Device for automatically switching a feed flow from one to the other of two parallel branch lines of an emergency cooling system, especially in nuclear reactors
A device is described for automatically switching a feed flow from one to the other of two parallel lines branching from a feed line when a break occurs in one of the branch lines. The device includes a piston-controlled three-way valve situated at a location of the feed line at which the branch lines branch off, the three-way valve having an inlet connected to the feed line and a respective outlet connected to each of the branch lines. The three-way valve has a valve member normally closing one of the outlets and is operatively connected to a displaceable piston and actuable thereby for opening the normally closed outlet and closing the other of the outlets. A fixed throttle is disposed in each of the outlets. (Official Gazette)
