Abstract

PURPOSE: To solve the problem of damaging a feed water inlet by using an expansion to absorb movement of a slidable sleeve with the expansion at the feed water inlet.
CONSTITUTION: A partition sleeve 8 is fixed on the feed water inlet port 2 of a water room 1 and an expansion 12 is welded on it. One end of a partition wall 7 is fixed on a pipe plate 9 and the other is on an expansion-mounted sleeve 13. The sleeve 13 is movable on the sleeve 8. Water fed from the feed water inlet port 2 is heated while passging a heat tube 10 from a feed water inlet 5 and comes into a feed water outlet 4. Temperature difference causes between waters in the feed water outlet 4 and feed water inlet 5 while waters travel. The resulting expansion difference between the partition wall 7 and sleeve 8 may be absorbed by the expansion 12. And stress of the partition 7 deformed due to pressure difference between waters in the water room 1 and a body 11 may be absorbed by the expansion 12.
