During the use of the electric butterfly valve, if internal leakage occurs, it will directly affect people's use. What are the reasons for the internal leakage of the electric butterfly valve? How to solve this situation?
1. Affected by the processing and assembly process, the electric butterfly valve generally cannot be opened after manual closing. Even if the adjustment of the electric butterfly valve is ideal, since the operating position of the limit switch is relatively fixed, the medium controlled by the valve is Continuous scouring and abrasion of the valve during operation will also cause internal leakage caused by the valve being not tightly closed.
2. The traditional control method of controlling part of the electric butterfly valve is through mechanical control methods such as valve limit switch and over-torque switch. Because these control elements are affected by environmental temperature, pressure, and humidity, the valve positioning is inaccurate, spring fatigue, and thermal expansion. Objective factors such as uneven coefficients cause internal leakage of the electric butterfly valve.
3. After the electric butterfly valve is adjusted, after a certain period of operation, due to the cavitation of the valve and the erosion of the medium, the wear of the valve core and valve seat, the aging of internal components, etc., the stroke of the electric butterfly valve will be too large and the electric butterfly valve will not close. The severe phenomenon causes the leakage of the electric butterfly valve to increase. As time goes by, the internal leakage of the electric butterfly valve will become more and more serious.
Therefore, these reasons may cause internal leakage of the electric butterfly valve, so more attention should be paid during construction.
