MEASURING, MONITORING AND CLEANING DEVICE FOR LIQUID FEEDING SYSTEMS Russian patent published in 2007 - IPC F16K37/00 G05D7/00 F24D19/10 

FIELD: engineering of armature for measuring, controlling, cleaning and stabilizing pressure for liquid supply systems, possible use, in particular, for supplying water in domestic buildings, cottages, and other consumers in any industrial branch involving supplying of a liquid component.

SUBSTANCE: measuring, monitoring and cleaning device for liquid feeding systems contains body, locking element, pressure regulator, liquid meter. Device additionally includes filtration and washing device. Locking element, pressure regulator, liquid meter and filtration and washing device are assembled in single case. Locking element is positioned in liquid inlet connection. Pressure regulator is positioned between liquid inlet and liquid outlet connections, and detachably connected to the case. By means of detachable connection, filtration and washing device is mounted in the case. This device is connected by a collector to pressure regulator hollow and the hollow after the locking element. A filter is mounted at the inlet of pressure regulator hollow. Liquid meter is mounted in the body by means of detachable connection. Outlet hollow of liquid meter is connected to liquid outlet connection. Its inlet hollow by means of another collector is connected to the pressure regulator hollow.

EFFECT: minimized dimensions of device due to combination of locking armature and filtering means in one unit, stabilization of pressure, recording of water (liquid) consumption, possible replacement of devices and elements of armature without disassembly of the whole device and without disabling the liquid feeding system and without requirements for its flush, measuring and monitoring elements are protected from dirt in working mode and during maintenance operations (washing).
