Description

Technical Field

[0001] This invention relates to the field of control valve technology, specifically a self-closing control valve with pressure-sensing regulation function. Background Technology

[0002] In fluid transport systems, regulating valves are key components for controlling fluid flow and pressure, and their performance directly affects the stability and reliability of the system.

[0003] Existing self-closing control valves present several unresolved problems in practical applications. Firstly, most control valves lack precise pressure-sensing mechanisms, making it difficult to automatically adjust their opening based on real-time pressure changes within the pipeline. When system pressure fluctuates, this can easily lead to unstable fluid flow, triggering a series of problems. Secondly, air bubbles are easily generated during fluid transport, affecting both transport efficiency and stability. Furthermore, existing control valves are inadequate in energy utilization; the kinetic energy generated by fluid flow is not effectively recovered and utilized, resulting in energy waste. Summary of the Invention

[0004] The purpose of this invention is to provide a self-closing regulating valve with pressure-sensing regulation function to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A self-closing regulating valve with pressure-sensing regulation function includes an electric valve, an inlet pipe, an outlet pipe, a turbine generator, a defoaming device, a pressure-sensing device, and a regulating device. The electric valve is connected to the inlet pipe and the outlet pipe. The turbine generator is placed inside the outlet pipe and is securely connected to the outlet pipe. The defoaming device is connected to the outlet pipe. The pressure-sensing device is placed inside the outlet pipe and is securely connected to the outlet pipe. The regulating device is placed inside the outlet pipe and is connected to the outlet pipe.

[0007] The electric valve serves as the primary mounting base for installing other components. When the electric valve opens, water flows sequentially through the inlet pipe, electric valve, outlet pipe, turbine generator, defoaming device, pressure sensing device, and regulating device, before exiting from the outlet pipe. As the water flows through the turbine generator, it drives the generator to generate electricity. The water then flows through the defoaming device, which removes air bubbles. The pressure sensing device detects the water pressure in the outlet pipe. If the pressure is too high, the electric valve closes, blocking the water flow. Simultaneously, the pressure sensing device monitors the water flow within the pipe. When the pressure is uniform, the flow is laminar; when the pressure is uneven, the flow is turbulent. The regulating device changes the flow from turbulent to laminar, thereby increasing the stability of the water flow.

[0008] Furthermore, the water outlet pipe is provided with a first installation cavity, a second installation cavity, a third installation cavity, a first installation groove, a second installation groove, a fourth installation cavity, and a conical cavity. There are eight first installation cavities, which are evenly distributed radially along the water outlet pipe and are connected to the defoaming device. There are twelve second installation cavities, which are evenly distributed radially along the water outlet pipe and are connected to the defoaming device. There are four third installation cavities, which are evenly distributed radially along the water outlet pipe and are connected to the pressure sensing device. There are several first installation grooves, which are evenly distributed radially along the water outlet pipe. There are several second installation grooves, which are connected to the adjusting device. There are several second installation grooves, which are evenly distributed radially along the water outlet pipe. The fourth installation cavity is connected to the conical cavity. There are several conical cavities, which are evenly distributed radially along the water outlet pipe. The defoaming device is connected to the fourth installation cavity and the conical cavity.

[0009] The first, second, third, and fourth mounting chambers, along with the conical cavity, serve as the mounting base, providing the installation position for the defoaming device. By evenly distributing these chambers radially along the outlet pipe, the defoaming device can comprehensively defoam the water flow within the outlet pipe, increasing the defoaming effect. The first mounting groove serves as the mounting base, providing the installation position for the pressure sensing device. Its even distribution radially along the outlet pipe allows the pressure sensing device to comprehensively detect the water flow pressure within the outlet pipe, increasing the accuracy of the pressure detection results. The second mounting groove serves as the mounting base, providing the installation position for the regulating device. Its even distribution radially along the outlet pipe allows the regulating device to comprehensively regulate the water flow within the outlet pipe, improving the efficiency of the water flow transition from turbulent to laminar flow, thereby enhancing the stability of the water flow.

[0010] Furthermore, the turbine generator, the first mounting cavity, the second mounting cavity, the third mounting cavity, the fourth mounting cavity, the conical cavity, the first mounting groove, and the second mounting groove are sequentially distributed in the water outlet direction of the water outlet pipe.

[0011] By sequentially distributing the turbine generator, the first mounting cavity, the second mounting cavity, the third mounting cavity, the fourth mounting cavity, the conical cavity, the first mounting groove, and the second mounting groove in the water outlet direction of the water outlet pipe, the water flow can first pass through the turbine generator to generate electricity, and then pass through the defoaming device to remove air bubbles from the water flow. The pressure sensing device detects the water flow pressure, and then, based on the water flow pressure detected by the pressure sensing device, it is determined whether the electric valve needs to be closed and the control and adjustment device needs to be used to change the flow state of the water flow.

[0012] Furthermore, the defoaming device includes a main magnetic ring, magnetic blocks, and a piezoelectric ring. The main magnetic ring is fitted onto the water outlet pipe and is securely connected to the water outlet pipe. There are several magnetic blocks, which are respectively placed in the first mounting cavity, the second mounting cavity, and the third mounting cavity. The piezoelectric ring is placed in the fourth mounting cavity and is securely connected to the fourth mounting cavity. The defoaming device also includes a defoaming tube, which is located downstream of the fourth mounting cavity and is placed inside the water outlet pipe. The defoaming tube and the water outlet pipe are securely connected.

[0013] The defoaming tube wall is coated with a needle-punched layer, which punctures air bubbles in the water. A piezoelectric ring is connected to a turbine generator, which is also connected to a power source for supplementary energy. The air bubbles in the water are diamagnetic; they are subjected to magnetic force in a magnetic field and can move along the direction of the magnetic field. Magnetic blocks placed in eight first mounting chambers exert a moderate magnetic field on the air bubbles, causing them to gradually move towards the center of the tube. Then, magnetic blocks in twelve second mounting chambers, along with the main magnetic ring, create a high-intensity magnetic field that further strengthens the force on the air bubbles, accelerating their movement towards the center. Finally, magnetic blocks in four third mounting chambers create a low-intensity magnetic field, allowing the accelerated air bubbles to move towards the tube wall by inertia while continuously experiencing a force directed towards the defoaming tube wall. The electrical energy generated by the turbine generator and the power source jointly drive the piezoelectric ring to vibrate. This vibration generates sound waves in the conical cavity, which then act on the outlet tube, causing the air bubbles to move faster towards the defoaming tube, thus improving the bubble removal efficiency.

[0014] Furthermore, the magnetic block in the first mounting cavity is deflected 30 degrees toward the electric valve, and the magnetic block in the third mounting cavity is deflected 60 degrees toward the water outlet direction of the water outlet pipe.

[0015] By deflecting the magnetic block in the first mounting cavity by 30 degrees, the magnetic field strength near the upstream of the first mounting cavity is increased, thereby increasing the range of the magnetic field acting on the bubbles and improving the effect of the bubbles moving to the defoaming tube. By deflecting the magnetic block in the third mounting cavity by 60 degrees, the range of the magnetic field acting on the bubbles downstream of the third mounting cavity is increased, thereby improving the bubble elimination effect.

[0016] Furthermore, the pressure-sensing device includes a pressure-sensing spring, a magnet, a spring, and an induction coil. The pressure-sensing spring is fastened to the first mounting slot, the magnet is fastened to the pressure-sensing spring, the end of the magnet away from the pressure-sensing spring is fastened to the spring, the end of the spring away from the pressure-sensing spring is fastened to the first mounting slot, the induction coil is fastened to the first mounting slot, and the spring is placed inside the induction coil.

[0017] When the water pressure in the outlet pipe changes, the force exerted by the water flow on the pressure-sensitive spring changes, causing the spring to deform. This deformation moves the magnet, which in turn changes the magnetic flux in the induction coil, generating an induced current. When the water pressure exceeds the specified range, the electrical signal generated by the induction coil controls the electric valve to close, thus protecting the pipeline. Simultaneously, a ring of pressure sensors detects the pressure at different locations in the outlet pipe. When the water flow is turbulent, the force exerted on the pressure sensors is unstable, causing fluctuations in the electrical signal generated by the induction coil. By detecting the fluctuation range of the electrical signal generated by the induction coil, a relative position adjustment device is used to adjust the flow, transforming the turbulence into laminar flow.

[0018] Furthermore, the adjustment device includes an adjustment motor and an adjustment plate. The adjustment motor is placed in the second mounting slot, and the adjustment motor and the second mounting slot are fastened together. The output end of the adjustment motor and the adjustment plate are fastened together.

[0019] The pressure-sensing device detects the location of the turbulent water flow, and then controls the output torque of the adjusting motor to rotate the adjusting plate according to the generated electrical signal. This increases the flow area of ​​the water flow at that location, allowing the water flow to change from turbulent to laminar flow, thus enhancing the stability of the water flow.

[0020] Furthermore, the regulating plate has a streamlined cross-section, and the regulating plate gradually narrows along the water outlet direction of the water outlet pipe.

[0021] By setting the regulating plate to a streamlined shape, the effect of transforming turbulent water flow into laminar water flow is enhanced, thereby improving the stability of the water flow during the flow process.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The pressure sensing device enables precise detection of water pressure within the outlet pipe. When the water pressure changes, the pressure-sensing spring deforms, causing the magnet to move, which in turn changes the magnetic flux within the induction coil and generates an induced current, thus enabling timely detection of abnormal pressure conditions. Simultaneously, the pressure sensing device can also detect the water flow state. When turbulence is detected, the position of the regulating plate is adjusted by the regulating device to change the water flow area, transforming turbulence into laminar flow and effectively improving the stability of the water flow. This precise pressure sensing and automatic adjustment function greatly enhances the adaptability of the regulating valve to system pressure changes and reduces the adverse effects caused by pressure fluctuations.

[0024] 2. The defoaming device cleverly combines the effects of magnetic fields and sound waves to achieve highly efficient removal of air bubbles from water flow. Air bubbles in water, being diamagnetic, experience a force in a magnetic field. By placing magnetic blocks of different angles and intensities in different installation cavities, a gradient magnetic field is created, causing the bubbles to move towards the center of the pipe in the water flow, and then accelerate towards the pipe wall. Simultaneously, the vibration of the piezoelectric ring generates sound waves through the conical cavity, further accelerating the bubbles towards the defoaming tube, where they are finally punctured by the needle-piercing coating on the tube wall. This comprehensive, multi-stage defoaming method significantly improves the efficiency of bubble removal and reduces the adverse effects of bubbles on the fluid transport system, such as cavitation and reduced transport efficiency.

[0025] 3. Energy Recovery and Utilization: The turbine generator is designed to drive the water flow and generate electricity. This electricity can power components such as the piezoelectric ring and also serve as supplementary energy, realizing the recovery and utilization of fluid kinetic energy, improving the overall system's energy efficiency, and reducing energy waste.

[0026] 4. The regulating plate adopts a streamlined design and gradually narrows along the water outlet direction, which further enhances the effect of converting turbulent flow into laminar flow and improves the stability of the water flow. Attached Figure Description

Detailed Implementation

[0038] 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.

[0039] Example: Figures 1-10 As shown, the present invention provides a self-closing regulating valve with pressure-sensing regulation function. The self-closing regulating valve includes an electric valve 1, an inlet pipe 2, an outlet pipe 3, a turbine generator 4, a defoaming device 5, a pressure-sensing device 6, and a regulating device 7. The electric valve 1 and the inlet pipe 2 are connected by pipes, and the electric valve 1 and the outlet pipe 3 are also connected by pipes. The turbine generator 4 is placed inside the outlet pipe 3 and is securely connected to the outlet pipe 3. The defoaming device 5 is connected to the outlet pipe 3. The pressure-sensing device 6 is placed inside the outlet pipe 3 and is securely connected to the outlet pipe 3. The regulating device 7 is placed inside the outlet pipe 3 and is connected to the outlet pipe 3.

[0040] Electric valve 1 serves as the main mounting base for installing other components. When electric valve 1 is opened, water flows sequentially through inlet pipe 2, electric valve 1, outlet pipe 3, turbine generator 4, defoaming device 5, pressure sensing device 6, and regulating device 7, before exiting from the outlet pipe 3. When the water flows through turbine generator 4, it drives the turbine generator 4 to generate electricity. The water then flows through defoaming device 5, which removes air bubbles from the water. Pressure sensing device 6 detects the water pressure in outlet pipe 3. When pressure sensing device 6 detects excessive pressure, electric valve 1 closes, blocking the water flow. Simultaneously, pressure sensing device 6 detects the water flow within the pipe. When the water pressure is uniform, the water flow is laminar; when the water pressure is uneven, the water flow is turbulent. Regulating device 7 changes the water flow from turbulent to laminar flow, thereby increasing the stability of the water flow.

[0041] like Figures 3-10 As shown, the water outlet pipe 3 is provided with a first mounting cavity 31, a second mounting cavity 32, a third mounting cavity 33, a first mounting groove 34, a second mounting groove 35, a fourth mounting cavity 36, and a conical cavity 37. There are eight first mounting cavities 31, which are evenly distributed radially along the water outlet pipe 3. The first mounting cavities 31 are connected to the defoaming device 5. There are twelve second mounting cavities 32, which are evenly distributed radially along the water outlet pipe 3. The second mounting cavities 32 are connected to the defoaming device 5. There are four third mounting cavities 33, which are evenly distributed radially along the water outlet pipe 3. Pipe 3 is radially evenly distributed. The first mounting groove 34 is connected to the pressure sensing device 6. There are several first mounting grooves 34, which are evenly distributed radially along the outlet pipe 3. The second mounting groove 35 is connected to the adjusting device 7. There are several second mounting grooves 35, which are evenly distributed radially along the outlet pipe 3. The fourth mounting cavity 36 is connected to the conical cavity 37. There are several conical cavities 37, which are evenly distributed radially along the outlet pipe 3. The defoaming device 5 is connected to the fourth mounting cavity 36 and the conical cavity 37.

[0042] The first mounting cavity 31, the second mounting cavity 32, the third mounting cavity 33, the fourth mounting cavity 36, and the conical cavity 37 serve as the mounting base, providing the mounting position for the defoaming device 5. By uniformly distributing the first mounting cavity 31, the second mounting cavity 32, the third mounting cavity 33, and the conical cavity 37 radially along the water outlet pipe 3, the defoaming device 5 can effectively defoam the water flow in the water outlet pipe 3 from all directions, increasing the defoaming effect. The first mounting groove 34 serves as the mounting base, providing the mounting position for the pressure sensing device 6. By uniformly distributing the first mounting groove 34 radially along the water outlet pipe 3, the pressure sensing device 6 can perform pressure detection of the water flow in the water outlet pipe 3 from all directions, increasing the accuracy of the water flow pressure detection results. The second mounting groove 35 serves as the mounting base, providing the mounting position for the regulating device 7. By uniformly distributing the second mounting groove 35 radially along the water outlet pipe 3, the regulating device 7 can comprehensively regulate the water flow in the water outlet pipe 3, improving the conversion efficiency of the water flow from turbulent to laminar flow, thereby improving the stability of the water flow.

[0043] like Figures 2-10 As shown, the turbine generator 4, the first mounting cavity 31, the second mounting cavity 32, the third mounting cavity 33, the fourth mounting cavity 36, the conical cavity 37, the first mounting groove 34 and the second mounting groove 35 are sequentially distributed in the water outlet direction of the water outlet pipe 3.

[0044] By sequentially distributing the turbine generator 4, the first mounting cavity 31, the second mounting cavity 32, the third mounting cavity 33, the fourth mounting cavity 36, the conical cavity 37, the first mounting groove 34, and the second mounting groove 35 in the water outlet direction of the water outlet pipe 3, the water flow can first pass through the turbine generator 4 to generate electricity, and then pass through the defoaming device 5 to remove air bubbles from the water flow. The pressure sensing device 6 detects the pressure of the water flow, and then, based on the water flow pressure detected by the pressure sensing device 6, it is determined whether it is necessary to close the electric valve 1 and control the regulating device 7 to change the flow state of the water flow.

[0045] like Figures 3-7 As shown, the defoaming device 5 includes a main magnetic ring 51, a magnetic block 52, and a piezoelectric ring 53. The main magnetic ring 51 is fitted onto the water outlet pipe 3, and the main magnetic ring 51 and the water outlet pipe 3 are tightly connected. There are several magnetic blocks 52, which are respectively placed in the first mounting cavity 31, the second mounting cavity 32, and the third mounting cavity 33. The piezoelectric ring 53 is placed in the fourth mounting cavity 36, and the piezoelectric ring 53 and the fourth mounting cavity 36 are tightly connected. The defoaming device 5 also includes a defoaming tube 54, which is located downstream of the fourth mounting cavity 36 and placed in the water outlet pipe 3. The defoaming tube 54 and the water outlet pipe 3 are tightly connected.

[0046] The defoaming tube 54 has a needle-punched coating on its wall to puncture air bubbles in the water. A piezoelectric ring 53 is connected to a turbine generator 4 and also to a power source for supplementary energy. The air bubbles in the water are diamagnetic and can move along the magnetic field. Magnetic blocks 52 placed in the eight first mounting cavities 31 exert a moderate magnetic field on the air bubbles, causing them to gradually move towards the center of the tube. Then, a high-intensity magnetic field formed by the twelve magnetic blocks 52 in the twelve second mounting cavities 32 and the main magnetic ring 51 further strengthens the force on the air bubbles. The force of the bubbles causes them to move towards the center of the tube at an accelerated speed. Then, the low-intensity magnetic field formed by the magnetic blocks 52 in the four third mounting cavities 33 causes the bubbles, accelerated by the high-intensity magnetic field, to move towards the tube wall by inertia while continuously being subjected to a force pointing towards the wall of the defoaming tube 54. The electrical energy generated by the turbine generator 4 and the power supply drive together to drive the piezoelectric ring 53 to vibrate. The vibration of the piezoelectric ring 53 causes the conical cavity 37 to generate sound waves. The sound waves generated by the conical cavity 37 act on the water outlet pipe 3, causing the bubbles to be accelerated towards the defoaming tube 54 by the force of the sound waves, thus improving the bubble removal efficiency.

[0047] like Figures 3-7 As shown, the magnetic block 52 in the first mounting cavity 31 is deflected 30 degrees toward the electric valve 1, and the magnetic block 52 in the third mounting cavity 33 is deflected 60 degrees toward the water outlet direction of the water outlet pipe 3.

[0048] By deflecting the magnetic block 52 in the first mounting cavity 31 by thirty degrees, the magnetic field strength near the upstream of the first mounting cavity 31 is increased, thereby increasing the range of the bubbles affected by the magnetic field and improving the effect of the bubbles moving to the defoaming tube 54. By deflecting the magnetic block 52 in the third mounting cavity 33 by sixty degrees, the range of the bubbles downstream of the third mounting cavity 33 is increased, thereby improving the bubble elimination effect.

[0049] like Figures 8-9 As shown, the pressure-sensing device 6 includes a pressure-sensing spring 61, a magnet 62, a spring 63, and an induction coil 64. The pressure-sensing spring 61 is fastened to the first mounting groove 34, the magnet 62 is fastened to the pressure-sensing spring 61, the end of the magnet 62 away from the pressure-sensing spring 61 is fastened to the spring 63, the end of the spring 63 away from the pressure-sensing spring 61 is fastened to the first mounting groove 34, the induction coil 64 is fastened to the first mounting groove 34, and the spring 63 is placed inside the induction coil 64.

[0050] When the water pressure in the outlet pipe 3 changes, the force exerted by the water flow on the pressure-sensitive spring 61 changes, causing the spring 61 to deform. This deformation causes the magnet 62 to move, which in turn changes the magnetic flux in the induction coil 64, generating an induced current. When the water pressure exceeds the range, the electrical signal generated by the induction coil 64 controls the electric valve 1 to close, thus protecting the pipeline. Simultaneously, the pressure at different locations in the outlet pipe 3 is detected by the ring-shaped pressure-sensitive devices 6. When the water flow is turbulent, the force exerted by the turbulent flow on the pressure-sensitive devices 6 is unstable, causing fluctuations in the electrical signal generated by the induction coil 64. By detecting the fluctuation range of the electrical signal generated by the induction coil 64, the relative position adjustment device 7 adjusts the effect of transforming turbulence into laminar flow.

[0051] like Figure 10 As shown, the adjustment device 7 includes an adjustment motor 71 and an adjustment plate 72. The adjustment motor 71 is placed in the second mounting slot 35 and the adjustment motor 71 and the second mounting slot 35 are fastened together. The output end of the adjustment motor 71 is fastened together with the adjustment plate 72.

[0052] The pressure sensing device 6 detects the position of the water turbulence, and then controls the adjustment motor 71 to output torque according to the generated electrical signal to make the adjustment plate 72 rotate, thereby increasing the flow area of ​​the water at that position, so that the water flow can change from turbulent flow to laminar flow, and enhancing the stability of the water flow.

[0053] like Figure 10 As shown, the cross-section of the regulating plate 72 is streamlined, and the regulating plate 72 gradually narrows along the water outlet direction of the water outlet pipe 3.

[0054] By setting the regulating plate 72 to a streamlined shape, the effect of converting turbulent water flow into laminar water flow is enhanced, and the stability of the water flow during the flow process is improved.

[0055] The working principle of this invention: The electric valve 1 serves as the main mounting base for installing other components. When the electric valve 1 is opened, water flows sequentially through the inlet pipe 2, the electric valve 1, the outlet pipe 3, the turbine generator 4, the defoaming device 5, the pressure sensing device 6, and the regulating device 7, and then flows out from the outlet pipe 3. When the water flows through the turbine generator 4, the water flow drives the turbine generator 4 to operate, thereby generating electrical energy. Then, the water flows through the defoaming device 5, and through the magnetic blocks 52 placed in the eight first mounting chambers 31, a moderately strong magnetic field exerts a force on the air bubbles in the water flow, allowing the air bubbles to gradually move towards the center of the pipe. Then, through the magnetic blocks 52 in the twelve second mounting chambers 32, the high-intensity magnetic field formed by the twelve magnetic blocks 52 and the main magnetic ring 51 strengthens the force on the air bubbles, allowing the air bubbles to move towards the center of the pipe more rapidly. Finally, through the low-intensity magnetic field formed by the magnetic blocks 52 in the four third mounting chambers 33, the water flow is further accelerated. The bubbles, accelerated by the high-intensity magnetic field, move towards the pipe wall by inertia while continuously being subjected to a force pointing towards the wall of the defoaming pipe 54. The electrical energy generated by the turbine generator 4 and the power supply drive the piezoelectric ring 53 to vibrate. The vibration of the piezoelectric ring 53 causes the conical cavity 37 to generate sound waves. The sound waves generated by the conical cavity 37 act on the water outlet pipe 3, causing the bubbles to be accelerated towards the defoaming pipe 54 by the force of the sound waves, thus improving the bubble removal efficiency. Then, the pressure sensing device 6 detects the water pressure in the water outlet pipe 3. When the pressure sensing device 6 detects that the pressure is too high, the electric valve 1 closes to block the water flow. At the same time, the pressure sensing device 6 detects the water flow in the pipe. When the water pressure is uniform, the water flow is in a laminar state. When the water pressure is uneven, the water flow is in a turbulent state. The regulating device 7 changes the water flow state from turbulent to laminar flow, thereby increasing the stability of the water flow.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
