from the boiler to a discharge pipe application_number US 61181684 A description referring to fig1 a boiler 1 has a heater and produces steam it is connected to the condenser 3 the steam from the boiler 1 is condensed in the condenser 3 the distilled water produced in this condenser 3 flows out through the outflow pipe 5 to the water storage tank 7 where it is stored inside the above mentioned distilled water storage tank 7 there is a float switch 9 which senses the level of the distilled water at the top of this tank 7 there is an overflow pipe 13 which is connected both to the tank 7 and to the water outflow pipe 1 in addition at the bottom of the tank 7 there is a regular stopcock 15 consequently by firing up the heater which heats the boiler 1 steam is produced which is supplied to the condenser 3 where it is condensed it then flows out and is stored in the tank 7 and can be drawn off to be used by operating the stopcock 15 along the water supply flow path 17 through which cooling water is supplied to the above mentioned condenser 3 there are a strainer 19 a flow rate control valve 21 which has a pressure compensator and maintains the flow rate constant regardless of fluctuations in the pressure of the primary water supply and a solenoid valve v1 which opens and closes the supply path in that sequence an overflow tube 25 is connected to the outflow.
