Automatic softener
Brief Introduction
I. Working PrincipleThe hydraulic control valve utilizes water flow energy to drive dual turbines, which rotate metering and control discs via gear systems. The metering disc accumulates flow volume, while the control disc directs raw water pressure signals through valve chambers to automate valve switching. The QC-RST softener comprises two resin tanks (primary/secondary), a hydraulic control valve, and a brine tank. The valve alternates between tanks, ensuring continuous operation with one tank regenerating while the other operates. Regeneration brine is drawn via Venturi ejector, using softened water from the active tank. Different hardness levels require specific metering discs for proper cycling. Water hardness (Ca2⁺/Mg2⁺ ions) is removed through ion exchange with resin, releasing sodium ions. Saturated resin automatically regenerates using concentrated NaCl solution to restore sodium-form resin. II. Features, Inlet Requirements & Installation (1) Features 1. High automation with stable operation. 2. Program-controlled for reliable, hands-free operation. 3. Energy-efficient ejector brine draw eliminates salt pumps. 4. Compact design reduces footprint and installation costs. (2) Inlet Water Quality 1. Residual chlorine <0.1ppm 2. Turbidity <2 NTU 3.Fe <0.3ppm 4. Mn <0.3ppm 5. TDS <500ppm (3) Installation 1. Support piping to prevent valve stress. 2. Install backflow preventer for potable water connections. 3. Boost pressure if inlet <0.15MPa. 4. Drain pipe <6m, no valves, downward termination. 5. 220V power required (non-hydraulic models). 6. Use calcium-fortified salt, avoid iodized salt. III. Technical Specifications & Applications (1) Technical Features 1. Microprocessor-controlled cycles (backwash/brining/rinse). 2. Timed/volume-based regeneration ensures consistent soft water. 3. Integrated valve/tank design saves space. 4. Self-regenerating brine system with auto-level control. 5. Uniform flow distribution maximizes resin efficiency. 6. Corrosion-resistant materials. 7. Low consumption: <2% water loss, <100g salt/mmol, 10-40W power. 8. Configurable as single/twin tanks with time/flow control. (2) Advantages 1. Fully automated operation minimizes labor. 2. Stable output hardness ≤0.03mmol/L. 3. 50-year FRP tank lifespan with wear-resistant valve core. (3) Parameters 1.
