Abstract

493,595. Preventing incrustation. JUNKERS & CO. GES. March 11, 1938, No. 7631. Convention date, March 16, 1937. [Class 123 (i)] Water-softening solution is drawn from a container 23 into the water supply to a flow heater 10 by the suction produced by a Venturi passage 16 in the water supply pipe 12, and a valve device 21 automatically decreases the flow of solution when the water flow is increased and increases the flow of solution when the water flow is decreased. When the outlet valve of the heater valve is partly opened to deliver a relatively slow flow of '' boiling " water, the suction in the pipe 12 moves a diaphragm 27 carrying a valve member 30 in a passage 31, against the compression of a spring 34, and solution is drawn into the water at a predetermined rate. When the heater outlet valve'is further opened to deliver " hot water, the further movement of the diaphragm due to the increased suction in pipe 12 causes a second valve member 29 to move into the passage 31 and decrease the supply of solution. When the heater outlet valve is fully opened to deliver " warm " water, the valve 29 is seated and the supply of solution is stopped. The cone-shaped valve members may be replaced by a sleeve-shaped member. The suction in the water supply pipe also controls the supply of fuel to the burner. In a modification, a valve controlling the supply of solution is operated by the spindle of the water outlet valve through a spring-pressed diaphragm acted upon by the suction in the water supply pipe, and in a further modification, a valve controlling the supply of solution is operated in conjunction with the suction control by a temperature sensitive device attached to the tubes of the heater.
