Fluorine-lined swing check valve H44 is a valve specially used to control corrosive or highly corrosive media. The inner surface of the valve body of this valve is covered with various fluoroplastics, which has the characteristics of high strength and good corrosion resistance. They can be applied to different working temperatures and fluid pipelines, prevent the backflow of media on various pipelines or equipment, and realize one-way opening and closing.
Working principle
The working principle of the H44 type fluorine-lined swing check valve is to automatically open and close the valve disc by relying on the flow of the medium itself to prevent the backflow of the medium. This valve is an automatic valve, and its main function is to prevent the backflow of the medium, prevent the reversal of the pump and the drive motor, and the discharge of the container medium. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis). By selecting different structural forms and materials, it can be widely used in various media such as water, steam, oil, acids, alkalis, etc.
