Atmospheric safety valve!
Thread Content
What will happen if there is no water in the atmospheric safety valve during normal operation?
Normally, the air discharge safety valve is sealed with water, and the water is in an overflow state.； If there is no water and the safety valve is well sealed, the vacuum will not change much. ； If the safety valve seal is in normal or poor condition, the vacuum degree will gradually decrease, thus affecting the operating status of the steam turbine.
The lack of water will affect the back pressure, a large amount of air will enter the condensing system, and the condensation water content will rise.
