravity, reducing resistance loss by up to 35%. The precise fit between the hydraulic control component 103 and the valve core plate 104 ensures reliable closure of the flow channel 105. As the core actuator of the entire valve, the hydraulic control component 103 receives signals from the control system, generates precise linear thrust, and drives the valve core plate 104 to move vertically up and down, thus controlling the opening and closing of the flow channel 105. Its response time is less than 0.5 seconds, and its positioning accuracy reaches ±0.1mm, effectively avoiding the lag and inaccuracy of traditional mechanical drives. The key innovation of this invention lies in the self-adaptive anti-clogging system, which includes a rotatable sleeve 200 rotatably disposed at the inlet of the flow channel 105, a drive assembly for driving the rotatable sleeve 200 to reciprocate about its axis, and a radially adaptive component comprising a plurality of radially retractable inclined flexible liners 201 disposed within the wall of the rotatable sleeve 200. Before the valve core plate 104 is opened, the drive assembly can drive the rotatable sleeve 200 to reciprocate to loosen the concrete at its front end, while the plurality of inclined flexible liners 201 can be controlled to radially contract. The reciprocating rotation of 200 generates a strong shear force on the static concrete, breaking the static friction and bridging structure between aggregates. The synchronous contraction of the inclined flexible inner liner 201 creates a temporary, additional space on the inner wall of the sleeve, providing room for the loosened concrete particles to move and greatly reducing the starting resistance. This synergistic mechanism of stirring and yielding can extremely effectively restore the concrete that has become hardened at the valve inlet to a flowable, loose state, fundamentally avoiding the risk of pipe blockage caused by excessive starting torque when the valve core is opened.

[0023] Simultaneously, before the valve core plate 104 is opened, the drive assembly drives the rotatable sleeve 200 to reciprocate within ±15°~30°, generating a high-intensity shearing effect on the static concrete, effectively breaking the static friction network and bridging structure formed between the aggregates, reducing the yield stress of the concrete, and restoring its fluid nature.

[0024] Space compensation design: The inclined flexible liner 201 shrinks radially by 3-5mm under controlled conditions, creating temporary flow space for the loosened concrete particles and significantly reducing starting resistance. This synergistic mechanism of stirring and yielding simultaneously solves the risk of pipe blockage caused by excessive starting torque at the moment of valve opening from a physical source, and controls the peak restart pressure to within 1.2 times the normal operating pressure.

[0025] Anti-adhesion surface renewal: During the rotation of the rotatable sleeve 200, the surface of the inclined flexible inner lining 201 is constantly renewed, avoiding the adhesion effect caused by prolonged contact between concrete and the fixed surface. The surface adhesion is reduced by more than 70%, fundamentally preventing blockage caused by local initial setting.

[0026] Meanwhile, when the concrete flows smoothly, the inclined flexible liner 201 can guide the concrete to pass through smoothly.

[0027] Furthermore, the drive assembly includes an air chamber housing 202 fixedly connected to the outer surface of the rotatable sleeve 200. Multiple active inclined blocks 203 are uniformly fixedly connected to the outer surface of the air chamber housing 202. A connecting rod 204 is slidably connected inside the valve box 100. A pressure bead 206 adapted to the active inclined block 203 is fixedly connected to the top of the connecting rod 204. An arc-shaped rubber diaphragm 205 is fixedly connected inside the liquid chamber 302. The arc-shaped rubber diaphragm 205 is connected to multiple connecting rods 204. A spring 207 for self-reset is sleeved on the outer surface of the connecting rod 204.

[0028] Furthermore, it also includes multiple pressure cylinders 208 fixedly connected inside the air chamber housing 202, and a hydraulic rod 209 is slidably connected inside the pressure cylinder 208. A ball bearing 210 is rotatably connected to one end of the hydraulic rod 209 away from its piston end. Multiple pressure control blocks 212 for the ball bearing 210 to slide are fixedly connected inside the valve box 100. One end of the pressure cylinder 208 is provided with a perforation 211 for oil to pass through.

[0029] The inclined flexible liner 201 is a hollow bladder made of elastic material, filled with hydraulic oil. The bladder expands and contracts through changes in oil pressure. A shared hydraulic system ensures that all inclined flexible liners 201 experience essentially the same oil pressure, achieving uniform and synchronized contraction. This avoids new flow resistance caused by uneven contraction. Furthermore, this contraction is not a forced extrusion of space into the concrete, but rather a space created during rotational loosening. This significantly reduces the adhesion between the concrete and the inner wall of the sleeve, as well as translational frictional resistance, making the loosening effect much more efficient.

[0030] Specifically, before opening the valve core plate 104, water is drawn from the separation tank 300 by the diaphragm pump 301 and transported to the liquid chamber 302. At this time, the water inside the liquid chamber 302 increases and gradually expands, pushing the arc-shaped rubber diaphragm 205 to deform. The deformation of the arc-shaped rubber diaphragm 205 will pull the connecting rod 204 to move and push the pressure ball 206 to slide on the inclined surface of the active inclined block 203, thereby driving the rotatable sleeve 200 to rotate and tamp the concrete, making it soft. At the same time, when the rotatable sleeve 200 rotates, the sliding ball 210 will roll on the inclined surface of the pressure control inclined block 212, thereby driving the piston end of the pressure rod 209 to move in the pressure cylinder 208, causing the oil in the air chamber sleeve 202 to flow back into the pressure cylinder 208, causing the multiple inclined flexible inner linings 201 to shrink under the support of the oil, providing more space for the concrete and preventing it from clogging.

[0031] In summary, by setting an optimized streamlined flow channel 105, concrete can flow smoothly under gravity, reducing resistance loss. The precise cooperation between the hydraulic control component 103 and the valve core plate 104 ensures reliable sealing of the flow channel 105. Its fast response time and high positioning accuracy effectively avoid the lag and inaccuracy of traditional mechanical drives, ensuring the continuity and controllability of the concrete conveying process. The self-adaptive anti-clogging system, through the collaborative working mechanism of the rotatable sleeve 200 and the inclined flexible liner 201, achieves the physical anti-clogging principle of simultaneous stirring and clearance. Before the valve restarts, the rotatable sleeve 200 reciprocates, generating high-strength shearing action on the static concrete, breaking the static friction network and bridging structure between aggregates, thus reducing the yield stress of the concrete. Simultaneously, the inclined liner... The flexible liner 201 contracts radially by 3-5mm under controlled conditions, creating temporary flow space for the loosened concrete particles and keeping the restart pressure peak within a reasonable multiple of the normal operating pressure. This fundamentally solves the risk of pipe blockage caused by excessive starting torque when opening traditional valves. The active inclined block 203 on the surface of the air chamber sleeve 202 and the pressure ball 206 at the top of the connecting rod 204 form a precise mechanical conversion mechanism, achieving efficient conversion of water pressure to mechanical motion through the deformation of the arc-shaped rubber diaphragm 205. The cooperation between the pressure control inclined block 212 and the sliding ball 210 converts the rotational motion of the rotatable sleeve 200 into the linear motion of the hydraulic rod 209 within the pressure cylinder 208. The flow of hydraulic oil is regulated through the perforation 211, achieving precise radial contraction of the inclined flexible liner 201. This multi-linkage mechanism significantly improves energy conversion efficiency, far exceeding that of traditional single-function mechanisms.

[0032] Example 2: Please refer to Figure 1 - Figure 10This invention also provides a technical solution for collecting naturally segregated water from concrete and reusing it to improve the workability of that portion of the concrete. The technical solution differs from Embodiment 1 as follows: a control valve for a concrete delivery pipeline in a basement garage, further comprising a segregated water recycling system, including a segregated water tank 300 located within a valve box 100, and connected to segregated water channels 306 for collecting water segregated from the concrete. Eight to twelve small segregated water channels 306, each with a diameter of 3 to 5 mm, communicate with the space above the valve core plate 104. These segregated water channels 306 are designed as conical filter structures with a mesh size of 0.5 to 1.0 mm. The system, measuring 2mm in diameter, effectively separates water while preventing fine aggregates larger than 2mm from entering, achieving a water collection efficiency of over 98% while avoiding system blockage risks. It also includes a reflux trough 303, one end of which is connected to the separation tank 300 via a liquid chamber 302, and the other end has a reflux nozzle 304, the outlet of which faces the inlet of the flow channel 105. A diaphragm pump 301 is also included, used to transport the separated water from the separation tank 300. One end of the diaphragm pump 301 is connected to a hose placed at the bottom of the separation tank 300, and a piston plate 307 is installed on the reflux trough 303, with a pressure control component inside the piston plate 307. The top of the segregation tank 300 is connected to the space above the valve core plate 104 via several small segregation channels 306. The segregation channels 306 can be designed as a filter screen to prevent large aggregate particles from entering. Before the valve core plate 104 is opened, the diaphragm pump 301 starts, drawing water from the concrete in the segregation tank 300 and transporting it to the liquid chamber 302. The water pressure inside the liquid chamber 302 increases, causing the arc-shaped rubber diaphragm 205 to deform. This deformation, through a linkage mechanism, pulls the connecting rod 204 to move, causing the pressure beads 206 to slide on the inclined surface of the active inclined block 203, driving the rotatable sleeve 200 to rotate and agitate the concrete. At the same time, the rotating sleeve 200 rotates and drives the sliding ball 210 to roll on the inclined surface of the pressure control block 212, driving the hydraulic rod 209 to move inside the pressure cylinder 208, so that the hydraulic oil flows back from the inclined flexible liner 201 through the perforation 211, causing the inclined flexible liner 201 to contract radially, providing additional flow space for the concrete and effectively preventing blockage.

[0033] Furthermore, the pressure control assembly includes a fine-hole pipe 401 fixedly connected to one end of the piston plate 307. The fine-hole pipe 401 can extend into the return groove 303, and a fine hole for liquid to pass through is opened inside the fine-hole pipe 401. A ball valve body 400 is rotatably connected inside the fine hole. It also includes a release mechanism that controls the opening and closing of the ball valve body 400 according to hydraulic pressure.

[0034] Furthermore, the release mechanism includes a push rod 404 fixedly connected inside the return groove 303, a connecting crank 402 rotatably connected to the piston plate 307 passing through the inside of the ball valve body 400, a ball 405 adapted to the connecting crank 402 being rotatably connected to one end of the push rod 404, and a torsion spring 403 for self-reset being sleeved on the outer surface of the connecting crank 402.

[0035] As the water pressure in the liquid chamber 302 gradually increases, it pushes the piston plate 307 to move forward against the resistance of the storage spring 305, and the fine-hole pipe 401 is inserted into the predetermined position of the return groove 303. When the pressure continues to increase, the push rod 404 is connected to the crank 402 through the ball bearing 405, causing it to rotate against the torque of the torsion spring 403, driving the ball valve body 400 from the sealed position to the open position, forming a precise pressure-opening correspondence.

[0036] Rapid pulse release: At the moment the ball valve body 400 opens, the pressurized segregated water flows through the fine-hole pipe 401 at a high speed, forming a brief but high-intensity pulse water flow. This pulse effect is more effective than continuous low-flow spraying in breaking the initial gel structure of the concrete surface, thus improving the loosening efficiency.

[0037] Automatic reset protection: When the pressure is released, the accumulator spring 305 pushes the piston plate 307 to reset, and at the same time the torsion spring 403 causes the connecting crank 402 to rotate, and the ball valve body 400 re-seales. The entire reset process is completed within 0.5 seconds, preventing air from entering the system or residual moisture from leaking, and preparing for the next operation.

[0038] Wear compensation mechanism: The fit between the ball bearing 405 and the connecting crank 402 is adjustable. When wear gaps occur after long-term use, the gaps can be compensated by the fine-tuning mechanism to maintain the accuracy of the action and extend the life of the system.

[0039] The diaphragm pump 301 is provided to supply gas to the rotatable sleeve 200 for rotation when the separation water in the separation water tank 300 is insufficient.

[0040] The reflux groove 303 is internally fixedly connected to a storage spring 305, one end of which is fixedly connected to a piston plate 307.

[0041] Specifically, when the valve box 100 is closed, the concrete will be blocked by the valve core plate 104 and located at the upper end of the flow channel 105. Due to the long-term static state of the concrete, it will undergo segregation. At this time, the segregated water will flow into the segregation tank 300 through the segregation channel 306 for internal storage. Since the concrete has been stored for too long, it will dry out and easily block the flow channel 105. At the same time, when the water pressure in the liquid chamber 302 increases, it will push the piston plate 307 to move, thereby allowing the fine hole pipe 401 to be inserted into the return groove 303. Then, the ball 405 abuts against the connecting crank 402 to make it rotate, thereby changing the position of the ball valve body 400 to allow water to pass through. Then, the water will pass through the fine hole pipe 401 and then be discharged through the return nozzle 304 to remix with the concrete.

[0042] It is worth mentioning that the hydraulic pressure is released rapidly the moment the ball valve body 400 is opened, allowing the segregated water to be discharged through the return nozzle 304 and mixed with the concrete. At the same time, the piston plate 307 will reset under low air pressure, causing the ball valve body 400 to close again. Meanwhile, the hydraulic pressure in the liquid chamber 302 decreases, causing the connecting rod 204 to reset and move downward, while driving the rotatable sleeve 200 to rotate and reset, forming an axial reciprocating rotation. At the same time, the multiple inclined flexible liners 201 are also in a dynamic expansion and contraction state, improving the anti-clogging effect.

[0043] In summary, the diaphragm pump 301, as the core power unit of the system, can not only draw segregated water from the bottom of the segregated water tank 300, but also deliver gas when the segregated water is insufficient to drive the rotation of the rotatable sleeve 200, thus achieving flexibility and reliability in energy use. When the water pressure in the liquid chamber 302 increases, it pushes the arc-shaped rubber diaphragm 205 to deform, and through the sliding of the connecting rod 204 and the pressure ball 206 on the active inclined block 203, it drives the rotatable sleeve 200 to rotate and agitate the concrete; on the other hand, it pushes the piston plate 307 to move, triggering the pressure control component to work, so that the segregated water is re-injected into the concrete. This dual-use mechanism transforms the originally wasteful segregated water into the driving force of the anti-clogging system and the concrete performance restorer. The pressure control component, through the precise cooperation of the fine-hole pipe 401, the ball valve body 400 and the release mechanism, achieves precise pressure control and efficient release. As the water pressure in the liquid chamber 302 increases, the piston plate 307 moves forward against the resistance of the storage spring 305, and the fine-hole pipe 401 is inserted into the return groove 303. When the pressure continues to increase, the push rod 404 pushes the connecting crank 402 to rotate through the ball bearing 405, overcoming the resistance of the torsion spring 403 and opening the ball valve body 400. At the moment the ball valve body 400 opens, the pressurized and separated water passes through the fine-hole pipe 401 at high speed, forming a brief but high-intensity pulse water flow. This pulse effect is more effective than continuous low-flow spraying in breaking the initial gel structure of the concrete surface.

[0044] Example 3: Please refer to Figure 1 - Figure 10The present invention also provides a technical solution, which differs from the technical solution of Embodiment 1 as follows: a method for controlling concrete conveying pipelines in basement garages, comprising the following steps: S1. Install the valve box 100 in the concrete pipe, wherein the flange interface 101 is the feed pipe and the flange outlet 102 is the discharge pipe. The valve core plate 104 can be raised and lowered by operating the hydraulic control component 103 to realize the opening and closing of the flow channel 105. S2. When the valve box 100 is closed, the concrete will be blocked by the valve core plate 104 and located at the upper end of the flow channel 105. Due to the long-term static state of the concrete, it will segregate. At this time, the segregated water will flow into the segregation tank 300 through the segregation channel 306 for storage. Since the concrete will dry out and easily block the flow channel 105 due to the long storage time at this time. S3. Before opening the valve core plate 104, water is drawn from the separation water tank 300 by the diaphragm pump 301 and transported to the liquid chamber 302. At this time, the water in the liquid chamber 302 increases and gradually expands, pushing the arc-shaped rubber diaphragm 205 to deform. The deformation of the arc-shaped rubber diaphragm 205 will pull the connecting rod 204 to move and push the pressure ball 206 to slide on the inclined surface of the active inclined block 203, thereby driving the rotatable sleeve 200 to rotate and tamp the concrete, making it soft. At the same time, when the rotatable sleeve 200 rotates, the sliding ball 210 will roll on the inclined surface of the pressure control inclined block 212, thereby driving the piston end of the pressure rod 209 to move in the pressure cylinder 208, so that the oil in the air chamber sleeve 202 flows back to the pressure cylinder 208, and the multiple inclined flexible inner linings 201 are supported by the oil and shrink, providing more space for the concrete and preventing it from clogging. S4. Simultaneously, when the water pressure in the liquid chamber 302 increases, it will push the piston plate 307 to move, thereby allowing the fine hole pipe 401 to be inserted into the return groove 303. Then, the ball 405 abuts against the connecting crank 402 to make it rotate, thereby changing the position of the ball valve body 400 to allow water to pass through. Then, the water will pass through the fine hole pipe 401 and then be discharged through the return nozzle 304 to be remixed with the concrete.
