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.
