Description

Technical Field

[0001] This invention relates to the field of water valve technology, and more specifically to an IoT-controlled thermal water inlet valve with water level monitoring. Background Technology

[0002] An inlet valve is a valve used to control the flow of water into equipment or systems. It is widely used in hydropower stations, heating systems, toilet tanks, and household water pipes. Its core function is to regulate water supply, protect equipment, and maintain systems by opening or closing the water flow.

[0003] Among them, the patent with publication number CN118640316A discloses a remote control float valve, including a remote control float valve body, a connecting pipe fixedly connected to the top surface of the remote control float valve body, a control valve installed on the connecting pipe, an annular pipe fixedly connected to the connecting pipe, a number of through holes evenly distributed on the outer side wall of the annular pipe, an adjustable sealing component provided in each through hole, a fixed pipe inserted into one of the through holes, the fixed pipe and the annular pipe being fixedly connected, a guide tube fixedly connected to the end of the fixed pipe away from the annular pipe, a switch component fixedly connected to the end of the guide tube away from the fixed pipe, an adjustable connecting component installed on the switch component, and a float fixedly connected to the adjustable connecting component;

[0004] In use, this structure, with its annular tube, through hole, fixed tube, and adjustable sealing assembly, allows the float to be installed at a suitable position on the valve body of the remote-controlled float valve via the installation of the conduit. The fixed tube pushes the vertical plate, which in turn pushes the baffle via the movable rod, thus connecting the inner tube and the inner cavity of the annular tube. This enables the function of a remote-controlled float valve and facilitates its use. However, this structure makes it difficult to adjust the float's movable range during use, resulting in insufficient flow control accuracy. Summary of the Invention

[0005] This invention provides an IoT-controlled thermal water inlet valve with water level monitoring, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an IoT-controlled thermal water inlet valve with water level monitoring, comprising a valve body, wherein a regulating component is provided on the valve body.

[0007] The control component includes a central disc located at the top of the valve body cavity, a floating disc located in the center of the central disc, a floating plate located on the outer side of the floating disc, and several diversion slots extending through the floating plate. Several linkage plates are fixedly installed on the outer side of the floating plate.

[0008] A flow sensor is installed in the middle of the floating roof. A spring is sleeved on the outside of the flow sensor, and the bottom end of the spring extends to the floating roof and is slidably connected to the floating roof. A pressure plate is fixedly installed on the top of the spring.

[0009] A central ring is fixedly installed at the bottom of the flow sensor. Several turbines are installed in the middle of the central ring. The turbines are located at the bottom of the inner cavity of the valve body and are rotatably connected to the valve body. The pressure plate is sleeved on the flow sensor and is rotatably connected to the flow sensor. The float is installed on the outside of the flow sensor by a nut. A float support plate is installed at the bottom of the float and is fixed to the outside of the flow sensor. A sealing cover is fixedly installed at the bottom of the float support plate. An inner liner plate is installed at the bottom of the sealing cover. The inner liner plate is located at the top of the central ring. A cavity is opened in the middle of the inner liner plate. A sealing element is fixedly installed at the bottom of the inner cavity. The top of the sealing element extends to the middle of the sealing cover.

[0010] As can be seen, in the above technical solution, the central ring and turbine rotate due to the pressure of the cut-off delivery, which in turn enables the flow sensor to rotate. The pulse signal of the flow sensor is counted by the magnetic induction of the pulse sensor. While the lead screw rotates, it extends downward from the lead screw motor and abuts against the pressure plate, allowing the pressure plate to move downward and compress the spring. The elastic deformation of the spring can absorb the impact energy of the water flow, and when the float plate, the float support plate, and the inner liner plate fluctuate slightly, the spring extends and retracts without triggering the valve action. The valve is only driven when the water level continuously deviates from the set value. Furthermore, by adjusting the spring preload or deformation range, the effective displacement range of the float plate, the float support plate, and the inner liner plate can be dynamically set. The water level trigger point can be finely adjusted without disassembly, achieving the balance of instantaneous force changes on the float plate, the float support plate, and the inner liner plate while avoiding false water level signals caused by sudden pressure changes.

[0011] A lead screw is provided on the top of the pressure plate, and a plug rod is fixedly provided at the bottom end of the lead screw and inserted into the top of the flow sensor. A valve cover is bolted to the top of the valve body, and a pulse sensor is provided on the valve cover. The pulse sensor extends to the bottom of the valve cover. A first pressure sensor is provided on the side of the valve cover away from the pulse sensor. A detection rod is provided at one end of the first pressure sensor. A second pressure sensor is provided at the bottom end of the detection rod and extends into the valve body. A lead screw motor is bolted to the top of the valve cover, and the lead screw extends into the lead screw motor and is threadedly connected to the lead screw motor. A first drain pipe for guiding flow is provided on one side of the valve body, and a second drain pipe for guiding flow is provided on the other side of the valve body. Several filter strips are fixedly provided on the top of the central plate, and several impurity storage cavities, each penetrating the filter strips, are opened on the upper surface of the central plate.

[0012] As can be seen, in the above technical solution, when the water flow passes around the central ring and turbine, it can push the inner liner plate and the float plate to move upward, thereby allowing the water flow to be delivered between the valve body and the valve cover. The water flow flows between the valve body and the valve cover and comes into contact with the float plate and the linkage plate. When the water flow comes into contact with the diversion channel and the linkage plate, it can push the float plate and the float plate to rotate, thereby allowing the flow sensor to rotate synchronously. The vortex frequency generated by the fluid passing around the diversion channel and the linkage plate and causing the float plate to rotate is detected. Combined with the pulse signal of the pulse sensor magnetic induction counting flow sensor, the flow rate during water delivery is detected, ensuring detection accuracy.

[0013] The present invention has the following advantages:

[0014] 1. The present invention can absorb the impact energy of water flow through the elastic deformation of the spring, and the spring can extend and retract without triggering the valve action when the float plate, the float support plate and then the inner lining plate fluctuate slightly. The valve is only driven when the water level continuously deviates from the set value.

[0015] 2. By adjusting the spring preload or deformation range, the effective displacement range of the float plate, the buoy plate and the inner liner plate can be dynamically set. The water level trigger point can be finely adjusted without disassembly and assembly, so as to balance the instantaneous force changes on the float plate, the buoy plate and the inner liner plate while avoiding false water level signals caused by sudden pressure changes.

[0016] 3. When water is being transported, it comes into contact with the turbine. The central ring and the turbine rotate due to the pressure that stops the transport, which in turn causes the flow sensor to rotate. The pulse sensor counts the pulse signal of the flow sensor through magnetic induction by the pulse sensor, and the turbine converts the kinetic energy of the water into rotational motion. The flow sensor measures the water consumption in real time to achieve water conservation and throttling. It also facilitates the monitoring of water flow data and feedback to the Internet of Things, dynamically adjusts the valve opening, reduces ineffective water flow, and achieves intelligent water conservation and throttling.

[0017] 4. This invention enables the water flow to bypass the central ring and turbine, thus pushing the inner liner plate and the floating plate upward. When the water flow comes into contact with the diversion channel and the linkage plate, it can drive the floating plate and the floating disk to rotate, thereby enabling the flow sensor to rotate synchronously. The vortex frequency generated by the fluid bypassing the diversion channel and the linkage plate and causing the floating plate to rotate is detected. Combined with the pulse signal of the pulse sensor magnetic induction counting flow sensor, the flow rate during water flow is detected, ensuring detection accuracy.

[0018] In summary, this invention utilizes the elastic deformation characteristics of springs to enable valves to absorb the instantaneous impact energy of water flow, effectively filtering out minor vibrations of the float plate, float support plate, and inner liner plate caused by pressure fluctuations. This prevents accidental valve activation and ensures that the valve only responds and adjusts when the water level continuously deviates from the set value, significantly improving the stability and reliability of control. Furthermore, by using a lead screw motor to drive the lead screw to adjust the preload or deformation range of the spring, the effective displacement range of the float plate assembly can be dynamically set, achieving stepless fine-tuning of the water level trigger point. Water flow drives the turbine and central ring to rotate, causing the flow sensor to generate pulse signals. The diversion channel and linkage plate further convert the water flow vortex frequency into the rotational motion of the float plate. Combined with the magnetic induction counting technology of the pulse sensor, the flow rate is detected in real time. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] As attached Figure 1-8 The illustrated IoT-controlled thermal water inlet valve with water level monitoring utilizes a regulating component on the valve body 1 and the elastic deformation characteristics of the spring 7 to absorb the instantaneous impact energy of the water flow. This effectively filters out the minute vibrations of the float plate 4, float support plate 11, and inner liner plate 13 caused by pressure fluctuations, preventing accidental valve activation. The valve only responds and adjusts when the water level continuously deviates from the set value, significantly improving the stability and reliability of the control. Furthermore, the screw motor 23 drives the screw 16 to adjust the preload or deformation range of the spring 7, dynamically setting the effective displacement range of the float plate assembly and achieving stepless fine-tuning of the water level trigger point. The water flow drives the turbine 10 and the central ring 9 to rotate, causing the flow sensor 6 to generate a pulse signal. The diversion channel 5 and the linkage plate 28 further convert the water flow vortex frequency into the rotational motion of the float plate 4. Combined with the magnetic induction counting technology of the pulse sensor 19, the flow rate is detected in real time. The specific structural settings of the components are as follows.

[0031] The control component includes a central disc 2 located at the top of the inner cavity of the valve body 1, a float 3 located in the middle of the central disc 2, a float plate 4 located on the outer side of the float 3, and several diversion grooves 5 extending through the float plate 4. Several linkage plates 28 are fixedly installed on the outer side of the float plate 4.

[0032] A flow sensor 6 is provided in the middle of the floating plate 3. A spring 7 is sleeved on the outside of the flow sensor 6, and the bottom end of the spring 7 extends to the floating plate 3 and is slidably connected to the floating plate 3. A pressure plate 8 is fixedly provided on the top of the spring 7.

[0033] A central ring 9 is fixedly installed at the bottom of the flow sensor 6. Several turbines 10 are installed in the middle of the central ring 9. The turbines 10 are located at the bottom of the inner cavity of the valve body 1 and are rotatably connected to the valve body 1. The pressure plate 8 is sleeved on the flow sensor 6 and is rotatably connected to the flow sensor 6. The float plate 3 is installed on the outside of the flow sensor 6 by a nut. A float support plate 11 is installed at the bottom of the float plate 3. The float support plate 11 is fixed on the outside of the flow sensor 6. A sealing cover 12 is fixedly installed at the bottom of the float support plate 11. An inner liner plate 13 is installed at the bottom of the sealing cover 12. The inner liner plate 13 is located at the top of the central ring 9. A cavity 14 is opened in the middle of the inner liner plate 13. A sealing element 15 is fixedly installed at the bottom of the inner cavity 14. The top of the sealing element 15 extends to the middle of the sealing cover 12.

[0034] A lead screw 16 is provided on the top of the pressure plate 8. A plug rod 17, which is inserted into the top of the flow sensor 6, is fixedly provided at the bottom end of the lead screw 16. A valve cover 18 is installed on the top of the valve body 1 by bolts. A pulse sensor 19 is provided on the valve cover 18. The pulse sensor 19 extends to the bottom of the valve cover 18. A first pressure sensor 20 is provided on the side of the valve cover 18 away from the pulse sensor 19. A detection rod 21 is provided at one end of the first pressure sensor 20. A second pressure sensor 22, which extends into the valve body 1, is provided at the bottom end of the detection rod 21. A lead screw motor 23 is installed on the top of the valve cover 18 by bolts. The lead screw 16 extends into the lead screw motor 23 and is threadedly connected to the lead screw motor 23. A first drain pipe 24 for guiding flow is provided on one side of the valve body 1. A second drain pipe 25 for guiding flow is provided on the other side of the valve body 1. Several filter strips 26 are fixedly provided on the top of the central plate 2. Several impurity storage cavities 27, which all penetrate the filter strips 26, are opened on the upper surface of the central plate 2.

[0035] The specific working principle is as follows: the inlet valve is installed on the pipeline through a flange, and the water flow from the pipeline is delivered to the valve body 1. When the water flow is delivered, it comes into contact with the turbine 10. The central ring 9 and the turbine 10 rotate due to the pressure of the cut-off delivery, which in turn enables the flow sensor 6 to rotate. The pulse signal of the flow sensor 6 is counted by the magnetic induction of the pulse sensor 19.

[0036] Furthermore, after the water flow passes around the central ring 9 and the turbine 10, it can push the inner liner plate 13 and the float plate 11 to move upward, thereby allowing the water flow to be delivered between the valve body 1 and the valve cover 18. The water flow flows between the valve body 1 and the valve cover 18 and comes into contact with the float plate 4 and the linkage plate 28. When the water flow comes into contact with the diversion channel 5 and the linkage plate 28, it can push the float plate 4 and the float disk 3 to rotate, thereby allowing the flow sensor 6 to rotate synchronously. The vortex frequency generated by the fluid passing around the diversion channel 5 and the linkage plate 28 and causing the float plate 4 to rotate is detected. Combined with the pulse signal of the pulse sensor 6, the magnetic induction counting flow sensor 6 is used to detect the flow rate during water delivery, ensuring detection accuracy.

[0037] Furthermore, during use, the device can drive the lead screw 16 to rotate via the lead screw motor 23. As the lead screw 16 rotates, it extends downward from the lead screw motor 23 and abuts against the pressure plate 8, allowing the pressure plate 8 to move downward and compress the spring 7. The elastic deformation of the spring 7 can absorb the impact energy of the water flow, and when the float plate 4, the float support plate 11, and the inner liner plate 13 fluctuate slightly, the spring 7 extends and retracts without triggering the valve action. The valve is only activated when the water level continuously deviates from the set value. Moreover, by adjusting the preload or deformation range of the spring 7, the effective displacement range of the float plate 4, the float support plate 11, and the inner liner plate 13 can be dynamically set. The water level trigger point can be finely adjusted without disassembly, achieving the balance of instantaneous force changes on the float plate 4, the float support plate 11, and the inner liner plate 13 while avoiding false water level signals caused by sudden pressure changes.

[0038] Furthermore, when the water flow inside the valve body 1 loses power, the inner liner plate 13 and the float plate 11 are reset by the elasticity of the spring 7, so that the inner liner plate 13 and the sealing cover 12 come into contact with each other, while the sealing element 15 deforms to fill the gap between the sealing cover 12 and the inner liner plate 13, thereby achieving the function of sealing the bottom of the valve body 1 and making it easy to block the valve body 1.

[0039] Furthermore, the first pressure sensor 20 and the second pressure sensor 22 are respectively installed at different positions inside the valve cover 18 and the valve body 1 to monitor the water pressure difference inside the valve cover 18 and the valve body 1 in real time. When the water pressure fluctuates, the two sensors work together to provide accurate pressure data feedback to the control system. The filter strip 26 is located at the top of the central disc 2 and is used to intercept solid impurities (such as mud, sand, particles, etc.) in the water flow to prevent them from entering the internal structure of the valve and avoid jamming or wear of key components. The impurity storage chamber 27 is a cavity design that runs through the filter strip 26. Its function is to collect and store the impurities intercepted by the filter strip.

[0040] Furthermore, the water flow pushes the float plate 11 and the inner lining plate 13 to float, causing the float plate 4 and the float disk 3 to move as a whole. The displacement of the float plate 4 is transmitted to the pressure plate 8 through the spring 7. The elastic deformation of the spring 7 absorbs instantaneous fluctuations and avoids false triggering. It will only trigger the screw motor 23 to drive the screw 16 to press down or release when the water level continuously deviates from the set value (such as continuous rise or fall) and the displacement of the float plate 4 exceeds the buffer zone of the spring 7, thereby adjusting the valve opening.

[0041] Furthermore, several turbines 10 set on the central ring 9 are used to convert the kinetic energy of water into rotational motion. The flow sensor 6 measures the water consumption in real time to achieve water conservation and flow reduction. It also facilitates the monitoring of water flow data and feedback to the Internet of Things, dynamically adjusts the valve opening, reduces ineffective water flow, and achieves intelligent water conservation and flow reduction.

[0042] Unlike existing technologies, this application discloses an IoT-controlled thermal inlet valve with water level monitoring. Utilizing the elastic deformation characteristics of spring 7, the valve absorbs the instantaneous impact energy of the water flow, effectively filtering out minor vibrations of the float 4, float support plate 11, and inner liner plate 13 caused by pressure fluctuations. This prevents accidental valve activation, ensuring the valve only responds and adjusts when the water level continuously deviates from the set value, significantly improving control stability and reliability. Furthermore, by using a lead screw motor 23 to drive the lead screw 16 to adjust the preload or deformation range of spring 7, the effective displacement range of the float assembly can be dynamically set, achieving stepless fine-tuning of the water level trigger point. The water flow drives the turbine 10 and central ring 9 to rotate, causing the flow sensor 6 to generate pulse signals. The diversion channel 5 and linkage plate 28 further convert the water flow vortex frequency into the rotational motion of the float 4. Combined with the magnetic induction counting technology of the pulse sensor 19, the flow rate is detected in real time.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
