METHOD AND APPARATUS FOR ADDING A LIQUID ADDITIVE TO A PRESSURIZED LIQUID FLOWING IN A CONDUIT

摘要

The method and apparatus of the present invention make it possible to inject a predetermined exact dose of additive liquid (such as chlorine solution) into pressurized water supply lines at various pressures without any changes in power consumption or mechanical strengthby using the pressure in the water supply line. Further, the design of the apparatus is such that deposits and external factors like sand will have no effect on its continuous operation, and the apparatus will be able to work for long periods without maintenance. In a preferred embodiment, no electricity is necessary for the injection of the additive.
