The check valve for water system is mainly used in water systems to prevent the backflow of water. It usually consists of valve body, valve disc and spring and other components. When the water flows in the forward direction, the pressure of the water overcomes the spring force to open the valve disc, and the water passes through smoothly. Once the water flows in the reverse direction, the valve disc closes quickly under the action of the spring and reverse water flow pressure to prevent the backflow of water. The check valve for water system has a simple structure and high reliability. It can effectively protect the equipment of the water system and ensure the normal operation of the water system. It is widely used in water system fields such as water supply and drainage, fire protection and HVAC, providing an important guarantee for people’s lives and industrial production.
