Description

Technical Field

[0001] The utility model relates to the technical field of automatic control, in particular to a low-noise sleeve-type electric regulating valve. Background Art

[0002] The sleeve-type electric control valve is a common industrial automation control device, mainly used to adjust parameters such as flow, pressure, and temperature of fluid media. Its working principle is to use an electric actuator to drive the valve core to move within the valve body, thereby changing the flow area of ​​the medium and achieving flow regulation. Sleeve-type electric control valves are mostly used to be installed on tap water pipes to adjust the water pressure. Since tap water may contain a small amount of mud or impurities, after long-term use, some impurities will inevitably adhere to the inner wall of the control valve. These impurities hinder the movement of the valve core inside the control valve, resulting in abnormal noise or even malfunction of the control valve after prolonged use. In view of this, we propose a low-noise sleeve-type electric control valve. Utility Model Content
