Diaphragm pressure compensation vessel fitting

摘要

The fitting has a T-shaped housing (2), with a main flow channel (5) in the continuous T-bar (3), and a bypass channel in the upright (4). The bypass is divided by a wall (9) into intake and outlet channels (7,8). The dividing wall extend into the T-bar, where it has an aperture (10). This is part of the main flow channel, and forms the suction unit. A tubular body (12), formed by a Venturi nozzle, is fitted into the aperture in the dividing wall. A ring body of larger diameter is fitted into the T-bar downstream of the nozzle, forming a ring-gap passage from outlet channel into main flow channel.
