CONTROLLER OF PARAMETERS OF MIXTURE OF LIQUID MEDIA, DEVICE FOR OZONE TREATMENT OF WATER AND BATCHER OF LIQUID MEDIUM Russian patent published in 1998 - IPC

FIELD: control of parameters of liquid media, ozone treatment of water and metering of liquid media. SUBSTANCE: flexible diaphragm of batcher separates its two spaces. Inlet duct of batcher communicates source of metered medium with one of these spaces. Outlet duct of batcher communicates one of these spaces and position of media mixture. Actuating element of batcher is manufactured with capability of change of parameter of metered medium with change of pressure difference in spaces of batcher. Ozone generator may be used as source of metered medium. Active and metered media can be mixed in injector. Purified water can be employed as active medium. Actuating element of batcher may include two parts mounted for mutual translation. One of these parts is put on flexible diaphragm that has center rigid relative to it. This rigid center is manufactured in the form of seat or valve of actuating element. Valve is placed in flow duct of metered liquid medium. Batcher may have two flexible diaphragms that jointly form one of spaces of batcher. This space may be non-flow and connected by reference pressure duct to injector. In this case flow space of batcher should communicate with injector through valve actuating element. EFFECT: automatic control over needed parameter of metered medium with change of pressure difference downstream from its source. 20 cl, 2 dwg
