[0026] With the continuous improvement of people's living standards, residents' demand for water, electricity, heat, gas and other energy is also increasing. At present, the heating method for residents is mostly centralized heating. When the total heat is not enough, the heating situation of each area of ​​the heating pipeline cannot be controlled in time, which is easy to cause some unnecessary heat waste, resulting in insufficient heat supplied to residents' homes, affecting the quality of life of residents.

[0027] In order to solve the above problems, the utility model proposes a self-adjustable heat metering instrument, which aims to control the heat in the central heating pipeline in time and ensure the heat supplied to residents' homes when the total heat is insufficient. Figure 1 to Figure 2The present invention is a schematic structural diagram of an embodiment of a self-adjustable heat metering instrument provided by the present invention.

[0028] Please refer to Figure 1 to Figure 2 The utility model proposes a self-adjustable heat metering instrument 1000, including an ultrasonic heat metering instrument 1 and an electric regulating valve 2. The ultrasonic heat metering instrument 1 is connected to a heating pipeline, and includes a detection module, a control module and a display module 11. The detection module is used to detect the instantaneous flow of the thermal fluid in the pipeline. The control module is electrically connected to the detection module and the display module 11 to receive the electrical signal fed back by the detection module and display it through the display module 11; the electric regulating valve 2 is electrically connected to the ultrasonic heat metering instrument 1, and is installed in the heating pipeline at an interval with the ultrasonic heat metering instrument 1 to feed back the electrical signal of the control module to adjust the flow of the thermal fluid in the heating pipeline.

[0029] In the technical solution of the utility model, a self-adjustable heat meter 1000 is proposed, including an ultrasonic meter and an electric regulating valve 2, which are connected to the heating pipe at intervals. The flow rate of the hot fluid in the main pipe is detected and fed back by the detection module of the ultrasonic meter, and the electric regulating valve 2 is controlled by an electrical signal according to the detection result to control and adjust the flow rate of the branch pipe, so that the heat that can be delivered to the residents' homes is sufficient, thereby ensuring the quality of life of the residents.

[0030] In an optional embodiment, in order to ensure accurate detection of the hot fluid in the heating pipe, the detection module includes an ultrasonic sensor and a temperature sensor, which are connected to the heating pipe and electrically connected to the control module and the display module 11 to detect the flow and temperature in the heating pipe respectively. The temperature and flow in the heating pipe are monitored at any time by combining the ultrasonic sensor and the temperature sensor and digitally displayed by the display module 11, so as to respond to the flow of the total hot fluid in time and make corresponding adjustments. The adjustment method can be manually adjusted by the operator or by setting a preset value for the control module in advance. When the flow in the heating pipe is detected to be lower than the preset value, the control module sends an electrical signal to the electric regulating valve 2 to adjust the flow in the branch pipe accordingly, so as to ensure that the user's home can supply enough heat. The detection module includes an ultrasonic sensor and a temperature sensor, which are connected to the heating pipe and electrically connected to the control module and the display module 11 to detect the flow and temperature in the heating pipe respectively.

[0031] Specifically, the control module further includes a first controller and a data processing unit, and the data processing unit is electrically connected to the first controller. The data processing unit receives the detection data of the detection module, processes the received data, and sends different types of response signals to the first controller for the processing results, and transmits the electrical signals sent by the first controller to the electric regulating valve 2. The electric regulating valve 2 adjusts the opening and closing size of the branch pipe according to different detection results of the heating pipe, and controls the size of the thermal fluid flow in the branch pipe.

[0032] In an optional embodiment, in order to facilitate the operator to observe the detection results of the ultrasonic heat meter 1, the display module 11 includes a liquid crystal display screen, which is electrically connected to the control module and the electric regulating valve 2 to display the instantaneous flow in the pipeline. Figure 1 The liquid crystal display screen is electrically connected to the detection module and the control module to display the detection results of the ultrasonic sensor and the temperature sensor in the detection module on the heating pipe in a digital and concrete way, so that the operator can have an intuitive understanding of the flow of the thermal fluid in the heating pipe at any time, and make corresponding treatments to the heating pipe in time, adjust the valves on each pipe in time to ensure the normal heating work, and distribute the heating proportions to the residents' residences to ensure that enough heating can be allocated to the residents' homes.

[0033] Furthermore, in order to facilitate manual operation by the operator, the self-adjustable heat meter 1000 also includes an adjustment button, please refer to Figure 1 The adjustment button is arranged below the liquid crystal display screen, and the adjustment button is electrically connected to the control module and the display module 11. The operator can manually input the opening value through the adjustment button, so that the control module sends an electrical signal to the electric regulating valve 2.

[0034] In an optional implementation, in order to realize the control of the flow rate of the thermal fluid in the heating pipe by the electric regulating valve 2, the electric regulating valve 2 includes a valve body 21, a valve core, a second controller and a regulating mechanism 22, a fluid channel is formed inside the valve body 21, and the two ends of the fluid channel are respectively connected to the heating pipe, the first end portion of the valve core extends into the valve body 21 and forms a block to the fluid channel, the second controller is electrically connected to the first controller and the regulating mechanism 22, and the second end of the valve core is connected to the regulating mechanism 22. The second controller is electrically connected to the first controller to receive the electrical signal sent by it, and adjusts the position of the valve core in the valve body 21 by controlling the regulating mechanism 22, so as to adjust the size of the flow rate of the thermal fluid in the heating pipe.

[0035] Furthermore, in order to detect the position of the valve core in the valve body 21, the regulating mechanism 22 includes a position sensor and a driving member, wherein the position sensor is electrically connected to the second controller, and the output end of the driving member is connected to the valve core to drive the valve core to rotate. The position sensor is connected to the valve core to detect the relative position of the valve core relative to the valve body 21 and feed it back to the second controller, so that the opening and closing degree of the electric regulating valve 2 can be known through the position of the valve core, thereby understanding the flow of the hot fluid passing through the heating pipe and realizing the regulation of the flow. The regulating mechanism 22 drives the valve core to rotate in the valve body 21 to adjust the position of the valve core relative to the valve body 21, thereby changing the opening and closing degree of the electric regulating valve 2. In this embodiment, the driving member is a rotating motor, which can be a servo motor or a stepper motor, and is not specifically limited here.

[0036] In an optional embodiment, in order to ensure a stable signal connection between the ultrasonic heat meter 1 and the electric regulating valve 2, the ultrasonic heat meter 1 is electrically connected to the electric regulating valve 2 through a two-core shielded wire. The electrical connection between the two is achieved through the shielded wire, which minimizes the interference of external signals and ensures the normal regulation of the thermal fluid flow of the heating pipeline.

[0037] In an optional embodiment, in order to protect the self-adjustable heat metering instrument 1000, the self-adjustable heat metering instrument 1000 further includes a protective shell. The protective shell is respectively provided on the periphery of the self-adjustable heat metering instrument 1000 and the electric regulating valve 2 to protect the self-adjustable heat metering instrument 1000 from dust and moisture, and ensure its normal operation.

[0038] In this scenario, please refer to Figure 2 The ways to adjust the heating pipeline through the ultrasonic heat meter 1 and the electric regulating valve 2 include adjusting by detecting the instantaneous flow rate, adjusting by the user's heating area, and manual adjustment.

[0039] When adjusting by detecting the instantaneous flow, after the instantaneous flow set value is input into the ultrasonic heat metering instrument 1, the instantaneous flow value is monitored, and a closed-loop control is formed among the instantaneous flow actual value Qactual, the instantaneous flow set value Qset and the valve opening TV through the PID control mode. When Qactual>Qset, the ultrasonic heat metering instrument 1 outputs a command to reduce the opening TV value of the electric control valve 2, otherwise it increases until Qactual=Qset.

[0040] When adjusting by heating area, after inputting heating area and power consumption per unit area into the input interface of ultrasonic heat meter 1, ultrasonic heat meter 1 automatically calculates the required instantaneous heat setting value Pset and forms a closed-loop control among instantaneous heat actual value Pactual, instantaneous heat setting value Pset and opening TV of electric control valve 2. When Pactual>Pset, ultrasonic heat meter 1 outputs instruction to reduce TV value of opening of electric control valve 2, otherwise it increases until Pactual=Pset.

[0041] During manual adjustment, the operator can manually input a control opening value through the adjustment button, so that the control module sends an electrical signal to the electric regulating valve 2, and the electric regulating valve 2 maintains a constant opening according to the instruction, so that the flow of the thermal fluid in the heating pipe remains constant. In the remote mode, the ultrasonic heat meter 1 communicates with the host computer through the 4G network or virtual local area network to modify and issue the opening value of the electric regulating valve 2.

[0042] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
