Leakage of high school butterfly valves is a relatively common problem, but in some important system equipment, once leakage of high school butterfly valves will affect industrial production and seriously harm the safety of the lives and property of the people. The power station high school butterfly valve is connected to the main equipment and system of the power station, and its importance is self -evident. The method of processing several power stations high school butterfly valves is analyzed below:

1. Leakage of high school butterfly valve fillers

The state of the valve stem and the filler will form a state of movement, which will be reflected in the use of high school butterfly valves. The more times the high school butterfly valve switch, the more exercise will be. In addition, the effect of temperature and pressure will greatly increase the possibility of the leakage of high -school butterfly valve filling. During this time, the pressure of the filler will gradually decrease, thereby aging, and elasticity does not exist. The pressure medium will leak outward from the contact between the filler and the valve stem. If this problem is not properly resolved, the problem of the seasoning and the departure of the valve stem out of the groove will be formed by the passage of time. Come bigger.
