[0002] A flow regulating valve is a key component commonly used in mechanical equipment such as compressors. It is mainly used to regulate the fluid flow to ensure the stable operation of the system under different working conditions. The working principle of the flow regulating valve is usually to change the size of the valve opening, thereby regulating the fluid flow. It is widely used in fields such as refrigeration, air conditioning, gas compression, and liquid transportation. In a compressor system, most traditional flow regulating valves rely on manual adjustment, and the adjustment process often cannot achieve high-precision control. Especially in occasions where precise control of fluid flow is required, low adjustment accuracy may lead to flow fluctuations in the system, thereby affecting the working efficiency and stability of the equipment.
