[0037] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0038] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0040] like Figure 1 As shown, an embodiment of the present invention provides a temperature control valve system, comprising a valve body having an electric valve actuator and a temperature control module connected to the valve body by signal. Figure 2As shown, the temperature control module includes a control unit and a temperature sensing unit, a communication module, an alarm unit and a display unit connected to the control unit. The electric valve actuator of the valve body is connected to the control unit by electrical signals, and the temperature sensing unit is used to collect the heating temperature of the heating device and send it to the control unit. The control unit is used to control the electric valve actuator to adjust the flow of the valve body according to the heating temperature, so as to regulate the heating temperature of the heating device.

[0041] It is understandable that the heating temperature of the heating device may need to be adjusted according to different processing techniques or procedures, and the heating temperature needs to be controlled within the corresponding predetermined temperature range at different processing stages. However, when the heating device is actually working, its actual heating temperature may be higher than the currently set threshold range, or it may also be lower than the currently set threshold range.

[0042] Therefore, in this embodiment, the control unit controls the electric valve actuator to adjust the flow of the valve body according to the heating temperature to regulate the heating temperature of the heating device, including the following two situations:

[0043] The first one: when the heating temperature of the heating device is higher than a set threshold range, the control unit controls the electric valve actuator to reduce the flow rate of the valve body.

[0044] After reducing the flow of the valve body, the flow of the heating fluid used to heat the heating equipment per unit time is reduced. When the heating temperature of the heating equipment is reduced to within the set threshold range, the flow of the valve body is stopped from being reduced. Through PID parameter setting or adjustment, fine-tuning is automatically performed in a timely manner to achieve the purpose of constant temperature.

[0045] The second type: when the heating temperature of the heating device is lower than a set threshold range, the control unit controls the electric valve actuator to increase the flow rate of the valve body.

[0046] After the flow rate of the valve body is increased, the flow rate of the heating fluid used to heat the heating device per unit time increases, and when the heating temperature of the heating device rises to within a set threshold range, the flow rate of the valve body is stopped from being increased.

[0047] Through the above adjustment method, the temperature control valve system can dynamically adjust the heating temperature of the heating equipment to meet the needs of different industrial production, without the need for frequent operation and monitoring by management personnel, reducing labor costs and the possibility of operational errors.

[0048] Furthermore, in order to facilitate management personnel to remotely monitor the temperature control valve system, the control unit is also used to send an alarm signal to the monitoring terminal through the communication module when the heating temperature of the heating device exceeds a set threshold range.

[0049] The alarm signal may carry the current heating temperature and the current threshold range of the heating equipment. The monitoring terminal may be a fixed terminal installed in the monitoring room, such as a monitoring host; the monitoring terminal may also be a mobile terminal carried by the management personnel, such as a smart phone, a tablet computer, and a wearable device.

[0050] After receiving the alarm signal through the monitoring terminal, the management personnel can promptly notify and organize relevant personnel to check the working status of the heating equipment and the working status of the fluid heating system on site to ensure production safety.

[0051] In this embodiment, according to the requirements of the working environment, the communication module can adopt a wired communication module or a wireless communication module. Among them, the wired communication module can adopt an Ethernet communication module, a CAN bus communication module or an RS485 communication module. The wireless communication module can adopt a Bluetooth module, a 4G module, a 5G module, a WiFi module, a lora module, a ZigBee module, a NB-IoT communication module or a GPRS communication module.

[0052] In this embodiment, the control unit is also used to control the alarm unit to issue an alarm message when the heating temperature of the heating device exceeds a set threshold range. The alarm unit includes an audible and visual alarm.

[0053] For example, when the heating temperature of the heating equipment exceeds the set threshold range, the control unit controls the sound and light alarm to start, and sends out an sound and light alarm to remind patrolling managers to pay attention and carefully check the working status of the heating equipment and the working status of the fluid heating system in time to ensure production safety.

[0054] The display unit is used to display the heating temperature of the heating device in real time, so that patrol personnel can check the current heating temperature of the heating device in real time. In this embodiment, the display unit can be a liquid crystal display or an LED display. The control unit can be a single-chip microcomputer, an ARM processor or a PLC controller. The temperature sensing unit can be a temperature sensor.

[0055] To sum up, the temperature control valve system provided by the present invention can accurately control the supply of heat or cold according to the temperature and demand of the heating equipment to avoid energy waste; achieve high-precision adjustment of the heating temperature of the heating equipment to meet different industrial production needs; do not require frequent operation and monitoring by management personnel, reduce labor costs and the possibility of operational errors, and can perform remote monitoring with a high degree of automation.

[0056] Finally, it should be noted that the various technical features of the technical solution of the present application can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of the present application.
