The Three-Way Mixing Valve Training Unit, "TEV3V", allows to demonstrate the function of a three-way mixing valve in a hot water heating system. The three-way mixing valve in the heating system regulates the supply water temperature to a heating system.
The unit includes a three-way mixing valve, a boiler water circuit, a return heating system water circuit, a circulating pump, several thermometers and flowmeters.
The boiler water line (hot water) and the return heating system water line (cold water) includes several dial thermometers and flowmeters to visualize the water temperature and flow in the inlets and outlet of the three-way mixing valve.
A pump circulates the mixture water in the system. The differential pressure across the system is limited using a differential pressure relief valve.
Several bleed valves (air vents) remove the air from water and are situated in different points of the circuits. Several valves allow control the boiler water flow and the return heating system water flow.
- Study of the function and operation of a three-way mixing valve.
- Study of the function and operation of a differential pressure relief valve.
- Study of the effect of mixing ratio on feed flow or circulating flow temperature.
- Study of the effect of mixer setting on the flow rate.
