Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bypass valve actuators, in particular to a lightweight pressure relief structure for a bypass valve actuator. Background Art
[0002] The pressure relief structure in the bypass valve actuator mainly plays the role of adjusting the size of the fluid channel to control the fluid pressure. When the actuator receives the control signal, it controls the opening and closing of the solenoid valve to control the switch of the bypass valve. In this process, the pressure relief structure plays a key role. It helps to achieve pressure regulation and stability to ensure that the fluid system can operate smoothly and efficiently. Specifically, when the system pressure exceeds the set value, the pressure relief structure will automatically open and release part of the fluid, thereby reducing the system pressure and preventing equipment damage or safety accidents caused by excessive pressure. At the same time, when the system pressure is too low, the pressure relief structure will also be adjusted accordingly to maintain the stability of the system pressure. This flexible pressure regulation function makes the bypass valve actuator widely used in various industrial fluid systems, such as hydraulic systems, pneumatic systems, and water treatment systems. In these systems, the bypass valve actuator ensures the normal operation of the equipment and the stability of the system by accurately controlling the fluid pressure.
