Circular slide valve exchanger for gases and liquids flow-metering - has exchangeable disc removable from measuring chamber housing

摘要

The measuring chamber housing is for flow metering of gases and liquids, which has co-axial connection pipes and incorporates an exchangeable disc diaphragm which can be removed for examination or exchange. The chamber housing comprises two steel plates which are screwed together and which have inlet and outlet pipes welded to them. In the plane separating the two plates a rectangular space is formed vertically to the axial direction of flow, in which the disc diaphragm is inserted into a retaining piece. After insertion, the space is pref. closed by a sealing plate and a pressure plate.
