In the petrochemical industry,heat pipe network and long-distance pipeline industry,the tra-ditional large-diameter manual valve is often equipped with a worm gear box(gearbox).Due to the low operating frequency,the opening and closing process is time-consuming and laborious,resulting in low efficiency.In order to solve this problem,this paper designs a new type of intelligent valve opener,which can cooperate with the existing manual valve worm gear box,and can realize automatic opening and closing by removing the hand wheel.This paper introduces the working principle,performance pa-rameters and structural design of the valve opener.Through the trial production and debugging of the prototype,the key links such as program control and connection size are optimized.The test results show that the opening and closing process of the intelligent valve opener is smooth and stable,which significantly improves the work efficiency,reduces the manual operation cost and enhances the opera-tion safety.
