The main role of the return water pipe is to prevent the problem of liquid backflow during use, ensure the one-way flow of liquid, and avoid the backflow or mixing of liquid in the water supply system, so as to maintain the purity and efficiency of the system. Through the specific design and structure, such as sleeve, sealing sleeve, arc plate, first support rod, second support rod, roller fixing rod, roller and chute and other parts, the function of preventing backflow is realized, thus prolonging the service life of automobile water supply system, convenient for users to use
NIBD water pipes themselves are typically made of pressure-resistant, corrosion-resistant materials, such as specific rubber, to ensure good durability and tightness in a variety of environments in the car. The design and material selection of return pipes are also based on these considerations to ensure the reliability and longevity of their functions
