A method and apparatus for deaerating a liquid in a substantially closed fluid circulation system.

摘要

A method and apparatus for deaerating a liquid in a substantially closed liquid circulation system, wherein an amount of liquid is withdrawn from the circulation system and is introduced into a closed reservoir (1) via a valve (4) which is alternately open and closed, wherein by means of a pump (7) which is operative in the open as well as the closed positions of the valve an underpressure can be created in the reservoir (1) for the purpose of deaerating the liquid, and the liquid can be sucked from the reservoir (1) and added to the circulation system (8) again, separated air being discharged via a vent unit (2) to the environment. For the valve (4) adapted to be opened and closed alternately, preferably a throttling valve is used. IMAGE
