The working principle of the butterfly check valve
When the medium flows through the valve body channel, the medium pressure is greater than the spring force, pushing the two butterfly plates open, the valve opens, and the medium flows; when the medium stops flowing, due to the spring force, the two butterfly plates are forced to reset, the valve closes, and the medium is prevented from flowing back. Butterfly check valve structure diagram Butterfly check valve is also called double-flap double-flap check valve. Its sealing surface can be welded with wear-resistant materials or lined with rubber. It has a wide range of applications and reliable sealing. Butterfly check valve is an automatic valve and does not require manual operation. This valve is usually used in pure pipelines, as well as industrial, environmental protection, water treatment, and high-rise building water supply and drainage pipelines to prevent medium backflow. Prevent medium from flowing in reverse.
