This educational unit (PL102) is designed to simulate a household drinking water installation, this unit aims at illustrating how drinking water pipework -for one house- functions and how it is protected against backflow of waste water. A main unit is attached to the inlet and outlet of the trainer to drain or supply the unit with water in a closed cycle.
- This trainer can be used to investigate the function and operational behavior of safety devices for protection of back flow, as well as demonstration of pipework and fittings of a household drinking water installation.
- The unit is supplied with tap installment and a shower head to represent water supply in residential homes.
- A main unit consists of a tank and a pump is connected to the inlet and outlet of this unit to supply the unit with water and discharge the drain water to the main unit tank in a closed cycle system.
- The inlet water passes through a water meter to measure the delivered volume of water.
- Non return valves are installed along the pipes to prevent the backflow of the water stream.
- The unit is supplied with two lines for water, the first one is constructed for cold water stream while the second one is designed for the hot water stream.
- Cold and hot water streams pass through pressure regulating valves to control the outlet pressure.
- Heating tank is installed for the supply of hot water. Recirculation pump is installed to make sure that the water stays heated.
- A safety cycle is constructed and attached to the heating tank that consists of Safety valve and solenoid to discharge excess hot water in order to decrease the temperature.
- The heating tank is supplied with temperature sensor, pressure gauge and level sensor.
- Ball valves are installed on pipeline to allow or prevent water from flowing to the heating tank.
- Recirculation valve is installed in the hot water stream pipeline to allow or prevent the return water from flowing back to the tank.
- Two vents are constructed to discharge air from the cycle.
- Drain basin is made out of acrylic material.
