Pressure compensator container for hot water system

摘要

The pressure compensator container comprises an oval housing (1) with flanges (2) at each end to connect into a hot water line. The inside of the housing has a central pipe section (6) of flexible material with the ends clamped into the connecting flanges. The pipe section expands with the increasing water pressure as the water heats. The trapped volume (5) in the housing is filled with an inert gas, eg. nitrogen, which is compressed as the pipe section expands. The compensator is strengthened by a central rod through the housing which carries spacers to limit the compression of the flexible pipe section. An impeller mounted on the rod is rotated by the water flow and generates a swirl effect to prevent build-up of limescale and dirt etc.
