Application of valves in water treatment system:
Pressure reducing valve: it is used to regulate the pressure of tap water, ensure that the water pipe and water consuming equipment bear the pressure within the safe range and prevent excessive water pressure.
Check valve: installed at the water pump outlet to prevent water from flowing back to the water pump and protect the water pump.
Water mixing valve: used for mixing cold and hot water, providing constant temperature hot water, commonly used in water heater and solar system.
Application of joints in water treatment system:
Garden irrigation: Connect faucets, water pipes and sprinklers with connectors to realize automatic watering of gardens.
Water purifier connection: the connector is used to connect each filter element of the water purifier as well as the water inlet and outlet to facilitate assembly and maintenance.
Water pipe connection: in a complex waterway system, connectors are used to connect hoses of different lengths to form a complete water supply network.
