PRESSURE EXCHANGER SYSTEM WITH A VESSEL ELONGATION ABSORBER

摘要

A pressure exchanger is provided with an elongation absorber (50) having a housing element (70) configured for connection to a pressure vessel stand and an inner element (60) configured for connection to a high pressure feed check valve outlet wherein the inner element is slidable with respect to the outer element in response to an axial length changes of the pressure vessel. The inner element may comprise an annular element defining an internal cavity (62), the element having a leading (63) and a trailing edge (61), the annular element further comprising a flange (64) extending outwardly for receipt in a recess (76) formed in the housing element, the flange being of a smaller cross section than the cross section of the recess to allow sliding of the inner element with respect to the housing element.
