Background

The atmospheric safety valve is widely applied to units such as a steam turbine and the like so as to ensure that high vacuum is maintained during the operation of the units to meet the steady operation requirement of the units. The air safety valve needs to keep water overflowing to ensure the sealing performance of the turbine and other units, and the water used for the air safety valve is usually desalted water after treatment, so that corrosion of the water to all equipment in the unit is reduced, waste of desalted water is avoided because the water overflowed from the air safety valve is directly discharged, and the water overflowed from the air safety valve needs to be recovered.

The existing atmospheric safety valve overflow water is recovered in a closed way through a condenser, and the water quantity of the overflow water recovered in the condenser is difficult to directly observe in the closed recovery process, so that the water inflow in the atmospheric safety valve is difficult to adjust, and if the water inflow is large, part of water overflows out of the room from a discharge port on the atmospheric safety valve, so that the waste of the overflow water is caused; if the water quantity entering the atmosphere safety valve is smaller, the air can be sucked into the condenser through the sealing cavity due to poor sealing of the sealing cavity of the atmosphere safety valve, so that the vacuum of the steam turbine is influenced, the sealing performance of the atmosphere safety valve on the unit is further influenced, and the normal operation of the unit is influenced.
