Description

Technical Field

[0001] The invention relates to a ball valve structure with intelligent temperature control function. Background Art

[0002] In modern industrial applications, precise temperature control of fluid media is one of the key factors to ensure the normal operation of equipment and process stability. Especially in the chemical, petroleum, natural gas, HVAC and other industries, temperature control has a significant impact on product quality, equipment life and operational safety. Traditional ball valve structures are usually based on mechanical control and manual adjustment. Although this method can meet basic requirements in low-precision applications, it faces many challenges in high-precision temperature control systems.

[0003] Due to the limitations of its design structure, traditional ball valves are difficult to accurately sense and adjust the temperature of fluid media. The installation location of the temperature sensor is usually limited to the inlet or outlet, and the temperature distribution changes in the pipeline cannot be fully monitored. Therefore, when the fluid temperature changes drastically or fluctuates, traditional ball valves often find it difficult to provide timely and accurate responses.

[0004] Traditional ball valves lack effective temperature regulation functions. Once the fluid temperature exceeds the predetermined range, they must rely on external heating or cooling devices for adjustment. However, these devices often operate independently of the ball valve control system, making it difficult to achieve intelligent linkage control. This leads to lag and instability in the temperature regulation process, making it impossible to achieve precise control of the fluid temperature.

[0005] Therefore, those skilled in the art need a ball valve structure that has accurate temperature perception, fast adjustment, and intelligent control. Summary of the invention

[0006] The purpose of the present invention is to solve the above deficiencies in the prior art and provide a ball valve structure with an intelligent temperature control function, which can monitor the fluid temperature in real time through an intelligent temperature control system and accurately adjust the temperature and flow of the fluid under different working conditions. The following is a specific solution:

[0007] A ball valve structure with intelligent temperature control function, comprising an inlet, a control part, an outlet and a central pipe running through the above parts; a temperature sensing part is arranged on the inlet around the central axis of the central pipe, and four temperature sensing parts are arranged on the central pipe at equal distances; a predictive temperature control module and a thermal feedback calibration module are also arranged on the inlet, and the predictive temperature control module and the thermal feedback calibration module are electrically connected to the temperature sensing part; the central pipe in the control part comprises a first shunt pipe, a second shunt pipe, a third shunt pipe and a fourth shunt pipe, and a dynamic thermal adjustment is arranged between the first shunt pipe, the second shunt pipe, the third shunt pipe and the fourth shunt pipe The control section module is further provided with a regulating control unit, the dynamic heat regulating module is electrically connected to the regulating control unit, the control section is further provided with a flow regulating module, the flow regulating module comprises a plugging piece, a connecting rod unit and a plugging channel, the plugging piece can be moved in the plugging channel driven by the connecting rod unit, the plugging channel extends in the direction of the central pipe, the ferry piece is used to plug the first shunt pipe, the second shunt pipe and the third shunt pipe, the flow regulating module is electrically connected to the regulating control unit, the control section is further provided with a cut-off unit, the cut-off unit is used to plug the first shunt pipe, the second shunt pipe, the third shunt pipe and the fourth shunt pipe.

[0008] The valve structure includes an inlet, a control part, an outlet and a central pipe running through the above components. The central pipe is a fluid channel that connects the inlet and the outlet. The fluid medium flows and is regulated through this pipe. The control system of the ball valve consists of a temperature sensing part, a predictive temperature control module, a thermal feedback calibration module, a dynamic thermal regulation module, a regulation control unit, a flow regulation module and a monitoring module. These modules work together to achieve precise control and regulation of temperature and flow.

[0009] The temperature sensing unit is composed of four temperature sensors, which are evenly distributed on the central pipe and are respectively set at the inlet, control and outlet. By comparing the temperatures of the outlet and the inlet, the data can be transmitted to the thermal feedback calibration module. The thermal feedback calibration module is electrically connected to the temperature sensing unit. Due to the characteristics of the fluid, the temperatures of the four temperature sensors may be different. Therefore, after calibrating the temperature, the thermal feedback calibration module transmits the data to the adjustment control unit for more precise control.

[0010] The predictive temperature control module uses an algorithm to predict the trend of fluid temperature based on the data fed back by the temperature sensing unit and combines the historical temperature change rules, and makes adjustments in advance. The thermal feedback calibration module is used to correct the errors of the temperature sensing unit in real time to ensure the accuracy of the temperature control system. The combination of the two can achieve rapid temperature response and precise regulation. The regulation control unit controls the working status of the dynamic thermal regulation module and the flow regulation module based on the data provided by the thermal feedback calibration module, the monitoring module and the predictive temperature control module to ensure that the temperature fluctuates within the preset range.

[0011] Furthermore, the central axes of the first shunt tube, the second shunt tube, the third shunt tube and the fourth shunt tube are parallel to each other and the distances between the central axes are equal.

[0012] Furthermore, the dynamic heat regulation unit also includes a heating device, which is arranged between the central axes of the first shunt tube, the second shunt tube, the third shunt tube and the fourth shunt tube, and is cross-shaped, with each end of the heating device extending a distance to both sides.

[0013] Furthermore, the length of the distance is the radius length of the first diversion pipe.

[0014] Furthermore, a temperature sensing part is provided on the outlet part around the central axis of the central pipe, and four temperature sensing parts are provided, and the temperature sensing parts are equidistantly arranged on the central pipe. A monitoring module and a thermal feedback calibration module are also provided on the inlet part, and the monitoring module and the thermal feedback calibration module are electrically connected to the temperature sensing part.

[0015] Furthermore, the cut-off unit can move up and down, and the radius of the cut-off unit is the same as the radius of the central pipe.

[0016] Furthermore, the connecting rod unit is provided with two connecting rods, and the connecting rods are arranged on both sides of the ferry plate. Under the drive of the motor, the connecting rods can drive the ferry plate to move along the extension direction of the blocking channel.

[0017] Furthermore, the sensor material of the temperature sensing part is made of high-precision platinum alloy or tungsten alloy.

[0018] Furthermore, the heating device in the dynamic heat regulation module adopts silicon carbide-based ceramic material, and the heating method is electric heating.

[0019] Furthermore, the plugging piece is made of a composite material of stainless steel and polytetrafluoroethylene.

[0020] During actual use, the ball valve automatically adjusts its internal thermal regulation and flow control system according to the temperature data of the fluid. When the fluid temperature changes, the temperature sensing sensor will transmit the temperature signal to the predictive temperature control module. The latter predicts the temperature change trend through an algorithm and determines whether the heat source needs to be adjusted based on historical data. If the temperature trend exceeds the predetermined range, the dynamic thermal regulation module quickly provides or absorbs heat through the electric heating device to adjust the fluid temperature to the ideal range; at the same time, the flow regulation module adjusts the flow of each branch pipe according to the temperature and flow requirements to ensure that the flow rate of the fluid through each pipe matches the temperature to achieve stable control. The entire process is coordinated by the regulation control unit to ensure that the work of each module does not interfere with each other, ensuring that the ball valve can respond accurately and quickly under complex working conditions and maintain stable system operation.

[0021] Beneficial effects: The present invention uses multiple temperature sensing parts and intelligent prediction algorithms to enable the ball valve to monitor and accurately control the fluid temperature in real time, significantly improving the response speed and accuracy of temperature regulation; the electrical connection and data transmission between each module enable the temperature control system to achieve automatic adjustment, avoiding the lag of traditional manual adjustment or manual operation and improving control efficiency.

[0032] For the purpose of greater clarity, the invention is described in detail through the following examples.

[0033] The intelligent temperature-controlled ball valve structure in this embodiment is designed for use in a temperature control system in a chemical production line. The system requires maintaining a precise temperature range during the flow of different fluid media to ensure the stability and safety of the reaction. Specifically, the ball valve in this embodiment is used in a steam regulating device, which requires automatic adjustment of the steam temperature when the steam flow rate changes to ensure that the heat energy transfer during the reaction process is always within an ideal range.

[0034] The inlet portion 100 is connected to the inlet of the heating device 241 through a pipeline, and the fluid enters the ball valve through the inlet portion 100. Four temperature sensing portions 130 are evenly distributed around the central axis of the central pipe 220 on the inlet portion 100 for real-time monitoring of the temperature of the fluid. Each temperature sensing portion 130 is composed of a precision temperature sensor made of high-precision platinum alloy to ensure the accuracy of temperature measurement.

[0035] The control unit 200 includes four shunt pipes, namely the first shunt pipe 221, the second shunt pipe 222, the third shunt pipe 223 and the fourth shunt pipe 224. The central axes of these pipes are parallel to each other, and the distances between the pipes are equidistant. The fluid inside the pipes will pass through the dynamic thermal regulation module 240, which has a built-in heating device 241 to regulate the temperature of the fluid by electric heating. The material of the heating device 241 is silicon carbide-based ceramics, which can provide long-lasting and stable heating function at high temperatures.

[0036] The regulating and controlling unit 250 is connected to the temperature sensing unit 130, the predictive temperature control module 120 and the dynamic thermal regulating module 240 through electrical signals. It is mainly responsible for receiving data from each module and controlling the working state of the heating device 241 according to the set temperature range. When the temperature data fed back by the sensor of the temperature sensing unit 130 deviates from the preset range, the regulating and controlling unit 250 will issue an instruction to adjust the heating power of the heating device 241 to ensure that the temperature is restored to the predetermined range in time.

[0037] The flow regulating module 230 is composed of a plugging piece 231, a connecting rod unit 232 and a plugging channel 233. The connecting rod unit 232 is driven by a motor to drive the plugging piece 231 to move in the plugging channel 233, thereby adjusting the flow of the fluid. The flow regulating module 230 is electrically connected to the regulating control unit 250 to achieve linkage control of the flow and temperature. In this embodiment, the flow regulating module 230 is used to adjust the steam flow to ensure that the flow rate and temperature of the steam are maintained in a suitable range in a high temperature environment; Figure 3 The fully open state is shown. Figure 4 The three are shown as being closed, and it is understood that one or two can also be closed, such as Figure 5 Shown is the fully closed position.

[0038] The outlet part 300 is responsible for exporting the regulated fluid and transporting it to the equipment in the next link through a pipeline. A temperature sensing part 130 is also installed in the pipeline of the outlet part 300 to monitor the outlet fluid temperature to ensure that the outlet fluid temperature meets the system requirements.

[0039] The monitoring module 310 monitors the operating status of the ball valve in real time, including the temperature, flow rate and other operating parameters of the fluid. The user can understand the working status of the ball valve at any time through the monitoring interface. If a fault or abnormality occurs, the monitoring module 310 will alarm in time and prompt the operator to take corresponding measures.

[0040] This embodiment demonstrates the working process of a ball valve structure with intelligent temperature control function in actual application. Through high-precision temperature perception and predictive regulation, coupled with the coordinated work of dynamic thermal regulation and flow regulation, the high efficiency and precise control of the system are ensured. This intelligent temperature-controlled ball valve structure is suitable for industries such as chemical, petroleum, and natural gas that require precise temperature control, and is of great significance for improving production efficiency and operational safety.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
