Injector for service water mixer - consists of injector, branches, and thermostatically controlled three way valve

摘要

The injector is for forced circulation and regulated mixing water temperature, in a water supply with circulation plant. The injector (1) has three branches (2), and is positioned in the cold water feeding mains (9). The branches are connected to a cold water rising pipe (7) the cold water feeder to water mixer (4), and the cold water feeder to the three way valve intake (3c). The second valve intake (3b) is connected to the circulation pipe (8) and the valve outlet (3a) to the injector intake conduit (1a). The valve is thermostatically controlled, with a finely regulated temperature range, to determine the minimum mixing water temperature. A temperature feeler (3e) is located on/in the circulation pipe. ADVANTAGE - Compact simple construction, easy to install, without electrical assemblies.
