Description

Technical Field

[0001] The present invention relates to the technical field of fluid control, and particularly to a temperature-controlled valve and a temperature-controlled driving method thereof. Background Art

[0002] In the fields of industrial automation, heating, ventilation, and air conditioning (HVAC), and fluid control, temperature-controlled valves are important devices to ensure the stability of system temperature. It achieves precise temperature control by adjusting the fluid flow rate and is widely used in heating systems, chemical reaction kettles, food processing, and industrial manufacturing scenarios. Currently, the control methods of temperature-controlled valves mainly rely on electric, pneumatic, or mechanical adjustment methods to meet different working conditions. However, despite certain progress in the existing technology, there are still many deficiencies, which affect the adjustment accuracy, response speed, and energy utilization efficiency of the temperature control system.

[0003] Existing temperature-controlled valves have problems of hysteresis and low precision in pressure regulation. Traditional pressure regulation methods rely on a single mechanical structure, such as spring loading or simple pneumatic actuators. This method reacts slowly when dealing with rapid temperature fluctuations and is difficult to achieve high-precision regulation. In addition, the structure of the pressure regulation component of the valve is relatively fixed and difficult to adapt to different pressure conditions, resulting in adjustment failure or a significant decrease in control precision under certain extreme conditions.

[0004] Currently, most temperature-controlled valves rely on fixed temperature setpoints for on-off control. For example, constant ratio regulation or timing regulation is used, which can meet basic requirements in a static environment. However, in the face of working conditions with large temperature fluctuations, the system is difficult to dynamically adjust according to real-time temperature changes, resulting in a decrease in temperature control precision. At the same time, without combining optimized adjustment strategies, the temperature control system often operates at a high energy consumption state, unable to effectively reduce energy consumption and increasing the operating cost. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a temperature-controlled valve and a temperature-controlled driving method thereof, which solve the problems of hysteresis and low precision in pressure regulation of existing temperature-controlled valves.
