Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an actuator for a three-way intelligent ball valve. Background Technology

[0002] The three-way intelligent ball valve, as a key fluid control component, is widely used in industrial pipeline systems to achieve the functions of diverting, merging, or switching the flow direction of media. Its core structure includes a three-way valve and an actuator (such as an electric, pneumatic, or manual operating mechanism). The actuator (electric) typically consists of a housing, control board, motor, drive shaft driven by the motor to rotate the ball of the three-way valve, control board, battery pack, solar panel, pressure sensor, switch, and other components.

[0003] However, existing three-way intelligent ball valves generally suffer from the problem of integrated design of the three-way valve and actuator. For example, if the actuator fails (such as motor damage or control board failure), the entire three-way intelligent ball valve needs to be removed and replaced. However, the three-way valve of the three-way intelligent ball valve is installed in the pipeline system and is very inconvenient to disassemble (it is necessary to drain the liquid in the pipeline system and disassemble the pipeline connection). This non-disassembly significantly reduces the availability of the equipment and increases the difficulty of maintenance.

[0004] Therefore, the applicant came up with a solution to detachably connect the three-way valve and the actuator. In this way, if the actuator fails, it is convenient to directly disassemble and replace it. At the same time, in order to facilitate the maintenance of some components inside the actuator, it is urgent to further optimize the design of the actuator. Utility Model Content
