The electric circuit and control program for outlet butterfly valve of circulating water pump have the problems that cannot be grasped in real time

and the opening degree and the opening speed of outlet butterfly valve cannot meet the operation requirements for circulating water pump. Combining with the actual operation needs

the electrical circuit of the butterfly valve was optimized and adjusted

and the local indication was added. At the same time

the butterfly valve control program was optimized

and the butterfly valve opening and valve opening control logic were improved

thus the safety

reliability and stability of the electric circuit and control program for outlet butterfly valve was ensured

effectively avoiding the occurrence of major accidents caused by the startup failure of the butterfly valve at the outlet of the circulating water pump and the untimely operation. Through the optimization and adjustment of electrical circuits and control programs

the purpose of guiding the operation in real time can be achieved.
